Sistema de ensamblaje sin soldaduras que comprende un tramo de tubería de acoplamiento (7) uno de cuyos extremos se fija a una válvula de fondo (1), y el otro a un acoplador (2) donde en cada uno de los extremos de la tubería de conexión (7) se dispone una brida central (3), junto con una contra brida (4), y en la unión entre la contra brida (4) y la brida central (3) se dispone un anillo de retención en acero galvanizado (6), mientras que entre la brida central (3) se dispone una primera junta toroidal (5). Se puede ensamblar sobre una válvula de fondo (1) y un acoplador (2) que cuentan con salientes de acoplamiento (1.1) y (1.2) o en caso de carecer de ellos emplear una brida exterior (10) provista de una segunda junta toroidal (11). También sirve para unir tramos de tubería por medio de una brida central de conexión (12) y sendos grupos de bridas centrales (3) y brida exterior (4).
摘要:
A coupling valve (1) has two parts (2, 3) each having a fluid conduit (5, 21) and a valve closure disc (6, 8). The discs (6, 8) are on shafts (7, 9), each being at is 45° to its respective shaft. The valve discs (6, 8) and their shafts (7, 9) are lined, as are all fluid-contacting surfaces. The discs (6, 8) are configured to press together when the parts (2, 3) are coupled and to move together between closed and open valve positions. The movement is by rotation of one (7) of the shafts as a master shaft, drive being transferred to the other disc (8) by virtue of a friction fit under a compression load applied by a coupling mechanism (15). An O-ring (60) assists the dry seal between the valve discs (6, 8).

A slip fit quick disconnect pipe coupler having an insertion portion and a housing portion which mate to form a sealed coupling between pipes. The coupler uniquely provides positive pipe coupling with extreme ease of disassembly or dis-connection of two pipes. The coupler utilizes a uniquely designed L-shaped tool which allows quick decoupling and easy removal of the separated insertion portion and attached pipes without the need for a plumbing technician to lean or crawl into the space occupied by the coupler.

A tube (1) capable of being coupled, comprising a tube part (2) having a synthetic circumferential wall (3) which is provided, adjacent at least one extremity of the tube part, with a synthetic thickening (5) integrated into the circumferential wall and extending radially outwards with a first clamping surface (6) , further comprising a coupling ring (7) provided at the location of the side of the thickening remote from the extremity so as to be axially slideable around the circumferential wall, which coupling ring is provided with a second clamping surface (8) for cooperation with the first clamping surface. The invention also relates to a method for manufacturing a tube capable of being coupled, wherein a coupling ring is slid around a synthetic circumferential wall of a tube part and wherein, then, on the outer circumference of the circumferential wall, a synthetic thickening is formed for cooperation with a coupling ring.

The invention relates to a seal for medium-conducting components, whereby the components (12, 13) comprise sealing surfaces (20, 25), which are exactly complementary to each other and which are directly pressed together to form a gap-free seal. The contact surfaces (44) between the sealing surfaces is limited to a narrow region directly adjacent to the medium cavity (19). Said gap-free and dead-volume-free seal can be used, for example in germfree, or sterile processes.

A coupling ideally suited for sealing between components such as a fluoropolymer valve body (50) and a fluoropolymer manifold (52) or for coupling tubing end portions, utilizes structure on said components for defining the sealing surfaces. In a preferred embodiment, the coupling comprises a male protruding portion (62), a recessed female receiving portion (64), and a clamping means. The clamping means (92) has an inner threaded surface for engaging a correspondingly threaded portion of the male protruding portion. The male protruding portion is shaped, generally, as a converging rounded conical frustum (65.1) having an exterior surface, a primary sealing surface, a first stop surface (78), a second cooperating stop surface, and a fluid flow duct. The fluid flow duct is preferably concentrically positioned. The recessed portion has a circular perimeter, an inwardly projecting annular ring (74), a first cooperating stop surface, a second stop (82) surface, and a fluid flow duct. The male protruding portion forms a seal by confronting the primary sealing surface and the annular sealing ring.

A coupling assembly includes a pair of glands having ends that seal on opposite faces of a seal member. A coupling nut assembly cooperates with the glands to urge the ends against the seal member. A torque suppression assembly (20, 30, 40) is mounted in a groove (56) of the gland (10) to limit rotational forces from the coupling nut assembly to the gland (10). The torque suppression assembly (20, 30, 40) includes a thrust member (40) that engages the coupling nut assembly and bearing member (20, 30) that transfers axial make-up forces from the thrust member (40) to the gland (10) and rotates relative to the thrust member (40) to reduce torque transfer.

The present invention hose assembly (10) having a distortion limiting wall for creating a dynamic seal comprises a seal (14), a male hose subassembly (12) and a female hose subassembly (16). The seal (14) is concentrically mounted within the female hose subassembly (16) against a radially flanged segment (92) and an extension segment (94) of a female ferrule (74) with a lip (46) of a male ferrule (22) compressing against the seal (14) when the female and male hose subassemblies (16 and 12) are connected together.
