The control and display functions of the welding air duct fire control equipment for the smoke prevention and smoke exhaust facilities are not perfect

According to the requirements of Article 6.3.9 in the standard GB50116-98: after the fire alarm system is determined, the air-conditioning supply at the relevant position of the galvanized air duct must be terminated, the electric fire damper should be turned off, and the feedback data signal should be accepted; The smoke prevention and exhaust system, fire smoke exhaust fan, smoke exhaust fire damper, etc. at the location, and accept their feedback data signals. In some engineering projects, it is not possible to systematically operate the smoke exhaust and fire dampers and air supply outlets in a system-by-zone manner, and some cannot accept their feedback data signals, and cannot reflect the opening and closing of various valves. Galvanized air duct specification pipeline network gas fire extinguishing system software without pneumatic smoke exhaust fire damper. Article 6.3.4.3 of GB50116-98 stipulates: 'In the period of the court, fire doors, windows and windows should be automatically closed, the ventilation and air conditioning engineering system software should be terminated, and the smoke exhaust and fire dampers at the relevant positions should be closed.' This stipulates that in the pipeline In the software of the gas fire extinguishing system, a pneumatic smoke exhaust fire damper must be installed to be linked with the fire safety control system. There is no role in some engineering projects. There is no remote operation of galvanized air duct equipment when the exhaust and smoke exhaust systems share air ducts. Some engineering buildings, villa basements and underground parking lots use the same air ducts as the exhaust and smoke exhaust systems. The cut-off valve in front of the smoke system machine is only manually operated on the spot, and the remote operation of the main control room cannot be completed. Usually, when the ventilator is working, the cut-off valve developed at the front end is open. In the event of a fire, someone needs to go to the spot to close it The shut-off valve in front of the centrifugal fan, which is very unspecific, immediately endangers the smoke prevention and exhaust system. Therefore, its shut-off valve is proposed to enhance the remote operation effect. System software linkage adjustment and maintenance management method Fire control valve and smoke exhaust fire damper are not a separate product of aluminum silicate fiber for smoke prevention and exhaust system in specific projects, but they are unique in all automatic fire alarm control systems. Different linkage logic sequences. Therefore, in order to ensure its full play in the fire protection facilities, before the acceptance of the system software project, it is necessary to carry out all-round adjustments according to the linkage regulations, so that the natural ventilation, central air conditioning and fire hydrant systems meet the standard requirements. After the acceptance of the project, full-time personnel are required to carry out planned daily maintenance and management methods to ensure that the oil circuit board is in all normal conditions and to give full play to its role in the function of aluminum silicate fiber in the smoke prevention and exhaust system.
