Abstract
It the utility model is related to a kind of V-type ball valve, V-type ball valve includes the valve body with valve pocket, valve seat and valve element are provided with valve pocket, the valve seat is fixedly installed in the valve pocket of valve body, one end of the remote valve seat of valve body is media inlet end, one end of the installation valve seat of valve body is medium outflow end, and valve element has the breach towards media inlet end and the sphere towards valve seat when valve element closes valve pocket, sealing ring is provided between valve seat and valve element.When i.e. valve element closes valve pocket, the approach axis of breach on valve element against medium, enter in high-pressure medium it is fashionable can with when valve element deflection it is larger, crush seal circle is preferably coordinated with realizing with valve base sealing, pressure medium is higher, the deflection of valve element is also bigger, and the sealing effectiveness between valve element and valve seat is also better.
Description
Technical field
It the utility model is related to a kind of V-type ball valve.
Background technology
Existing V-type ball valve, as shown in figure 1, including the valve body 1 with valve pocket, valve seat 2, valve element 3, upper valve rod 4 and lower valve
Bar 5, valve element 3 have V-notch 6, and valve seat 2 can be movably set in valve pocket along the axial direction of valve body 1, closed when valve element 3 is gone to
When closing valve pocket, medium can top pressure on the sphere of valve element 3 and on valve seat 2, small deformation can occur for valve element, and the motion of valve seat
Shape journey is larger, valve seat is tightly pressed against on valve element and realizes sealing.But when in the environment used in high-pressure medium, the stroke of valve seat
Necessarily, the deformation of valve element is larger, and it is poor to may result in sealing effectiveness between valve seat and valve element.
The content of the invention
The purpose of this utility model is to provide a kind of suitable high pressure and the preferable V-type ball valve of sealing effectiveness.
To achieve the above object, a kind of V-type ball valve of the present utility model adopts the following technical scheme that：A kind of V-type ball valve, bag
Include the valve body with valve pocket, valve seat and valve element be provided with valve pocket, the valve seat is fixedly installed in the valve pocket of valve body, valve body it is remote
One end from valve seat is media inlet end, and one end of the installation valve seat of valve body is medium outflow end, and valve element has when valve element is closed
The breach towards media inlet end and the sphere towards valve seat, are provided with sealing ring during valve pocket between valve seat and valve element.
Sealing gasket is provided between the valve seat and valve body.
The valve seat is multidiameter structure, and radially-inwardly raised land is provided with the internal face of valve body, and sealing gasket is set
It is placed between the step surface of multidiameter structure and the section of land to realize end face seal.
The sealing ring is arranged on valve seat.
The beneficial effects of the utility model：Valve seat is fixed in valve body, and medium enters from one end of the remote valve seat of valve body,
When i.e. valve element closes valve pocket, breach on valve element against the approach axis of medium, enter in high-pressure medium it is fashionable can with when valve element
Deflection it is larger, crush seal circle with realize preferably with valve base sealing coordinate, pressure medium is higher, the deflection of valve element
Bigger, the sealing effectiveness between valve element and valve seat is also better.
Brief description of the drawings
Fig. 1 is the structural representation of V-type ball valve in background technology；
Fig. 2 is the structural representation of V-type ball valve of the present utility model；
Fig. 3 is partial enlarged drawings of the Fig. 2 at A.
Embodiment
A kind of embodiment one of V-type ball valve of the present utility model：As shown in Fig. 2-Fig. 3, including the valve body 1 with valve pocket,
Valve seat 2 and valve element 3 are installed, the V-type ball valve also includes being connected with valve element 3 so that the upper valve rod 4 that valve element 3 can rotate in valve pocket
With lower valve rod 5, valve seat 2 is fixedly installed in valve pocket by pressing plate, is bolted between pressing plate and valve body 1.
Valve seat 2 is multidiameter structure, and radially-inwardly raised land 9, multidiameter structure are provided with the internal face of valve body 1
Step surface and land section between be provided with sealing gasket 7 to realize end face seal.One end of the remote valve seat 2 of valve body 1 is
Media inlet end, one end of the installation valve seat 2 of valve body 1 is medium outflow end, and valve element 3 has the direction when valve element 3 closes valve pocket
The breach 6 and the sphere towards valve seat 2 of media inlet end, are provided with sealing ring 8 between valve seat 2 and valve element 3, sealing ring 8 is set
In on valve seat 2.Heat preservation carrier gas inlet 10 is additionally provided with valve body 1.
When said structure make it that valve element 3 closes valve pocket, the breach 6 on valve element 3 is situated between against the approach axis of medium in high pressure
Enter in matter it is fashionable can with when valve element 3 deflection it is larger, crush seal circle 8 with realize preferably with valve seat 2 seal coordinate, medium
Pressure is higher, and the deflection of valve element 3 is also bigger, and the sealing effectiveness between valve element 3 and valve seat 2 is also better.
A kind of embodiment two of V-type ball valve of the present utility model, the difference with embodiment one are that sealing ring is arranged at valve
On core.
A kind of embodiment three of V-type ball valve of the present utility model, the difference with embodiment one are that sealing gasket is arranged at valve
In the circumference of seat, without using end face seal.
