Abstract
The utility model is related to a kind of valve seat constructions of high-temperature metal seal floating ball valve, including valve body, spring, valve seat, sphere and spring base, the valve seat is step structure, there is spring base between the step surface and valve body of valve seat, spring socket sleeve has valve seat filler on valve seat between the outer circumference surface and valve body of valve seat, valve seat filler is located between the axial end face and valve body of spring base, there is spring eye at the step surface of valve seat, spring is mounted in spring eye, and spring base compresses valve seat filler under the action of the spring.The utility model spring base built in spring, will avoid helical spring exposed in the medium, and the utility model assembling is simple, it is easy to operate, the dust seal at valve seat can be achieved, avoid spring hole plug being caused to reduce valve base seal property because of dust, improve the sealing performance of valve.
Description
Technical field
The utility model is related to valve technology field more particularly to a kind of valve seat knots of high-temperature metal seal floating ball valve
Structure.
Background technology
Existing valve seat construction as shown in Figure 1, mainly include valve body (serial number 1), valve seat (serial number 3), sphere (serial number 4),
Spring (serial number 2), spring is mounted in the spring eye of valve body, and during valve working, spring is exposed in the medium, and existing structure is prevented
Dirt effect is poor, particularly when medium enters spring hole site, spring hole plug so that spring can not be desirable to provide preload
Power, so as to influence the sealing performance of valve.
Utility model content
The utility model is intended to provide the valve seat construction of high-temperature metal seal floating ball valve, can sense, shows and record
The weight of patient.
In order to achieve the above objectives, the technical solution adopted in the utility model is as follows：
A kind of valve seat construction of high-temperature metal seal floating ball valve, including valve body, spring, valve seat, sphere and spring base, institute
Valve seat is stated as step structure, has spring base between the step surface and valve body of valve seat, spring socket sleeve is on valve seat, the excircle of valve seat
There is valve seat filler between face and valve body, valve seat filler is located between the axial end face and valve body of spring base, at the step surface of valve seat
There is spring eye, spring is mounted in spring eye, and spring base compresses valve seat filler under the action of the spring.
Wherein, the spring is helical spring.
Further, the valve seat filler is right-angled trapezium filler or right angled triangle filler.
Wherein, the spring base is step structure, has the hierarchic structure being adapted to spring base on valve body.
Compared with prior art, the utility model has the advantages that：
The utility model spring base built in spring, will avoid helical spring exposed in the medium, the utility model assembling
Simply, it is easy to operate, it can be achieved that dust seal at valve seat, avoids spring hole plug being caused to drop valve base seal property because of dust
It is low, improve the sealing performance of valve.
Description of the drawings
Fig. 1 is the structure diagram of the prior art；
Fig. 2 is the structure diagram of the utility model；
In figure：1- valve bodies, 2- springs, 3- valve seats, 4- spheres, 5- valve seats filler, 6- spring bases.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing, to this reality
It is further elaborated with novel.
As shown in Fig. 2, the valve seat construction of high-temperature metal seal floating ball valve disclosed in the utility model, including valve body 1, bullet
Spring 2, valve seat 3, sphere 4 and spring base 6, valve seat 3 are step structure, have spring base 6, bullet between the step surface of valve seat 3 and valve body 1
Spring abutment 6 is sleeved on valve seat 3, there is valve seat filler 5 between the outer circumference surface of valve seat 3 and valve body 1, and valve seat filler 5 is located at spring base 6
Between axial end face and valve body 1, there is spring eye at the step surface of valve seat 3, spring 2 is mounted in spring eye, and spring base 6 is in spring 2
Under the action of compress valve seat filler 5.
Wherein, spring 2 is helical spring.Valve seat filler 5 is right-angled trapezium filler or right angled triangle filler.Spring base 6
It is pressed on the right-angle side of valve seat filler 5.Spring base 6 is step structure, has the hierarchic structure being adapted to spring base 6 on valve body 1.
The utility model designs spring eye on valve seat, with spring seat structure by helical spring " built-in ".Valve body and valve
Have the filling of valve seat filler between seat, blocking dust during valve working, particle medium enter spring eye；And spring base is in spiral
Under the thrust of spring, valve seat filler is compressed, ensure that pretightning force required during the work of valve seat filler.When dust passes through valve seat
When, spring eye will not be entered, preventing, which influences helical spring, provides pretightning force, reduces the risk of valve base sealing failure, improves
The service life of valve.
Certainly, the utility model can also have other numerous embodiments, without departing substantially from the spirit of the present invention and its essence
In the case of, those skilled in the art can make various corresponding changes and deformation, but these according to the utility model
It is corresponding to change and deform the scope of the claims that all belong to appended by the utility model.
