Description

Novel water-powder mixed spraying gun

Technical Field

The utility model relates to a novel water-powder mixing spray gun.

Background

The common movable fire extinguisher in the market at present is a backpack water mist fire extinguisher. The fire extinguishing system is light in weight, is portable to fire extinguishing teams or rescue teams, can quickly extinguish traffic accident fires, tunnel fires, mountain or ship fires and the like, does not need to search water sources or prepare water supply fire fighting hoses, can reduce damage to property as much as possible when fire is extinguished by using water mist for fire extinguishing, and has the same effective rate and effect indoors and outdoors. Its spray angle can reach 60 degrees, and it can be suitable for different fire-extinguishing strategies, besides, it can also control different spray time very flexibly.

According to reliable literature reports, the superfine dry powder is the fire extinguishing agent with the highest fire extinguishing efficiency in the existing known fire extinguishing agents, the average particle size of 90% of the fire extinguishing agents is less than 20 micrometers, the fire extinguishing concentration can reach 50g/m, and after the superfine dry powder is sprayed out by means of high-speed gas, the superfine dry powder can achieve a high-efficiency fire extinguishing effect and can be suspended in the air for a certain time. But has the disadvantages of being greatly influenced by the external environment and limited spraying distance.

The backpack water mist fire extinguisher system is combined with the superfine dry powder, the dry powder is driven by water flow, the spraying distance is farther, and due to the addition of the superfine dry powder, the proportional mixed spraying of the water and the superfine dry powder is realized, so that the fire extinguishing effect is better. The key equipment for realizing the mixed spraying of water and superfine dry powder is a water-powder mixed spraying gun, and the caliber of the water-powder mixed spraying device on the market is relatively large and is not suitable for a backpack portable device, so that the design and development of a novel water-powder mixed spraying gun suitable for a backpack fire extinguishing device are imperative.

Wherein: a spray head 1; the internal thread joint 2 of the cutting sleeve; a spray pipe 3; a powder spraying pipe 4; a water spray cutting sleeve ball valve 5; a powder spraying cutting sleeve ball valve 6; a pipe clamp 7; the external thread joint 8 is clamped; a handle 9; and a powder outlet 10.

Detailed Description

The invention is described in further detail below with reference to the accompanying drawings:

as shown in fig. 1, a novel water and powder mixing spray gun, including spray pipe 3, dusting pipe 4 and pipe clamp 7, pipe clamp 7 below is connected with handle 9, the rear portion of spray pipe 3 and dusting pipe 4 presss from both sides side by side in pipe clamp 7, 3 rear ends of spray pipe extend to pipe clamp 7 rear and are provided with the water inlet, 3 front ends of spray pipe are provided with shower nozzle 1, 4 rear ends of dusting pipe extend to pipe clamp 7 rear and are provided with into powder mouth, 4 front ends of dusting pipe penetrate in the spray pipe 3 of shower nozzle 1 rear and are provided with powder outlet 10, be provided with water spray cutting ferrule ball valve 5 on the spray pipe 3 behind powder outlet 10, be provided with dusting cutting ferrule ball valve 6 on dusting pipe 4.

The powder spraying pipes 4 are arranged above the water spraying pipe 3 in parallel side by side, and the front ends of the powder spraying pipes 4 are obliquely bent forwards and downwards and penetrate into the water spraying pipe 3. A cutting sleeve internal thread joint 2 is connected between the spray head 1 and the front end of the spray pipe 3. The water inlet of the spray pipe 3 and the powder inlet of the powder spraying pipe 4 are both provided with a clamping sleeve external thread joint 8. The front part of the powder spraying pipe 4 is obliquely bent forwards and downwards to form 45 degrees, and the front end of the powder spraying pipe 4 is inserted into the central part of the water spraying pipe 3. The connecting mode of the pipelines adopts the cutting sleeve connection, so that the processing technology is simple, and the pipeline connection is convenient; the water spraying pipe 3 and the powder spraying pipe 4 both adopt stainless steel fine drawn pipes with the wall thickness of 1, so that the overall weight is reduced; the two channels adopt pipe diameters with different sizes, so that the mixing ratio of water to superfine dry powder is about 9; the handle 9 is made of plastic materials, the appearance structure of the handle accords with the physiological bending when the handle is held by hands, and the comfort is excellent; the pipe clamp 7 component is made of aluminum alloy, the surface of the pipe clamp is anodized and is black, and the attractiveness and the strength of the pipe clamp are satisfactory; the 4 anterior segments of pipe that dusts are 45 bendings, insert central point through the slot type hole on 3 anterior segments upper portions of spray pipe, and both weld integratively, can form venturi effect like this, form the negative pressure at the tip of 4 anterior segments of pipe that dusts, more are favorable to mixing the effect of spouting.

The specific working principle is as follows: when the backpack fire extinguishing host is opened, the nitrogen pressure of 0.85 MPa reaches the rear end of the water spraying cutting sleeve ball valve 5 respectively, and when the water spraying cutting sleeve ball valve 5 is opened and the powder spraying cutting sleeve ball valve 6 is closed, water from the backpack fire extinguishing host passes through the cutting sleeve external thread connector 8, the water spraying pipe 3 and the water spraying cutting sleeve ball valve 5 respectively, and is atomized and sprayed out through the nozzle 1, so that the spraying fire extinguishing function of fine water mist is completed. When the backpack fire extinguishing host is opened, when the powder spraying ferrule ball valve 6 is opened and the water spraying ferrule ball valve 5 is closed, the superfine dry powder from the backpack fire extinguishing host respectively passes through the ferrule external thread joint 8, the powder spraying pipe 4 and the powder spraying ferrule ball valve 6 and then is sprayed out through the spray head 1, thereby completing the spraying fire extinguishing function of the superfine dry powder. And (3) opening the backpack fire extinguishing main machine to provide 0.85 MPa pressure, and when the water spraying cutting sleeve ball valve 5 and the powder spraying cutting sleeve ball valve 6 are opened simultaneously, mixing water and superfine dry powder from the backpack fire extinguishing main machine respectively through the paths, and finally spraying the water and the superfine dry powder through the spray head 1, thereby completing the mixed spraying fire extinguishing function of the water and the superfine dry powder.

The foregoing is only a preferred embodiment of this patent, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of this patent, and these modifications and substitutions should also be regarded as the protection scope of this patent.
