Abstract

The invention relates to a sealing device for an electric switch of an explosion-proof thermostat. The sealing device comprises a plastic shell and a partition plate, wherein the partition plate is connected onto the plastic shell in a buckling way, and a sealing device is arranged at a joint of the partition plate and the plastic shell. The sealing device has the advantages that the joint of the partition plate and the plastic shell is sealed by the sealing device, so that the situation that electric sparks generated by turning on a contact inside the thermostat encounter flammable and explosive gas from refrigeration equipment to produce combustion or explosion is effectively avoided, and thus the explosion resistance of the product is effectively ensured, the user effect is improved, the use is safe and reliable, and the structure is simple.

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...
