摘要： A drop hose clamp for securing a drop hose in a center pivot irrigation system includes a bottom section positionable over a truss rod or in engagement with a span pipe, and a top section pivotally connected to the bottom section and displaceable between an open position and a closed position. With the top section in the closed position, the bottom section and the top section together define a channel that is configured to receive and secure the drop hose. The drop hose clamp may be secured to the truss rod or the span pipe using a connector positioned through a connector slot.

摘要： A sprinkler and side-loading nozzle insert assembly includes a sprinkler body provided with a flow passage and a nozzle insert seated in a complementary recess in said sprinkler body. The nozzle insert is rotatable to plural operating positions and it includes an elongated, substantially cylindrical insert body having an insert axis about which the nozzle insert rotates. A nozzle bore extends through the insert body on an axis transverse to the insert axis and alignable with the flow passage in one of the plural operating positions. A forward end face is provided with a turning knob and plural index tabs extending radially from the insert body at circumferentially-spaced locations proximate the forward end face. The index tabs are adapted to engage respective index notches in the sprinkler body as the insert body is rotated to the plural operating positions.

摘要： A sprinkler controller is cooperable with a sprinkler assembly that receives fluid input from a pipe span. The sprinkler controller includes a microcontroller circuit, a motion sensor coupled with the microcontroller circuit, and a valve assembly including a modulator coupled with the microcontroller circuit and a valve coupled with the sprinkler assembly. The valve meters or controls an amount of fluid output from the sprinkler assembly, and the microcontroller circuit is programmed to control the valve assembly based on input from the motion sensor. With a series of sprinkler controllers in a center pivot irrigation system, the drop numbers for each of the sprinkler assemblies can be determined based on input from the motion sensors.

摘要： A flow control device includes a housing with an inlet and an outlet and a flow conduit disposed in the housing. The inlet, the flow conduit, and the outlet define a flow passage. A valve seat is disposed in the housing downstream of the inlet, and a shuttle is movably disposed in the housing and displaceable between a closed position engaging the valve seat to close the flow passage and an open position spaced from the valve seat to open the flow passage. A sealed chamber is defined between the housing and the flow conduit. A port coupled with a source of pressurized fluid communicates with the sealed chamber, where the shuttle is displaceable between the closed position and the open position based on a pressure in the sealed chamber. The threshold water pressure for displacing the flow conduit may be adjustable by modifying the pressure in the sealed chamber.
