LEAKAGE GAS DETECTION DEVICE, PIPING STRUCTURE WITH LEAKAGE GAS DETECTION DEVICE, COVER MEMBER WITH LEAKAGE GAS DETECTION DEVICE, AND LEAKAGE GAS DETECTION METHOD

Document Type and Number:

Japanese Patent JP2023117249

Kind Code:

A

Abstract:

To provide a leakage gas detection device which has a simple structure and can properly detect leakage gas at a stage of minute leakage at an early stage.SOLUTION: A leakage gas detection device 1 according to one embodiment comprises a cover member 10 and a measurement cap 20. The cover member 10 includes a cylindrical cover body 11 which extends in a direction in which a first piping part and second piping parts are continuous so as to surround the first piping part as a first pipe material 101 and the second piping parts (102-105) fluidly connected to the first pipe material 101. The cover member 10 is attached to the first piping part and the second piping parts. A first opening 14 is formed in the cover body 11. The measurement cap 20 is detachably attached to the cover body 11 so as to close the first opening 14 and includes an internal space 20S fluidly connected to the interior of the cover body 11.SELECTED DRAWING: Figure 1
