Abstract

See full text

A valve body unit is configured to be disengaged from a stem by moving the stem and the valve body unit to a valve seat side in a state where a bonnet is separated from the valve seat, thereby pushing a replacement ring such that the replacement ring moves through the bonnet while decreasing in diameter and then drops down onto a ring dropping portion in the free state, then moving the stem, the valve body unit, and the replacement ring to an opposite side to the valve seat side such that a first surface comes into contact with a second surface and the ring dropping portion comes into contact with the replacement ring, and in this state, moving only the stem to the opposite side to the valve seat side such that the connection formed by a connecting mechanism between the stem connection portion and the stem is released.
