Abstract
The utility model discloses a kind of high-pressure fluid check valve, including valve element, seal, valve body, spring and triangle nut；The valve body two ends are respectively arranged with fluid intake and fluid issuing；The seal is installed on valve element, and the seal outer end is fitted with fluid issuing inner face；The valve element is extended to after fluid intake by fluid issuing and installed with triangle nut, and the spring is set in outside valve element and top pressure is distinguished between body cavity wall and triangle nut in two ends.High-pressure fluid check valve of the present utility model, valve element is acted on spring force, and spool end is equipped with seal, fitted with valve body end face, air-tight state is formed, when pressure fluid inlet is more than outlet pressure, pressure forces spring-compressed, and valve element is moved to the port of export, and valve is opened, conversely, fluid is closed, pressure is bigger, more close, fluid countercurrent current and the design of external pipe thread will not be caused in fluid line because of reverse pressure difference so that valve body is compact, it is easy to integrated installation.
Description
Technical field
The utility model is related to a kind of high-pressure fluid check valve, belongs to check valve technical field.
Background technology
Check valve, also known as check-valves or non-return valve, are that fluid can only flow along water inlet, delivery port medium can not but flow back
Device, for prevented in hydraulic system oil stream reverse flow, the bright disclosure of Chinese patent of Application No. 201110328785.1
A kind of check valve, including valve body, piston and pressure cap, the piston are located at the inner chamber of valve body, one end of the valve body be provided with into
Gas port, one end of the pressure cap is provided with gas outlet, and the valve body can adjust the adjustment knot of check valve height with being additionally provided with pressure cap
Structure, the check valve can guarantee that normal mounting between two pipelines in the range of certain length and can reduce material cost and peace
Dress up this；But existing high-pressure fluid check valve is easily in fluid line because reverse pressure difference causes fluid countercurrent current, and causing can
It is poor by property, and existing high-pressure fluid check valve volume is larger so that use environment is restricted and is not easy to integrated installation.
Therefore, for original high-pressure fluid check valve easily in fluid line because reverse pressure difference causes fluid countercurrent current, cause reliable
Property is poor, and existing high-pressure fluid check valve volume is larger so that use environment is restricted and is difficult integration problem devises
A kind of new high-pressure fluid check valve.
Utility model content
To solve the above problems, the utility model proposes a kind of high-pressure fluid check valve, solve in fluid line because
The problem of reverse pressure difference causes fluid countercurrent current and the design of external pipe thread so that valve body is compact, it is easy to integrated installation.
High-pressure fluid check valve of the present utility model, including valve element, seal, valve body, spring and triangle nut；The valve
Body two ends are respectively arranged with fluid intake and fluid issuing；The seal is installed on valve element, the seal outer end with
Fluid issuing inner face is fitted；The valve element by fluid issuing extend to after fluid intake with triangle nut install, the spring housing
It is located at outside valve element and top pressure is distinguished between body cavity wall and triangle nut in two ends.
It is helicitic texture as preferred embodiment, outside the valve body.
Further, the valve element its away from triangle nut one end be pyramidal structure；The fluid issuing be and valve element one
Hold the conical cavity coordinated；Its inner end of the valve element is the helicitic texture coordinated with triangle nut.
Further, the seal is annular or pyramidal structure.
The utility model compared with prior art, valve element is acted on spring force, and spool end is equipped with seal,
Fitted with valve body end face, form air-tight state, when pressure fluid inlet is more than outlet pressure, pressure forces spring-compressed, valve element
Moved to the port of export, valve is opened, conversely, fluid is closed, pressure is bigger, more closes, will not be because reverse in fluid line
Pressure difference causes fluid countercurrent current and the design of external pipe thread so that valve body is compact, it is easy to integrated installation.
Brief description of the drawings
Fig. 1 is closure state schematic diagram of the present utility model.
Fig. 2 is opening schematic diagram of the present utility model.
Each part is labeled as in accompanying drawing：1- valve elements, 2- seals, 3- valve bodies, 4- springs, 5- triangle nuts, 6- fluids enter
Mouthful, 7- fluid issuings.
Embodiment
As depicted in figs. 1 and 2, high-pressure fluid check valve of the present utility model, high-pressure fluid check valve of the present utility model,
Including valve element 1, seal 2, valve body 3, spring 4 and triangle nut 5；The two ends of valve body 3 are respectively arranged with fluid intake 6 and stream
Body outlet 7；The seal 2 is installed on valve element 1, and the outer end of seal 2 is fitted with the inner face of fluid issuing 7；The valve
Core 1 is extended to after fluid intake 7 by fluid issuing 6 and installed with triangle nut 5, and the spring 4 is set in the outside of valve element 1 and two ends
Top pressure is between the internal chamber wall of valve body 3 and triangle nut 5 respectively.
The outside of valve body 3 is helicitic texture.
The valve element 1 its away from the one end of triangle nut 5 be pyramidal structure；The fluid issuing 7 be and the one end fits of valve element 1
Conical cavity；Described its inner end of valve element 1 is the helicitic texture coordinated with triangle nut 5.
The seal 2 is annular or pyramidal structure.
High-pressure fluid check valve of the present utility model, valve element is acted on spring force, and spool end is equipped with seal,
Fitted with valve body end face, form air-tight state, when pressure fluid inlet is more than outlet pressure, pressure forces spring-compressed, valve element
Moved to the port of export, valve is opened, conversely, fluid is closed, pressure is bigger, more closes, will not be because reverse in fluid line
Pressure difference causes fluid countercurrent current and the design of external pipe thread so that valve body is compact, it is easy to integrated installation.
Above-described embodiment, is only better embodiment of the present utility model, therefore all according to the utility model patent claim
The equivalent change or modification that described construction, feature and principle is done, is included in the utility model patent claim.
