摘要： PROBLEM TO BE SOLVED: To enhance the stability of control level of a gate set just under the stream of a plurality of dividing wells provided in a channel and eliminate the leakage of a stored water. SOLUTION: This gate controls a float interlocking with a door body by a level detecting float. A water catch pipe 101 for carrying the upstream water is mounted on a float chamber 3, and the level detecting float and a valve element 12d for opening and closing the water catching pipe are suspended from each end part of a first wire rope 12b. On the other hand, a level correcting arm 13a is mounted so as to be interlocked with the rotation of the door body, a second wire rope 13b, f mounted on the level correcting arm is connected to the first wire rope 12b. The second wire rope is movable in the same direction as the valve element 12b, and a spring and delay device 13d are interposed in the middle part of the second wire rope. Thus, a time difference is caused between the opening and closing of the gate and the fluctuation of a set level, and level control can be surely performed. Further, a level regulating valve is closed, whereby the bypass route for the upstream water is interrupted.

摘要： PURPOSE:To inexpensively attain prevention of decomposition of agricultural products of a dryer for farm products. CONSTITUTION:A cooling dehumidifier 3 which is communicated with a joining chamber 6 connected to an air sending pipe 7 of a silo 8 and with an exhaust pipe 9 of the silo 8 or the atmosphere is installed and a vaporizer 2 for vaporing liquefied oxygen or nitrogen is laid in the cooling dehumidifier 3 to communicate a nozzle of an air ejector 4a connected to the vaporizer with the air sending pipe 7. The vaporizer cools air or a waste gas by vaporization of a refrigerant. A cold mixed gas obtained from mixing of the refrigerant and air or the waste gas is sent to the silo 8 so that decomposition of agricultural products can be prevented and activities of filamentous fungi to decompose farm products are suppressed by adjusting and setting concentrations of oxygen and nitrogen at a high values to surely prevent decomposition. Since the prevention of decomposition of agricultural products is attained by setting a device for preventing decomposition additionally based on existing facilities, the existing facilities are not required to be renewed and the cost of the whole device can be reduced.

摘要： PURPOSE:To ensure the safety of control of a gate in an emergency, to constantly keep the gate on standby, and to reduce the cost of the gate. CONSTITUTION:An automated emergency door shutting device has a reclining dam 7 provided in such a manner as to freely rotate with one end supported to an axis, a cylinder 8c provided diagonally behind the axially-supported portion of the reclining dam 7 in such a manner as to freely rotate with one end supported to an axis, an arm 8g for connecting the piston rod 8d of the cylinder 8c to the reclining dam 7, and a suction and exhaust system 10 for actuating a piston 8d inside the cylinder 8c, the place of installation of the cylinder 8c being separated from that of the suction and exhaust system 10 by lines 10h, 10g. When air is fed into the cylinder 8c the piston rod 8e expands and the reclining dam 7 is erected; when air is vented the reclining dam 7 is turned down. Also, remote control is simplified by extension of the lines 10h, 10g.

摘要： PURPOSE:To provide a storage quantity distributing gate having good efficiency of gate operation, which is adapted to store flowing water equally in plural gates extending over the whole area of a channel. CONSTITUTION:A door 3 is provided across a channel 2, a static water pool 7 and a float chamber 4 are disposed on the side of the channel 2, and a float 5 which interlocks with the door 3 and introducing water on the downstream from the door 3 into the interior thereof is floated in the float chamber 4. A water level detecting float 23 and a water level difference detecting float 16 for introducing water on the downstream from the door 3 into the interior thereof are floated in the static water pool 7. A rope 21 by which the water level difference detecting float 16 is suspended is fixed to a pin 44, and a push-up roller 26 is moved up and down by the float 5 and the water level detecting float 23. The actuation of the push-up roller 26 is converted to the rotary motion by a rack 39 and a gear 41, the pin 44 is turned by the rotary motion to equilibrate the water level difference detecting float 16, and a difference in water level between the right upstream and the right downstream of the gate 1 is adjusted by the water level difference detecting float 16. Thus, a water level difference of the right upstream between two points can be fixed.

摘要： PURPOSE:To make the passage of an opening of a valve smooth and maintain watertightness when the valve is opened. CONSTITUTION:In a valve 5 which is opened or closed by sliding a sleeve 10 to bring the forward end of the sleeve into or out of engagement with the side surface of a cone 11, a trumpet-mouth-shaped portion 10a is formed on the forward end of the sleeve and the cone is divided into a hammerless cap portion 12 having a slit 12 and a straightening portion 13 having a gradually expanding skirt shape through a joining surface 11a, wherein the surface 11a is made smaller than the inner diameter of the sleeve 10. At the beginning of opening the valve, a flow passage becomes narrow rapidly, however, water is discharged smoothly into a buffer pond 1 by means of the portion 10a and the portion 13, so that loss water head at the opening is made smaller. Further, when the valve 5 advances in an opening direction, gap interval becomes parallel and hence opening speed of the valve becomes slower. As a result, water hammer can be avoided, and since the clamping force for the portion 13 by the sleeve 10 is large, watertightness can be maintained.
