摘要： This disclosure relates generally to valves, and more particularly, to gas valve assemblies. In one illustrative but non-limiting example, a valve assembly may include a valve body, a valve situated in a fluid path of the valve body, a valve actuator for selectively moving the valve actuator, one or more sensors in communication with the fluid path, a controller secured relative to the valve body and in communication with the sensors, and memory operatively coupled to the controller. A user interface may be in communication with the memory and the controller and may be configured to receive a selection from a user for selecting one of two or more selectable options from the memory. The controller may compare sensed parameters to threshold values associated with the selected option. The user interface may have a lock on it to prevent tampering and to provide accountability.

摘要： An electrically-controlled water pressure regulator for use with a poultry watering system receives potable water at a first high pressure level and reduces the water pressure level of the water provided to watering valves that dispense water to the flock within a poultry house. A variable control valve uses a needle-shaped cone to engage a round port inside the housing of the regulator. A stepper motor controls the liner movement of the control valve in incremental microsteps to adjust the water pressure level provided to the flock. A feedback component enables the variable control valve to maintain the water pressure level at a desired set point for the flock. The desired set point for the flock is controlled or automated to match the growth of the flock over their growth cycle. An electrical controller and suitable cabling enable multiple regulators to be controlled efficiently and cost-effectively.

摘要： In a method for setting a command-response characteristic of an oil pressure control apparatus for each oil temperature, the command-response characteristic actually measured at a reference oil temperature is treated as a reference I-P characteristic. Then, a stroke-response characteristic is calculated based on the reference I-P characteristic, a thrust-force correlation and a restoring-force correlation. An overlapping length and a clearance width of overlapping areas between a sleeve and a spool of the oil pressure control apparatus are estimated based on the reference I-P characteristic and the stroke-response characteristic. Finally, the command-response characteristics for each oil temperature are decided and set based on the overlapping length and the clearance width.

摘要： A fluid-pressure regulator for regulating the pressure of a fluid. The regulator includes a variable-resistance fluid element and a variable-volume fluid element located downstream of the variable-resistance element. Pressure in the fluid at the outlet of the regulator is controlled by substantially simultaneously changing the resistance of the variable-resistance element and the volume of the variable-volume element. In one example, a decrease in pressure is effected at the outlet by simultaneously increasing the resistance of the variable-resistance element and increasing the volume of the variable-volume element. Some embodiments of the regulator are particularly useful to effect long-term and high-speed pressure changes in high-resistance fluidic channel networks.

摘要： A system and method of monitoring and controlling the open and close states of a manifold diaphragm type valve includes using an actuator mechanism with feedback control. A pressure transducer and/or force gauge located on the contact end of the actuator mechanism monitors the pressure and/or force applied to the end of the actuator mechanism. A controller instructs the actuator mechanism to move forward or backward an appropriate distance based on the monitored pressure and/or force. Temperature and pressure changes in the system and material changes to the diaphragm are sensed immediately and positioning correction is applied to the actuator in real-time, thereby maintaining the same valve state while monitoring pressure separately. The linear actuator functions as a ‘smart’ actuator, capable of fine tune adjustments without additional outside monitoring and providing a more accurate and reliable method of closing the valve in a dynamic environment.

摘要： A pilot valve (2) for controlling operation of a hydraulically-actuated pressure reducing valve, the pilot valve including a housing (4), and a first valve member (15) mounted in the housing for longitudinal movement along an axis relative to the housing and to a second valve member (22) in response to the outlet pressure of the pressure reducing valve. The first valve member is provided with an aperture (20) and the second valve member comprises a closure portion which varies the effective flow cross section of the aperture in accordance with relative longitudinal movement between the first and second valve members. An adjuster (26) controls the relative rotational position of the first and second valve members, the closure portion having a profile such that relative rotation between the first and second valve members causes the closure portion to vary the effective flow cross section of the aperture (20).
