手动开闭阀
摘要：
提供一种手动开闭阀，即使在维修时储气瓶的最大气体压直接作用于手动开闭阀的情况下，也不会发生气体泄漏。通过使把手(11)旋转，使阀芯(22)移动而与阀座构件(29)抵接，从而将输入口(30)与输出口(31)隔断的手动开闭阀(1)的特征在于，抵接产生的隔断状态包括：把手(11)旋转至第一角度θ1＝70度时的第一隔断状态；在把手(11)旋转至第二角度θ2＝90度时，将向把手(11)的旋转操作力转换成向阀座构件(29)的隔断载荷而施加的第二隔断状态。
摘要（英）：

A manual opening/closing valve includes a manual handle, a valve element, a valve seat, an input port, and an output port. The manual opening/closing valve is arranged to move the valve element into contact with the valve seat when the manual handle is rotated, so that the valve is placed in a cutoff state in which communication between the input port and the output port is cut off, wherein the cutoff state includes a first cutoff state established when the manual handle is rotated to a first angle and a second cutoff state established when the manual handle is rotated to a second angle at which rotation operation force to the manual handle is converted to a cutoff load to be applied to the valve seat.
