Abstract
The utility model provides a two -way metal -seated ball valve, which comprises the following components: a valve body, be equipped with the valve rod in the valve body, still be equipped with elastic valve seat in the valve body, the valve rod front end is equipped with the spheroid, the valve body is equipped with the disk seat mount pad, fixed mounting has elastic valve seat on the disk seat mount pad, there is first breach groove between elastic valve seat's the bottom and the upper surface of disk seat mount pad, there is second breach groove between the lower surface of disk seat mount pad and the valve body, through setting up first breach groove and second breach groove, the messenger is when high temperature high -pressure medium, valve seal face non -deformable, thereby can not lead to valve leakage, disadvantages such as potential safety hazard have been solved.
Description
Technical field
This utility model is related to valve technology field and in particular to a kind of bidirectional metal sealing ball valve.
Background technology
Bracing type bidirectional metal sealing ball valve combines the advantage of gate valve, stop valve, plug valve and ball valve, its fluid resistance
Little, torsional forces is little, flows to unrestricted, opens and closes quick, structure height is constant, can be used in military project, nuclear power, industrial high temperature, height
In the device of the chemical industry corrosive medium such as pressure, grit, steam, gas, oil product.Solve gate valve, stop valve, plug valve, ball valve
Leakage test of usually dispatching from the factory room temperature No leakage, but when being used in high-temperature high-pressure medium, service life is short, and torsional forces is big, and sealing surface becomes
Shape, so that valve leak, causes the disadvantages such as potential safety hazard.
Content of the invention
In order to solve the deficiencies in the prior art, of the present utility model provide a kind of bidirectional metal sealing ball valve.
The technical solution that this utility model adopts is: a kind of bidirectional metal sealing ball valve, including valve body, described valve
It is provided with valve rod in vivo, in described valve body, is additionally provided with elastic seat, described valve rod front end is provided with spheroid, and described valve body is provided with
Valve seat mounting seat, described valve seat mounting seat is installed with elastic seat, the sealing surface of described elastic seat and spheroid
Lower end and valve seat mounting seat between there is the first gap slot, there is the second breach between described valve seat mounting seat and valve body
Groove.
Between described elastic seat and spheroid, sealing coordinates, and the sealing cone angle between described elastic seat and spheroid is
20°.
Described elastic seat is the font of falling l, the described upper end of the elastic seat of the font of falling l and valve seat mounting seat
There is the first gap slot between upper surface.
Described valve body extends inwardly to form valve seat mounting seat, described extend valve body valve seat mounting seat and valve body
Between there is the second gap slot.
Described elastic seat is made using metal material.
The beneficial effects of the utility model are: this utility model provides a kind of bidirectional metal sealing ball valve, including valve body,
It is provided with valve rod in valve body, in valve body, is additionally provided with elastic seat, valve rod front end is provided with spheroid, and valve body is provided with valve seat mounting seat, valve
It is installed with elastic seat in seat mounting seat, have first between the upper surface of the bottom of elastic seat and valve seat mounting seat and lack
, there is the second gap slot between the lower surface of valve seat mounting seat and valve body, by arranging the first gap slot and the second breach in mouth groove
Groove, makes in high-temperature high-pressure medium, valve sealing face is unlikely to deform, thus not leading to valve leak, solves potential safety hazard
Etc. disadvantage.

Specific embodiment
In conjunction with Fig. 1, Fig. 2, this utility model is further described, a kind of bidirectional metal sealing ball valve, including valve body
1, it is provided with valve rod 2 in described valve body 1, in described valve body 1, is additionally provided with elastic seat 3, described valve rod 2 front end is provided with spheroid
4, described valve body 1 is provided with valve seat mounting seat 11, and described valve seat mounting seat 11 is installed with elastic seat 3, described
There is the first gap slot 5, described valve seat between the lower end of the sealing surface of elastic seat 3 and spheroid 4 and valve seat mounting seat 11
There is the second gap slot 6 between mounting seat 11 and valve body 1.Described elastic seat 3 is the font of falling l, the described font of falling l
There is the first gap slot 5 between the upper surface of the upper end of elastic seat 3 and valve seat mounting seat 11.Described valve body 1 extends internally
Form valve seat mounting seat 11, described extend valve body 1 valve seat mounting seat 11 and valve body 1 between there is the second gap slot 6.
By arranging the first gap slot 5 and the second gap slot 6, make in high-temperature high-pressure medium, valve sealing face is unlikely to deform, thus not
Valve leak can be led to, solve the disadvantages such as potential safety hazard.
Sealing cooperation, the sealed taper between described elastic seat 3 and spheroid 4 between described elastic seat 3 and spheroid 4
Angle is 20 °.
Described elastic seat 3 is made using metal material.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment, all technical schemes belonging under this utility model thinking belong to protection domain of the present utility model.Should refer to
Go out, for those skilled in the art, some improvement under the premise of without departing from this utility model principle and
Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
