The modern industry produces many diverse cranes and valves to regulate fluid flow. For any scope, you can find suitable. However, the inquisitive minds of home masters do not leave attempts to develop and implement their own designs. Sometimes it is caused by the desire to save, but more often to check own forces As a designer, machine-building, locksmith and electrical engineering.
Trying to repeat the design of the conventional shut-off valve does not have a practical and economic meaning if the home workshop is not equipped with high-precision milling, turning and drilling machines. The price of industrial samples with mass production is also available to the most modest budget. Another business is technically complex shut-off for special applications, such as:
Options for their implementation will be discussed below.
Motorized valve can find its use in modern "smart" water supply systems, heating and air conditioning, created by domestic masters with minimal use of purchased components. In addition to checking its forces, there will be a significant cash benefit of the electric drive with an electric drive costs from 2 to 10 thousand rubles.
For a ball crane with an installed electric drive, made with your own hands, the following materials and components will be needed:
Figure 2: Power Supplier All electrical equipment by 12 volts. From the tools you need:
The generated mechanism should allow electrical crane to control both using the drive and manually. Production sequence as follows:
Next, you should try kinematics, feeding the voltage to the electric motor. Can be used car battery or power supply with a power of at least 50 W. The lever gear should move smoothly, without jerks and distortions. If necessary, to adjust the details of the file with a file.
Now there comes a queue of the electrical part of the drive.
Such a drive can be connected to the "Smart Home" system control circuits. Electrocaran for water made with your own hands will be economically effective if the windows drive will get inexpensively. New stands up to 1 thousand rubles, and can eat half of economy.
Instead of drive, you can use any other electric drive,

A needle valve with a large adjustment range can be collected from infirred materials with low costs. For its manufacture, it will be necessary:
Figure 4: Valve scheme The scheme indicates:
To make a crane, follow:
Figure 5: Finished design The incoming fluid will strive to press the ball from the inlet, the spring will join it back the stronger, the stronger the adjusting screw will be wrapped. If the screw is fully twisted, the flow will pass freely if completely twisted the flow will be blocked.
Those who have the need to use the plumbing on the site in winter time, face the problem of freezing of street crane. At high temperature drops, water inside the reinforcement and pipes turns into ice and can break them.
There are several ways to organize such water supply:
Figure 6: non-freezing valve 
Figure 7: Homemade non-freezing valve 
Figure 8: Three-way valve Full touch tonx homemade Master Making is unlikely to be under power. The main problem will be in placement and waterproofing infrared sensor Approximation. Enough interesting designallowing you to turn on and turn off the water with your hands, you can collect using
The installation procedure and settings are as follows:
When the water is no longer needed, it is enough to release the key, and the springs will return the valve into the closed state. Special attention should be paid to waterproofing of wires and connections.
Purchased flowing electrical heaters have a compact design and are equipped with a temperature control system, spill and aerator. To make such a nozzle on the crane with your own hands in the conditions of a home workshop hardly possible. The main problem is precisely processing parts and ensuring the electrical safety of the device. However, self-relocities have developed a simple and quite effective design, allowing to do without complex and expensive components. It works at the expense of heating the heat exchanger-coil on the gas or electric burner. For the manufacture of enough medium-sized skills.
From materials and tools will be required:
Work is carried out in the following sequence:
Figure 9: Homemade flowing water heater When this heater is working, it cannot be left unattended for a minute.
Summer is the most successful season for innocent water fun in the country and surrounding areas. Why at dachas? Because, I would not use this valve at home. What are we talking about?
Let's try to figure out.
And so, proceed!
In fact - this part of the automation for me is completely unexplored
However, I would like to find a yobgetic option for experiments. Fortunately, there is a cottage and often, for certain reasons, the possibility of my presence on it does not coincide with the desired schedule of the distribution of water ... What is exactly what you need?
Mass options - automatically distribute water to certain sections of the cottage, automatically pour an additional capacity (because water supply by time is limited, and water pressure does not allow you to do everything at once).
Thread 1/2, the external casing is missing, the coil is cast, at the inlet to the valve - the metal mesh, on the body - the water supply arrow (input-output), the principle of operation - the membrane, under the action of the spring, the closing valve. The valve is normally closed.
The seller sends with a track that is absolutely not tracked.
Seller data: 
Data from the device:
I immediately want to say, the seller's data does not coincide with reality, although the data on the nameplate is more reliable (except for zero pressure).
First, and this is the most important factor - for low pressure systems, the valve will not work! He needs a porch to open the furniture.
Secondly - current consumed by the coil in 2! (Two) times more - 430 mA, and with long work, it is significantly heated. True, the valve begins to open around 7-8 V.
Now proceed to the preparation of the patient:
We unscrew the 4 screws and see: a whole-lit plastic frame, a rubber valve, a cylindrical flask, in which the metal core and spring is located, which suppring the valve in a closed vacuum. On the left of the photo - the water inlet, on the right - the exit.
As can be seen, there is a threat of leakage and there is a threat to failure due to not protected from rust core and springs.
Pros: simplicity of design, low cost.
