進口波紋管閘閥德國洛克品牌產品列表

進口波紋管閘閥結構特點：

①波紋管密封閘閥，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；

②雙重的密封設計（波紋管+填料）若波紋管失效，閥桿填料也會避免泄漏，并符合國際密封標準；

③閥蓋上自帶有加脂接頭，可直接對閥桿、螺母和軸套進行潤滑，不像傳統的只對螺紋加潤滑油；

④人體工程學設計手輪，使用壽命更長，操作輕松便捷，更安全可靠。

進口波紋管閘閥產品簡介：

德國洛克《DE LOCKE》進口波紋管閘閥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；雙重的密封設計(波紋管+填料)若波紋管失效，閥桿填料也會避免泄漏。

Introduction of imported bellows gate valve products:
The metal bellows, the key component of German Rockwell "de Locke" imported bellows gate valve, adopts automatic roll welding at the lower end and the valve stem assembly, and automatic roll welding at the upper end and the connecting plate, forming a metal barrier between the fluid medium and the atmosphere to ensure zero leakage of the valve stem; the double sealing design (bellows + packing) can avoid leakage of the valve stem packing if the bellows fails.
