警示！消防閥選錯(cuò)=火災(zāi)隱患，川消教你3分鐘分清防火閥、排煙閥、排煙防火閥
Warning! Wrong selection of fire damper=fire hazard, Sichuan Consumer Education teaches you to distinguish between fire damper, smoke exhaust damper, and smoke exhaust fire damper in 3 minutes
消防閥門(mén)是建筑消防系統(tǒng)的“咽喉”，防火閥、排煙閥、排煙防火閥的選型與區(qū)分，直接關(guān)系到火災(zāi)發(fā)生時(shí)的排煙控火效果，更是建筑消防安全的關(guān)鍵防線。據(jù)消防行業(yè)數(shù)據(jù)顯示，37%的建筑消防隱患源于消防閥選型錯(cuò)誤或安裝不當(dāng)，其中因混淆三類(lèi)閥門(mén)導(dǎo)致的火災(zāi)蔓延事故占比達(dá)29%，河北某養(yǎng)老公寓火災(zāi)中，就因閥門(mén)使用不當(dāng)導(dǎo)致噴淋系統(tǒng)失效，造成嚴(yán)重后果。作為深耕消防領(lǐng)域60余年的龍頭企業(yè)，川消（四川川消消防車(chē)輛制造有限公司）依托深厚技術(shù)沉淀，結(jié)合國(guó)標(biāo)規(guī)范，詳解三類(lèi)消防閥的核心區(qū)別與選型要點(diǎn)，幫工程從業(yè)者、物業(yè)管理人員避開(kāi)隱患，筑牢消防安全防線。
Fire valves are the "throat" of building fire protection systems. The selection and differentiation of fire dampers, smoke exhaust valves, and smoke exhaust fire dampers directly affect the smoke exhaust and fire control effect in the event of a fire, and are also the key defense line for building fire safety. According to data from the fire protection industry, 37% of building fire hazards are caused by incorrect selection or improper installation of fire valves. Among them, fire spread accidents caused by confusion of three types of valves account for 29%. In a fire in a nursing home in Hebei, the sprinkler system failed due to improper use of valves, resulting in serious consequences. As a leading enterprise with over 60 years of experience in the field of fire protection, Chuanxiao (Sichuan Chuanxiao Fire Fighting Vehicle Manufacturing Co., Ltd.) relies on profound technical expertise and combines it with national standards to explain the core differences and selection points of three types of fire valves, helping engineering practitioners and property management personnel avoid hidden dangers and build a strong fire safety defense line.
川消作為原公安部部屬企業(yè)改制轉(zhuǎn)型的合資企業(yè)，是國(guó)家專(zhuān)精特新“小巨人”企業(yè)，參與多項(xiàng)消防行業(yè)標(biāo)準(zhǔn)編制，其生產(chǎn)的消防閥門(mén)嚴(yán)格遵循GB15930-2007規(guī)范，涵蓋防火閥、排煙閥、排煙防火閥等全品類(lèi)，憑借嚴(yán)苛的品質(zhì)管控，成為各類(lèi)建筑消防系統(tǒng)的優(yōu)選品牌。很多從業(yè)者混淆三類(lèi)消防閥，核心是未抓住“動(dòng)作溫度、安裝位置、核心功能”三大關(guān)鍵，川消結(jié)合多年實(shí)戰(zhàn)經(jīng)驗(yàn)，用通俗且專(zhuān)業(yè)的方式，拆解三類(lèi)閥門(mén)的核心差異，避開(kāi)選型誤區(qū)。
As a joint venture enterprise restructured and transformed from a former subordinate enterprise of the Ministry of Public Security, Chuanxiao is a national specialized and innovative "little giant" enterprise that has participated in the formulation of multiple fire industry standards. Its production of fire valves strictly follows the GB15930-2007 standard, covering all categories such as fire dampers, smoke exhaust valves, and smoke exhaust fire dampers. With strict quality control, it has become the preferred brand for various building fire protection systems. Many practitioners confuse the three types of fire valves, with the core being the failure to grasp the three key factors of "operating temperature, installation position, and core function". Based on years of practical experience, Chuanxiao uses a simple and professional approach to dismantle the core differences of the three types of valves and avoid selection errors.
