Abstract
A kind of diaphragm valve holder structure of ball valve, including valve seat, valve seat is equipped with the sealing surface with ball seal, spring assembly is axially set between valve seat and valve body, spring assembly includes spring support seat and spring, valve seat is polymorphic structure, including valve seat body, slim transition plate and extend sealing, slim transition plate is arranged in valve seat body upper surface, extend sealing to connect with slim transition plate, the sealed end for extending sealing protrudes into the seal chamber between valve body and valve deck, extends flange gasket in being arranged between sealing side wall and valve body and valve deck.The utility model has the beneficial effects that, eliminate the sealing ring sealing between valve seat and valve body, using special-shaped valve seat, it is an integral structure, it is directly protruding between valve body and valve deck, the leakage point between valve seat and valve body is eliminated, the leakage between valve seat and valve body due to caused by ring wear is avoided.
Description
Technical field
The utility model relates to a kind of ball valve, in particular to a kind of diaphragm type valve seat.
Background technique
In the prior art, there are leakage points between the valve seat and valve body of ball valve, are sealed by sealing ring, valve body and valve deck it
Between there are leakage points, sealed by middle flange gasket, this structure, valve entirety leakage point is more, and due in valve opening and closing
In the process, valve seat has microdisplacement presence under the action of the spring, leads to the ring wear between valve seat and valve body, it is necessary to fixed
Phase replacement, otherwise will lead to leakage accident, reduces the service life of valve.
Summary of the invention
To overcome existing ball valve drawbacks described above, the utility model provides a kind of reduction valve leak point, extends valve and uses
The diaphragm valve holder structure in service life.
The utility model solve its technical problem the technical solution adopted is that a kind of ball valve diaphragm valve holder structure, including
Valve seat, valve seat are equipped with the sealing surface with ball seal, spring assembly are axially arranged between valve seat and valve body, spring assembly includes
Spring support seat and spring, valve seat are polymorphic structure, including valve seat body, slim transition plate and extend sealing, slim
Transition plate setting extends sealing and connect with slim transition plate, the sealed end for extending sealing protrudes into valve seat body upper surface
Seal chamber between valve body and valve deck extends flange gasket in being arranged between sealing side wall and valve body and valve deck.
Extend sealing and be equipped with fixed part, fixed part is a boss, and boss is mounted in the mounting groove of valve body.
The utility model has the beneficial effects that the sealing ring sealing between valve seat and valve body is eliminated, using special-shaped valve seat,
It is an integral structure, is directly protruding between valve body and valve deck, eliminate the leakage point between valve seat and valve body, avoid due to close
Valve seat caused by seal is worn and the leakage between valve body.Slim transition plate is provided on valve seat, elastic construction can guarantee
The axial movement of valve seat is not influenced during valve opening and closing.The setting of boss, is embedded into valve body, increases the steady of valve seat
It is qualitative.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.

Specific embodiment
As shown in Figure 1, a kind of diaphragm valve holder structure of ball valve, including valve seat 14, valve seat 14 are equipped with close with sphere 11
The sealing surface 10 of envelope, is axially arranged spring assembly between valve seat 14 and valve body 12, spring assembly includes spring support seat 8 and bullet
Spring 9, spring assembly provide the pretightning force that valve seat 14 and sphere 11 seal, and valve seat 14 is polymorphic structure, including valve seat body 7, thin
Type transition plate 4 and extension sealing 3, in 7 upper surface of valve seat body, slim transition plate 4 is elasticity knot for the slim setting of transition plate 4
Structure does not influence the left and right displacement of valve seat 14 during valve opening and closing, extends sealing 3 and connect with slim transition plate 4, extends close
The sealed end in envelope portion 3 protrudes into the seal chamber 1 between valve body 12 and valve deck 13, extends 3 side wall of sealing and valve body 12 and valve deck
Flange gasket 2 in setting between 13.
Further, extend on sealing 3 and set a boss 5, boss 5 is mounted in the mounting groove 6 of valve body 12.
