Drain valve assembly

Methods, apparatus, systems, and articles of manufacture for variable drain valve assemblies are disclosed. An example variable bleed valve assembly includes a variable bleed valve (VBV) gate corresponding to a bleed port and a first coordination ring to which the VBV gate is coupled, the first coordination ring moving in a circumferential direction between a first position and a second position causing the VBV gate to move between the first position and the second position. 公开了用于可变排放阀组件的方法、装置、系统以及制品。示例可变排放阀组件包括对应于排放端口的可变排放阀(VBV)门和第一协调环，VBV门联接到第一协调环，第一协调环在第一位置和第二位置之间沿周向方向移动，使VBV门在第一位置和第二位置之间移动。
