When the water film-forming foam extinguishing agent is sprayed to the burning oil surface, one side of the foam is scattered on the oil surface, and the other side of the foam forms a water film on the oil surface, so that the evaporation of oil products is inhibited, the oil products are isolated from air, and the foam is rapidly diffused to the area which is not directly sprayed to further extinguish fire. The aqueous film-forming foam extinguishing agent is suitable for low-expansion foam extinguishing equipment, is mainly used for general nonpolar combustible and flammable liquid fires, can quickly control the spread of the fires, and can be used together with a dry powder extinguishing agent.
3. Advantageous effects
Compared with the prior art, the utility model has the advantages of:
1. the utility model discloses in, each subassembly is the batch production processing preparation all, and the equipment is accomplished, and the complete set dispatches from the factory, and it can to fix a position the installation according to complete sets during the tunnel installation.
2. The water source water inlet pipe end is connected with a water source pipeline through a hoop, the foam liquid inlet end is connected with a stainless steel pipeline through the hoop or welded, and the mixed liquid outlet section is connected with a pipe network through the hoop, so that the quick installation of a valve group box and a pipeline of the tunnel foam water spraying system can be realized.
3. Because the tunnel is mainly used for automobile fuel oil and rubber fire, compared with the traditional water spray fire extinguishing system, the fire hydrant system and the fire extinguishing box which are independently arranged in the tunnel, the foam water spray fire extinguishing system valve set can rapidly control the spread of the fire, can timely and effectively control the tunnel fire through automatic control and signal feedback, and can be used together with the fire hydrant system and the fire extinguisher box in the tunnel.