首先是防火閥（國(guó)標(biāo)標(biāo)記FHF），川消防火閥核心適配通風(fēng)、部分防煙系統(tǒng)，核心作用是阻斷火災(zāi)初期的煙氣蔓延，其動(dòng)作溫度分兩種場(chǎng)景：常規(guī)區(qū)域安裝的防火閥，動(dòng)作溫度為70℃，當(dāng)環(huán)境溫度達(dá)到70℃時(shí)自動(dòng)關(guān)閉，切斷煙氣流通；而安裝在廚房附近等高溫區(qū)域的川消防火閥，動(dòng)作溫度升級(jí)為150℃，適配廚房高溫環(huán)境，避免誤觸發(fā)。川消防火閥采用優(yōu)質(zhì)密封結(jié)構(gòu)，關(guān)閉后密封性能達(dá)標(biāo)，有效阻斷煙氣擴(kuò)散，同時(shí)可手動(dòng)復(fù)位，適配各類(lèi)民用、工業(yè)建筑的通風(fēng)系統(tǒng)。
Firstly, there is the fire damper (marked as FHF in the national standard). The core of the Sichuan fire damper is adapted to ventilation and some smoke prevention systems. Its core function is to block the spread of smoke in the early stages of a fire. Its operating temperature is divided into two scenarios: the fire damper installed in a conventional area has an operating temperature of 70 ℃, and it automatically closes when the ambient temperature reaches 70 ℃, cutting off the flow of smoke; The Sichuan fire control valve installed near the kitchen and other high-temperature areas has an upgraded operating temperature of 150 ℃, which is suitable for the high-temperature environment of the kitchen and avoids accidental triggering. The Sichuan Fire Control Valve adopts a high-quality sealing structure, and its sealing performance meets the standard after closing, effectively blocking the diffusion of smoke. At the same time, it can be manually reset and is suitable for ventilation systems in various civil and industrial buildings.
其次是排煙閥（國(guó)標(biāo)標(biāo)記PYF），與防火閥的核心區(qū)別的是，川消排煙閥自帶專(zhuān)用執(zhí)行機(jī)構(gòu)，核心功能是排出火災(zāi)產(chǎn)生的煙氣，而非阻斷煙氣。其安裝位置固定，主要位于機(jī)械排煙口內(nèi)部，平時(shí)處于關(guān)閉狀態(tài)，火災(zāi)發(fā)生時(shí)，可通過(guò)電控、手動(dòng)方式開(kāi)啟，快速排出區(qū)域內(nèi)煙氣，為人員疏散爭(zhēng)取時(shí)間。川消排煙閥配備位置信號(hào)反饋功能，可實(shí)時(shí)反饋閥門(mén)開(kāi)啟狀態(tài)，便于消防控制中心精準(zhǔn)管控，避免因閥門(mén)故障影響排煙效果。
Next is the smoke exhaust valve (marked PYF according to the national standard). The core difference from the fire damper is that the Chuanxiao smoke exhaust valve comes with a dedicated actuator, and its core function is to exhaust the smoke generated by a fire, rather than blocking the smoke. Its installation position is fixed, mainly located inside the mechanical smoke exhaust outlet, and it is usually in a closed state. In the event of a fire, it can be opened through electronic control or manual means to quickly exhaust the smoke in the area and buy time for personnel evacuation. The Chuanxiao smoke exhaust valve is equipped with a position signal feedback function, which can provide real-time feedback on the valve opening status, facilitating precise control by the fire control center and avoiding the impact of valve failure on smoke exhaust efficiency.
最后是排煙防火閥（國(guó)標(biāo)標(biāo)記PFHF），作為排煙系統(tǒng)的“終極防線”，川消排煙防火閥主要安裝在排煙系統(tǒng)、排煙風(fēng)機(jī)附近及防煙分區(qū)分隔處，兼具排煙與防火雙重功能。其核心動(dòng)作溫度為280℃，這是煙氣達(dá)到危險(xiǎn)溫度的臨界值，當(dāng)管道內(nèi)煙氣溫度升至280℃時(shí)，閥門(mén)自動(dòng)關(guān)閉，防止高溫?zé)煔饴又疗渌麉^(qū)域。更關(guān)鍵的是，安裝在排煙風(fēng)機(jī)附近的川消排煙防火閥，具備連鎖停機(jī)功能，閥門(mén)關(guān)閉后可自動(dòng)觸發(fā)風(fēng)機(jī)停止運(yùn)行，避免風(fēng)機(jī)吸入高溫?zé)煔鈱?dǎo)致?lián)p壞，降低火災(zāi)二次風(fēng)險(xiǎn)。
Finally, there is the smoke exhaust fire damper (marked as PFHF in the national standard), which serves as the "ultimate defense line" of the smoke exhaust system. The smoke exhaust fire damper of Chuanxiao is mainly installed near the smoke exhaust system, smoke exhaust fan, and smoke prevention partition, with dual functions of smoke exhaust and fire prevention. The core operating temperature is 280 ℃, which is the critical value for the flue gas to reach a dangerous temperature. When the flue gas temperature in the pipeline rises to 280 ℃, the valve automatically closes to prevent the high-temperature flue gas from spreading to other areas. More importantly, the Chuanxiao smoke exhaust fire damper installed near the smoke exhaust fan has a interlock shutdown function. After the valve is closed, it can automatically trigger the fan to stop running, avoiding damage caused by the fan inhaling high-temperature smoke and reducing the risk of secondary fire.
