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.

摘要： PROBLEM TO BE SOLVED: To prevent an operation switch from being freely operated by a third person since the display content can be understood when the third person looks at a display unit in the case where the operation switch of the display unit is arranged on the front face of a device. SOLUTION: In a flow rate correcting device 11, a display window 19 opposed to a liquid crystal display unit 18 arranged in a housing is arranged on the front face of a cover 17 of the housing. A key switch 20, a rotary switch 21 and a push-button switch 22 are arranged on the front face of the cover 17. The display content of the liquid crystal display unit 18 can be selectively switched by a combination of the key switch 20 and a rotary operation position of the rotary switch 21. Therefore, since a third person having no key to be inserted into the key switch 20 can not freely operate the display content of the liquid crystal display unit 18 in a switching system, mischief by the third person can be prevented.

摘要： PURPOSE: To provide a shut-off valve by which a sealing property between a valve seat and a valve element can be improved and leakage is hardly generated. CONSTITUTION: A shut-off valve is provided with a valve seat 2 opening as a flow passage and a valve element 3 which is freely brought close to or separated from the valve seat 2 so as to close or open the valve seat 2, and when the valve element 3 is brought into contact with the valve seat 2 against a pressure from the valve seat 2 side, the flow passage is cut off, and in the valve element 3, a contact surface 33a with the valve seat 2 is formed into a plane, while the valve seat 2 is formed projectingly toward the valve element 3 side. In this way, a contact surface 2a at the tip of the valve seat 2 is formed into a plane so as to be brought into tight contact with the contact surface 33a in the valve element 3, and a corner part 2c in which the contact surface 2a in the valve seat 2 and the inside face 2b in the valve seat 2 cross each other is formed into a circular arc, while on the contact surface 2a in the valve seat 2, the length L2 in the direction from the inside face 2b side to the outside face 2d side is set to be double of the length L1 of the corner part, 2c in the same direction or more.

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 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.
