The Working Principle of Liquid Expansion Thermostat Temperature Sensing and Expansion: The liquid working fluid in the temperature sensing tube changes volume with temperature, pushing the membrane box connected to it to expand or contract. Mechanical Transmission: The membrane box drives the mechanical structure such as the spring sheet and spring sheet assembly through the cone head or push rod to trigger the contact to open and close. For example, when the temperature rises, the membrane box expands, pushing the contact to separate and cut off the power; after the temperature drops, it resets and turns on the power.
Structural Optimization:
In modern design, by adding spring sheets, ceramic rice supports (such as patent CN202323048939U) and capillary fixing technology (C-shaped bending hook), the risk of component falling off is reduced, the service life is extended and the stability is improved.
Performance parameters:
Typical technical indicators include temperature control range (-35℃ to +350℃), electrical load (16A/250V), response rate (≤1.0℃/min) and life (>100,000 times).
