進口燃氣電磁閥
進口燃氣電磁閥產品概述
美國WORK是新型的燃氣管道工程的安全配套裝置,主要應用如下:與可燃氣體泄漏監(jiān)測儀器相連接。當儀器檢測到可燃氣體泄漏時,自動快速關閉主供氣體閥門,切斷燃氣的供給,及時制止惡性事故的發(fā)生。
主要技術參數
詳細技術參數:http:///cn/products/712.htm
產品規(guī)格:DN15~DN500
閥體材質:鑄鋼,不銹鋼等
適用介質:煤氣、天然氣、液化氣、沼氣、甲烷、瓦斯等氣體或燃油等
溫度范圍:-40~+150℃
介質粘度:小于50C St(大于時需定制)
防護性能:防水、防爆(Exd IICT5)、防腐
接線方式:接線座式;引線式;插頭式
控制方式:常開、常閉
電源電壓:DC12~127V; AC36~380V
連接方式:內螺紋、法蘭、外螺紋
泄 漏 量:零
工作原理
A:當安全閥需要打開時,旋下防護罩(如防護罩中間有螺紋孔型,將他旋在聯動桿上當手柄使用),用力拉手柄,閥打開。
B:當安全閥需要關閉時,線圈通電不超過30秒鐘,閥1秒內迅速關閉。
特殊功能:
信號反饋:當閥打開時,信號公共線和開信號線接通;當閥關閉時,信號公共線和關信號線接通。
手動功能:安全閥需要關閉時,旋下手動防護罩,用力按手動柄,電磁閥關閉。
