Explosion-proof electric valve is composed of two parts, namely valve and electric device, which are widely used in some automated pipeline systems. Because the two parts that make up an explosion-proof electric valve have different functions, they have an effective guarantee in terms of safety.
The structure of the explosion-proof electric valve part is relatively simple, while the structure of the electric device is more complicated. In addition to the mechanical transmission part, the valve electric device also has an electric drag part, a stroke control mechanism, a valve position indicating mechanism, a valve position signal feedback mechanism, and a torque control mechanism.
Therefore, in practical applications, the problems of explosion-proof electric valves generally occur on their electric devices, and these problems often affect the normal use of users and even cause the entire pipeline system to fail.
So what are the factors that affect the failure of explosion-proof electric valves?
There are many factors that cause problems with electric valves, mainly in product selection, complete sets of valves and electric devices, and manufacturing of valves and electric devices. These should be paid attention to. It is particularly important to note that China's current industry standards for explosion-proof electric valves,
Because it is a valve composed of two parts, this makes the electric valve insufficient in terms of complete set and acceptance. Therefore, reflecting the industry advantages in this area, the corresponding explosion-proof electric valve technical standards must be worked out as soon as possible according to the actual situation.
