管网与喷嘴是气体灭火系统灭火剂输送、喷射的核心通道，管网密封失效泄漏、喷嘴堵塞堵塞偏移，是导致灭火浓度不达标、系统灭火失效的高频隐患。多数现场故障并非系统设备本体故障，而是管网运维、检测不到位引发的通道故障。依据GB25972-2024及建筑消防设施检测技术规程要求，管网与喷嘴检测需覆盖密封性、通畅性、安装合规性、工况适配性四大维度，全程量化检测、逐项排查。

管网密封性检测是重中之重，分为静态保压检测和节点精细化检漏两大模块。首先开展管网整体气密性试验，封堵管网末端喷嘴，通过专用试压设备对管网充压至设计工作压力，稳压24小时，核查压力压降值，规范允许压降不得超过设计压力的5%，无压力骤降、渗漏现象即为合格。针对高压管网、法兰连接处、螺纹接口、高压软管、单向阀、集流管等薄弱节点，采用高精度检漏仪或肥皂水涂刷法精细化检测，重点排查微渗漏隐患。长期运行的管网易出现接口密封垫老化、螺纹松动、软管龟裂等问题，此类微渗漏肉眼难以识别，会造成灭火剂缓慢损耗、压力持续下降，是日常巡检的盲区，必须通过专项检测彻底排查。

管网安装合规性与工况稳定性检测需同步开展。全程核查管网敷设坡度、支架间距、固定方式符合设计规范，管道无变形、弯折、下垂，高压软管无扭曲、拉伸、老化鼓包。管网穿越墙体、楼板的封堵措施完好，防火封堵材料密实无脱落，杜绝火灾烟气蔓延通道。同时核查管网泄压装置、安全阀门状态，泄压阀整定压力符合设计要求，动作灵敏可靠，杜绝管网超压爆裂风险。对于多防护区共用管网系统，逐一核查选择阀安装位置、启闭状态，阀门标识清晰，动作切换灵活，无卡顿、密封不严问题，确保不同防护区灭火工况独立可控。

喷嘴通畅性与喷射适配性检测直接决定灭火效果。拆除各防护区所有喷嘴，采用干燥压缩空气逐段吹扫管网，清除管内积尘、杂质、锈蚀碎屑，杜绝杂物堵塞喷嘴。核查喷嘴型号、孔径、安装位置、喷射角度完全符合设计方案，严禁私自更换喷嘴规格、改动安装位置。喷嘴外观无变形、破损、堵塞、积灰，防护网完好齐全，无异物遮挡。同时核对喷嘴布置密度、喷射覆盖范围，确保无灭火盲区，能够实现防护区全空间均匀喷射，快速达到灭火临界浓度。检测中发现堵塞喷嘴需彻底疏通，破损、变形喷嘴必须直接更换，杜绝带病投入使用。

针对老旧管网系统，需重点排查疲劳老化隐患，长期启停震动、环境温湿度变化易引发管网接口松动、金属疲劳，需缩短检测周期、强化复测力度。所有检测数据需完整记录，包含管网保压数据、节点检漏结果、喷嘴状态、整改明细，形成闭环检测档案。管网与喷嘴是系统的“血管”与“喷头”，通道通畅、密封完好，才能保障灭火剂快速、足额、精准喷射，从根本上保障气体灭火系统灭火效能达标。

