摘要： PROBLEM TO BE SOLVED: To minimize an extrusion pressure by forming a presser metal fitting on the atmospheric pressure side more thickly than a presser metal fitting on the hydraulic pressure side. SOLUTION: A presser metal fitting 6 on the atmospheric pressure side is formed more thickly than a presser metal fitting 5 on the hydraulic pressure side while a clearance S2 on the atmospheric pressure side is made smaller than a clearance S1 on the hydraulic pressure side. In the case when a sluice gate door 3 is closed, the sluice gate door 3 is slidingly closed while the head of water stop rubber 7 projected by the hydraulic pressure on a rear side is being pushed transversely. The head of the rubber in the early stage is separated from the sluice gate door 3 but when the sluice gate door 3 comes in contact with the head of the door 3 of the sluice gate later, a hydraulic pressure is loaded transversely on the head of the rubber, thereby producing the falling down of the head of the rubber on the atmospheric side. The root of the head of the rubber is swollen to the atmospheric side by this falling down of the head. Since the presser metal fitting 6 on the atmospheric pressure side supports this swollen area, the amount of the falling down of the water stop rubber 7 is relieved. Therefore, the water stop rubber 7 when closing the door 3 of the sluice gate is not easily sandwiched with the door 3 of the sluice gate and the presser metal fitting, thereby extending the service life of the water stop rubber.

摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of vibration of overflow water film and low frequency noise induced by the vibration without adopting a member for blocking the flow of the overflow water. SOLUTION: This is an overflow type gate 11 with which an overflow water film 14 is formed from an overflow current and dropped from an upper end portion 13 of a gate 12 to be opened or closed. In this case, water 21 is jetted toward an overflow water film 14 to be dropped and the overflow water film 14 is subdivided in the width direction of the gate 12 thereby prohibiting the formation of a large area of the overflow water film 14, therefore the vibration of overflow film and the occurrence of low frequency noise induced by the overflow film can be prevented without using members for blocking the flow of the overflow water.

摘要： PROBLEM TO BE SOLVED: To provide a sealing member which can generate a large contact pressure using a less pressing force without risk of forming a gap. SOLUTION: When this sealing member concerned is used as a side seal for a rotary valve, the side seal 3 is made from an elastic material such as resin or rubber in a ring form having an angular section and has a seal surface 3a such that the part of the outside surface nearer the inside in axial direction of a rotor 12 is inclined so that the wall thickness declines toward the inside, and the inclination angle θ0 of the seal surface 3a is set so as to be slightly smaller than the inclination angle θ1 of the interior wall surface 11a of a liner 11. Thereby the wall thickness to be crushed through elastic deformation is made greater in a position nearer the innermost so that it is possible to stand a peak of contact pressure in the inner portion of the seal surface 3a.

摘要： PURPOSE: To reduce the deformation amount of a water-tight rubber and improve maintainability of a water-tight joint section by providing a plurality of coil springs along a front end face and a rear end face of a double shell and preventing external force other than force for maintaining water-tightness from acting on the water-tight rubber. CONSTITUTION: When a case is submerged and excessive compression force 7 acts on a double shell 01a due to earthquake, a coil spring 6 supports it. Accordingly, a water-tight rubber 3 which is sandwiched between an overhanging plate 1 for mounting and an overhanging plate 5 for compression to stop water receives water pressure based on water depth at the installation place and is merely deformed slightly. Moreover, since a pleated steel plate 07 supports shearing force of the double shell 01a in the vertical direction and the forward and backward directions, large compression force does not act on the water-tight rubber 3. By the way, if water depth of the water-tight rubber 3 is 25 meters, water pressure which acts on it is about 2.5kgf/cm . Furthermore, when excessive tensile force 8 acts due to earthquake at the time of the construction of the submerged case, the coil spring 6 supports it. Accordingly, the water-tight rubber 3 receives water pressure based on water depth at the installation place and is merely deformed slightly. As for the other circumstances, it is the same as the above.
