    摘要: A flow rate control valve includes a casing provided with an inlet port and an outlet port through which a fluid, the flow rate of which should be controlled, flows in and out, a diaphragm that partitions a space inside the casing into a flow space in which the fluid flows and a working space in which a working medium is present, and a valve body provided on a portion of the diaphragm that opposes the inlet port. The diaphragm is displaced in accordance with a change in the internal pressure of the working space, and the valve body is accordingly moved. This results in a change in the distance between the valve body and the inlet port, and thus the flow rate of the fluid flowing into the flow space through the inlet port is adjusted. Therefore, the flow rate of the fluid flowing out through the outlet port is variably controlled.

    摘要: A feed-forward flow controller is designed to calculate a target valve position from a target flow. Correction is made for liquid or gas pressure drop across the valve and for the valve flow modulating member geometry. This feed-forward action may also be used to linearize a feed-back flow control loop.

    摘要: The system controls of a pneumatically operated valve using an electrical control signal from a controller. A pilot circuit of the system has multiple piezo valves that are subject to electrical signals from the controller to provide pneumatic output signals to a volume booster circuit of the system. Relatively small volume pneumatic pilot signals from the piezo valves are used to determine the opened or closed state of higher volume valve assemblies of the booster circuit which connect or disconnect the actuator of the valve to be operated with a source of pressurized gas. Both the piezo valves and the booster valve assemblies are subjected to gas at the same operating pressure, but the surface area of pistons in the booster valve assemblies exposed to the piezo valves is substantially larger than the surface area of the pistons exposed to operating pressure such that the pneumatic signals shift the pistons even when pressure is the same on both sides thereof. Both singe-acting and double-acting embodiments are disclosed, as well as alternative versions of booster valve assemblies such as having a primary piston and a secondary piston. The secondary piston permits partial flow while the primary piston permits full flow when actuated.

    摘要: A flow controller having a first and second stages of regulation. The first stage is a pressure regulation stage that maintains the pressure within an intermediate chamber (formed by a series of interconnected passageways and cavities) within a predetermined range above the pressure in an outlet port. The second stage maintains the flow rate within a predetermined range about a target flow rate. Both stages sample the pressure in the outlet port and automatically adjust the flow of fluid to ensure that fluctuations in pressure at the inlet and outlet ports do not affect the flow rate. The flow rate is set and controlled by a user determined setpoint. The pressure is regulated by one or more feedback systems. The feedback systems used may be mechanical or electromechanical based on a particular operating environment.
