초록 ▼

A locking and nonseal pipe joint device which is comprised of a flanged holder having an external thread and adapted at its one end to be secured to a base body and at its opposite end to hold an end of the pipe, an intermediate packing member for sealing and locking the joint and a locking member having an internal thread and adapted to be screwed onto the flanged body through the intermediate packing member. The intermediate packing member is compressed against a circumference of the pipe in accordance with the screwing operation of the locking member.

A conduit coupling device comprising in combination: a conduit-supporting member having first and second externally threaded portions and a laterally extending flange therebetween protruding therebeyond, said member having a central aperture dimensioned to receive and support a conduit, said member having an inwardly directed internal shoulder adapted to limit the extent of insertion into said member of said conduit and an inclined radial shoulder extending to said central aperture; an intermediate packing member having a central aperture extending therethrough of substantially the same diameter as said central aperture of said conduit-supporting member, said packing member having on at least a portion of its outer circumference threads of substantially the same diameter and pitch as the threads on at least one of said threaded portions of said conduit-supporting member, both ends of said packing member having an inclined surface, a first of said inclined surfaces being complementary to and adapted to coact with the inclined radial shoulder of said conduit-supporting member upon assembly of the device; and a locking member having a first section provided with a central through aperture of substantially the same diameter as that of the central aperture of said conduit-supporting member and said packing member and a second section threaded internally with a thread diameter and pitch adapted to cooperate with the threads of said packing member and the threads on said one portion of said conduit-supporting member, said first and second sections of said locking member being connected internally by an inclined surface extending between said internal thread and said central aperture which is engageable upon assembly with said packing member and conduit-supporting member with the other of said inclined surfaces of said packing member; said locking member, packing member and conduit-supporting members being positionable such that with their central apertures in alignment said locking member is threadable onto both of said conduit-supporting and packing members so as to impart longitudinal and inwardly directed radial forces on said packing member at both ends thereof whereby substantially the entire internal surface of said packing member engges the external surface of the conduit to thereby lock said conduit against longitudinal movement and simultaneously seal the joint formed between said conduit and coupling against leakage of fluid from said conduit.
