Description
Technical field
The utility model relates to valve technology field, is specifically related to a kind of all-welded ball valve two-way double density sealed knot
Structure.
Background technology
Ball valve opening and closing element is driven by valve rod, and the valve rotated around ball valve axis.Also can be used for flowing
The regulation of body and control, seal the metal valve of its V-type core of V-type ball valve and pile-up welding hard alloy the most firmly
There is between Zuo the strongest shearing force, be particularly well-suited to the medium of fibre-bearing, small solid material etc..And
Multi-pass ball valve not only can control the interflow of medium, shunting and the switching flowed on pipeline flexibly, simultaneously
Also can close arbitrary passage and make two other passage be connected.This class valve the most typically should level
Install.Ball valve is divided into according to type of drive: pneumatic ball valve, electrical ball valve, manual ball valve.
Traditional all-welded ball valve, for realizing two way seal, have employed valve seat and adds piston ring 9, adds the 2nd O
The fabricated structure of type circle 10.The second O 10, structure ratio it is respectively arranged with on the inside and outside circle of piston ring 9
More complicated, valve seat volume is relatively big, therefore makes valve volume increase, simultaneously in combined valve seat sealing structure
Heart size compares beats, and under same operating mode, the keying moment of valve increases, and causes consumptive material, power consumption.
Utility model content
The purpose of this utility model is the defect for prior art and deficiency, it is provided that a kind of simple in construction,
The two-way double sealing structure of a kind of all-welded ball valve reasonable in design, easy to use.
For achieving the above object, the technical solution adopted in the utility model is: it comprise spheroid, valve body,
Valve seat, valve seat bracing ring, spring, an O RunddichtringO, valve seat primary seal circle, valve seat secondary seal ring；
Described valve body is connected with spheroid by valve seat；Described valve seat is connected with valve seat bracing ring；Described valve
It is provided with spring between seat supports circle and valve body；An O it is provided with between described valve seat and valve seat bracing ring
RunddichtringO；Valve seat primary seal circle, valve seat and spheroid it is provided with between described valve seat bracing ring and spheroid
Between be provided with valve seat secondary seal ring.
As preferably, a described O RunddichtringO is explosion-proof sealing ring.
As preferably, described valve seat and valve seat bracing ring are integral type structure.
During the utility model operation, under pressure medium effect, an O RunddichtringO is subjected to displacement, and moves
To low-pressure side, its elastic deformation strengthens further simultaneously, fills and closing gap, as long as an O type is close
There is initial pressure in seal, can be achieved with leak free positive confinement.
After using said structure, what the utility model produced has the beneficial effect that described in the utility model one
Kind of the two-way double sealing structure of all-welded ball valve, improves the sealing effectiveness between valve seat and valve body and valve
In service life, the utility model has simple in construction, arranges the advantages such as reasonable, cost of manufacture is low.

It is provided with an O RunddichtringO 6 between described valve seat 3 and valve seat bracing ring 4；Described valve seat props up
It is provided with valve seat primary seal circle 7 between support ring 4 and spheroid 1, between valve seat 3 and spheroid 1, is provided with valve seat
Secondary seal ring 8.
As preferably, a described O RunddichtringO 6 is explosion-proof sealing ring.
As preferably, described valve seat 3 is integral type structure with valve seat bracing ring 4.
During the operation of this detailed description of the invention, under pressure medium effect, there is position in an O RunddichtringO 6
Moving, shift to low-pressure side, its elastic deformation strengthens further simultaneously, fills and closing gap, if an O
There is initial pressure in RunddichtringO 6, can be achieved with leak free positive confinement.
After using said structure, what this detailed description of the invention produced has the beneficial effect that this detailed description of the invention
The described two-way double sealing structure of a kind of all-welded ball valve, improves the sealing effectiveness between valve seat and valve body
With the service life of valve, this detailed description of the invention have simple in construction, arrange rationally, cost of manufacture low
