发明内容
针对上述现有技术的不足之处，本发明解决的问题为：提供一种操作便利、具有多重密封结构的连动密封式风阀。
为解决上述问题，本发明采取的技术方案如下：

进一步，所述密封环的内侧密封凸环和锥形密封环面之间设有扩容式凹环槽；所述扩容式凹环槽呈内端大、外端小的圆锥形结构。
进一步，所述密封环的内侧密封凸环的四周内侧边缘设有内侧大、外侧小的扩容式锥形环面。
进一步，所述转动杆的外端设有插接槽；所述插接槽上穿接有锁定杆；所述锁定杆呈工字型结构；所述锁定杆水平分布并且锁定杆两侧抵接于转动杆的外端两侧；所述滑动伸缩杆的内端插接于转动杆外端的插接槽内；所述滑动伸缩杆的内端转动穿接在锁定杆的中间。
进一步，所述外端封闭板的内侧面上设有呈水平方向分布的长条形滑槽；所述滑动伸缩杆的外端设有卡接齿；所述滑动伸缩杆通过外端的卡接齿水平滑动卡接于外端封闭板内侧面上的长条形滑槽内。
进一步，所述阀体的内端四周内侧设有环形安装槽；所述阀体的外端四周设有抵接环体；所述密封环的内端四周外侧设有连接环体；所述密封环通过内端四周外侧的连接环体连接于阀体内端四周的环形安装槽内；所述密封环的外端环面抵接安装于阀体外端四周的抵接环体内侧。
进一步，所述阀体内部设有内侧大外侧小的锥形贴合环面；所述密封环中间四周外侧设有内侧大外侧小的锥形抵接环面；所述密封环通过中间四周外侧的锥形抵接环面与阀体内部的锥形贴合环面贴合密封连接。
本发明的有益效果
本发明旋转驱动杆，驱动杆带动内端封闭板转动，使得内端封闭板四周分离于内侧密封凸环四周内侧，同时内端封闭板带动转动杆转动，当转动杆转动时带动滑动伸缩杆的外端滑动卡接于外端封闭板的内侧面上，同时转动杆会拉动滑动伸缩杆向内端移动，如此使得滑动伸缩杆拉动外端封闭板沿着导向柱和导向筒的导向方位向内端移动，从而使得外端封闭板的四周外侧脱离锥形密封环面，如此通过驱动杆的转动实现了内端封闭板的旋转分离和外端封闭板的平移分离，实现了双重分离；当逆向旋转驱动杆时，使得内端封闭板四周密封抵接于内侧密封凸环四周内侧，同时内端封闭板带动转动杆转动，当转动杆转动时带动滑动伸缩杆的外端滑动卡接于外端封闭板的内侧面上，同时转动杆会推动滑动伸缩杆向外端移动，如此使得滑动伸缩杆推动外端封闭板沿着导向柱和导向筒的导向方位向外端移动，从而使得外端封闭板的四周外侧密封抵接于锥形密封环面的四周内侧，如此通过驱动杆的转动实现了内端封闭板的旋转密封抵接和外端封闭板的平移密封抵接，如此实现了双重密封效果；综上，本发明通过驱动杆的转动实现了内端封闭板的旋转式分离或抵接于内侧密封凸环，同时实现了外端封闭板平移式的分离或抵接于锥形密封环面，如此实现了同步的双重分离或密封连接效果。
