摘要： PROBLEM TO BE SOLVED: To provide a pressure regulator provided with a simple structure, and a pressure regulation function and a relief function at enough operation accuracy, the total length of which is short, enabling to simply perform exchange and attachment to piping in a short period of time. SOLUTION: The pressure regulator 1 is monolithicly provided with a relief valve 23 in a pressure regulator main body 11, and the pressure regulator main body 11 has a pressure regulation part 13 in a housing 12. A through hole 21a is provided on a bottom board 21 of the housing 12 so as to communicate with a passage 14. The relief valve 23 detects an abnormal rise in the secondary side pressure through the through hole 21a of the bottom board 21 to perform relief operations. The pressure regulation part 13 and the relif valve 23 are placed on the top and the bottom of the bottom board 21 so as to be integrated with sharing the bottom board 21, so that the length Li between surfaces of the pressure regulator 1 and a gas meter 2 becomes significantly shorter than conventional one.

摘要： PROBLEM TO BE SOLVED: To provide gas pressure reducing equipment and a gas pressure reducing method capable of miniaturizing the equipment, and reducing the number of times of operation of a system switching valve to reduce the failure of the valve.
SOLUTION: This gas pressure reducing equipment 1 comprises two pressure reducers 10, 11 mounted at an upstream side, and one air-fin type heater 20 mounted at a downstream side of the pressure reducers 10, 11. A gas of which pressure is reduced by one of two pressure reducers 10, 11 and cooled, is heated by the air-fin type heater 20. The circulating direction of a gas flowing in the air-fin type heater 20 is switched when a temperature detected by temperature sensors T1, T2 detecting a temperature of the gas flowing out from the air-fin type heater 20 is lowered than a prescribed range. A first injection opening is formed for injecting CNG to a primary-side flow channel 30 at an upstream side of the pressure reducers 10, 11, and a second injection opening is formed for injecting LNG to a secondary-side flow channel 40 in which the gas flowing out from the air-fin type heater 20 flows.

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
