Air volume control valve is a common type of valve, which is widely used in various industrial and civil pipeline systems. In the clean room purification project, the air volume control valve is often used to adjust the branch pipe air volume of the fresh air system to achieve the mixed adjustment of fresh air and return air.
The air volume is controlled by adjusting the opening and closing angle of the valve blade. The valve adopts a closed structure, and the air leakage volume in the closed state does not exceed 2%. The manual valve adjustment mechanism is divided into a handle type and a worm gear type, and the air volume is adjusted by changing the opening and closing angle of the blades; the opening and closing angle of the blades of the electric valve is controlled by a motor. This air volume control valve has the characteristics of flexible operation, low noise, small leakage, wide working temperature range, reliable structure, safe and convenient use, etc., and is favored by major construction parties.
The air volume control valve is usually installed in the pipeline of the ventilation system or the air conditioning system. It can also be used to control the ventilation of the fire staircase to ensure that there is enough fresh air in the staircase in an emergency to prevent the spread of smoke and ensure the safety of personnel. Therefore, it is very common, and it is also one of the main references for the fire department to check the fire safety of the unit.
