Problems solved by technology

[0002] The thermostat is a switch that integrates a programmer and software and realizes intelligent temperature control. It is used to sense the temperature of the pipeline or tank wall and is used to control a single heat tracing circuit, or as a signal control of a contactor switch for multiple heat tracing circuits. Existing Most of the current thermostats have the disadvantages of poor use effect, cumbersome structure, and poor sealing effect, which need to be improved

Abstract

The invention belongs to the technical field of mechanical temperature controllers, and particularly relates to an anti-explosion temperature controller used for controlling a dangerous area heat tracing system. Sealing members are arranged at the connecting positions so that the sealing performance of the anti-explosion temperature controller can be effectively guaranteed. When set flammable and explosive gas or steam explodes in a shell, a base is not damaged and the explosive material is not spread so that the anti-explosion temperature controller has great anti-explosion performance. Temperature is monitored in real time through an induction bulb probe. When temperature rises, silicone oil in the induction bulb probe thermally deforms and expands and silicone oil in a stainless steel pipe also thermally expands so as to push a push rod to be close to a stroke switch and the circuit is connected. When temperature drops, silicone oil in the induction bulb probe coldly deforms and contracts to drive the push rod to be away from the stroke switch, and the circuit is disconnected and the objective of constant temperature is achieved. The method is stable and reliable, low in on-off temperature difference, high in temperature control adjustment range, high in overload current, high in adjustment precision, sensitive in switching motion and long in the service life.

Description

technical field [0001] The invention belongs to the technical field of mechanical thermostats, and in particular relates to an explosion-proof thermostat for controlling heat tracing systems in hazardous areas. Background technique [0002] The thermostat is a switch that integrates a programmer and software and realizes intelligent temperature control. It is used to sense the temperature of the pipeline or tank wall and is used to control a single heat tracing circuit, or as a signal control of a contactor switch for multiple heat tracing circuits. Existing Most of the current thermostats have the disadvantages of poor use effect, cumbersome structure, and poor sealing effect, which need to be improved. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the invention provides an explosion-proof thermostat with good sealing effect and simple structure. [0004] The present invention is achieved through the following technical solutions: [00...
