Description
Technical field
The present invention relates to a kind of anti-leakage valve.
Background technology
Direct Travel cage valve has switching mode and adjustment type etc., and the closing of valve at present is mainly contacted by valve element with valve seat
After sealing surface (line) completely attaches to afterwards, reach closing purpose with the passage after valve before stop valve, due to valve element and the frequency of valve seat
It is numerous to be contacting and separating, easily cause contact surface abrasion, so as to leak, can also trigger security incident when serious, therefore generally
Sealing ring can be equipped with to strengthen sealing effectiveness, but when Fluid pressure becomes big, the sealing effectiveness of sealing ring can be deteriorated.
The content of the invention
It is an object of the invention to for drawbacks described above of the prior art, there is provided a kind of anti-leakage valve, it is in valve element
In the case of wearing with the contact surface of valve seat, it can also keep sealing well, and its sealing effectiveness is not because of Fluid pressure
Increase and weaken.
For achieving the above object, present invention employs following technical scheme：A kind of anti-leakage valve, including valve body,
The valve element being installed in the valve body, the valve seat being engaged with the valve element and the valve cage flowed into for fluid, the valve cage
It is connected with the valve seat, annular breach is provided with the valve cage, sealing ring, the sealing ring are provided with the annular breach
It can be bonded with the valve element outer peripheral face, the sealing ring opens up fluted, and fluid can be flowed into the groove and in groove
Wall applies pressure and the outer peripheral face of sealing ring and the valve element is brought into close contact.
In addition, present invention additionally comprises following attached technical scheme：
The valve cage includes the barrier of shaping in conjunction, and the barrier is set close to the valve element and part is supported
By the sealing ring.
The barrier is provided with least one aperture, and the aperture and the groove and fluid are homogeneously intercommunicated.
The sealing ring is provided with contact site, and the contact site protrudes from the barrier, and the contact site can be with the valve
Core outer peripheral face is bonded.
The section of the sealing ring is substantially u-shaped.
The fluid has a fluid high-pressure area, and the opening of the groove is towards fluid high-pressure area.
Annular elastomeric circle is provided with the groove.
The diameter of the annular elastomeric circle is equal to or slightly greater than the groove.
The valve seat offers annular groove, and the annular groove is engaged with the annular breach and accommodates the sealing jointly
Circle.
Compared to prior art, the advantage of the invention is that：Valve has valve element and valve base sealing and sealing ring and valve
The double sealing effect of core sealing；In the case of being revealed even in valve element and valve seat because of abrasion, sealing ring remains unchanged energy
Sealing effectiveness is enough played, moreover, when Fluid pressure is bigger, the sealing effectiveness of sealing ring is better, so as to effectively prevent valve
Leakage, improve sealing.

Embodiment
Technical solution of the present invention is further non-limitingly described in detail below in conjunction with preferred embodiment and its accompanying drawing.
As illustrated, corresponding to a kind of preferred embodiment of anti-leakage valve of the present invention, including valve body 1, valve element 2 and valve
Core 2 is engaged valve seat 3, the valve cage 4 flowed into for fluid, the bonnet 13 of the upper end of sealed valve body 1 and the drive of limitation fluid circulation
The valve rod 14 that movable valve plug 2 moves up and down, is provided with fluid passage 1a in valve body 1, valve element 2 be arranged on fluid passage 1a it is interior and can more than
Lower motion, valve cage 4 offer the duct 4a communicated with fluid passage 1a, and duct 4a is also fluid high-pressure area 4a, valve cage 4 and valve seat
3 is in mating connection.When valve element 2 is in contact with valve seat 3, fluid passage 1a is closed, and prevents the fluid outflow in valve body 1；When
When valve element 2 separates with valve seat 3, fluid can normally circulate, and can be according to duct 4a on the lower surface of valve element 2 and valve cage 4
Position relationship controls the flow of fluid.
The lower surface of valve cage 4 offers annular breach 5, and annular groove 7 is offered on valve seat 3, in annular breach 5 and annular groove 7
It is engaged in the cavity to be formed and is provided with sealing ring 6.Valve cage 4 also includes barrier 8, and barrier 8 is integrally formed with valve cage 4, its
Positioned at annular breach 5 close to the position of the outer peripheral face 16 of valve element 2, for preventing sealing ring 6 from being come off from annular breach 5.Sealing ring 6
Surface offers 18 grooves 9 towards higher-pressure region 4a of opening, and the section of sealing ring 6 is substantially u-shaped.Offered on barrier 8
The aperture 10 communicated with groove 9, aperture 10, groove 9 and fluid passage 1a are interconnected.Annular elastomeric is provided with groove 9
Circle 11, annular elastomeric circle 11 has certain elasticity, metal material or other plastic materials can be used to be made, its diameter is preferably
Width identical with the width of groove 9 or slightly larger than groove 9, so that sealing ring 6 is in the more firm of the interior installation of annular breach 5
Lean on, it is also more close with the outer peripheral face 16 of valve element 2 patch.Sealing ring 6 is additionally provided with the contact site 12 for protruding from barrier 8, contact
The top of portion 12 is provided with arc angling 15, and arc angling 15 can make valve element 2 more smoothly move up and down, and prevent valve element 2 by contact site
12 damage by pressure.When valve element 2 moves to valve seat 3, valve element 2 first contacts with contact site 12, is contacted afterwards with valve seat 3.
When the valve is closed, i.e., when valve element 2 contacts with valve seat 3, fluid flow through orifices road 4a and the outer wall of valve element 2 lead to fluid
The gap that road 1a is formed, is entered in groove 9 by aperture 10 afterwards, can be to groove 9 because fluid has certain pressure
Inwall 17 applies pressure, and the contact site 12 for forcing sealing ring 6 is flared out, so as to tightly touch the outer wall of valve element 2.Now,
Even if the contact surface of valve element 2 and valve seat 3 is revealed because of abrasion, because sealing ring 6 has sealed the fluid above it, also just protect
Having demonstrate,proved the valve will not reveal, moreover, when Fluid pressure is bigger, contact site 12 contacts more with the outer peripheral face 16 of valve element 2
To be close, sealing effectiveness is also better.When the valve is open, fluid normally flows out valve from duct 4a through fluid passage 1a.
The anti-leakage valve of the present invention passes through rational structure design so that valve has valve element and valve base sealing and close
Seal and the double sealing effect of seal spool；In the case that valve element and valve seat are revealed because of abrasion, sealing
Circle still can play sealing effectiveness, moreover, when Fluid pressure is bigger, the sealing effectiveness of sealing ring is better, so as to effectively anti-
Stop the leakage of valve, improve sealing.
It is pointed out that the technical concepts and features of above-mentioned preferred embodiment only to illustrate the invention, its object is to
Allow person skilled in the art to understand present disclosure and implement according to this, the protection of the present invention can not be limited with this
Scope.Any equivalent change or modification in accordance with the spirit of the invention, it should all be included within the scope of the present invention.
