Abstract
The invention belongs to sealing structures, and in particular to a kind of hard seal butterfly valve all-metal elastic seal ring.Valve rod is arranged at the internal cavities of valve body for a kind of hard seal butterfly valve all-metal elastic seal ring, including valve body, and valve rod is fixed on valve inner by butterfly plate, and elastic circular arc sealing ring is contacted with the sealing surface of seat inner wall of valve body.The remarkable result of the application is: using whole all-metal sealing circle, cancelling soft graphite interlayer, washes away loss to soft graphite so as to avoid pipeline medium；Sealing ring stretch out an arc-shaped elastic lip, elastic lip with a thickness of 3mm-5mm so that sealing ring has preferable elasticity, good sealing performance easy to form；Elastic lip circular arc is stretched to the major part direction of the valve base sealing conical surface, and pressure medium is acted on the inside of elastic lip circular arc, increases sealing force using pressure medium, can enhance sealing effect.
Description
Technical field
The invention belongs to sealing structures, and in particular to a kind of hard seal butterfly valve all-metal elastic seal ring.
Background technique
Three eccentricity hard seal butterfly valve is on the basis of double eccentric (see the A and B in Fig. 1) by valve seat center line and valve body center
Line is tilting, forms an eccentric angle (see the C in Fig. 1), and designs on valve clack sealing surface with the corresponding geometry of unification,
Make flap in 90 ° of switch rotational travels, is turned round after valve is closed by valve rod between sealing ring and valve seat entirely without any friction
Square forms seal pressure between sealing ring and valve seat, to guarantee valve tight closing.Three-eccentric-butterfly-valve is in 0 ° of -90 ° of unlatching
In the process, sealing ring can be detached from sealing surface of seat in the moment of unlatching, and it is in 90 ° of -0 ° of closing process, only in closing
Moment, sealing ring can just contact and compress sealing surface of seat.Butterfly plate sealing surface is relative to valve base sealing when three-eccentric-butterfly-valve opens and closes
Face is gradually to go out to be detached from and be fade-in compression, eliminates mechanical wear and scratch between two sealing surfaces.
Valve clack sealing ring generally uses the organization plan of multiple layer metal folder soft graphite, to combine hard sealing (metal)
The advantages of with soft seal (soft graphite), three eccentricity hard seal butterfly valve had both been set to have high temperature application conditions, but also with good close
Sealing property.But its disadvantage is also obvious, and soft graphite therein is easy to be washed away loss by medium in the process of running, so that close
Sealing property is difficult to ensure.
Summary of the invention
The purpose of the application is in view of the drawbacks of the prior art, to provide a kind of hard seal butterfly valve all-metal elastic packing
Circle.
The technical solution of the application is: a kind of hard seal butterfly valve all-metal elastic seal ring, including valve body, valve body it is interior
Valve rod is set at portion's cavity, and valve rod is fixed on valve inner, the sealing surface of seat of elastic circular arc sealing ring and valve body by butterfly plate
Inner wall contact.
A kind of hard seal butterfly valve all-metal elastic seal ring as described above, wherein the circular arc of elastic circular arc sealing ring
It is stretched to the major part direction of the valve base sealing conical surface.
A kind of hard seal butterfly valve all-metal elastic seal ring as described above, wherein the elastic circular arc sealing ring
With a thickness of 3mm-5mm.
A kind of hard seal butterfly valve all-metal elastic seal ring as described above, wherein the two of elastic circular arc sealing ring
A gasket is respectively arranged in side, and gasket is fixed on above butterfly plate by pressing plate and screw.
The remarkable result of the application is: using whole all-metal sealing circle, cancelling soft graphite interlayer, so as to avoid pipe
Track media washes away loss to soft graphite；Sealing ring stretch out an arc-shaped elastic lip, elastic lip with a thickness of 3mm-
5mm, so that sealing ring has preferable elasticity, good sealing performance easy to form；Elastic lip circular arc is to the valve base sealing conical surface
The stretching, extension of major part direction, pressure medium is acted on the inside of elastic lip circular arc, increases sealing force using pressure medium,
Sealing effect can be enhanced.

Label shown in attached drawing: 1. valve bodies, 2. valve clack sealing rings, 3. valve rods, 4. sealing surface of seats, 5. elastic circular arc sealings
Circle, 6. gaskets, 7. butterfly plates, 8. pressing plates, 9. screws.
Specific embodiment
The application is described further with reference to the accompanying drawing:
As shown in the picture, a kind of hard seal butterfly valve all-metal elastic seal ring, it is each on elastic circular arc lip sealing ring both sides
One gasket is set, is fixed on above butterfly plate by pressing plate and screw, sealing ring stretches out an arc-shaped elastic lip, elastic lip
With a thickness of 3mm-5mm, the circular arc of elastic lip is stretched to the major part direction of the valve base sealing conical surface.
Realize that technical characterstic of the invention has:
1. whole all-metal structure
Using whole all-metal material, cancels soft graphite interlayer, avoid pipeline medium and soft graphite is washed away
It is lost.
2. elastic circular arc lip sealing ring
Sealing ring stretches out an arc-shaped elastic lip, elastic lip with a thickness of 3mm-5mm, the circular arc of elastic lip is to valve seat
It stretches in the major part direction of sealing cone.
