摘要： Methods and apparatus for checking emitter bonds in an irrigation drip line and for manufacturing drip line in a manner that allows the bond between the in-line emitter and surrounding conduit to be checked. In one form, a downstream in-line vacuum tester is provided for monitoring the amount of air escaping from outlet openings in the drip line to detect excessive air associated with poorly bonded emitters.

摘要： An irrigation emitter and drip line, and methods relating to same, are provided for reducing the flow and pressure of fluid via an emitter or plurality of emitters defined by two concentric tubes. In one form, the first tube defines an emitter inlet and connected pressure-reducing flow channel and the second tube is extruded over the first tube to enclose the emitter inlet and flow channel and defines an outlet connected to an end of the flow channel opposite the inlet to create an emitter for converting fluid flowing at a high flow rate in the lumen and at the first end of the inlet to a fluid with a low flow rate at the outlet of the emitter. In another form, a drip line is provided having a plurality of such emitters. The emitters capable of being provided with pressure compensation structures to compensate or account for fluctuations in supply line fluid pressure and root growth inhibiting members. Various methods related to the emitter and drip line are also disclosed.

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 moveable member for compensating for fluctuations in supply line fluid pressure. In one form the emitter further includes a root growth inhibiting member for hindering roots from obstructing fluid flow through the emitter. In another form, the emitter includes an inlet protrusion so that fluid entering the emitter comes from a position closer to the central or center portion of the conduit in order to avoid larger obstructions that may be located near the periphery of the conduit. In another form, the emitter includes a carrier for assisting in mounting the emitter into conduit. In another form, more than one of the above features are present.

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.
