Xi'an heptafluoropropane fire extinguishing device dedicated pressure relief installation tips
Laminating process adopts unique planer structure, so no need to adjust the plane if change welding head. ISO standard stripe chips are applicable. Full auto glue system make the process of putting chips stable and precise. Alarm correctly if chips or adhesive tape run out. High precision of constant temperature could ensure the stable glue laminating process.

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 discharge 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.
Working Principle Xi'an Ruichang Electronics Co., Ltd. pressure relief port is mainly composed of forms, shutters and other components. The pressure relief vent is installed on the external wall of the building and is normally closed. When the fire extinguishing system releases the extinguishing agent, the pressure in the extinguishing area rises. The pressure difference between the inside and the outside of the pressure relief port leaf forms a pressure difference. When a certain value is reached, the window leaf is pushed open. In order to maintain a certain fire extinguishing concentration in the fire extinguishing area and protect the maintenance structure from damage. In accordance with the requirements of the code, pressure relief vents with different pressure relief areas are required for different building spaces. The pressure relief area can be calculated based on the compressive strength of the fire extinguishing area enclosure structure and the injection rate of the extinguishing agent and a specific factor, and the pressure inside and outside the wall can be calculated. The required effective pressure relief area was obtained to meet the engineering needs, thereby ensuring the universality of the company's pressure relief vents.
