But the butterfly valve of this structure is not suitable with dust medium, paste liquid conveying, sealing effect is poor.
Utility model content
In order to overcome the shortcomings of background technology, the utility model provides a kind of high-performance ball face sealing butterfly valve, solves existing
The problem of butterfly valve seal effect is poor.
Technical solution used by the utility model：A kind of high-performance ball face sealing butterfly valve, including valve body, valve rod, dish plate
Component, valve component, bottom cover, driving executive module；The valve rod is set through valve body, and its lower end is equipped with annular spacing groove,
Decile spacing ring in the annular spacing groove is installed, and is coordinated with valve body axial limiting；The valve rod upper end connection driving is held
Row component, the bottom cover is arranged on body base, and coordinates with valve seal；The dish plate component includes dish plate, dish plate seals
Circle, the dish plate are fixedly mounted on valve rod, and the dish plate sealing ring is mounted by means of bolts on dish plate, and the dish plate is close
The spherical seal surface of spherical structure is formed in seal；The valve component includes valve seat, trim ring, and the trim ring passes through bolt
It is fixedly mounted on valve body, the valve seat floating is arranged between valve body and trim ring, is equipped between the valve seat and trim ring, valve body
Flexible graphite sealing ring, cooperation can be sealed with spherical seal surface by being additionally provided on the valve seat seals in the curved surface of a curved-surface structure
Face；The revolution axle center of the dish plate deviates the center of valve seat, the revolution axle center offset spherical seal surface of the dish plate.
At least one layer of sealing ring is equipped between the dish plate sealing ring and dish plate.
The spherical seal surface is formed with curved surface sealing surface using hard alloy overlay welding.
The beneficial effects of the utility model are：Using above scheme, double eccentric settings of dish plate so that it is being opened or is closing
When closing, reduce the contact between spherical seal surface and curved surface sealing surface, reduce friction, open and close it is lighter, spherical seal surface with
Spherical surface between curved surface sealing surface can then be formed with a curved surface cooperation preferably contacts linear sealing firmly, ensures sealing performance,
Valve seat is separately set, and pass through flexible graphite sealing ring existing micro elastic deformation amount in itself with trim ring simultaneously so that valve seat
Micro floating is obtained by medium active force while ensureing initially than on the basis of pressing, it is close to further ensure that it reaches zero leakage
Seal effect.

Specific embodiment
The utility model embodiment is described further below in conjunction with the accompanying drawings：
As shown in the figure, a kind of high-performance ball face sealing butterfly valve, including valve body 1, valve rod 2, dish plate component 3, valve component 4,
Bottom cover 5, driving executive module 6；The valve rod 2 is set through valve body 1, and its lower end is equipped with annular spacing groove 21, the annular
Decile spacing ring 7 in limiting slot 21 is installed, and is coordinated with 1 axial limiting of valve body；2 upper end of the valve rod connection driving execution group
Part 6, the bottom cover 5 is arranged on 1 bottom of valve body, and coordinates with valve seal；
The dish plate component 3 includes dish plate 31, dish plate sealing ring 32, and the dish plate 31 is fixedly mounted on valve rod 2, described
Dish plate sealing ring 32 is mounted by means of bolts on dish plate 31, and the dish plate sealing ring 32 is equipped with by hard alloy overlay welding shape
Into and spherical structure spherical seal surface 321；
The valve component 4 includes valve seat 41, trim ring 42, and the trim ring 42 is mounted by means of bolts on valve body 1, institute
It states the floating of valve seat 41 to be arranged between valve body 1 and trim ring 42, soft graphite is equipped between the valve seat 41 and trim ring 42, valve body 1
Sealing ring 43 is additionally provided on the valve seat 41 and is formed and with being sealed with spherical seal surface 321 in one from hard alloy overlay welding
The curved surface sealing surface 411 of secondary curved-surface structure；
The revolution axle center of the dish plate 31 deviates the center of valve seat, the revolution axle center offset spherical sealed of the dish plate 31
Face.
