Description
- The present disclosure relates to gas regulators, and more particularly, to an apparatus and method for retaining a noise attenuation device for use with a pressure regulator.
- The pressure at which typical gas distribution systems supply gas may vary according to the demands placed on the system, the climate, the source of supply, and/or other factors. However, most end-user facilities equipped with gas appliances such as furnaces, ovens, etc., require the gas to be delivered in accordance with a predetermined pressure, and at or below a maximum capacity of a gas regulator. Therefore, gas regulators are implemented into these distribution systems to ensure that the delivered gas meets the requirements of the end-user facilities.
- Some conventional gas regulators include a noise attenuation device or noise suppression system to reduce noise associated with high pressure gases, for example, of the regulator during operation. Various systems and methods for retaining the noise attenuation device during operation of regulator are known. In one example, and as depicted in
FIGS. 1-3 , aconventional apparatus 10 for retaining anoise attenuation device 12 coupled to a fluid regulating device 13 (FIG. 1 ) includes asingle rod 14 disposed within acenter 16 ofnoise attenuation plates 18. Therod 14 supports theplates 18 within abody 20 of thenoise attenuation device 12. Springs (not shown) are typically enclosed within acage 22, such as a cylindrical cage, disposed within thebody 20 near afront portion 24 of thenoise attenuation device 12. The springs redirect the flow of gas or fluid flowing through thecage 22 and theplates 18 to reduce fluid pressure flowing through an outlet 26 (FIG. 1 ) of a regulator and reduce the noise associated with the same. - In various applications, however, in particular those in which high pressure gas is flowing through the
outlet 26 of theregulator 13, the high force of the outlet pressure causes one or both of thecage 22 andplates 18 to bend. This interferes with, if not destroys, the function of thenoise attenuation device 12. More specifically, and in one example, the force of the fluid pressure causes theplates 18 to detach from an inside surface of thebody 20 of thenoise attenuation device 12 and fold over within thebody 20. As a result, the regulator noise is unable to be reduced or suppressed, and thenoise attenuation device 12 fails to function properly. - In accordance with a first exemplary aspect, a fluid regulating device is disclosed. The fluid regulating device includes a valve comprising an inlet, an outlet, and a valve seat disposed between the inlet and the outlet for allowing fluid to flow through the valve. An actuator is coupled to the valve and includes a control assembly having a control element and a diaphragm operably connected to the control element. The control element is disposed within the valve and adapted to be displaced relative to the valve seat for controlling the flow of a fluid between the inlet and the outlet. A noise attenuation assembly is coupled to the outlet and includes a cylindrical body and at least one plate disposed within the cylindrical body, the at least one plate having an outer edge. An apparatus for retaining the noise attenuation assembly includes a plurality of rods coupled to the at least one plate. The plurality of rods includes at least one rod having a first end disposed through the outer edge of the at least one plate.

In addition, and more generally, the plurality of rods may include six rods disposed in each of the front, middle and rear plates around the outer edges of each of the front, middle, and rear plates.
- In some preferred forms, a nut may secure each rod of the plurality of rods to the outer edges of each of the front, middle, and rear plates. In addition, the apparatus for retaining the at least one plate may further include a front support member coupled to a front surface of the front plate and through which the at least one rod of the plurality of rods is disposed and secured.
