Problems solved by technology
[0003] Due to its convenience, boilers are widely used in life and business. In the use of boilers, sometimes it is necessary to detect the temperature of a certain node in a part of the pipeline or the temperature of the entire pipeline. However, due to the relatively narrow boiler pipeline, it will It is not realistic to place the temperature detection device directly inside the boiler pipe

The invention discloses a detection device for detecting the water temperature in a boiler pipeline. The detection device for detecting the water temperature in the boiler pipeline comprises a boilerpipeline, a sealed shell, a temperature sensor and a backwater chamber, wherein the boiler pipeline, the sealed shell, the temperature sensor and the backwater chamber are formed in a boiler. According to the detection device for detecting the water temperature in the boiler pipeline, a sampling detection principle is adopted, and the temperature sensor is arranged at a certain joint of the boilerpipeline to detect the water temperature in the boiler pipeline, specifically, a condensing annular pipe is arranged at the periphery of the backwater chamber through the principle that air contractswhen encountering cold, when sampling detection is required, cold water is introduced into the condensing annular pipe, so that the air in the backwater chamber is contracted, and then the air in a water outlet annular pipe is contracted; a pipeline in the detection device is filled with the water in the boiler pipeline under the action of air pressure, and the temperature of the water is detected by the temperature sensor; and after the detection is finished, the air above the pipeline is compressed by an electric injector, so that the water in the whole pipeline is discharged, and then thewater temperature is detected for the next time, so that the cycle is repeated.
Description
technical field [0001] The invention relates to a water temperature detection device, in particular to a detection device for detecting the water temperature in a boiler pipe. Background technique [0002] A temperature sensor is a sensor that senses temperature and converts it into a usable output signal. The temperature sensor is the core part of the temperature measuring instrument, and there are many varieties. According to the measurement method, it can be divided into two categories: contact type and non-contact type. According to the characteristics of sensor materials and electronic components, it can be divided into two types: thermal resistance and thermocouple. The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. The original meaning of the pot refers to the wat...
