Pneumatic damper is a device that uses compressed air as a power source to control the opening, closing, or regulating of the medium flow rate through changes in air pressure. The following is a detailed introduction about pneumatic dampers:
Pneumatic damper, also known as pneumatic ventilation butterfly valve, is a device for controlling the flow of air or gas in pipelines by dividing and merging or switching the flow direction.
1. Open the intake valve. Close the intake valve
● 2. Open the single acting ventilation valve and close the shut-off valve
● 3. Display valve position open and closed
● 4, ⑤⑥ Feedback on signal ② ③ Feedback off signal
● 5. Adopting a 2-position 3-way solenoid valve
6. NL power on valve opens, power-off valve closes
Structure: Pneumatic dampers usually adopt a new structural form of welding midline disc plates and short structural steel plates, which is compact, lightweight, and easy to install. There are no connecting rods or bolts inside the body, making it reliable and with a long service life.
Type: According to different usage scenarios and functions, Pneumatic dampers can be divided into various types, such as regulating type, quick opening type, quick closing type, etc. Adjustable pneumatic dampers can receive signals from the system and adjust the opening of the valve based on the magnitude of the signal; Quick opening and quick closing pneumatic dampers are suitable for situations that require quick opening or closing.
