Abstract
The utility model provides a ball valve disk seat stable structure, includes valve body, disk seat subassembly, is equipped with sealed the pad between valve body and disk seat subassembly, is equipped with the boss on the disk seat subassembly, be equipped with on the valve body with boss complex recess, the disk seat subassembly compresses tightly on the valve body through the thread bush, is equipped with the round recess of mutually supporting on disk seat subassembly, the valve body, is equipped with the steel ball in the round recess. The beneficial effects of the utility model are that, can prevent that the valve seat subassembly from appearing rotating at valve action in-process and causing the sealed inefficacy between valve seat subassembly and the spheroid, solve the sealed pad seal inefficacy between valve seat subassembly and the valve body when the thread bush is lax under the operating mode such as vibration.
Description
Technical Field
The utility model relates to a ball valve, especially a ball valve disk seat stable structure.
Background
The valve seat structure for the high-temperature ball valve mainly adopts a flexible graphite packing structure at present, and provides sealing specific pressure through combined action of a spring and medium force, so that sealing between the trapezoidal packing and the valve body and the valve seat is realized. The sealing structure of the packing valve seat needs to be filled and simultaneously realizes sealing between the valve body and the valve seat, and in the rotating process of the ball switch, the valve seat can move axially, so that relative friction exists between the valve seat and the valve seat filler and between the valve seat filler and the valve body, and the valve seat filler can generate leakage risk along with the increase of the valve times.
SUMMERY OF THE UTILITY MODEL
In order to solve the prior art not enough, the utility model provides a ball valve disk seat stable structure.
The technical scheme of the utility model a ball valve disk seat stable structure, including valve body, disk seat subassembly, be equipped with sealed the pad between valve body and disk seat subassembly, be equipped with the boss on the disk seat subassembly, be equipped with on the valve body with boss complex recess, disk seat subassembly compress tightly on the valve body through the thread bush, are equipped with the round recess of mutually supporting on disk seat subassembly, the valve body, are equipped with the steel ball in the round recess.
Preferably, the round groove at the upper end of the valve body is a cylindrical through hole, and the steel ball is fixed through a fastener after being loaded.
Preferably, the valve seat assembly and the valve body are provided with mutually matched circular grooves which are semicircular grooves.
The beneficial effects of the utility model are that, the design has the complex recess and the valve seat subassembly cooperation with it on the valve body, can prevent that the valve seat subassembly from appearing rotating at the valve action in-process and causing sealed inefficacy between valve seat subassembly and the spheroid.
The valve seat assembly is provided with a round groove and a steel ball, and sealing failure of a sealing gasket between the valve seat assembly and the valve body can be solved when the threaded sleeve is loosened under working conditions such as vibration of the valve.
Drawings
FIG. 1 is a schematic view of the overall valve structure;
FIG. 2 is an enlarged view of a portion of FIG. 1 at A;
FIG. 3 is a schematic view of a valve seat assembly.
In the figure: 1. a valve body; 2. a valve seat assembly; 3. a threaded sleeve; 4. steel balls; 5. a boss; 6. a gasket; 7. a fastener; 8. a circular groove; 9. a sphere.
Detailed Description
As shown in the figure, a ball valve disk seat stable structure, including valve body 1, disk seat subassembly 2, be equipped with sealed pad 6 between valve body 1 and disk seat subassembly 2, be equipped with boss 6 on the disk seat subassembly 2, be equipped with on the valve body with 6 complex recesses of boss, during the valve assembly, correspond the installation with the recess on the boss 6 on the disk seat subassembly 2 and the valve body 1, then compress tightly disk seat subassembly 2 on valve body 1 with thread bush 3, make sealed pad reach sealed effect. The cooperation between the valve body and the valve seat assembly can prevent the valve seat assembly 2 from rotating in the action process of the valve, so that the sealing between the valve seat assembly 2 and the ball body 9 is invalid. Valve seat subassembly 2 compresses tightly on valve body 1 through thread bush 3, is equipped with the round recess 8 of mutually supporting on valve seat subassembly 2, the valve body 1, is equipped with steel ball 4 in the round recess 8, and steel ball 4 card has realized limit function in the round recess between valve body 1 and valve seat subassembly 2, can prevent that thread bush 3 is not hard up time valve seat subassembly 2 can't compress tightly on valve body 1 and the sealed circumstances of pad inefficacy that appears.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
