Abstract
The invention relates to a compressor air valve which comprises a valve seat and a valve cover. The valve seat is connected with the valve cover through a bolt, the valve seat and the valve cover are fixed through a pin, a spring hole is formed in the valve cover, a spring is arranged in the spring hole, a spring cap is arranged at the top of the spring, the upper portion of the spring cap is connected with a valve sheet, and an air hole is formed in the upper portion of the valve sheet. The compressor air valve is good in air sealing performance, long in using time and convenient to manufacture.
Description
Technical field
The invention belongs to air valve field, be specifically related to a kind of compressor valve.
Background technique
Air valve is the vitals in Reciprocting piston compressor, is also one of flimsy parts.Its quality directly affects air displacement, power consumpiton and the maintainability of compressor, current compressor forward high speed future development, and one of key issue that restriction rotating speed improves is exactly air valve.Air valve is had to following requirement: drag losses is little.Air valve drag losses size is relevant with speed and the spring force size of air-flow.Gas speed is higher, and energy loss is larger; Spring force is excessive, and drag losses is also large, and its size is pressed the Rationality design of the air valve characteristics of motion and determined.Air valve closes in time, rapidly, air tight while closing, to improve the efficiency of machine, extend using period.But spring for valve hole is in use often easily stopped up by dust, cause tightness variation; Service time is long, also can cause valve seat and valve gap displacement, affects the tightness of air valve.
Summary of the invention
For solving the above-mentioned shortcoming of existing compressor valve, the invention provides a kind of compressor valve, improved sealability and the wear resistance of valve.
The present invention is achieved through the following technical solutions:
A compressor valve, comprises valve seat, valve gap, and valve seat and valve gap are bolted, and be fixed by pin, valve gap is provided with spring eye, is provided with spring in spring eye, spring top is provided with spring compressor, and spring compressor top is connected with valve block, and valve block top is provided with pore.
Described valve block is PEEK plastic valve plate.
Described spring compressor is provided with micropore.
The axial direction of described spring eye and valve seat is provided with locating stud.
Beneficial effect of the present invention: the present invention by arranging spring compressor on spring, in use, can be by the elastic force Transmit evenly of spring to valve block, make valve block stressed evenly, reduced the friction to a certain side, improved the service time of valve block, and spring compressor can prevent that in using process, dust enters spring eye deposition effectively, cause spring force to decline, reduce the sealing of air valve, valve block of the present invention is PEEK plastic valve plate, wear resistance improves greatly, extended the working life of valve block, can effectively improve the lift of valve block simultaneously, improved the efficiency of valve.
Accompanying drawing explanation
Fig. 1 is compressor valve sectional drawing.
