antifreeze pipeline

Abstract

The invention discloses an antifreeze pipeline, which comprises a pipeline body, a filter screen is fixed on the inner wall of the pipeline body, a piston tube is fixed inside the pipeline body, a piston slides inside the piston tube, and the piston is close to the filter screen A telescopic spring is fixed between one side of the piston tube and the inner wall of the piston tube, and a connecting rod is fixed on the side wall of the piston close to the filter screen, and the connecting rod extends through the inner wall of the piston tube to the outside and is fixedly connected with a Arc-shaped plate, the side of the piston close to the filter screen is also fixed with a fixed rod, the outer wall of the pipeline body is inserted with an insertion rod whose end extends into the piston tube and is located at the end of the fixed rod, and the fixed rod Electric contacts are fixed on the ends of the rod and the insertion rod. In the present invention, when the liquid circulation in the pipeline is not smooth, impurities are scraped off through the heating of the heating tube and the movement of the wedge plate, which avoids the problem of liquid freezing or poor circulation caused by impurities, and ensures that the liquid can be transported normally.

Description

technical field [0001] The invention relates to the technical field of pipelines, in particular to an antifreeze pipeline. Background technique [0002] A pipeline is a device used to transport gas, liquid or fluid with solid particles connected by pipes, pipe connectors and valves. Pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. [0003] In order to avoid the internal freezing of the existing pipelines during liquid transportation or drainage work, the outer wall of the pipeline is wrapped with cold-proof cloth to prevent the cold. When the liquid still freezes in the pipeline, it causes the problem that the liquid cannot be transported due to the freezing. Contents of the invention [0004] The purpose of the present invention is to solve the problems in the background technology, and propose a kind of anti...
