Details

The intake valve is composed of valve body, rotary check valve, butterfly valve control cylinder. The rotary check valve is equipped with counterweight fluororubber sealing ring. When the compressor is started up, the main engine inhales air. Due to the pressure difference, the check valve opens rapidly. When the compressor is stopped, the pressure difference is lost controlled by the counterweight. The check valve can close quickly in time to ensure that there is no shutdown oil discharge. The opening closing of the butterfly valve are controlled by the control cylinder according to the piston extension length of the control cylinder , the butterfly valve is opened closed to adjust the air intake of the compressor.

Characteristics of wear

In supercharged four stroke diesel engine, with the increase of supercharging degree, the average effective pressure is higher higher, the wear of intake valve valve seat is more more serious. Therefore, more more attention has been paid to the wear of intake valve valve seat at home abroad. This problem is also encountered in a 12V180ZL diesel engine produced by a factory. After hundreds of hours of operation, only the valve seat is severely worn eccentric worn, but also the conical surface of the air valve is caused by serious grooves. In the most serious case, the wear is up to 2.38mm after 530 hours of operation.
