Water supply pipe with built-in thermal-insulation layer

Abstract

The invention discloses a water supply pipe with a built-in thermal-insulation layer, and is designed by mainly aiming at the problems of high cooling speed and large possibility of being frozen and blocked of the traditional water supply pipe, especially the water supply pipe for a water heater. The water supply pipe with the built-in thermal-insulation layer mainly comprises an inner plastic layer, an outer plastic layer and a thermal-insulation layer and is characterized in that the inner plastic layer and the outer plastic layer are both made of PVC (polyvinyl chloride) or PE (polyethylene); the thermal-insulation layer is made of cotton thread; multiple cotton threads of the thermal-insulation layer can be used according to the requirement of the pipe diameter and are spirally wound on the inner thermal-insulation layer; and the outer thermal-insulation layer is arranged out of the cotton threads of the thermal-insulation layer by hot pressing. The water supply pipe with the built-in thermal-insulation layer, which is provided by the invention, keeps the advantages of the traditional water supply pipe and has the advantages of strong toughness and strength, low cost and convenience in manufacture, the temperature of flowing hot water can be prevented from easily losing, and the inner hot water is prevented from being frozen by outer cold.

Description

technical field [0001] The invention relates to a temperature-insulated water supply pipe, in particular to a water supply pipe with a built-in temperature-insulation layer. Background technique [0002] With the continuous improvement of living standards, almost 90℅ of families have bathing facilities, and bathing has brought great comfort and convenience to people's lives. As far as the current situation is concerned, the water supply pipes as one of the elements of bathing facilities are mostly aluminum-plastic pipes, or plastic pipes. The water pipe with this structure has a certain strength and is not easy to be bent and blocked, which ensures the smooth flow of water. But whether it is a plastic pipe or an aluminum-plastic pipe, there are some shortcomings. Solar water heaters are mostly placed outdoors in sunny places, where there is both wind and sun, severe winter heat, freezing and raining. These uncertain factors have caused the exposed water pipes to age premat...
