一、產品特點:
1.襯氟球閥是采用FEP襯里層的球閥,具有極高的化學穩定性,可以適用除“熔融堿金屬和元素氟”,以外其它任何強腐蝕性質;
2.襯氟球閥采用全通徑、浮動球結構,閥門可在整個壓力范圍內進行無泄漏關閉,更便于管路系統的通球掃線和管路維護;
3.襯氟球閥啟閉件球件與閥桿鑄(鍛)為一體,杜絕了由于壓力變化引起閥桿沖出承壓件內的可能性,從根本上保證了工程中的使用**性;
4.襯氟球閥結構緊湊合理,閥體內腔空間*小,減小了介質滯留,另外,特殊的模壓工藝,使密封面致密度良好,加之人字環形PTFE填料組合,使閥門達到零泄漏;
5.兩片式、三片式結構可適應各種不同要求的管路系統和工況條件,其中三片球閥允許主閥體與兩側閥體分離,可實現在線快速更換、維修。
二 、設計規范
遵循GB 12237/API 608 /API 6D 標準。
