          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，双动滑阀在操作室DCS上顺利投入自动控制。针型阀至此，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，同时调节阀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，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，呼吸阀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，以及整个装置的安稳生产。 为了降低双动滑阀油温高的问题，锻钢阀门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，减压阀终于在双休日成功修复了“关键装置”的“特阀”。 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。

           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, the valve signal deviation of two major north-south issue was resolved, double-acting slide valve in the operating room on the smooth DCS input control. So far, the Department "critical device" special valve repair success, to ensure stable production of high load theBall Valves device. August 21 morning team stare Table catalytic device found double-action slide valves are integrated alarm and Gate Valves deviation of the larger South-North phenomenon of two signals, keep an eye on the table staff to immediately change the manual control valves, and instrument maintenance personnel to contact on-site inspection, calibration. As the double-acting slide valve is the focus of Anqing Petrochemical refineries and even control a key equipment, which is the catalytic cracking unit regeneratorButterfly Valves 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 main energy recovery equipmentCheck Valves installation - the normal operation of tobacco unit, and the stable production of the device. Double-acting spool valve to reduce the problem of high temperature, the operator will also Ji Shi Xun Huan water by a pressure change to non-pressure Huishui backwater, eliminating the factors slide valve alarm system to ensure the normal operation of the device. Through the joint efforts of field personnel, and finally succeeded in repairing the weekends "critical device" of "special valve." More than 30 hours of repair in the Plug Valvestreatment process, the catalytic device operators actively work with the instrument, the baked under the scorching sun and heat waves, "edification." The double-acting slide valve on-site lock-bit, dumping load, stop pump, change to hand control room, work closely with internal and external personnel to carry out little by little correction, debugging.
