Abstract:
Diaphragm interface apparatus to improve a cycle life of a diaphragm are described. An example fluid regulator includes a fluid flow passageway between an inlet and an outlet, where a sensing chamber defines a portion of the fluid flow passageway. A diaphragm senses a pressure in the sensing chamber and a diaphragm interface adjacent the sensing chamber has a curved surface to contact a portion of the diaphragm that moves in response to pressure changes in the sensing chamber. The curved surface affects an amount of stress imparted to the portion of the diaphragm during operation of the fluid regulator.
Abstract:
An example loading regulator having an internal relief valve apparatus includes a body having a loading diaphragm disposed between a first casing and a second casing. The first casing and a first side of the loading diaphragm define a first chamber and the second casing and a second side of the loading diaphragm define a second chamber. A relief valve assembly is coupled to the loading diaphragm. The relief valve assembly includes a relief valve seat having an aperture that forms a passageway to fluidly couple the first chamber and the second chamber and a relief valve plug movably coupled to the relief valve seat. The relief valve plug is to move away from the relief valve seat to a bleed position to allow the flow of fluid between the first chamber and the second chamber in response to an outlet pressure substantially greater than a pressure at which the loading regulator enters a lock-up condition.
Abstract:
Temperature-controlled pressure regulators are described. An example temperature-controlled pressure regulator described herein includes a regulator body having a process fluid inlet fluidly coupled to a process fluid outlet via a first passageway and a heat transfer medium inlet to be fluidly coupled to a heat transfer medium outlet via a second passageway, where the heat transfer medium inlet is integrally formed with the regulator body. A heat chamber body is removably coupled to the regulator body to form a chamber between the heat transfer medium inlet and the heat transfer medium outlet. At least a portion of the first passageway is disposed within the chamber, and the chamber is to receive a heat transfer medium via the heat transfer medium inlet to provide heat to the process fluid as the process fluid flows through the chamber via the first passageway, which separates the process fluid from the heat transfer medium.
Abstract:
A pressure regulator comprising a body portion having an inlet port, an outlet port, and a flow passage positioned therebetween is provided. A valve member and a valve seat are positioned in the flow passage. A spring is coupled to the valve member to urge the valve member along an axis towards the valve seat, wherein the flow passage is substantially closed when the valve member engages with the valve seat. The spring has an extended segment in contact with a fixed surface, whereby the extended segment restricts displacement of the spring in a direction substantially perpendicular to the axis.
Abstract:
A control valve system is disclosed which provides a mechanism by which the valve can be moved to its fail-safe position. The system includes a valve actuator (28) which receives pressurized fluid from a regulator (42). The regulator is provided with a reverse pressure exhaust valve (76) such that if pressure within the valve actuator is to be alleviated, as when the valve is to be positioned into its fail-safe position, the reverse pressure exhaust valve (76) is opened thereby providing an immediate and accurate passageway through which excess pressure within the regulator outlet can be alleviated.
Abstract:
A poultry drinker system (10) includes a number of drinker lines (12) each supplied from a common high pressure water supply (16) through a water pressure regulator (20). Each regulator (20) includes a reference spring (76) establishing a default minimum water pressure. A centralized remote control system (26) provides regulated low pressure air (36) to the water pressure regulators (20) to augment the reference spring force and remotely adjust the water pressure in the drinker lines (12). The remote control system (26) periodically applies higher pressure (34) to the water pressure regulators (20) to increase water pressure and flow rates and sequentially flush the drinker lines (12). The remote control system (26) includes a source of high pressure air (34), an air pressure regulator for supplying lower pressure air (38) and a stack of 3-way valves (32) for applying low or high pressure air to each water pressure regulator (20).
Abstract:
The present inventive concept relates to a pilot valve arrangement comprising: a first pilot valve part and a second pilot valve part. The second pilot valve part comprising: a second pilot valve body comprising: a compartment, a low pressure fluid inlet for receiving fluid from the first pilot valve part, and a high pressure fluid inlet, and a fluid outlet for receiving fluid from the low pressure and high pressure inlets via said compartment and providing fluid to a piloted valve. In a first state, the second pilot valve of the pilot valve arrangement provides for a first fluid flow path within the compartment to enable the low pressure fluid inlet to be in fluid communication with the fluid outlet via the first fluid flow path. In a second state, a second fluid flow path within the compartment to enable the high pressure fluid inlet to be in fluid communication with the fluid outlet via the second fluid flow path. The second fluid flow path being different from the first fluid flow path.
