Explosion-proof electric valve is a very important kind of pipeline equipment in the development of China. Its structure is simple and its service life is longer than that of ordinary valves. In addition, explosion-proof electric valves have some well-known advantages, such as low explosion-proof costs, high safety, and corrosion resistance.
However, explosion-proof electric valves seem to be indestructible in some applications. The customer neglected to maintain it, and the sturdy valve will leak over time. This is not a valve design problem, but a problem that most valves have to face. Accidents caused by leakage of explosion-proof electric valves range from property damage to serious injuries. Therefore, in order to prevent this from happening, it is necessary to conduct a comprehensive inspection of the valve on a regular basis.
Among the two key valves and electric actuators to be inspected, maintenance personnel must take them seriously. After all, repairing valves is of great significance to safety. Some high-quality explosion-proof electric valves also often have leakage problems. Excluding valve design and structural problems, it may also be because the pressure is too high, or the service life is too long, so it is very important to look at the inspection and maintenance of explosion-proof electric valves. of.
