Detailed Description
The spiral-flow type fire-fighting lance is composed of a connector 1, a control ball valve 2, an assembly cylinder 3, a lance nozzle 4, an acceleration cylinder 5 and a spiral-flow impeller 6 (see the attached figure 1 of the specification); the method is characterized in that: one end of the assembling cylinder 3 is in threaded connection with a control ball valve 2; the control ball valve 2 is standard equipment purchased, and can be opened or closed quickly when a handle of the control ball valve is rotated.
One end of the control ball valve 2 is in threaded connection with a connector 1; the connector 1 is cylindrical, and a plurality of clamping blocks 17 are uniformly distributed on the circumferential surface of one end of the connector 1; the circumferential surface of the other end of the connector 1 is provided with a connecting thread. During operation, this spiral-flow type fire-fighting lance can connect soon with the one end of fire hose through joint block 17 fast.
The other end of the assembling cylinder 3 is in threaded connection with an accelerating conical cylinder 7; because the fire water can be spout through accelerating the gun nozzle 4 at awl section of thick bamboo 7 terminal during operation, consequently when setting up it and be the toper type, can reach the purpose of reinforcing pressure and increase velocity of flow through the mode that reduces the restriction area.
An assembly ring 12 is fixedly arranged in one end of the acceleration cone 7; one end of the accelerating conical cylinder 7 is connected with a gun nozzle 4 through threads; a swirl impeller 6 is clamped and fixed between the gun nozzle 4 and the mounting ring 12 (see the attached figure 4 in the specification).
The rotational flow impeller 6 is of an integrated structure (see the attached figure 3 in the specification), and consists of a mounting column 8 and rotational flow blades 9; the circumferential surface of the mounting column 8 is spirally provided with a swirl vane 9; one end of the mounting post 8 is conical. The swirl impeller 6 is arranged in this way for the purpose; so that during operation, the fire fighting water can uniformly enter between the swirl vanes 9 through the conical surface of the mounting column 8, and under the guidance of the swirl vanes 9, the fire fighting water can be sprayed out from the gun nozzle 4 in a "swirl" state.
The inside of the fitting cylinder 3 is provided with a fitting flange 10; a pressure build-up conical surface 11 is arranged in the assembling cylinder 3 on one side of the assembling flange 10; the purpose of setting the pressure building conical surface 11 is as follows: when the fire-fighting water passes through the pressure-building conical surface 11, the pressure and the flow speed of the fire-fighting water are enhanced under the action of reducing the flow area of the pressure-building conical surface 11.
The other side of the assembly flange 10 is provided with an accelerating cylinder 5 (see the description and the attached figure 1) in a threaded mode; the circumferential surface of the accelerating cylinder 5 is provided with a plurality of throttling straight holes.
A guide mandrel 14 is fixedly arranged in the accelerating cylinder 5 through a mounting disc 13; a sealing ring 16 is slidably mounted on the guide mandrel 14 through a buffer spring 15; the sealing ring 16 is intermittently sealingly connected to the mounting flange 10.
When the spiral-flow type fire-fighting lance works, the spiral-flow type fire-fighting lance is firstly connected with a fire-fighting hose through the connector 1 in a screwed manner; then the control ball valve 2 and the fire water source are sequentially started; after the fire-fighting water source is communicated, fire fighting can enter the fire-fighting lance along the fire hose.
After the fire water enters the fire-fighting lance, the high-pressure fire water extrudes the sealing ring 16 to enable the sealing ring to overcome the elasticity of the buffer spring 15 and move backwards, so that the fire water enters the acceleration cone 7 through the throttling straight hole. In the process, as the fire-fighting water flows into the accelerating cone cylinder 7 through the assembly cylinder 3 with a large flow area and the throttling straight hole with a small flow area, the fire-fighting water enters the accelerating cone cylinder 7 after the flow speed is increased under the action of the throttling effect.
The fire water entering the accelerating cone 7 is finally sprayed out from the gun nozzle 4 in a 'swirl' mode under the guidance of the swirl impeller 6; when the fire-fighting water is sprayed out in a 'swirl' mode, the spraying range of the fire-fighting water can be enlarged, and the contact area of a burning object is enlarged, so that the fire-fighting water is more easily vaporized, a large amount of heat is taken away, the burning object loses the temperature condition necessary for burning, and the purpose of controlling the fire spreading can be achieved.
In addition, when the fire-fighting lance works, fire-fighting water sequentially passes through the pressure-holding conical surface 11 of the assembly cylinder 3, the throttling straight hole and the throttling pressurizing of the acceleration cone cylinder 7, and the jet flow speed of the fire-fighting water is greatly increased compared with a common lance, so that the impact force of the fire-fighting water is improved, and the purpose of improving the fire-fighting efficiency is achieved.
The spiral-flow type fire-fighting lance has a compact structure and an ingenious design; the fire extinguishing efficiency of the fire-fighting lance is greatly improved by enhancing the flow speed and spraying the fire-fighting lance in a rotational flow mode; thereby meeting the fire extinguishing requirement of people.
