早期損傷が発生していた。 The shape of the packing 3 includes, in addition to the hollow type, the solid type, the double chevron type, and the one with a round top (contact surface).
Various cross-sectional shapes are used, such as those with flat tops, but in all shapes, the compressive force is perpendicular to the pressure-receiving surface, and the compressive force is inclined to the pressure-receiving surface. In this case, the packing 3 is subjected to an uneven load, causing large asymmetrical deformation in the cross-sectional shape and causing damage. That is, when the packing 3 is compressed by δd by the compressive force in the direction of arrow A, the hollow packing as shown in FIG. Watertightness is maintained due to the repulsive force of , but the amount of deformation of the portion B becomes larger than that of the portion C on the opposite side.
In addition, since there is no deformation gap in a solid type packing without a hollow part, a large compression force is required to obtain the amount of compression required for watertightness, and early damage occurs due to fatigue of the rubber.

である。 This invention prevents early damage to the seal by uniformly distributing the compressive force to the seal when the pressure-receiving surface of the seal is inclined with respect to the compression direction. The opening has a concave slope around an opening located underwater, such as a bottom valve of a dumping ship, so that the opening is at the center, and an inclined surface substantially parallel to each of the above-mentioned inclined surfaces. A hollow part is formed between the opening and closing member capable of closing the opening, the cross-sectional shape is wavy, the convex part faces the opening and closing member, and the inclined part surrounding the opening surrounds the opening. In the disposed water stopper gasket, a notch having a substantially triangular cross section is provided around the entire circumference of the top portion of the water stopper gasket that contacts the opening/closing member on the opening side, and The gist of the water stopper is a water stopper, characterized in that a notch with a substantially triangular cross section connected to the hollow part is provided around the entire circumference on the hollow part side of the bottom on the opening side that comes into contact with the catch seat. It is.

状の切欠部１９が全周に亘つて形成されている。 In Figures 2 to 4, the seal of a seal receiving seat 10 is inclined concavely around an opening located in the water, such as the seal of a water gate or the bottom valve of a mud dumping ship, so that the opening is at the center. Mounting surface 11
The bottom part 13 of the packing 12 having a corrugated cross-sectional shape is in contact with the bottom 13 of the packing 12, and the bolt 15 is inserted into the bolt hole 14 drilled on both sides of the packing 12.
5.Put the packing 12 through the packing fitting 16
is attached to the gasket attachment surface 11 to form a hollow portion. The packing 12 is arranged so as to surround the opening. Each of the bottom part 13 and top part 17 of the packing 12 has a fourth
As is clear from the figure, a notch 18 that is continuous with the hollow part and has a substantially triangular cross section is formed on the hollow part side of the bottom part 13 on the opening side, and that
A notch 19 having a substantially triangular cross section is formed around the entire circumference at the frontmost portion of the top portion 17 on the side of the opening.

密に保たれて閉じた状態になるようにしてある。 An opening/closing member 20 such as a door plate having a sloped structure is formed with a packing contact surface 21 that is inclined parallel to the packing mounting surface 11, and the opening/closing member 20 is connected to a retracting rod 22 (see Fig. 2). It is pulled and moves in the direction of arrow A, and the packing contact surface 21 touches the packing 12.
When the gasket 12 is compressed by contacting the top 17 of the gasket, the space between the gasket seat 10 and the opening/closing member 20 is kept watertight and closed.

よい。 When the packing 12 begins to be compressed by the retraction of the opening/closing member 20, the compressive force in the A direction acts from the top portion 17 that contacts the opening/closing member 20, and as shown in FIG. D
Concentrate on that part. As the amount of compression increases, the contact surface between the packing 12 and the opening/closing member 20 expands to the notch 19, and the portion E of the packing 12 also deforms, and the deformation of the E portion is absorbed by the notch 18. As a result, the entire packing 12 is deformed into the shape shown by the two-dot chain line in FIG. 5, and the cross-sectional shape of the packing can maintain uniform deformation during compression. Note that the shape of the cutout portion may be close to a triangular shape, or may be a crescent shape.
本考案は、以上説明したように、パツキンが斜

圧縮時にパツキン全体として均一な変形となり、
圧縮力の偏荷重が軽減されるため、高い水密性の
維持とパツキンの疲労による経年劣化の防止に大
きな効果がある。 As explained above, even when the packing is subjected to compressive force in an oblique direction, the present invention provides a cross-sectional view of the bottom and top of the packing at the frontmost portions in the compression direction, that is, on the side close to the opening to be sealed. Since the triangular notch is formed, the entire packing deforms uniformly when the packing is compressed.
Since the unbalanced compressive force is reduced, it is highly effective in maintaining high watertightness and preventing aging deterioration due to packing fatigue.
