Abstract

The invention discloses a pressure-differential controlled air supply outlet, which is provided with an air outlet shutter at an air outlet. The pressure-differential controlled air supply outlet is characterized in that an air supply channel on the back of the air outlet shutter is provided with an electric actuator, the electric actuator is connected with a connecting rod moving along the vertical motion by a connecting arm, the connecting rod is pivoted with a plurality of connecting arms at a certain interval, and a regulating valve is fixed on the other ends of the connecting arms; and the electric actuator is also equipped with a pressure differential sensor for converting pressure differential signals into electrical signals and then transmitting the electrical signals to the electric actuator. The pressure-differential controlled air supply outlet disclosed by the invention replaces the existing positive-pressure intensity control methods such as excessive pressure valves or fan bypasses and the like in the existing pressurized air supply system for civil buildings; and by using the pressure-differential controlled air supply outlet, the system design is simplified and the cost is saved while the requirements on normative design are satisfied.

Description

technical field [0001] The invention relates to the field of architectural design, in particular to a differential pressure control air outlet. Background technique [0002] If natural smoke exhaust cannot be adopted in the smoke-proof stairwell and its front room, fire elevator room front room or shared front room in the building, the smoke prevention measures of mechanical pressurized air supply should be adopted to make the air in these parts The pressure is higher than the air pressure in the fire area. In order to prevent the smoke from entering and consider that the force required for the evacuation personnel to push the door does not need to be too large, the national standard stipulates that when the door of the pressurized part is closed, a certain positive pressure value should be maintained, and the door opening should have a certain pressure when the door is opened. The wind speed can effectively block the smoke. In order to maintain the positive pressure of th...
