Working principle of pressure relief port
SXYK series pressure relief mouth is mainly composed of form, shutter and so on. The pressure relief port installed in buildings, normally closed, when a fire extinguishing system fire extinguishing agent release area pressure, pressure venting window leaf air pressure difference is formed, when reaches a certain value to drive the window leaves open, so as to maintain a certain regional fire extinguishing concentration and protection to maintain the structure from damage. According to the requirement of different architectural space need to vent the pressure relief area is different, according to the coefficient of injection rate of fire area retaining structure of the compressive strength and fire extinguishing agent and specific to calculate the pressure relief area, through the wall of the pressure difference between inside and outside pressure relief to get effective area to satisfy the needs of engineering, so as to ensure the the general export pressure relief.
