Document Type and Number:
WIPO Patent Application WO/2015/037708
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a conduction detection device, a valve, and a container valve, with which the conduction of a fluid can be detected reliably. This conduction detection device (1) detects the conduction of a gas conducted through the interior, and is provided with: a device body (30) which is installed on a conduction path that permits conduction of a gas, and which has a rear enlarged-diameter portion (B4) permitting conduction of the gas; an orifice (60) which is arranged at a prescribed position in the rear enlarged-diameter portion (B4) and which is displaced in the conduction direction by the conduction of the gas; a coil spring (14) for returning the orifice (60) to the prescribed position once displaced in the conduction direction; and a leader magnet (50) which is installed in the orifice (60), and which is detected by a follower magnet (20) arranged to the outside of the device body (30).
