Abstract
A shock-resistant tubular type one-way valve for tape guide, belongs to valve technology field.Comprise valve seat, compound gasket, spool combination, valve body, gland; Valve seat and valve body, be between gland with valve body and be threaded, and clip compound gasket; Spool combination comprises steel ball, cushion block, spring, briquetting; Valve seat there is circular arc valve; Valve interior surface is four arcs structure, is linear contact lay with steel ball.Advantage is: impact resisting vibrating, and with guiding device, can prevent valve element position from offseting, highly sensitive.
Description
Technical field
The utility model belongs to valve technology field.In particular to a kind of shock-resistant tubular type one-way valve of tape guide.Be mainly used to control media flow direction, be particularly useful for the high pressure pipe line that pressure change is larger, working pressure 0.3-25MPa.
Background technique
One-way valve is that one makes fluid can only one-way flow, and the device that cannot reflux, existing one-way valve, generally comprises valve seat, valve body and sliding valve core.Valve seat is fixedly connected with valve body, is connected with spring between sliding valve core and valve body, and this one-way valve has the following disadvantages: (1) is not shock-resistant, when outlet pressure is alternate load, spool is large to the impact of valve seat, spool and the prooving of valve seat fast, yielding, cause seal failure.(2) area of contact of sliding valve core and valve body is comparatively large, and when sliding valve core is slided, surface friction drag is comparatively large, and when pressure medium is less, cannot overcome the surface friction drag between sliding valve core and valve seat, make one-way valve clamping stagnation, sensitivity is low, and impact normally uses.
Summary of the invention
The purpose of this utility model is the shock-resistant tubular type one-way valve providing a kind of tape guide, solves spool large to the impact of valve seat, the problems such as the surface friction drag between sliding valve core and valve seat is large.
The utility model comprises valve seat, compound gasket, spool combination, valve body, gland.Valve seat and valve body, be between gland with valve body and be threaded, and clip compound gasket, play seal action; Spool combination comprises steel ball, cushion block, spring, briquetting.Cushion block is on the right side of steel ball, and spring is between cushion block and briquetting; Cushion block and briquetting nylon material, alleviate weight while proof strength, can reduce impact during closed check valve; Valve seat there is circular arc valve port, through Overheating Treatment, there is higher hardness, shock-resistant and wearing and tearing; Valve interior surface is four arcs structure, is linear contact lay with steel ball, and contact length is the 30%-45% of valve body inner circle girth, effectively can reduce the surface friction drag of spool and valve body, improves sensitivity, has guide function simultaneously, ensures steel ball centering.
The utility model has the advantage of:
1, one-way valve structures is simple, easy to assembly, is specially adapted to the evacuate air of high pressure pipe line, prevents water hammer.
2, impact resisting vibrating, and with guiding device, can prevent valve element position from offseting, highly sensitive.
3, adopt this structure to increase actual internal area, reduce valve resistance.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one-way valve.Wherein, valve seat 1, compound gasket 2, valve body 3, steel ball 4, cushion block 5, spring 6, briquetting 7, gland 8.
Fig. 2 is that the A of valve body is to sectional view.
Embodiment
Fig. 1-Fig. 2 is specific embodiment of the utility model.
Described model utility is provided with valve seat 1, compound gasket 2, spool combination, valve body 3, gland 8.Valve seat 1 and valve body 3, be between gland 8 with valve body 3 and be threaded, and clip compound gasket 2, play seal action; Spool combination comprises steel ball 4, cushion block 5, spring 6, briquetting 7.Cushion block 5 is on the right side of steel ball 4, and spring 6 is between cushion block 5 and briquetting 7; Cushion block 5 and briquetting 7 nylon material, alleviate weight while proof strength, can reduce impact during closed check valve; Valve seat 1 there is circular arc valve port, through Overheating Treatment, there is higher hardness, shock-resistant and wearing and tearing; Valve body 3 internal surface is four arcs structure, is linear contact lay with steel ball 4, and contact length is 40% of valve body 3 inner circle girth, effectively can reduce the surface friction drag of spool and valve body, improves sensitivity, has guide function simultaneously, ensures steel ball centering.
During use, fluid enters from valve seat 1, pushes steel ball 4 open, flows into briquetting 7, finally flow out along gland 8 by the guiding groove on valve body.When reverse fluid flow or valve seat 1 side liquid pressure are lower than 0.3MPa, steel ball 4 under spring force, gets back to valve seat 1, realizes cutting off fluid matasomatism.
