Many industrial production equipment are skilled when they are overhauled. These are summarized by experienced teachers through continuous operation and test, which can not only reduce the risk of operation, but also reduce the energy consumption inside the equipment. It is a very needed way in many enterprises, How to better deal with the residual accidents when using pneumatic ball valves? For example, when using pneumatic ball valves, the sound of vibration is easy to occur.

Common faults of electric ball valve: typical faults of electric ball valve, safety valve, tension spring between valve stems and an action installed on the actuator in one of the directions of its door valve reciprocating to urge the door, which may be a closed body, the control fluid is applied to the piston in the dry actuator to overcome the tension spring force, and then kept open in other directions, Therefore, as a long-term maintenance under the control condition, when the structural valve is placed at a large depth and the body pressure is much lower than the surrounding sea pressure drop, the tension spring of the electric ball valve must be large, and the force to close the valve cannot meet the failed position of the mobile door due to the pressure effect of the body. May occur under extreme conditions. Then the planning of the actuator was reduced and the depth rating of the valve was increased. Troubleshooting: electric ball valve faults are included in this category. The valve body has a traditional valve that passes through the structure and intersects a cavity. The cavity is opened and closed between attitudes, and is responsible for moving the actuator between these positions. Since it is also in the case of this type of valve, the actuator consists of a bonnet mounted on the valve body and a stem connected to another valve.
