AIR PRESSURE DETECT DEVICE OF DAMPER OPEN-CLOSING

摘要

This proposal detects the difference in air pressure between the fire place and the smoke control area when a fire breaks out, and supplies air to the smoke control area if the air pressure in the smoke control area does not reach a pressure difference greater than a certain value compared to the air pressure at the fire place. The air pressure detection device for opening and closing the damper (DAMPER) to prevent the smoke from the fire place to enter the ventilation area by opening the air supply dam wave to blow air into the ventilation area.;In this proposal, the pipes inserted into the left and right sides of the connector are connected to the ventilation area and the pipe line respectively connected to the room, and one side of the pipe line is attached to the shaft by the connecting rod, the left and right ends of the shaft are connected to the shaft After being inserted into the hole, it is securely rotated by bolts inserted into the flanges attached to the outside of the side wall, and the shaft is inserted with a sensing rod that detects rotation of the shaft and a bolt that acts as a reciprocating act. Air pressure rises when it occurs in the air conditioner and operates the switchboard through the pipe line, and at the same time, it detects the air pressure flowing into the smoke control area until the air pressure in the smoke control area is higher than the air pressure in the place where the fire occurred (indoor). The damper was opened to increase the air pressure in the ventilation area.
