The industries such as medicine, water conservancy, electric power, municipal administration, iron and steel, for blocking or connect the medium in pipeline.
The sealing principle of ball valve mainly installs a spool by valve inner, when valve is in opening,
Through hole in the middle of spool and the import and export conducting at valve body two ends, form pipeline.During closedown, only need to pass through valve rod
Drive Spool rotating 90 °, utilize the sphere of spool to be closed by pipeline.For preventing valve internal from revealing, valve seat
Sealing surface is constituted with spool sphere.Sealing between valve seat and spool is most important thus, but at valve seat
With spool with the use of in, spring is set behind at valve seat, be ensure that by the compression pretightning force of spring
The valve seat of ball valve and spool can gluing, sealing closely, but sometimes act on the pressure on valve seat due to medium
Power increases, and makes valve seat increase with the friction of valve core chamber, and moment when causing being turned on and off valve increases, right
The performance requirement of actuating device improves, and increases use cost.
Utility model content
The technical problems to be solved in the utility model is: relatively big by pressure medium area in order to solve existing valve seat,
Cause valve seat to strengthen with spool frictional force, use the technical problems such as actuating device cost increase, this utility model
A kind of ball valve sealing valve seat is provided, to reach to reduce seal pressure, reduces the purpose of use cost.
This utility model solves its technical problem and be the technical scheme is that a kind of ball valve sealing valve seat, bag
Include spool, valve seat, valve body, valve seat support, spring and guard ring, valve seat is installed, in valve seat in described valve body
Rotating coaxially and be provided with spool, described valve seat support is arranged between valve body and valve seat, and described guard ring is arranged on
In valve body, guard ring fits with the outer face of valve seat support, and spring top is contained between valve seat and guard ring, valve seat
Being fitted tightly with spool by the elastic force of spring, the inwall of valve seat support is tightly connected with the outer wall of valve seat, valve
The outer wall of seat support is connected with the inner wall sealing of valve body.This utility model is by increasing between valve seat and valve body
Add valve seat support, reduce the seal pressure of valve seat and valve core chamber.
Further, concrete Hermetical connecting structure is: the outer wall of described valve seat fits with valve seat support, institute
The inwall place of fitting stating valve seat outer wall and valve seat support offers the valve seat groove of circumference, outside valve seat support
Wall and the valve interior wall place of fitting offer the valve seat support groove of circumference, described valve seat support groove and valve seat
Sealing ring it is mounted in groove.Valve seat support groove and valve seat groove can set quantity as required.
In order to the medium power on valve seat support is transferred on valve body, as preferably, outside described valve seat support
Being provided with the boss of integrative-structure on wall at the outer face of valve seat support, the inwall of valve body is provided with step surface,
The outer face of the outer face of boss and valve seat support is on the same face, and the inner face of boss fits with step surface.
The setting of boss can be transferred on valve body the medium power acted on valve seat support, makes to act on valve seat
Medium power reduce, reduce the frictional force of valve seat and valve core chamber, it is achieved more effectively sealing effectiveness simultaneously,
The moment making valve opening and closing reduces, and reduces the use cost of actuating device.
The beneficial effects of the utility model are, a kind of ball valve sealing valve seat of the present utility model, by valve seat
And increase valve seat support between valve body, reduce the seal pressure of valve seat and valve core chamber；Meanwhile, at valve seat support
Boss is set with valve body connection, the medium power acted on valve seat support is transferred to, on valve body, make work
The medium power being used on valve seat reduces, and reduces the frictional force of valve seat and valve core chamber simultaneously, it is achieved more effectively
Sealing effectiveness so that the moment of valve opening and closing reduces, and reduces the use cost of actuating device.
Accompanying drawing explanation
