装置。(1) A sanitary valve in which a valve stem 2 and a sleeve 4 fitted onto the valve stem 2 move in and out of a valve body 1, and a bellows 3 surrounds and seals a portion of the sleeve 4 inside the valve body, The sleeve, which moves together with the valve stem 2, has a through hole 5 at a position that remains inside the bellows even when the valve stem moves, and is arranged above the valve stem 2.
In addition, detection holes 7 are formed at positions outside the lid 6 of the valve box by movement of the valve stem, and the outer surface of the valve stem 2 and/or the inner surface of the sleeve 4 are connected to the conduction hole 5 and the detection hole 7. A space is formed between the valve stem 2 and the sleeve 4 by cutting across both positions, and the conduction hole 5 and the detection hole 7 are electrically connected through the space, and the bellows 3 is broken into the detection hole 7. 1. A bellows seal leak detection device, which detects fluid leakage by inducing fluid leakage when the bellows seal leaks.
