PURPOSE: A check valve is provided to reduce noise as a fluid pressurization member receives the power by the flow of the fluid and presses a valve body at a right angle to a flow path, thereby removing crash sound when a valve body collides into the pipe. CONSTITUTION: A check valve comprises a circular plate(14), a valve body(1), and a fluid pressurization member. The valve body has multiple guide units(11,12) projected from the outer circumference of the circular plate. The valve body is inserted to the inside between a valve seat part(20) and a stopper installed within a pipe(10). The path of the fluid is formed on the outer circumference of the circular plate. The fluid pressurization member is installed on the valve body. |
