Abstract

The invention discloses a heat-resistant and explosion-proof temperature-measuring thermocouple structure, which includes a shell assembly, connecting wires, thermocouple wires and a fixative, a support assembly including a support rod, a top post and a first spring, and a plurality of top posts and support rods Fixed connection, the shell assembly includes a slide bar, lock piece and protective cover, the slide bar and the support bar are slidingly connected, a plurality of lock pieces are rotationally connected with the slide bar, and are close to the top column, and a first Spring, when the slide bar is impacted by high pressure, the first spring contracts to absorb the impact, and the top column contacts the lock piece to make the lock piece open and contact the wall of the container to be tested to prevent the slide bar from continuing to move outward. The protective cover and the slide bar are fixedly connected. The coupler wire is located in the protective sleeve, and the connecting wire passes through the support rod, the sliding rod and the protective sleeve, and is electrically connected with the thermocouple wire. The high temperature resistant fixative is filled in the protective sleeve, so that the thermocouple can be used in a high temperature and high pressure environment. normal work.

Description

Technical field [0001] The present invention relates to the field of thermocouples, and more particularly to a heat-resistant explosion-resistant thermocouple structure. Background technique [0002] The thermocouple is a temperature measuring element commonly used in the temperature measuring instrument, which is directly measured and converts the temperature signal into a thermometrophic signal, converted to the temperature of the medium by the electrical instrument (secondary instrument). [0003] In the field of chemical industry, with the development of science and technology, the control of the manufacturing process is increasing, and the parameters such as temperature during the manufacturing process are needed, but the chemical production process is often accompanied by various flammable. The explosive chemical gas, the generated high temperature environment and the severe impact are easy to damage the thermocouple, so the ordinary thermocouple does not meet the demand, a...
