Abstract

The invention relates to an electric switch sealing device of an anti-explosion temperature controller. The electric switch sealing device comprises a plastic shell and a partition plate, wherein the partition plate is fastened on the plastic shell; and a sealing device is arranged at a joint of the plastic shell and the partition plate. The electric switch sealing device has the advantages that the joint of the plastic shell and the partition plate is sealed through the sealing device, the phenomenon that spark generated when contacts in the temperature controller contact with each other meets flammable and explosive gas of refrigerating equipment and combustion or explosion is caused is prevented effectively, so that explosion resistance of the electric switch sealing device is guaranteed effectively, a service effect is improved, and the electric switch sealing device is safe and reliable, and is simple in structure.

Description

technical field [0001] The invention relates to an electrical switch sealing device of an explosion-proof thermostat. Background technique [0002] The thermostat is a switch that integrates programmers and software and realizes intelligent temperature control. It can freely adjust the indoor temperature. The existing refrigeration medium is fluorine-free gas. Although it is environmentally friendly, it is a flammable and explosive gas. When using this When a new working fluid is introduced, if there is leakage in the refrigeration system, when the gas concentration in the refrigeration equipment reaches a certain value, it will explode due to a slight electric spark, and the contacts inside the existing thermostat, when they are turned on or At the moment of disconnection, electric sparks will be generated, which is prone to explosion and poses a hidden danger to the safety of refrigeration equipment. Compared with the electrical switch of an explosion-proof thermostat desc...
