摘要： A control loop of a control valve is operated using outlet pressure from a pneumatic amplifier as the control parameter. The control loop may be operated continuously in pressure control mode, or may be switchedd from another mode, such as travel control mode, to pressure control mode in response to certain operating conditions such as operation in the cutoff range, operation with the throttling element engaging a travel stop, or as a backup in the event of primary control parameter sensor failure. Operating the control loop in pressure control mode further allows diagnostics to be performed on the control loop components, even when the system is operating in cutoff range or has engaged a travel stop. The diagnostics may be performed using pressure and displacement sensors normally provided with a positioner. A processor may be programmed to receive data from the sensors and generate fault signals according to a logic sub-routine. The logic sub-routine may include calculating mass flow of control fluid through pneumatic amplifier outlet ports and comparing other operating parameters to detect leaks and blockages in the control loop components. Once a fault is detected, the location of the root cause of the fault may be identified by characterizing operating parameters of the control loop at the time of the fault.

摘要： The present invention describes, generally, a method and system for controlling the dynamics of an actuatable load functioning or operable within a servo or servo-type system, wherein the dynamics of the load are controlled by way of a unique pressure control valve 10 configured to provide intrinsic pressure regulation. The pressure control valve 10, which may be referred to as a dynamic pressure regulator because of its capabilities, utilizes dual spools 40 and 50 that are physically independent of one another and freely supported in the valve body 12 to regulate the pressures acting within the overall system between the control or pilot pressure and the load or load pressure. The dual spools 40 and 50 of the pressure control valve 10, although physically independent of one another, function in cooperation with one another in an attempt to maintain a state of equilibrium in the system, namely to keep pressure acting on or within the actuator 220 (the load pressure), or the feedback force corresponding to the load pressure, the same as the control or pilot pressure. Moreover, pressure regulation and control is intrinsic to the pressure control valve 10 because of the configuration and function of the dual spools 49 and 50 and the mechanical feedback system acting on the spools 40 and 50, thus eliminating the need for electronically or mechanically user controlled systems.
