    • It is inevitable for the tight closure of a ball valve to be disturbed by its ball's wedging action, and its ball seat is an upset impulse amplifier with an inherent disturbance resistance index or a sealing maintaining factor m. The ball valve seat designed with equilateral triangle section methods of the invention can positively ensure itself a resistance to ball-wedged disturbance from eccentric drive to make a ball valve realize its tight closure by the floated pressure of balls or seats onto each other and ensure that the ultimate rotational resistance to the ball only relates to the ultimate pressure from/on one seat. Because the seat of the prior art can not ensure balls or seats against each other a floated pressure sufficient to resist to the ball-wedged disturbance from eccentric drive, the tight closure of the ball valve has to be realized by either larger preclamping force or larger spring preload between seats and balls so as for the ultimate rotational resistance to balls to be from larger ball-clamping forces from two seats. Therefore, the ball valve in accordance with the invention is a real floating or mounted ball valve, whose operation torque can be at most half of that of a formal or false floating ball valve of the prior art.
    • 球阀的紧密封闭是不可避免的受到球的楔入动作的干扰,球座是具有固有的抗干扰指数或密封保持因子m的镦锻脉冲放大器。 本发明的等边三角形截面方法设计的球阀座可以确保自身抵抗偏心驱动的球形扰动,使球阀通过球或座的浮动压力实现其紧密关闭,并确保 对球的极限旋转阻力仅与一个座椅上的最大压力有关。 由于现有技术的座椅不能确保球或座彼此具有足以抵抗来自偏心驱动的球楔扰动的浮动压力,所以球阀的紧闭必须通过较大的预夹紧力或较大的 在座椅和球之间的弹簧预加载,以便对球的极限旋转阻力来自两个座椅的较大的球夹紧力。 因此,根据本发明的球阀是真正的浮动或安装的球阀,其操作扭矩可以是现有技术的形式或假浮球阀的最大一半。

    • A stem shoulder seal with double rings is composed of a sealing ring, a clamping ring and a spherical or conical stem shoulder, and the sealing ring is of a self-energized seal designed to its ultimate allowable strength and automatically free of any load beyond its ultimate strength. An assembly of independent dual stem seals, consisting of a stem shoulder seal with double rings, a stem cylinder seal with triangular sections and an isolating mating, can ensure that a stem has three seals which get well seated automatically at the same time to bear an identical ultimate medium pressure independently or without any mutual interference in service when assembled to the extent that the stem operating torque is just definitely increased, thereby ensuring that a stem sealing has a triple safety.
    • 具有双环的杆肩密封件由密封环,夹紧环和球形或圆锥形杆肩组成,密封环具有自给自足的密封,设计为其极限允许强度,并自动消除超过其的任何载荷 极限强度。 独立的双杆密封组件,由带双环的杆肩密封件,具有三角形截面的阀杆气缸密封件和隔离配合件组成,可确保阀杆具有三个密封件,同时自动完全自动承受 相同的最终介质压力在组装时独立地或没有任何相互干扰的作用,使得阀杆操作扭矩肯定地增加,从而确保阀杆密封具有三重安全性。
