摘要： A tubing interface (20) having an elongated tube (21), an elastomeric ferrule (24) and a support ring device (30) disposed around the ferrule (24). The ferrule (24) includes a bore (28) which is sized for receipt of the tube (21). The tubing interface (20) further includes a cap member (31) having an exterior surface (32), an opposed interior surface (33), and a tube receiving passage (35) extending therethrough. The receiving passage (35) is formed and dimensioned for axial sliding receipt of the tube member therethrough. The cap member (31) further includes a cup-shaped receiving recess (36) extending proximally from the interior surface (33), and is formed and dimensioned for axial receipt of the proximal end of the ferrule body member (25) and the support ring (30). When the cap member (31) is mounted to a valve apparatus (29), the support ring (30) and the elastomeric ferrule device (24) compressively cooperate with the cup-shaped recess (36) to form a fluid-tight seal between the tube port (22) and a communication port (45) of the valve apparatus (29).

摘要： A method to test a plug valve seal by embedding a test coupon into the face of the slip. Even the heat energy is averaged by placing the test coupon at the midsection of the slip. During the bond adhesive application all applicable surfaces have the same adhesive applied during the same time frame in the same environment (except under test coupon tab which shall be prevented from adhering mechanically or chemically). The elastomer prepared for the seal groove is identical and is prepared in the same batch as that for the test coupon and all installed with the same tackifying agent by the same individual. The seal cross-section is the same as the test section of the seal test coupon. The post cure is next completed equally on seal and test coupon. After cool down occurs, the test coupon test tab (which was prevented from adhering mechanically or chemically earlier) is released and placed into a pull tab fixture and a varying known load is applied. The elongation is monitored and a stress/strain curve can be generated, verifying material properties. Further pulled to failure, the seal groove adhesion is verified. The removed test tab can then be compression set tested and a variety of other tests can be performed. Material and performance certifications can be generated for each slip seal.

摘要： A valve (12) for controlling the flow of a gas therethrough which requires no machining in order to attain an effective seal between the valve seating surface and a rotatable plug element (26). The valve seat surface (24) remains as-cast while the plug consists of an overmolded plastic. The overmolding defines an array of pliable sealing ridges. The use of overmolding facilitates the use of cost-saving plastic materials and obviates the need for expensive machining of the cooperating surfaces.

摘要： A tapered plug valve having a sealing member (4) on the plug (3) positioned to surround the passageway (7) through the valve casing (1) on the downstream side in the valve closed position. No part of the member (4) is contacted by fluid flowing through the valve while the passageway (7) communicates with the port (6) in the plug (3). As a result the member (4) is less likely to suffer damage from moving liquid, especially if solid particles are present in the fluid.
