When in use, the two pipe end plugging plates 2 are respectively installed on the two ports of the pipe 1, and the two ports are divided into upstream and downstream, and the water pressure test should be carried out at the upstream position. An entry hole 3 is opened at one end of the pipe end plugging plate 2, and a flange 4 is provided at one end of the pipe end plugging plate 2. The internal thread of the flange 4 is penetrated by a connecting bolt 6 for fixing the entry hole blind plate 5. Through the entry hole 3, personnel can enter the interior of the pipe 1 to perform operations such as grinding and cleaning the inner wall of the pipe, so as to reduce the occurrence of gaps when the interface is connected later.

[0022] An injection and drainage pipe 7 is fixedly installed at the bottom of the surface of the two pipe end plugging plates 2, and an injection and drainage control valve 8 is provided on the surface of the injection and drainage pipe 7. A connecting pipe 9 is fixedly installed on the top of the surface of one of the pipe end plugging plates 2, and an experimental control valve 10 is provided on the surface of the connecting pipe 9. Open the injection and drainage control valve 8 and the experimental control valve 10 to inject water into the equipment until water comes out of the connecting pipe 9, and then close the injection and drainage control valve 8 and the experimental control valve 10.

[0023] One end of the connecting pipe 9 is fixedly connected to a flange joint 11, and a water pressure test pipe 13 is fixedly installed on the flange joint 11 through an assembly bolt 12. After the water is filled into the equipment, the water pressure test pipe 13 is connected through the flange joint 11, and the experimental control valve 10 is opened casually to continuously replenish water into the equipment and maintain a water column pressure of 2m.

The steps and gaps between the pipe 1 and the pipe end plugging plate 2 are filled with glass glue to make the interface smooth. After removing the debris, resin glue is applied in layers at the junction of the pipe 1 and the pipe end plugging plate 2 and glass fiber cloth 14 is laid to make it bonded. , after solidification, open the injection and drainage control valve 8 and the experimental control valve 10 to inject water into the equipment until water comes out of the connecting pipe 9, then close the injection and drainage control valve 8 and the experimental control valve 10. After the water is injected into the equipment, connect the water pressure test pipe 13 through the flange joint 11, and open the experimental control valve 10 to continuously replenish water in the equipment and maintain a water column pressure of 2m.
