摘要
对重力有压输水系统的水锤特点进行了分析,指出末端关阀水锤是影响系统安全运行的主要问题。根据水锤基本理论,结合工程实例,对重力有压输水系统的末端关阀水锤进行了计算分析。在介绍减压恒压阀工作原理的基础上,进行了减压恒压阀水锤防护效果的预测,并对其影响因素进行了分析。最后,针对工程特点,提出了相应的水锤防护措施。
The characteristic of water-hammer in the gravity pressured water-delivery system is analyzed in this paper. It is indicated that the end valve-closure water hammer is the main problem which influencing the system safety. According to the basic theory of water hammer, combined with an example, the end valve-closUre water hammer in the gravity pressured water-delivery system is calculated. Moreover, based on the introduction of the work principle of pressure-reducing and constant pressure valve, its prevention effect is predicted and the influencing factors are analyzed. In the end, according to the project characteristic, the water-hammer prevention measures are put forward.
