Description

Flange connects spiral valve
Technical field
The utility model belongs to valve field, more particularly to a kind of ball valve.The utility model is applied to two-way flow medium Pipeline.
Background technology
In the operating mode of pipeline medium two-way flow, it is desirable to which valve has good two way seal function.At present, can preferably make Valve types for bi-directional medium operating mode mainly have gate valve, butterfly valve, stop valve, ball valve etc., and all kinds valve respectively has excellent lack Point, gate valve, butterfly valve cannot function as regulating valve, and stop valve, ball valve are on large diameter pipeline in use, its bulky, price is held high It is expensive.Therefore, Patent No. CN201420335182.3 " bidirectional flow hard sealing ball valve ", develops a kind of adjustable, volume Small, low-cost two way seal spiral valve.But the reverse sealing property of the spiral valve is poor, or even can not accomplish reversely close Envelope.Because under reverse media effect, spheroid by reverse media thrust, make valve rod left side gap into valve body axis hole compress and Deform to the left, cause ball seal face seal clearance mode occur with sealing surface of seat, leak.
The content of the invention
The purpose of this utility model is the shortcomings that presence for prior art, there is provided a kind of good flange of two way seal performance Connect spiral valve.
The technical solution of the utility model includes valve body, valve seat, valve rod, spheroid, support, transmission mechanism, and valve body uses method Orchid is connected on pipeline, and valve rod is made up of upper valve rod and lower valve rod, upper valve rod upper end and transmission mechanism output axis connection, in valve body Valve seat mounting hole is formed with exit passageway, spheroid is formed with the sphere to be cooperated with valve seat for a side wall of a round panel, The upper and lower part of another side wall of round panel is formed with the upper link being fixedly connected with upper valve rod and is connected down with lower valve rod Link;Mainly valve seat uses self sealss valve seat, and the self sealss valve seat is by seal receptacle, pressure ring, retainer ring, fixed plate group Into seal receptacle is installed on the radial direction step in valve channel, the side plane of seal receptacle one and the radial direction step end in valve channel Gap coordinates between face, the side plane contact of another side plane of seal receptacle and pressure ring, in seal receptacle periphery and valve channel Dynamic sealing coordinates between wall;Retainer ring and fixed plate are arranged on the both sides of valve channel annular convex shoulder by hexagon socket head cap screw, Gu Determine ring and be located at pressure ring side, hexagon socket head cap screw is threadedly coupled through the mounting hole of fixed plate with retainer ring, hexagon socket head cap screw end Through retainer ring screwed hole top pressure on pressure ring end face.
In above technical scheme, terminal pad, upper valve rod periphery and terminal pad endoporus are set between valve body and support It is dynamic to coordinate, the inside step in footpath is formed with the middle part of terminal pad endoporus and is cooperated with the radial direction outer step in the middle part of upper valve rod, is being connected Disk top sets sealed letter.
In above technical scheme, lower stem seal is fixed on valve body lower portion, and its top sets locating shaft and lower link The dynamic radial direction step for coordinating, there is the lower link of support between lower valve rod and its locating shaft of axis hole.
The utility model has the advantages that valve seat uses self sealss valve seat, when forward direction seals, pressure medium promotes round panel, Its sphere is set to press tight sealing engagement with seal receptacle, when reversely sealing, pressure medium promotes pressure ring and seal receptacle to be moved to round panel It is dynamic, fit clearance and deflection when compensation valve rod is pressurized between valve body, seal receptacle is compressed with round panel sphere and seal Coordinate, two way seal performance is good.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
