德國洛克進口油用截止閥的工作原理與使用方法 

一、進口油用截止閥描述：

德國《LOCKE》洛克進口油用截止閥（Globe valve for oil）其關鍵部件金屬波紋管，下端與閥桿組件采用自動滾焊焊接，上端與連接板自動滾焊焊接，在流體介質和大氣之間形成一個金屬屏障，確保閥桿零泄漏。

The key part of globe valve for oil imported from Locke, Germany, is metal bellows. The lower end is welded with the stem assembly by automatic roll welding, and the upper end is welded with the connecting plate by automatic roll welding. A metal barrier is formed between the fluid medium and the atmosphere to ensure zero leakage of the valve stem.

二、進口油用截止閥結構優(yōu)點：

密封可靠、性能優(yōu)良；

密封面、耐磨、耐腐

抗磨擦性能好、長壽命長；

閥桿氮化處理，抗腐和抗磨擦性能強；
