<p>PROBLEM TO BE SOLVED: To simplify a constitution and to stably prevent reverse flow by providing a body arranged in a passage of a pipe and a flexible tube which can be freely bent by hydraulic pressure when the fluid flows in a reverse direction in the pipe. SOLUTION: A body 20 is arranged in one side of a passage 20a formed in a pipe 1 and the fluid flowing through a flow-out hole 20b flows along the outer wall of the body 20 in a normal direction and a flexible tube 21 which prevents the reverse flow by bent portion is arranged. At least one flow-out hole 20b through which fluid flowing-in through the passage 20a is discharged is made and a sealing member 23 for preventing a water leak is arranged at the other end of the body 20. A projection 20c for preventing the sealing member 23 from being removed is formed at one end of the body 20 and a projection 20d for hermetically fixing the tube 21 is formed at one side of the outer periphery of the body 20.</p> |
