具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图1-5，本发明提供一种技术方案：一种双向密封蝶阀的驱动装置，包括阀体、位于阀体内的蝶板17和控制蝶板17转动的旋转装置，控制蝶板17旋转的旋转装置包括手轮1、行星齿轮减速装置2和设置在箱体15内的对开卡环3、传动丝杆5、与传动丝杆5相适配的铜螺母6和花键摆板10，所述的手轮1通过行星齿轮减速装置2与传动丝杆5连接，传动丝杆5前、后端套接对开卡环3，对开卡环3外部设有前挡套4和后挡套14，前挡套4和后挡套14与箱体15内壁连接；所述传动丝杆5的螺纹部连接铜螺母6，铜螺母6通过螺母连接板轴用挡圈7连接螺母花键摆板连接板8的一端，螺母花键摆板连接板8的另一端通过花键摆板轴用挡圈9连接花键摆板10的一端，花键摆板10的另一端连接蝶阀花键上轴11。
图3所示，铜螺母6设有2个通孔，一个与传动丝杆5螺纹连接，另一个套接在铜螺母导向杆12上，与传动丝杆5平行处设有铜螺母导向杆12，铜螺母导向杆12两端通过螺钉固定在阀体内，可防止铜螺母6移动时移位。
图1所示，后挡套14内设有传动丝杆尾套13，传动丝杆尾套13通过尾套螺母16与后挡套14连接。
蝶板17的旋转装置上有一个显示蝶板旋转刻度指示牌。
图1所示，花键上轴11和下轴18与蝶板17连接处是凸轮。
本发明是这样使用的：
开启过程:
手轮1逆时针旋转,通过行星齿轮减速箱装置2减速，带动传动丝杆5旋转，驱动铜螺母6运行，通过铜螺母花键摆板连接板8，带动花键摆板10旋转，花键摆板10驱动蝶阀花键上轴11带动蝶板17旋转，使蝶板17快速开启。开启过程中，铜螺母6反向作用力，传递到传动丝杆5上，通过对开卡环3传递到前挡套4，从而传到箱体16上，使箱体16只受到压力，不受拉力。同时蝶阀花键上轴11、下轴是凸轮机构，蝶板垂直蝶阀花键上轴11、下轴水平移动，开启后蝶板17迅速脱离蝶阀花键上轴11、下轴，蝶板17密封面脱离，磨擦消失。随着上轴、下轴的继续旋转，蝶板17开启到位，处于全开状态。到位后，蝶板16通过蝶阀花键上轴11带动指针旋转，蝶板从刻度指针显示到位后，静止在阀体内，即使纹流状态也不会颤动。
关闭过程:
手轮1顺时针旋转,通过行星齿轮减速箱装置2减速，带动传动丝杆5旋转，驱动铜螺母6运行，通过铜螺母花键摆板连接板8，带动花键摆板10旋转，花键摆板10驱动蝶阀花键上轴11带动蝶板16旋转，使蝶板16快速关闭。关闭过程中，铜螺母6反向作用力，传递到传动丝杆5上，通过传动丝杆尾套13及尾套螺母16，传递到后挡套14，从而传到箱体15上，使箱15只受到压力，不受拉力。同时蝶阀花键上轴11、下轴是凸轮机构，蝶板16垂直蝶阀花键上轴11、下轴水平移动，开启后蝶板16逐渐接触蝶阀花键11上轴、下轴，蝶板密封面压紧，磨擦消失。随着上轴、下轴的继续旋转，蝶板关闭到位，处于关闭状态。到位后，蝶板17通过蝶阀花键上轴11带动指针旋转，蝶板17从刻度指针显示到位后，静止在阀体内，即使纹流状态也不会松动。
尽管已经示出和描述了本发明的实施例，对于本领域的普通技术人员而言，可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行多种变化、修改、替换和变型，本发明的范围由所附权利要求及其等同物限定。
