Abstract
The invention is a high-pressure detachable temperature sensor device, which includes a temperature sensor, temperature sensor wiring, a protective casing, a sealing casing, a tube plate, a flange plate, an external thread sealing joint, a compression nut, and a first sealing sleeve 1. The second sealing sleeve, the sealing sleeve is sleeved on the outer circle of the rear end of the temperature sensor, and the two end faces of the sealing sleeve are respectively welded to the outer circle of the temperature sensor. One end face of the protective sleeve is welded to the external thread sealing joint, part of the outer circle of the protective sleeve is welded to the flange plate, and the other end face of the protective sleeve is welded to the tube plate. The temperature sensor, together with the sealing sleeve, extends into the external threaded sealing joint and the inside of the protective sleeve. Loosen the compression nut, and the damaged temperature sensor can be taken out from the protective sleeve, external thread sealing joint, first sealing sleeve, second sealing sleeve, and compression nut, which can save 90% of the replacement cost, and the sealing Works well and is easy to replace.
Description
technical field [0001] The invention relates to a high-voltage detachable temperature sensor device for an explosion-proof electric heater. Background technique [0002] In order to increase the temperature of oil, water and gas, explosion-proof electric heaters are commonly used. The core component of the explosion-proof electric heater is the explosion-proof electric heating tube. In order to prevent the surface temperature of the explosion-proof electric heating tube from being too high and cause an explosion, two temperature sensors must be used to measure the surface temperature of the explosion-proof electric heating tube at any time, and the temperature is controlled within a certain range through the automatic control cabinet. Take the average value of two temperature sensors. The temperature sensor should be inserted into the barrel of the explosion-proof electric heater. The front end of the temperature sensor is the temperature sensing area, and the front end is...
