Abstract
PURPOSE:To estimate the flow running in an automatic pressure regulating valve provided in a water pipe on the basis of the change of the opening degree of the valve, by recording the movement of a valve rod of the valve for a predetermined time period. CONSTITUTION:The opening degree of an automatic pressure regulating valve 2 is changed by the up-and-down movements of a valve rod 5 for regulating the pressure of the water running from a primary side to a secondary side of the valve 2. The above-mentioned change is recorded onto a disk chart over a predetermined time through a connecting conjunction member 3 and a recording pen driving mechanism 20. At the same time, one end of a hose 39 is connected to a nipple 33, with the other end thereof connected to the secondary side of the regulating valve 2, so that the pressure at the secondary side of the valve 2 is simultaneously recorded by a pressure detecting mechanism 36. Thus, the flow over the predetermined time period can be estimated on the basis of the change of the opening degree of the valve, and the pressure difference between at the primary and at the secondary sides of the valve.
