1, before water pump is started, ValvePlace is quiet pressure close position. After water pump is started, water fromValveThe bypass conduit that imports end enters the antrum below diaphragm room, lever of a powerful person of diaphragm along with and young a powerful person board slowly raise. Meanwhile, greatly board of a powerful person is being used into hydraulic master piece also immediately open.

2, increase as what take discharge and pressure, lever of a powerful person of diaphragm along with and big, young a powerful person board rise to rated height (but intuitionistic signal lever) .

3, when water pump stops, ValveGet together into saliva discharge stop, pressure is reduced, greatly board of a powerful person is in self-prossessed fall to glide quickly with backwater pressure action, till contact valve base completely.

4, increase as backwater pressure, water enters the antrum on diaphragm room from the bypass conduit that exports end, urge lever of a powerful person of diaphragm along with and lever of young a powerful person and young a powerful person board slowly next moving. Right now, the water of the antrum below diaphragm room passes the bypass conduit regurgitate of valve left to import end. When young a powerful person board shut big a powerful person or family completely board when shedding a mouth with the annular discharge between lever of a powerful person, ValveBefore restoring completely to be started to water pump again static pressure close position.

CompleteAccuse water valve automaticallybreakdown reason and eliminate step

One, signal lever rises fall the reason with abnormal speed is:

1, bypass young a powerful person or filter jam;

2, pressing plate or balata diaphragm burst or model piece the room is sundry and too much;

3, young a powerful person is shut artificially.

2, the step that eliminates breakdown is:

1, the handle place that checks bypass young a powerful person whetherCorrect;

2, clean young a powerful person and filter;

3, room of examination balata diaphragm, if balata diaphragm or pressing plate burst must change instantly.

3, inside the reason with too big leak is:
