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 comparatively large, and complicated operation, efficiency of construction is lower.Also have a kind of elasticity plug product used at the one-sided mouth of pipe of pipeline at present on the market, although this product can not damage pipeline configuration, its plugging effect is limited, very easily comes off when bearing pressure or expanding with heat and contract with cold.
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 is easy with dismounting Job Operations, is conducive to the efficiency of construction improving 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, first plug is interconnected by the first occluding body and the first annular lateral retaining plate and forms, in first annular lateral retaining plate, the first sealing gasket is installed, second plug is interconnected by the second occluding body and the second annular side baffle plate and forms, in second annular side baffle plate, the second sealing gasket is installed, first occluding body is connected with one end of connecting rod, connecting rod the other end sidewall arranges outside thread, second occluding body offers screw, and connecting rod and the second occluding body are threaded connection.Connecting rod is installed at least 2 rubber rings, each rubber ring is uniformly distributed along the length direction of connecting rod.The connecting rod of each rubber ring both sides all offers annular slot, in each annular slot, all elastic collar is installed.First occluding body and the second occluding body are quadrangular or hexagon.
The invention has the advantages that: shutoff can be carried out 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 is easy with dismounting Job Operations, is conducive to the efficiency of construction improving pipe plugging operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is using state structural representation of the present invention;
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, first plug 1 is interconnected by the first occluding body 3 and the first annular lateral retaining plate 4 and forms, in first annular lateral retaining plate 4, first sealing gasket 5 is installed, second plug 2 is interconnected by the second occluding body 6 and the second annular side baffle plate 7 and forms, in second annular side baffle plate 7, second sealing gasket 8 is installed, first occluding body 3 is connected with one end of connecting rod 9, connecting rod 9 the other end sidewall arranges outside thread, second occluding body 6 offers screw 10, and connecting rod 9 and the second occluding body 6 are threaded connection.When shutoff is carried out to pipeline, first plug 1 and the second plug 2 are placed in pipe ends respectively, by rotating the second plug 2, the screw 10 in 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, the first sealing gasket 5 and the second sealing gasket 8 play plugging action by line up after mouth of pipe extruding.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 removing shutoff, pipeline can reuse, shutoff is easy with dismounting Job Operations, is conducive to the efficiency of construction improving pipe plugging operation.In addition, compared with current existing one-sided elasticity plug, the present invention is connected by connecting rod 9 due to two ends, in pressure-bearing, the multiple situation such as to expand with heat and contract with cold, all can effectively prevent plug from coming off.
The present invention causes damage through during pipeline to inner-walls of duct in order to prevent connecting rod 9, and can install at least 2 rubber rings 11 on connecting rod 9, each rubber ring 11 is uniformly distributed along the length direction of connecting rod 9.Rubber ring 11 can avoid connecting rod 9 directly to contact inner-walls of duct, prevents inner-walls of duct to be scratched.
The present invention slides on connecting rod 9 to prevent rubber ring 11, can all offer annular slot 12, all install elastic collar 13 in each annular slot 12 on the connecting rod 9 of each rubber ring 11 both sides.The elastic collar 13 of rubber ring 11 both sides can, to rubber ring 11 position-limiting actions, prevent rubber ring 11 from sliding.
The present invention is in order to improve the first sealing gasket 5 and the pressure between the second sealing gasket 8 and the pipe ends mouth of pipe when the first plug 1 and the second plug 2 are rotatably connected, improve the plugging strength of pipeline, first occluding body 3 and the second occluding body 6 all can be made as quadrangular or hexagon, instrument easy to use rotates the second plug 2, this structure is generally used for the pipeline needing permanent shutoff, can make the sealing that pipeline keeps good for a long time.
