    • A flow control valve and a valve-position monitoring and control system coupled to the valve member and configured to precisely determine valve conditions related to the rotary position of the valve member. The system has an array of spaced apart transducers in an arcuate arrangement and in a fixed, non-moveable position relative to the valve's housing. A magnetic-field source is fixed to and rotates with the valve member as a unit. The magnetic-field source includes magnetic members adjacent to and out of physical engagement with the transducers. The magnetic member moves along an arcuate path parallel to the arcuate arrangement of the transducers as the valve member rotates through the plurality of rotary positions. The magnetic-field source provides magnetic flux detectable by at least a plurality of the transducers to precisely determine the rotational position of the magnetic-field source and/or the valve member, and the fluid flow rate through the control valve.
    • 流量控制阀和阀位置监视和控制系统,其耦合到阀构件并且构造成精确地确定与阀构件的旋转位置相关的阀状态。 该系统具有弓形布置的间隔开的换能器阵列,并且相对于阀的壳体处于固定的不可移动位置。 磁场源固定到阀构件并以其旋转。 磁场源包括与换能器相邻和离开物理接合的磁性构件。 当阀构件旋转通过多个旋转位置时,磁性构件沿着平行于换能器的弓形布置的弓形路径移动。 磁场源提供由至少多个换能器可检测的磁通量,以精确地确定磁场源和/或阀构件的旋转位置以及通过控制阀的流体流速。

    • A valve is provided for controlling flow along a fluid line that includes an outer shell and an inner housing slidably disposed therein that includes connector threads surrounding a boss on one end and a passage through the boss. A backing member is coupled to the outer shell and has a sealing pin extending into the passage. The inner housing is movable helically relative to the outer shell from a closed position wherein a sealing pin engages an outlet opening at the distal end of the boss to seal the opening and an open position in which the inner housing is directed away from the sealing pin to open a fluid path through the valve. A torque limiter mechanism between the outer shell and inner housing resists movement from the valve closed position to the valve open position until a selected torque level is reached.
    • 提供了一种用于控制沿着流体管线的流动的阀,该流体管线包括外壳和可滑动地设置在其中的内部壳体,其包括围绕一端的凸台和穿过凸台的通道的连接螺纹。 背衬构件联接到外壳并且具有延伸到通道中的密封销。 内部壳体相对于外壳从闭合位置螺旋地移动,其中密封销与凸起的远端处的出口开口接合以密封开口和打开位置,在该位置内部壳体远离密封销 打开通过阀门的流体路径。 外壳和内壳之间的扭矩限制器机构抵抗从阀关闭位置到阀打开位置的运动,直到达到选定的扭矩水平。
