Problems solved by technology

While effective in regulating flow, the subassembly 66 is rather expensive to make
Also, the subassembly 66 requires modifications to the standard regulator valve body and does not facilitate conversion to other body sizes

Embodiment Construction

[0025] While the following text sets forth a detailed description of various embodiments of the invention, it should be understood that the legal scope of the invention is defined by the words of the claims appended hereto. The detailed description should be construed as exemplary only and not describing every possible embodiment of the invention since describing every possible embodiment would be impractical, if not impossible. Various alternative embodiments could be implemented, using either current technology or technology developed after the filing date of this patent, which would still fall within the scope of the claims defining the invention.

[0026] It should also be understood that unless a term is expressly defined in this patent by means of the sentence "As used herein, the term '______' is hereby defined to mean..." or a similar sentence, no intention is to go beyond its simplicity or Ordinary meanings limit the meaning of terms, whether express or implied, and s...

Abstract

A gas regulator includes an actuator, a valve, and a balanced port housing disposed within the valve for flow conditioning to convert turbulent flow within the valve to laminar flow when the fluid reaches the sensing point of a Pitot tube disposed within the outlet of the valve. The balancing port housing includes an opening through a sidewall and disposed between a valve port of the valve and the outlet. The opening may include a partial obstruction, such as baffles or a mesh screen over which the fluid flows to convert the turbulent flow to laminar flow. The regulator may further include balanced trim having a balancing diaphragm in fluid communication with the upstream pressure to apply a force to a valve disc of the valve in the opposite direction of the force applied to the valve disc by the upstream pressure so that the upstream pressure does not affect the regulator's control of the downstream pressure.

Description

field of invention [0001] The present invention relates to gas regulators, and more particularly, to gas regulators having actuators with closed loop control. Background technique [0002] The pressure at the gas supply of a typical gas distribution system will vary depending on demand on the system, climate, supply source and / or other factors. However, most end-user facilities equipped with gas appliances such as furnaces, ovens, etc. require gas to be delivered at a preset pressure and at or below the maximum capacity of the gas regulator. Therefore, gas regulators are provided to these distribution systems to ensure that the gas delivered meets the requirements of the end-user facility. Conventional gas regulators typically include a closed-loop control actuator for sensing and controlling the pressure of the delivered gas. [0003] In addition to closed loop control, some conventional gas regulators include balanced trim to improve the response of the gas regulator to ...
