Description

Technical Field

[0001] The utility model relates to the technical field of water supply pipes, and more specifically to a wear-resistant PE water supply pipe. Background Art

[0002] PE water pipe, also known as polyethylene water pipe, is a plastic water pipe made of polyethylene resin as the main raw material and is made by extrusion molding. Compared with traditional metal pipes, PE water pipes are light in weight, corrosion-resistant, and not easy to scale. They can effectively avoid water pollution and ensure water safety. At the same time, its production process is pollution-free and the materials can be recycled, which reduces the difficulty of waste treatment and environmental pollution risk.

[0003] In the existing technology, PE water supply pipes are usually connected by hot melting. The ends of the two PE pipes are heated by a hot melt machine. After the two PE pipe ends are melted, the hot melt machine is removed and the hot melt surfaces of the two PE pipes are bonded together. However, after the PE pipe is hot-melted, its connection end is relatively fragile. After the PE pipe is buried in the soil, the internal water flows under pressure, causing the PE pipe to shake. The shaking hot melt end of the PE pipe will rub against the soil, causing wear on the hot melt end of the PE pipe, which can easily cause pipe leakage. For this reason, we propose a wear-resistant PE water supply pipe. Utility Model Content

[0004] Based on the above-mentioned technical problem that "after the PE pipe in the prior art is buried in the soil, the internal water flows under pressure, causing the PE pipe to shake, and the shaking hot-melt end of the PE pipe will rub against the soil, causing wear on the hot-melt end of the PE pipe, which can easily cause pipe leakage", the utility model proposes a wear-resistant PE water supply pipe.

[0005] The utility model proposes a wear-resistant PE water supply pipe, comprising a PE water supply pipe, wherein the circumferential outer wall of the PE water supply pipe is sleeved with a first sheath and a second sheath, the first sheath and the second sheath are rotatably connected, the end of the first sheath is fixedly connected with a second fixing block, the outer wall of the second sheath is fixedly connected with a first fixing block, the top of the first fixing block is fixedly connected with a threaded rod, the top of the second fixing block is provided with a connecting groove, the top of the threaded rod passes through the connecting groove and extends to the outside thereof, the circumferential outer wall of the threaded rod is threadedly connected with a hexagonal nut, and the bottom of the hexagonal nut is in extrusion contact with the top of the second fixing block.

[0006] Preferably, the outer wall of the first sleeve is fixedly connected to a first connection block, the outer wall of the second sleeve is fixedly connected to a second connection block, the inner wall of the first connection block is rotatably connected to a rotating shaft, and the rotating shaft is rotatably connected to the second connection block.

[0008] Preferably, a sealing ring is sleeved on the outer wall of the threaded rod, the sealing ring is sleeved inside the sealing groove, and the inner wall of the groove is in compression contact with the sealing ring.

[0009] Preferably, the ends of the first and second sheaths are each provided with a plurality of installation grooves, and limiting grooves are respectively provided on both sides of the inner walls of the plurality of installation grooves, the inner walls of the plurality of limiting grooves are each fixedly connected with a connecting rod, and the circumferential outer walls of the plurality of connecting rods are each sleeved with a spring.

[0011] Preferably, one end of the spring is fixedly connected to the connecting plate, and the other end of the spring is fixedly connected to the inner wall of the limiting groove.

[0012] The beneficial effects of the present invention are:

[0013] 1. By buckling the first sheath and the second sheath together, the first sheath and the second sheath can fully squeeze the outer wall of the PE water supply pipe, so that the first sheath and the second sheath can be fixed to the hot-melt end of the PE water supply pipe, thereby avoiding friction between the PE water supply pipe and the soil and improving the wear resistance of the PE water supply pipe.

[0014] 2. By respectively putting the first sheath and the second sheath on the PE water supply pipe, and sliding the first sheath and the second sheath along the PE water supply pipe, multiple rollers on the first sheath and the second sheath roll along the outer wall of the PE water supply pipe, thereby facilitating the movement of the first sheath and the second sheath and reducing the friction between the first sheath and the second sheath and the PE water supply pipe.
