请参阅图1-5，本发明提供一种技术方案：一种排水管线用平衡轴双向阀板的耐正负压密封装置，包括主体1、压力传导体4和平衡轴双向动力阀板9，所述主体1构包括压力传导腔2和排水腔3，所述压力传导腔2位于排水腔3一侧，所述压力传导体4设置于主体1的压力传导腔2内，所述压力传导腔2上端呈倾斜斜面结构，所述压力传导腔2上端开设有开口，所述开口上端面设有压力传导膜7，所述压力传导膜7下端与压力传导体4上壁面相接触，所述压力传导体4下端固定安装有传动连接杆5，所述压力传导腔2下壁面固定安装有限位底盖8，所述传动连接杆5贯穿于限位底盖8，所述传动连接杆5下端呈圆弧面结构，所述限位底盖8下壁面固定安装有一对平衡支架12，所述平衡轴双向动力阀板9转动连接于一对所述平衡支架12之间，所述平衡轴双向动力阀板9左端上壁面固定安装有支撑杆10，所述支撑杆10上端呈圆弧面结构，所述传动连接杆5下端与支撑杆10上端相接触，所述平衡轴双向动力阀板9右端固定安装有启闭阀板14，所述启闭阀板14与排水腔3下端端口相接触，一对所述平衡支架12之间且位于平衡轴双向动力阀板9上方固定安装有磁芯支架13，所述磁芯支架13上以及平衡轴双向动力阀板9上设有磁芯动力源，所述磁芯动力源包括第一定磁芯16、第二定磁芯17、第一动磁芯18以及第二动磁芯19，所述第一定磁芯16以及第二定磁芯17由左至右依次固定安装于磁芯支架上，所述第一动磁芯18以及第二动磁芯19由左至右依次固定安装于平衡轴双向动力阀板9上，所述压力传导体4、压力传导膜7以及限位盖板之间相互平行，所述压力传导体4下壁面且位于传动连接杆5一侧固定安装有限位板，所述限位板位于压力传导腔2内，所述平衡轴双向动力阀板9前后壁面分别固定安装有转轴11，所述平衡轴双向动力阀板9通过转轴11转动连接于一对所述平衡支架12之间，所述限位底盖8下壁面且位于传动连接杆5一侧开设有气压传导孔6,所述排水腔3下端端口固定安装有密封环15。
其详细连接手段，为本领域公知技术，下述主要介绍工作原理以及过程，具体工作如下。
实施例：根据说明书附图可知，在使用时，当下水管线内出现负压时，压力传感膜7(压力传感膜7采用高弹橡胶材料)上下两端存在压强差，压力传感膜7上端压强大于下端压强，由压强差产生的压力作用于压力传导体4上，压力传导体4产生向下压力，进而使得传动连接杆5下端作用于平衡轴双向动力阀板的支撑杆10上端，由于传动连接杆5下端圆弧面与支撑杆10上端圆弧面接触，通过平衡轴双向动力阀板9的转轴11产生防止启闭阀板15打开的阻力矩，而平衡轴双向动力阀板9的启闭阀板15在下水管线负压作用时，其上下两端也存在压强差，上端压强大于下端压强，因此产生向下压力，也有使启闭阀板15打开的转矩，当启闭阀板15关闭的阻力矩大于等于其打开的转矩时，平衡轴双向动力阀板保持关闭状态，并使启闭阀板15紧压在主体1的密封环16上，第二定磁芯17与第二动磁芯19相吸引，阻止负压通过，可以阻止下水管线内负压作用而产生的水封破坏，而下水管线产生正压或有污水返溢时，平衡轴双向动力阀板9的启闭阀板15的下端受压力作用处于关闭状态(为逆止阀原理)，当排水时，作用于压力传感膜7上的水压小于启闭阀板15的水压，因此产生的阻止启闭 阀板15打开的力矩小于启闭阀板15开启的力矩，平衡轴双向动力阀板打开排水，当排水停止时，平衡轴双向动力阀板9在第二定磁芯17、第二动磁芯19相吸引、第一定磁芯与第一动磁芯相排斥作用下产生使启闭阀板15关闭的力矩，启闭阀板15关闭，阻隔下水管线内的水封和使用空间。
