Abstract
The utility model discloses a pressure-resistant sealing connecting structure for pipe, comprising a connecting piece, a sealing ring, a pressure-resistant sleeve, a nut and a pipe. In the big-end chamber of the circle-type connecting piece, a sealing piece and the pressure-resistant sleeve are inserted; an outside thread of the connecting piece is matched with the nut whose front end is provided with a thread and the back end is a conical surface. The utility model is widely used for the connection of the pipe of a pipeline; on the top of the outerwall of the pipe, according to priority, an internal-thread nut, the pressure-resistant sleeve and the sealing ring are sheathed, and then the sheathed pipe is inserted into the chamber of the connecting piece of the pipe; the internal-thread nut aims at the outside thread of the connecting piece of the pipe and screws tightly with the outside thread of the connecting piece of the pipe. The utility model has the characteristics of good pressure-resistance and sealing property, uneasy leakage, simple structure, convenience in mounting and dismounting pipeline and obvious economic benefit.
Description
Technical field
The utility model relates to a kind of pipe pressure-resistant seal linkage structure device, especially utilizes the internal threaded nut rotation to advance roof pressure cover, seal ring roof pressure sealing pipe are connected and fixed effect.
Technical background
At present, the sealing of pipe grafting O type circle is all adopted in known pipe connection, special vice clamp locking structure, the accuracy of manufacturing of this pipe and joint and construction and installation aspect technology all have high requirements, cause joint seepage to occur easily as running into vibration, can cause very large economic loss because of some reason or pipe.
Summary of the invention
In order to overcome existing pipe connection is to adopt the sealing of pipe grafting O type circle, the technical deficiency of special vice clamp locking structure, the utility model provides a kind of pipe pressure-resistant seal linkage structure, this pipe pressure-resistant seal linkage structure is to adopt plug-in type to connect, pressure-resistant seal performance excellence, simple in structure, mounting or dismounting pipeline convenience.
The purpose of this utility model provides a kind of pipe pressure-resistant seal linkage structure, in the major part inner chamber of round link, embed Sealing, the roof pressure cover, the outside thread of link and front end band internal thread rear end are that the nut of the conical surface is complementary, described tube outer wall top packs into internal threaded nut in order earlier, the roof pressure cover, behind the seal ring, in the pipe insertion tube sub-connecting member inner chamber that encapsulation is good, and screw by internal threaded nut alignment tube sub-connecting member outside thread, the inner conical surface of nut and roof pressure cover petal top end rubbing contact at first in the process of tightening, force roof pressure interplanting axial displacement, and the roof pressure seal ring makes seal ring produce the expansion of axial compression warp-wise, at the pipe connection inner chamber, the Seal cage that the roof pressure end face of tube outer wall and roof pressure cover is formed fills up compacting, make it to form good pressure-resistant seal state, this moment, seal ring will stop the axial displacement of roof pressure cover gradually, roof pressure cover petal is top just under the effect of nut inner conical surface warp-wise component in the case, force the compressing tube wall to produce distortion and finally make the several warp-wise pits of formation on the tube wall, make top being locked in the pipe pit of petal play fixation.
The beneficial effects of the utility model are pressure-resistant seal performance excellences, not easy to leak, simple in structure, the mounting or dismounting pipeline is convenient, economic benefit is obvious.
Description of drawings:
Fig. 1 is a structural drawing of the present utility model
Fig. 2 is the figure of being used to complete of the present utility model
Fig. 3 is a roof pressure cover plan view of the present utility model
Link in the drawings, 1; 2, seal ring; 3, roof pressure cover; 4, nut; 5, pipe; 6, roof pressure cover petal point.
Specific embodiment:
At Fig. 1, in 2, nut (4) roof pressure cover (3) seal ring (2) packs into pipe (5) and connects the termination, with pipe (5) termination that connects, seal ring (2), in roof pressure cover (3) insertion tube sub-connecting member (1) inner chamber, again nut (4) internal thread and link (1) outside thread are screwed, along with tightening of nut (4) urges roof pressure cover (3), roof pressure cover this moment (3) has made the good pressure-resistant seal state of formation between pipe (5) and link (1) under the effect of axial roof pressure power, at this moment roof pressure cover (3) petal point can be forced pipe (5) outer wall is pressed into several warp-wise pits, to play the effect that locking connects pipe.
Claims (2)
1, a kind of pipe pressure-resistant seal linkage structure, comprise link, seal ring, roof pressure cover, nut, pipe, it is characterized in that in the major part inner chamber of round link that embed Sealing, roof pressure cover, the outside thread of link and front end band internal thread rear end are that the nut of the conical surface is complementary.
2, according to the described a kind of pipe pressure-resistant seal linkage structure of claim 1, it is characterized in that roof pressure overlaps top petal shape.
