Abstract
PURPOSE: To unnecessitate a mechanical lock mechanism in a high-pressure bonnet type gate by utilizing pushing-up force by high-pressure water inside a water conveyance path in order to keep the gate open.
CONSTITUTION: When pulling up a door 1 into a bonnet 5 by means of an opening device 3, the door 1 comes into contact with a stopper 11 provided to the upper part of the inside of the bonnet 5, whereby sealing up between the door 1 and the inner wall of the bonnet 5 by a water-tight sealing member 1b surrounding the lower periphery of the door 1. Thus, the door 1 can be kept open by means of high-pressure water inside a water conveyance path 2 by releasing the water pressure confined in the bonnet 5 by the water-tight sealing member 1b by opening a valve 13 immediately after opening the gate.
