PURPOSE: A check valve of Freon gas for refrigerant is provided to control fluid to flow slack in streamline by a buffed protrusion, and to allow large amount of fluid to flow without resistance. CONSTITUTION: A spring(130) has one end inserted into a protrusion(140) formed on one side of a check valve(100), and the other end allowing a screw protrusion(120) to be inserted thereto. Fluid is introduced into a tube(110), and flows in streamline due to the semi-circular screw protrusion. The screw protrusion is placed around an inlet of the tube, and is pushed by introduced fluid. The streamlined screw protrusion is pushed back by introduced fluid and slows down flow of fluid to control flow rate of fluid. The spring is inserted to the screw protrusion, and controls movement of the screw protrusion. A rectangular shape is formed integrally with the protrusion part, and penetrate wide to allow fluid to be discharged without loss. The protrusion part secures a channel for fluid easily more than an existing opening and closing wing, and generates less resistance to allow fluid to freely move.
