Drip emitter with an independent non-drain valve

摘要

A flat type pressure regulated drip emitter with a non-drain valve capabilities that is installable inside a water supply conduit during the conduit manufacturing process and characterized by that the emitter's non-drain valve function is executed independently and separately from its pressure regulation function, through a portion of the emitter's elastomer component that is strained and biased against the emitter's water inlet opening and is moveable towards and away from an additional opening (additional to the emitter's water outlet opening), exposed to the pressure prevailing in the emitter's water exit pool and therefore, at any given time, this portion of the elastomer component is exposed to the maximum differential pressure that prevails in the system—on its one side to the water pressure prevailing in the water supply conduit and on its other (second) side—to the approximate atmospheric pressure.

1. A flat type pressure regulated drip emitter with a non-drain valve capabilities that is installable inside a water supply conduit during the conduit manufacturing process and comprises:
a housing assembly comprising a water inlet opening; a cover component comprising a water outlet opening, the cover component adapted to being affixed onto said housing assembly and formed with the bottom of said emitter a water exit pool; and an elastomer component adapted to being affixed within said housing assembly and opposite said cover component; and wherein said emitter provides a water pressure regulating mechanism which through a throttle means together with said elastomer component for decreasing the pressure of the water that is passing through it; and characterized by the emitter's non-drain valve function is executed independently and separately from its pressure regulation function, through a portion of the emitter's elastomer component that is strained and biased against the water inlet opening to the emitter; and wherein said portion of the emitter's elastomer component is moveable towards and away from an additional opening formed in said cover component; and wherein said additional opening is an additional opening to the emitter's water outlet opening; and wherein said additional opening is exposed to the pressure prevailing in the emitter's water exit pool and therefore, said elastomer component portion is exposable on its one side to the water pressure prevailing in the water supply conduit and on its other (second) side to the approximate atmospheric pressure.
