| abstract | The present invention relates to an inner tube which is connected to the pipe and becomes a passage for the fluid flowing through the pipe, a check valve installed inside the inner tube and allowing only fluid flow from the first end to the second end of the inner tube, It comprises an outer tube constituting the enclosed space, a ring-shaped piston for sliding reciprocating the sealed space between the inner tube and the outer tube, and an air innet mounted on the outer tube on the first end side of the inner tube. A communication hole is formed in the inner tube between the second end of the inner tube and the check valve so as to fill the space between the piston and the first end of the inner tube. The space between the piston and the second end of the inner tube is filled with fluid flowing through the pipe, and one end is inserted into the inner circumferential surface of the inner tube at each of the first end and the second end of the inner tube. A ball pipe in which a ball-shaped convex portion is formed, a ball-shaped concave portion corresponding to the ball-shaped convex portion of the ball pipe is formed at one end thereof, and a ball housing having a flange connected to the pipe at the other end thereof, and a ball pipe The water hammer preventer further comprises a joint configured to include an O-ring mounted between the convex portion and the recess of the ball housing. |
