美國泰樂TYLER進口天然氣截止閥
產(chǎn)品描述-
美國泰樂TYLER進口天然氣截止閥采用成形聚四氟乙烯作為密封填料，由填料壓蓋提供初始密封，當發(fā)生磨損引起的動密封泄漏時，可用填料壓蓋螺母進行調(diào)整，燃氣截止閥在閥瓣的金屬密封面上設置一溝槽，鑲裝一軟密封環(huán)與閥座金屬密封面形成軟硬雙重密封結構，提高了密封性能，避免了金屬密封旋轉摩擦產(chǎn)生靜電，引起的火花。
應用范圍-
天然氣截止閥適用于城市液化氣石油氣貯備站,也使用于煉油廠,石油化工廠,石油化工廠的液化氣系統(tǒng),產(chǎn)品涉及到非腐蝕性流體輸送場合和液化氣站、氣體、燃氣管道上作輸送或切斷介質的作用。
結構特點-
密封面間磨擦力小;
防火防靜電結構;
耐磨損,耐腐蝕,壽命長;
尼龍閥瓣,有彈性密封更可靠;
工作行程小，啟閉時間短;
填料壓蓋螺母進行調(diào)整,提高了密封性能;
