５とせられている。A door stop hardware 14 is fixed to one stream side end of the downstream pipe 13, and a door groove 1 is provided between the door stop hardware 14 and the orifice 1.
It is said to be 5.

17 is attached to the side end surface of @2 via the base plate 18, Pol I 19,
It is a side guide shoe fixed by a nut 20, and 21 is a side door stopper.
２２は空気供給管で、扉２の下流側に生ずる流水の縮流
周部に空気を供給するもので゛ある。Reference numeral 22 denotes an air supply pipe that supplies air to the circumference of the contracted flow of flowing water that occurs downstream of the door 2.

Even if there is a part where the rear end surface 3A of the seal ring does not come in contact with the skin play 2A of the door 2, the water will be stopped by the water stop rubber 5, and a complete water stop effect will be obtained. Since it is installed in a part that is not exposed to running water, it does not suffer from wear and tear due to running water or dirt, has a long lifespan, and has the advantage of perfecting its water-stopping effect.
