本标准描述了垂直安装、装配式全孔径铝滑动闸门，设计用于普通供水和废水处理设施中的座头或非座头或两者。闸门主要用于关闭或节流通过矩形或圆形孔口、通道末端或通道开口的水流或废水。它们可以是常规封闭或平底封闭类型，可以向上或向下打开。本标准还描述了手动闸门执行机构以及标准附件。ANSI/AWWA C541和ANSI/AWWA C542中描述了动力驱动机构（包括电动或液压）。本版标准的主要修订内容包括:1。前言（第II.A.节）中增加了一节关于弹性体的氯和氯胺降解。构造函数的定义已从标准中删除。 3.要求进行了广泛更新，以在四个滑动门标准中保持一致，但有实质性差异的除外（第4节）。重新整理和澄清了拉伸、压缩和临界屈曲载荷，以及额定载荷和极限载荷的定义。5.增加了拒收依据一节（第5.3节）。

This standard describes vertically mounted, fabricated aluminum slide gates with full-aperture closure, designed for either seating head or unseating head or both, in ordinary water supply and wastewater service. The gates are primarily used to shut off or throttle water or wastewater flow through a rectangular or round orifice, end of channel, or in-channel opening. They may be of either conventional-closure or flush-bottom-closure type and may be opened upward or downward. This standard also describes manual gate actuator mechanisms together with standard accessories. Power-actuated mechanisms (including electric or hydraulic) are described in ANSI/AWWA C541 and ANSI/AWWA C542.Major revisions made to the standard in this edition include the following:1. A section on chlorine and chloramine degradation of elastomers was added to the foreword (Sec. II.A.).2. The definition of constructor has been removed from the standard.3. Requirements, was extensively updated to read consistently among the four slide gate standards, except for where materially different (Sec. 4).4. Tensile, compressive, and critical buckling loads were readdressed and clarified, along with the definitions for rated and extreme loads.5. A basis for rejection section was added (Sec. 5.3).
