高壓細(xì)水霧噴頭根據(jù)不同的應(yīng)用場(chǎng)所，可分為開(kāi)式噴頭、閉式噴頭、高大空間專用噴頭、超細(xì)水霧噴頭等100多種不同應(yīng)用的高壓細(xì)水霧噴頭。那么為什么閉式的細(xì)水霧噴頭應(yīng)用較少？下面
川消小編為您解答吧。
High pressure water mist sprayers can be divided into more than 100 types of high pressure water mist sprayers with different applications, such as open type sprayers, closed type sprayers, special sprayers for large and large spaces, ultra-fine water mist sprayers, etc. So why are closed water mist nozzles seldom used? Now let's answer it for you.
其中應(yīng)用較多的應(yīng)該是開(kāi)式噴頭，因?yàn)殚_(kāi)式噴頭不帶感溫、閉鎖裝置，處于常開(kāi)狀態(tài)?；馂?zāi)發(fā)生時(shí)，區(qū)域內(nèi)的所有開(kāi)式噴頭開(kāi)始出水滅火。而閉式噴頭之所以應(yīng)用較少，原因是它是一種常閉噴頭，噴頭的感溫、閉鎖裝置只有在預(yù)定的溫度環(huán)境下，才會(huì)爆破，開(kāi)啟噴頭。所以火災(zāi)發(fā)生時(shí)，閉式噴頭只有身處于火焰之中，或臨近火源時(shí)，才會(huì)開(kāi)啟出水滅火。
Among them, open type nozzles are widely used because they are normally open without temperature sensing and locking devices. When a fire occurs, all open sprinklers in the area begin to extinguish the fire. The reason why the closed sprinkler is seldom used is that it is a normally closed sprinkler. The temperature sensing and locking devices of the sprinkler will burst and open the sprinkler only under the predetermined temperature environment. Therefore, when a fire occurs, the closed sprinkler willonly open the water to extinguish the fire when it is in the flame or near the fire source.
另外，閉式噴頭的可靠性不高，受到外力可能會(huì)破碎，造成誤噴射，所以只能設(shè)置在一些對(duì)水不敏感的部位；還有閉式噴頭只要一爆破，用過(guò)一次后就不能再重復(fù)使用，因此費(fèi)用方面也要考慮進(jìn)去。所以，閉式噴頭只適用于閉式系統(tǒng)。
In addition, the reliability of the closed sprinkler is not high, which may be broken by external forces, resulting in spurting by mistake, so it can only be set in some parts that are not sensitive to water; Also, once the closed sprinkler is blasted, it cannot be reused after being used once, so the cost should also be taken into account. Therefore, the closed sprinkler is only applicable to the closed system.
此外閉式系統(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(wú)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。
In addition, the sprinkler arrangement of the closed system shall ensure that the water mist can be sprayed evenly and completely cover the protected area; The distance between the sprinkler and the wall shall not be greater than 1/2 of the large spacing of the sprinkler; The distance between the nozzle and other obstructions shall ensure that the obstructions will not affect the normal spraying of fine water mist by the nozzle. If it is unavoidable, compensation measures shall be taken; The distance between the temperature sensing component of the sprinkler 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 station, the sprinkler can be arranged next to the ceiling.
閉式噴頭密封性能試驗(yàn)，隨機(jī)從每批到場(chǎng)噴頭中抽取1%，且不少于5只作為試驗(yàn)噴頭。當(dāng)1只噴頭試驗(yàn)不合格時(shí)，再抽取2%，且不少于10只的到場(chǎng)噴頭進(jìn)行重復(fù)試驗(yàn)。更多相關(guān)內(nèi)容就來(lái)我們網(wǎng)站

For the sealing performance test of closed sprinklers, 1% of the sprinklers in each batch shall be selected randomly, and no less than 5 sprinklers shall be used as test sprinklers. When one nozzle fails to pass the test, another 2% and no less than 10 nozzles shall be sampled to repeat the test. More relevant content will come to our website http://www.xintli.net Consult!
