Formula system, preact system.In design for fire protection, 4 degrees Celsius of Work places or building are generally lower than in a Nian Zhongyou temperature
Middle outfit is dry type or preact spray system, and quick response is needed to reach the place of water spray purpose, generally requires installation
Be preact system.In preact system, the gas that needs to keep having 0.3 ~ 0.4MPa in pipeline constantly above preact valve group
It presses (according to design for fire protection).We generally just need to keep air pressure in pipeline using air compressor machine in this way, and compressed air enters pipe
Water can be gradually appeared in road, most of water can be released by conduit slope by end drainage position, and if it is under
Hang down formula spray head, and water can not be discharged in main pipeline to the pipeline between spray head.
Sometimes, we go out water-responsive in order to verify spraying system of fire fighting reliability or in order to test spraying system of fire fighting
Time will do it water outlet test；Or due to wrong report, dry system, preact system pipeline inside water-filling.Same reason, such as
Fruit is droop spray head, we will be unable to discharge main pipeline to the water between spray head.
In winter, since most area outdoor temperature is lower than 0 degree Celsius, positioned at corridor, the workshop without warming installation, storehouse
If, which there is ponding the fire-fighting spraying head position in the low temperature such as library, underground garage, basement, accessory occupancy place, will will lead to pipe
Road freezes, so that fire-fighting spraying head bursting by freezing or injector seals component is freezing weeping occurs when spring weather gets warm again after a cold spell.
Currently in order to solving pipeline water phenomenon, typically front dump lower nozzle is drained in winter, so not only work
Work amount is big, and is easily damaged spray head or causes to do over again due to poorly sealed after installing again.
