Claims

[Scope of utility model registration request]

In a damper configured to be rotatable around a damper shaft attached to one end, a packing disposed at the end edge of the damper and in contact with the valve body is configured to have a hollow ring-like cross-section, and the ring An opening is provided in one part of the shaped packing, and the opening is communicated with an air injection hole formed in the damper shaft attached to one end of the damper and the damper core shaft supported by the damper shaft. It is connected to a compressed air source via a stop valve, and furthermore, air release holes are formed at different positions in the axial direction of the damper shaft and the damper core shaft, and these air injection holes or air release holes are used to open and close the damper. An automatic air injection type high airtight damper characterized by being configured to be able to automatically communicate or shut off depending on the situation.
