Detailed Description

The following description of the embodiments refers to the accompanying drawings, which are included to illustrate specific embodiments in which the utility model may be practiced.

As shown in fig. 1, fig. 2 and fig. 3, the present embodiment discloses a compressor exhaust check valve, which includes a valve casing 1, a valve body 2, a valve core 3 and an elastic body 4, the valve casing 1 has an exhaust port 11, the outer surface of the valve casing 1 has a support surface 12, the support surface 12 continuously and uninterruptedly surrounds the exhaust port 11, the valve body 2 is connected to the valve casing 1, the valve core 3 and the elastic body 4 are both disposed in the valve body 2, two ends of the elastic body 4 respectively support against the valve body 2 and the valve core 3 and apply an acting force close to the valve casing 1 to the valve core 3, one side of the valve core 3 facing the valve casing 1 has a contact plane 31, and the contact plane 31 is sealed and supported against the support surface 12 and is used for sealing the exhaust port 11.

The valve core 3 contacts and is sealed and abutted to the abutting surface 12 of the valve casing 1 through the contact plane 31, so that a plane sealing mode is achieved, and the sealing effect between the valve casing 1 and the valve core 3 is effectively enhanced. Simultaneously, apply the effort that is close to valve casing 1 to case 3 through elastomer 4 for case 3 will closely support and lean on in valve casing 1, realize that contact plane 31 supports with supporting and lean on face 12 and closely laminate and support and lean on, further improved the sealed effect between valve casing 1 and the case 3, reach compressor exhaust check valve's the effect of preventing leaking, improved compressor exhaust check valve's safety and stability nature greatly. Meanwhile, the structure is simple, and the processing and the manufacturing are convenient.

In this embodiment, when the outlet side of valve casing 1 reaches certain pressure, the leakage quantity of compressor exhaust check valve need be less than a fixed value, and the structure that this embodiment adopted the plane seal mode just to design in order to satisfy this fixed value to effectively avoided compressor exhaust check valve to take place reverse leakage phenomenon, improved compressor exhaust check valve's safety and stability greatly.

One side of the valve core 3 facing the elastic body 4 is provided with an inward concave limiting groove 32, and the elastic body 4 is embedded in the limiting groove 32. The limiting groove 32 has the function of limiting the elastic body 4, effectively avoids the phenomenon of offset and dislocation of the elastic body 4 in the use process, ensures the surface contact between the contact plane 31 and the abutting surface 12, and further ensures the sealing effect. Meanwhile, the structure is simple, and the processing and the manufacturing are convenient.
