water pumppressure sum needed for pressure, shower nozzle work needed for water main resistance, water distributor height need be greater than.Water pump 4 flow need be greater than maximum amount of water needed for rainfall.
In the present invention, shower nozzle 12 is solid shower nozzle, and shower nozzle 12 will carry out type selecting according to different raindrop size and raininess.The uniformity of rainfall is adjusted according to the set height h of shower nozzle 12 and shower nozzle angle theta, and service area is 3.14*h*tg (1/2 θ) in principle
2, the setting of nozzle position at utmost covers rainfall underlying surface area and not overlapping for principle with service area.The water yield of water distributor 11 mean allocation distributive pipe 8, the shower nozzle 12 simultaneously water distributor 11 installed will be uniformly distributed, and each shower nozzle 12 arranges switch for regulating the unlatching number of shower nozzle 12, controls raininess.
In the present invention, switch 2 is used to control the water outlet of water butt 1 and water distributor 11.
In the present invention, articulation 10 is used to be convenient to installation and removal at water distributor 11 and distributive pipe 8 junction.Distributive pipe 8 is effectively separated with water distributor 11 by support 13, is convenient to install, and is not easy to leak
In the present invention, windshield 14 object prevents wind from producing power to raindrop, and fan housing 14 can be flexible material, and also can be profile material material, itself and support 13 be fixed, and fan housing 14 highly must be greater than shower nozzle 12 place height.
In the present invention, control shower nozzle 12 quantity by the switch of laid out in parallel on water distributor 11 and regulate.
Beneficial effect of the present invention is:
1, by arranging 1 control valve at return pipe, and manometer is set at distributive pipe.Met the water yield supplied water by the adjustment of circling water flow rate size, such regulative mode is little but achieve the adjustment of shunt volume size on the impact of the service behaviour of pump.Carry out by manometer the size that indirect reaction goes out output, cheaply facilitate again, and the pressure loss is less.
2, support system is effectively separated with water system, installs so in the wild, overhaul conveniently, and be not easy to leak.
