指出在执行《自动喷水灭火系统设计规范》条文9.3.5和10.1.4条时，减压阀设置位置宜在环状管道的两侧单独设置,同时指出上述条文说明中的图式有不合理现象。 现行《自动喷水灭火系统设计规范》GB50084-2001(以下简称《喷规》)，在诸多方面发生了变化，相比原《喷规》来讲，更加完善合理。但一些新增条文在执行过程中还有待探讨，本文就《喷规》第9.3.5和10.1.4条中的用词和图式说明作出自己的看法，供同行商榷。 1、减压阀的设置探讨 《喷规》新增条文9.3.5条第三款为“当连接两个及以上报警阀组时，应设置备用减压阀”，条文说明示意见图1。条文9.3.5条中设备用减压阀的目的是：当一组减压阀检修或损坏时，另一组仍维持系统正常供水。从其设置目的来看，如果是连接减压阀的过滤器或减压阀组前后的管道损坏或检修时，就算是备用了减压。阀，整个系统还是要停止供水。从整个系统来讲，备用减压阀不是实现系统供水安全可靠的必要条件。 2、环状管网的设置探讨 《喷规》新增条文10.1.4条为：“当自动喷水灭火系统中设有两个及以上报警阀组时，报警阀组前宜设环状供水管道”，条文说明示意见图2。条文10.1.4条中设置环状供水管道的目的是：当环状管网一侧的管道、阀门或仪表检修时，另一侧仍能保持系统正常供水。从其设置的目的来看，对于两个以上报警阀组并联设置的自动喷水灭火系统，报警阀前应设置环状管道。因在火灾初期，自动喷水灭火系统的功效要优于消火栓，而消火栓在室内消防用水量大于15L／s时，要求室内管道至少应有两条进水管分别与室外环状管道的不同管段连接。所以从供水的安全可靠性来讲，两个及以上报警阀组并联设置的自动喷水灭火系统，报警阀设置环状管道非常必要。对于串联接人湿式系统的其它组件，虽设置了几组报警阀，但由于其共用配水干管，报警阀前则无须设置环状管道。 总之，报警阀前设置环状供水管道的系统，如须设置减压阀时，宜在环状管道的两侧单独设置，一般可不设备用减压阀。(图1中过滤器的布置位置及方向与图2中止回阀的位置均不合理，合理布置见图3)当然在管理条件较好，能够保证减压阀组定期轮换工作的情况下，也可设备用减压阀。需要指出的是不得绕减压阀设旁通道。 3、结论 总上所述，笔者认为《喷规》9.3.5条第三款与10.1.4条应做适当改动，改动后的条文可合并为“当自动喷水灭火系统中有两个及以上报警阀组并联设置时，报警阀组前应设环状供水管道；当需设减压阀时，宜在环状管道的两侧单独设置，有条件时可设备用减压阀。”

Pointed out that the implementation of "automatic sprinkler system design," the provisions of Article 9.3.5 and 10.1.4, the relief valve setting in the circular tube position should be set separately on both sides, noting that the provision in the schema are not in rational behavior. The existing "automatic sprinkler system design" GB50084-2001 (hereinafter referred to as "spray Regulation"), a change in many ways, compared to the original "jet rules" in terms of a more perfect and reasonable. However, some new provisions in the implementation process remains to be discussed, this article on "jet rules" section 9.3.5 and the wording of Article 10.1.4 and schematic description of his views, for peer discussion. 1, the setting of pressure reducing valve "Spray rules" new provisions for the third paragraph of Article 9.3.5 "when connecting two or more alarm valve, the valve should be set to standby," the provisions of note indicated in Figure 1. Provisions of Article 9.3.5 Pressure relief valves for the purpose of equipment: When a group of valve repair or damage, the other group remained normal supply system. From its set purpose, if the filter is connected valve or valve group before and after the repair pipeline damage or when, even spare the decompression. Valve, the entire system or to stop water supply. Terms of the whole system, spare valve system is not achieving the necessary conditions for safe and reliable water supply. 2, the settings of Pipe Network "Spray rules" for the new provisions of Article 10.1.4: "When the automatic sprinkler system with two or more alarm valve, alarm valve ring should be established before the water supply pipeline" provision in the hands shown in Figure 2 . Provisions of Article 10.1.4 The purpose of water supply pipes ring set is: when one side of the pipe for pipe systems, valves or instrumentation maintenance, the other side of the normal supply system can be maintained. Its setting purposes, the alarm valve for more than two parallel set of automatic sprinkler system, alarm valve should be set before the ring pipeline. Because of the fire early, the effectiveness of the sprinkler system is superior to fire hydrants, and fire hydrant indoors water than 15L / s, require at least two interior pipe inlet pipe separately with the different outdoor ring pipe connection. So from the safety and reliability of water supply in terms of two or more parallel set alarm valve sprinkler system, alarm valve set to ring pipeline is necessary. For the series of wet system access to other components, although several groups set alarm valves, but their share of water distribution mains, alarm valve set is not required before the pipeline ring. In short, the alarm set to ring the water supply pipe before the valve system, such as relief valve shall be provided when, in the ring should be set separately on both sides of the pipeline, generally from time to equipment valve. (Figure 1 Layout of the filter and the direction of valve position in Figure 2 are reasonable, rational arrangement of Figure 3) course management is better, to ensure the valve group work, the regular rotation, but also to equipment valve. Be noted that not located next to the channel around the valve. 3, Conclusion The total above, I believe that "spray rules" third paragraph of Article 9.3.5 and Article 10.1.4 shall make the appropriate changes, changes can be merged after the provision for "automatic sprinkler system when two or more alarm valve set parallel set, the alarm valve should be set before the ring of water supply pipeline; when required when the set valve, the ring should be set separately on both sides of the pipeline, valve equipment when conditions.
