fig. 3 is a top view of the reciprocating compressor air valve with low resistance anti-sticking function of the present invention.

In the figure: the valve comprises a valve body 1, a valve cover 2, a first annular clamping groove 3, a second annular clamping groove 4, a third annular clamping groove 5, a first air port 6, a second air port 7, a third air port 8, an annular clamping opening 9, a sealing ring 10, a sealing ring 11, an expansion link 12, a spring 13, a through hole 14, a stepped hole 15, a bolt 16, a nut 17 and a gasket 18.

Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.

As shown in fig. 1-3, the reciprocating compressor air valve with low resistance and anti-sticking function comprises a valve body 1, the valve body 1 is connected with a valve cover 2 through a fixing mechanism, a first ring-shaped clamping groove 3, a second ring-shaped clamping groove 4 and a third ring-shaped clamping groove 5 are sequentially arranged along the circumferential direction of the bottom surface of the valve body 1, a first air port 6, a second air port 7 and a third air port 8 are sequentially arranged along the circumferential direction of the top surface of the valve body 1 and the circumferential direction of the bottom surface of the valve cover 2, ring-shaped bayonets 9 are respectively arranged along the bottom surfaces of the first ring-shaped clamping groove 3, the second ring-shaped clamping groove 4 and the third ring-shaped clamping groove 5, sealing rings 10 are respectively arranged at two sides of the bottom of each ring-shaped bayonet 9, a sealing ring 11 positioned below the sealing ring 10 is respectively clamped in each ring-shaped bayonet 9, and every telescopic link 12 surface all is equipped with spring 13, above-mentioned pneumatic valve is when using, during the pneumatic valve pressure release, first ring groove 3, sealing ring 11 on the annular bayonet 9 in second ring groove 4 and the third ring groove 5 can downstream, open first gas port 6, second gas port 7 and third gas port 8 lose heart, and sealing ring 11's width is less than annular bayonet 9's width, so can not produce frictional force with annular bayonet 9 inner wall during the motion of sealing ring 11, from having exempted from the loss of pressure that causes because of frictional force, this pneumatic valve also need not oil and reduces the friction in addition, thereby 11 outer wall of sealing ring glues the phenomenon also can not appear.
