Description

A kind of twin shower nozzle

Technical field

The utility model belongs to the hydraulic sprinkler design and makes the field, is specifically related to a kind of twin shower nozzle.

Background technology

The twin shower nozzle is widely used in fields such as sterilization, fire-fighting, pesticide spraying.The multiinjector structure that existing twin shower nozzle adopts single injector or linear pattern to arrange more has the following disadvantages: (1) single injector spraying coverage is little, as thinks the use of wide scope, and on-the-spot pipe network consumption is big.(2) the mist momentum is little, often is difficult to overcome air drag and arrives the spraying object surface.(3) because existing nozzle generally adopts is principle with gas boosting water, dependence nozzle in forms negative pressure through nozzle to the air pressure jet-action of outside by air cavity and comes water in the liquid draw body cavity, after in nozzle, carrying out gas-vapor mix, rely on air pressure that water is ejected again, gas just plays the effect of boosting water merely, reach the droplet coverage effect of wider range as need, then need higher compressed air pressure and use amount, compressed air and amount of liquid that unit interval consumes are all bigger, also there are simultaneously nozzle and nozzle cavity pressure height, baroque shortcoming.

Summary of the invention

The purpose of this utility model provides a kind of wide coverage and high twin shower nozzle of spray momentum of spraying.

For achieving the above object, the utility model has adopted following technical scheme: a kind of twin shower nozzle, comprise nozzle, nozzle is more than one and is arranged in the shower nozzle front end, nozzle comprises and is positioned at its inner liquid flow hole and pore, liquid flow hole is exposed at end face outside the shower nozzle formation liquid outlet of postponing outside nozzle, described pore is exposed at end face outside the shower nozzle and postpones and constitute the gas outlet outside nozzle, liquid outlet and gas outlet are a plurality of and adjacent layout, shower nozzle is provided with inlet opening and air admission hole, between air admission hole and pore and between described inlet opening and liquid flow hole all by independently air cavity road or liquid flow cavity road are connected separately.

The beneficial effects of the utility model are: after adopting said structure, solved the problem that the spraying coverage is little and the pipe network consumption is big that existing gas pushes away water type shower nozzle, the design of a plurality of liquid outlets and gas outlet, water is not be used in mix in the nozzle back to push out by force with gas, thereby but produce water bag gas effect after directly water under high pressure, spraying high-pressure gas delivery nozzle being relied on gases at high pressure with the water flow-disturbing of ejection and gas-vapor mix outward water smoke is spread out again, form single shower nozzle and produce a plurality of double-current atomizing effects.Push away the water-bound shower nozzle with existing gas and compare, the utility model wide coverage can effectively reduce the friction between droplet, and the spray momentum height can obtain simple water atomizing effect under high pressure under lower pressure.
