摘要： A method and apparatus for measuring stem nut wear in a valve having a threaded valve stem that is positioned to engage the threads of a stem nut. In a preferred embodiment, a tool is mounted on the stem nut, wherein the tool rotates when the stem nut rotates. The tool indicates a measurement of stem nut rotation. An indicator indicates stem movement. The stem nut is rotated and the amount of percent wear is observed. Rotation continues until the stem begins to move. The tool provides a reading when the stem begins to move that indicates an amount of stem nut wear.

摘要： Apparatuses for providing a visual indication outside a blowout preventer (BOP) relative to a position of ram blocks inside the BOP, and methods of adding such apparatuses to existing blowout preventers are provided. An apparatus has an indicator rod, a detectable portion and a sealing assembly. The indicator rod has an end extending outside an end cap of the BOP, and is configured to engage with a tail rod of a ram block of the BOP, and to switch between a first position when the BOP is in a close state, and a second position when the BOP is in an open state. The detectable portion is located outside the end cap and is configured to provide a visual indication relative to a current position of the indicator rod. The sealing assembly is configured to seal a space inside the end cap from an environment in which the BOP operates.

摘要： A blowout preventer for sealing a tubular of a wellbore is provided. The blowout preventer has a housing having a bore therethrough for receiving the tubular, at least one ram slidably positionable in the housing (each of the rams having a ram block for sealing engagement about the tubular), an actuator for selectively driving the ram block (the actuator comprising a piston slidably positionable in a cylinder), and a monitor for detecting the piston therein. The monitor has a visual indicator on an exterior of the cylinder. The visual indicator is operatively coupled to the piston for displaying a position of the piston as the piston travels within the cylinder whereby a position of the ram may be determined.

摘要： A hydraulic actuating device for a sliding stem control valve assembly is mounted between a control valve and an actuator housing. The hydraulic actuating device is connected to one of a control valve stem, an actuator stem, and a stem connector and the hydraulic actuating device moves either the control valve stem, the actuator stem, or the stem connector in response to varying hydraulic pressure within the hydraulic actuating device. The hydraulic actuating device may be used to override an actuator of the sliding stem valve during emergency operations, or to provide a backup actuator in the case of a primary actuator malfunction.
