Description

Single-pipe circulating water floor heating laying water pipe

Technical Field

The invention relates to the technical field of heating devices, in particular to a single-pipe circulating laying water pipe for water floor heating.

Background

In chilly winter, in order to improve the travelling comfort of living in residence, people can install heating installation at home, and along with the development of science and technology, more and more novel heating mode appears in people's the field of vision, and warm up with water is exactly one of them, warm up with water is the hot water that the temperature is not higher than 60 ℃ as the heat medium, the heating tube internal circulation that is buried in the below ground filling layer flows, heat whole floor, through ground with the heat transfer mode of radiation and convection current to the heating mode of indoor heat supply.

In the floor heating industry, the fact that the floor heating installation has the theory of 'three-part products and seven-part installation' means that the quality of the floor heating installation directly affects the heating effect and the service life of the floor heating, in the floor heating, the installation is mainly the laying of the heating water pipes, in order to ensure that the heating water pipes are uniformly distributed on the ground, the water pipes need to be turned to bend in the laying process, in the traditional water pipes, hot water flows in the water pipes only once, in order to achieve the good heating effect, the laying density of the water pipes needs to be increased to increase the bending angle of the water pipes, the phenomena of deformation and dead bending of the water pipes easily occur, the hot water circulation is not smooth, in the flowing process of the hot water, the temperature of the water pipes close to a water inlet is gradually reduced and is higher than that of the water pipes close to a water outlet, so that the temperature difference exists in an indoor place due to unevenness, the indoor comfort is reduced, the circulating line of the traditional heating pipe is complex, and errors are easy to occur in design and installation.

In order to solve the problems, the inventor provides the laying water pipe for the water-floor heating with the single-pipe circulation, so that the heating effect of the water pipe is improved, the laying density of the water pipe is reduced, the laying difficulty is reduced, meanwhile, the high-density and high-amplitude bending of the water pipe is avoided, the hot water circulation is smoother, the phenomenon of regional temperature difference caused by uneven indoor heating is avoided, and the heating comfort is improved.
