Structural use of diaphragm type rain shower valve

The diaphragm type rain shower alarm valve mainly uses a diaphragm to divide its main valve into upper and lower chambers, and the upper chamber is a control chamber. In this way, the main valve is sealed by utilizing the difference in the area of the upper and lower chambers to generate water pressure In the event of a fire, there are three ways to control the main valve to open the fire. After the main valve is opened, the pressure enters the pressure switch and the hydraulic alarm, and the hydraulic alarm sounds; the pressure switch controls the signal or turns on the fire pump. The diaphragm deluge valve has an anti-reset structure. After the main valve is opened for 10%, the anti-reset device is automatically activated to prevent the main valve from returning due to misoperation. After extinguishing the fire, cut off the transmission pipe network, close the solenoid valve, manual ball valve and end ball valve to close the main valve.

The diaphragm type rain shower alarm valve also has three functions, namely reasonable structure and beautiful appearance; convenient and reliable control and operation; built-in anti-reset device. It can be seen that its structural use is very Nice!
