Provided is a sea chest ventilation system for a ship to block seawater discharge from a sea chest through a ventilation pipe, when the ship is in motion. The sea chest ventilation system comprises: a ventilation pipe comprising a first ventilation pipe forming a connection hole at an end thereof, and a second ventilation pipe having an inner diameter at least smaller than that of the first ventilation pipe but having an end connected to the connection hole of the first ventilation pipe; and an on-off valve which opens and closes the connection hole according to the height of the seawater in the first ventilation pipe. The on-off valve may include: a support bracket fixed to the second ventilation pipe; a floating body having an outer diameter at least larger than that of the connection hole and being able to float by the seawater in the first ventilation pipe; and a lifting guide which connects between the support bracket and the floating body.

    선박의 유동시, 환기 파이프를 통한 씨체스트의 해수 배출을 차단하기 위한 선박의 씨체스트 환기시스템은 제공된다. 이 씨체스트 환기시스템은 단부에 연결홀을 형성하는 제1 환기관과, 단부가 제1 환기관의 연결홀에 연결되되 제1 환기관보다 적어도 더 작은 내경을 갖는 제2 환기관을 포함하는 환기 파이프와, 제1 환기관 내 해수의 높이에 따라 연결홀을 개폐하는 개폐 밸브를 포함하고, 개폐 밸브는 제2 환기관에 고정 설치되는 지지브라켓과, 연결홀보다 적어도 큰 외경을 갖고, 상기 제1 환기관 내 해수에 의해 부유 가능하는 부유체와, 지지브라켓과 부유체 사이를 연결하는 승강 가이드를 포함할 수 있다.
