Training simulation fire equipment valve box
Technical field
This utility model relates to a kind of training simulation fire equipment valve box.
Background technology
At present, outdoor simulated fire rehearsal construction project is mostly pure import Germany and Italian facilities, and igniter structure form is that air is the most hybrid with combustion gas.The plane burner simulated fire fuel of more than 1 all uses propane gas.Simulated fire ignition procedures;Lighter is lighted, plane fire fuel gas supply, light the propane fuel gas that plane burner sprays through current stabilization layer.Simulation flat flame is formed.Simulated fire examination person's field control is lighted or extinguishes.All processes uses remote control to control and has flame safety protection.The little environmentally safe of flame smog, because being that combustion gas fire is pollution-free to water vent almost without combustion residue, has accomplished environmental protection.But simulated fire flame form and real scene fire disaster flame have gap, the most fiercely.Equipment manufacturing cost is the most expensive.Domestic simulated fire equipment simulating fire ignition procedures;The combustion of lighter fogging oil shots, the supply atomization of plane burner fuel form, light first atomizer atomized fuel of plane burner closest approach firearm and gradually light the fuel oil that remaining atomizer sprays again with relay-type.Flame profile is completely close to real scene of fire flame.Its shortcoming;Having residual fuel oil to pollute draining during hot drill, lighter wind loading rating is not ideal enough, can meet simulation flat flame burning of igniting in the case of outdoor wind speed is less than 2 meters/S of light breeze power when training.It is obviously reduced once the on-the-spot wind speed of training more than 2 meters/S, lighter fuel oil flame or can not sustained combustion.Its main cause due to wind direction and wind velocity reason cause atomized fuel can not sustained combustion, after causing atomization, fuel oil spreads to around, and this phenomenon is breakneck.Even if lighter can form flame due to the impact of extraneous wind speed sometimes, ignition flame is obviously reduced, even if the atomized fuel of first atomizer ejection of plane burner can be lighted, fuel oil after being atomized due to remaining atomizer of wind direction effect has blowed to opposite side causes flat flame relay not ignite, and the most just can not form plane burning.Fuel particles ballooning after unlit atomization, causes the atomized fuel sprayed and fuel oil-gas to fill the air everywhere, and this phenomenon may cause uncontrollable large area fire, is breakneck.Also having other similar devices, there is also lighter energy by observation the least, the flame after lighting cannot be sprayed more than 1.5 meters/S lighter by testing ground wind-force more than gentle breeze speed, is also impossible to light simulation plane fuel oil fire.Natural conditions are required the highest.More than gentle breeze can not use, many lighters can not work again simultaneously, and fuel delivery mode uses again dispersion supply type, and fuel nozzle is atomized and imperfection.Internal structure complexity maintenance load is big, is nearly at semiparalysis state, does not has referentiability.
The simulation outdoor fire project fuel that Xinjiang fire-fighting army unit builds also is to select fuel oil.Lighter uses pure spark ignition simulation plane fire, owing to the ignition energy the lowest persistent period is short, and is again nude lighter, and this lighter caused by the geographical environment of Xinjiang absolutely not adapts in outdoor.Outdoor simulating training system for fire device can only manually be lighted a fire, the biggest to igniting people's danger.Being only used for lab simulation small-sized fire device to use, i.e. enable and light simulation flame in indoor, lighter is little to reuse.With Single Maintenance once.Simulating and use oil tray to add a certain amount of fuel oil more than 2 outdoor ground fire, pure vapo(u)rability combustion flame fire is formed, sparking mode, uses and manually lights.Simulated fire is not accomplished controlled, it is necessary to added fuel oil has all been burnt and could have been terminated, can not all burn even if burning terminates also to have 5-10% fuel oil, cause the residual fuel oil burnt the most completely to pollute draining.
Summary of the invention
The purpose of this utility model is to provide a kind of training simulation fire equipment valve box, it is possible to ensure the normal table work of lighter, it is ensured that using effect.
The purpose of this utility model is realized in, a kind of training simulation fire equipment valve box, including casing, water pipe, fuel pipe, compressed air hose and four bodys of Gas Pipe are installed in casing, one manual ball valve is installed on water pipe, the port of export of manual ball valve is respectively provided with the left and right body in order to junction point firearm and burner, respectively equipped with an electromagnetic valve on the body of left and right;It is sequentially connected in series on fuel pipe and manual ball valve and big electromagnetic valve are set, compressed air hose manually ball valve respectively connected big voltage-regulation voltage-stabilization valve and little pressure regulation pressure maintaining valve, and the port of export of little pressure regulation pressure maintaining valve is connected with described big electromagnetic valve outlet pipe by electromagnetic valve and constitutes burner fuel outlet tube;The manual ball valve port of export on described compressed air hose is also connected with lighter air delivery pipe, lighter air delivery pipe is sequentially connected in series and arranges voltage-regulation voltage-stabilization valve and electromagnetic valve;Connect between both manual ball valves port of export on the manual ball valve of compressed air hose and Gas Pipe and burner gas supply pipe is set, small one and large one two electromagnetic valves it are respectively mounted on the port of export both sides body of gas supply pipe, little electromagnetic valve therein is cascaded with described big voltage-regulation voltage-stabilization valve, and the manual ball valve port of export in Gas Pipe is connected to lighter gas supply pipe also by a voltage-regulation voltage-stabilization valve.
In order to individual valve safe operation and maintenance prevent electric shock accidents from occurring, all field control components and parts all use safe voltage DC24V.Total system independence multiple grounding.Total system fuel valve reliable in action is sturdy and durable without static leakage, and has forward and reverse No leakage value more than 0.6Mpa plunger type electromagnetic valve.Open or close in order to all system electromagnetic valves are the most accurate, the detection of whole system igniter flame, burner flame detection, normal fault-signal feedback.Field control, remote controller control, remote control room controls, fault self-diagnosis, are all automatically controlled by programmable controller PLC.Attachment structure described in this utility model valve box is exclusively used in the supporting igniting operation of training simulation fire equipment, it is possible to ensure the normal table work of lighter, it is ensured that using effect.
