摘要： PROBLEM TO BE SOLVED: To provide a pressure-reducing device and an operation deciding method for readily deciding whether a reducing valve on the upstream side is in operating state, when a reducing valve on the downstream side breaks down. SOLUTION: The pressure-reducing device 1 is installed between an upstream side duct 3 and a downstream side duct 5, and configured by arranging a first reducing valve 10 and a second reducing valve 10' from the upstream side to the downstream side. The first reducing valve 10 and a second reducing valve 10' are direct-acting reducing valves configured similarly. The first reducing valve 10 maintains the gas pressure of the downstream side duct 5 to a first set pressure. When the gas pressure of the downstream side duct 5 does not exceed the first set pressure, the second reducing valve 10' sends gas, that is flowing through the upstream side duct 3, to the first reducing valve 10 without reducing the pressure; and when the gas pressure of the downstream side duct 5 exceeds a second set pressure value which is larger than the first set pressure, the gas pressure of the downstream side duct 5 is maintained so as not to exceed the second set pressure. Thus, a manometer 60 is installed on the connection channel 24 of the first reducing valvae 10 and the second reducing valve 10'. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a pressure governor device for achieving stable behavior when starting the pressure governor device even though a start and an operation stop are easily performed.SOLUTION: A motor-operated valve 30 is provided in a pilot passage 5 such that the motor-operated valve 30 can be subjected to an opening/closing operation to vary communication opening between an auxiliary ball 14 and a downstream side pipe 2. When the motor-operated valve 30 is closed to block the pilot passage 5, a main governor 11 stops operation in a closed state, and when the motor-operated valve 30 is opened, the pilot passage 5 is made to communicate to operate the main governor 11. When a start operation signal for starting the main governor 11 is outputted by remote control, control means restricts the speed of the motor-operated valve 30 to cause low-speed operation, thereby gradually increasing the communication opening of the pilot passage 5 by taking predetermined time within the range of cushioning opening smaller than communication opening during operation. When the predetermined time passes, the motor-operated valve 30 is opened completely to make the communication opening of the pilot passage 5 the communication opening during operation.

摘要： PROBLEM TO BE SOLVED: To provide a flow measurement device capable of easily specifying an accurate opening degree of a valve especially at an initial setup such as pipe installation.SOLUTION: A main valve is provided between an upstream pipe and a downstream pipe in an openable/closable state. An opening degree measurement device measures an actual displacement amount of the main valve on the basis of the open/close operation of the main valve. A secondary pressure gauge detects change in pressure of fluid in the downstream pipe when the main valve is opened in a state where the communication between the upstream pipe and the downstream pipe is blocked. The actual displacement amount of the main valve from the state where the communication between the upstream pipe and the downstream pipe is blocked until the secondary pressure gauge detects a predetermined pressure change is stored as a reference displacement amount. When flow is measured, the stored reference displacement amount is subtracted from the actual displacement amount measured by the opening degree measurement device to specify an opening degree of the main valve, and an estimated flow of the fluid in the downstream pipe is calculated on the basis of the opening degree of the main valve.
