Description
Technical field
This utility model relates to field of fluid control, is specifically related to a kind of high-temperature metal sealed elastic ball valve.
Background technology
Because ball valve has, fluid resistance is little, easy to operate, open and close the advantages such as rapid, therefore at petrochemical industry, long-distance transport pipes
And the industry such as urban heat supplying is widely used.Ball valve can be divided into soft sealing ball valve with hard according to the difference of its seat material
Seal ball-valve, wherein, the valve seat of soft sealing ball valve uses politef or filled polytetrafluoroethylene, and it applies in general to temperature
Fluid less than 200 DEG C；The valve seat of hard seal ball valve uses metal to make, and it applies in general to the temperature stream higher than 250 DEG C
Body.When in existing hard seal ball valve work process, its valve seat is shifted under the touching repeatedly of spheroid, between valve seat and valve body
Sealing property be deteriorated, fluid is easily from the clearance leakage between valve seat and valve body, thus has influence on the normal use of ball valve.
Utility model content
The purpose of this utility model is to provide one and is avoided that fluid leaks, thus the high-temperature metal strengthening sealing property is close
Envelope elastic ball valve.
To achieve these goals, the technical solution adopted in the utility model is: a kind of high-temperature metal sealed elastic ball valve,
Including valve body, being provided with spheroid and valve seat in described valve body, described valve seat coordinates with ball seal, it is characterised in that: described valve seat
For endless metal valve seat, valve seat one end is the sealing surface coordinated with ball seal, and the other end offsets with valve body, on valve seat medial surface
And the cyclic spring groove of indent is set at sealing surface.
This utility model is further arranged to, and the other end of described valve seat is offseted with valve body by spring, and valve body sets
There is the groove of putting spring.
This utility model is further arranged to, and the lateral surface of described valve seat is provided with cannelure groove, and this annular groove
The other end running through valve seat is arranged, and is provided with filler in described annular groove, and filler is for the sealing between valve seat and valve body, valve seat
And arranging the connector that a cross section is L-shaped between spring, this connector one end offsets with spring, and it is recessed that the other end stretches into described annular
Groove offsets with filler, at the other end of described valve seat and its medial surface close, extends an annular boss being coaxial therewith, institute
State connector to become to be socketed on described annular boss setting.
This utility model is further arranged to, and described connector is provided with the projection stretching in spring, is used for the company of restriction
Circumferentially rotating of fitting.
This utility model is further arranged to, and the face that described connector and filler offset is towards the inclination outside it
Face.
The beneficial effects of the utility model: high-temperature metal sealed elastic ball valve provided by the utility model, it has double
Weight elastic packing effect, wherein valve seat itself is provided with the cyclic spring groove of indent, makes the contact jaw at valve base sealing to concave
Cyclic spring groove generation elastic deformation, additionally the spring between valve seat and valve body also can make between valve seat and spheroid formed elasticity
Sealing, this double elastic seals and arranges the sealing property that can effectively guarantee ball valve.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Below
Embodiment is used for illustrating this utility model, but is not limited to scope of the present utility model.
Below with reference to Fig. 1 to Fig. 3, this utility model is illustrated.
A kind of high-temperature metal sealed elastic ball valve, including valve body 1, is provided with spheroid 2 and valve seat 3, described valve in described valve body 1
Seat 3 seals with spheroid 2 and coordinates, and described valve seat 3 is endless metal valve seat, and valve seat 3 one end is the sealing surface coordinated with ball seal
4, the other end offsets with valve body 1, on valve seat 3 medial surface and arranges the cyclic spring groove 5 of indent at sealing surface 4.Elastic groove 5
The setting sealed end that makes valve seat 3 contact with spheroid 2 to elastic groove 5, trickle elastic deformation can occur when being squeezed, make
Valve seat 3 and spheroid 2 form elastic packing.
The other end of described valve seat 3 is offseted with valve body 1 by spring 6, and valve body 1 is provided with the groove 7 of putting spring 6.Bullet
Can be moved to side, spring 6 place when the setting of spring 6 makes valve seat 3 be squeezed, make valve seat 3 and spheroid 2 form elastic packing.
Above-mentioned double elastic seals and arranges so that the sealing property between valve seat 3 and spheroid 2 obtains good guarantee, from
And avoid the leakage of fluid.
The lateral surface of valve seat 3 is provided with cannelure groove 8, and this annular groove 8 runs through the other end setting of valve seat 3, described
Being provided with filler 9 in annular groove 8, filler 9, for the sealing between valve seat 3 and valve body 1, arranges one section between valve seat 3 and spring 6
Face is the connector 10 of L-shaped, and this connector 10 one end offsets with spring 6, the other end stretch in described annular groove 8 with filler 9
Offset, at the other end of described valve seat 3 and its medial surface close, extend an annular boss 11 being coaxial therewith, described connector
