Description
Technical field
This utility model relates to a kind of ball valve, is specifically related to a kind of high-temperature metal seal ball valve.
Background technology
High-temperature metal seal ball valve is typically made up of valve body, valve seat, spheroid, valve rod, and valve seat is shaped with metallic sealing section and ball
Body metal combination seals, and is axially arranged with spring, makes valve seat can realize valve seat at valve body radial floating between valve seat and valve body
Prevent worst hot case valve seat and spheroid swollen extremely while sealing, between valve seat radially-outer surface and valve body, be provided with carbon seal ring,
Realize the sealing between valve seat and valve body.Its major defect is: the carbon seal ring between valve seat and valve body is by butterfly spring
Granting to load to compress and reach sealing, the face pressure that butterfly spring is granted is that remote deficiency reaches seal request.So valve seat is close
Seal ring can not be fully achieved sealing, needs the grease auxiliary seal when assembling；Reach as increased initial tension of spring further
Better seal, then can increase the friction torque of valve seat and ball.It addition, because sealing ring size and density are variant, after compression
Size also can be variant, the possible overcompression of such spring or insufficient compression, causes valve to seal in use for some time
Ring occurs lax, thus causes seal failure.Such structure needs every deck valve door individually to adjust when valve assembles, and is substantially reduced
The assembling speed of valve, the sealing property simultaneously causing valve is unstable.
Utility model content
This utility model provides a kind of high-temperature metal seal ball valve, which solves existing sealing sealing structure performance
Difference, assembling inconvenience, the problem that sealing property is unstable.
In order to solve the problems referred to above, the high-temperature metal seal ball valve that this utility model provides have employed following technical side
Case:
A kind of high-temperature metal seal ball valve, including valve component, valve seat, spheroid, valve rod, sealing member, valve component includes
Valve body and valve body cap, it is characterised in that: described spheroid is fixed on bearing bracket stand by upper bearing (metal) and lower bearing, described bearing
Frame is installed on valve component, and valve rod is installed on spheroid, between described spheroid and valve component by valve gap and bearing bracket stand
Installing valve seat, seal with sealing member between described valve seat and valve component, described sealing member includes that disk spring, valve seat are close
Seal ring, the first seal joint circle, the second seal joint circle, four cyclizations, holding screw, described valve seat passes through disk spring and valve
Body connects, and valve base sealing ring is installed in the space between upside and the valve body of valve seat, and valve base sealing ring is with the first seal joint circle pressure
Tightly, then with the second seal joint circle clamping, fix with four cyclizations and holding screw, easy for installation, good seal performance, sealing ring
Not thering is provided face to press by spring, thus structure is provided separately face pressure, so enough face pressures can be provided by the demand of sealing
Reach to fully seal.Spring is only used for providing the valve seat primary face pressure to ball, preferably ensure that the sealing property of valve seat.
Preferably, described bearing bracket stand is a frame-type structure with through hole, and valve body clamps bearing bracket stand, and bearing bracket stand is to ball
Body is spacing.
Preferably, described valve base sealing ring is a trapezium structure sealing ring.
Preferably, the first described seal joint circle is a triangular structure pressure ring circle.
The beneficial effects of the utility model are: provide a kind of its simple in construction of high-temperature metal seal ball valve, assembling side
Just, it seals and uses trapezoidal valve base sealing ring, and the first seal joint circle, the second seal joint circle, four cyclizations, holding screw are to ladder
Shape valve base sealing ring carries out spacing, makes sealing property more stable reliably, carries out spheroid spacing more pacifying by bearing bracket stand simultaneously
Complete reliable, improve the service life of high-temperature metal ball valve.
