Detailed Description

In order to make the technical solutions of the present invention better understood and make the above features, objects, and advantages of the present invention more comprehensible, the present invention is further described with reference to the following examples. The examples are intended to illustrate the invention only and are not intended to limit the scope of the invention.

As shown in fig. 1, the present invention includes: the air valve 2 is tightly attached to the inner wall of the cylinder barrel 1 and sequentially comprises a valve rod sealing ring 201, an air valve core 202 and a valve seat 203 from top to bottom, an air valve hole 3 is formed in the air valve 2, a cushion pad 4 is arranged at the bottom of the air valve, and the cushion pad 4 is arc-shaped and is tightly attached to the cylinder barrel 1; the bottom of the cylinder barrel 1 is provided with a retainer ring 7

And the top of the retainer ring 7 is provided with an arc-shaped groove 8, and the arc-shaped groove 8 is consistent with the cross section of the cushion pad 4.

In the present embodiment, a seal ring 6 is preferably mounted on the top of the cylinder tube 1.

In this embodiment, it is preferable that the stem 5 is attached to the stem packing 201, and the stem 5 is extended to the outside of the cylinder 1 through the packing 6.

In this embodiment, it is preferred that the depth of the arcuate groove 8 is less than the height of the cushioning pad 4.

In the present embodiment, the cushion pad 4 is preferably made of rubber.

In the present embodiment, it is preferable that the gas hole 9 is provided in the middle of the retainer 7.

In this embodiment, the bottom of the cylinder 1 is preferably provided with a plug 10.

In use, the valve rod pushes down, and ventilative valve opening plays the effect of breathing freely, and when ventilative valve moved down, bottom blotter and arc recess contact played the cushioning effect, avoided the damage that traditional disk seat and retaining ring long-term collision caused.

The above-described embodiments are merely illustrative of the principles and utilities of the present patent application and are not intended to limit the present patent application. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of this patent application. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical concepts disclosed in the present application shall be covered by the claims of this patent application.
