Introduction to inlet valve
The intake valve is composed of a valve body, a rotary check valve, a butterfly valve and a control cylinder. The rotary check valve comes with a counterweight and a fluorine rubber sealing ring. When the compressor is turned on, the main body of the compressor sucks in air. Due to the pressure difference, the check valve opens quickly; when it is stopped, the pressure difference is lost, and it is controlled by the counterweight to check The valve can be closed tightly in time to ensure that there is no stoppage of oil. The opening and closing of the butterfly valve is controlled by the control cylinder. According to the extension of the piston of the control cylinder, the butterfly valve opens or closes to adjust the compressor air intake.
