For preventing the too high adverse effect of bringing to air bag of temperature rise; between fire district and air bag, to hang safety curtain; to stop that flame and high-temperature gas spread to air bag; safety curtain is selected lightweight material both fire-resistant and that coefficient of thermal conductivity is low for use; for the protection air bag is not damaged, air bag must be placed on apart from 2～4 meters of safety curtain, can locate with a protecting wire net when it is laid; if only, can not use safety curtain for preventing the diffusion of gas or other pernicious gas.
In the tunnel of needs sealing, can select monolithic or combined type air bag for use according to the shape and the size of drift section, utilize aerating device, also available down-hole pressure air pipe is inflated, aerating device is made up of gasholder and jet aerator, gasholder is a dress liquefied gas in, the high pressure resistant steel cylinder of tyre controlled valve, in its exhaust ports reducing valve and sebific duct are housed, the jet aerator is formed by tubular mixing chamber and tubaeform diversion chamber assembly welding, the end cap that has air vent and nozzle is welded in the bell-mouthed big end of diversion chamber, the two ends of handgrip are welded in respectively on the barrel of diversion chamber and mixing chamber, during inflation jet aerator mixing chamber termination packed in the air bag air inlet port, open non retern valve, the nozzle of diversion chamber is linked to each other with the gasholder sebific duct, after opening the controlled valve of gasholder, bottle mesohigh gas is injected diversion chamber through reducing valve by connecting sebific duct and nozzle from exhaust opening, in diversion chamber, form negative pressuren zone, air is entered in the mixing chamber inflow air bag in the lump through inspiration of end cap air vent and jet, it is sturdy with wall to impel air bag to expand rapidly, the sealing scene of the accident, inflation is complete closes the controlled valve of gasholder and the non retern valve of air bag, unloads the jet aerator.
The utility model compared with prior art has following advantage:
1, sealing method is simple, and the material installation consumption is few, and installation rate is fast, good operation safety, and air bag is in light weight, energy is fire-retardant, antistatic, good sealing effect.
2, this device can be standing in roadway, can handle the condition of a disaster timely and effectively, reduces or avoid personnel's injures and deaths, ensures miner's life security to greatest extent.
3, adopt the jet aerator, can reduce the consumption of gasholder inner high voltage gas, increase aeration quantity, shorten inflationtime, reaching the purpose of rapid sealing,
The utility model has the following drawings:
Fig. 1 is that mine laneway rapid sealing device is arranged schematic diagram
Fig. 2 is a mine laneway rapid sealing apparatus structure schematic diagram
Fig. 3 is a jet aerator structural representation
Fig. 4 is a combined type air bag schematic diagram
