Heat-preservation device for heat supply pipeline

Abstract

The invention discloses a thermal insulation device for heating pipelines, which comprises a thermal insulation main body, a controller, a resistance wire heating layer, a waterproof layer and a circuit breaker. The two ends of the thermal insulation main body are connected with installation rings. The inside is sequentially composed of a first heat preservation layer, a resistance wire heating layer, a second heat preservation layer and a waterproof layer, and the heat preservation body is arranged outside the pipe body, and a water leakage sensor and a temperature sensor are arranged between the pipe body and the waterproof layer. The output ends of the water leakage sensor and the temperature sensor are electrically connected to the input end of the D / A analog-to-digital converter, and the output end of the D / A analog-to-digital converter is electrically connected to the input end of the controller, and the output of the controller The terminal is electrically connected to the input terminal of the A / D digital-to-analog converter, and the output terminal of the A / D digital-to-analog converter is electrically connected to the input terminals of the frequency converter, the alarm and the short-circuit protector respectively. The invention can prevent equipment from being damaged due to water leakage of the pipeline while keeping the heating pipeline warm.

[0002] At present, thermal insulation is also called thermal insulation. Thermal insulation is a technological measure taken to reduce the transfer of heat from the system or the introduction of external heat into the system. Thermal insulation includes thermal insulation and cold insulation. The significance of pipe insulation is to reduce the loss of cold and heat and save energy. , improve the economy of system operation, heat insulation of pipelines and especially high-temperature pipelines can reduce the temperature of the outer surface, improve the surrounding working conditions, and prevent operators from being scalded or frostbite. Pipeline insulation is widely used in liquid and gas transportation pipe networks. In thermal insulation transportation pipelines, pipeline insulation, especially high-temperature pipeline insulation, is a very important link. The success of this link is directly related to whether the pipeline can be put into use normally. The insulation device on the market uses heating wire to insulate the pipeline. Heating, but once the pipeline leaks, it will cause a short circuit, cause harm, and poor safety
