Abstract

PURPOSE: To determine the quality by the pressure loss at the time of valve operation, by gradually increasing the amount of flow to a test gas cock and holding and measuring the maximum instantaneous pressure loss at the time of operation of a excess flow preventing valve.
CONSTITUTION: To determine the quality of a gas cock fitted with an excess flow preventing valve, the valve opening ratio is gradually increased. Then, the amount of flow increases. When it exceeds a certain level, the excess flow preventing valve of test gas cock Y operates and the flow stops. The maximum pressure loss at this time is detected by pressure sensor A, and it is converted into an electrical signal by pressure generator B. Then, it is amplified by amplifier C to the measuring level and is transmitted to digital panel meter D, which displays the maximum pressure loss. Since the operational pressure loss at this time is charged to the output of governor Z instantly, the point of operational pressure loss change is held by means of measured value hold detector E, and by the hold circuit signal, the measured value of the point of change is displayed in digital panel meter D. Digital setter F performs lamp display, OK the measured value is below the preset upper limit, and NG when it is above the limit.
