金屬硬密封球閥

硬質表面

HVOF & 其他處理

金屬硬密封球閥的設計主要用於嚴峻的工作環境,例如高溫或流體中含有堅硬的顆粒或纖維。 HVOF (High Velocity Oxy-Fuel =高速火焰熔射) 可以提供各種硬質表面材料,例如碳化鎢,鈷,鉻碳化物,以適應各種不同工況。 除HVOF之外,我們還可以提供鍍鉻處理或表面噴焊。

金屬球墊球閥更多是使用於蒸汽環境,配合良好的加工設計與研磨技術, 陸功 Zipson 的硬密封球閥在市場上受到客戶的喜愛。

金屬球墊扭力

單向或雙向止漏?

對於浮動球設計的金屬硬密封球閥,其優勢是透過流體的壓力,能提供較好的密封能力。 但反面來說, 在壓力下因球與硬質球墊磨擦反而會產生較高的操作扭力。

為避免操作扭力過大問題,客戶需要遵循陸功的金屬球墊球閥選型指南文件,以確保球閥在建議的壓差內操作。 如果壓差超過建議的壓力,則操作扭力可能會過高,然後損壞中軸或球塞溝槽。
