When the downstream pressure is greater than the set pressure, copper check valve automatic controller according to the procedures set by the normally open electromagnetic magnet valve control a switching action, to the pressure regulating cavity filled with a small amount of water, the flow area decrease of diaphragm magnet valve, the downstream pressure is reduced, the interval after a certain period of time, if the downstream pressure is greater than the set pressure, repeat the movement at a time, until the downstream pressure on the stability of the set pressure near. When the downstream pressure is less than the set pressure, the gas stove safety valve automatic controller for control of a normally closed solenoid magnet valve for an open, close the action, the pressure regulating cavity of a small amount of water discharge to the downstream, the flow area is increased diaphragm magnet Gas Water Heater Valve, the downstream pressure is increased, the interval after a certain period of time, if the downstream pressure is still lower than the set pressure, solenoid repeat the last action magnet valve, and downstream pressure stable in the range of the set pressure value.
当下游压力大于设定压力时,阀门自动控制器根据设定的程序控制常开电磁阀做一个开关动作,向调压腔内充入少量的水,减小隔膜阀的过流面积,下游压力则降低,间隔一定时间后,如果下游压力仍大于设定压力,则重复一次该动作,直至下游压力稳定在设定压力附近。当下游压力小于设定压力时,阀门自动控制器控制常闭电磁阀进行一次开、关动作,使调压腔内的水少量排向下游,则增大隔膜阀的过流面积,下游压力则升高,间隔一定时间后,如果下游压力仍小于设定压力,则电磁阀重复上一个动作,直至下游压力稳定在设定压力值范围内。
