Problems solved by technology

This is undesirable as it is labor intensive (especially with large size shafts) and hammering the collet or end of the valve shaft has the potential to cause internal damage to the valve assembly

Embodiment Construction

[0023] figure 1 An example valve assembly 100 is depicted. The example valve assembly 100 may be used in a process control system to control, for example, temperature, pressure, or flow rate. The example valve assembly 100 can be used to open a fluid path, close a fluid path, and / or change the size of an opening in a fluid path (ie, throttle). For example, as fluid flows through a fluid path including example valve assembly 100 , changing the size of the opening in example valve assembly 100 causes the flow rate of fluid in the fluid path to decrease or increase depending on how open or closed valve assembly 100 is.

[0024] Such as figure 1 As shown, the example valve assembly 100 includes a valve 102 , an actuator 104 and a lever 106 . The joystick 106 is mechanically connected to the actuator 104, as incorporated below Figure 2B to Figure 3B mentioned. The actuator 104 is configured to actuate (ie, rotate, turn, etc.) the lever 106 relative to the axis of the lever to...

Abstract

Actuator levers, collets and collet tools for use in process control devices are disclosed.. An example apparatus includes an actuator lever (106), a collet (202) coupled to the actuator lever, and a collet tool (402). In the example apparatus, the collet tool is removably coupled to at least one of the lever or the collet, and the collet tool applies a force to at least one of the actuator lever, the collet, a valve shaft, or an intervening structure to couple or decouple the collet to or from the lever.

Description

technical field [0001] The present disclosure relates generally to process control equipment, and more particularly, to actuator levers, collets, and collet removers for process control equipment. Background technique [0002] Fluid process systems typically use valves, such as rotary valves, to control temperature, pressure, and other parameters associated with the fluid control process. A rotary valve typically has a stem or shaft that is mechanically connected to an actuator. In operation, an actuator may rotate a valve shaft to move a control member (eg, a disc) between an open position that allows fluid to pass through the valve and a closed position that substantially prevents fluid from passing through the valve. Rotary valves are typically installed in pipeline lines so that when a control element (eg, disc) is moved (ie, opened / closed), the flow of fluid through the valve and thus through the pipeline can be varied (eg, in throttling control operation or on / off op...
