    • A fluid system includes a loading arm connected to a swivel joint. A counterbalance mechanism is connected between the loading arm and the swivel joint. An adjustment mechanism adjusts the counterbalance force applied by the counterbalance mechanism to the loading arm. The adjustment mechanism includes a guide plate connected to the swivel joint and includes a guide slot and a straight bore guide. A bracket is movably connected to the guide plate and has one or more apertures and a threaded bore guide. Fasteners extend through the guide slot and the one or more apertures to selectively secure the bracket to the guide plate. A lead screw is disposed at least partially within the straight bore guide and the threaded bore guide. Rotation of the lead screw causes the bracket to move along a length of the lead screw and thereby adjust the counterbalance force.
    • 流体系统包括连接到旋转接头的加载臂。 平衡机构连接在装载臂和旋转接头之间。 调节机构调节由平衡机构施加到装载臂的平衡力。 调节机构包括连接到旋转接头的引导板,并且包括引导槽和直孔引导件。 支架可移动地连接到引导板并且具有一个或多个孔和螺纹孔引导件。 紧固件延伸穿过引导槽和一个或多个孔以选择性地将支架固定到引导板。 导螺杆至少部分地设置在直孔引导件和螺纹孔引导件内。 导螺杆的旋转使支架沿着导螺杆的长度移动,从而调节平衡力。

    • An adjustable sprinkler head positioning assembly is disclosed that includes a first conduit member and a second conduit member that are selectively positionable relative to each other and to a drop line fitting so as to position a sprinkler head at a desired location. The first and second conduit members each have an inlet portion and an outlet portion that are offset relative to each other by a predetermined distance. The sprinkler head is positionable anywhere within a circle having a radius equal to the sum of the offsetting distances between the inlet and outlet portions of each conduit member. Elbow couplings further increase versatility. The elbow couplings may have an inlet positioned at a 45.degree. angle or a 90.degree. angle relative to an outlet.A drop line fitting is weldable to a sprinkler drop line and includes a socket for receiving sprinkler system plumbing such as the first and second conduit members.A drop line fitting is releasably secured to a sprinkler pipeline and includes either a socket for receiving sprinkler system plumbing such as the first conduit member or includes a portion having a smooth outer circumferential surface to be received by a socket of sprinkler system plumbing such as the first conduit member.
    • 公开了一种可调节喷洒头定位组件,其包括第一导管构件和第二导管构件,所述第一导管构件和第二导管构件相对于彼此可选择性地定位并且与下降线配件相关联,以将喷洒头定位在期望位置。 第一和第二导管构件各自具有相对于彼此偏移预定距离的入口部分和出口部分。 洒水头可定位在圆内的任何地方,其半径等于每个管道构件的入口和出口部分之间的抵消距离之和。 弯头联轴器进一步增加了多功能性。 弯头联接器可以具有相对于出口定位成45度角或90度角的入口。 下落线配件可焊接到喷洒器下落管线并且包括用于接收诸如第一和第二管道构件的喷淋系统管道的插座。 液滴管线可拆卸地固定到喷洒管道上,并且包括用于接收诸如第一导管构件的喷洒系统管道的插座,或包括具有光滑外周表面的部分,以由喷洒系统管道的插座(例如 第一管道构件。
