Abstract

PURPOSE: To enable judgement of goodness or not of the cock to be surely done by displaying the maximum pressure loss and maximum flow rate when the overflow preventing valve of the cock has operated in correspondence to the set values.
CONSTITUTION: When a governor Z1, valve V1 and laminar flowmeter A are interposed between the gas cock y to be tested and a pressure gas source and the opening ratio of the valve V1 is gradually increased, then the flow rate increases. When the flow rate increases a fixed rate, the overflow preventing valve of the cock Y operates to stop the flow. The maximum pressure loss of this time is sensed with a pressure sensor N, and is converted to a voltage signal by a pressure transmitter 0. This signal is then transmitted to a digital panel meter R which indicates the maximum pressure loss. The change point of the pressure loss at this operation is held and the measured value is indicated in the meter R. At the same time, a lamp OK or NG is lighted for the upper limit value by a setter Q. Further, OK or NG display for the peak value of the working flow rate is accomplished with respect to the upper limit value and lower limit value of the setter G.
