Abstract

阀杆(4)连同旋转盘(2)并在“撑拢”轨道(6)强制作用下，带动限位销(3)及阀门密封结构件，按固定盘(1)上的“圆弧连直线”轨道(5)的轨迹顺时针旋转，阀门关闭。反之，逆时针旋转，阀门开启。

Description

盘形双轨道式旋转加撑拢的阀门启闭结构
技术领域：本发明属阀门行业中的阀门启闭结构技术。
背景技术：球阀、蝶阀、旋塞阀如果采用斜面撑开、摆动角度、滚动贴压、旋塞升降的组合球体、组合蝶板、组合旋塞等密封结构；其启闭过程，一般均为旋转加升降的复合运动过程；其启闭结构一般分为四种：旋转和升降分开动作式、螺旋轨道复合动作式、90°直角轨道复合动作式、双轨道复合动作式(筒形)。
发明内容：本发明的目的是提供一种盘形双轨道式旋转加撑拢的阀门复合启闭结构。
适用于球阀、蝶阀、旋塞阀的盘形双轨道式旋转加撑拢的启闭结构主要是由固定盘(不能旋转)、旋转盘和限位销组合而成。其主要特征是：固定盘上带有“圆弧连直线”的轨道；旋转盘上带有“角度”或“弧度”或“角度连弧度”的“撑拢”轨道；限位销直穿于固定盘和旋转盘的轨道中间。其工作原理是：外力驱动阀杆连同旋转盘带动限位销，先按固定盘上的“圆弧”轨道的轨迹顺时针旋转，当限位销旋转到“圆弧”轨道相连的“直线”轨道时，旋转盘继续顺时针旋转，限位销在旋转盘上“撑拢”轨道的强制作用下，按固定盘上的“直线”轨道轨迹向固定盘周边撑开，这时限位销连同阀门密封结构件压向阀座，阀门关闭。当阀杆连同旋转盘逆时针旋转，在旋转盘上“撑拢”轨道的强制作用下，限位销连同阀门的密封结构件先按固定盘上的“直线”轨道的轨迹向固定盘中心收拢，再按固定盘上“圆弧”轨道的轨迹逆时针旋转，阀门开启。盘形双轨道旋转加撑拢的阀门启闭结构，根据需要可在阀门密封结构件上端安装一套，也可在上、下端各安装一套。所述固定盘上的“圆弧连直线”轨道和旋转盘上的“角度”或“弧度”或“角度连弧度”的撑拢轨道一般为顺方向，也可设计成反方向。所述固定盘一般在旋转盘上端，也可设计在旋转盘下端。所述限位销在尺寸许可并必要时可装有滚套，使限位销在旋转盘“撑拢”轨道中的滑动摩擦变为滚动摩擦。
本发明所述的启闭结构与现有的启闭结构相比，虽然使用功能基本相同，但比现有结构简单，高度底，使阀门总重量减轻，成本降低。
附图说明：本发明的具体结构由以下的实施例及附图给出。
附图是依据本发明提出的盘形双轨道式旋转加撑拢的阀门启闭结构中的一种机构示意图。
阀杆4连同旋转盘2带动限位销3按固定盘1上的“圆弧连直线”轨道5的轨迹，先顺时针旋转90°后，旋转盘2继续旋转，在旋转盘2上的“撑拢”轨道6的强制作用下，限位销3连同阀门密封结构件按固定盘1上“直线”轨道的轨迹向固定盘1周边撑开，阀门关闭。反之，阀杆4连同旋转盘2逆时针旋转，限位销3连同阀门密封结构件先按固定盘1上的“圆弧连直线”轨道5的“直线”轨道的轨迹向固定盘1中心收拢后，再按固定盘1上的“圆弧”轨道的轨迹逆时针旋转90°，阀门开启。
具体实施方式：本发明与“滚动球球阀密封结构”技术相结合，可设计出低成本、高参数的球阀。
