Recently, Zhejiang Lianda Valve Co., Ltd. came to the Electrometer center to carry out technical exchanges in terms of the working principle, structural characteristics, corrosion prevention and leakage prevention and optimization measures of gate valves and ball valves. Electrometer Center skilled personnel, division of labor personnel and youth League branch actively participated in exchange and learning.

The two sides discussed the impact of the production conditions on the on-site valves, such as erosion, cavitation and leakage, as well as the corresponding improvement measures, and combined with the current situation of external leakage treatment of some valves in the ane plant to treat the symptoms rather than the root cause, and the LDAR test seal is not up to standard, proposed to replace the new graphite sealing ring packing or adopt the disc spring loading design at the packing place to ensure the long-term effective sealing of the valve. Achieve the goal of no leakage of the device.

At the same time, the two sides also discussed the relevant matters for attention such as changing the pneumatic valve of the 7401 tank farm and increasing the actuator, and exchanged details such as the use, optimization, and follow-up maintenance of the ball valve and butterfly valve.
