摘要： An irrigation valve has a valve body with an inlet passage, an outlet passage, and a valve seat intermediate the inlet passage and the outlet passage. A diaphragm includes a valve seat engaging portion that cooperates with the valve seat to control flow through the valve. The valve seat and the valve seat engaging portion of the diaphragm are offset relative to the inlet passage to improve flow through the valve to reduce pressure and energy loss.

摘要： A variable arc sprinkler head or nozzle may be set to numerous positions to adjust the arcuate span of the sprinkler. The sprinkler head includes an arc adjustment valve having two portions that helically engage each other to define an opening that may be adjusted at the top of the sprinkler to a desired arcuate length. The arcuate length may be adjusted by pressing down and rotating a deflector to directly actuate the valve without the need for a hand tool. A method of irrigation is also provided involving moving the deflector between an arc adjustment position and an operational, irrigation position. The sprinkler head may also include a flow rate adjustment valve that may be adjusted by actuation or rotation of an outer wall portion of the sprinkler. Rotation of the outer wall portion causes a flow control member to move axially to or away from an inlet.

摘要： A spray nozzle and method are provided in which fluid flow through the nozzle is inverted and in which a portion of a nozzle body may be rotatable adjusted to distribute water in a desired arc of coverage. Water first flows upwardly through the nozzle body, into an adjustable arcuate chamber defined by a helical interface in the nozzle body, is inverted, and is redirected downwardly through the nozzle body. Water may flow upwardly through a first set of flow passages and downwardly through a second set of flow passages. Water is directed downwardly against a distribution surface having an uneven surface profile for improved water distribution to terrain near to and distant from the nozzle. The water is directed downwardly against the distribution surface in the nozzle body and outwardly to surrounding terrain. The flow passages may be adapted to provide a matched precipitation rate for nozzles with different throw radiuses.

摘要： A variable arc sprinkler nozzle is provided for distribution of water through nearly any adjustable arcuate span. The nozzle includes one or more arcuate slots formed by the helical engagement of spiral surfaces of a deflector and a nozzle body. A user may rotate a portion of the nozzle body to select the arcuate span of the one or more slots. A matched precipitation rate feature is adjustable to proportion the amount of water directed to the deflector depending on the extent of the arcuate span. Further, edge fins on the deflector and nozzle body channel water flow at the two edges of the distribution arc to increase the throw radius and to provide fairly uniform water distribution at the edges of the arc.

摘要： A nozzle is provided having a primary outlet for distribution of water relatively distant from the nozzle and a secondary outlet for distribution of water relatively close to the nozzle. The nozzle includes a threaded portion for coupling the nozzle to a source of pressurized water. A flow channel to the secondary outlet is formed through the threads to provide an appropriate pressure drop to improve water distribution to terrain relatively close to the nozzle. The flow channel may cut across the threads or may extend in the same direction as the threads. The flow channel may be tortuous or non-tortuous based on the number of directional changes in the flow channel, thereby allowing the tailoring of close-in water distribution characteristics.
摘要翻译： 提供一种喷嘴，其具有用于分配相对远离喷嘴的水的主出口和用于分配相对靠近喷嘴的水的次级出口。 喷嘴包括用于将喷嘴连接到加压水源的螺纹部分。 通过螺纹形成到次级出口的流动通道，以提供适当的压力降，以改善与相对靠近喷嘴的地形的水分配。 流动通道可以跨过螺纹切割，或者可以沿与螺纹相同的方向延伸。 基于流动通道中的方向变化的数量，流动通道可以是曲折的或非曲折的，从而允许调整近水分配特性。
