[0001] Discharge system of waste and sanitary water for submarine [

The present invention relates to an apparatus for discharging wastewater and sanitary water from a submarine, and more particularly, to a system for discharging wastewater and sanitary water from a submarine, .

Generally, a submarine has used a single piping and compressed air provided to discharge various sewage and sanitary water generated after use in various places such as a sink, a washstand, a shower room, and a large urinal .

FIG. 1 is a view showing a configuration of a waste water and sanitary water discharging device in a conventional submarine, and shows a process of collecting sewage and sanitary water into a storage tank.

In the figure, reference numeral 26 denotes a pressure hull of a submarine.

In this case, the open / close switching valve 14 corresponds to a one-way valve for controlling opening and closing of the pipeline on / off, and the flow path switching valve 24 is connected to the Way valve that performs a function of regulating the supply path to reach the storage tank 12 or to be discharged into the compartment through the vent pipe 22.

In particular, as shown in FIGS. 1 and 2, the opening / closing switching valve 14 and the flow path switching valve 24 collect various sludge and sanitary water into the storage tank 12, And performs a function of opening / closing the pipeline or switching the supply path of the compressed air in the process of discharging various kinds of wastewater and sanitary water stored in the tank 12 to the outside.

1, the open / close switching valve 14 is opened in the process of collecting various kinds of wastewater and sanitary water into the storage tank 12, and the flow path switching valve 24 is opened / And communicates between the tank 12 and the vent pipe 22 to prevent the compressed air from being supplied to the interior of the storage tank 12.
