| Abstract: | A variety of pressure reducing valve programs were made to analyse the multi-level decompression taking a gravity flow for long distance distribution pipeline engineering in northwest of China as an example. The results showed that the decompression constant pressure valve and surge shaft set on the long distance and high drop gravity distribution pipeline could effectively eliminate the surplus water head and ensure the safe operation of pipeline. |
