Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of compressor valve.
Background technique
Air valve is mounted in parts compresser cylinder controlling gas turnover, and its performance directly affects Economy and the reliability of compressor.Compressor air valve structure pattern is various, at home in big-and-middle-sized compressor, and the ring valve be made up of valve seat, ring-shaped valve, spring, lift limiter etc. be most widely used.The valve block of ring valve is arranged between valve seat and lift limiter, valve seat and lift limiter are located in being bolted together and valve seat and lift limiter offering the air-flow path of several ring-types of its center by one, each air-flow path correspondence on valve seat arranges a ring-shaped valve coordinated with it, and air-flow path is closed by the opening making ring-shaped valve can be fitted in air-flow path.When stream pressure is greater than spring force, ring-shaped valve is opened, and air-flow flows through through air-flow path, and when stream pressure is less than spring force, the opening plaster of ring-shaped valve and air-flow path merges to be formed and seals.The main technique requirements of compressor valve is that gas flows through that the drag losses of air valve is little, air valve will be grown working life, air valve is formed clearance volume is little, air valve has good sealing when closing.
As a kind of compressor valve [application number: 201020300295.1 proposed before claimant; Authorization Notice No.: CN 201818472 U]; comprise valve seat superimposed successively, valve block, buffer substrate tablet and lift limiter; four are connected in series by a bolt passing its center; the sealing surface of described valve seat applies one deck and have flexible protective layer one, the interior edge face of described lift limiter is provided with flexible protective layer two.
When above-mentioned compressor valve uses, when air pressure is less than spring force, valve block to be pressed on protective layer one and under the action of the spring by valve base sealing; When air pressure is greater than spring force, valve block moves down and offsets with protective layer two.By arranging protective layer one and protective layer two, valve block collision can be cushioned on the protection layer, and impact force dies down.Such protective layer just effectively protects valve seat, valve block and lift limiter, makes the longer service life of three.But there is a problem in above-mentioned compressor valve: protective layer one and protective layer two are respectively by being coated on valve seat and lift limiter; due in use; the impact forces of valve block to protective layer one and protective layer two is comparatively large, easily causes sag of protecting coating when impacting with high pressure.
Summary of the invention
The object of the invention is to there are the problems referred to above for existing technology, propose a kind of compressor valve of long service life.
Object of the present invention realizes by following technical proposal: a kind of compressor valve, comprise the valve seat set gradually from top to bottom, valve block with lift limiter and three be connected by a bolt, described valve seat is provided with some inlet holes, described valve block is provided with the vent one staggered with inlet hole, it is characterized in that, the interior edge face of described valve seat is provided with the first plastic spacer, described lift limiter the inner is provided with and makes valve block be pressed on spring on the first described plastic spacer, the concave-convex type linkage structure making both be connected is provided with between the side of the first described plastic spacer and valve seat, the corresponding through hole one being provided with some with described inlet hole and communicating on the first described plastic spacer, several through holes one all stagger with described vent, the first described plastic spacer opposite side is provided with some grooves on its surface of contact contacted with valve block.
