Abstract
A sealing liner is provided with incorporated reaction ring, including two circular substantially concentric sealing elements, namely: a static sealing element and a dynamic sealing element these two elements being connected together by a sealed membrane. The dynamic sealing element has an annular housing containing a resilient deformable bed against which a reaction ring is held applied.
Claims18
A valve comprising:
- body means having inner chamber means providing for flow through the body;
- closure means supported in said body means and controlling flow in said chamber means;
- flange means secured to said body means;
- radial annular cavity means formed in said body means and flange means and opening into said chamber means;
- and
- sealing liner means in said cavity having first and second circular and substantially concentric sealing means connected together by resiliently deformable means, with said first sealing means providing a static seal in said cavity and said second sealing means providing a dynamic seal with said closure means;
- said second sealing means comprising:
- annular resiliently deformable spring means,
- floating reaction ring means spaced from said first sealing means, and
- sealing housing means having two opposite radial walls confining said spring means and said ring means and preventing movement therebetween along their axes,
- said housing means having a portion interconnecting said radial walls and providing a circular sealing surface for engaging a sealing surface on said closure means,
- said housing portion and said spring means compressed between said closure means and said ring means when said closure means is in the closed position.
