AUTOMATIC SPEED SEARCHING DEVICE AND METHOD FOR A PARTIAL STROKE TEST OF A CONTROL VALVE. |
摘要 |
<p>An automatic speed searching device for a partial stroke test of a control valve includes a spool valve operatively connected to a pilot valve and a blocker valve. An electrical module is operatively connected to the pilot valve, a supply of control fluid, and the blocker valve. In an open position of the spool valve, a first control fluid inlet is fluidly connected to a first control fluid outlet, and in a closed position of the spool valve the first control fluid outlet is fluidly connected to a second control fluid outlet. A method of determining an optimum stroke speed includes iteratively powering a main and secondary solenoid in the electrical module and updating parameters to move a control element of the control valve until movement of the control element is within a desired range.</p> |
