A brief introduction to the type and structure of the air compressor intake valve. When it comes to air compressors, the most familiar to those who know it should be the brand, the operating principle of the machine and the overall structure of the machine. Then about piston air compressors and screw air compressors How much do you know about the contents of the intake valve? Today I'm going to tell you all about it in detail!
1. Piston intake valve: The up and down action of the piston in the intake valve of the air compressor is used to control the work of the air compressor empty heavy truck. When the air compressor is started, stopped and no-load, the discharge solenoid valve uses the air inlet to supply air to the piston, so that the piston is closed upwards.
When the air compressor works at full load, the discharge solenoid valve is energized to stop discharging, the piston chamber is discharged from the exhaust port, the piston of the intake valve drops due to the difference in intake pressure, the intake valve is fully opened, and the air compressor is fully loaded Work; when the pressure reaches the upper limit of the set pressure, the discharge solenoid valve loses power and starts to discharge, and pushes the intake valve piston up, so that the intake valve is in a closed state, and the air compressor is in an no-load state.
The structure of the piston intake valve is composed of an intake port, a valve cover, a piston, a base, and a discharge solenoid valve.
2. Butterfly intake control valve: When the screw air compressor starts, the intake valve is closed to ensure that it starts without load. When the motor is running under heavy load, the three-phase solenoid valve is turned on after being powered on, and the gas coming from this is fed into the servo cylinder of the intake valve, which pushes the valve stem of the servo cylinder, drives the intake butterfly valve, makes it fully open, and begins to reload. load operation.
The {C}{C}{C} single pendulum check valve inside the butterfly air intake control valve has its own counterweight and fluororubber sealing ring. The check valve can be closed quickly and tightly to ensure that there is no oil spitting during shutdown. The opening and closing of the butterfly valve is controlled by hand to control the cylinder. According to the received pressure signal and the inverse proportional valve, the depth of the piston rod of the cylinder can be controlled, and the butterfly valve can be opened or closed to adjust the air intake of the screw air compressor.
The structure of butterfly intake control valve consists of valve body, single pendulum check valve, butterfly valve and servo cylinder.
