According to the utility model, a pipeline can be tightly stopped, and the pipeline sealing stopper is firm and reliable, is convenient to disassemble, assemble and operate, is suitable for stopping during large and small pipeline construction, can improve the construction quality, and has an antitheft function.
Description
Technical field
The utility model relates to the interim blocking technology of construction pipeline mouth, particularly is a kind of pipeline plugging device.
Background technique
In the pipeline construction process, as not constructing continuously, its pipeline mouth is wanted interim shutoff.The weldering one interim blind plate that has slices off with air gun during construction again, increases post workman's workload.Otherwise pipeline gets into impurity easily, influences the pipeline construction quality, can not satisfy construction requirement, influences ordinary production.
Summary of the invention
The purpose of the utility model is exactly to above-mentioned deficiency, designs a kind of pipeline plugging device.
The purpose of the utility model is realized by following technical proposals:
The utility model comprises: capping, interior side's wrench, hinge, support, support claw, center-pole, silk braid.It is characterized in that: the capping outer periphery of described pipeline plugging device is an arc; Inner periphery is the flange disc structure, and the center is provided with circular shrinkage hole, and center-pole passes from shrinkage pool; Be installed in the shrinkage pool with interior side's wrench of center-pole one, center-pole is provided with outside thread and cooperates with silk braid; Be respectively equipped with at least two hinges around shrinkage pool, the silk braid, the support claw that has square waveform is provided with two hinges, by supporting capping, support claw, silk braid is connected.
The beneficial effect of the utility model is: the shutoff of pipeline mouth is tight, and is solid and reliable, and dismounting is easy to operate, is applicable to big or small pipeline construction shutoff, improves construction quality, and has the antitheft effect.
Description of drawings
Accompanying drawing is that the utility model master looks the broken section structural representation.
In the accompanying drawing, 1. capping, 2. shrinkage pool, 3. in square wrench, 4. hinge 5. supports, 6. support claw, 7. center-pole, 8. silk braid.
Embodiment
Below in conjunction with accompanying drawing further elaboration is done in the enforcement of the utility model:
The utility model is by capping 1, interior side's wrench 3, hinge 4, support 5, support claw 6, and center-pole 7, silk braid 8 are formed.Capping 1 outer periphery of its pipeline plugging device is an arc, and inner periphery is the flange disc structure, and the center is provided with circular shrinkage hole 2, and center-pole 7 passes from shrinkage pool 2, is installed in the shrinkage pool 2 with interior side's wrench 3 of center-pole 7 one, and center-pole 4 is provided with outside thread and cooperates with silk braid 8; Be respectively equipped with at least two hinges 4 around shrinkage pool 2, the silk braid 8, the support claw 6 that has square waveform is provided with two hinges, by supporting 5 with capping 1, support claw 6, silk braid 8 connections.Cooperate special spanner with interior side's wrench 3 of center-pole 7 during use, the center-pole 7 that turns clockwise supports 5 and shrinks, and support claw 6 stretching pipeline inwalls make capping 1 seal the pipeline mouth; Be rotated counterclockwise center-pole 7, can take off the pipeline plugging device.
