Abstract
The utility model discloses a kind of Bidirectional pressure metal sealing latus rectum semisphere valve, including valve body, rotated the hemisphere valve plate being arranged in described valve body by upper and lower valve shaft, and be arranged on the valve seat of valve body import department and described hemisphere valve plate composition sealing pair；Described valve seat is made up of first ring seat and the second ring seat that section configuration is arcuate structure with radially flanging；It is provided with the first annular groove and the second annular groove along fluid flow direction is spaced apart in valve body import department, the flanging of described first ring seat is fixed in described first annular groove, one ring limit of described second ring seat is plugged in described second annular groove, and another ring edge lap of the second ring seat is in the land being opened in the first ring seat.This utility model advantage is effectively to solve two way seal and forward seals and opens the problem that moment of torsion is excessive.
Description
Technical field
This utility model relates to metal sealing semisphere valve, especially relates to Bidirectional pressure metal sealing latus rectum semisphere valve.
Background technology
Metal sealing semisphere valve is widely used in various pipe-line system, and the requirement to it is not only to meet online dimension
The needs repaiied, but also two way seal to be reached, although but current metal sealing semisphere valve meets above-mentioned requirements but existence
Deficiency be forward seal open difficulty, operational torque is excessive.
Summary of the invention
This utility model purpose is to provide a kind of Bidirectional pressure metal sealing latus rectum semisphere valve.
For achieving the above object, this utility model takes following technical proposals:
Bidirectional pressure metal sealing latus rectum semisphere valve described in the utility model, including valve body, is rotated by upper and lower valve shaft and sets
Put the hemisphere valve plate in described valve body, and be arranged on the valve seat of valve body import department and described hemisphere valve plate composition sealing pair；
Described valve seat is made up of first ring seat and the second ring seat that section configuration is arcuate structure with radially flanging；At valve body
Import department is along spaced apart the first annular groove and the second annular groove of being provided with of fluid flow direction, and the flanging of described first ring seat is fixed on institute
Stating in the first annular groove, a ring limit of described second ring seat is plugged in described second annular groove, another ring limit of the second ring seat
It is overlapped in the land being opened in the first ring seat.
The lower end of described upper valve shaft is connected by alignment pin and described hemisphere valve plate are fixing, and T-shaped is passed through in the stage casing of upper valve shaft
Axle sleeve is rotatably assorted with valve body, and described T-shaped axle sleeve is connected with upper valve shaft and valve seal by clamp nut and O-ring seals.
This utility model advantage is the Split type structure that valve seat is arranged to be made up of described first, second ring seat, second
Ring seat uses relatively thin metal ring, has certain metallic elastic, therefore can move to the direction being beneficial to seal when pressurized, from
And reach the performance of two way seal.Described upper valve shaft stage casing is rotatably assorted with valve body by T-shaped axle sleeve, greatly reduces axle pastern
Position moment of friction and sealing surface moment of friction, effectively solve two way seal and forward seals and opens the problem that moment of torsion is excessive.T
Oblique crank Z set is sealedly and fixedly connected with upper valve shaft by clamp nut and O-ring seals, and self-tightening performance is good, life-time service exempt from regulation and
It is easily installed and safeguards.Meanwhile, T-shaped axle sleeve uses model to be the aluminum-bronze material of QAL9-2, has self-lubricating function, extends
Service life.

Detailed description of the invention
As Figure 1-3, Bidirectional pressure metal sealing latus rectum semisphere valve described in the utility model, including valve body 1, passes through
Upper and lower valve shaft 2,3 rotates the hemisphere valve plate 4 that is arranged in valve body 1, and is arranged on valve body 1 import department and constitutes with hemisphere valve plate 4
The valve seat of sealing pair；Valve seat is by having the first ring seat 6 of radially flanging 5 and the second ring seat that section configuration is arcuate structure
7 compositions；It is provided with the first annular groove 8 and the second annular groove 9, outside the first ring seat 6 along fluid flow direction is spaced apart in valve body 1 import department
Flange 5 is fixed in the first annular groove 8 by bolt 10, and a ring limit of the second ring seat 7 is plugged in the second annular groove 9, the second ring
Another ring edge lap of seat 7 is in the land being opened in the first ring seat 6；The lower end of upper valve shaft 2 is by alignment pin 11 and half
Ball valve plate 4 is fixing to be connected, and the stage casing of upper valve shaft 2 is rotatably assorted with valve body 1 by T-shaped axle sleeve 12, and T-shaped axle sleeve 12 is by compressing spiral shell
Mother 13 and O-ring seals 14 are tightly connected with upper valve shaft 2 and valve body 1.
Claims (2)
