簡便に検出することができる。 When the valve is operated, the displacement caused by the operation is repeatedly transmitted to the life detection member by the transmission member provided with the operation portion, the number of times the valve is operated. By suitably designing the stress transmitted by the transmission member and the material and shape of the life detection member, the life detection member causes fatigue failure after a certain number of operations and indicates the end of the valve life. Therefore, the actual number of times the valve is operated can be measured and the life span can be easily detected.
