VALVE ELEMENT WITH CHECKING FUNCTION AND VALVE INCORPORATING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a valve such that wasteful costs can be reduced and consumables are easily replaced. SOLUTION: This valve comprises a valve main body part 2, a check valve 3 and a holding metal fitting 4. A locking groove 8 for receiving an operating shaft is formed on the outer periphery of the valve main body part 2 and a mounting part 7 for mounting the holding metal fitting 4 therein is formed on the inner periphery of the valve main body part 2. The check valve 3 comprises an outer cylinder that is liquid-tightly engaged with the inner periphery of the valve main body part 2 and an inner valve that is held within the outer cylinder and energized in the upstream direction. The holding metal fitting 4 is freely removably positioned at the mounting part 7. Thus, the check valve 3 is replaceable while the valve main body part 2 is held attached to an object apparatus.
