Description
Technical field
The present invention relates to a kind of duct closing type device, specifically the detachable plugging device of a kind of pipeline.
Background technique
At present conventional pipe plugging method is by steel plate, steel plug welding envelope, or with expansion bolt plugging, these shutoff modes all can damage pipeline original structure, and the pipeline after shutoff may recover use hardly.And sealing job engineering amount is larger, complicated operation, efficiency of construction is lower.Also have on the market at present a kind of elasticity plug product using at the one-sided mouth of pipe of pipeline, although this product can not damage pipeline configuration, its plugging effect is limited, in the time bearing pressure or expand with heat and contract with cold, very easily comes off.
Summary of the invention
The object of this invention is to provide the detachable plugging device of a kind of pipeline, it can carry out shutoff to pipe ends, and can remove at any time as required, shutoff and demolishing process all can not damage pipeline configuration, after removing shutoff, pipeline can reuse, shutoff and dismounting Job Operations are easy, are conducive to improve the efficiency of construction of pipe plugging operation.
The present invention for achieving the above object, be achieved through the following technical solutions: comprise the first plug and the second plug, the first plug is interconnected and is formed by the first occluding body and the first annular lateral retaining plate, the first sealing gasket is installed in the first annular lateral retaining plate, the second plug is interconnected and is formed by the second occluding body and the second annular side baffle plate, the second sealing gasket is installed in the second annular side baffle plate, the first occluding body is connected with one end of connecting rod, connecting rod the other end sidewall arranges outside thread, in the second occluding body, offer screw, connecting rod and the second occluding body are threaded connection.At least 2 rubber rings are installed on connecting rod, and each rubber ring is uniformly distributed along the length direction of connecting rod.On the connecting rod of each rubber ring both sides, all offer annular slot, elastic collar is all installed in each annular slot.The first occluding body and the second occluding body are quadrangular or hexagon.
The invention has the advantages that: can carry out shutoff to pipe ends, and can remove at any time as required, shutoff and demolishing process all can not damage pipeline configuration, after removing shutoff, pipeline can reuse, shutoff and dismounting Job Operations are easy, are conducive to improve the efficiency of construction of pipe plugging operation.

Fig. 1 is structural representation of the present invention;
Fig. 2 is that the present invention uses status architecture schematic diagram;
Fig. 3 is that the A-A of Fig. 1 analyses and observe structure for amplifying schematic diagram.
Embodiment
The detachable plugging device of pipeline of the present invention comprises the first plug 1 and the second plug 2, the first plug 1 is interconnected and is formed by the first occluding body 3 and the first annular lateral retaining plate 4, interior installation the first sealing gasket 5 of the first annular lateral retaining plate 4, the second plug 2 is interconnected and is formed by the second occluding body 6 and the second annular side baffle plate 7, interior installation the second sealing gasket 8 of the second annular side baffle plate 7, the first occluding body 3 is connected with one end of connecting rod 9, connecting rod 9 the other end sidewalls arrange outside thread, in the second occluding body 6, offer screw 10, connecting rod 9 and the second occluding body 6 are threaded connection.When pipeline is carried out to shutoff, the first plug 1 and the second plug 2 are placed in respectively to pipe ends, by rotating the second plug 2, the screw 10 in the second occluding body 6 is connected with the outside thread of connecting rod 9, until the first plug 1 and the second plug 2 closely cooperate with the mouth of pipe of pipe ends respectively, after the first sealing gasket 5 and the second sealing gasket 8 are subject to mouth of pipe extruding, line up plays plugging action.The present invention can carry out shutoff to pipe ends, and can remove at any time as required, shutoff and demolishing process all can not damage pipeline configuration, and after dismounting shutoff, pipeline can reuse, shutoff and dismounting Job Operations are easy, are conducive to improve the efficiency of construction of pipe plugging operation.In addition, compared with current existing one-sided elasticity plug, the present invention is because two ends connect by connecting rod 9, in pressure-bearing, the multiple situation such as expand with heat and contract with cold, all can effectively prevent that plug from coming off.
The present invention causes damage to inner-walls of duct when preventing connecting rod 9 through pipeline, can at least 2 rubber rings 11 be installed on connecting rod 9, and each rubber ring 11 is uniformly distributed along the length direction of connecting rod 9.Rubber ring 11 can be avoided directly contact inner-walls of duct of connecting rod 9, prevents that inner-walls of duct is scratched.
The present invention slides on connecting rod 9 in order to prevent rubber ring 11, can on the connecting rod 9 of each rubber ring 11 both sides, all offer annular slot 12, the interior elastic collar 13 of all installing of each annular slot 12.The elastic collar 13 of rubber ring 11 both sides can, to 11 position-limiting actions of rubber ring, prevent that rubber ring 11 from sliding.
The present invention in order to improve the pressure between the first sealing gasket 5 and the second sealing gasket 8 and the pipe ends mouth of pipe in the time that the first plug 1 and the second plug 2 are rotatably connected, improve the plugging strength of pipeline, the first occluding body 3 and the second occluding body 6 all can be made as to quadrangular or hexagon, instrument easy to use is rotated the second plug 2, this structure is generally used for needing the pipeline of permanent shutoff, can make the good sealing of the long-term maintenance of pipeline.
