Summary of the invention
The purpose of this utility model provides and a kind ofly can form tiny and measure the mesolow continuous heavy rain shower nozzle of big water droplet.
Mesolow continuous heavy rain shower nozzle described in the utility model has body, body top is provided with a central small hole and spiral water delivery groove, export department at central small hole and spiral water delivery groove forms hydraulic pressure release rotating drum, it is the taper guide wall that hydraulic pressure discharges the rotating drum bottom, the bottom is the continuous heavy rain spray orifice, the continuous heavy rain spray orifice connects camber and adheres to wall, and camber adheres to wall and connects taper continuous heavy rain dispersion wall, and body top is provided with the connection screw thread that is connected with feed pipe.
The utility model is to adopt the physical method of mesolow that press water is converted into to drip the intensive raindrop of shape, and makes it to carry out in the gas in container that high speed is numerous and diverse shuttles back and forth mobilely, impels gas and water to carry out powerful mixing.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: the 1-body, the 2-central small hole, 3-spiral water delivery groove, 4-connects screw thread, and 5-hydraulic pressure discharges rotating drum, the 6-guide wall, 7-continuous heavy rain spray orifice, the 8-camber adheres to wall, and the 9-continuous heavy rain disperses wall.
The specific embodiment
Below by embodiment the utility model is further described, the utility model is not limited to embodiment.
The described mesolow continuous heavy rain of present embodiment shower nozzle has body 1, connect with feed pipe with connecting screw thread 4, body 1 top is provided with a central small hole 2 and spiral water delivery groove 3, spiral water delivery groove 3 is a plurality of, water by spiral water delivery groove is because the effect of spiral, water is done rotation at a high speed in hydraulic pressure discharges rotating drum 5, the centre pressure of high speed rotating liquid obtains discharging, and the liquid of periphery since the effect of centrifugal force and pressure attached to discharging the rotating drum inwall, in the top, the uninterrupted propelling of low pressure water produces jet, and one of feature of jet is exactly attached wall phenomenon.
At the export department formation hydraulic pressure release rotating drum 5 of central small hole 2 with spiral water delivery groove 3, it is taper guide wall 6 that hydraulic pressure discharges rotating drum 5 bottoms, and the bottom is a continuous heavy rain spray orifice 7, and continuous heavy rain spray orifice 7 connects cambers and adheres to wall 8, and camber adheres to wall 8 and connects taper continuous heavy rain dispersion wall 9.
The jet of attached wall sprays along guide wall 6 circumferential centres, form fierce mutual shooting, ejection from continuous heavy rain spray orifice 7, adhere on the wall 8 attached to camber once more, the jet that adheres to readvances and collides continuous heavy rain dispersion wall 9, therefore jet is broken up a large amount of intensive raindrop of shape of generation, becomes circumferential work down hectare slant height speed numerous and diverse mobile.
The water of ejection also produces jet from central small hole 2, because in the center, therefore the pressure of circumference, flow velocity or the like phenomenon is consistent to the influence of this jet, its guiding is dripped the intensive raindrop of shape near inside to the circumference work hectare numerous and diverse mobile part of slant height speed and is flowed to the centre, create a numerous and diverse mobile intensive raindrop post of shape of high speed, effectively utilize powerful gas-water mixer inner limited gas, water blending space, improve the air content of gas, water mixing, facts have proved highly effective.
