RXXF series pressure relief device is mainly composed of form, window blade and so on. The pressure relief device is installed on the outside wall of the building and closed at normal times. When the fire extinguishing system releases the extinguishing agent, the pressure in the fire extinguishing area rises, and the pressure difference between the inside and outside the window blades of the pressure relief device is formed. When it reaches a certain value, the window blades are pushed to open, so as to maintain a certain concentration of the fire extinguishing area and protect the maintenance structure from damage. According to the requirements of the code, different building Spaces need different pressure relief areas of pressure relief devices. The pressure relief area can be calculated according to the compressive strength of the envelope structure of the fire extinguishing area, the injection rate of fire extinguishing agent and the specific coefficient. By adjusting the pressure relief area control mechanism, the required effective pressure relief area can be obtained to meet the engineering needs.
