Compared to the prior art the utility model the advantage is that：
1) water collection cap is set on whirl cylinder top, is first into water collection cap by the water of centrifugal filtration and filter screen, collect
Water cap has certain cubical content, more steady into the water in water collection cap, and the air carried secretly in water can fully emerge union
Gather top in water collection cap and discharged by air inlet and exhaust valve, reduce gas enter irrigate main pipeline and influence normal dropper or
Sprinkling irrigation.
2) air inlet and exhaust valve is provided with water collection cap spherical plate center, when being shut down to the water pump for irrigating main pipeline pump water,
Water collection cap inside produces negative pressure, air inlet and exhaust valve air inlet, it is possible to reduce water hammer effect is conducive to protecting to water pump and the impulsive force of pipeline
Shield water pump and pipeline.
3) filter screen is provided with inside whirl cylinder, screen pack is by bottom circular mesh sheet, the cylinder mesh sheet on circular mesh sheet top and circle
The annulus mesh sheet on cylinder mesh sheet top is constituted；The filter screen of this structure, first, filter area is increased, can effectively reduce
Filtration resistance；Second, ring rotation water stream channel is constituted between annulus mesh sheet and whirl cylinder, with guide functions；3rd, by
The current that water inlet pipe enters rotate around filter screen, are capable of the various impurity of auto-flushing filter deposited thereon, with self-cleaning filter
Net function, it is not necessary to frequent clean and replacing filter screen.
4) arc deflector and spiral deflector are set in whirl cylinder, and it has significant guide functions, is conducive to shape
Into the current of high speed rotation, heavy sand particles spiral rotating in the presence of deflector sinks, and increased and was centrifuged
Filter effect.
5) ratio of water inlet pipe and diameter of outflow tube is 0.5~0.8: 1, increases water inlet pipe water velocity, is conducive to
Whirl cylinder forms the current of rotation at a high speed, improves centrifugal filtration effect.
6) the utility model simple structure, it is cheap, can be widely applied to drip irrigation, micro- spray and sprinkling irrigation.
