The role of the intake valve

A controllable valve used on the intake pipe to control the air entering the engine. After entering the intake manifold, it is mixed with gasoline to become a combustible mixture and participates in combustion to do work. Four-stroke gasoline engines are roughly the same. The throttle valve is a device on the intake system of the engine. It is a circular steel sheet with a shaft in the middle, which is controlled by the throttle cable to open and close.

How the intake valve works

1) The intake control valve is mainly composed of a valve body, a valve, a piston, a cylinder, a spring, a sealing ring, etc., and its side is equipped with a control block and a control solenoid valve, which integrates on-off adjustment, load reduction, noise reduction, pressure reduction and Shutdown and emptying functions.

2) When unloading, a small part of the gas is released through the small hole in the valve to balance the intake air volume of the small hole of the intake control valve, so that the pressure in the separation tank is maintained at 0.2-0.3MPa, and normal air compression is maintained. oil circulation.

3) The opening and closing actions of the intake control valve are automatically controlled by the pressure sensor and solenoid valve of the regulating system. Whether the opening and closing actions of the intake control valve are flexible is very important to the reliability of the screw machine.
