Structure of
see figure, multi-function water pump control pneumatic valve structure of pneumatic valve and outside by the main accessories. Main pneumatic valve including pneumatic valve, main pneumatic valve plate, slow breath valve plate, pneumatic valve stem, pneumatic valve seat and the diaphragm controller ( Including pneumatic valve cover, diaphragm, diaphragm, diaphragm pressure plate) : outer attachments with control pneumatic valve, pneumatic valve, filter, emptying micro block back to the pneumatic valve. The micro block back to the pneumatic valve is special accessories, in the direction of the check have limited flow hole. Working principle of the
before starting the pump, pneumatic valve outlet pressure pneumatic valve on the main board, pneumatic valve in the closed position, the controller of diaphragm chamber connected pressure water on at the same time, inferior vena with low pressure pneumatic valve inlet side is same.
the pump starts, pneumatic valve inlet pressure increased, at the same time the pressure of water through the pneumatic valve inlet end connection tube slowly into the inferior vena diaphragm controller, realize the main pneumatic valve plate slowly open, open the speed can be adjusted by controlling the pneumatic valve.
the pump stop, pneumatic valve inlet pressure is reduced, when close to zero flow, main pneumatic valve plate quickly shut down under their own gravity. Pneumatic valve for pneumatic valve inlet side pressure is reduced, the outlet pressure of water through the connecting pipe into the controller of diaphragm chamber, inferior vena water through the pneumatic valve inlet side connecting pipe pneumatic valve inlet pressure back to the end, slow breath slowly closing valve plate, slowly closing time can be adjusted by controlling the pneumatic valve. Main pneumatic valve plate of gentle breath move quick closing valve plate slowly-closing conforms to the law of two-phase closed, can effectively eliminate water hammer.