泄压装置、安全阀门状态，泄压阀整定压力符合设计要求，动作灵敏可靠，杜绝管网超压爆裂风险。对于多防护区共用管网系统，逐一核查选择阀安装位置、启闭状态，阀门标识清晰，动作切换灵活，无卡顿、密封不严问题，确保不同防护区灭火工况独立可控。"}}},"align":"left","parent_id":"IvOidXy8roBlBzxsDi4ckVlEnyh","locked":false,"hidden":false,"author":"7581245381749509323"}},"SV7Ef2blkdGtUFcC4KfcRS1OnRd":{"id":"SV7Ef2blkdGtUFcC4KfcRS1OnRd","snapshot":{"comments":[],"locked":false,"author":"7581245381749509323","children":[],"text":{"apool":{"nextNum":2,"numToAttrib":{"0":["author","7581245381749509323"],"1":["ai-extra","{\"is_ai_gen\":true}"]}},"initialAttributedTexts":{"attribs":{"0":"*0*1+6n"},"text":{"0":"喷嘴通畅性与喷射适配性检测直接决定灭火效果。拆除各防护区所有喷嘴，采用干燥压缩空气逐段吹扫管网，清除管内积尘、杂质、锈蚀碎屑，杜绝杂物堵塞喷嘴。核查喷嘴型号、孔径、安装位置、喷射角度完全符合设计方案，严禁私自更换喷嘴规格、改动安装位置。喷嘴外观无变形、破损、堵塞、积灰，防护网完好齐全，无异物遮挡。同时核对喷嘴布置密度、喷射覆盖范围，确保无灭火盲区，能够实现防护区全空间均匀喷射，快速达到灭火临界浓度。检测中发现堵塞喷嘴需彻底疏通，破损、变形喷嘴必须直接更换，杜绝带病投入使用。"}}},"align":"left","type":"text","parent_id":"IvOidXy8roBlBzxsDi4ckVlEnyh","revisions":[],"hidden":false}},"Nvv8fIUsAd6X1VcfiTHcOaDknVv":{"id":"Nvv8fIUsAd6X1VcfiTHcOaDknVv","snapshot":{"text":{"initialAttributedTexts":{"text":{"0":"针对老旧管网系统，需重点排查疲劳老化隐患，长期启停震动、环境温湿度变化易引发管网接口松动、金属疲劳，需缩短检测周期、强化复测力度。所有检测数据需完整记录，包含管网保压数据、节点检漏结果、喷嘴状态、整改明细，形成闭环检测档案。管网与喷嘴是系统的“血管”与“喷头”，通道通畅、密封完好，才能保障灭火剂快速、足额、精准喷射，从根本上保障气体灭火系统灭火效能达标。"},"attribs":{"0":"*1*0+4y"}},"apool":{"numToAttrib":{"0":["author","7581245381749509323"],"1":["ai-extra","{\"is_ai_gen\":true}"]},"nextNum":2}},"align":"left","parent_id":"IvOidXy8roBlBzxsDi4ckVlEnyh","comments":[],"revisions":[],"locked":false,"hidden":false,"type":"text","author":"7581245381749509323","children":[]}},"IvOidXy8roBlBzxsDi4ckVlEnyh":{"id":"IvOidXy8roBlBzxsDi4ckVlEnyh","snapshot":{"text":{"apool":{"nextNum":2,"numToAttrib":{"0":["author","7581245381749509323"],"1":["ai-extra","{\"is_ai_gen\":true}"]}},"initialAttributedTexts":{"attribs":{"0":"*0*1+g"},"text":{"0":"8篇气体灭火系统专业检测技术推文"}}},"doc_info":{"option_modified":null,"editors":["7581245381749509323"],"options":["editors","edit_time"],"deleted_editors":null},"type":"page","comments":[],"locked":false,"children":["QtByfIkcudd3FpcpukycZcDzn1G","QTDPfvu3hdG2ircNxUxc6YXoncd","W9GrfKaHOdb6FocHHH6cO4oLn8d","Z8Ovf02UUdKTTScZ5eMc85Fjnog","OZtSflwYkdQFSac4tSMcLZXqnF4","Z1txfZ9xCdcAfOcST45c0eXrnUc","NH75fYLJvdxpDwcbapocOoabnNb","BDIZf3RsmdJAldckYDWc5gwQnuf","Ep3GfjOhld1jJncwxM5c4Wasnkc","Dpxbf7RpVdgymqciAW6cxx8Tn7b","SV7Ef2blkdGtUFcC4KfcRS1OnRd","Nvv8fIUsAd6X1VcfiTHcOaDknVv","UPUzfjI0Jd6CwGcqZfLcRaIqnvg","