A casting tee pipe

Abstract

The invention belongs to the technical field of three-way pipes and particularly relates to a casting three-way pipe. The casting three-way pipe comprises an inner pipe body and an outer pipe body, wherein the outer wall of the inner pipe body is coated with the outer pipe body; the outer pipe body is made of a rubber abrasion-resistant material; a heat preservation heating chamber is formed between the outer pipe body and the inner pipe body; the upper wall of the heat preservation heating chamber is laminated with a heat preservation fiber layer; a heating device is arranged in the heat preservation heating chamber and comprises an electric heating wire, a spiral heating tube and a spiral heat conduction tube; the electric heating wire is inserted into the spiral heating tube through aninsertion manner; the inside of the spiral heating tube is filled with heating liquid; the outer wall of the spiral heating tube is coated with the spiral heat conduction tube; a filling chamber is formed between the spiral heat conduction tube and the spiral heating tube; and the inside of the filling chamber is filled with drift sand; and the heating device is sleeved on the outer wall of the inner pipe body and is used for heating in the heat preservation heating chamber and conveniently thawing the frozen liquid in the inner pipe body.

Description

technical field [0001] The invention belongs to the technical field of three-way pipe fittings, in particular to a casting three-way pipe. Background technique [0002] Whether it is in the case of urban civil tap water supply or industrial water supply, the tee pipe is indispensable as a connecting part of the pipeline, and it is necessary to install the respective control valves on the main pipe and the branch pipe during installation and use. In order to provide protection for the maintenance of pipelines in different regions and the water supply of each branch in stages. Not only that, tee pipes and valves are often used in the pipeline transportation of oil and liquid chemical materials. [0003] When the existing tee pipe is in use, especially in cold winter, when the liquid in the pipe does not flow, the external low temperature environment will cause the liquid in the pipe to freeze, and the liquid will cause the tee to freeze. The pipe fittings are blocked, which ...

Problems solved by technology

[0004] In order to make up for the deficiencies in the prior art, the present invention proposes a casting tee pipe. The present invention is mainly used to solve the problem of the external low temperature environment when the existing tee pipe fittings are used in cold winter when the liquid in the pipe does not flow. It will cause the liquid in the pipe to freeze, and the liquid will block the tee fitting after freezing
