Abstract
A kind of special material regulating valve sealing pair self-straightening structure, including the valve seat and valve element that coordinate in valve body, fairlead is additionally provided with valve body, valve element top and fairlead mobile guide coordinate, the non-fastening-type of valve seat is seated in valve body, and valve seat lower surface and valve body between be lined with gasket seal, the upper surface of valve seat is pressed with pressing sleeve of valve seat.Of the present utility model rational in infrastructure, the non-fastening-type of valve seat is seated in valve body, though during assembling valve element and valve seat without it is accurate with one heart, valve seat can also fine motion suffer from one's own actions positive adaptation valve element, it is ensured that the performance of sealing pair.Also, valve seat is pressed on the sealing of valve body midplane by pressing sleeve of valve seat, will not deform, valve body and valve base chamber No leakage.The storing of the non-fastening-type of valve seat makes dismounting very convenient, without the need for special tool(s), can be safeguarded with quick-replaceable.
Description
Technical field：This utility model is related to the sealing pair that a kind of regulating valve, particularly valve element and valve seat coordinate.
Background technology：Valve seat in regulating valve is typically all to be fastened in valve body using threaded connection, and needs screw power
Greatly, valve seat may deform, and easily loosen when being threaded in temperature change, root is cut, make between valve seat and valve body produce
Leakage.The mode of screw threads for fastening connection makes valve seat no room to swing a cat, if valve element and valve seat can not accurately with one heart during assembling, meeting
The performance of sealing pair is significantly affected, and the leakage rate for sealing cooperation is bigger than normal, strict special material regulating valve is required especially for being suitable for
Use can be had a strong impact on.In addition, in I＆ M, threaded connection valve seat must use specific purpose tool, not enough facilitate.
The content of the invention：For the deficiencies in the prior art, this utility model provides a kind of rational in infrastructure, valve seat can fine motion spy
Material regulating valve sealing pair self-straightening structure.
This utility model includes the valve seat coordinated in valve body and valve element, is additionally provided with fairlead, on valve element in valve body
Portion and fairlead mobile guide coordinate, and the non-fastening-type of valve seat is seated in valve body, and valve seat lower surface and valve body between be lined with
Gasket seal, the upper surface of valve seat are pressed with pressing sleeve of valve seat.
Of the present utility model rational in infrastructure, the non-fastening-type of valve seat is seated in valve body, even if valve element and valve seat do not have during assembling
Have it is accurate with one heart, valve seat can also fine motion suffer from one's own actions positive adaptation valve element, it is ensured that the performance of sealing pair.Also, valve seat passes through valve seat pressure
Set is pressed on the sealing of valve body midplane, will not deform, valve body and valve base chamber No leakage.The storing of the non-fastening-type of valve seat makes dismounting non-
It is often convenient, without the need for special tool(s), can be safeguarded with quick-replaceable.
This utility model is further illustrated with reference to the accompanying drawings and examples.
Description of the drawings：Fig. 1 is the main structure schematic diagram of embodiment.
Specific embodiment：As illustrated, valve seat 2 and valve element 3 coordinate in being located at valve body 1 constitutes sealing pair, in valve body 1 also
Fairlead 4 is provided with, 3 top of valve element and 4 mobile guide of fairlead coordinate.2 non-fastening-type of valve seat is seated in valve body 1, and valve
Gasket seal 5 is lined between the lower surface of seat 2 and valve body 1, the upper surface of valve seat 2 is pressed with pressing sleeve of valve seat 6.The valve body of the present embodiment
1st, valve seat 2, valve element 3 etc. all adopt titanium, the special material of zirconium class, go for the various operating modes such as high temperature, deep-etching.
2 non-fastening-type of valve seat is seated in valve body 1, in 2 contraposition deviation of valve element 3 and valve seat, valve seat 2 can also fine motion from
Centering adapts to valve element 3, it is ensured that the performance of sealing pair.During valve seat 2 is pressed on valve body 1 by pressing sleeve of valve seat 6 and using gasket seal 5
Flat seal, will not deform, No leakage between valve body 1 and valve seat 2.The upper contact fairlead 4 of the pressing sleeve of valve seat 6 of the present embodiment,
Lower contacts valve seat 2, it is more reasonable so to assemble.The upper and lower end surface construction of valve seat 2 is identical, i.e., valve seat 2 is to spin upside down
Using structure, use so can be easily overturn after 2 one surface wear of valve seat, reduce maintenance cost.
