Embodiment Construction
[0025] Below in conjunction with embodiment and attached Figure 1-2 The present invention is further described, but the present invention is not limited.
[0026] A closable non-return type automatic drain device, mainly including a body 1, a control rod 2, a stop plate 3, a spring 6, an operating head 7, a sealing gasket 8 and a welding seat plate 9; the upper end of the body 1 is hollow Cylindrical barrel, the lower part of the hollow shrinking cone is connected to the bottom of the barrel, the upper edge of the barrel extends outwards to form a ring-shaped table, and a body support rib is set between the edge of the lower end of the ring-shaped table and the bottom of the barrel; welding seat plate 9 It is directly welded to the bottom of the deck 11 or the sewage well 10, the inner side of the upper end of the seat plate 9 is a stepped bayonet, the upper end surface is flush with the bottom of the deck 11 or the sewage well 10, and the lower end surface is in contact with...

The invention relates to a closable non-return automatic water discharging device, comprising a main body, a control rod, a baffle, a spring and a sealing cushion. On automatic state, when the water level of water draining outlet of the device is higher than the installation plane by certain height, the access of the device automatically opens and discharges water; the opening of the drainage channel increases with the increase of the water level height; when the water level is not lower than set full gate height, all the drainage channels open automatically and maximum flow water draining isachieved. On open state, the device is always on open state that is the water draining outlet of the engine room is kept in communication with the water draining pipeline, and as long as there is water around the automatic water discharging device, it can be discharged. When the left water is discharge, the action force of the spring on the lower part of the baffle makes the baffle reciprocate toachieve the non-return function, and stay on always close state, and stop the communication between the water draining outlet and the water discharging pipeline and stop water discharging. The automatic non-return function can prevent overboard water from entering the dewatering cabin after naval vessel is damaged and sunken, and water from flowing between cabins.
Description
technical field [0001] The invention belongs to the technical field of water drainage in ship cabins, and in particular relates to a drainage device for water drainage in ship cabins. Background technique [0002] On a ship, there are a large number of compartments (such as living compartments such as kitchens, dining rooms, shower rooms, lavatories, and other equipment compartments and mechanical spaces that may cause water accumulation) that need to be provided with drains to discharge the accumulated water in the cabins. Drainage pipes are generally partitioned and combined nearby, and discharged on the full-load waterline. Multiple cabins on several decks share one side discharge outlet. The available drainage devices are generally straight-through deck leaks and deck leaks with cut-off function. The existing method has the following problems: 1. During normal use, due to the shaking of the ship, the sewage on the upper deck may overflow from the leak on the lower deck, ...
