摘要:
针对外资厂房消防供水系统设计既要满足国内规范要求又要符合美国消防协会规范的要求，以某外资汽车零部件新建工厂的消防供水系统的设计、安装、检查和测试为例，从消防泵房建造和消防泵的选型、消防泵吸水侧和出水侧所必须安装的管道配件以及消防泵的控制等方面分别对比分析了中美规范上的差异。强调了消防泵吸水侧和出水侧上压力表、异径管、止回阀和控制阀门的正确选型和安装位置，对比后借鉴了美国消防协会标准NFPA 20对供水系统上泄压阀和流量计的设计和安装要求，补充了NFPA 20上独有的自动循环阀及压力传感管的设计与安装，可提高消防供水的可靠性。
Abstract:
The design, installation, inspection and testing of fire water supply system in a foreign founded auto parts factory was introduced in this paper based on the requirements of both Chinese codes and National Fire Protection Association (NFPA) standards. The differences on fire water supply system between the Chinese codes and NFPA standards were compared and studied from the following aspects: construction of fire pump house, selection of fire pumps, the installation of fittings on the suction & outlet section and the control of fire pumps. The selection and position of pressure gauges, reducing pipe, check valve and control valves on suction and outlet side of fire pump were emphasized. The design and installation of main relief valve and flow meter in NFPA 20 were adopted by comparison. The unique design and installation of circulation relief valve and pressure sensing lines in NFPA 20 were supplemented. The purpose of all the recommendations was to improve the reliability of fire water supply system reasonably.
