Abstract
The invention provides a composite structure liquid conveying pipe. The composite structure liquid conveying pipe comprises a polymethyl methacrylate pipe, a felt layer, a metal net, a nylon layer and the like, wherein the polymethyl methacrylate pipe located on the inner layer makes direct contact with conveyed liquid, and as the properties of the polymethyl methacrylate pipe are stable, the polymethyl methacrylate pipe can be used for conveying various kinds of liquid. As polymethyl methacrylate has a high coefficient of thermal expansion, the polymethyl methacrylate pipe can handle the size changes of most kinds of liquid along with the temperature. In order to overcome the defect of low strength of the polymethyl methacrylate pipe, the metal net is arranged to play a role in binding the polymethyl methacrylate pipe, so that the mechanical strength is improved. In order to prevent the metal net from scratching the outer surface of the polymethyl methacrylate pipe, the stretchable felt is arranged between the metal net and the polymethyl methacrylate pipe. Finally, the outermost portion of the composite structure liquid conveying pipe is wrapped with nylon materials with stable performance, so that the whole composite structure liquid conveying pipe has both mechanical strength and thermal expansion properties.
Description
Technical field
The present invention relates to non-metal pipe technical field, be specifically related to a kind of composite structure Liquid transfer tubing.
Background technique
For carrying the important apparatus of gas and liquid in tubing engineering, when performing long distance delivery task, not only to consider the tolerance of tubing to environment itself, simultaneously because environmental change causes the change of liquid property also may cause burden to tubing.Too high the caused tubing fracture phenomena of thermal expansion coefficient such as owing to being transferred liquid just happens occasionally in the prior art.So how on the basis promoting tubing hot expansibility, ensure its intensity and environmental resistance, become technical problem urgently to be resolved hurrily.Although there is researcher to do many trials, do not find a kind of new material satisfied condition yet.
Summary of the invention
The present invention is intended to the technological deficiency for prior art, provides a kind of composite structure Liquid transfer tubing, is difficult to the tubing solving prior art the technical problem having good hot expansibility on the basis of proof strength concurrently.
For realizing above technical purpose, the present invention by the following technical solutions:
A kind of composite structure Liquid transfer tubing, comprise polymethylmethacrylate pipe, felt layers, wire netting, nylon layer, wherein felt layers is coated on polymethylmethacrylate pipe outside, is coated on felt layers outside, nylon layer is coated on wire netting outside, and described methyl methacrylate pipe, felt layers, wire netting, nylon layer fit tightly mutually.
As preferably, the material of described wire netting is steel.
As preferably, the thickness of described felt layers is 2 ~ 3mm.
As preferably, the external diameter of described tubing is 2 ~ 2.5 times of internal diameter.
In above technological scheme, the polymethylmethacrylate pipe being positioned at internal layer be transferred liquid and directly contact, because its character is comparatively stable, therefore can be used for carrying plurality of liquid.Because polymethylmethacrylate has higher thermal expansion coefficient, the Volume Changes of most liquid with problem therefore can be tackled.For making up the deficiency of polymethylmethacrylate pipe intensity, the present invention is provided with wire netting and plays bondage effect to polymethylmethacrylate pipe, thus improve its mechanical strength, for avoiding wire netting to the scuffing of polymethylmethacrylate tube outer surface, be provided with the felt equally with certain telescopicing performance between.Finally, the present invention, at the coated nylon material of stable performance of most external, also utilizes the characteristic that nylon material has higher thermal expansion coefficient simultaneously, makes tubing entirety have mechanical strength and hot expansibility concurrently.
