Embodiment Construction

[0031] While a detailed description of many different embodiments of the invention is presented below, it should be understood that the legal scope of protection of the invention is defined by the words of the claims that issue at the end of this patent application. The detailed description is to be construed by way of example only and does not describe every possible implementation of the invention since describing every possible implementation would be impractical, if not impossible. Numerous alternative embodiments could be implemented, using either current technology or technology invented after the filing of this patent, which would still fall within the scope of the claims defining the invention.

[0032] It should also be understood that unless a term is expressly defined in this patent using "the term '______' as used herein is intended to limit the meaning of the term by implication, or to go beyond the ordinary or ordinary meaning of the term, and such terms should n...

Abstract

The invention relates to a fluid adjustment device, which comprises a valve actuator shell, a control component and an offset structural member, wherein the valve actuator shell defines a control cavity and a valve actuator opening; the control component is arranged in the control cavity and comprises a piston, a valve rod, a lever and a control element; the lever is coupled between the piston and the valve rod; the control element is arranged on the valve rod opposite to the lever; the valve rod penetrates through the valve actuator opening, so that the control element is arranged outside the control cavity; the valve rod has a response to the sliding displacement of the piston and can slide relative to the valve actuator opening; at least partial offset structural member is supported in the valve actuator opening; and the control element and the valve rod are offset towards the control cavity.

Description

technical field [0001] The present disclosure relates to gas regulating devices, and more particularly, to trim components for gas regulating devices. Background technique [0002] Typically the pressure of the gas supplied by the gas distribution system can vary depending on the requirements of the system, climate, supply source and / or other factors. However, most end-user facilities equipped with gas appliances such as stoves, stoves, etc. require the gas to be delivered at a predetermined pressure, and at or below the maximum capacity of the gas conditioning device. Accordingly, gas conditioning devices are implemented to these distribution systems to ensure that the gas being delivered meets the requirements of the end user facility. Conventional gas regulating devices generally include closed-loop control valve actuators for sensing and controlling the pressure of delivered gas. [0003] figure 1 A conventional gas regulating device 10 is described. The regulating d...
