摘要： A flapper type downhole valve is opened by flow against the flapper. The flapper and the housing contain magnets that hold the flapper open after it has been opened by flow to keep the flapper from chattering from the flow going past it. The strength of the force is not sufficient to hold the flapper open against a torsion spring on a pivot pin, when there is no flow through the valve. The valve can still be held in the locked open position with no flow through the housing by pressurizing the surrounding annulus to position another magnet to increase the holding force to a level greater than the force of the torsion spring. The additional magnet is spring biased so that upon removal of annulus pressure it shifts to allow the flapper to close. Alternative designs with and without a flow tube are possible. Fixed or movable restrictions can be associated with the flow tube to create a force to shift it to open a flapper with flow into the well.
摘要翻译：挡板式井下阀门通过流动挡板打开。挡板和壳体包含磁体，它在通过流动打开后将挡板保持打开状态，以防止挡板从流过其的流动颤动。当没有流过阀门时，力的强度不足以将挡板保持在枢轴销上的扭转弹簧上。阀仍然可以保持在锁定的打开位置，没有流过壳体，通过对周围的环进行加压来定位另一个磁体，以将保持力增加到大于扭簧的力的水平。额外的磁体是弹簧偏置的，因此在移除环形压力时，它移动以允许挡板关闭。具有和不具有流管的替代设计是可能的。固定的或可移动的限制可以与流管相关联以产生力以使其移动以打开具有流入井的挡板。

摘要： The position of a movable downhole component such as a sleeve in a choke valve is monitored and determined using an array of sensors, preferably Hall Effect sensors that measure the strength of a magnetic field from a magnet that travels with the sleeve. The sensors measure the field strength and output a voltage related to the strength of the field that is detected. A plurality of sensors, with readings, transmits signals to a microprocessor to compute the magnet position directly. The sensors are in the tool body and are not mechanically coupled to the sleeve. The longitudinal position of the sleeve is directly computed using less than all available sensors to facilitate the speed of transmission of data and computation of actual position using known mathematical techniques.
