Abstract
Special type gas compressor pneumatic valve relates to the piston natural gas compressor, can be applied to natural gas compression processing field, includes disk seat, lift limiter, valve block, valve gap, spring, and at one side of disk seat connecting screw rod, the valve gap cover is put and is locked on the screw rod and through the nut, and the quantity of lift limiter is one and for annular, the lift limiter cover is put on the screw rod, the quantity of valve block be one and for the annular, the valve block cover is put on the lift limiter, valve block and lift limiter all set up between disk seat and valve gap, the valve gap sets up four spring grooves towards one side of valve block along the circumferencial direction, and the spring has four, and four spring settings are at corresponding spring inslot, and the one end of every spring is all to tight valve block, valve gap, valve block, disk seat pass through the locating pin and connect. The utility model has the characteristics of it is following: 1, extension pneumatic valve life reduces the device structure number, 2, be convenient for pneumatic valve routine maintenance maintenance is rationally improved the pneumatic valve structure, 3, reduce worker's intensity of labour.
Description
Technical field
The utility model relates to piston-type natural gas compressor, can be applicable to natural gas compressing manufacture field.
Background technique
Natural gas compressor in use, spring for valve lost efficacy, lift limiter is damaged, valve block ruptures and distortion, sealing surface of seat occur that wearing and tearing in various degree cause air valve to miss and damage, affect the working efficiency of natural gas compressor, more renew air valve not only cost occupy Gao Bu little, change frequently and keep in repair air valve, increase the labor intensity of teams and groups, have a strong impact on normal production, decrease the output of rock gas and light oil simultaneously.
Use the unfavorable factor that existing air valve exists:
1) valve lift limiter wearing and tearing, uniform 8 lift limiters on the Internal and external cycle of Primordial Qi valve valve gap, in using process, the surface of contact of lift limiter and valve block, spring comparatively greatly, the corner of colliding is more, serious wear.
2) spring failure, uniform 8 springs of Internal and external cycle of Primordial Qi valve valve gap, the thickness up and down of spring is consistent, the easy landing of spring when mounted, be inconvenient to install, lift limiter wearing and tearing rear spring also deviate from the position of design, and the stressed of spring changes, cause spring fracture and elasticity to change, the probability that spring occurs to lose efficacy is larger.
3) valve block fracture and distortion, because valve block is double valve sheet, lift limiter wearing and tearing and spring failure after, cause that valve block is crooked, clamping stagnation, cause the change of valve block operating mode, valve block unbalance stress, open, close and impact change greatly, easily make valve block cause deformation and fracture at short notice.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of special gas compressor valve of long service life.
The purpose of this utility model is achieved in that special gas compressor valve, comprise valve seat, lift limiter, valve block, valve gap, spring, at the side connecting screw rod of valve seat, valve gap to be nested with on screw rod and to be locked by nut, the quantity of described lift limiter is one and is annular, and lift limiter is nested with on screw rod; The quantity of described valve block is one and is annular, and valve block is nested with on lift limiter, and valve block and lift limiter are all arranged between valve seat and valve gap; Described valve gap along the circumferential direction arranges four spring grooves towards the side of valve block, and described spring has four, and four springs are arranged in corresponding spring groove, and one end of every root spring all pushes against valve block; Described valve gap, valve block, valve seat are connected by locating stud.
The utility model, by changing the shape of lift limiter, makes an annular limiter into 8 lift limiters being uniformly distributed surrounding of Primordial Qi valve, and the screw rod being enclosed within valve seat plays restriction, and the limiter after improvement decreases area of contact.Reduce the number of spring and change the shape of spring, after improving, air valve becomes 4 springs by 8 springs, decreases wearing and tearing, serves the effect of the gentle valve of protection valve block.The structure of valve block before changing, double valve sheet becomes single valve sheet, guarantees that air valve can ensure self movement locus after partial spring lost efficacy, and reduces double valve sheet because the asynchronous wearing and tearing that cause of motion and fracture simultaneously.
The utility model has following characteristics:
1, extend air valve working life, reduce device maintenance number of times;
2, rational modification is carried out to air valve structure, be convenient to air valve daily maintenance;
3, the labor intensity of worker is reduced.
As improvement of the present utility model, the thickness of described annular lift limiter is greater than the thickness of annular valve block.
In order to prevent spring landing when mounted, one end diameter that every root spring contacts with valve block is less than one end diameter contacted with valve gap.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
As shown in Figure 1, special gas compressor valve, comprise valve seat 1, at the side connecting screw rod 7 of valve seat 1, screw rod 7 is nested with one and for annular lift limiter 2, lift limiter 2 is nested with one and for annular valve block 3, the thickness of annular lift limiter 2 is greater than the thickness of annular valve block 3, screw rod 7 is nested with valve gap 4 and is locked by nut 8, valve gap 4, valve block 3, valve seat 1 are connected by locating stud 9.Valve block 3 and lift limiter 2 are all arranged between valve seat 1 and valve gap 4, valve gap 4 along the circumferential direction arranges four spring grooves 5 towards the side of valve block 3, a spring 6 is all set in four spring grooves 5, one end of every root spring 6 all pushes against valve block 3, and one end diameter that every root spring 6 contacts with valve block 3 is less than one end diameter contacted with valve gap 4.
