Precise adjustable liquid expansion temperature controller

Abstract

The invention discloses a precise adjustable liquid expansion temperature controller, and the controller comprises a switch assembly and a liquid closed power system arranged on the switch assembly and used for generating switch driving quantity matched with a switch. According to the precise adjustable liquid expansion temperature controller, through the liquid intangibility and uniform moleculardistribution, the temperature is sensitive to temperature changes, the volume expansion coefficient is high, and an elastic energy conversion diaphragm capsule is combined, so the tiny change of thetemperature can be converted into a corresponding displacement and force; a temperature control probe is directly contacted with an equipment working environment, and no indirect energy transmission component is arranged in the middle; the temperature is converted into a temperature variable (heat energy) by the diaphragm capsule and is directly applied to the switch contact assembly; by means ofthe structure, tiny temperature changes of the control environment can be converted through the diaphragm capsule and transmitted to the switch assembly, so the problem of energy inconsistency causedby energy transmission loss in the liquid expansion temperature control process and part deviation is solved, the one-to-one relation of energy transmission is achieved, precise temperature control over equipment is achieved, and better use prospects are brought.

Description

technical field [0001] The invention relates to the field of temperature controllers, in particular to a precision adjustable liquid expansion temperature controller. Background technique [0002] The installation and temperature control methods of products and equipment in the prior art are in the form of direct sensing and compensation temperature sensing. The direct sensing mode is in direct contact with the heat source. The switch is placed in the test environment and exposed to the control environment, which is affected by various pollution and safety; compensation The temperature control method is indirect temperature control, which solves the installation pollution and safety problems, but due to the installation environment and the size of the equipment, the environment changes slightly, resulting in large deviations, which is not conducive to accurate and long-distance temperature control; [0003] The liquid expansion direct temperature sensing indirect conversion ...

Problems solved by technology

Because the temperature change (heat energy) is converted into the action value that the switch can recognize through the bellows, the isomorphic elastic action plate is transmitted to the contact piece assembly, thereby pushing the switch action and realizing the switch operation, but there is a coordination deviation in the transmission of the intermediate process. The temperature (heat energy) converted by the bellows cannot be completely transferred to the switch assembly, and there will be a small hysteresis and deviation. Although it can meet the use of most situations, it still cannot satisfy people's needs for some environments that require higher temperature control. Use requirements, for this reason, we propose a precision adjustable liquid expansion thermostat
