Installation precautions are as follows:
The pressure relief vent in the protective zone of gas fire extinguishing system refers to the device that automatically opens and releases pressure when the pressure value in the protective zone reaches the specified value when the extinguishing agent in the gas fire extinguishing system is sprayed. It is also referred to as the pressure relief vent, also called the auto relief pressure. Device. According to the characteristics of the gas fire extinguishing system, our company specially developed this type of pressure relief device. The area of ​​the pressure relief device can be adjusted according to the volume of the protection zone and automatically closed after pressure relief.
The need to open a pressure relief vent in the protection zone is due to the gas fire extinguishing agent sprayed into the protection zone, which will significantly increase the internal pressure in the protection zone. If there is no proper pressure relief vent, the protection zone of the protection zone may not be able to withstand the increase. The pressure was destroyed. For areas requiring tightness such as constant temperature and humidity, a normally closed pressure relief vent should be provided. Pressure relief vents should be open to more than 2/3 of the net height of the protected area. That is, the pressure relief vent should not be less than 2/3 of the net height of the protected area. The size of the pressure relief port, which is the function of the fire extinguishing agent spray rate used in the protection zone and the allowable pressure of the enclosure envelope structure to withstand the internal pressure, and the pressure relief port area can be calculated.
