0. Conventional technology Conventionally, when repairing or replacing a water gate closing valve with a new one due to malfunction, failure, or other performance deterioration,
Before replacing the valve, the inlet of the water gate must be closed off to stop the flow of water to the valve, but in dams, etc., the only way to close the inlet is to have a worker go underwater and do the blocking work. The reality is that there is no suitable means for repairing the valve, and not only is the underwater work itself extremely difficult, but it becomes even more difficult when problems with water depth, sedimentation, sinking wood, and other obstacles to the work come together. In some cases, replacement was impossible.

In this case, the pedestal means by the pedestal 41 described above differs depending on the work place and the like. When the stop valve device 2B is completely fixed, the bolt 30 of the connecting portion 29 between the valve body 1 and the iron pipe 19 is removed as shown in FIG. Thereby, the valve body 1, the single pipe 2, the stop valve device 14, etc. are integrally moved to the downstream side, and the safety stopper 31 is attached to the flange of the connecting portion 29 on the side of the iron pipe 19 in that state. Thereafter, the pedestal 41 is removed and the tension rod 23 is separated from the plug rod 22 using the rod joint 20. As a result, as shown in FIG. 5, with the stop valve device 28 inserted and fixed inside the iron pipe 19, the other parts are separated and the removal work is completed.
