Novel hair-imitating anti-freezing pipeline suitable for low-temperature environment

Abstract

The invention discloses a novel hair-imitating anti-freezing pipeline suitable for a low-temperature environment, and belongs to the field of pipeline equipment. The pipeline is characterized in thatmultiple heat release pores accommodating heat release balloons can be preset on the outer surface of the pipeline by imitating hairs on an animal body; meanwhile, a suspended cold contracting movingball is innovatively arranged, and the cold contracting moving ball actively moves under the action of magnetic attraction by means of the characteristic of contracting during cold; and water squeezedout during contraction is frozen along a double-state hair needle to form an ice needle, so that the heat release balloons are punctured to trigger an oxidation reaction to release a large amount ofheat. According to the pipeline, the released heat is used for heating and protecting the pipeline, so that the damage of external low temperature to the pipeline is prevented; after the temperature rises, the cold contracting moving ball can rise again to return to an original position and repeat the action so that the external temperature can be automatically sensed, and then the pipeline heating action can be triggered; and the pipeline is effectively subjected to heat preservation by imitating the animal hairs, so that the anti-freezing performance of the pipeline to the external low temperature is remarkably improved.

Description

technical field [0001] The invention relates to the field of pipeline equipment, in particular to a novel hair-like antifreeze pipeline suitable for low-temperature environments. Background technique [0002] The current ordinary PPR cold and hot water pipes have serious low-temperature brittleness at around 0°C, and are easy to break when the temperature is below zero. Therefore, plastic pipes must be able to ensure proper strength and toughness in severe cold environments. [0003] Plastic pipes for antifreeze in home decoration are required to be easy to install, safe, environmentally friendly, non-polluting, and beautiful in appearance. The Chinese patent application number is CN201610978761.3, which proposes an antifreeze double-layer composite pipe, which consists of two parts: a dense inner layer and an outer layer. The dense inner layer thickness ratio is 15-85%, the outer layer thickness ratio is 85-15%, the dense inner layer matrix is ​​high-density polyethylene, t...

Problems solved by technology

[0007] The elastic body installed in the pipeline antifreeze device in the above scheme is prone to aging and loss of elasticity in the extremely cold environment for a long time, thus losing the effect of preventing the pipeline from bursting when the liquid freezes

[0008] Therefore, in the prior art, there is no real means of effectively anti-freezing pipelines, and there are many deficiencies in conventional methods, which seriously restrict the applicability of plastic pipelines in low temperature environments.
