Description

Antifreezing tube

Technical Field

The utility model relates to a hose with an antifreezing function, and belongs to the technical field of pipelines.

Background

Hoses are an important component in the modern industry. The hose is mainly divided into: threading hose, drainage hose, ventilation hose, gondola water faucet hose, pencil pipe, conveying hose, the hose mainly divide into according to the material: stainless steel hose, metal hose, corrugated hose, rubber hose, plastic hose, etc.

When the hose is used as a drainage application, the hose is mainly used for realizing drainage tasks such as sewage, rainwater and the like, and when the hose is used as a conveying application, the hose is mainly used for conveying flowable liquid.

At present, hoses for drainage and transportation use need to be operated in a low-temperature environment, and therefore cold resistance of pipes needs to be considered. In areas with high latitude such as northeast and Russian in China, the temperature is low in winter, usually reaches tens of degrees below zero, the hose becomes brittle in a low-temperature environment, the elasticity of the hose is reduced, the situation of burst easily occurs, and in addition, the flowable liquid in the hose is even frozen, so that the hose is blocked.

In order to solve the technical problems, the prior art also makes different improvements on the basis of the hose, for example, an insulating layer is coated or wrapped on the outer wall of the hose so as to solve the problems of hose cracking and liquid freezing in the hose; or the heating wire is embedded in the hose, the temperature of the hose is increased in a heating mode by the heating wire, and the problem of liquid freezing in the hose is solved. However, these approaches have different drawbacks, mainly expressed in:

1. when the outer wall is coated or wrapped with the heat preservation layer, the operation is complex, and the heat preservation effect of the hose can be ensured only by standardized operation of an operator; this approach is therefore time consuming and laborious;

2. when the heating wire is embedded in the hose, the plastic material of the hose is easy to burn in the heating process due to the lower toughness degree of the hose, so that the hose is damaged, and even the heating wire exposes out of the outer surface of the hose, so that the electric leakage phenomenon is generated in the hose in use.

Based on the above-mentioned problem, it is urgent to propose an antifreezing hose, under the prerequisite of guaranteeing hose life, realize the heating to avoid the problem that the inside liquid of hose freezes under the low temperature environment.
