第10题
清管器发送过程Pig delivery process: 1)关闭发送筒隔断阀门和平衡阀门Close the transfer cartridge partition valve and balance valve; 2)打开放空阀,卸掉发送筒中的压力,在发送筒中压力未达到大气压力前,不能急于打开盲板Open the vent valve and remove the pressure in the sending cylinder. Before the pressure in the sending cylinder reaches the atmospheric pressure, the blind plate cannot be opened in a hurry; 3)打开盲板,放入清管器,直到清管器到达发送筒颈缩管处,并在该处紧紧地贴合Open the blind plate and place in the pig until the pig reaches the delivery cylinder neck and fits tightly; 4)关闭盲板Close the blind plate; 5)轻微地打开平衡阀排出发送筒中的空气Slightly open the balance valve to expel air from the sending cylinder; 6)关闭放空阀并慢慢使发送筒中的压力增加到管线压力Close the vent valve and slowly increase the pressure in the delivery cylinder to line pressure; 7)关闭平衡阀,若没有关闭平衡阀就打开清管器发送筒的隔断阀门时,可能会损坏清管器Close the balancing valve and may damage the pig by opening the partition valve in the pig delivery barrel without closing the balancing valve; 8)打开清管器发送筒隔断阀门Open the pig delivery cylinder partition valve; 9)打开平衡阀,关小线路主阀,使清管器通过发送筒Open the balancing valve and turn down the line main valve so that the pig passes through the sending cylinder; 10)打开线路主阀Open line main valve; 11)关闭发送筒隔断阀门和旁通平衡阀Close the delivery cartridge partition valve and bypass balancing valve; 12)放空发球筒。Empty the tee.
