Specific embodiment
The utility model embodiment is described further with reference to the accompanying drawing:
As shown, a kind of very stiff and demanding room temperature ball face sealing spiral valve, including valve body 1, upper valve rod 2, lower valve rod 3, rotation arc
Face ball 4, valve seat 5, bottom cover 6, driving executive module 7, the rotation cambered surface sphere 4 can be rotatably set in valve by lower valve rod 3
In body 1,2 one end of upper valve rod connection rotation cambered surface sphere 4, the other end stretches out the connection driving executive module 7 of valve body 1, the bottom
Lid 6 is arranged in 1 bottom of valve body, and cooperates with valve seal.
Wherein, driving executive module 7 uses handwheel, is able to drive upper valve rod 2 by rotation hand wheel and rotates, the upper valve rod
2, which are able to drive rotation cambered surface sphere 4, rotates, to realize the movement of valve opening or closing.
The rotation cambered surface sphere 4 is formed with arc sealing surface 41；Valve seat retaining ring 8 is fixedly installed on the valve body 1, it is described
Valve seat 5, which floats, to be arranged between valve body 1 and valve seat retaining ring 8, and at least 2 circle O are equipped between 5 outer ring of valve seat and 1 inner wall of valve body
Type sealing ring 9, inner ring are formed with ring packing boss 51, and the end of the ring packing boss 51 is formed with ball seal face
52, hard sealing cooperation is formed between the arc sealing surface 41 and ball seal face 52.
Realize that hard sealing cooperates by ball seal face 52 and arc sealing surface 41 between valve seat 5 and rotation cambered surface sphere 4, no
The unnecessary abrasion of sealing surface in rotation 4 opening-closing process of cambered surface sphere can be only reduced, and can be realized bigger seal pressure,
Better seal effect is obtained, in addition valve seat 5 floats and is arranged, so that it in reverse pressure-bearing, valve seat 5 can be in the promotion of medium
Under, with rotation 4 synchronization-sliding of cambered surface sphere, so that it is guaranteed that zero leakage.
5 inner ring of valve seat is formed with the ring packing boss 51 for being directed toward rotation 4 center of cambered surface sphere, so that when sealing, ball
The sealing surfaces center of body sealing surface 52 fits with arc sealing surface 41, and stress is more balanced, reduces abrasion, guarantees sealing.
Further, the rotation center of the rotation cambered surface sphere 4 deviates rotation 4 center of cambered surface sphere and 1 center of valve body, is in
Double eccentric structures, double bias be related to so that revolve cambered surface sphere 4 rapidly be detached from valve seat 5, significantly eliminate rotation cambered surface sphere 4 with
It is unnecessary between valve component to squeeze, scrape phenomenon, unlatching resistance is alleviated away from reducing abrasion, improve service life.
Further, the valve seat retaining ring 8 is fixedly mounted on valve body 1 by multiple circumferentially uniformly distributed bolts, structure letter
It is single, it is easy for installation, in order to guarantee to seal, sealing ring 11 is equipped between the valve seat retaining ring 8 and valve body 1, wherein sealing ring can also
Using O-ring seal, structure is simple, easy to assembly.
In addition, the end face inner ring chamfered that the valve seat retaining ring 8 fits with valve seat 5, forms " V " type guide groove 10,
When reverse pressure-bearing, medium can be rapidly introduced into valve seat retaining ring 8 and valve seat 5 by guide groove 9, push valve seat 5, guarantee Bidirectional zero
Leakage.
