Heat preservation water pipe

Abstract

The invention discloses a heat preservation water pipe. The heat preservation water pipe is characterized by comprising a water pipe (1), a heat preservation pipe (2), a leakage-proof layer (3), a heat preservation layer (4) and a shielding layer (5) which are located at the center. The heat preservation pipe (2) is arranged in the axial direction of the water pipe (1) in a wavy mode, provided with a liquid inlet (6) and a liquid outlet and wrapped by the leakage-proof layer (3) tightly, the leakage-proof layer (3) is wrapped by the heat preservation layer (4) tightly, and the heat preservation layer (4) is wrapped by the shielding layer (5) tightly. The heat preservation water pipe is good in heat preservation effect, long in service life, simple in structure and suitable for wide popularization and application.

Description

technical field [0001] The invention relates to a thermal insulation water pipe, in particular to a thermal insulation water pipe made by sheet metal technology, which belongs to the technical field of thermal insulation water pipes. Background technique [0002] Water pipes are water supply pipes. Modern decoration water pipes are constructed by buried walls. There are three types of water pipes. The first type is metal pipes, such as hot-dip cast iron pipes with plastic lining, copper pipes, stainless steel pipes, etc.; The first category is plastic composite metal pipes, such as plastic composite steel pipes, aluminum-plastic composite pipes, etc.; the third category is plastic pipes, such as PB, PP-R, etc. Although the above-mentioned various water pipes have their own advantages, in order to ensure that the heat can be preserved in the hot water delivery process, a special heat-insulating water pipe is required. Especially in the northern cold region in winter, there a...
