如图1-11所示，这个例子解决了使得阀芯201稳定地压在两个密封圈102上的问题，
一种稳定密封球阀，还包括设置在转柱606上的螺旋槽605，以及设置在阀盖501中部的凸圆柱502，凸圆柱502的内端插在螺旋槽605上。阀杆601顺时针转动时带动转柱606顺时针转动，转柱606顺时针转动时带动其上的螺旋槽605在凸圆柱502上滑动，随着转柱606顺时针转动的同时，转柱606还会向下移动，进而驱动连接杆604和滑块603向下移动，进而当阀芯201达到关闭位置时，滑块603会下压凸台202和阀芯201，使得阀芯201始终受到下压的力，进而使得阀芯201稳定地压在两个密封圈102上，提升了阀门的密封性。
如图1-11所示，这个例子解决了避免阀盖501的上部泄露液体的问题，
所述稳定密封球阀还包括压盖504、密封填料505和手杆602，阀盖501的上部设置有密封填料505，阀盖501的上端连接有压盖504，手杆602固定连接在阀杆601的上端。密封填料505可以对阀盖501的上侧进行密封，避免阀盖501的上部泄露液体，阀杆601穿过密封填料505，密封填料505也在阀杆601和阀盖501之间起到了密封作用，通过手杆602便于扳动阀杆601转动。
