Description

A kind of compressor valve with buffer protection

Technical field

The utility model relates to compressor accessory technical fields, and in particular to a kind of compressor valve with buffer protection.

Background technique

Compressor valve generally comprises coaxially connected valve seat and valve deck, is provided with valve seat stomata on valve seat, on valve deck Be correspondingly arranged on and constitute the valve deck stomata that be connected to valve seat stomata, be additionally provided with valve block between valve seat and valve deck, the valve block and Compressed spring is provided between valve deck, and the valve block constitutes the covering to valve seat stomata under the action of compressed spring.Work When, gas enters from valve seat stomata, so that valve block is pushed to overcome the active force of compressed spring and open, after gas disappears, valve block It is re-closing off under the action of compressed spring, that is, constitutes the covering to valve seat stomata.In this switching process, valve block can be regular Collide with valve seat, and since existing valve block, valve seat are metal material, such structure setting is not only sealed Performance is poor, and regular collision also easilys lead to valve block and is damaged, so as to shorten the service life of air valve.Meanwhile when It when the gas instantaneous pressure entered in air valve is excessive, also results in valve block and collides with valve deck, it is impaired equally to easily lead to valve block.

Summary of the invention

In view of the deficiencies of the prior art, the utility model provides that a kind of sealing performance is more preferable and the compression with buffer protection Machine air valve.

To achieve the above object, the utility model provides a kind of compressor valve with buffer protection, including coaxially connects The valve seat and valve deck connect is provided with valve seat stomata on valve seat, is correspondingly arranged on valve deck and constitutes the valve deck being connected to valve seat stomata Stomata is additionally provided with valve block between valve seat and valve deck, compressed spring is provided between the valve block and valve deck, and the valve block exists The covering to valve seat stomata is constituted under the action of compressed spring, valve block is provided with rubber pad towards fitting on the end face of valve seat, and The radial both ends of rubber pad, which are additionally provided with, forms the elongated end being bonded with the inside and outside periphery of valve block respectively, wherein an elongated end End is connected with the bumper ring that section is sleeping U-shaped, and the bumper ring sticks on valve block towards on the end face of valve deck, another extension The end at end is correspondingly arranged on the locating ring being inserted into the bumper ring, and is additionally provided between the locating ring and bumper ring The location structure being mutually located, also correspondence offers the mounting hole passed through for compressed spring on the locating ring and bumper ring.

The beneficial effects of the utility model are: using the above structure, firstly, by being pasted on end face of the valve block towards valve seat Setting rubber pad is closed, the sealing performance of air valve not only can be effectively promoted, but also it is direct effectively to avoid valve block and valve seat from occurring Hard collision, thus to valve block formed buffer protection；Secondly, the rubber pad also has there are two elongated end, wherein one extends The end at end is connected with the bumper ring that section is sleeping U-shaped, and the bumper ring sticks on valve block towards on the end face of valve deck, another The end of elongated end is correspondingly arranged on the locating ring being inserted into the bumper ring, and also sets between the locating ring and bumper ring It is equipped with the location structure being mutually located, therefore not only rubber pad is fixed on valve block securely in this way, but also is slow by sleeping U-shaped Rush the buffer protection of circle, moreover it is possible to effectively valve block is avoided to collide with valve deck, so that further buffer protection is formed to valve block, And then extend the whole service life of air valve.Finally, corresponding open up passes through for compressed spring on the locating ring and bumper ring Mounting hole, moreover it is possible to convenient for the location and installation of compressed spring.

It includes mutual that the utility model, which can be further arranged to the location structure being equipped between the locating ring and bumper ring, The location hole and positioning column of grafting location fit are constituted, the location hole and positioning column are respectively set on locating ring and bumper ring. By the grafting location fit of location hole and positioning column, match so that solid and reliable positioning can be formed between locating ring and bumper ring It closes, so that rubber pad stronger can be securely fixed on valve block.

The utility model may further be provided as the valve block towards being also provided with annular spacing groove on the end face of valve deck, The annular convex rib that grafting limit cooperation is constituted with annular spacing groove is correspondingly arranged on bumper ring.Pass through annular convex rib and annular limit The grafting of position slot limits cooperation, fixes so that can form further limit between bumper ring and valve block, so that rubber pad It stronger can be securely fixed on valve block.
