11244474 Replacement Air Compressor Valves For CompAir

Product Description:

The temperature control valve is composed of a valve body, a spring, a valve core and a guide sleeve. The spool works by the principle of thermal expansion and contraction. The opening temperature of the valve core has been set by the manufacturer. Generally, the opening temperature of the valve core has many kinds: 68 degrees, 70 degrees, 71 degrees, 76 degrees, 83 degrees, 90 degrees, etc., depending on the manufacturer's design and use. . The temperature control valve generally has 4 ports: represented by letters, U R R1 E. U and R are connected to the inlet and outlet of the cooler, R1 is to the main engine, and E is to the oil and gas barrel. Principle of action: At low temperatures, the oil enters from port E and exits from port R1. After reaching the opening temperature of the temperature control valve, the oil enters from port E and exits U to R through R1 to the host.

The temperature control valve occupies a very large position in the control system. It controls the circulation 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 the air compressor lubricating oil.

The working principle of temperature control valve:

1.The working principle of the temperature control valve of the screw air compressor is the thermal expansion and contraction of the temperature-sensitive liquid.

2.When the temperature of the controlled medium changes, the volume of the temperature-sensitive liquid in the sensor expands or contracts. When the temperature of the controlled medium is higher than the set value, the temperature-sensitive liquid expands and pushes the valve core downward to close the valve, reducing the flow of heat medium; when the temperature of the controlled medium is lower than the set value, the temperature-sensitive liquid shrinks and the return spring pushes The valve core is opened to increase the flow of heat medium.

3.The screw air compressor temperature control valve controller has PI and PID adjustment functions, precise control, multi-loop control, and diverse functions. It can realize the control of fluid flow, pressure, differential pressure, temperature, humidity, enthalpy and air quality.
