Water-storing connection pipe

Abstract

The invention discloses a water-storing connection pipe, comprising: a first connection flange, a second connection flange and a pipe body; the first connection flange and the second connection flange are symmetrically arranged at two ends of the pipe body, the pipe body includes a pipe body inflow end, a pipe main part and a pipe body outflow end sequentially from left to right, the pipe main part is arranged between the first connection flange and the second connection flange, the pipe main part is a spherical part with openings in two ends, a water storage channel is arranged at the inner bottom of the pipe main part in a protruding manner, a heating pipe is arranged in the water storage channel, and pneumatic pipes inserted into the pipe main part are arranged at two ends of the inner top of the pipe main part respectively. The water-storing connection pipe has the advantages that a liquid is stored in the structure of the spherical pipe main part itself, heat is produced via the heating pipe, the liquid is then squeezed to two ends of the pipe main part via external pressure to form an inner circulation in the pipe body, and the risk of the pipe body being freeze-cracked due to internal freezing of the pipe is reduced.

Description

technical field [0001] The invention relates to pipe fittings, in particular to a water storage type connecting pipe. Background technique [0002] The connecting pipe plays the role of liquid distribution and pipeline connection in the pipeline. It can change the flow direction of the liquid, the length of the pipeline and the flow of the liquid. [0003] As we all know, when pipes, especially plastic pipes, are used in winter, they are most afraid of freezing inside the pipes, which will cause liquid blockage in the pipes or pipe cracking, resulting in heavy maintenance tasks and high maintenance frequency, which will increase operating costs. Contents of the invention [0004] The purpose of the present invention is to provide a water storage type connecting pipe, which forms the internal circulation of the pipe body and reduces the risk of the pipe body freezing and cracking caused by the internal freezing of the pipe. [0005] For reaching this purpose, the present i...
