ELASTOMERIC EMITTER AND METHODS RELATING TO SAME

摘要

An irrigation drip emitter, and methods relating to same, are provided for delivering irrigation water from a supply tube to an emitter outlet at a reduced and relatively constant flow rate. The emitter having at least one movable member for compensating for fluctuations in supply line fluid pressure. In one form the movable member includes a tapered baffle section movable between a first position wherein fluid is allowed to flow over the tapered baffle section and a second position wherein fluid is prevented from flowing over at least a portion of the tapered baffle section and the tapered baffle section effectively lengthening the extent of a pressure reduction passage. In another form, first and second movable members are provided for compensating for such pressure fluctuations. In another form, a plurality of inputs are provided which are movable between first and second positions to compensate for such pressure fluctuations.

主权项

1. A method of assembling an irrigation drip line comprising:
providing a drip emitter comprising a discrete elastomeric emitter body integrally defining: an inlet on a first side of the body for receiving pressurized fluid from a fluid supply source; an outlet on a second side of the body for discharging the fluid from the body; a flow channel extending between the inlet and the outlet and having a pressure reduction portion having a plurality of non-tapered baffles and a pressure compensation portion having at least one tapered baffle; extruding a drip line tube; and inserting the drip emitter into the drip line tube as it is extruded such that the non-tapered baffles bond with an inner surface of the extruded drip line tube to form a sealed engagement so that the pressure reduction portion is enclosed and the pressure compensation portion remains movable with respect to the drip line tube.
