Radial gate


　　Radial gateis the part of the arc facing the water cylinder. The supporting hinge of the support arm is positioned at the center of the circle, and when the gate is opened and closed, the gate rotates around the supporting hinge. The arc-shaped gate is composed of three parts: the revolving door body, the buried component and the headstock device. The arc gate has no gate slot, less opening and closing force and good hydraulic condition. It is widely used as a gate for various types of waterways. Arc gate opening and closing force is small, the lifting point of the trajectory is arc, open top or wide width of the arc gate, more than two hanging points, hoist equipment used more than one machine layout. According to the structure of the building, opening and closing the form of radial gate is often used: hanging point in the front panel of the door leaf, the wire rope hoist or plate chain hoist; hoisting point in the beam after the door leaf panel or on the arm, the wire rope winch and hydraulic hoist. The cylinder block of the hydraulic gate of the radial gate is generally made to swing so as to make the layout compact and the weight of the equipment reduced.
　　classification
　　According to the depth above the gate, the water depth is divided into exposed and submerged type. The water level of the reservoir is no more than the top of the gate. It is called an open top arc gate (also called a curved gate). The reservoir water level is higher than the gate top. It is called submerged arc gate (also called deep hole arc gate or high pressure arc gate).
　　According to the force transmission arm into the form of inclined arm type and straight arm type. The former is used for wide, high and relatively large orifice. The latter is used for wide, high and relatively small orifices.
　　According to the form of the hinged shaft, they are divided into cylindrical hinge, conical hinge, spherical hinge and double cylindrical hinged arc gate.
　　According to the gate leaf structure, the main beam type and the main beam type arc gate and so on (back pressure called reverse arc gate).
