              8月22日15时20分，安庆石化炼油一部催化装置双动滑阀自锁故障被成功排除、南北两组阀门信号偏差大的问题得解决，鸭嘴阀双动滑阀在操作室DCS上顺利投入自动控制。至此，该部“关键装置”的特殊阀门成功修复，确保了装置高负荷安稳生产。

        8月21日上午，催化装置班组盯表人员发现双动滑阀出现综合报警和南北两组信号偏差较大的现象，盯表人员立即将该阀门改至手动控制，同时联系仪表维修人员来现场检查、校正。由于双动滑阀是炼油一部乃至安庆石化重点监控的关键设备，低温阀门它是催化装置控制再生器压力至关重要的特殊阀门，若是出现故障，不仅影响到该装置反应—再生系统的平稳操作，而且会波及装置主要能量回收设备——烟机组的正常运行，排气阀以及整个装置的安稳生产。

        但由于双动滑阀精密度和灵敏度都非常高，因此处理眼镜阀 盲板阀消缺技术要求也特别高。加上双动滑阀位置处于30多米高的平台上，旁边还紧挨着粗大的高温烟气管道，恶劣的环境给现场作业人员带来了极大的挑战。 在30多个小时的修复处理过程中，催化装置操作人员积极配合仪表工，顶着烈日的炙烤和热浪的“熏陶”。将双动滑阀现场锁位、卸负荷、停油泵，改至手摇控制，室、内外人员紧密配合，进行一点一点地校正、调试。 为了降低双动滑阀油温高的问题，柱塞阀操作人员还及时将循环水由有压回水改至无压回水，消除了滑阀系统的报警因素，保证了该设备的正常运行。经过现场人员的共同努力，终于在双休日成功修复了“关键装置”的“特阀”。

At 3:20 p.m. on the August 22, Anqing Petrochemical refining a catalytic device self-locking double-acting slide valve failure was successfully removed, north and south groups Famen signal deviation was a big problem to solve, double-acting slide valve on the well in the operating room DCS input control. So far, the Department "critical device" special valve repair success, to ensure stable production of high load the device. August 21 morning team stare TableForged Steel Valves catalytic device found double-action slide valves are integrated alarm and two sets of signal deviations greater North-South phenomenon, stare table personnel immediately changed to manual control valves, and instrument maintenance personnel to contact on-site inspection, Filters calibration. As the double-action sliding valve is even Anqing Petrochemical refining a key focus of monitoring equipment, it is the catalytic cracking unit regenerator pressure control valve special importance, if the failure affects not only the response of the device - the smooth operation of regenerative system and will affect the API Cast Steel Valvesmain energy recovery equipment installation - the normal operation of tobacco unit, and the stable production of the device. However, double-acting slide valve precisionReducing Valves and sensitivity are very high, so deal with technical requirements for eliminating defects also particularly high. With double-acting slide valve position is 30 meters high platform next to the still next to a thick high temperature gas pipeline, poor environment for site work and posed a great challenge. More than 30 hours of repair in the treatment process, the catalytic device operators actively work with the instrument, Water power control valvesthe baked under the scorching sun and heat waves, "edification." Double-acting spool valve to the lock position the scene, dumping load, stop pump, change to hand control room, work closely with internal and external personnel to carry out little by little correction, debugging. After on-site personnel to work together, and finally succeeded in repairing the weekends "critical devices" in the "special valve."
