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.
摘要翻译： 可变弧喷头或喷嘴可以设置到多个位置以调节喷洒器的弓形跨度。 喷头包括一个电弧调节阀，它具有两个部分，这两个部分螺旋地彼此接合，以限定一个开口，该开口可以在喷洒器的顶部调整到所需的弓形长度。 可以通过按压和旋转偏转器来直接致动阀而不需要手动工具来调节弓形长度。 还提供了一种冲洗方法，包括使偏转器在电弧调节位置和可操作的灌溉位置之间移动。 喷洒头还可以包括可以通过喷洒器的外壁部分的致动或旋转来调节的流量调节阀。 外壁部分的旋转导致流动控制构件轴向移动或远离入口。
