The paper considers that in the design of gas transmission pipeline, if block valves are laid out according to area classification and then to increase "bank block valves" on both sides of rivers,the quantity of block valves will be greatly increased.
在输气管道设计中,如果按地区等级设置截断阀之后再加设大型河流两侧的岸边截断阀,截断阀的数量将大大增加。
For the safety of gas transmission in long distance pipeline,the method regarding how to get the proper value of pressure drop rate for the fast block valve on pipeline is studied.
根据输气管道安全的需要 ,对干线快速截断阀压降速率设定值的确定方法进行了研究。
