摘要
从设计和运行两方面探讨了热水供热系统的水击防护措施。设计中,管道坡度应平缓,确定合理的定压点压力,选用合适的管道阀门,选用动作灵敏的止回阀,在循环泵进出口之间设置带止回阀的旁通管。运行中,控制关闭阀门时间,采用合理的关闭阀门方式。
The protective measures against water hammer in hot-water heat-supply system are dis- cussed from aspects of design and operation. In the design, the pipeline slope should be gentle, the reasonable pressure is determined at pressurization points, the appropriate pipeline valve and the check valve acting quickly are selected, and a by-pass pipe with check valve is set between the inlet and outlet of circulating pump. In the operation, the valve closure time is controlled, and the reasonable mode of valve closure is adopted.