值得注意的是，消防閥的選型與安裝，不僅要分清三類(lèi)閥門(mén)的差異，更要選擇合規(guī)優(yōu)質(zhì)的產(chǎn)品。據(jù)行業(yè)調(diào)研，市面上40%的廉價(jià)消防閥存在動(dòng)作溫度偏差、密封性能不達(dá)標(biāo)等問(wèn)題，而川消消防閥均通過(guò)ISO9001質(zhì)量管理體系認(rèn)證，動(dòng)作溫度偏差控制在±3℃以?xún)?nèi)，密封性能符合國(guó)標(biāo)要求，同時(shí)川消提供專(zhuān)業(yè)的選型指導(dǎo)與安裝調(diào)試服務(wù)，避免因選型、安裝不當(dāng)留下消防隱患。
It is worth noting that the selection and installation of fire valves should not only distinguish the differences between the three types of valves, but also choose compliant and high-quality products. According to industry research, 40% of cheap fire valves on the market have problems such as operating temperature deviation and inadequate sealing performance. However, Chuanxiao fire valves have passed ISO9001 quality management system certification, with operating temperature deviation controlled within ± 3 ℃ and sealing performance meeting national standards. Chuanxiao also provides professional selection guidance and installation and commissioning services to avoid fire hazards caused by improper selection and installation.
川消提醒，建筑消防系統(tǒng)中，三類(lèi)消防閥各司其職、不可替代：防火閥阻斷初期煙氣，排煙閥排出火災(zāi)煙氣，排煙防火閥守住排煙系統(tǒng)最后防線。無(wú)論是工程施工選型，還是后期運(yùn)維檢查，準(zhǔn)確區(qū)分三類(lèi)閥門(mén)，選擇像川消這樣合規(guī)可靠的產(chǎn)品，才能確保火災(zāi)發(fā)生時(shí)各系統(tǒng)正常運(yùn)轉(zhuǎn)。據(jù)統(tǒng)計(jì)，選用川消消防閥的建筑，消防隱患整改率降低68%，火災(zāi)時(shí)煙氣控制達(dá)標(biāo)率提升75%。
Chuanxiao reminds that in the building fire protection system, the three types of fire valves play their respective roles and cannot be replaced: fire dampers block initial smoke, smoke exhaust valves discharge fire smoke, and smoke exhaust fire dampers guard the last line of defense of the smoke exhaust system. Whether it is engineering construction selection or later operation and maintenance inspection, accurately distinguishing the three types of valves and selecting compliant and reliable products like Chuanxiao can ensure the normal operation of various systems in the event of a fire. According to statistics, buildings equipped with Chuanxiao fire valves have a 68% reduction in the rectification rate of fire hazards and a 75% increase in the compliance rate of smoke control during fires.
綜上，消防閥的正確區(qū)分與選型，是建筑消防安全的基礎(chǔ)，容不得半點(diǎn)馬虎。川消憑借60余年的技術(shù)沉淀與品質(zhì)堅(jiān)守，不僅為市場(chǎng)提供優(yōu)質(zhì)的消防閥門(mén)產(chǎn)品，更致力于普及消防知識(shí)，幫從業(yè)者避開(kāi)選型誤區(qū)。牢記三類(lèi)消防閥的動(dòng)作溫度、安裝位置與核心功能，選擇合規(guī)可靠的品牌與產(chǎn)品，才能筑牢建筑消防安全防線，從源頭規(guī)避火災(zāi)隱患，守護(hù)人員與財(cái)產(chǎn)安全。
In summary, the correct differentiation and selection of fire valves are the foundation of building fire safety and cannot tolerate any carelessness. With over 60 years of technological accumulation and quality assurance, Chuanxiao not only provides high-quality fire valve products to the market, but also strives to popularize fire knowledge and help practitioners avoid selection errors. Keeping in mind the operating temperature, installation location, and core functions of the three types of fire valves, choosing compliant and reliable brands and products is necessary to build a strong defense line for building fire safety, avoid fire hazards from the source, and safeguard personnel and property safety.
