AI Technical Summary

Problems solved by technology

However, for many applications, such as those involving bellows mentioned above, only limited access allowances are provided for the connection point of the actuator rod to the extension rod.
As a result, it is often difficult to access the means for locking (i.e., preventing rotation) the actuator rod relative to the extension rod using the tools used to adjust, secure, or otherwise affect the locking device

Embodiment Construction

[0015] Examples of the anti-rotation means described herein allow an externally threaded assembly to be rotationally locked to an internally threaded assembly without the use of known locknuts, lockwashers, etc. More specifically, the anti-rotation devices described herein may be particularly useful for rotatably locking an externally threaded shaft or rod to an internally threaded component such as another shaft, actuator rod, or the like. In contrast to known anti-rotation devices such as lock nuts and lock washers, the anti-rotation device described herein is disposed within (i.e. surrounded by) the female component and can be configured so that it does not require Tools (eg, wrench, screwdriver, etc.) are generally required to rotatably lock the internally threaded component to the externally threaded component.

[0016] More specifically, as will be described in more detail below, an example of an anti-rotation device includes a first member disposed within an internally ...

Abstract

An example anti-rotation apparatus (100) includes a first member configured to be disposed within an apenure of an internally threaded component (202). The first member includes a first end (102) having a recessed portion (104) configured to receive a second member (200) disposed within the aperture of the internally threaded component (202). The recessed portion (104) of first member is configured to receive the second member (200) to cause a peripheral portion of the first end (102) of the first member to fricticanally engage a surface (214) within the aperture (204) of the internally threaded component (202).

Description

technical field [0001] The present disclosure generally relates to inhibiting or preventing rotation between threaded components and, more particularly, to an internally threaded component such as an actuator stem and an externally threaded component such as a valve stem extension rod, etc. Anti-rotation device that rotates between them. Background technique [0002] Process control plants often employ sliding stem type valves to control the flow of process fluids. Sliding stem valves typically include a stem that extends from the body of the valve and is connected to an actuator by a stem connector. Typically, an actuator (e.g., pneumatic actuator, electric actuator, hydraulic actuator, etc.) drives the valve stem (e.g., by causing the valve stem to move toward / away from the valve body) in response to the controller, thereby changing the The flow rate of fluid flowing through the valve. [0003] In some cases, such as applications involving high temperature environments ...
