The invention discloses an in-cabin positive pressure maintaining system and a ship. The in-cabin positive pressure maintaining system comprises a cabin door detection circuit, an air source, an electric valve, an electromagnetic valve, an electric valve control circuit and an electromagnetic valve control circuit. The electric valve is controlled to be opened through the electric valve control circuit, so that the air source supplies air to the cabin, the micro-positive pressure of the cabin relative to the outside is maintained, outside harmful gas is prevented from entering the cabin, and the safety of the ship is improved. In addition, a buffer chamber is arranged between the cabin and the outside, and when the cabin door detection circuit detects that the outer door is opened, the electromagnetic valve control circuit controls the electromagnetic valve to be opened, so that the air source supplies air to the buffer chamber, micro-positive pressure of the buffer chamber relative to the outside is maintained, and external air is prevented from entering the buffer chamber. And meanwhile, the buffer chamber plays a role in buffering, so that external high-concentration harmful gas is prevented from directly entering the cabin.
本发明公开一种船舱内正压维持系统及船舶,包括舱门检测电路、气源、电动阀、电磁阀、电动阀控制电路和电磁阀控制电路。通过电动阀控制电路控制电动阀开启,以使气源向舱室供气,维持舱室相对于外部的微正压,避免外界有害气体进入舱室内,提高了船舶的安全性。此外,在舱室与外部之间设置缓冲室,舱门检测电路检测到外门开启时,电磁阀控制电路控制电磁阀开启,以使气源向缓冲室供气,维持缓冲室相对于外部具有微正压,避免外部气体进入缓冲室。同时,缓冲室起到缓冲作用,避免外界高浓度有害气体直接进入舱室内。
