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 provide a gas cutoff device provided with the function to detect a closed state and raise an alarm informing when a cut-off valve cuts off a gass passage due to the shock. SOLUTION: When a cutoff valve closes a plug and moves, a valve drive section 4 outputs a cutoff valve release signal B. When the cut-off valve release signal B is outputted due to the shock, since a cut-off request signal A is not outputted from a valve drive request section 3, a shock signal input section 5 judges to have been the shock and outputs a shock detect signal C. Since a shock judgment delay section 6 outputs the shock judgment request signal E after a prescribed delay time lapsed, an open and close valve judgment section 7 confirms the opened and closed state of the cut-off valve and when the closed state is detected, it outputs an alarm informing signal D and an alarm information is raised from an alarm informing section 8. Since the open and closed valve is judged after the vibration is settled by setting up the said delay time, no misjudgment is made.

摘要： PROBLEM TO BE SOLVED: To provide a shut-off valve having a hardly broken mechanism for fixing a stator to a flange in use over a long period of time and having high airtight reliability and action reliability in which leakage of a gas does not occur even if it is destroyed by any chance in the shut-off valve in which a rotation drive mechanism used for a micro-computer meter is used as a power source and a motion part and a fixed part are made airtight.
SOLUTION: Since a mechanism for fixing the stator 46 to a mounting plate 57 is made to a support frame 59 and the support frame 59 and a fitting part 57c are formed at the outside more than a sealing surface 57e of the mounting plate 57, the fitting part 57c completely exists at an atmosphere chamber side and is hardly destroyed. Even if it is destroyed by any chance, the shut-off valve having high airtight reliability in which leakage of the gas does not occur can be provided.

摘要： PROBLEM TO BE SOLVED: To provide a shutoff valve highly reliable for airtightness with little change in the compression rate of a seal member even in a long-term use. SOLUTION: An elastic seal member 58 is circumferentially compressed and arranged between the outer surface of the cylindrical part 47c of a bulkhead 47 and the inner surface of the stepped part 57b of a mounting plate 57. According to this, even if a slight axial slippage between the bulkhead 47 and the mounting plate 57 is caused by the clearance of a caulking part in assembling, or the fixation of the bulkhead 47 to the mounting plate 47 is loosened by corrosion or thermal expansion during a long-term use, the compression rate of a seal member 80 is hardly influenced thereby.
