杜瓦瓶在使用中須遵循的規則

時間:2017-12-07 09:15來源: 作者:班德液氮罐 點擊:

  隨著特殊氣體行業的不斷發展,對杜瓦瓶這樣的用來裝運特殊氣體的儲罐,在行業中的需求越來越大,其作用也是日益突出,盡管杜瓦瓶等多種儲罐產品在行業內都獲得了較好的發展,但是對于杜瓦瓶的一些相關知識,估計很少有人了解,雖然其應用廣泛但是在我們日常生活中并不常見,對此我們需要對其操作規程具有一定的了解:

  1、確保作業場合具有優秀的透風條件、空氣中的氧氣含量應高于18%(體積濃度)。

  2、杜瓦瓶儲罐上的一切設備 (包括連接件、管道以及各閥門)不得沾有油類、潤滑脂等可燃性物資。

  3、閥門應遲緩用手翻開。如閥門破壞了或許沒法用手翻開,不得用扳手等東西強迫翻開,應當即與林德氣體公司聯絡。

  4、如閥門等設備凍結了,應運用熱水等合適法子進行凍結。不得運用明火來凍結,也不得運用錘子等東西關于它們進行敲擊。制止帶壓修理或許緊固儲罐/杜瓦罐上的任何部位。

  5、不得在地下室、半地下室或許低凹處等透風條件差的場所運用液氮。
