高壓細水霧噴頭根據不同的應用場所，可分為開式噴頭、閉式噴頭、高大空間專用噴頭、超細水霧噴頭等100多種不同應用的高壓細水霧噴頭。那么你知道為什么閉式的細水霧噴頭應用較少嗎？下面

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. Do you know why closed water mist nozzles are less used? Now, let's answer for you.
閉式噴頭之所以應用較少，原因是它是一種常閉噴頭，噴頭的感溫、閉鎖裝置只有在預定的溫度環境下，才會爆破，開啟噴頭。所以火災發生時，閉式噴頭只有身處于火焰之中，或臨近火源時，才會開啟出水滅火。
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 will only 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，受到外力可能會破碎，造成誤噴射，所以只能設置在一些對水不敏感的部位；還有閉式噴頭只要一爆破，用過一次后就不能再重復使用，因此費用方面也要考慮進去。所以，閉式噴頭只適用于閉式系統。
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.
此外使用之前要了解該產品的注意事項，如：
In addition, you should know the precautions of the product before use, such as:
應嚴格按照環境高溫度來選定噴頭溫級。在不同的環境溫度場所設置噴頭時，噴頭的公稱動作溫度宜比環境高溫度高30℃。
The nozzle temperature level shall be selected in strict accordance with the high ambient temperature. The nominal operating temperature of the nozzle should be 30 ℃ higher than the high ambient temperature when the nozzle is set at different ambient temperature locations.
在有腐蝕性介質存在的場所，應選用經防腐處理的噴頭，或選用耐腐蝕的玻璃球灑水噴頭。
In places with corrosive media, the nozzle with anti-corrosion treatment or the anti-corrosion glass ball sprinkler shall be selected.
建筑物、構筑物設有自動噴水滅火系統時，應有庫存備用噴頭，其數量不應少于總安裝個數的1%，且每種類型和不同溫標的備用噴頭數均不應少于10個。等等。
When buildings and structures are equipped with automatic sprinkler systems, they shall have spare sprinklers in stock, which shall not be less than 1% of the total number of sprinklers installed, and the number of spare sprinklers of each type and different temperature scales shall not be less than 10. wait.
The closed water curtain sprinkler starts to prevent the spread of fire, and the fire resistance performance of doors and windows, door panels, fire rolling shutters, etc. plays a blocking role. Come here if you need https://www.hcseaworld.com Get in touch!
