Abstract
The invention discloses a pipe joint and belongs to the technical field of water heating pipe fittings. The pipe joint comprise two nuts. The two nuts are respectively in a threaded connection with two ends of a pipe sleeve; a sealing sleeve is arranged between the inner wall of each nut and an end head of the pipe sleeve; the inner wall and the outer wall of the sealing sleeve are both provided with a plurality of projections; an annular groove accommodating one end of the sealing sleeve is formed in the inner wall of the nut; the other end of the sealing sleeve extends between the pipe sleeve and the pipe; and the diameter of the sealing sleeve in the pipe sleeve and the pipe is smaller than the diameter of the sealing sleeve in the groove. By the use of the pipe joint, problems of water leakage due to poor connection sealing property of a present pipeline and short service life can be solved.
Description
Technical field
The present invention relates to water heating pipe fittings technical field, especially a kind of joint be connected for two tubes.
Background technique
Pipe coupling is the necessary part that short tube connects into pipeline, what existing pipe coupling adopted is the nut with inner hole thread, to offer at pipeline outer wall the screw thread matched with described nut inner hole screw thread in advance during connection, then make described pipeline be connected with described nut thread, between described pipeline and described nut, be provided with seal ring; But this Placement also exists: sealing is poor, the water capacity in pipeline easily penetrates into screw thread place and causes screw thread rupture or get rusty, and easily leaks, affects the problem in working life.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of pipe coupling, and this pipe coupling can solve existing sealing for tubing joints difference and easily leak, and affects the problem in working life.
In order to solve the problem, the technical solution adopted in the present invention is: this pipe coupling, include nut, described nut is two, these two nuts are threaded with the two ends of pipe box respectively, be provided with stuffing box gland between the termination of described nut inner wall and described pipe box, the inner and outer wall of described stuffing box gland be equipped with multiple anti-skidding projection.
In technique scheme, technological scheme can also be more specifically: described nut inner wall offers the groove of the annular of accommodating stuffing box gland one end, and the described stuffing box gland the other end puts between described pipe box and pipe; The diameter of described stuffing box gland part between described pipe box and pipe is less than it and is positioned at the diameter that described inside grooves divides.
Further: in the middle part of pipe box, to be provided with positioning convex ring.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, because nut is respectively two, and the two ends of pipe box are arranged at respectively; Easy disassembly, improves maintenance efficiency;
2, due to the inner and outer wall of stuffing box gland being equipped with anti-skidding projection; Can improve pipe box, frictional force between pipe and stuffing box gland, what make them bind round each other is tightr, does not depart from;
3, be positioned at because the diameter of stuffing box gland part between pipe box and pipe is less than it diameter that inside grooves divides; Make between medium and screw thread, to there is dual sealing functions, good airproof performance, screw thread can not be caused to rupture or get rusty.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
Pipe coupling shown in Fig. 1, include nut 1, nut 1 is two, these two nuts 1 are respectively by the two ends of thread set at pipe box 3, nut 1 inwall between the termination of pipe box 3 and nut 1 outer end sidewall all offers the groove 11 of annular, all accommodating stuffing box gland 2 one end in groove 11, stuffing box gland 2 the other end all puts between pipe box 3 and pipe 6; The inwall of stuffing box gland 2 is provided with multiple anti-skidding protruding 22, and the outer wall of stuffing box gland 2 is provided with multiple anti-skidding protruding 23, and the diameter of stuffing box gland 2 part 24 between pipe box 3 and pipe 6 is less than the diameter that it is positioned at groove 11 part 21; Positioning convex ring 31 is provided with in the middle part of pipe box 3.The present invention makes to have dual sealing functions between water and screw thread, good airproof performance, and screw thread can not be caused to rupture or get rusty; Not only easy disassembly, improves maintenance efficiency, also improves pipe box, frictional force between pipe and stuffing box gland, and what make them hollow out each other is tightr, does not depart from.
