Claims

[Claims for Utility Model Registration] 1. Inflow channel 2 formed in valve casing 1
In a valve constructed by connecting a diaphragm 8 to a valve body 6 which can freely open and close the communication portion between the diaphragm 8 and the discharge passage 3, the valve casing 1 faces the diaphragm 8 and the diaphragm 8 is movable toward and away from the valve body 6. By providing a hole 11 on the inner wall surface that is closed by the diaphragm 8 when the valve is closed and opened when the valve is opened, the fluid inside the valve casing 1 can be prevented from flowing out through the hole 11 when the valve is open. A valve characterized in that it is configured to detect with a detection means 13 and output a detection signal to the outside. 2. The valve according to claim 1, wherein the detection means 13 is a pressure switch provided on a pipe 14 connected to the hole 11.
