[0002] A one-way valve is a valve that allows fluid to flow only along the inlet, but not back through the outlet. It is commonly known as a one-way valve. A one-way valve is also called a check valve or a non-return valve. It is used in hydraulic systems to prevent oil from flowing in the opposite direction, or in pneumatic systems to prevent compressed air from flowing in the opposite direction.

[0003] After searching, the existing patent (publication number: CN103511683A) discloses a wear-resistant one-way valve, which includes a stop pin, a valve body and a steel ball; the inner hole of the valve body is a stepped hole composed of a large hole and a small hole, and a wear-resistant ring is embedded between the large hole and the small hole. The wear-resistant ring material is hard alloy, and a conical sealing surface is set on the left end face of the wear-resistant ring; the steel ball is placed in the large hole of the valve body, and the stop pin is placed at the left end of the large hole of the valve body, penetrating the wall of the large hole. The conical sealing surface wears very little during operation, and the service life of the one-way valve is doubled; on the other hand, the valve body only needs to use ordinary materials and does not require heat treatment, which simplifies the process.

[0004] The wear-resistant ring material used is cemented carbide, so the wear is small and the service life of the one-way valve is doubled. However, it has its shortcomings. The limit of its wear resistance is the limit of the material and is closely related to the material. Utility Model Content
