    Abstract: A ball valve having reduced torque requirements for rotation is presented. Torque reduction is realized by providing a shaped sealing back member to provide a back force behind essentially the entire sealing surface of the downstream seal. Torque reduction is also realized by providing a dynamic sealing configuration that varies the sealing force over the valve's operating pressure conditions. An initial bias sealing force is applied by a spring member which also provides a low uniform as-assembled valve torque. As fluid pressure increases, the sealing pressure also increases as an o-ring is forced along a ramped surface of the seal. As inlet pressure decreases, the o-ring is allowed to back down the ramped surface to reduce the sealing force against the valve member. This sealing configuration allows for reverse flow or improper installation of the ball valve, and bottoms out to maintain a sealing force at higher back pressure conditions.

    Abstract translation: 提出了一种具有降低的旋转要求的球阀。 通过提供成形的密封背部构件来实现扭矩减小,以在下游密封件的基本上整个密封表面之后提供背力。 扭矩减小也通过提供动态密封结构来实现,该结构改变阀门操作压力条件下的密封力。 初始偏置密封力由弹簧构件施加,该弹簧构件还提供低的均匀的组装的阀门扭矩。 随着流体压力的增加,密封压力也随着O形环沿着密封件的倾斜表面被推动而增加。 随着入口压力的降低,允许O形圈退回斜面以减小对阀件的密封力。 该密封结构允许反向流动或不正确地安装球阀,并且在较高的背压条件下底部保持密封力。
