摘要 |
A method of draining a standpipe includes moving a valve control device toward a closed position sufficient to uncover at least one drain hole before the valve control device achieves a fully closed position, the at least one drain hole being disposed in a slot of a saturation ring and draining a contents of the standpipe through a drain route to an external portion of the standpipe, the drain route is defined by the drain hole in the valve seat ring, drain ports in the drain ring, outlet notches and a drain channel in the saturation ring. The drain hole is radially offset from each of the drain ports in the drain ring and each of the drain ports are radially offset from each of the outlet notches in the saturation ring. A valve control device is also disclosed. |

1. A method of draining a standpipe comprising:
moving a valve control device toward a closed position sufficient to uncover at least one drain hole before the valve control device achieves a fully closed position, the at least one drain hole being disposed in a slot of a valve seat ring; and draining a contents of the standpipe through a drain route to an external portion of the standpipe, the drain route is defined by the at least one drain hole in the valve seat ring, a plurality of drain ports in a drain ring, a plurality of outlet notches and a drain channel in a saturation ring, the drain route providing a fluid communication route between an outlet portion of the valve seat ring in the standpipe and an external portion of the standpipe, wherein each of the at least one drain hole in the valve seat is radially offset from each of the plurality of drain ports in the drain ring and wherein each of the plurality of drain ports are radially offset from each of the plurality of outlet notches in the saturation ring. |
