Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of compressor valve.
Background technique
Air valve is mounted in the parts of control gaseous turnover on the compresser cylinder, and its performance directly influences the Economy and the reliability of compressor.The compressor valve structural type is various, in the big-and-middle-sized at home compressor, and the air valve that the critical piece that is most widely used is made up of valve seat, valve block, lift pad, buffer substrate tablet, spring, lift limiter etc.Valve seat, valve block, lift pad, buffer substrate tablet, lift limiter are linked in sequence successively on bolt, and spring one end is fixed on the lift limiter, and the other end withstands on the valve block back side, the valve block front is close to forms a sealing surface on the valve seat.Under the normality, air valve is in closed condition, and valve block is withstanding under the effect of spring on the sealing surface of valve seat; When the stream pressure that passes through on the valve seat during greater than the air pressure sum at the elastic force of spring and the valve block back side, the elastic force that valve block overcomes spring moves down, and valve seat and valve block are in the non-tight state, and gas circuit is got through.
In the actual compressor air valve working procedure, because it is inhomogeneous to flow through the air-flow of air valve, valve block is run-off the straight simultaneously in the process that rises or descend, edge sharp impacts at the surface of contact of tilting procedure middle valve plate and valve seat or lift limiter, cause three's edge section to be damaged easily, this situation is one of reason that causes the shortening of air valve operating life.In order to address this problem, some producers have designed as the disclosed a kind of compressor valve of Chinese patent (CN2766062Y), between valve block and lift limiter, added buffer substrate tablet, buffer substrate tablet no doubt can play certain buffer function to valve block, but buffer substrate tablet can't cushion the impact between valve block and the valve seat, and the effect of buffer substrate tablet buffering is more limited simultaneously.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist at existing technology, and a kind of simple in structure, the compressor valve that can effectively extenuate impact force is provided.
The purpose of this utility model can realize by following technical proposal: a kind of compressor valve; comprise superimposed successively valve seat, valve block, buffer substrate tablet and lift limiter; four are connected in series by a bolt that passes its center; it is characterized in that, apply one deck rubber-like protective layer one on the sealing surface of described valve seat.
The working principle of this structure is as follows: in the working procedure of air valve; when the air-flow that flows through inhomogeneous; valve block can tilt in the process that rises or descend simultaneously; violent collision takes place in the edge part branch of valve block and valve seat, lift limiter; owing to be coated with flexible protective layer one on the surface of contact of valve seat and valve block; the valve block collision can be cushioned on protective layer one, and impact force dies down, and valve block is extended working time.
In above-mentioned a kind of compressor valve, the interior edge face of described lift limiter is provided with flexible protective layer two.When air valve was opened, valve block moved downward, and protective layer two can weaken the collision of valve block edge and lift limiter interior edge face, prolonged both working life.
In above-mentioned a kind of compressor valve, be provided with buffer substrate tablet between described valve block and the lift limiter, described buffer substrate tablet is set on the above-mentioned bolt.Can reach the effect of multi-buffer after the increase buffer substrate tablet, improve the effect of protection.
In above-mentioned a kind of compressor valve, described protective layer one and protective layer two are made by plastic materials.Plastics are a kind of better elastic materials, can change the elasticity of plastics by add different additives in plastics, and the wear resistance of plastics and corrosion resistance are all relatively good.
In above-mentioned a kind of compressor valve, described plastic materials is PEEK.Can form a smooth homogeneous plane after the processing of PEEK coating, intensity under 260 ℃ of high temperature is greater than PTFE intensity at ambient temperature, plastic deformation and distortion that compression is caused have stronger resistivity, the PEEK coating has good acid resistance, alkali resistance, anti-hydrocarbon, salt tolerance and anti-steam performance, and its chemical resistance is better than many rare metals such as stainless steel and titanium.
In above-mentioned a kind of compressor valve, described protective layer one is circular, is distributed in the edge section of sealing surface of seat.Consider that the severe impact of valve block and valve seat mainly concentrates on the edge of valve seat,, protective layer made circular that only apply in the edge section of valve seat, Bao Hu effect also can reach like this in order to save the material of part.
In above-mentioned a kind of compressor valve, described protective layer two is circular, is distributed in the edge section of the interior edge face of lift limiter.
In above-mentioned a kind of compressor valve, described protective layer one and protective layer two pass through the mode of spraying respectively attached on valve seat and the lift limiter.Spraying operation manufacturing efficiency height is applicable to handwork and industrial automation production, and applied range mainly contains five metals, plastic cement, and family property, military project, fields such as boats and ships are that the most general volume is used a kind of application mode now, and the elasitic layer of spraying is relatively evenly with smooth.
Compared with prior art, this compressor valve is simple and clear, produces and uses all fairly simple; After spraying the PEEK coating on valve seat and the lift limiter, the impact stress of working procedure middle valve plate has been played good buffer function, prolonged working life; PEEK has good chemical property, has improved the antifouling of air valve and corrosion-resistant performance; Adopt the adhering mode of spraying as elasitic layer, the manufacturing efficiency height, the distribution of material of elasitic layer is more even.