I8QBf7xMzdE98zcgaJEcqnW6nce","J8NrfwohRdeQaPcaijHcnIJDnZg","IUxJfBU17d2zkIcHmfKcIjbgnjb","Gy1xfw14XduDMkcIdyZcQo7JnH0","MgTofDiQ0dYRNpcEby1c5qbOnlc","BFSffIQmHd96yechQ51cv92TnZd","WGnBfGy3odJWZfcykjPcGXTGnLf","ApfrfMFkZd8vzRcTLmOcT7bRnkb","TnFQfyxUEdJ02Ic4Jk8cRnfqnvf","J89GfraHZdTrjtcFKRjcQdS4ngb","EaFrfiZhDdj6jtcpdHDcYvR5nhd","WDaqf7HUcdhvfUcvrDEcQvnEnze","RpbZfNWVSdAHFacZDnXcttPjnKd","CHEIfVhd0d7cfUcXNeSci0epnqh","Hu4BfCq0ydioq0c4gemc1Hixn8c","TnitfyycBdUK5EcxcIrcUopwnbh","FgLnfT4lydBSVPcXZgMcVfCzn7d","SuUcftcyOdIc7Qc7b4tczsjtn6d","UNJwfOnqGdc7gjcaBQWcAtwfnVd","Uo8Ff3witdHrewcLGVicJgwyn5f","RoiafsVfEdXgbmcpGutcGU5onag","Qzdtf6Llid1U7dco6OacueYknWf","Oujifis7EdkdoHcl2gTcJVE9nBc","Oz6efnDFKdaLCpcKJFfcTOmPnQh","HgKkfHMiudX4ktc9o6Vc40t7n9f","ZfWYfVkOHdeLLzcPYhCc7HKUncf","FR3wf2VwmdgsY5cT2cXche8Dn1d","S2VRfWKoQdTxgWcfzI9cjDnfn1e","GR23fZg3bdKGXVcj8GPcaWphnXd","PEc3fDkijduI8cc4pH7c3SnBnWe","LzA8fJEC6dCTpXcPL3ic2FDanRd","NNE9fGHsCdgOK7c3ozxc7wn9nof","LzuCfeSHndr76tci8P9ca3qEnsi","WsDofyAVGd4aLJcV4MBcNtNMnLf","WAbJfLnlZd1VRHcbZXZcj3o4nMg","Vv8YfCKYsd6rw7c7REHchf2wn2c"],"align":"","revision_container_id":"doxcnuB3ip9PXuBBQy5ithmevtd","status":{"streaming":{"enabled":false,"expired_at":"1782462383","source":1,"operator_id":"7581245381749509323","is_create_command":true}},"parent_id":"","revisions":[],"hidden":false,"author":"7581245381749509323"}}},"payloadMap":{"BDIZf3RsmdJAldckYDWc5gwQnuf":{"level":1},"Ep3GfjOhld1jJncwxM5c4Wasnkc":{"level":1},"Dpxbf7RpVdgymqciAW6cxx8Tn7b":{"level":1},"SV7Ef2blkdGtUFcC4KfcRS1OnRd":{"level":1},"Nvv8fIUsAd6X1VcfiTHcOaDknVv":{"level":1}},"extra":{"channel":"saas","pasteRandomId":"880900ca-87bb-4429-b994-4dbf4c1010d1","mention_page_title":{},"external_mention_url":{},"isEqualBlockSelection":true},"isKeepQuoteContainer":false,"selection":[{"id":9,"type":"text","selection":{"start":0,"end":180},"recordId":"BDIZf3RsmdJAldckYDWc5gwQnuf"},{"id":10,"type":"text","selection":{"start":0,"end":276},"recordId":"Ep3GfjOhld1jJncwxM5c4Wasnkc"},{"id":11,"type":"text","selection":{"start":0,"end":237},"recordId":"Dpxbf7RpVdgymqciAW6cxx8Tn7b"},{"id":12,"type":"text","selection":{"start":0,"end":239},"recordId":"SV7Ef2blkdGtUFcC4KfcRS1OnRd"},{"id":13,"type":"text","selection":{"start":0,"end":178},"recordId":"Nvv8fIUsAd6X1VcfiTHcOaDknVv"}],"pasteFlag":"28ba47ba-7f5f-4d6d-a215-72511c7410bc"}" data-lark-record-format="docx/record" class="lark-record-clipboard">
