Problems solved by technology

However, when the temperature is lower than minus 5°C, the thermal insulation effect of the thermal insulation material is not good, and the phenomenon of freezing and blockage will still occur; when steam is heated to prevent freezing, the phenomenon of "running, popping, dripping, and leaking" often occurs in steam tracing pipes, and its heat Low utilization rate, waste of energy

Embodiment Construction

[0020] The following examples are provided to specifically describe the present invention. It is necessary to point out that the following examples are only used to further illustrate the present invention, and can not be interpreted as limiting the protection scope of the present invention. Those skilled in the art according to the present invention SUMMARY OF THE INVENTION Some non-essential improvements and adjustments made to the present invention still belong to the protection scope of the present invention.

[0021] Such as figure 1 As shown, an electric heat tracing system for pipeline antifreeze includes two heating cables 4, and the two heating cables 4 are arranged on two opposite sides of a vertical pipeline 3-2, or on two opposite sides of a horizontal pipeline 3-1. The lower side is at an angle of 120°, and is fixed to the pipeline with a fixing belt 7; a temperature sensor 6 is provided on the side of the pipeline away from the heating cable, and the temperature ...

Abstract

The invention discloses an electric tracing system for preventing the freezing of pipelines, which comprises heating cables, and the heating cables are arranged on the outside of a pipeline and fixed with the pipeline by fixing straps; a temperature sensor is arranged on one side of the pipeline, which is far from the heating cables, both the temperature sensor and the heating cables are electrically connected with a temperature controller, and the temperature controller is connected with a power supply. When the temperature sensor detects that the temperature of the pipeline is lower than set temperature, the temperature controller is connected with the power supply, and the heating cables start to operate; when the temperature sensor detects that the temperature of the pipeline is higher than the set temperature, the temperature controller is disconnected from the power supply, and therefore the heating cables can operate under the most economical and reasonable state and meet the requirement on medium temperature.

Description

technical field [0001] The invention relates to an electric heating system for pipeline antifreeze. technical background [0002] There are various gas pipes, water pipes, waste water pipes and other pipes buried underground in the city, which are related to the daily life of thousands of households. But in winter in the northern region, the temperature is low, the pipeline is easy to freeze and crack, or the pipeline is blocked, such as the water in the water pipe freezes and blocks the water pipe; after the natural gas in the natural gas pipeline is throttled by the pressure regulating valve, the gas expands, absorbs a large amount of heat, and the temperature is low It will cause natural gas to generate hydrates, block the pipeline, affect people's normal life, and bring safety hazards. In addition, the antifreeze of pipelines in the north has always been a major problem for civil construction technicians. Therefore, the pipeline should adopt pipeline heat tracing meas...
