Abstract
The invention discloses a kind of anti-seal circle deformation type check valve, including tubular valve body, the ring-shaped valve seats being formed in valve body, it is arranged on the sealing ring of valve seat bottom, and can be relatively described the spool that moves up and down of valve body, described spool includes that upper end is formed with the valve rod sealing inclined-plane to be in close contact with described sealing ring, and fixes the positioning tube being connected and may pass through described valve seat with described valve rod upper surface.The check valve of the present invention, it is formed with positioning tube on the valve rod top of spool, when valve rod moves up and down, positioning tube can be always situated in sealing ring, can effectively prevent the deformation of sealing ring, simultaneously, because the diameter of positioning tube is less than valve seat, i.e. sealing ring keeps certain interval with positioning tube when indeformable, can't constitute impact to it, when sealing ring is inevitably deformed upon by high temperature etc., it can effectively be supported by positioning tube, it is made to keep basic rounded form, it is ensured that basic sealing effectiveness.
Description
Technical field
The present invention relates to Machining Technology field, particularly relate to a kind of anti-seal circle deformation type check valve.
Background technology
There is a lot of check valves in order to the break-make of oil circuit control or switching, check valve in the fats and oils processing such as fat of Oromaius norvaehollandeae machinery
In sealing ring can be positioned at valve seat bottom, washing away of long-term high temperature change and grease, can cause sealing valve deformation, then can
Cause seal failure, if sealing valve to be changed, need to stop work whole system, just can change after cooling, cause producing
Inefficiency.
Content of the invention
It is an object of the invention to for technological deficiency present in prior art, and a kind of anti-seal circle deformation type list is provided
To valve.
By realizing that the purpose of the present invention be the technical scheme is that
A kind of anti-seal circle deformation type check valve, including tubular valve body, the ring-shaped valve seats being formed in valve body, is arranged on valve
The sealing ring of seat bottom, and can be relatively described the spool that moves up and down of valve body, it is close that described spool includes that upper end is formed with
The valve rod to be in close contact with described sealing ring for the envelope inclined-plane, and fixing with described valve rod upper surface be connected and may pass through institute
The positioning tube of the valve seat stated, is provided with through hole bottom described positioning tube.
Described positioning tube is welded to connect with described valve rod.
Described positioning tube is identical with described valve rod material.
Compared with prior art, the invention has the beneficial effects as follows:
The check valve of the present invention, is formed with positioning tube on the valve rod top of spool, when valve rod moves up and down, and positioning tube meeting
Always situated in sealing ring, can effectively prevent the deformation of sealing ring, because the diameter of positioning tube is less than valve seat, i.e. seal meanwhile
Circle keeps certain interval with positioning tube when indeformable, can't constitute impact to it, when sealing ring can not by high temperature etc.
When deforming upon with avoiding, it can effectively be supported by positioning tube so that it is keeps basic rounded form, it is ensured that basic is close
Envelope effect, can effectively extend its effective storage life, it is to avoid unexpected leakage occurs, and utilizes routine maintenance can realize check valve
Maintenance and replacing.
Brief description
Fig. 1 show the structural representation of the anti-seal circle deformation type check valve of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.It should be appreciated that described herein
Specific embodiment only in order to explain the present invention, be not intended to limit the present invention.
As it is shown in figure 1, the anti-seal circle deformation type check valve of the present invention, including tubular valve body 1, the ring being formed in valve body
Shape valve seat 2, is arranged on the sealing ring 3 of valve seat bottom, and can be relatively described the spool 4 that moves up and down of valve body, described valve
Core includes that upper end is formed with the valve rod sealing inclined-plane to be in close contact with described sealing ring, and with described valve rod upper surface
The fixing positioning tube 5 connecting and may pass through described valve seat, is provided with through hole 6, wherein, institute in described positioning tube bottom part ring week
The height of the positioning tube stated is greater than the stroke of check valve to play the effect of the inner support to sealing ring in whole course of action
Really.
Wherein it is desired to explanation, be herein with fluid flow into direction be upper, fluid flow out direction be under, i.e.
Fluid flows into from upper end, and lower end is flowed out, and spool upwards moves and closes check valve, and when spool moves downward, check valve is opened,
Fluid passes through.
The check valve of the present invention, is formed with positioning tube on the valve rod top of spool, when valve rod moves up and down, and positioning tube meeting
In the middle part of sealing ring, can effectively prevent the deformation of sealing ring, meanwhile, because the diameter of positioning tube is less than valve seat, i.e. close
Seal keeps certain interval with positioning tube when indeformable, can't constitute impact to it, when sealing ring by high temperature etc. no
When can deform upon with avoiding, positioning tube can carry out effective inner support to it so that it is keeps basic rounded form, it is ensured that basic
Sealing effectiveness, can effectively extend its effective storage life, it is to avoid unexpected leakage occurs, utilize routine maintenance can realize unidirectional
The maintenance of valve and replacing.
Preferably, described positioning tube is welded to connect with described valve rod, meanwhile, and described positioning tube and described valve rod
Material is identical, and the thickness of described positioning tube and height require with satisfied use.
The above is only the preferred embodiment of the present invention, it is noted that for the common skill of the art
For art personnel, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications
Also should be regarded as protection scope of the present invention.
