The reference answers can be seen after *replying*; points will be awarded for identifying the key points. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) It is an abbreviation for the compressor valve; it is a component of positive-displacement compressors that allows fluid to be drawn in and discharged in one direction while preventing backflow. There are intake valves and exhaust valves, and they serve as control mechanisms that enable the four processes of compression, discharge, expansion, and intake to take place sequentially within the compressor cylinder.

The air valve is an important component on the compressor cylinder, responsible for the intake and exhaust of gas. A traditional valve consists of a valve seat, valve disc, spring, lift limiter, bolts, etc.
The air valve is an important component on the compressor cylinder, responsible for the intake and exhaust of gas. A traditional valve consists of a valve seat, valve disc, spring, lift limiter, bolts, etc. The gas in the control cylinder is automatically drawn in when it reaches an appropriate pressure, and automatically discharged when it is compressed to an appropriate pressure.
On the compressor, there are valves used to adjust its load. The air valve is an important component of the compressor cylinder, responsible for the intake and exhaust of gas. It affects the compressor’s displacement, power consumption, and operational reliability.
The valve assembly used for pulse air supply inside the compressor cylinder is called an air valve. The function of the valve is to control the intake and exhaust of gas in the cylinder. The requirements for the air valve are: 1) The air valve should open and close promptly, and it must seal tightly to prevent air leakage when closed ； 2) The resistance loss is low when air flows through the air valve ； 3) Long service life of the air valve ； 4) The clearance volume formed by the air valve is small ； 5) Simple structure with good interchangeability.
It is an abbreviation for the compressor valve; it is a component of positive-displacement compressors that allows fluid to be drawn in and discharged in one direction while preventing backflow. There are intake valves and exhaust valves, and they serve as control mechanisms that enable the four processes of compression, discharge, expansion, and intake to take place sequentially within the compressor cylinder.
The air valve is an important component on the compressor cylinder, responsible for the intake and exhaust of gas.
Classified by function, air valves are of two types: intake valves and exhaust valves. They open due to the pressure difference between the working chamber of the cylinder and the valve chamber, and rise as a result of the thrust exerted by the airflow passing through the valve during the intake and exhaust processes； But when the thrust is greater than the spring reaction force, the valve disc remains on the lift limiter ； Conversely, when the airflow thrust is less than the spring force, the valve disc closes downward. The function of the gas valve can be summarized as controlling the automatic intake of gas into the cylinder at an appropriate pressure, and its automatic discharge when it is compressed to an appropriate pressure.
