Thermal actuator temperature control element technical parameters
Temperature regulating thermal element is a kind of heat energy into mechanical energy, can be quickly after it has induction temperature changes automatically spread the function of mechanical motion, it is the mechanical action of the application of thermal expansion material, its mechanical movement is not affected by the surrounding environment, are key components in all kinds of temperature control, control system, temperature adjusting range is extensive, control temperature accurately, the advantages of simple structure, reliable performance. Has been widely used in automobile industry, building heating, sanitation clean bath, hvac, industrial automatic control, fire extinguishing, household appliances, solar water heater, oil chemical industry, shipbuilding, safety devices, aerospace and other fields.Also known as electrothermal constant temperature controller, electric actuator is a new concept for remote control system flow, heat (cold) device, applicable to the heating of residential, shopping mall, hotel and the temperature control of the central air conditioning, room temperature control.The electrothermal actuator is mainly used in the heating system, the control of the shutdown and the opening. It is applied to the electric drive part of the electric heat actuator of the branch valve, small valve and dynamic balance valve. The work is running noiseless and the nut connection is installed in a simple, quick installation and easy to remove.Working principle:The electric heat actuator is composed of temperature controller, valve actuator and valve. Thermostat installed on the room interior walls, with the cable connected to the electric actuator, generally use 100 cm long cable connects actuators to the selected control points (thermostat, programmer, timer or other remote devices). The implement nut is connected to the valve. When indoor temperature reaches the temperature of the temperature controller is set, electric actuators are thermistor begins to work, the heating thermal expansion device to close the valve, on the other hand, the indoor temperature is reduced, the thermostat disconnect, actuators, expansion system contraction, open the valve.修改翻译结果
