Problems solved by technology

It can be seen that the pressure regulating device of the existing diaphragm stabilizing pump has a large number of parts and types, not only the manufacturing cost of the parts is high, but also the assembly operation steps are cumbersome, the assembly error rate is high, and the assembly efficiency is low, resulting in the production of the diaphragm stabilizing pump as a whole. Increased cost and low production efficiency

Abstract

The invention relates to a diaphragm stabilized-pressure pump. The diaphragm stabilized-pressure pump comprises a pump main body and a pressure regulating device, wherein the pump main body comprisesa water inlet chamber and a water outlet chamber; the pressure regulating device comprises a sealing pad; the sealing pad is connected onto the pump main body in a sliding manner through an interference fit mode, and can isolate the water inlet chamber from the water inlet chamber or can enable the water inlet chamber to communicate with the water outlet chamber. Through the interference fit mode,the sealing pad is connected onto the pump main body in the sealing manner, so that a valve body part for fixing the sealing pad can be omitted, and a plurality of bolts for valve body mounting use are also omitted, and therefore, types and quantity of parts of the pressure regulating device are favorably reduced, the assembly steps of the diaphragm stabilized-pressure pump are simplified, the assembly error rate is reduced, and assembly efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of pump body equipment, in particular to a diaphragm pressure stabilizing pump. Background technique [0002] Diaphragm stabilized pumps are widely used in water purification equipment and other fields. The outlet pressure P2 is greater than the inlet pressure P1, and the outlet pressure P2 can be adjusted by the pressure regulating device installed in the diaphragm stabilizer pump. Specifically, the water flow enters the water inlet chamber of the pump body from the water inlet of the diaphragm stabilized pump, and the motor drives the diaphragm to reciprocate up and down. When the diaphragm moves downward, water can be sucked into the diaphragm pressurization chamber through the water inlet valve at the water inlet chamber. ; When the diaphragm moves upwards, it compresses the water in the diaphragm booster chamber to increase the water pressure, and the water is discharged into the outlet chamber through ...
