is suspended by an elevating arm 4, and the outlet 1 is opened and closed by a gate plate 3. A water stop plate 5 is provided on the wall body 2 along the periphery of the outlet 1, and the water stop plate 5 shuts off water between the gate plate 3 and the wall body 2. Further, a first wedge plate 6 is provided on the back side of the gate plate 3, and this first wedge plate 6 has an inclined surface 6a that approaches the outlet 1 as it goes downward. And the first
A second wedge plate 7 is provided in front of the wedge plate 6 , and this second wedge plate 7 is supported by the wall body 2 via a support fitting 8 . Slope 6
It has an inclined surface 7a corresponding to a. Therefore, when the outflow port 1 is fully opened by the gate plate 3, the inclined surface 6a of the first wedge plate 6 and the inclined surface 7a of the second wedge plate 7 come into sliding contact, and the gate plate 3 becomes the water stop plate due to the wedge action. Pressed to 5.

ものである。Means for Solving the Problems In order to solve the above problems, the present invention provides a door body that moves in and out along a wall in which an outflow port is formed and opens and closes the outflow port, and a door body that opens and closes the outflow port. The first one is fixed at a position in front of the wall.
a wedge plate, and a second wedge plate provided on the door body corresponding to the first wedge plate, and the sliding contact between the first wedge plate and the second wedge plate allows the flow to be controlled. In a water control door in which the door body is pressed against a wall body as the exit is closed, a protrusion that comes into sliding contact with the sliding contact surface of the second wedge plate is attached to the sliding contact surface of the first wedge plate along the sliding direction. The configuration is such that the

Therefore, even if a dust layer adheres to the sliding contact surface of the first wedge plate, this dust layer does not participate in the sliding contact between the first wedge plate and the second wedge plate, and is always at a constant position. A wedge effect can be applied to the door body with the force of.

3 is provided. A door body 14 is disposed in front of the outlet 12, and this door body 14 is swingably supported via a support shaft 16 by a drive arm 15 that drives up and down. Further, a first wedge plate 17 is provided at a position in front of the wall body 11 via the door body 14, and this first wedge plate 17 is supported by the wall body 11 via a support fitting 18. -It is. In addition, the door body 1 of the first wedge plate 17
4 is formed on a first sliding surface 17a, and this first sliding surface 17a is inclined so as to be spaced apart from the upper door body 14. A second wedge plate 19 is provided on the front side of the door body 14 at a position corresponding to the first wedge plate 17.
The front surface of #I2 is formed as a second sliding surface 19a, and the sliding surface 19a of #I2 is inclined so as to approach the door body 14 on the lower side. and the first wedge plate 1
A plurality of protrusions 20 are provided on the first sliding surface 17a formed in the first sliding surface 17a along the sliding direction of the first sliding surface 17a, that is, the vertical direction. Further, the height of this protrusion 20 is about 0.1 mm.

is in sliding contact with the protrusion 20 provided on the first sliding surface 17a and the second sliding surface 19a, and the door body 14 is brought into contact with the water stop plate 6 due to the wedge action caused by the sliding of both layers 17a and 19a. is pressed against. Therefore, the thickness of the first sliding contact surface 17a is 0.
Even if a dust layer 21 of about 1M is attached, this dust layer 21
does not participate in the sliding movement of the first wedge plate 17 and the second wedge plate 19, so that a wedge action of a constant force can always be applied to the door body 14 at a constant position. For this reason, the door body 14
And no overload is applied to the drive arm 15. Moreover, since the thickness of the dust layer 21 grows only up to about 0.1 ffil empirically, by setting the height of the protrusion 20 to about 0.1 ffil, the thickness of the first wedge plate 17 and the second wedge plate are finally
The wedge plates 19 can be brought into sliding contact surface to surface.
