Abstract

The invention relates to the technical field of lubricating equipment, in particular to a one-way valve. The one-way valve comprises a valve element seat, a valve element, a seal ring, a filter membrane and grooves. The valve element is disposed on the valve element seat. The seal ring is disposed between the valve element seat and the valve element. The filter membrane is disposed at one end of the valve element seat. The grooves are formed on two sides of the valve element seat. The one-way valve is simple, compact and reasonable in structure, convenient and fast to assemble, reliable in connection and easy to use and popularize, sealing performance of the one-way valve is enhanced, oil leakage can be prevented effectively, the risk that the one-way valve is blocked is lowered, cleanness of oil in an oil tank and oilway safety are guaranteed, service life of the one-way valve is prolonged, and working reliability of the one-way valve is increased greatly.

Description

technical field [0001] The invention relates to the technical field of lubricating equipment, in particular to a check valve. Background technique [0002] The sealing performance of the existing one-way valve is relatively poor, and it is prone to oil leakage. At the same time, the risk of the one-way valve being blocked is increased, and it is difficult to ensure the cleanliness of the oil in the tank and the safety of the oil circuit. The service life of the valve greatly reduces the reliability of the check valve. Contents of the invention [0003] In order to overcome the disadvantages of poor sealing performance, short service life and low working reliability of the existing one-way valve, the invention provides a one-way valve. [0004] The technical solution adopted by the present invention to solve the technical problems is: a check valve, comprising a valve core seat, a valve core, a sealing ring, a filter membrane and a groove, the valve core seat is provided w...
