Embodiment Construction

[0033] A metered injection compressed air foam fire extinguishing system of the present invention and a method of using the same will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] like figure 1 As shown in the figure, a metering injection type compressed air foam fire extinguishing system, the first part is the foam liquid supply part, which mainly consists of a foam raw liquid storage tank 1, a tuning fork sensor 2, a foam pump 3, a single-phase check valve 4, and a foam flow meter 5. , consisting of 6 pneumatic three-way valves. The working state of the foam pump is controlled by the control system, and the speed of the foam pump 3 determines the mixing ratio of the foam mixture. After the ratio of the foam mixture is determined, the speed of the foam pump 3 changes with the flow of water Variety. The function of the tuning fork sensor 2 is mainly to monitor the storage volume of the foam stock solution in the f...

Abstract

The invention discloses a fire extinguishing system of a metering injection type compressed air foam and a method for using the same. A fire extinguishing system of a metering injection type compressed air foam includes a control and power supply part, a foam liquid supply part, a water supply part and an air supply part And the foam mixing chamber and the injection part; the present invention also discloses the use method of the fire extinguishing system, through which the system controls the reasonable mixing of air, foam stock solution and water, and sprays the foam mixture to extinguish the fire under the control system, and also increases the protection and pigging design; the present invention improves the reliability of the fire extinguishing system through reasonable system design, adopts positive pressure technology for foam mixing, solves the problem of short injection range, optimizes the control system, and adopts modular design for mechanical parts to improve the maintenance efficiency and quality.

Description

technical field [0001] The invention belongs to the technical field of emergency fire-fighting of power grids, in particular to a fire-extinguishing system of a metered injection type compressed air foam, and also relates to a method of using the fire-extinguishing system. Background technique [0002] Since entering the new century, human society has gradually entered the era of knowledge economy and network information in an all-round way. It is gradually discovered that ensuring the safety and stable supply of electric energy plays a very important role in daily life, so the importance of the power grid is also increasing day by day. The transformer is an important part of the power grid to ensure the normal supply of electric energy. Once the transformer fails to work normally or a fire accident occurs, it will bring unpredictable losses to the local economic development. [0003] If a fire accident occurs in the transformer in the power grid, that is, the oil tank belo...
