Filed:

Jun 26, 2000

Appl. No.:

09/603413

Inventors:

Brian Lang - Roanoke VA

Assignee:

Acadia Elastomers Corp. - Roanoke VA

International Classification:

F16K 1504

US Classification:

137 1522, 13753311, 13753319, 137540

Abstract:

A ball valve comprising a seat having a first opening thereon, a housing over the seat having a second opening defined by a flap having an inner and outer diameter, and a ball in the housing, the ball having a diameter great than the inner diameter of the flap. The seat may be formed directly onto a metal insert of a bonded piston seal, or directly onto a wall of any chamber needing a ball valve therein. The housing may be formed as an extension of a piece of rubber used to seal the periphery of the insert or chamber wall. Hence, the housing and insert or chamber wall may be molded together as part of a unitarily formed chamber and ball valve combination.

International Classification:

B23P017/00

US Classification:

029/888000

Abstract:

A method for producing a gasket insert comprising: providing a strip of insert material having a predetermined thickness; providing a pair of rigid parallel surfaces spaced apart by a distance approximately equal to, but greater than, the thickness of the insert material; placing the insert material between the surfaces; and bending the insert material to a desired shape. Also disclosed is a method for producing a gasket comprising: providing a strip of insert material having a predetermined thickness; providing a pair of rigid parallel surfaces spaced apart by a distance approximately equal to, but greater than, thickness of the insert material; placing the insert material between the surfaces; bending the insert material to a desired shape; and molding an elastomeric material to the insert.
