Description
Technical field
The utility model relates to ring structure mounting technology fields, and in particular to a kind of assembler of cyclic spring structure
Dress, sealing structure and ball valve.
Background technique
O-ring is widely used in valve industry as sealing element.But the rotproofness and temperature due to rubber material itself make
With limitation, the industry-specific valve in portion is not available O-ring as sealing element.In recent years, one of which of the general stopper ring as O-ring
Alternative solution has been more and more widely used in valve industry.General stopper ring is a kind of height of built-in special spring of U-shaped Teflon
Performance sealing element adds system fluid pressure by spring force appropriate, sealing lip (face) is ejected and gently pushes down and is sealed
Metal covering is to generate very excellent sealing effect.
As shown in Figure 1, the ball valve of O-ring structure, since O-ring is as rubber product, tensile property is superior, can after stretching
To be placed directly in the groove of valve seat, as long as guaranteeing there are enough difference in areas between static pressure face and sealing surface, so that it may obtain foot
Enough big pressure release power realizes the lumen of valve from pressure release to overcome spring force.But general stopper ring collet is generally the modeling of PTFE class
Material products, tensile property want far short of what is expected compared to O-ring, and cannot be restored to original size in short term after stretching.Due to above former
Cause, using general stopper ring in valve at present as sealing element is usually to be attached to general stopper ring open position (as shown in Figure 2), this
Structure may be implemented to seal, but can not achieve lumen from pressure release, therefore limit general stopper ring further using in valve.If
By general stopper ring in the closed groove, can be realized general stopper ring structure valve from pressure release, still, due to being equipped in general stopper ring
Metal spring, during installation, it is easy to destroy the metal spring in general stopper ring, cause to fail, while general stopper ring is after mounting