Cons: plastic thread and hull, large current consumed, lack of additional sealant except rubber membrane, the impossibility of using in systems with low pressure.
It remains to check it in combat conditions.
I plan to buy +39. Add to favourites I liked the review +25 +55This system of auto watering plants can make any person, without knowledge of electronics, and not even able to solder radio elements. The system uses ready-made devices that need to be simply connected in a certain sequence and enjoy the result of automatic irrigation.
You can collect this simple innovation in more than one hour, but for this you need to order or buy all the elements of the system.
I used the electromagnetic valve in the system. There are plays here:
- With a sudden disconnection of the light, your site will not fill with water, as the valve will close, in contrast to the electromechanical.
- Ease of Management. There is a voltage - the valve is open, no voltage - the valve is closed. Everything is simple. And the electromechanical need to be able to manage.
To work the system, you need: a free outlet with a voltage of 220 V and plumbing.
As a result, it was not necessary to collect and set up a lot of time and labor. If you read this article, also decided on the construction of this miracle, then ready-made timers with built-in valves and autonomous food appeared on sale, which I certainly didn't know when I collected the system.
Here they are. Food from batteries. 
Operation of pipelines various destination It assumes that liquid and gaseous media, which are transported according to them, should move in a certain direction. Having made the return valve with your own hands or by purchasing its serial model, you can provide this requirement of the operation of the pipeline and the elements of its equipment, which will allow for a long time to maintain them in a working condition.
Reverse stream in pipeline systems may occur for different reasons. If we are talking about liquid environments, the pump can be turned off, and in the case of ventilation - incorrect installation of an exhaust pipe or a small amount of incoming air. Whatever causes the occurrence of the reverse flow of the working medium in the pipeline system, such a phenomenon is extremely undesirable, as it can lead not only to the incorrect operation of the elements of such a system, but also to their failure.
To prevent education in the reverse flow system, as already mentioned above, it is set to check valves that may differ as their external species and dimensions and constructive execution. The main function of such a device installed on pipelines for which liquid and gaseous media are transported is to skip the workflow in one direction and block its move at the moment when it starts to move in the opposite direction.
The design of the check valves, regardless of their type, is the following elements:
The principle of the reverse valve is simple and lies in the following.
On the modern market A set of check valves is proposed. different typesWhich allows you to select such devices for solving certain purposes. Meanwhile, many homemade craftsmen, guided by the natural desire to save, make check valves with their own hands and are divided with drawings and schemes of their homemade on the Internet.
Homemade check valve for installation on a pipeline for which water is transported does not require in the manufacture of expensive supplies and complex equipment, which makes it possible to save well. So, to independently make the check valve, you must prepare:
Spring, if you did not find a suitable diameter, can be made and independently using the rod of the corresponding diameter and rigid steel wire. In the rod to which the homemade spring will be hung, you must drill the hole, the end of the wire will be inserted into it. To pump the spring it was more convenient, the rod can be clamped in vice, and the wire itself is performed using pliers.
After all the materials for the manufacture of homemade check valve are prepared, you can start assembling, which is performed in the following sequence.
The return valve, made according to the proposed scheme, will be as follows: The water flow included in such a device from the coupling, will repel the ball, pressing the spring, and exit through the perpendicularly located hole of the tee.
The most important thing in the manufacture of the back valve of the proposed design - properly adjust the spring so that it does not deviate at the moment when the water pressure in the pipeline will decrease, and at the same time it was not too tight, so as not to prevent the flow of water passing through the device. In addition, it is necessary to perform all threaded compounds to perform all the threaded compounds to ensure the absolute tightness of the check valve.
The question of how to make a check valve to equip the ventilation system is no less relevant than the manufacture of a similar device for water supply or sewage. Setting the check valve in ventilation systemYou reliably protect your dwelling from polluted and cold air entering such a system from the outside.
It should be noted that the reverse valve of the proposed design, if compared with serial models, has no less efficiency and is able to successfully serve you for two or three years.
So, the manufacture of a self-made check valve for equipping the ventilation system is performed in the following sequence.
The final stage of installation of the self-made return valve in the ventilation system is the cutting of the film pasted on the plate, two identical halves. Performing such a procedure for which it is best to use a sharp mounting knife, it is necessary to ensure that the slice turns out to be flawlessly smooth.
The principle on which the back valve works proposed above, is quite simple and is as follows.
Thus, this check valve belonging to membrane Type, reliably protects the ventilated room not only from polluted and cold air, but also from strangers.

When using water supply and heating systems, no one is insured against emergency situations. Minimize risks and loss in the event of a breakthrough allows an electromagnetic (solenoid) water valve. This device allows you to quickly overlap or, on the contrary, open the flow of water in a few seconds, while at a distance. We will analyze in detail how the electromagnetic, species, principles of its operation and installation are arranged.
The solenoid valve is a shut-off valve, which closes the aqueous stream, allows you to control the speed of fluid movement in the pipeline. These devices are called electromagnetic, as their principle of operation is built around an electromagnetic coil (solenoid). There are several types of similar products and each has its own characteristics and differences in principle.
