Description

Technical Field

[0001] The utility model relates to the technical field of temperature monitoring of thermal pipelines, in particular to a temperature monitoring device for thermal pipelines. Background Art

[0002] Thermal pipes, also known as thermal networks, are a type of pressure pipes that transport the heat energy produced by boilers to indoor heating equipment through heat media such as steam and hot water to meet the needs of production and life. Starting from the boiler room, direct-fired machine room, heating center, etc., a thermal network is formed by multiple heating pipes from the heat source to the thermal entrance of the building.

[0003] The internal temperature of a thermal pipeline needs to be measured when it is in use. Usually, an external pipeline is opened at the upper end of the pipeline and a temperature measuring device is threadedly connected for measurement. Sometimes, a shunt pipeline needs to be installed first and then a temperature measuring device needs to be installed on the upper end of the shunt pipeline. The pressure of the thermal pipeline is relatively large, and long-term shunt may cause pressure instability and accidents. At the same time, since hot water is always flowing in the pipeline, the measurement result may have a large deviation. At the same time, when the temperature measuring device is damaged, the thermal pipeline needs to be closed first, which is inconvenient. For this reason, we propose a temperature monitoring device for the thermal pipeline. Utility Model Content
