SAFETY CAP OF PRESSURE VESSEL AND PRESSURE VESSEL HAVING THE SAME

摘要

The present invention is a safety stopper for releasing the pressure fluid to the outside when the pressure inside the pressure vessel reaches a certain pressure in the state in which the pressure vessel accommodates the pressure fluid therein, the upper and lower ends are open cylindrical and penetrates to the side A first cover in which a ball is formed and a locking jaw is formed at an inner circumference; An opening and closing member configured to move the inner circumference of the first cover in a vertical direction and to open and close the through hole; A second cover coupled to an upper end of the first cover; And a spring disposed between the opening and closing member and the second cover to pressurize the opening and closing member downward.;Pressure vessel, safety cap, overpressure, first cover, second cover
