"Civil water fire extinguishing system design rules" provides that:

    1, the system should be located fire pump. Fire regulator pump, fire tank should be set with the fire pump in the same fire pump room;

    2, the system should be located fire tank. The total volume of indoor fire hydrant water supply system should not be less than 50L, automatic sprinkler system should not be less than 50L, indoor fire hydrant water supply system and automatic sprinkler system fire pump and fire regulator tank water supply method should not be less than 80L ;

    3, fire pump regulator pipe diameter should not be less than 50 mm;

    4, no high-level fire water tank high pressure water supply system, the pipe network should be located in the highest parts of the automatic exhaust valve. Fire hydrant system should be 1 liter / second; fire hydrant water supply system and automatic sprinkler fire extinguishing system should be 5 liters / second, automatic fire sprinkler system should be 1 liter / second; fire hydrant system and automatic sprinkler fire extinguishing system System for the fire regulator pump should be 3 liters / second;

    5, steady high pressure fire water supply system of fire pump, the lift should be greater than the fire pump head. Use of high pressure fire water supply system indoor fire hydrant water supply system, the fire hydrant box may not have remote start its fire pump button, by the indoor fire hydrant system fire pump pressure linkage linkage to start its fire pump; The use of steady high pressure water supply system of automatic sprinkler system of its fire pump should be the fire pump pressure linkage linkage to start its alarm valve group pressure switch may not linkage fire pump. Fire pump regulator shut down and open the pressure linkage should be controlled. In the steady high pressure fire water supply system, the starting pressure value of the fire pump, the stop pump pressure value of the fire pump and the starting value of the linkage fire pump should not be less than 0.05 MPa.

When equipped with high-level fire water tank, the set value should be higher than the bottom of the tank to the most adverse point of elevation difference. Stable high pressure fire water supply system is a very unique fire water supply system, it is more than high-pressure fire water supply system reality, and than the temporary high-pressure fire water supply system in the most unfavorable point of water pressure is more assured, that is stable high pressure fire water The system is more reliable than the temporary high pressure fire water supply system.

In the field of fire has always been strict public buildings, residential construction from the broad principles of treatment. 10-story and 10-storey residential use of the temporary high-pressure fire water supply system and 7-9 residential double frequency constant pressure water supply system with a single fire control equipment, electrical control is simple, simple operation control, low operating costs, low investment and easy maintenance And the characteristics of the application of fire pump to maintain the pressure regulator pipe network, an increase of equipment operating costs, is not conducive to tenants.
