Selection of Chuanxiao nozzle
1、對(duì)于噴頭的噴孔易被外部異物堵塞的場(chǎng)所，應(yīng)選用具有相應(yīng)防護(hù)措施且不影響細(xì)水霧噴放效果的噴頭，如粉塵場(chǎng)所應(yīng)選用帶防塵罩（端蓋）的噴頭，但在噴霧時(shí)不應(yīng)阻擋水霧和對(duì)人員造成的傷害；
1. For places where the nozzle hole is easy to be blocked by external foreign matters, the nozzle with corresponding protective measures that will not affect the spray effect of water mist shall be selected. For dust places, the nozzle with dust cover (end cover) shall be selected, but the water mist and personal injury shall not be blocked during spray;
2、對(duì)于電子數(shù)據(jù)處理機(jī)房、通信機(jī)房的地板夾層，宜選擇適用于低矮空間的噴頭；
2. For the floor mezzanine of electronic data processing room and communication room, the nozzle suitable for low space should be selected;
3、對(duì)于閉式系統(tǒng)，應(yīng)選擇響應(yīng)時(shí)間指數(shù)不大于50(m·s）0.5的噴頭，其公稱動(dòng)作溫度宜高于環(huán)境溫度高溫度30℃，且同一防護(hù)區(qū)內(nèi)應(yīng)采用相同熱敏性能的噴頭；
3. For the closed system, the nozzle with response time index no more than 50 (m · s) 0.5 shall be selected, its nominal operating temperature should be 30 ℃ higher than the ambient temperature, and the nozzle with the same thermal sensitivity should be used in the same protection zone;
4、對(duì)于腐蝕性環(huán)境，應(yīng)選用采用防腐材料或具有防腐鍍層的噴頭；
4. For corrosive environment, the nozzle with anti-corrosion materials or anti-corrosion coating shall be selected;
5、對(duì)于電氣火災(zāi)危險(xiǎn)場(chǎng)所的細(xì)水霧滅火系統(tǒng)，不宜選用撞擊霧化型細(xì)水霧噴頭。
5. For the water mist fire extinguishing system in the electrical fire hazard area, the impact atomization water mist nozzle should not be selected.
川消噴頭的布置要求
Layout requirements of Chuanxiao sprinkler
閉式系統(tǒng)的噴頭布置應(yīng)能保證細(xì)水霧噴放均勻并完全覆蓋保護(hù)區(qū)域；噴頭與墻壁的距離不應(yīng)大于噴頭大布置間距的1/2；噴頭與其他遮擋物的距離應(yīng)保證遮擋物不影響噴頭正常噴放細(xì)水霧，當(dāng)無法避免時(shí)，應(yīng)采取補(bǔ)償措施；噴頭的感溫組件與頂棚或梁底的距離不宜小于75mm，且不宜大于150mm。當(dāng)場(chǎng)所內(nèi)設(shè)置吊頂時(shí)，噴頭可貼鄰吊頂布置。
The sprinkler arrangement of the closed system shall ensure that the fine water mist is sprayed evenly and completely covers the protection area; The distance between the nozzle and the wall shall not be greater than 1/2 of the large spacing of the nozzle; The distance between the nozzle and other obstructions shall ensure that the obstructions do not affect the normal spray of fine water mist by the nozzle. When it is unavoidable, compensation measures shall be taken; The distance between the temperature sensing component of the nozzle and the ceiling or beam bottom should not be less than 75mm, and should not be more than 150mm. When the ceiling is set in the site, the sprinkler can be arranged close to the ceiling.
開式系統(tǒng)的噴頭布置與閉式系統(tǒng)的噴頭布置要求相同，但對(duì)于電纜隧道或夾層，噴頭宜布置在電纜隧道或夾層的上部，并應(yīng)能使細(xì)水霧完全覆蓋整個(gè)電纜或電纜橋架。
The sprinkler arrangement of the open system is the same as that of the closed system, but for the cable tunnel or interlayer, the sprinkler should be arranged at the upper part of the cable tunnel or interlayer, and should be able to completely cover the entire cable or cable bridge with fine water mist.
噴頭布置應(yīng)能保證細(xì)水霧完全包容或覆蓋保護(hù)對(duì)象或部位，噴頭與保護(hù)對(duì)象的距離不宜小于0.5m。用于保護(hù)室內(nèi)油浸變壓器時(shí)，變壓器高度超過4m的，噴頭宜分層布置；冷卻器距變壓器本體超過0.7m的，應(yīng)在其間隙內(nèi)增設(shè)噴頭；噴頭不宜直接對(duì)準(zhǔn)高壓進(jìn)線套管；變壓器下方設(shè)置集油坑的，噴頭布置應(yīng)能使細(xì)水霧完全覆蓋集油坑。
The nozzle arrangement shall ensure that the water mist completely covers or covers the protected object or part, and the distance between the nozzle and the protected object shall not be less than 0.5m. When it is used to protect indoor oil-immersed transformer, if the transformer height exceeds 4m, the nozzle should be arranged in layers; If the distance between the cooler and the transformer body is more than 0.7m, the nozzle shall be added in its gap; The nozzle should not be directly aligned with the high-voltage incoming bushing; If an oil sump is set under the transformer, the nozzle arrangement shall be able to completely cover the oil sump with fine water mist.
系統(tǒng)應(yīng)按噴頭的型號(hào)、規(guī)格儲(chǔ)存?zhèn)溆脟婎^，其數(shù)量不應(yīng)小于相同型號(hào)、規(guī)格噴頭實(shí)際設(shè)計(jì)使用總數(shù)的1%，且分別不小于5只。更多相關(guān)內(nèi)容就來我們網(wǎng)站
