An easy-limit floor heating composite pipe assembly with a filter joint

Abstract

The invention discloses an easy-to-limit floor heating composite pipe assembly with a filtering joint in the technical field of floor heating pipes. The easy-to-limit floor heating composite pipe assembly with the filtering joint is provided with a floor heating composite pipe, outer skin, a jacket, an inner pipe and a nail clamping sleeve; the outer skin adheres to the outer wall of the circumference of the floor heating composite pipe; the inner wall of the circumference of the floor heating composite pipe adheres to the outer wall of the circumference of the jacket; and the outer wall of the circumference of the inner pipe and the inner wall of the circumference of the jacket are in sleeved connection. According to the easy-to-limit floor heating composite pipe assembly with the filtering joint, in the using process of the floor heating composite pipe, through a top cover with a filter screen layer, filtering substances are stored and replaced, in cooperation with an inner tank containing slow release balls, a purifying and corrosion preventing and scale inhibiting effect can be achieved, water scale piling in the floor heating composite pipe is avoided, and the flow speed of inner low temperature hot water is made stable; and a main plate and an auxiliary plate with clamping columns are additionally arranged, after the nail clamping sleeve penetrates through a main plate hole through a ground nail, a limiting plate is made to be in contact with the clamping columns, the stable effect of the floor heating composite pipe is improved, and the floor heating composite pipe cannot waggle in the nail clamping sleeve.

Description

technical field [0001] The invention relates to the technical field of floor heating pipes, in particular to an easily-limited floor heating composite pipe assembly with a filter joint. Background technique [0002] Floor heating pipe refers to a kind of pipe used as a low-temperature hot water circulation carrier in the low-temperature hot water ground radiation heating system (referred to as floor heating). According to national and international product standards, raw materials for producing plastic pipes and plastic pipe fittings for hot and cold water , it must be a special material for pipelines that has passed the qualification judgment after being tested in accordance with the provisions of GB / T18252-2000 "Determination of Long-term Hydrostatic Strength of Thermoplastic Pipes by Extrapolation Method for Plastic Pipeline Systems". That is to say, each raw material manufacturer must make a creep failure curve that meets the predicted strength reference curve according ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide an easy-limit floor heating composite pipe assembly with a filter joint to solve the problem of lack of filtering and processing of internal low-temperature hot water during the use of the existing floor heating composite pipe proposed in the background art. During the long-term use of the floor heating composite pipe, there will be scale accumulation in the inner pipe, which will affect the flow rate, reduce the heat preservation effect, increase energy consumption, and affect the service life. The layout is carried out on the thermal insulation board with composite surface layer, but when the staple sleeve and the floor heating composite pipe are in contact, there will be a gap at the bottom of the staple sleeve. Although the position of the floor heating composite pipe can be fixed, the floor heating composite pipe will be stuck. Internal rolling of nail sleeves, issues affecting layout and stability
