In accordance with the present invention, disclosed is a pressure control valve for controlling a positive pressure in a ship protection zone, which comprises: a casing (110) coupled to a duct of a ventilation device installed in a ship protection zone; a guider (120) including a triangle bracket (121), a guide support (122), and a guide (123); a slider (130) including a spring holder (131), a disk plate (132), and a spring (133), and guided by the guide (123) to be elevated; and a cover (140) including a shaft (141), a cover flange (142) and a cap (143) for guiding the slider (130) to be slidably elevated. In accordance with the present invention, the shaft (141) exposed through the separation of the cap (143) is rotated forward and backward to vary the separation distance between the front end of the casing (110) and the triangle bracket (121). Therefore, the tension of the spring (133) is controlled by opening only the cap (143) without disassembling a product, such that a set pressure of a protection zone in a battleship can be easily and simply controlled when chemical, biological, and radiological situations occur.

    본 발명은, 선박 방호구역에 설치된 환기 장치의 덕트에 결합되는 케이싱(110); 트라이앵글 브라켓(121)과 가이드 서포트(122)와 가이드(123)로 구성되는 가이더(120); 스프링홀더(131)와 디스크 플레이트(132)와 스프링(133)으로 구성되어 가이드(123)에 의해 안내되어 승강하는 슬라이더(130); 및 슬라이더(130)의 승강 슬라이딩을 안내하는 샤프트(141)와 커버 플랜지(142)와 캡(143)으로 구성되는 커버(140);를 포함하여, 캡(143)의 분리를 통해 노출되는 샤프트(141)를 정역회전시켜 케이싱(110)의 전단과 트라이앵글 브라켓(121)과의 이격거리를 가변시켜, 제품분해없이 캡(143)만을 열어 스프링(133)의 장력을 조절하여 화생방 상황 발생시 전함 내 방호구역의 설정압력을 쉽고 간편하게 조절할 수 있는, 선박 방호구역의 양압조절을 위한 압력조절밸브를 개시한다.
