摘要： A hydraulic flange connection (10) having a formed tube (12) in physical conjointness with a contoured sleeve member (14), the conjointness including the sleeve member (14) having a cylindrical body bore (24), a cylindrical outer portion (26) tapering at one axial end into a frustoconical portion (30) abutting one bore end (32), the cylindrical outer portion (26) also merging into an annular outer end surface (36) having at least one circular edge (38) defining a bowl-shaped recess (42) with a raised annular inner end surface (46); the tube having a cylindrical portion (13) extending into and through the sleeve member bore (24), a radial flange portion (54) thereof including an axially outwardly-directed, openly curved, circumferential radial groove (60), with an inner surface (56) of the flange portion (54) conforming axially and radially with an abutting complementary surface (43) of the bowl-shaped outer recess (42) in a fully nesting retention relationship. Details of achieving the conjointness between the tube (12) and the sleeve member (14) are also set forth in product-by-process claim recitation.

摘要： The inventive pipe connecting device comprises a threaded fitting (2), a coupling nut (3) screwed thereon and a retaining ring (6) provided with a through orifice (12) for the passage of a pipe (1) is disposed between the coupling nut and the connection end of said pipe (1). The connection end of the pipe (1) is provided with a flange collar (7) and the retaining ring (6) is provided with a contact surface (14) for the coupling nut (3). Said invention is characterised in that an internal conical section (13) is formed at the end of the through orifice (12) of the retaining ring (6) oriented towards the flange collar (7), the diameter of said section increases away from the internal diameter of said orifice (12) along a determined length to the end of the orifice and an external conical section (11) is formed on the periphery of the pipe, extends along a determined length to the flange collar (7) and has an increasing diameter, wherein the dimensions and the cone angle of said section are adapted to the dimensions and cone angle of the internal conical section.

摘要： Die Erfindung betrifft eine druckfeste und formschlüssige Rohrverbindung, mit umgeformtem Rohr, einem Verschraubungskörper mit einem Innenkonus und einer Überwurfmutter, wobei das umgeformte, mit einer Wulst versehene Rohr ein entsprechend der Tiefe des Konus achsparalleles Endstück aufweist, dem sich eine radial verlaufende Anschlagringfläche anschließt, welche im montierten Zustand der Rohrverbindung an der Stirnfläche des Rohrverbindungsstutzens vollständig zur Anlage kommt, und zwischen dem Konus, dem achsparallelen Endstück des Rohres und der radial verlaufenden Anschlagringsfläche ein Dichtungsring angeordnet ist. Zwischen der Überwurfmutter (2) und dem umgeformten, mit einer Wulst versehenen Rohr (3) sowie einem Teil des achsparallelen Rohres (3) ist eine Stützhülse (5) angeordnet, welche mit den genannten Rohrabschnitten eine Anlagefläche (17) bildet. Der Teil der Rohrverformung, der sich vor dem Übergang zum unverformten Rohr (3) befindet, bildet mit der Stützhülse (5) eine Anlagefläche (9), welche zur Rohrachse einen Winkel zwischen 15° - 40° aufweist.

摘要： A fitting to interconnect water pipes or to connect pipes with valves or mountings. The connector housing has an O-ring seat, constituting two walls of a groove for an O-ring. The fitting comprises a clamping sleeve, having a first end provided with a flange, which forms a third wall of the O-ring seat groove. The flange is retained against the coupling housing by a nut screwed by hand onto outer threads on the coupling housing. The clamping sleeve is adapted to be clamped against a pipe which is inserted into the clamping sleeve, and the O-ring seals against the outer surface of the pipe.

摘要： A pipe joint structure is used to prevent a tube (18) and pipe joint (2), especially fluororesin pipe joint from slipping off. The said pipe joint comprises of a joint body (20), a fixed ring (27) and a union nut (26), being assembled by passing the tube end through said union nut and then though the fixed ring within the union nut. A jig is then used to expand said tube end to become a flared end (180) consisting of a conical surface (181) and a tubular surface (182), and finally connect it to the conical surface and tubular surface on top of the tube connecting portion of said joint body. When said union nut is fastened to the locking thread of said tube connecting portion, its interior recess portion will couple with the bulging surface of fixed ring to ensure it to stay in a concentric position, thereby allowing the tube wall of sealed surface to be compressed evenly and secured firmly on said pipe joint so to achieve a seal and prevent it from slipping off.
