A pipeline temporary blocking device, comprising an upper end cap, a lower end cap, an operating screw and an elastic sealing body, the elastic sealing body is arranged between the upper end cap and the lower end cap, and the lower end cap and the elastic sealing body are located in the engineering pipeline to be sealed Inside, when the operating screw is tightened, the upper end cover is close to the lower end cover, the elastic sealing body presses the inner wall of the engineering pipeline, and the upper end cover is fastened to the nozzle of the engineering pipeline, and is characterized in that: it also includes a dust cover, and the upper end cover is on the inner wall of the engineering pipeline. The nut groove is set, the dust cover is hinged on the notch of the nut groove, the operating screw is tightened, and the elastic sealing body presses the inner wall of the engineering pipeline, the nut of the operating screw is located in the nut groove, and the dust cover is fastened in the nut groove. on the slot. When the operating screw is tightened, the middle part of the sealing body protrudes to the outer periphery and is pressed against the inner wall of the engineering pipeline for sealing. The upper end cover is provided with a nut groove, and the nut of the operating screw is located in the nut groove. It can achieve all-round blocking effect and avoid the corrosion of concrete and water to the operating screw. The elastic sealing body is made of rubber, and the elastic sealing body is drum-shaped, integrally formed, and does not need to be composed of two parts.

The lower end cover is provided with a lower end cover embedded nut, the operating screw rod passes through the elastic sealing body and is screwed with the lower end cover embedded nut, and the lower end cover is provided with an embedded nut, which is more convenient to use.

The inner diameter of the upper end cover is larger than the outer diameter of the nozzle of the engineering pipeline, and the outer diameter of the lower end cover is smaller than the inner diameter of the engineering pipeline.

The utility model has the following advantages:

1. The utility model can effectively prevent concrete, construction waste, etc. from entering the blocked pipeline, reduce the possibility of pipeline blockage, avoid later dredging, and reduce investment costs. The principle structure is simple, the parts are few, and the cost is low.

2. The utility model is easy to install and disassemble, can be installed by one person, only needs a wrench to realize the installation and dismantling, and the dismantling time is short.

3. The maintenance amount of the utility model is very small, and the wear amount of the elastic sealing body only needs to be checked regularly.

5. The utility model is reusable, convenient for storage, and saves investment.
