The present invention relates to a method of draining a tank (2) having a plate, the plate (12) including a canister (19) having an outer casing (20) provided with a base (19′) that is pressed against the plate (12), the base (19′) presenting at least one through orifice (21) suitable for being clos
The present invention relates to a method of draining a tank (2) having a plate, the plate (12) including a canister (19) having an outer casing (20) provided with a base (19′) that is pressed against the plate (12), the base (19′) presenting at least one through orifice (21) suitable for being closed by a movable member (22) of the canister (19), the plate (12) carrying a pump (30) that co-operates with the canister (19) by actuating the movable member (22) to open the through orifice (21), during which method the pump (30) is removed from the canister (19) and then a fluid connector (50) is inserted to take the place of the pump (30), the fluid connector (50) co-operating with the canister (19) by actuating the movable member (22) to release the through orifice (21) in order to drain the tank (2) via the fluid connector (50).

1. A method of draining a tank having a plate presenting an inside face facing the inside (INT) of the tank and an outside face opposite from the inside face, the plate including a canister having an outer casing provided with a base that is pressed in leaktight manner against the plate and that def
1. A method of draining a tank having a plate presenting an inside face facing the inside (INT) of the tank and an outside face opposite from the inside face, the plate including a canister having an outer casing provided with a base that is pressed in leaktight manner against the plate and that defines an opening in the plate, the base presenting at least one through orifice suitable for being closed by a movable member of the canister, the plate carrying a pump that co-operates with the canister by actuating the movable member to open the through orifice, the method comprising the steps of: removing the pump from the canister; and theninserting a fluid connector to take the place of the pump, the fluid connector co-operating with the canister by actuating the movable member to open the through orifice in order to proceed with draining the tank via the fluid connector. 2. A method according to claim 1, wherein the fluid connector is connected to a valve, and after the fluid connector has been inserted to take the place of the pump, the valve is opened. 3. The method of claim 1, wherein the fluid connector has a slot and the fluid connector, when cooperating with the canister, fluidly connects the slot in the fluid connector with the through orifice. 4. A device for quickly draining a tank and suitable for implementing the method according to claim 1, the tank being provided with a plate presenting an inside face suitable for facing the inside (INT) of the tank and an outside face opposite from the inside face, the plate including a canister having an outer casing provided with a base that is pressed in leaktight manner against the plate and that defines an opening in the plate, the base presenting at least one through orifice suitable for being closed by a movable member of the canister, the plate carrying a removable pump that co-operates with the canister by actuating the movable member to open the through orifice, wherein the device comprises a hollow and removable fluid connector suitable for being arranged to occupy the place of the pump in order to co-operate with the movable member. 5. A device according to claim 4, including a valve in fluid flow connection with the fluid connector. 6. A device according to claim 4, including a discharge pipe connected to the fluid connector either directly or via a valve interposed between the discharge pipe and the fluid connector. 7. A device according to claim 6, wherein the discharge pipe is in fluid flow connection via fastener means with a drain container. 8. A tank, including a device according to claim 4. 9. An aircraft, including a tank according to claim 8. 10. A device for draining a tank, the tank being provided with a plate presenting an inside face suitable for facing the inside of the tank and an outside face opposite from the inside face, the plate including a canister having an outer casing provided with a base that is pressed in leaktight manner against the plate and that defines an opening in the plate, the base presenting at least one through orifice suitable for being closed by a movable member of the canister, the plate carrying a removable pump that co-operates with the canister by actuating the movable member to open the through orifice, wherein the device comprises: a removable fluid connector suitable for being arranged to occupy the place of the pump in order to co-operate with the movable member to actuate the movable member to open the orifice, the fluid connector having a hollow body provided with a top edge suitable for co-operating with the movable member, the body including at least one slot in register with a through orifice in the canister when the body is inserted in the canister. 11. A device according to claim 10, including a valve in fluid flow connection with the fluid connector. 12. A device according to claim 10, including a discharge pipe connected to the fluid connector either directly or via a valve interposed between the discharge pipe and the fluid connector. 13. A device according to claim 12, wherein the discharge pipe is in fluid flow connection via fastener means with a drain container. 14. A device according to claim 10, further comprising a first sealing gasket disposed on the hollow body on a first side of the slot and a second sealing gasket disposed on the hollow body on a second side of the slot. 15. A device according to claim 10, wherein the top edge of the hollow body is a circular edge shaped to match a bottom edge of the movable member. 16. A tank, including a device according to claim 10. 17. An aircraft, including a tank according to claim 16. 18. A method of draining a tank having a plate, the plate including a canister having an outer casing provided with a base that is pressed against the plate and that defines an opening in the plate, the base presenting at least one through orifice suitable for being closed by a movable member of the canister, the plate carrying a pump that co-operates with the canister by actuating the movable member to open the through orifice, the method comprising: removing the pump from the canister; and theninserting a fluid connector into the canister, the fluid connector having a hollow body provided with a top edge suitable for co-operating with the canister by actuating the movable member to open the through orifice, the body including at least one slot in fluid communication with the through orifice in the canister when the body is inserted in the canister in order to proceed with draining the tank. 19. A method according to claim 18, wherein the at least one slot is in register with the through orifice in the canister when the body is inserted in the canister. 20. A method according to claim 18, wherein the fluid connector is connected to a valve, the method further comprising opening the valve after the fluid connector has been inserted to take the place of the pump.
