The valve mechanical product commonality

Valve is a kind of general machinery products, many varieties, wide application range, valve in the whole working unit and system plays a vital role. The valve in the important system with high reliability are put forward on the valve of the requirements of the corresponding reliability research is more and more important. Valve failure mechanism of theory research, valve reliability test and evaluation methods of the establishment of a reliability database of research and the valve is the valve of reliability research key content. Because the valve is versatile, so it is also a big role. People tend to focus on the main machinery and equipment, has neglected the valve. Valve electric actuator faults is a complex structure, use more difficult in damp places, when used in explosive medium, need to adopt and isolation measures. When the valve is rev torque is larger, can through the gear or worm gear drive, to achieve the purpose of ellipsis. Gear transmission points straight tooth cylindrical gear and taper gear transmission.
