Valve system
The valve system with offset connections and multiple purge valves addresses the inefficiencies in conventional purging methods by creating longer purge paths and reducing dead-end areas, enhancing purging efficiency and substance recovery in H-shaped piping systems.

Abstract
To provide a valve system which can easily perform a desired purge.SOLUTION: A valve system 10 includes: an upstream valve 15; a downstream valve 16; an equal pressure valve 22; a first purge valve 25; and a second purge valve 26. The upstream valve 15 opens and closes an upstream branch pipe 13 on an upstream side of an orifice 12 of a main pipe 11. The downstream valve 16 opens and closes a downstream branch pipe 14 on a downstream side of the orifice 12 of the main pipe 11. An upstream connection pipe 17 connects the upstream valve 15 to an upstream takeout part 19. A downstream connection pipe 18 connects the downstream valve 16 to a downstream takeout part 20. The equal pressure valve 22 opens and closes an equal pressure connection pipe 21 connecting the upstream connection pipe 17 to the downstream connection pipe 18. The first purge valve 25 opens and closes a first purge pipe 23 connected to the upstream connection pipe 17 and a first purge coupler 27. The second purge valve 26 opens and closes a second purge pipe 24 connected to the downstream connection pie 18 and the second purge coupler 28.SELECTED DRAWING: Figure 1
