WebA Ball valve is a quarter-turn rotary motion valve that uses a ball-shaped disk to stop or start the flow. It resembles a plug valve in many ways. When a port in the ball is in line, it allows flow, whereas when you rotate the valve 90 degrees, the solid part of the ball stop the flow. Most ball valves are quick-acting, requiring a 90° turn of ... Webthe gate arm, near the trunnion bearing, using strain gauges. One strain gauge is attached at the upper side of the gate arm, and one is attached at the lower side of the gate arm as indicated in Figure 2. Each strain gauge measures the surface mechanical stress in parallel to the main stress direction in the gate arm. Figure 3.
Radial gates consist of the following four parts: 1. The gate leaf assembly, including the curved skin plate, cross bracing or struts, supporting beams and girders, and rubber seals. 2. Arm assembly, including the arm columns, bracing, and hub. 3. Trunnion assembly, including a pin, busing, thrust washers, … See more In a radial gate, water pressure is transferred from the curved face to the radial gate arms which transfer the load to a common bearing on … See more Hydraulically, the gate is a sluice gate and should be designed as such.
