Equipment consists of: pressure tank, regulator pump systems, cylinder systems, steam pumps, and automatic control systems. I produced a top pressure gas emergency standard fire pressure water supply equipment used for the GB / T50016 "architectural design code for fire protection" GA30.4 "performance requirements and test methods fixed fire water supply equipment - Part 4: Fire gas top pressure equipment." . The equipment consists of the pressure tank, regulator pumps, cylinders, automatic control systems and instrumentation valves, fittings and other components. This product has a number of new features, can be PLC programmable controller and touch screen system to automatically control, and fire control center networking: This device pressure tank comply JB150 "steel pressure vessel" and LB5099 seamless steel gas cylinders "requirement. The device can be equipped with dual power supplies and power outages start. This product is suitable for high-end clubs, hotels, restaurants, schools, museums, bath, and should not be set high water tank construction. 2 Overview of building fire water supply is often used to replace the high pressure tank water tank to meet the fire early 10min water, but often use an ordinary pressure tank to occupy a larger space. DLC Series Fire gas top pressure water supply equipment is GB / T50016 "architectural design code for fire protection"; to GA30.4 "fixed fire water supply equipment performance requirements and test methods - Part 4: Fire gas top pressure water supply equipment", Q / IFNM 9 "Fire gas of top pressure water supply equipment" fixed fire extinguishing equipment for new standards of production. The device consists of pressure tank, regulator device, container device, only gas installations, electric control system, etc., which is a common pressure tank tank volume 1/3 ~ 1/5, steady water pressure, is an ideal Large emergency fire pressure water supply equipment. 3 works complement the work of the water pump to the water supply network, the excess water into the pressure tank, when the liquid level reaches the set value SN3, the regulator pump stops working, then the system pressure does not reach the set pressure value, Regulators compressor starts running; when the pressure rises to the ceiling SP2 pressure regulator, the regulator air compressor will stop running. Because the system leaks and other causes of pipeline pressure drop, when the pipeline pressure drop to the lower pressure when the regulator SP1, if the level detector detects the set point value SN2 water, then repeat the regulator air compressor running; if liquid bit probe detects SN2 points less than the set value of water, then repeat fill the pump running, again and again. When the fire occurred firefighting equipment put into operation, the regulator device can not maintain pressure in the pipe when the pressure dropped to SP3 or fire control signal input, the gas pressure devices work top water into the top of the pressure tank fire control network, and to the tube 10min of the network to provide fire water. When the level drops to the set value SN1, turn off the gas only means to prevent the gas from entering the pressure tank fire control network. Equipment fire ended.
