1) ejector through walls can realize high-speed motion moment and penetrate body of wall；
2), after ejector through walls penetrates body of wall, ejector front end through walls nozzle ejects heavy pressure fine spray。
Wherein step 1) realizes in the following ways: ejector through walls adopts the version of similar hydraulic jack, ejector high velocity jet entrance through walls is connected with high pressure pumping source, and a high pressure accumulator and sequence valve are set between, high pressure accumulator accumulates the water under high pressure with certain pressure and flow gradually, when pressure rises to the unlatching pressure of sequence valve, sequence valve turns on, the water under high pressure with certain pressure machine flow that now abrupt release is accumulated by high pressure accumulator, the water under high pressure of high-pressure hydraulic pump output simultaneously also can collaborate the input high velocity jet entrance to ejector through walls, the internal piston bar driving ejector through walls is gone out forward at a terrific speed, in order to break through body of wall。
Wherein step 2) realize in the following ways: ejector high-pressure water inlet through walls is connected with high-pressure hydraulic pump, and ejector front end through walls arranges the nozzle that can form water mists。
The method have the advantages that and fire fighter can be made when not entering the scene of a fire; realize fire extinguishing through walls; it is effectively protected the safety of fire fighter; and without extensive damage body of wall or window; fire in building inner sealing space can be completely cut off with outside air; under the dual extinguishing mechanism efficiently cooling down and quickly suffocating of water under high pressure water mists, it is possible to put out rapidly the condition of a fire。
Accompanying drawing explanation
Fig. 1 is the systematic schematic diagram of the present invention
Detailed description of the invention
The invention provides a kind of high speed thin water spray fire-extinguishing method through walls, in order to make the object of the invention, technology path become apparent from, clearly, below in conjunction with accompanying drawing and embodiment, the present invention is described in more detail。
The present embodiment is a kind of high speed thin water spray fire-extinguishing method through walls, referring to Fig. 1, the present embodiment includes high-pressure hydraulic pump 1, bi-bit bi-pass solenoid directional control valve 1, water tank 1, bi-bit bi-pass solenoid directional control valve 24, high pressure accumulator 5, sequence valve 6, bi-bit bi-pass solenoid directional control valve 37, water tank 28, ejector through walls 9, connects each through pipeline between them。
The method of the present invention comprises the following steps:
1) ejector through walls can realize high-speed motion moment and penetrate body of wall；
2), after ejector through walls penetrates body of wall, ejector front end through walls nozzle ejects heavy pressure fine spray。
Wherein step 1) realizes in the following ways: ejector through walls adopts the version of similar hydraulic jack, it includes ejector cylinder through walls, internal piston bar, high velocity jet entrance and high-pressure water inlet, ejector high velocity jet entrance through walls is connected with high pressure pumping source, and a high pressure accumulator is set between and sequence valve high pressure accumulator accumulates the water under high pressure with certain pressure and flow gradually, when pressure rises to the unlatching pressure of sequence valve, sequence valve turns on, the water under high pressure with certain pressure machine flow that now abrupt release is accumulated by high pressure accumulator, the water under high pressure of high-pressure hydraulic pump output simultaneously also can collaborate the input high velocity jet entrance to ejector through walls, the internal piston bar driving ejector through walls is gone out forward at a terrific speed, in order to break through body of wall。
Wherein step 2) realize in the following ways: ejector high-pressure water inlet through walls is connected with high-pressure hydraulic pump, and ejector front end through walls arranges the nozzle that can form water mists。
Referring to Fig. 1, its operation principle of the present invention and process are as follows: when off working state or high-pressure hydraulic pump 1 are in unloading condition, and bi-bit bi-pass solenoid directional control valve 1 obtains electric, and high-pressure hydraulic pump 1 outlet is connected with water tank 1 through bi-bit bi-pass solenoid directional control valve 1；Carry out ejector through walls when spraying forward at a high speed, bi-bit bi-pass solenoid directional control valve 1 must not be electric, bi-bit bi-pass solenoid directional control valve 24 obtains electric, bi-bit bi-pass solenoid directional control valve 37 must not be electric, the water under high pressure of high-pressure hydraulic pump 1 output enters high pressure accumulator 5 through bi-bit bi-pass solenoid directional control valve 24, high pressure accumulator 5 accumulates the water under high pressure with certain pressure and flow gradually, when pressure rises to the unlatching pressure of sequence valve 6, sequence valve 6 turns on, the water under high pressure with certain pressure machine flow that now abrupt release is accumulated by high pressure accumulator 5, the water under high pressure of high-pressure hydraulic pump 1 output simultaneously also can collaborate the input high velocity jet entrance 10 to ejector 9 through walls, the internal piston bar 11 driving ejector 9 through walls is gone out forward at a terrific speed, in order to break through body of wall or window, owing to speed is exceedingly fast, and impact front end employing drill-shape, thus without extensive damage body of wall or window, the pore size gone out is close with the external diameter of ejector through walls, meanwhile, the high-pressure water inlet 12 of another road water under high pressure input extremely ejector through walls of high-pressure hydraulic pump 1 output, and through the nozzle of injector interior runner through walls and front end, high pressure spray injection forms water mists。Extinguishing operation is complete need to retract injector interior piston rod through walls time, bi-bit bi-pass solenoid directional control valve 1 must not be electric, bi-bit bi-pass solenoid directional control valve 24 must not be electric, bi-bit bi-pass solenoid directional control valve 37 obtains electric, now the internal piston bar of ejector through walls is under the counteracting force of front end high water injection, is retracted to rapidly initial position。
In order to verify feasibility and the effectiveness of technical solution of the present invention, do following experiment:
1) in November, 2012, waste and old factory tested in Hangzhou。Owing to the product of this inventive method and correspondence can more be applied on high-altitude fire fighting truck, therefore, during our simulation experiment, fine spray extinguisher through walls for the high speed developed is arranged on a jib。Systematic parameter such as table one of high speed fine spray extinguisher through walls, obtains result parameter referring to table two through experiment test。
