摘要： PROBLEM TO BE SOLVED: To perform stable and easy assembly and maintenance against press in a release position. SOLUTION: Upper and lower valve element end parts are provided with respective packings 10 making contact with the inside diameters of respective valve seats. One valve element 7 is provided with a central packing 11 operated adjacently to a valve stem in a valve release position. Meanwhile, the other valve element is provided with a seal collar 12. When the central packing 11 is adjoined with a valve stem situated in a valve release position, sealing of a leak reservoir space 9 is ensured.

摘要： PURPOSE:To eliminate only the exception in an opening and closing condition from combination of the opening and closing condition of plural kinds, by providing a subsolenoid valve in a passage of control fluid. CONSTITUTION:A control device, turning on a main switch 14, closes a pneumatic actuator valve AO1 by opening a main solenoid valve 15 so as to feed high pressure air to the pneumatic actuator valve AO1. While the control device, if it turns on a subswitch 18 at this time, opens a pneumatic actuator valve AO2 by opening a subsolenoid valve 19 so as to feed the high pressure air to the pneumatic actuator valve AO2. A condition that the pneumatic actuator valves AO1, AO2 are both opened can be eliminated from combination of the opening and closing condition of the pneumatic actuator valves AO1, AO2. Both of the valves AO1, AO2 are never opened even if it is required that gas should not be simultaneously supplied from both lines 11, 12.

摘要： PURPOSE:To prevent the simultaneous closure of multiple shutoff valves by opening or closing individual shutoff valves in an interlock action so as to ensure a state that at least one or the other is kept opened when safety valves are to be switched. CONSTITUTION:In order to close shutoff valves 2A, 3A and stop safety valve 1A, spacers 6, 7 must be moved out from between handles 22A, 32A and buffleplates 4A, 5A and must be allowed for access to the handles 22A, 32A. However, the spacers 6, 7 can not be moved out by being interrupted by baffleplates 4B, 5B of shutoff valves 2B, 3B. In order to rotate said spacers 6, 7 further, shutoff valves 2B, 3B must be opened. Thereby, the simultaneous closure of multiple shutoff valves can be prevented.
摘要翻译：目的：为了防止在互锁动作中打开或关闭单个截止阀同时关闭多个截止阀，以确保在要切换安全阀时至少一个或另一个保持断开的状态。构成：为了关闭截止阀2A，3A并停止安全阀1A，间隔件6,7必须从手柄22A，32A和抛光板4A，5A之间移出，并且必须允许进入手柄22A，32A。然而，间隔件6,7不能被截留阀2B，3B的挡板4B，5B中断。为了进一步旋转所述间隔件6,7，必须打开截止阀2B，3B。由此，可以防止同时闭合多个截止阀。
