Description
Technical field
The utility model relates to hot-water heating field, particularly a kind of plug and water heating pipe fittings.
Background technique
Plug, for the end of pipeline, prevents the leakage of pipeline, plays the effect of sealing, is conventional pipe fitting during water heating system is installed.The plug generally using is at present being to be wound around in the above raw meal belt or to put O RunddichtringO on band ear plug to reach leakage-proof effect.More traditional, time-consuming by the method that is wound around raw meal belt, effort again, but also can, because of builder's technological disparity, often not reach desirable effect, and once suppress examination, 80% there will be weeping, customer complaint is many, also affects reputation.With O type circle, in the time of construction, usually can be because overexerting, cause O type circle displacement distortion, matching gap is large, thereby does not reach the effect of sealing leak-stopping.In the time suppressing examination, because hydraulic pressure is larger, O type circle can be ejected to original position simultaneously, cannot be spacing, produce displacement, cause pipeline to leak air, leak, thereby make to suppress failure, need to repeatedly do over again and can reach Acceptance level, affect efficiency, and make troubles to construction.
Model utility content
The purpose of this utility model is to have overcome above-mentioned defect, and a kind of plug and water heating pipe fittings of good sealing effect is provided.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of plug, described plug one end is hexagonal cylindrical body, and the other end is that outside is provided with externally threaded cylindrical body, and described cylindrical body end is provided with the seal groove of ring-type, in described seal groove, is provided with seal ring.
Further, described seal groove width is less than described seal ring thickness.
Further, described plug side is provided with annular projection.
Further, center, described plug hexagonal cylindrical body one end is provided with hexagonal hole.
The beneficial effects of the utility model are: on plug, have seal groove, it is spacing that installation seal ring can play position-limiting action, prevents seal ring displacement.
In order to solve the problems of the technologies described above, another technological scheme that the utility model adopts is:
A kind of water heating pipe fittings, the pipe joint that comprises plug and match with described plug, described plug one end is hexagonal cylindrical body, the other end is that outside is provided with externally threaded cylindrical body, described cylindrical body end is provided with the seal groove of ring-type, in described seal groove, is provided with seal ring, and described pipe joint is cylinder, described pipe joint inwall is provided with tapped shoulder hole, and described pipe joint is connected with externally threaded cooperation by internal thread with cylindrical body one end of plug.
Further, described seal groove width is less than described seal ring thickness.
Further, the aperture of described shoulder hole is greater than the external diameter of described annular seal ring.
Further, described plug side is provided with annular projection.
Further, center, described plug hexagonal cylindrical body one end is provided with hexagonal hole.
The beneficial effects of the utility model are: on plug, have seal groove, seal ring is installed, can save the raw meal belt time used that is wound around, when installation, fix because seal ring has seal groove, be threaded into, and play seal action, because the side that adopts seal ring seals, and have seal groove spacing, can prevent seal ring displacement, one installs to position, facilitate, save time, good airproof performance, and the life-span is high.

Label declaration:
1, plug; 2, pipe joint; 11, outside thread; 12, seal groove; 13, seal ring; 14, projection; 15, hexagonal hole; 21, shoulder hole; 211, internal thread.
Embodiment
By describing technology contents of the present utility model, structure characteristics in detail, being realized object and effect, below in conjunction with mode of execution and coordinate accompanying drawing to be explained in detail.
The design of the utility model most critical is: on plug, have seal groove, seal ring is installed, can save the raw meal belt time used that is wound around, when installation, fix because seal ring has seal groove, be threaded into, and play seal action, because the side that adopts seal ring seals, and have seal groove spacing, can prevent seal ring displacement, one installs to position, facilitate, save time, good airproof performance, and the life-span is high.
Refer to Fig. 1 and Fig. 2, a kind of water heating pipe fittings, the pipe joint 2 that comprises plug 1 and match with described plug 1, described plug 1 one end is hexagonal cylindrical body, the other end is the cylindrical body that outside is provided with outside thread 11, described cylindrical body end is provided with the seal groove 12 of ring-type, in described seal groove 12, be provided with seal ring 13, described pipe joint 2 is cylinder, described pipe joint inwall is provided with the shoulder hole 21 with internal thread 211, and described pipe joint 2 is connected with the cooperation of outside thread 11 by internal thread 211 with cylindrical body one end of plug 1.
Working principle of the present utility model is:
When installation, adopt spanner that plug 1 is fixed in pipe joint 2, because seal ring 13 has seal groove 12 fixing, be threaded into, and play seal action, because the side that adopts seal ring 13 seals.
From foregoing description, the beneficial effects of the utility model are: on plug 1, have seal groove 12, seal ring 13 is installed, can save and be wound around the raw meal belt time used, when installation, because seal ring 13 has seal groove 12 fixing, be threaded into, and play seal action, because the side that adopts seal ring 13 seals, and there is seal groove 12 spacing, can prevent that seal ring 13 is shifted, one installs to position, facilitate, save time, good airproof performance, and the life-span is high.
Further, described seal groove 12 width are less than described seal ring 13 thickness, adopt Spielpassung, prevent that seal ring 13 is excessive and cannot pack seal groove 12 into.
Further, the aperture of described shoulder hole 21 is greater than the external diameter of described annular seal ring 13, adopts Spielpassung, prevents that seal ring 13 is excessive and cannot pack shoulder hole 21 into.
Further, described plug side is provided with annular projection 14, plays position-limiting action in the time that plug is installed.
Further, center, described plug hexagonal cylindrical body one end is provided with hexagonal hole 15, also can adopt inner hexagon spanner that plug 1 is installed in the situation that lacking common wrench.
In sum, on the plug that the utility model provides, there is seal groove, installation seal ring, can save the raw meal belt time used that is wound around, when installation, fix because seal ring has seal groove, be threaded into, and play seal action, because the side that adopts seal ring seals, and there is seal groove spacing, can prevent seal ring displacement, one installs to position, facilitate, save time, good airproof performance, and the life-span is high, in plug, many places adopt Spielpassung, increase interchangeability, when installation, can adopt spanner also can adopt inner hexagon spanner.
