Problems solved by technology
[0003] The existing high-pressure plunger pump valves have certain disadvantages in use. When the plunger reciprocates, a part of the pump oil will flow back under the action of pressure and flow out from the oil inlet pipe to feed the high-pressure plunger pump valve. The use of the reservoir has brought a certain impact, therefore, we propose a high-pressure plunger pump valve for the reservoir

The invention relates to the field of pump and valve equipment, in particular to a high-pressure plunger pump valve for reservoirs, which includes a pump valve inner cavity and a rotating sleeve. There is a No. 1 spring, a ring gear is movably installed on the upper end of the rotating sleeve, a plunger sleeve is fixedly installed on the upper end of the ring gear, and a plunger is movably installed inside the plunger sleeve. An oil delivery pipe interface is fixedly installed on the top, and a sealing ring is provided on one side of the inner surface of the oil delivery pipe interface, and an oil inlet pipe is fixedly installed on one side of the plunger sleeve close to the oil delivery pipe interface. A high-pressure plunger pump valve for a reservoir according to the present invention is provided with a check valve, a movable piece, a long-diameter cam and a sealing ring, which can avoid the phenomenon of oil backflow in the oil inlet pipe, and can increase the pressure of the plunger pump valve. At the same time, it can enhance the tightness of the connection between the interface and the oil pipe, bringing better prospects for use.
Description
technical field [0001] The invention relates to the field of pump valve equipment, in particular to a high-pressure plunger pump valve for a reservoir. Background technique [0002] The high-pressure plunger pump is an important part of the hydraulic system. Through the reciprocating movement of the plunger inside the pump chamber, the volume in the sealed pump chamber changes to generate a pressure difference, so that the pump valve of the high-pressure plunger pump performs oil suction and pressure. Oil operation, the rated pressure of the high-pressure plunger pump is high, and the flow adjustment is more convenient, so the high-pressure plunger pump is widely used in occasions such as reservoirs with large flow or flow adjustment. [0003] The existing high-pressure plunger pump valves have certain disadvantages in use. When the plunger reciprocates, a part of the pump oil will flow back under the action of pressure and flow out from the oil inlet pipe to feed the high-p...
