Water stoppage self-closing valve

How it works

Water supply status, valve cavity pressure is greater than the valve core shutdown pressure, Valve core has been in the upper end of the valve cavity, the water at the inlet can pass smoothly through the outlet. When the water is stopped, the pressure in the valve cavity is gradually reduced, and when the pressure of the valve core spring is greater than the pressure in the valve cavity, the valve is automatically closed. There is also a stop function. The water in the tube will not be siphon into the supervisor's path. When you come back to the water, you won't run the water because you forget to turn off the faucet. Pull the starting wheel or overpressure state to rotate the opening nut, that is, restore the water supply
