PE (poly ethylene) corrugated compensator for high-temperature water

Abstract

The invention discloses a compensator used in a concentrated-heating hot water network, and concretely relates to a PE (poly ethylene) corrugated compensator for high-temperature water. The compensator comprises an operating tube compensator and an outer polyethylene sleeve, wherein the operating tube compensator is externally sleeved with a hard thermal insulation layer and a soft thermal insulation layer, the outer polyethylene sleeve is tightly wrapped on the outsides of the hard thermal insulation layer and the soft thermal insulation layer, and the hard thermal insulation layer is tightly wrapped on one end of the operating tube compensator and raised parts; the soft thermal insulation layer is tightly wrapped on the other end of the operating tube compensator; and the outer edge of the soft thermal insulation layer is provided with a corrugated pipe. The compensator disclosed by the invention is extremely compact in structure; the compensator is strong in bearing capacity, has the characteristics of acid, alkali and chloride ion corrosion resistance, and prevents the rupturing of an outer pipe in the process that an operating tube is drawn, thereby prolonging the service life of the compensator and saving energy; meanwhile, because of the setting of a protective cover, the heat preservation effect can be further increased; due to the selection of materials, the compensator is more practical; and because of the simple structure and process, the installation process is easier, thereby solving the problem of inconvenience in installation.

Description

technical field [0001] The invention relates to a compensator used in central heating and hot water networks, in particular to a high-temperature water PE corrugated compensator. Background technique [0002] In the existing central heating hot water network technology, thermal insulation compensators are often used for compensation. The existing thermal insulation compensators have a hard insulation layer and a soft insulation layer outside the working tube compensator, and polyethylene is used outside the insulation layer. Outer casing, during the operation of the pipe network, when the working pipe compensator stretches, it will cause the welded part of the outer casing polyethylene pipe to break. After the water enters, the insulation layer will fail, and the steel pipe will be corroded, which will greatly shorten the service life of the working steel pipe, and in severe cases, the pipe network will be scrapped. [0003] At the same time, a corrugated compensator disclo...

Problems solved by technology

But it also has disadvantages that are not easy to solve: for example, the axial corrugated compensator generates pressure thrust on the fixed bracket, resulting in a large thrust of the fixed bracket, resulting in high cost; in addition, the corrugated compensator has a thin wall that cannot withstand torsion, vibration, and poor safety; equipment A series of shortcomings such as high investment, strict design requirements, high construction and installation precision, and often not reaching the expected life

Problems occurred in the design, most of which belonged to ignorance of the design characteristics of corrugated compensator pipelines, resulting in calculation errors and unreasonable selection of compensation piping systems
