The Air Intake Control Valve Unloading Valve for Screw Air Compressor Parts Aiv-40 AIV-40 A-K AIV-40C-K AIV-40B-k
The inlet valve is the breathing port of the air compressor. After ordinary air enters the inlet valve, it goes to the compressor head and generates compressed gas after compression. It can control the loading and unloading of the air compressor and the size of the pressure flow and other functions, is a main part of the air compressor (intake control system).
The working principle of intake valve:
intake control valve is mainly composed of valve body, valve, piston, cylinder, spring, sealing ring and so on. Its side is equipped with control block and control solenoid valve, which integrates the functions of on-off adjustment, load reduction, muffler, step-down and shutdown. When reducing the load, a small part of the gas is released through the small hole in the valve to balance the suction volume of the inlet control valve small hole, so that the pressure in the separation tank is maintained at 0.2-0.3mpa, and the normal air compressor oil cycle is maintained. The opening and closing action of the intake control valve is automatically controlled by the pressure sensor and solenoid valve of the regulating system. Whether the opening and closing action of the intake control valve is flexible is very important to the reliability of the screw machine.

Screw air compressor inlet valve working process:
1.Start. The motor starts, the main engine starts to run, the inlet valve is closed and the air enters the small hole on the spool. The compressed oil and gas enters the oil and gas barrel, and the system pressure gradually rises.
2.Loading. Star triangle conversion, control system (pressure switch) will be the actual pressure and setting, when the system pressure below the pressure switch setting threshold pressure, pressure switch action make loading solenoid valve (three-way solenoid valve), electric three-way solenoid valve open, gas supply to the inlet valve servo cylinder push open the butterfly valve control cylinder, intake valve fully open breath; The pressure of the solenoid valve is closed at the same time, the machine is not empty, and the pressure in the tank continues to rise to supply air to the outside.
3.Royal loading. When the pressure rise to differential pressure switch online pressure, differential pressure switch sends an electrical signal to the astigmatic solenoid valve, solenoid valve end to close the inlet valve servo cylinder gas supply, control of cylinder hole inlet is not affected by the butterfly valve closing, maintained and controlled by the weight at this time check timely tameness tightly closed, open the drain valve at the same time to release the pressure in the barrel of oil and gas to basic oil pressure. The air compressor is in no-load operation, and after the electromagnetic valve is continuously powered off for 20 minutes, the system enters the empty car stopping state for too long.
4.Volume adjustment. Air compressor in the loading process to decrease the number of empty heavy load for air compressor, equipped with inverse proportion valve, when the unit pressure reaches maximum pressure switch inverse proportion valve in advance before action, reduce the gas to the servo cylinder, intake valve stem servo cylinder thrust reduction, under the action of spring force, the valve stem retraction, when the spring with the gas cylinder thrust balance out, the valve stem in a state of half open, The capacity of air compressor can be adjusted by reducing the intake volume. (5) Shutdown. Stop signal comes from empty car too long or the system pressure is in the upper limit of pressure for a long time, the store stops, the main engine stops spinning and no longer inspirates, and the relief valve continues to vent to the external atmospheric pressure.
Tips:
This is only a part of the part numbers, many oil separator filters P/N are not listed, in addition there are replacements filters for many other air compressor brands.
Filters are part of the air handling system and can provide the clean compressed air needed to remove oil and impurities. It can be used not only in pneumatic systems and pneumatic tools, but also in food, pharmaceutical and other industries.