Automatic tap shutter includes such components:
The housing of such aggregates is usually done from materials such as brass, stainless steel (in order to increase resistance to corrosion) and cast iron. Plugged plumbing electromagnetic valves made of plastic.
Plungers and stocks are made from materials that have magnetic properties. Electromagnetic coils are placed in a special protective housing, which has sufficiently high tightness parameters. Winding for coils, as a rule, is made of copper wire or enameled wire. Such devices begin to work after a voltage is supplied to the coil.
Electromagnetic or in other words induction coil converts electricity to protective traffic. The most common are coils with copper winding on the cylinder. The cylinder includes a magnetic plunger. As soon as the coil is supplied, the magnetic field appears. As the result of the magnetic field, the core is drawn into the coil.
Product membranes are made of polymeric materials that have high level Elasticity. These materials include the following:
Valves can be made of the most different materialsThe hull is made of plastic, brass or cast iron.
In the event that there is a need to overlap the flow of the transported medium, a pulse is supplied from the control unit to the induction coil. Thanks to this signal, the device core rises either down (it all depends on the device configuration) and overlaps the fluid flow. Immediately after the voltage disappears, the core returns to the initial position and the fluid movement is resumed.
The main advantage of the electromagnetic valve on the water is that it allows you to quickly adjust the flow of the transported medium in the system. To perform their functions, the device must only be 2-3 seconds. Because of this, the solenoid model is a rather important device in water supply systems of apartments and private houses.
It also makes it possible to adjust the temperature control of the coolant flow. The electromagnetic device allows you to smoothly distribute the temperature in the heating system, which prevents contamination. And this directly allows you to extend the life of the entire heating system.
Due to the fact that the device in its design does not have a quick mechanical detail, solenoid models are more reliable. Such a device can be mounted in systems with the most different pressure indicators, since this feature Does not affect his work.
It is due to such characteristics that electromagnetic models occupy dominant positions among the shut-off valves on the market.
Automatic tap shutter is a sufficiently useful device that is used in a wide variety of spheres. This unit is successfully used in various branches of home and national economyAnd besides in various manufacturing industries. A plurality of air ducts and water pipes of varying degrees of construction complexity successfully use this product in their work.
Equipment with solenoid drive most popular in structures where most of Devices work on the principle of automatic control. Mainly the choice of the scope is determined, based on the material from which the valve is made. Such devices can be found in washing machines, sewage systems, irrigation systems, to control hydraulics systems, heating systems and many others.
He received the greatest popularity in:
In addition, electromagnetic models are used to adjust and control the transportation of various aggressive media in production. Devices used in production can be quite large diameter. It is strictly prohibited by the use of brass models when working with aggressive substances, such as, for example, diesel fuel or acid.
The solenoid valve (its kinds) is two categories, the main difference of which is their principle of operation to turn on and off the mechanism:
In addition, they are several basic species that have their own functional features. Devices are:
By type the coils of the device are divided into:
In addition to the aggregates are divided by type of operation:
Singo-like only one nozzle and they cannot combine different streams of liquids. Two-way and two nozzles (input and output). The principle of operation of the one-step and two-way device acts on the functioning of a ball or cone, which is used for closing.
Three-way solenoid valves for water in their design have as many as three pipes and can work on the basis of mixing fluid flows. In addition, the devices of this type can control and adjust the temperature using the mixing of water flows. There are also explosion-proof models used in operation with explosive media. These valves are made and refractory and durable materials. There are also vacuum valves.
By type of connection with the pipeline are divided into:
Helpful information! There is a special type of devices called shut-off. This type of device can instantly disconnect the pipeline or clog one of the pipes during the accident.
Adjustable and locking valves must be selected and mounted, only relying on the calculations produced earlier. Use one or another type of valve (normally closed, two-way, direct action, etc.) is necessary depending on the type of pipeline and on what type of medium is transported over it.
Valves are used in a wide variety of media that have their own individual temperature and pressure indicators. The selection of the type of device must proceed from the characteristics of the medium, otherwise the device may not last long.
There are several key characteristics for which you need to pay attention when choosing an electromagnetic valve. The main parameter is the diameter of the input and outlet.
The range of electromagnetic devices is quite large. They possess different distinctive features In the design. But usually it does not greatly affect the operating parameters. One-bedroom electromagnetic devices can be called the most popular, in which the bandwidth reaches 40 l / min.
Important! Before purchasing the valve, it is necessary to pay special attention to the mechanical regulator built into the device. He may have several modes. The more their number, the better the system will be monitored.
In the case when the valve is required with as high bandwidth as possible, you can purchase the device of the SVR series. With a normal closed position, the valve of this series may have a fluid skip indicators up to 100 liters / min. Valve prices differ in their quality characteristics.
During the installation and operation of solenoid valves, the following points must be taken into account:
Compliance with the rules installation work And the requirements of the instruction manual will extend the service life of the device, which stabilizes the working pressure of the medium inside the system.
Problems When working this device, it is often due to the following problems:
To lead to a malfunction of the solenoid valve of normal-closed, even a banal hole of the hole.
Inspection of the internal elements of the water valve should be carried out only with a completely empty system. Independent execution of complex repair is not recommended.
