Fire-fighting automatic pressure-regulating water supply device and using method thereof

Abstract

The invention relates to an automatic pressure-regulating water supply device for fire fighting, which comprises a pressure-stabilizing water storage tank, a pressure reflux meter, a safety valve, an opening control valve, a closing control valve, a water pressure regulator, a temperature regulating system and a water outlet control valve, an overflow port and a reflux port are formed in the side wall of the pressure-stabilizing water storage tank, and the overflow port is communicated with the reflux port through the pressure reflux meter; the water outlet is communicated with a safety valve through a flow guide pipe, the safety valve is further communicated with an opening control valve and a closing control valve, the opening control valve and the closing control valve are both communicated with a water pressure regulator through flow guide pipes, and the water pressure regulator is further communicated with a water outlet control valve. The using method comprises the three steps of equipment assembly, water storage pressurization and fire-fighting spraying operation. On the one hand, the requirement of being matched with a fire extinguishing system in various occasion environments for use can be effectively met; and on the other hand, the operation stability of the fire-fighting water supply system is improved, and the fault resistance is high, so that the purpose of improving the stability of fire-fighting water spraying operation is achieved.

Description

technical field [0001] The invention relates to an automatic pressure-regulating water supply device for fire-fighting and a use method thereof, belonging to the technical field of fire-fighting equipment. Background technique [0002] In recent years, the fire protection system, as an important part of the building fire protection system, has been widely installed and used in a large number of buildings. A large number of fire cases have shown that a sound and effective fire water supply system is one of the important means for timely fire rescue. It is of great significance to cause fire hazards, but it is found in actual work that when the current fire protection system is performing fire protection operations, the spray water pressure of fire protection water is often easily affected by factors such as water supply pressure fluctuations of water supply equipment, water supply equipment failures, etc. As a result, the efficiency of fire-fighting system spraying is serious...

Problems solved by technology

[0002]In recent years, as an important part of building fire protection systems, fire protection systems have been widely installed and used in a large number of buildings. A large number of fire cases have shown that intact and effective The fire water supply system is one of the important means for timely fire rescue, and it is of great significance to cause fire hazards. However, in actual work, it is found that when the current fire system is performing fire protection operations, the spray pressure of fire water is often very easy. Affected by factors such as water supply pressure fluctuations of water supply equipment, water supply equipment failures, etc., the efficiency of fire-fighting system spraying out of stock is seriously affected due to unstable water supply pressure and insufficient pressure when fire-fighting water is sprayed.
