Abstract

The utility model provides a piston compressor pneumatic valve, has disk seat and lift limiter, through double -screw bolt and nut fixed joint, is equipped with the valve block between disk seat and the lift limiter between disk seat and the lift limiter, and the locating pin passes the valve block, and the valve block passes through locating pin and disk seat and lift limiter fixed connection, is equipped with the spring hole on the lift limiter, and downthehole the inlaying of spring is equipped with the spring, be equipped with the spring compressor between valve block and the spring, the bottom in spring hole is supported on the one end top of spring, and the other end of spring pushes up and supports the spring compressor, the diameter of spring compressor is greater than the external diameter of spring, and the spring compressor is pipe cap shape, and the tubulose position of its lower part inlays to be established in the spring hole, because of the valve block obtains effective protection of spring compressor, makes engineering plastics valve block running life increased substantially, full play use the advantage of plastics valve block pneumatic valve, both reduced the gas leakage, can prolong vulnerable part replacement cycle again, the also corresponding extension of life of pneumatic valve, compressor -running is stable, cost reduction.

Description

A kind of Compressor Valve

Technical field

This utility model relates to compressor field, particularly relates to a kind of Compressor Valve.

Background technology

Most piston compressor ring air flap structures are by valve seat, valve block, spring, lift The part compositions such as limiter, stud, nut, ring-shaped valve is annular lamina or the disjunctor of each ring separation Sheet, spring for valve withstands single or double valve block and to be close to valve seat at the effect lower disc of gas pressure difference close Front cover and seal gas, due to engineering plastics valve block, there is many obvious advantages at present, most Compressor producer is used, but the intensity of engineering plastics valve block and hardness are consistently lower than steel valve block, In real work, use this air valve after a period of time cannot be further continued for work, after testing with point Analysis, the sealing of air valve is jointly to promote valve block to be close to valve seat by gas force with spring force to complete, existing Having in technology, owing to spring for valve steel wire is relatively thin, its end must be through polishing, but its annulus area is still Less, the biggest to the ratio pressure (unit are pressure) of gas valve plate, this exceedes valve block intensity than pressure Time, then valve block is easily deformed inefficacy or damages, and meanwhile, it is jack-up all the time that structure must make spring Valve block, but spring end and valve block contact portion are irregular annular, As time goes on, Valve block at spring contact forms irregular annular groove, causes valve block deformation or fracture to make the sealing of air valve Losing efficacy, and ultimately resulted in compressor performance and decline, flow increases with the pressure loss, and power consumption increases, and And needing to be replaced as frequently as valve block, user's operating cost increases, and the economy of compressor is deteriorated.

Utility model content

This utility model provides a kind of Compressor Valve, it is therefore an objective to for solving in prior art Problem, it is provided that service life is long, and work stable, low cost, the piston of good seal performance Formula compressor valve.

The technical solution of the utility model is:

A kind of Compressor Valve, it is characterised in that: there is valve seat and lift limiter, valve Connect, between valve seat and lift limiter by stud and nut are fixing between seat and lift limiter Being provided with valve block, alignment pin passes valve block, and valve block is fixed with valve seat and lift limiter by alignment pin Connecting, lift limiter is provided with spring eye, is embedded with spring, described valve block and bullet in spring eye Spring compressor it is provided with between spring, the bottom of one end contact spring eye of spring, the other end contact of spring Spring compressor.

The diameter of described spring compressor is more than the external diameter of spring.

Described spring compressor is pipe cap shape, and the tubulose position of its underpart is embedded in spring eye.

Described spring compressor is stainless steel spring cap.

The beneficial effects of the utility model: because valve block obtains effective protection of spring compressor, make engineering Plastic valve plate service life is greatly improved, and has given full play to use the excellent of plastic valve plate air valve Point, both reduced gas leakage, the consumable accessory replacement cycle can be extended again, the service life of air valve also phase Should extend, compressor operating is stable, and cost reduces.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

A kind of Compressor Valve, has valve seat 1 and lift limit as shown in Figure 1 and Figure 2 Device 2, by stud 3 and the fixing connection of nut 4, valve seat between valve seat 1 and lift limiter 2 Being provided with valve block 5 between 1 and lift limiter 2, alignment pin 6 is through valve block 5, and valve block 5 is by fixed Position pin 6 is fixed be connected with valve seat 1 and lift limiter 2, and lift limiter 2 is provided with spring eye 7, it is embedded with spring 8 in spring eye 7, between described valve block 5 and spring 8, is provided with spring compressor 9, The bottom of one end contact spring eye 7 of spring 8, the other end contact spring compressor 9 of spring 8, institute Stating the diameter external diameter more than spring 8 of spring compressor 9, described spring compressor 9 is the pipe of stainless steel Hat, the tubulose position of its underpart is embedded in spring eye 7, and spring 8 gives valve by spring compressor 9 Sheet 5 applies pressure, thus compresses valve block 5, reduces the leakage of gas.

In use, the contact area between spring and valve block is increased by spring compressor so that it is ratio Pressure cannot be greater than the intensity of valve block, and spring compressor is designed to pipe cap form, and places the spring in wherein, Making spring form one with spring compressor, both open along with valve block simultaneously and move up and down, spring compressor Location be embedded in spring eye, by the tubulose position of its underpart, realizations, when for oil-free lubrication compression During machine, spring compressor material preferably selects rustless steel to make, and the design of spring compressor is enough in guarantee What under intensity, quality should be possible is light.
