Description
Technical field
This utility model relates to ball valve technical field, especially relates to a kind of valve seat internal high-voltage type inflatable flexible sealing
Circle seal ball-valve.
Background technology
It is known that domestic and international at present, fixing spherical ball valve typically uses the sealing structure of floating valve seat form, i.e. ball (valve
Core) fixing, valve seat floats, valve seat rely on be positioned over end face the elastic force that produces of spring and the pressure of medium jointly that valve seat is tight
Tight pushes spheroid to and sets up seal pressure.
In general, valve designer and manufacturer wishes to reduce as far as possible or be completely eliminated outside sealing surface of seat and spheroid
The gap on surface, thus reach to reduce the purpose of the risk of leakage of valve.
From the point of view of at present, valve seat mainly has 3 kinds of structure types with the sealing structure of spheroid, it may be assumed that
1, very stiff and demanding sealing structure type: (i.e. valve seat and ball seal face is hard metal structure, realizes between the two
Sealing between hard structure and hard structure).
2, the soft sealing structure type boldly confronted a powerful opponent: (i.e. valve seat is soft structures (i.e. flexible material), but spheroid is hard metal
Structure, realizes the sealing between soft structures and hard structure between the two).
3, soft very stiff and demanding sealing structure type is added: (i.e. valve seat is that hard metal adds soft material composition, but spheroid be hard golden
Belong to, realize the sealing between soft hard structure and hard structure between the two).
Under normal circumstances, valve is during opening and closing, and spheroid rotates, and is adjacent to sealing surface of seat together all the time
Under spring force and pressure medium effect, abrasion is produced with sphere；After the long or short time, when abrasion reaches certain
After degree, valve will leak, and finally causes valve invalidation because leakage exceeds standard.
But it is clear that the sealing surface of above-mentioned 3 kinds of main sealing structure types, valve seat and spheroid all can be because of ball body of valve
Rotate and wear and tear, therefore traditional above-mentioned 3 kinds of ball valves sealing structure type are installed and all exist easy to wear, the easily technology of leakage
Defect.
Therefore, how to reduce spheroid to rotate the sealing surface wear of valve seat and the spheroid caused, how to compensate sealing surface of seat
Abrasion, how to make sealing surface of seat can fit completely with sphere all the time, this be ball valve design manufacture have been working hard solve
Problem.
