Description

With the combined type ball valve of bellows
Technical field
The present invention relates to valve field, relate to a kind of combined type ball valve with bellows or rather.
Background technique
Ball valve is mainly used to make the flow direction cutting off, distribute and change medium in pipeline.Bellows is applied comparatively extensive in pipeline, instrument and apparatus, also often coordinates ball valve to use.But current ball valve and bellows are what to separate, both are separate parts.During use, corrugated tube end is connected on the joint of ball valve, is connected between the two by modes such as screw threads.There is following defect in the structure of this kind of prior art: is connected by modes such as screw threads between bellows with ball valve joint, and increase the leak source that leaks, it is unreliable namely to connect between the two, the risk that may there is gas leakage or leak.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of combined type ball valve eliminating the band bellows of the leak source that leaks between bellows and ball valve.
Technical solution of the present invention is, provides a kind of combined type ball valve with the band bellows of following structure, comprises valve body and the spool of band entrance point and outlet end; Described spool is arranged in described valve body; The both sides of described spool are equipped with Sealing; One end of described bellows is fixedly connected with the outlet end of described valve body; The end face of one end of this bellows is against on the Sealing of valve outlet end.
After adopting above structure, the combined type ball valve of band bellows of the present invention, compared with prior art, has the following advantages:
Because one end of bellows of the combined type ball valve of band bellows of the present invention is fixedly connected with the outlet end of valve body, reduce the connection mouth between bellows and valve body, namely the leak source that leaks between bellows and valve body is reduced, connect comparatively reliable between the two, eliminate between bellows and valve body and there is the risk of leaking gas or leaking.In addition, joint is provided with between bellows and valve body in prior art, joint plays the effect of connection, joint is also for being against on the Sealing of valve outlet end for being arranged in valve body by spool simultaneously, combined type ball valve of the present invention eliminates joint, the end face of one end of bellows to be against on the Sealing of valve outlet end for being arranged in valve body by spool, makes structure compacter, also can reduce cost of production simultaneously.
As a modification of the present invention, one end of described bellows and the outlet end of described valve body are welded and fixed.After adopting this kind of structure, connect more reliable between the two.
Improve as another kind of the present invention, the outer side wall of one end of described bellows is provided with position limiting convex ring; Described position limiting convex ring is spacing outside the outlet end of described valve body.After adopting this kind of structure, after described bellows is in place, position limiting convex ring is just spacing on the outlet end of valve body, conveniently installs bellows.
Also have a kind of improvement as of the present invention, the madial wall that the Sealing of described spool both sides contacts with spool is equipped with scrobicular ring; The outer side wall of described Sealing is equipped with stress reduction face.After adopting this kind of structure, described scrobicular ring both sides contact with spool face, form two seals circle, also reduce the area of contact between Sealing and spool simultaneously, namely meet the seal action between spool and Sealing, also reduce open and close torque simultaneously, make Spool rotating more flexible, when user is used, energy easily rotatable handle, more convenient to use.The pressure suffered by Sealing can be alleviated in described stress reduction face, makes structure more reliable.
Also have a kind of improvement as of the present invention, the scrobicular ring on described Sealing is arc scrobicular ring, and the dual-side of described arc scrobicular ring contacts with described spool face; The middle part in the stress reduction face on described Sealing is provided with right angle groove.After adopting this kind of structure, the dual-side of arc scrobicular ring contacts with spool face, and the moment of torsion between Sealing and spool is less.Described right angle groove can be released the pressure, and can reduce Sealing compressive deformation.
Also have a kind of improvement as of the present invention, the middle part of the madial wall that described Sealing contacts with spool is provided with semicircle scrobicular ring; Stress reduction face on described Sealing is R edged surface.After adopting this kind of structure, the both sides of first circular scrobicular ring of Sealing contact with spool face, and the moment of torsion between Sealing and spool is less.Stress reduction face on described Sealing is R edged surface, can reduce Sealing compressive deformation.
Also have a kind of improvement as of the present invention, the madial wall that the Sealing of described spool both sides contacts with spool is equipped with the arc shaped surface tangent with described valve core outer surface; Stress reduction face on described Sealing is inclined-plane.After adopting this kind of structure, place tangent between described Sealing and spool is linear contact lay, and the moment of torsion between Sealing and spool is less.Stress reduction face on described Sealing is inclined-plane, can reduce Sealing compressive deformation.
Also have a kind of improvement as of the present invention, the madial wall that the Sealing of described spool both sides contacts with spool is equipped with conical surface; Stress reduction face on described Sealing is inclined-plane.After adopting this kind of structure, be linear contact lay between described Sealing and spool, the moment of torsion between Sealing and spool is less.Stress reduction face on described Sealing is inclined-plane, can reduce Sealing compressive deformation.
Also have a kind of improvement as of the present invention, the madial wall that the Sealing of described spool both sides contacts with spool is equipped with the R edged surface tangent with described valve core outer surface; Stress reduction face on described Sealing is inclined-plane.After adopting this kind of structure, be linear contact lay between described Sealing and spool, the moment of torsion between Sealing and spool is less.Stress reduction face on described Sealing is inclined-plane, can reduce Sealing compressive deformation.
