PURPOSE: A safety valve for a gas container tap is provided to be automatically set up with KS standard pressure by controlling the assembly position of a pressure adjusting body. CONSTITUTION: A safety valve for a gas container tap comprises a safety valve body(110), a spring(120), an insulating member(130), and a pressure controlling body(140). A gas passage and a space(113) are formed inside the safety valve body. A female screw part is formed at the end of the safety valve body, and an end protrusion is formed on the inner wall of the safety valve body. The spring is located in the space and applies elastic force. The insulating member is supported by the spring and flexibly blocks the gas passage. The pressure controlling body pressurizes the spring.
