일반적으로 안전밸브는 기기나 배관의 내부압력이 일정한 압력을 넘을 경우에 자동으로 작동하여 배기시켜서 압력의 상승을 방지한다.In general, the safety valve automatically operates and discharges when the internal pressure of the device or piping exceeds a certain pressure, thereby preventing the pressure from rising.

이와 같은 안전밸브는 가정용 보일러에서부터 산업용 보일러, 석유정제시설, 석유화학 플랜트, 제련소, 펄프공장 등 산업 전반에 폭넓게 사용되고 있으며, 크기, 압력, 설비의 조건에 따라 구성되는 안전장치이다.Such safety valves are widely used in industrial fields such as domestic boilers, industrial boilers, petroleum refining facilities, petrochemical plants, smelters, pulp mills, etc., and are safety devices which are formed according to size, pressure and equipment conditions.

한편, 24시간 연속적으로 가동되는 해당 설비나 장치는 현장의 조건에 맞는 안전밸브가 압력에 관련된 각 공정을 안전하게 보호함으로써 항상 정상적인 가동이 가능하다.On the other hand, the 24 hour continuous operation of the equipment or the device can be operated normally by safely protecting each process related to the pressure by the safety valve according to the conditions of the site.

이와 같은 안전밸브의 기능이 정확하게 작동되지 않으면 해당 설비나 장치가 폭발이나 파손되는 등의 산업안전사고로 이어지게 되어 인명 피해가 발생하거나 해당 설비나 장치가 크게 손상된다.
If the function of the safety valve is not operated correctly, it will lead to industrial safety accidents such as explosion or breakage of the facility or equipment, causing damage to the person or damage to the equipment or equipment.
