Document Type and Number:
WIPO Patent Application WO/2018/154932
Kind Code:

Abstract:
A lid member 24 of a valve device 6 can be attached to and detached from a main housing 21 secured to a casing 5. A connecting pipe is attached to the lid member 24. A pipe joint 40 is connected to piping secured to the casing 5. When the lid member 24 is installed on the main housing 21, the connecting pipe is inserted into the pipe joint 40 connected to the piping 11. Therefore, the lid member 24 can be installed on the main housing 21 in a state in which the lid member is disposed in a fixed position relative to the main housing 21. In addition, when the lid member 24 is removed from the main housing 21, the connecting pipe 25 is removed from the inside of the pipe joint 40, and a state is maintained in which the piping 11 connected to the pipe joint 40 is disposed in a fixed position within the casing 5 without moving together with the lid member 24. Therefore, it is possible to prevent the piping 11 from obstructing the work of a worker.
