Fire Protection System Function

Hangzhou JWG Technology Co.Ltd | Updated: Jul 25, 2017

When a fire occurs, Fire Protection System the detector transmits the fire signal to the alarm controller, displays it through the acousto-optic signal, and displays the fire at the control panel to achieve the purpose of predicting the fire. At the same time, Fire Protection System you can also manually alarm button to complete the manual alarm function.

 The system is in normal working condition, the pipeline has a certain pressure of water, when a fire occurs, Fire Protection System the fire temperature reaches the temperature of the closed nozzle, Fire Protection System the glass bubble broken, nozzle water, the water in the pipeline from static to dynamic, Operation, the signal transmission to the fire control center fire control cabinet alarm, when the wet alarm device alarm, pressure switch action, through the control cabinet to start the spray pump for the pipeline water supply, Fire Protection System complete the system fire function.

Ductile iron pipe: suitable for automatic sprinkler system before the alarm valve buried pipe, fire hydrant system buried pipeline.

Welded steel pipe: Suitable for buried and overhead piping for fire hydrant systems and automatic sprinkler systems and water spray systems. Buried and overhead piping for the delivery of low pressure fluids.Fire Protection System  According to the wall thickness can be divided into ordinary steel pipe and thickening. According to the different process can be divided into ordinary welded steel pipe and hot dip galvanized welded steel pipe.

Seamless steel pipe: suitable for the main pipe or the lower part of the system working pressure higher parts of the pipeline. According to the different process can be divided into hot and cold rolling two.

When outdoor fire for life, fire combined with piping system or low pressure fire water supply system, you can choose to allow low pressure bearing pipe ductile iron pipe, welded steel pipe, Fire Protection System hot and cold galvanized steel pipe inside and outside, and PE water pipe.

When the outdoor fire water supply system for the temporary high pressure or high pressure water supply system, and the system working pressure is low, Fire Protection System the pipe can be used within the allowable pressure range (1) of the pipe; when the system's working pressure is large, Work pressure situation, respectively, Fire Protection System using ductile ductile iron pipe,Fire Protection System welded steel pipe, hot and cold galvanized inside and outside the ordinary steel pipe or thickened steel pipe and seamless steel pipe.

When the indoor fire hydrant system working pressure ≤ 1.0Mpa, can be used ordinary welded steel pipe, hot and cold galvanized inside and outside the ordinary welded steel pipe

When the indoor fire hydrant system working pressure of 1.0 ~ 1.6Mpa, Fire Protection System can be thickened welded steel pipe, hot-dip galvanized thickened welded steel pipe and seamless steel pipe.

Fire hydrant water supply system pipe When the use of internal and external wall hot-dip galvanized steel pipe, should not be used welding. System piping with anti-corrosion pipe wall can be used when the welding connection, but the pipeline welding should meet the relevant requirements. Automatic sprinkler system alarm valve can not be used after the pipeline welding, should be used thread, Fire Protection System groove type pipe fittings or flange joints.

Fire hydrant water supply system diameter greater than 100mm hot galvanized steel pipe, Fire Protection System should be used flange connection or groove connection. Fire Protection System Automatic sprinkler system pipe diameter greater than 100mm is not specified can not use the threaded connection, but requires pipe diameter ≥ 100mm in a certain distance on the allocation of flange connection or groove connection point.

Fire hydrant system and automatic sprinkler system piping in the use of flange connection should be used thread flange, when the use of welding flange should be secondary galvanized.

When any pipe section needs to change the diameter, Fire Protection System use the standard reducer fittings and fittings

The relevant provisions of the fire pipe connection and related technical requirements can refer to the "national civil engineering design technical measures - water supply and drainage" in the relevant provisions.
