Background technology
In traditional diaphragm pump, for increasing sealing property, using seal membrane, the hydraulic pressure owing to producing in valve body reaches as high as the high pressure of 2MPa, and the pump housing operationally push rod drives seal membrane ceaselessly to move up and down, and causes diaphragm to there is the risk of positioning.
Accordingly, it is desirable to provide a kind of diaphragm pump is to solve above-mentioned technical problem.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of diaphragm pump, sealing effectiveness is improved with the seal membrane withholding position by turnover water cover, valve body, base plate, seal membrane can be avoided because push rod pulls to cause diaphragm positioning, and then can strengthen and lead exhausted effect, reduce leakage accident.
This utility model solves the technical scheme of above-mentioned technical problem and is to provide a kind of diaphragm pump with following structure, including turnover water cover, base plate, push rod, it is limited in the valve body between Inlet and outlet water lid and bottom plate, seal membrane it is provided with between valve body and base plate, described seal membrane is fixed on push rod by retention mechanism, push rod is arranged on base plate, described valve body, seal membrane, base plate, push rod is each provided with 3 circular ports with matching, seal membrane includes at least one first annular flange towards turnover water cover, seal membrane includes at least one second annular flange flange towards base plate, the annular groove of accommodating first annular flange it is provided with at turnover water cover and valve body opposite position, the annular groove of accommodating second annular flange flange it is provided with on base plate.
In a preferred embodiment of the present utility model, retention mechanism includes 3 fastening screws and 3 annular pressing plates, fastens the looping pit on screw precession annular pressing plate, seal membrane, base plate successively and then is fixed on push rod.
In a preferred embodiment of the present utility model, described seal membrane includes 3 first annular flanges towards turnover water cover, seal membrane includes 2 the second annular flange flange towards base plate, it is disposed an outwardly facing the 3rd annular flange flange of seal membrane on valve body, corresponding seal membrane is provided with the groove of accommodating 3rd annular flange flange.
Beneficial effect: the diaphragm pump that this utility model provides, sealing effectiveness is improved with the seal membrane withholding position by turnover water cover, valve body, base plate, seal membrane can be avoided because push rod pulls to cause diaphragm positioning, and then can strengthen and lead exhausted effect, reduce leakage accident.
