摘要： A ball non-return valve that can be integrated with a diaphragm pump or the like, does not transmit strain generated by stress during valve assembly to a ball seal portion, and can stably maintain sealing performance, and a diaphragm pump are disclosed. The non-return valve includes a valve seat having a through-hole, and a ball that opens and closes a flow of a fluid through the through-hole. The valve seat made of a corrosion resistant material is composed of a first valve seat that can support the ball and seal the through-hole, and a second valve seat that has a substantially cylindrical shape surrounding the first valve seat and in which the space between a valve case and the second valve seat is sealed by an O-ring. Clearances d3 and d4 are formed between the first valve seat and the second valve seat, and a horizontal surface of a notched portion of the second valve seat is mounted on an upper surface of a flange portion of the first valve seat.

摘要： A reciprocating compressor includes a compressor cylinder defining a cylinder wall, a valve bore formed in the cylinder wall, and a compressor valve assembly arranged in the compressor cylinder. The compressor valve assembly includes a valve liner having a liner body and a liner flange disposed at an end of the liner body. The liner body is disposed in the valve bore. The liner flange is positioned in contact with the compressor cylinder. A valve seat is coupled to an inner surface of the liner body. The valve seat has a seating surface formed at an end of the valve seat. A compressor valve is positioned on the seating surface of the valve seat. A valve cage is positioned on the compressor valve. A valve cover is coupled to the valve cage to apply a bias force to retain the compressor valve on the seating surface of the valve seat.
