               8月10日，西二线西段三号阀室引压管改造工程顺利竣工。 8月7日，西二线西段三号阀室引压管改造工程拉开序幕，闸阀施工作业地点为气液联动阀两侧阀室放空管DN400管径，动火等级为一级。闸阀改造工程由管道局维抢修分公司承担。 本次施工的主要环节是带压封堵，截止阀封堵后的泄漏程度直接影响到整个施工过程。

        开孔机在液压油动机的作用下，以每分钟12圈的速度匀速向里推进，蝶阀整个开孔过程需要近5个小时。封堵工通过观察标尺来确定盘刀的进刀尺寸。 据测算，作业过程中封堵效果比较理想，止回阀 在进行放空和氮气置换后，管工与焊工相互配合完成引压管的切割和大小头焊接。在拆除开孔机时，开孔机中心轴自动与塞柄脱离，开孔机完全退出后，安装封堵盘，检漏完成后，整个带压封堵引压管改造工程结束。

        August 10, western part of the 3rd West second-line joining pipe valve room renovation project was completed. August 7th, West, western part of the 3rd second-line joining pipe valve room renovation project kicked off, construction sites on both sides of the valve chamber Pneumatic valve DN400Gate Valves diameter vent pipe, hot work grade level. Dimensional reconstruction project by the Bureau of repair pipeline branch to bear. The main part of this construction Butterfly Valvesis under pressure sealing, and plugging the leakage after the extent of direct impact to the entire construction process. Opening machine in the hydraulic oil under the influence of motivation, to 12 cycles Ball Valvesper minute in advance to the uniform rate, the opening process takes nearly 5 hours. Sealing work disk by observing the scale to determine the size of a knife into the knife. It is estimated that operatingGlobe Valves results will be ideal blocking the process of carrying out short sales and nitrogen replacement, the foreman and the welders with each other to complete the cutting and joining pipe welding head size.Check Valves Hole in the demolition machine, automatically opening machine central axis of the handle from the plug, completely out of opening machine, the installation of closure plate, leak detection is complete, the entire block with a pressure of the end of joining pipe renovation project.
