PP-R pipe fitting for drainage

Abstract

The invention discloses a PP-R pipe fitting for drainage, and belongs to the technical field of PP-R pipe fittings. According to the PP-R pipe fitting, the freezing tolerance of a pipe body can be improved by utilizing the heat insulating ability of a plurality of heat preservation cotton when the temperature is lower; an acetic acid solution freezes in advance by utilizing the characteristic that the freezing point of the acetic acid solution is higher than that of water when the temperature in the pipe is close to the freezing point of water; under the action of continuous contraction of a cold contraction hemisphere, a crisp shell is poked by a conical soft film, and then a heating material is dispersed and falls under the pushing of a compression balloon, so that the heating material is oxidized after encountering oxygen to generate a large amount of heat, a certain heat preservation effect on the pipe body is achieved, and the freezing speed of the water in the pipe is delayed; and a plurality of connecting rulers and a sound making hammer are arranged in a matched mode, so that when the temperature in the pipe is close to the freezing point of the water, the sound making hammer makes a sound to achieve the reminding purpose, maintenance personnel can treat a water pipe in time, and the situation that the water in the pipe gradually freezes along with time, and consequently the pipe is broken is avoided.

Description

technical field [0001] The invention relates to the technical field of PP-R pipe fittings, and more specifically relates to a PP-R pipe fitting for drainage. Background technique [0002] PP-R material is three-type polypropylene resin, which is made of random copolymerized polypropylene as the base material through advanced gas phase copolymerization process, that is, random and uniform polymerization of PE in the molecular chain of PP. PP-R material is one of the pipe materials with the best comprehensive performance at present. [0003] Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipes, pipe fittings made of PP-R materials have energy-saving and material-saving features, environmental protection, light weight and high strength, corrosion resistance, smooth inner wall without scaling, and easy construction and maintenance. , long service life and other advantages, widely used in building water supply and drainage, urban and ru...

Problems solved by technology

[0004] However, the existing PP-R pipe fittings have poor antifreeze ability. When the ambient temperature is low, once the flow of liquid in the pipe is stopped, the liquid will gradually freeze into ice. During the ice process, the volume gradually increases, causing the tube body to rupture
