Technical Field
[0001] The utility model relates to the technical field of water supply pipes, in particular to a large-diameter plastic reinforced water supply pipe. Background Art
[0002] Water supply pipes are made of sanitary polyvinyl chloride resin as the main raw material, with appropriate amounts of stabilizers, lubricants, fillers, color enhancers, etc. added, and are extruded by a plastic extruder and injection molded by an injection molding machine. The production of pipes and fittings is completed through processes such as cooling, curing, shaping, inspection, and packaging. They have the advantages of light weight, corrosion resistance, small water flow resistance, energy saving, quick installation, and low cost. Therefore, they are widely used in urban tap water transmission and supply projects, internal and external water supply projects of buildings, water supply projects of industrial and mining enterprises, underground fire protection water supply projects, and farmland water conservancy water transmission and irrigation projects.
[0003] When existing drainage pipes are used for a long time, the water flow quickly reaches its maximum under the action of inertia and produces a destructive effect, reducing the service life of the pipes. In particular, looseness problems are prone to occur at the joints of the pipes, affecting the sealing performance of the pipes. Utility Model Content

[0024] The mounting structure includes a bolt 4 and a nut 5 . The bolt 4 movably passes through the first mounting piece 2 and the second mounting piece 3 . The nut 5 is threadedly sleeved on the outside of the bolt 4 .
[0025] The sealing mechanism comprises a sealing member 6, which is arranged between the first mounting member 2 and the second mounting member 3, and the sealing member 6 is in contact with the inner wall of the pipeline body 1, and the sealing member 6 is connected to the second mounting member 3 via a pushing assembly.
[0026] The sealing member 6 is annular and is an air bag.
[0027] In this embodiment, the interfaces of the two groups of pipe bodies 1 are aligned, and the No. 1 mounting member 2 and the No. 2 mounting member 3 are mounted on the outside of the interfaces of the two groups of pipe bodies 1. With the cooperation of the bolts 4 and the nuts 5, the No. 1 mounting member 2 and the No. 2 mounting member 3 can be fixed to the outside of the pipe body 1. The sealing member 6 is located inside the pipe body 1 and contacts the inner walls of the two groups of pipe bodies 1, which can seal the connection between the two groups of pipe bodies 1 and is beneficial to increase the sealing of the two groups of pipe bodies 1.

[0030] To sum up the above, when water flows through the connection between the two groups of pipe bodies 1, since the end of the push plate 10 away from the pipe body 1 is inclined, the water can drive the push block 7 to move through the push plate 10, and the push block 7 moves outside the slide rod 9 in the direction away from the fixing member 8. The push block 7 can squeeze the seal 6 to further increase the sealing of the connection between the two groups of pipe bodies 1. At this time, the spring 11 is deformed by the force. When the effect of the water flow on the push plate 10 is reduced, the spring 11 can drive the push block 7 to reset under the elastic action of the spring 11.
