鸿安国 standard fire hydrant fire hydrant SN65 \ 50 type indoor fire water supply pipe network to interface with the valve, as factories, warehouses, high-rise buildings, public buildings and ships and other indoor fixed fire-fighting facilities, usually installed in the fire hydrant box Fire wet alarm valve, with the fire hose and other equipment supporting the use of water cannons. Fire hydrant, is an important part of the fire water system, which is installed in the indoor fire box Jinyuan wet alarm valve, usually nominal diameter (mm): DN50, DN65 two kinds, nominal working pressure 1.6MPa, the strength test pressure 2.4MPa, Medium: clean quality water, foam mixture. Typically fire hydrant can be divided into common type, pressure regulator type, rotary type, etc., it is artificial fire way to plug the mouth with water en fire, in addition there hydrant hydrant box button, press this button can remotely start the fire pump supply water to the fire hydrant. ZSFG type rain rain alarm valve alarm valve Usage: rain alarm valve is set by supporting automatic fire alarm system or automatic transmission chain pipe systems or remote control, manual start, so that water can flow into the sprinkler system in one direction, while An automatic sprinkler system is an important device alarms, alarm systems are widely used in the rain, water spray system and water curtain system. Extinguishing Principle: In case of fire, automatic fire alarm system to detect fire and automatically open the solenoid valve, the diaphragm chamber pressure Min mountain water flows out wet alarm valve, diaphragm chamber pressure will therefore decrease when the pressure drops to a certain When the extent that the transfer arm fastening force applied to the valve assembly is less than the water pressure is applied to the valve assembly of the wet alarm valve, water valve assembly will be opened, the water will flow to the system side of the pipe network, and by the spray nozzle out of the fire, and start all kinds of alarm device. Product specifications and performance specifications: Model / performance ZSFG-100 nominal diameter mm 100 Rated working pressure MPa 1.2 startup time MPa t <15 friction MPa <0.07 Other models: ZSFG-150 ZSFG-200 Jinyuan wet alarm valve, ultra-safe Fire (certified), Jiangmen wet alarm valve provided by the Dongguan Nan ultra fire equipment operators.
