Thermal insulation dual-channel PP-R pipe

Abstract

The invention discloses a thermal insulation dual-channel PP-R pipe which comprises an outer pipe with a long circular section and two inner pipes with the same specification and embedded in the outerpipe. A group of connecting ribs are arranged between the outer walls of the two inner pipes. Three groups of reinforcing ribs are arranged between the outer walls of the inner pipes and the inner wall of the outer pipe. Each group of reinforcing ribs are each of a multi-section type structure. The length of each reinforcing rib is 5 cm. A notch which is 1 cm long is formed between every two adjacent reinforcing ribs. The joint of each reinforcing rib and the corresponding inner pipe inwards shrinks and narrows to form a notch. The connecting ribs are each of a multi-section type structure. The length of each connecting rib is 5 cm. A notch which is 1 cm long is formed between every two adjacent connecting ribs. The single-pipe dual-channel water conveying is realized, the heat exchange between hot water and an external environment can be effectively prevented, and the heat loss in the water conveying process is reduced. Meanwhile, in the construction process, cold water pipes and hotwater pipes can be laid only with one-time pipe penetrating operation, and the construction cost is reduced.

Description

technical field [0001] The invention relates to a PP-R pipe, in particular a heat-insulating double-channel PP-R pipe. Background technique [0002] The water delivery pipeline of the solar water heater includes a cold water pipe and a hot water pipe. The two water pipes are erected outdoors. The temperature in autumn and winter is relatively cold. There is heat exchange with the surrounding air, and there will be heat loss, which will lead to a decrease in water temperature, which is more obvious for residents with lower floors. In addition, the conversion rate of the water heater in autumn and winter is low, so it is inconvenient for families with a large number of people to use. [0003] Therefore, measures need to be taken to reduce heat loss during hot water delivery. One way is to add an insulation layer outside the ordinary water pipes, which will significantly increase the construction difficulty and construction cost. In addition, in the building design, the passa...

Problems solved by technology

One way is to add an insulation layer outside the ordinary water pipes, which will significantly increase the construction difficulty and construction cost. In addition, in the building design, the passage for the solar water heater is very narrow, and there is no extra space to add an insulation layer. Therefore, Need to design a water pipe that can block heat loss
