Abstract
The present invention relates to a kind of plugging device, including rubber disc chock plug, the centre of the rubber disc is provided with through hole, the rubber disc both sides are equipped with circular groove, uniform annular is distributed with the jacking block matched with its inwall in the groove, also annular is uniformly embedded with the contiguous block matched with its inwall in the through hole, is coupled together by elastic component between the jacking block and the contiguous block；The tapered setting of chock plug, external screw thread is provided with the outer wall of the chock plug, and the inwall of the contiguous block is provided with the internal thread matched with the external screw thread, and the rubber disc can be strutted in the chock plug screw-in contiguous block makes it be close to inner-walls of duct realization closure.The beneficial effects of the invention are as follows：Can rapidly be installed in the pipeline for needing to block, it is convenient to dismount, improve operating efficiency.
Description
Technical field
The present invention relates to pipe fitting, and in particular to a kind of water pipe block head.
Background technology
, it is necessary to be blocked to pipeline before the related work such as pipeline maintenance or increase branch road, now
Need to use block head.Existing block head will be sealed due to complex structure, it is necessary to take a long time to
Plug is got lodged in pipeline, and poor sealing, usually it also occur that leakage phenomenon.
The content of the invention
In sum, to overcome the deficiencies in the prior art, the technical problems to be solved by the invention to be to provide
The technical scheme that the present invention solves above-mentioned technical problem is as follows：A kind of plugging device, including plantation rubber
Disk chock plug, the centre of the rubber disc is provided with through hole, and the rubber disc both sides are equipped with circular groove,
Uniform annular is distributed with the jacking block matched with its inwall, the through hole also annular equal in the groove
It is even to be embedded with the contiguous block matched with its inwall, elastic component is passed through between the jacking block and the contiguous block
Couple together；
The tapered setting of chock plug, external screw thread is provided with the outer wall of the chock plug, the contiguous block it is interior
Wall is provided with the internal thread matched with the external screw thread, and the chock plug is screwed in the contiguous block and can strut institute
Stating rubber disc makes it be close to inner-walls of duct realization closure.
Further, the elastic component is spring.
Further, the jacking block is in circular arc strip.
Further, the contiguous block is in circular arc strip.
The beneficial effects of the invention are as follows：Can be installed to rapidly in the pipeline for needing to block, it is convenient to dismount,
Improve operating efficiency.
Brief description of the drawings
Fig. 1 is top view of the invention；
Fig. 2 is the A-A sectional views of Fig. 1；
Fig. 3 is the schematic diagram of chock plug.
In accompanying drawing, the list of parts representated by each label is as follows：
1st, rubber disc, 2, chock plug, 3, through hole, 4, jacking block, 5, contiguous block, 6, elastic component.
Specific embodiment
Principle of the invention and feature are described below in conjunction with accompanying drawing, example is served only for explaining this
Invention, is not intended to limit the scope of the present invention.
As Figure 1-3, a kind of plugging device, including rubber disc 1 and chock plug 2, the plantation rubber
The centre of disk 1 is provided with through hole 3, and the both sides of the rubber disc 1 are equipped with circular groove, in the groove
Interior uniform annular is distributed with the jacking block 4 matched with its inwall, preferably：The jacking block 4 is in circular arc bar
Shape.Also annular is uniformly embedded with the contiguous block 5 matched with its inwall in the through hole 3, preferably：
The contiguous block 5 is in circular arc strip.Connected by elastic component 6 between the jacking block 4 and the contiguous block 5
Pick up and, preferably：The elastic component 6 is spring.
The tapered setting of the chock plug 2, external screw thread, the contiguous block are provided with the outer wall of the chock plug 2
5 inwall is provided with the internal thread matched with the external screw thread, and the chock plug 2 is screwed in the contiguous block 5
The rubber disc 1 can be strutted makes it be close to inner-walls of duct realization closure.
When needing blocking pipe, plugging device is put into pipeline, then is screwed between the contiguous block 5
Chock plug 2, because chock plug 2 is set in certain taper, with the lasting screw-in of chock plug 2, chock plug can be supportted
Contiguous block 5 is opened, the compression elastic piece 6 of contiguous block 5 for making, so that outwards support block 4, final rubber disc
1 is softened change greatly, and the outer wall of rubber disc 1 is close to inner-walls of duct, realizes the closure of pipeline.Removal
When plugging device, chock plug 5 is screwed off.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in the present invention
Spirit and principle within, any modification, equivalent substitution and improvements made etc. should be included in this hair
Within bright protection domain.
