Abstract
The utility model relates to a sealing device of a compressor air valve, in particular to a valve plate of a piston type compressor air valve. The vale plate is formed by two ring-shaped valve plates, the joints of the two ring-shaped vale plates are provided with air channels, the two sides of the air channels are of sealing faces, a plurality of the air channels are provided, and are evenly distributed along circumference, and the air channel is arc-shaped. The valve plate changes the structures of a traditional single ring-shaped valve plate and an integrated reticular valve plate, two ring-shaped valve plates are combined to form a combined valve plate, the spring force matching is more reasonable, the friction face of the valve plate with a valve cover lug boss is small, the sealing performance is excellent, and the valve plate is more suitable for places which have dirt dielectric and large channels.
Description
Technical field
The utility model relates to the seal arrangement of compressor valve, specifically a kind of valve block of piston compressor air valve.
Background technique
Piston compressor is widely used in fields such as national defence, oil, chemical industry, metallurgy, whether it can move safely and reliably, the Rational structure and the performance that depend on air valve to a great extent, just because of this cause, people usually liken air valve to the heart of piston compressor.
Air valve is made up of valve seat, lift limiter, valve block and spring etc.Valve block can be divided into ring-shaped valve, netted valve block, strip valve block etc. by its structure, uses more with ring-shaped valve, netted valve block at present.
Shown in Fig. 1～3, the valve block of ring valve is simple annular, is sealing surface 1 between the interior external diameter.Each valve block all needs guiding, is generally finished by the boss on the lift limiter, and all be furnished with the spring of some below each ring-shaped valve.According to the characteristics of ring valve work, the ratio of adjacent each chain rate spring force (spring force on the unit area) will be controlled at 1.1＞F
i/ F
I+1＞1.02 (F
iBe the spring force of i ring-shaped valve, F
I+1Be the spring force of i+1 ring-shaped valve) in the scope.The advantage of ring-shaped valve is: ring-like simple, good seal is particularly suitable for the occasion that pressure is low, diameter is big, medium is dirty; Shortcoming is: the rubbing surface of valve block and valve seat is many, the valve seat construction complexity, and spring force is difficult for coupling, is difficult to reach all ring-shaped valves in the switching motion and opens and closes simultaneously, causes energy loss.
As shown in Figure 4, netted valve block is that a plurality of adjacent ring-shaped valves are linked into an integrated entity, and becomes whole valve block, has a plurality of air-flow paths 2 on the sealing surface 1 of centre, is netted; The following spring of also being furnished with some of valve block is particularly suitable for pressure height, occasion that diameter is little.The advantage of netted valve block is: valve block keying concertedness is good, and valve block is stressed evenly; Shortcoming is: the valve block complexity, and sealing is poor than ring-shaped valve, and any one damage all can cause whole valve block seal failure.
The model utility content
In order to solve the problem of above-mentioned existence, the purpose of this utility model is to provide a kind of valve block of taking into account the piston compressor air valve of ring-shaped valve and netted valve block advantage.
The purpose of this utility model is achieved through the following technical solutions:
The utility model is formed one by two ring-shaped valves, and the junction of two ring-shaped valves has air-flow path, and the both sides of air-flow path are sealing surface.
Wherein: described air-flow path is a plurality of, is uniformly distributed along the circumference; Air-flow path is an arc.
Advantage of the present utility model and good effect are:
The utility model has changed the structure of the netted valve block of traditional single ring-shaped valve and whole Zhang Yiti, two ring-shaped valves are combined into one, form knockdown valve block, the spring force coupling is more reasonable, valve block and valve gap boss rubbing surface are few, good seal performance, it is dirty to be particularly suitable for medium, the occasion that passage is big.Be specially:
1. when spring force mates, air valve per two is looked around work one ring calculate it, make each chain rate spring force be easy to rational Match than spring force.
2. it is roughly the same respectively to encircle the spring pre compressed magnitude, makes that respectively encircling the valve block keying reaches unanimity.
3. the guide ledges on the valve gap reduces one times, has reduced the valve gap amount of finish, has also reduced the friction of valve block and valve gap.
4. compare with ring-shaped valve, after the two ring combinations, valve group valve block quantity reduces, and makes that respectively to encircle concertedness higher.
5. compare with netted valve block, whole valve block resolved into several rings, better tightness.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 5, the utility model is formed one by two ring-shaped valves, and being designed to two rings is one group combination valve block in the form of a ring, and the junction of two ring-shaped valves has air-flow path 2, and the both sides of air-flow path 2 are sealing surface 1.Air-flow path 2 is an arc, is uniformly distributed with along the circumference a plurality of.
Shown in Fig. 6～7, for the matching used valve gap 3 of the utility model valve block, the one side that valve gap 3 is relative with valve seat is provided with a plurality of boss 4, be provided with deep gouge 5 between the adjacent lands 4, valve block is contained in the deep gouge 5, valve gap 3 is covered on valve seat, by the valve block seal valve seat again.Gas enters compressor through the air-flow path on the valve seat, the air-flow path on the valve block, the air-flow path on the valve gap successively.Adopt valve block of the present utility model and the valve gap supporting with it, only need three groups of valve blocks, compare with ring-shaped valve and to have reduced valve block quantity (needing six groups) as adopting ring-shaped valve, also reduce the friction (the C face is the rubbing surface of valve block and valve gap among Fig. 7) of valve block and valve gap simultaneously, and then reduced the valve gap amount of finish.
