Summer is the best season for innocent water fun in the country and surrounding areas. Why in the country? Because, I would not use this valve at home. What are you talking about?
Let's try to figure it out.
So, let's get started!
In fact, for me this part of automation is completely unexplored so far,
however, I would like to find a budget option for experimentation. Fortunately, there is a summer cottage and often, for certain reasons, the possibility of my presence on it does not coincide with the desired schedule for the distribution of water ... Why is this necessary?
Weight options - automatically distribute water tocertain areas of the cottage, automatically pour an additional capacity (since the water supply is limited in time, and the water pressure does not allow you to do everything at once).
1/2 thread, no outer casing, coilcast, at the valve inlet - a metal mesh, on the body - a water supply arrow (inlet-outlet), the principle of operation is a membrane, under the action of a spring, closing the valve. The valve is normally closed.
The seller sends with a track that is absolutely not tracked.
Data from the device:
I want to say right away that the seller’s data do not coincide with reality, although the data on the nameplate are more reliable (except for zero pressure).
Firstly, and this is the most important factor - for low pressure systems, the valve WILL NOT work! He needs a boost to open the mebran.
Secondly - the current consumed by the coil in 2! (TWO) times more - 430 mA, and with prolonged use, it is significantly heated. True, the valve begins to open around 7-8 V.
Now proceed to the preparation of the patient:
We turn off 4 screws and we see: a whole molded plastic frame, a rubber valve, a cylindrical flask, in which there is a metal core and a spring supporting the valve in a closed condition. To the left of the photo is the entrance of water, to the right is the exit.
As you can see, there is a threat of leakage and there is a threat of failure due to insecurity from the core and spring rust.
PROS: simplicity of design, low cost.
DISADVANTAGES: plastic thread and housing, high current consumption, lack of additional sealant other than a rubber membrane, the inability to use in systems with low pressure.
It remains to check it in combat conditions.
