Description
Technical field:
The utility model relates to a kind of fine spray extinguisher, particularly a kind of passenger car low pressure fine spray extinguisher.
Background technology:
Along with the development of China's automobile industry, city bus and intercity Freeway Development, increasing people select city bus and the trip of intercity bus, and this also is an important indicator of urban modernization degree.Because motorbus itself is the separate space of a relative closure when operation, and personnel are intensive, in case breaking out of fire or blast, consequence is hardly imaginable.Because the relative closure in passenger car space makes the passenger car fire have high danger, after the vehicle fire burning, temperature raises, and volume of air expands, increased pressure, and hot flue gas stream gathers, and very easily produces " Hong combustion ", causes the dead group of group to hinder accident.
The utility model content:
The purpose of this utility model is to provide a kind of passenger car low pressure fine spray extinguisher, can protect A, category-B fire place, is applicable to the occasion that various limited space personnel are intensive.
For achieving the above object, the design of this explanation is:
In passenger car, arrange the low pressure fine water mist fire-extinguishing system, after fire takes place, the thin water smoke that fire extinguishing system is sprayed can utilize vaporescence to absorb a large amount of combustions heat, simultaneously can shroud flame, block radiation heat, therefore can control the intensity of a fire in the very first time on fire, effectively reduce temperature in the compartment, avoid Hong combustion; Thin water smoke not only can reduce fire scene temperature, effectively controls the generation of flue gas, can not produce noxious material simultaneously, does not need complicated releasing process, can not damage personnel in the compartment.Thin water smoke can guarantee that to effective control of the confined space intensity of a fire occupant has the comparatively sufficient time to save oneself, and makes the rescue personnel have grace time to evacuate trapped personnel, launches the fire fighting and rescue action.
The utility model low pressure fine spray extinguisher, characteristics are that gas cylinder is fixed on the fluid reservoir limit, and the fire extinguishing pipe network is connected on the fluid reservoir, and fire extinguishing sprayer is connected on the pipe network.By each way solenoid valve control, magnetic valve is controlled by Fire extinguisher respectively in the keying of each shower nozzle.
When the breaking out of fire of passenger car certain, operating personnel start extinguishing device according to corresponding button on the conflagration area selection control panel, promptly start the bottle valve on the gas cylinder, and open the required switch electromagnetic valve of fire extinguishing.After starting magnetic valve and opening, gases at high pressure discharge through pressure-reducing valve from gas cylinder and drive extinguishing medium the fluid reservoir, the switch electromagnetic valve that extinguishing chemical is flowed through and opened under pressed gas drives, and the corresponding fire extinguishing sprayer of flowing through again sprays fine mist fire-fighting.
According to above-mentioned utility model design, the utility model adopts following technical proposals:
A kind of passenger car low pressure fine spray extinguisher comprises a gas cylinder, fluid reservoir, pipe network, shower nozzle and a controller, it is characterized in that:
1) described gas cylinder is placed in by the described fluid reservoir, and the bottle valve of this gas cylinder is communicated with the epicoele of this fluid reservoir through a pressure-reducing valve by air pipe;
2) described fluid reservoir top liquid outlet is connected described pipe network by liquid pipeline through a hand control valve;
3) described pipe network is arranged on the inner roof wall of the passenger car left and right sides, and described pipe network is communicated with along the vertical uniform a plurality of shower nozzles of the left and right sides, compartment inner roof wall, and described shower nozzle is a fine mist spray head;
4) on the described shower nozzle switch electromagnetic valve is arranged, described bottle valve also is a kind of magnetic valve, and described controller connects described switch electromagnetic valve and bottle valve by lead.
Above-mentioned shower nozzle has 4～12.
The press button identical with shower nozzle quantity arranged on the control panel of above-mentioned controller.The circuit structure of controller is: year battery 24V power supply of picking up the car is a working power, is connected the control magnetic valve of each shower nozzle respectively by the press button and the control relay of each parallel branch.Simultaneously, the bottle valve on the gas cylinder is connected the 24V dc supply by the control magnetic valve of each parallel branch with control relay.Described controller also has a stand-by power supply, and is in parallel with the 24V dc supply by another control relay.
The utility model compared with prior art, have following conspicuous substantive distinguishing features and advantage: the low pressure fine spray extinguisher that the utility model provides can be arranged separately in the passenger car, can spray the fine mist fire-fighting agent and put out a fire at the emphasis that takes the lead in of breaking out of fire zone in the compartment, also spraying the fine mist fire-fighting agent in the compartment entirely puts out a fire, its fire extinguishing less expensive, reasonable, effect is better.The utility model is simple in structure, and cost is low, is easy to apply.
