Environment-friendly PVC pipe

Abstract

The invention belongs to the technical field of PVC pipes, and particularly relates to an environment-friendly PVC pipe. The environment-friendly PVC pipe comprises a pipe body, clamping films are arranged on the two sides of the pipe body at intervals in the vertical direction, two flow guide grooves are formed in the inner wall of the pipe body, the height of the middles of the flow guide grooves is larger than that of the two ends, and two flow guide pipes are arranged in the single flow guide groove. Through the clamping films and the flow guide pipes, during freezing, the clamping films become convex, freezing and cracking caused by expanding of the pipe body can be prevented, meanwhile, the clamping films which become convex can be matched with a fixing clamping ring which is mountedon the wall and used for fixing the pipe body, the clamping films are clamped on the fixing clamping ring, all weight of the frozen pipe body is dispersed on the fixed clamping ring through the clamping films, the dangerousness of the tensile failure of the pipe body is reduced, meanwhile, during defrosting, through the flow guide pipes, defrosted water flows back to ice blocks on the clamping films, melting of the ice blocks on the clamping films can be quickened, and the influence that during defrosting, due to the fact that the clamping films become convex, ice columns cannot fall off is avoided.

Description

technical field [0001] The invention belongs to the technical field of PVC pipes, in particular to an environment-friendly PVC pipe material. Background technique [0002] PVC can be divided into soft PVC and hard PVC. Among them, hard PVC accounts for about 2 / 3 of the market, and soft PVC accounts for 1 / 3. Soft PVC is generally used for floors, ceilings and leather surfaces, but because soft PVC contains plasticizers and has poor physical properties, its scope of use is limited. Rigid PVC does not contain plasticizers, so it is easy to form and has good physical properties, so it has great development and application value. In the production process of PVC materials, several additives are bound to be added, such as stabilizers, plasticizers, etc. If all environmental additives are used, then PVC pipes are also non-toxic, tasteless and environmentally friendly products. [0003] On the outer walls of some high-altitude buildings, some soft PVC pipes are clamped on the wal...
