[0002] Air conditioning stop valve is the important valve for adjusting and controlling refrigerant flow in refrigeration air conditioning system, and the working principle of air conditioning stop valve is based on the precision cooperation of valve core and valve seat. When the valve is closed, the valve core closely adheres to the valve seat and prevents the refrigerant from flowing. When the valve is opened, a certain passage is formed between the valve core and the valve seat, allowing the refrigerant to pass through. By adjusting the position of the valve core, the cross-sectional area of the passage can be changed, thereby controlling the flow of the refrigerant.
