<p>The present invention relates to a door for a casing of a submarine. The purpose of the present invention is to remove factors causing noises caused by a gap between a pressure hull and the casing during sailing and to decrease performance of being detected by enabling seawater to flow in and out from an open water flow section by a pressure difference between the inner and outer sides of the casing according to the diving depth of the submarine. To achieve the described purposes, the door for the casing of the submarine is composed of a door (10) for discharging seawater and a door (30) for receiving seawater installed on an opening (9) penetrating through the casing (3) of the submarine respectively. The door (10) for discharging seawater includes a first door plate (12) installed to be moved to outward to the opening (9); a first guide plate (14) protruding on the inner surface of the casing (3) inward to the first guide plate; a locking plate (16) forming a bored portion (20) and protruding on the rear surface of the first door plate (12) inward to the opening (9); and a first return spring (18) installed between the inner surface of the casing (3) and the locking plate (16). The door (30) for receiving seawater includes a second door plate (32) installed to be moved inward to the opening (9); a second guide plate (34) protruding on the inner surface of the casing (3) inward to the opening (9); and a second return spring (38) installed between the rear surface of the second door plate (32) and the second guide plate (34).</p> |
