1. Piston-type intake valve: the use of air compressor intake valve inside and outside the piston movement control air compressor empty truck work. When the air compressor start, stop and no load, the discharge solenoid valve to use the air inlet to the piston gas supply, so that the piston shut down; when the air compressor full load work, the discharge solenoid valve power to stop the discharge, the piston chamber from Exhaust valve discharge, the intake valve piston due to the relationship between the inlet pressure drop, the intake valve fully open, air compressor full load work; when the pressure reaches the set pressure limit, the discharge solenoid valve power loss began to discharge, And push the intake valve piston, so that the intake valve is closed. At this time the air compressor was no-load state.
Piston intake valve structure has air inlet, valve cover, piston, base, discharge solenoid valve composition.
2. butterfly intake control valve: screw air compressor start valve when the valve is closed, to ensure that no load start. When the motor heavy load operation, the three-phase solenoid valve is turned on, then the gas into the intake valve servo cylinder, to promote the servo cylinder stem, driven by the butterfly valve, so that the full open, Load operation. Butterfly intake control valve internal single-pendulum check valve comes with counterweight and fluorine rubber seals, boot screw air compressor host suction, due to pressure reasons, the check valve can be promptly closed quickly , To ensure that there is no phenomenon of oil spill. Butterfly valve opening and closing control of the cylinder control, according to accept the pressure signal with anti-proportional valve can control the length of the cylinder piston rod length, butterfly valve open or closed, thus adjusting the screw air compressor intake.
The structure of the butterfly intake control valve consists of a valve body, a single pendulum check valve, a butterfly valve and a servo cylinder.
