Problems solved by technology

[0005] However, the locking assembly 16 is bulky and cumbersome to install due to its three-part (e.g., main body 20, guide pin 22, and screw 24) configuration, e.g. The notch of 16 is aligned with 28
Furthermore, since there are three parts to the locking assembly 16, there is an increased risk of errors in installing each of these parts, which increases the chance of an invalid lock and ultimately damage and / or injury

Embodiment Construction

[0025] In summary, a one-piece or one-piece locking mechanism for a cover of an electro-pneumatic controller for use with a regulator is disclosed. The electro-pneumatic controller includes a base having a body, a top surface, and an aperture formed in the body. The one-piece locking mechanism is disposed within the bore of the base and includes a top surface that is flush with the top surface of the base. A cover is coupled to the base and includes an open end having a rim. The edge contacts a portion of the top surface of the locking mechanism and the top surface of the base. With a single tool such as an Allen wrench (Allen wrench), the locking mechanism is turned upwards in a counterclockwise direction to lock the cover to the base.

[0026] see now figure 2 , the process control system 100 includes an electro-pneumatic controller 110 operatively coupled to a regulator 111 . In particular, outlet port 112 of electro-pneumatic controller 110 is operatively coupled to t...

Abstract

An electro-pneumatic controller for use with a regulator. The electro-pneumatic controller includes a base having a body, a top surface, and a bore formed within the body. A locking mechanism is disposed within the bore of the body of the base, the locking mechanism having a top surface flush with the top surface of the base. A cover is coupled to the base and includes an open end with a rim, the rim contacting the top surface of the base and a portion of the top surface of the locking mechanism. The locking mechanism is rotated via a tool in a counter-clockwise direction after the cover contacts a portion of the top surface of the locking mechanism to lock the cover to the base.

Description

technical field [0001] In general, the present invention relates to controls for process control valves and, more particularly, to cover locks for electro-pneumatic controls. Background technique [0002] Typically, an electro-pneumatic controller (also referred to as an electro-pneumatic regulator) is used to control the pressure of a control fluid used to position a pneumatic control device (eg, a regulator). For example, an electro-pneumatic controller may be used to control the pressure of a control fluid to a pneumatic actuator of a process control valve or regulator to position the process control valve or regulator. The electro-pneumatic controller may include one or more channels for receiving control fluid, and one or more solenoid valves may control the flow of the control fluid through the channels. The one or more solenoid valves may communicate with a microprocessor, which may communicate with one or more sensors external to the electro-pneumatic controller to ...
