摘要： A pressure regulator includes a housing assembly defining a main fluid flow path from an inlet end to an outlet end. A tubular plunger body is supported within the housing assembly for linear movement toward and away from a valve seat in response to fluid pressure at said outlet end. An actuator sleeve is supported within the housing assembly and engaged with the tubular plunger body, and a pressure chamber defined in part by a shut-off diaphragm extends between the housing assembly and the actuator sleeve. A fluid port is arranged to supply pressurized fluid to the pressure chamber to thereby produce linear movement of the actuator sleeve and the tubular plunger body independent of the pressure at said outlet end, moving the tubular plunger body into engagement with the valve seat to shut off the flow path.

摘要： An irrigation drip tape includes a flexible tube having an interior surface defining a primary flow path. A plurality of secondary flow paths are provided on the interior surface of the tube, the secondary flow paths in substantially axially aligned relationship along a length dimension of the tube. Each of the secondary flow paths are provided with an inlet region, a turbulence-inducing region, a pressure compensation region, and an outlet region having one or more outlets. The outlet region includes a chamber having side walls and upper and lower surfaces with one or more raised surfaces between the upper and lower surfaces to prevent the upper and lower surfaces from engaging and shutting off flow to the one or more outlets as a result of pressure in the primary flow path. The outlet region also includes at least one outlet slit in the tube in communication with the outlet chamber.

摘要： A sprinkler head includes a base; an elongated stem having an inlet supported within the base; a nozzle and a stream deflector supported within the stem, the nozzle and stream deflector cooperating to define an arcuate orifice; a water distribution plate supported on one end of a shaft extending upwardly from the base, the water distribution plate located in axially spaced relationship to the nozzle and adapted to be impinged by a stream emitted from the nozzle. An externally threaded sleeve is fixed to an opposite end of the shaft; and an elastomeric throttle control member constructed with a smooth through-bore is engaged over the externally threaded sleeve to self-tap along the previously smooth bore. The throttle member is prevented from rotating such that rotation of the shaft causes the throttle control member to move axially relative to a flow restriction portion in the inlet, to thereby adjust flow rate through the stem and the nozzle.

摘要： A sprinkler head includes a base having a lower and adapted for attachment to a sprinkler system component; an elongated steam supported within the base; a nozzle and a fixed deflector supported within the stem, the nozzle and deflector cooperating to define an adjustable arcuate orifice. A water distribution plate is supported on a shaft extending upwardly from the stem and has a plurality of water distribution grooves located in axially spaced relationship to the nozzle. An arc adjustment ring is rotatably mounted on the base and is operatively connectable with the nozzle for rotating the nozzle relative to the stem for adjustment of the arcuate discharge orifice. A throttle member is secured to the upstream end of the shaft such that rotation of the shaft causes the throttle to move relative to a portion of the stem, to thereby adjust flow rate through the nozzle.
