Zusammenfassung: | The irrigation head is particularly for plants in heavy ground by drip feed, being mounted on a fixed or moving pipe at ground level. It has a shank connected to the pipe and accommodating an interchangeable metering casing. The water is delivered through the latter at a pressure of below 5 and preferably below 2m. water gauge. The casing (3) is a prismatic or cylindrical one extending along its lengthwise axis, containing a throttle passage (5a, 5b) in the form of a spiral polygon reducing the water speed. One end of this passage is connected to a socket portion (6) connecting the shank to the casing while the other forms a drip-feed opening (7) discharging the water. |
