Journey retainer apertures, lift stopper are provided with each lift stopper hole, the lift stopper includes lift passage, institute
The one end for stating lift passage towards passage is provided with valve block, and limited post, the limited post and valve block are provided with lift passage
Between be provided with spring, the both ends of the spring contradict respectively press against valve block and limited post, in the passage inwall is provided with
Screw thread, the limited post are provided with external screw thread, and the limited post is threaded in lift passage.
One end that the limited post is located at outside lift passage is provided with hole of caving in.
The hole of caving in is arranged to that square caves in hole or regular hexagon caves in hole.
Lubricating oil is placed with the lift passage, one end and the valve block of the spring are fixed, and the other end is free end, and institute
The aperture of circle is less than the aperture of lift passage where stating spring.
The spring and valve block are detachable connection, and the side of the valve block towards spring is provided with junction button.
The junction button selects the semicircle Plastic fastener to be arched upward towards spring, and the junction button is located at valve block close to margin location
Put, one end of spring is inserted in limit buckle.
The valve seat is rounded, and the valve seat offers several passages, and several passages surround valve seat center circle
Week is uniformly distributed, and each passage is provided with a lift stopper.
The present invention operation principle be：
The air valve that the present invention is used for the equipment such as compressor uses, when air stream enter in compressor from valve seat side, it is necessary to through
Cross lift stopper, the air stream pressure certain to lift stopper, spring is compressed, valve block towards spring move, valve block with
Temporary air communication channel is formed between valve seat, air is entered in compressor.
After a period of time, spring can be tired, it is easier to by air stream compression, and by restoring force after compression
Die down, cause the drafting efficiency of air valve out of hand, sealing property reduces, and influences using effect.The present invention is according to the tired of spring
Labor degree, limited post is suitably tightened into a certain distance towards valve block, it is ensured that the power that spring is needed by compression with it is original
Unanimously, and after air stream enters, valve block and valve base sealing can rapidly be allowed in time.After the elasticity of spring loses serious, directly
Limited post is screwed down, the spring more renewed, realize that air valve recovers good performance again.
The beneficial effects of the invention are as follows：
The present invention, limited post can move up and down position in lift passage, will be spacing when the elasticity of spring has certain decrease
Post makes up the elasticity of spring decrease towards certain distance is screwed into lift passage, will be spacing when the elasticity of spring loses serious
Post is unloaded down, the spring more renewed, is realized that air valve can reuse, is avoided replacing from wasting raw material, improves the service efficiency of air valve.
