As shown in fig. 1, in this embodiment, the fast fire sprinkler system mainly includes a liquid storage tank 7, a booster pump 6, a pressure stabilizing meter 5, a sprinkler head 1, an electromagnetic valve 2, a flame detector 3, and a control box 4. The liquid storage tank 7 is communicated with the booster pump 6 and the sprayer 1 through pipelines, and the pressure stabilizing meter 5 is arranged on the pipeline between the booster pump 6 and the sprayer 1. The booster pump 6, the voltage-stabilizing meter 5, the electromagnetic valve 2 and the flame detector 3 are all electrically connected with the control box 4. The equipment or tooling in the working area, where a fire may occur, is located in the spray area of the spray head 1. In this embodiment, the pressure in the conduit is brought to the desired range by injecting a fire fighting liquid, such as water or other fire fighting liquid, in the conduit between the booster pump 6 and the spray head 1; when the pressure in the pipeline is smaller than the lower threshold value set by the pressure stabilizing meter 5, starting the booster pump 6 to pump fire extinguishing liquid into the pipeline; when the line pressure reaches the upper threshold set by the pressure stabilizing gauge 5, the booster pump 6 is turned off. The line between the booster pump 6 and the reservoir 7 can be filled quickly. Because the pipeline between the booster pump 6 and the spray head 1 is filled with the fire extinguishing liquid with certain pressure, when a fire occurs, the liquid can be quickly sprayed to a working area, and therefore, the reaction speed is very high. When the liquid between the booster pump 6 and the spray head 1 is sprayed to extinguish a fire, the booster pump 6 continuously pumps the fire extinguishing liquid from the liquid storage tank 7 at the same time, thereby forming a continuous spray and achieving a rapid fire extinguishing.
In the embodiment, the liquid is arranged at the fire extinguishing end, namely, part of the pipeline in the pipeline at one end is preset with part of the liquid, and a certain time is reserved for extracting the fire extinguishing liquid. In an embodiment it is essential to use the space in the series line in exchange for the time of drawing the extinguishing liquid.
In a further embodiment, two parallel pipelines with one larger pipe diameter and one smaller pipe diameter are arranged between the liquid storage tank 7 and the spray head 1, and a pressure stabilizing meter 5 is arranged on the small-diameter pipeline between the booster pump 6 and the spray head 1 and is pre-filled with fire extinguishing liquid. The first booster pump 6 and the second booster pump 6 are respectively installed on the large-diameter pipeline and the small-diameter pipeline. The pressure of the small diameter pipeline is in an expected range; when the pressure in the small-diameter pipeline is smaller than the lower threshold value set by the pressure stabilizing meter 5, starting the first booster pump 6 and the second booster pump 6 to pump fire extinguishing liquid into the pipeline; when the small-diameter line pressure reaches the upper threshold set by the pressure stabilizing table 5, the first booster pump 6 and the second booster pump 6 are turned off. So that the pipe between the spray head 1 and the reservoir 7 can be filled quickly. Through the design of major diameter pipeline and minor diameter pipeline, the liquid in the minor diameter pipeline can be sprayed to the work area very first time, and second booster pump 6 draws fire extinguishing liquid through the major diameter pipeline afterwards. This design can be at ordinary times the less fire extinguishing liquid of storage, prevents the seepage. Can spray the liquid of putting out a fire to the work area fast through the small diameter pipeline, can spray the liquid of putting out a fire the very first time, simultaneously, another booster pump 6 can obtain certain time and draw the liquid of putting out a fire.
