摘要： PURPOSE: To provide a shutoff valve for damping a pressure fluctuation (pulsation) produced during flowing of a small amount and preventing this from being transmitted to a fluidic element side. CONSTITUTION: A float valve 29 with a diaphragm 30 is incorporated in a main valve 18 and gas is caused to flow by driving a main valve opening/closing device 28 so as to close the main valve 18 during flowing of a small amount via the diaphragm 30 of the float valve 29 and thus, a pressure fluctuation is damped by means of the up and down movement of this float valve 29 and the action of the orifice 30. When a shutoff valve 17 is closed in emergency, by closing the main valve 18, driving a float valve control device 37 and by means of a float valve control shaft 31, the float valve 29 is tightly contacted with a float valve sheet 23.

摘要： PURPOSE: To reduce the overall power consumption in a cutoff valve for gas meter capable of reducing the influence of pressure fluctuation of gas on a gas meter. CONSTITUTION: Main valve driving actuators 48a, 48b drive a main valve 41, and select the state where the main valve 41 covers an opening part 16a and the state where the main valve 41 opens the opening part 16a. An auxiliary valve driving actuator 50 drives an auxiliary valve 46 and selects the state where the main valve 41 covers the opening part 16a and the auxiliary valve 46 opens a first hole 44 and the state where the auxiliary valve 46 energizes the main valve 41 on the opening part 16a side, whereby the main valve 41 covers the opening part 16a, and the auxiliary valve 46 blocks the first hole 44. In the state where the main valve 41 covers the opening part 16a and the auxiliary valve 46 opens the first hole 44, a gas 53 is passed through the first hole 44, a gas housing chamber 43 and a second hole 45, and the pressure fluctuation of the gas 53 is reduced.

摘要： PURPOSE: To prevent an erroneous measurement generated at a time when a pressure is changed by constituting a cutoff valve in such a way that it can be opened fully and closed fully and, in addition, that it can control a low flow rate. CONSTITUTION: A slave valve sheet 15 is formed at a main valve 11, and a pressure-regulating chamber A is formed inside the main valve 11. When the flow rate is high, the main valve 11 is opened. When the flow rate is low, only the main valve 11 is closed and only the slave valve 15 is opened. Thereby, a gas is passed inside the pressure-regulating chamber A, and a pressure change is eliminated here so that the pressure change is not propagated to the side of a nozzle.

摘要： PROBLEM TO BE SOLVED: To improve workability in opening and closing a valve by manually operating a driven shaft of a shutoff valve of a valve element part, in the gas shutoff valve including the valve element part and the valve drive part.
SOLUTION: The valve drive part 2 is attached to the valve element part 1 only by a box shape lower case part 2A of the valve drive part 2. A valve driving motor 5 is stored in the lower case part 2A, and a main shaft 51, a pinion 61, a gear 62 and a drive shaft 7 are connected to the same. The drive shaft 7 of an upper case part 2B of the valve drive part 2 is kept in parallel with the lower case part 2A and is projected to the valve element part 1 side. The driven shaft 41 and the drive shaft of the ball valve 4 at the valve element part 1 side are connected by a connection pin 8. The driven shaft 41 is rotated by applying a spanner on a spanner apply part 41a of the driven shaft 41 under a condition where the connection pin 8 is pulled off. Rotation angle of the spanner is expanded so as to make a grip of the spanner abut only on the lower case part 2A. Operation is simplified by a structure requiring only removal of the connection pin 8 for manual operation.
