Problems solved by technology

At present, PVC drainage pipes are widely used. With the development of economic construction, the floors of modern buildings are getting higher and higher, and people's living standards are gradually improving. However, for high-rise drainage pipes, due to the higher floors, the noise generated in the drainage pipes It is also getting bigger and bigger, which has added a lot of troubles to people. The temperature in this winter is low, and the water flow in the water pipe is easy to freeze, which can not bring inconvenience to people.

Embodiment

[0021] Such as Figure 1-4 As shown, the embodiment of the present invention is a PVC water pipe, including an inner pipe 3, an outer pipe 1 and a honeycomb sandwich core 2, the inner pipe 3 and the outer pipe 1 are coaxially arranged, and the honeycomb sandwich core 2 is arranged inside Space between tube 3 and outer tube 1.

[0022] The thickness of the honeycomb sandwich 2 of the present embodiment is 0.5cm, and the honeycomb sandwich 2 is made up of a series of regular hexagonal cells, and the side length of the regular hexagonal cells of the honeycomb sandwich 2 is 1cm, and the regular hexagonal cells of the honeycomb sandwich 2 The polygonal cells are filled with foam powder, which is good for heat preservation and can also isolate the noise generated by the flowing water in the water pipes.

[0023] The inner wall of the inner pipe 3 of the present embodiment is provided with a spiral groove 4, the groove width and depth are 0.5cm, and the helical angle of the spiral g...

Abstract

A polyvinyl chloride (PVC) water pipe comprises an inner pipe, an outer pipe and a honeycomb core, wherein the inner pipe and the outer pipe are coaxially arranged, the honeycomb core is arranged in space between the inner pipe and the outer pipe, a spiral groove is formed in the inner wall of the inner pipe, the honeycomb core is composed of a series of polygonal hole grids, and the polygonal hole grids of the honeycomb core are filled with foam. The PVC water pipe is good in intensity, low in noise, and meanwhile good in heat preservation effect.

Description

technical field [0001] The invention relates to the field of pipelines, in particular to a PVC water pipe. Background technique [0002] Drainage pipes play an important role in daily life. Drinking water, daily sewage, rainwater utilization, etc. are all supplied or discharged through drainpipes. Compared with cast iron drainage pipes which are not resistant to corrosion, stainless steel drainage pipes have high cost and difficult transportation. Plastic drainage pipes have the advantages of low cost, convenient transportation and stable performance, and have been more and more used in the field of drainage pipes. At present, PVC drainage pipes are widely used. With the development of economic construction, the floors of modern buildings are getting higher and higher, and people's living standards are gradually improving. However, for high-rise drainage pipes, due to the higher floors, the noise generated in the drainage pipes It is also getting bigger and bigger, which ad...
