南水北调中线工程PCCP及暗涵输水系统空气阀型式研究
Study on type of air valve for PCCP pipeline and buried culvert of water conveyance system for Mid-route of South-to-North Water Transfer Project
摘要
Abstract
For the Huinanzhuang to Darting Section of the Mid-route of the South-to-North Water Transfer Project, two parallel lines of PCCP pipelines with the diameter of 4m are adopted; which is a long-distance water conveyance system built with large diameter pipelines. The operation condition for the system is complicated with larger range of pressure change, for which the variety and characteristics of the destructive accident of the large long-distance pressure water conveyance pipeline caused by water hammer must be fully considered. Therefore, the analysis and demonstration are made herein on the type and layout of the air valves for the pipeline based on the characteristics of the project, so as to ensure the safety and reliability of the pressure water conveyance system and reduce the costs for both the maintenance and the operation as well关键词
