Principle and function of temperature control valve of screw air compressor

Each component of the screw air compressor has its unique and important role, such as air filter, oil filter, safety valve, temperature control valve, one-way valve, etc. If one of them is missing, the screw air compressor will not function properly. To run. The following is an introduction to the working principle and function of the temperature control valve:

　　The temperature control valve is composed of a valve body, a valve core, a temperature sensing element, a spring, etc., and its function is mainly to adjust the injection temperature. When the oil temperature measured by the temperature sensing element of the temperature control valve is lower than the operating value (the operating value of the temperature sensing element is generally 71 degrees), the lubricating oil returns directly from the oil and gas barrel to the host; when the temperature measured by the temperature sensing element of the temperature control valve When the oil temperature is higher than the action value, the thimble of the temperature sensing element of the temperature control valve moves, pushing the valve core to open the bypass valve of its own equipment, so that the lubricating oil enters the cooler for cooling (if the temperature measured by the temperature sensing element is higher, the bypass valve opens The greater the value), the cooled lubricating oil will return to the main engine.

　　The temperature control valve occupies a very large position in the control system. It controls the cycle of the screw air compressor. The control air compressor without the temperature control valve will not work. It can reduce energy consumption, reduce the load on the oil circuit, and reduce the deterioration of air compressor lubricating oil.
