Abstract
The utility model discloses a compressor air valve, belonging to the field of the compressor. The compressor air valve comprises a valve base, a piston rod and a valve sheet, and further comprises a guide ring and a buffer sheet, wherein a guide ring is sleeved on the piston rod so as to be fixed; the buffer sheet is superposed with the valve sheet, and fixedly connected with the guide ring; and a spring is further arranged between the buffer sheet and the valve base. According to the utility model, the valve sheet has a long service life, will not swing along the radial direction due to the influence of the air pressure in a reciprocating motion process; moreover, the compressor air valve further has the advantage of a simple structure.
Description
Technical field
The utility model relates to a kind of compressor valve.
Background technique
At present, air valve is an individual assembly the most key in the reciprocal compressor, and the reliability of compressor operating and Economy are all closely bound up with the air valve design, at present main air valve or the air valve that adopts on the compressor.The air valve assembly comprises valve seat, limiter and the valve block between the two; The center of valve seat and limiter is equipped with through hole; The two utilizes said through hole bolt to connect; Through hole is other to be provided with locating stud, and the end face of through hole protrudes from the said limiter body mating face relative with valve seat, and two wise man's the discrepancy in elevation is the range of permission.On the mating face of limiter body, also be not equipped with a plurality of annular grooves with one heart, be not equipped with the hole at the bottom of the annular groove, the spring that the installation and control valve block opens and closes in the hole, annular valve block is positioned at annular groove, and the degree of depth of annular groove equals throttle slice thickness.Throttle slice thickness is greater than people's lift, and therefore, valve block can be by annular groove wall guiding, and annular groove plays buffer function in the valve block opening process, can be so that air valve reduce the receptance of operating mode, thus improve air valve working life.Not enough below the air valve of existing structure and limiter thereof exist: when lift is big, or after the valve block wearing and tearing, when throttle slice thickness during smaller or equal to lift, valve block just might break away from annular groove and unrestricted motion in air valve, air valve was lost efficacy or damages, and reliability is lower.
Occurred subsequently as the applying date be on July 5th, 2010; Application number is 201020247559.1 patented technology scheme; This technological scheme is that mating face is provided with boss, has played the guiding length of extension valve block, and on certain Chengdu, has improved the reliability of valve block.
But technique scheme does not have radical change to the working life and the valve block problem of jolting in the course of the work of valve block.
The model utility content
The utility model provides a kind of valve block long service life, and valve block can radially not swung because of the influence of air pressure in the to-and-fro motion process, and the utility model also has advantage of simple structure.
For realizing above-mentioned technical purpose, the technological scheme of the utility model is following:
A kind of compressor valve comprises valve seat, piston rod and valve block, also comprises guide ring and buffer substrate tablet, and guide ring is socketed on the piston rod fixing, the overlapping setting of buffer substrate tablet and valve block, and be fixedly connected with guide ring, also be provided with spring between buffer substrate tablet and the valve seat.
Also be provided with the gap between said guide ring of the utility model and the valve block.
All have the hole on said buffer substrate tablet of the utility model and the valve block, hole and the hole on the valve block on the said buffer substrate tablet are relative in twos.
Hole on said buffer substrate tablet of the utility model and the valve block radially distributes.
Because adopt technique scheme, the beneficial effect of the utility model is following:
1, owing to be provided with guide ring, guide ring is fixed together valve block and piston rod, has prevented valve block effectively in to-and-fro motion, receives effects of air pressure and radially skew or swing;
2, increase buffer substrate tablet, consumed the potential energy of valve block effectively, and then reduced the impact of valve seat, prolonged the life-span of valve block valve block in working procedure;
3, also be provided with the gap between guide ring and the valve block, guaranteed that valve block can not swing;
4, all have the hole on buffer substrate tablet and the valve block, make valve block in compression process, can discharge gas, improved the working efficiency of compressor.
