美標鍛鋼球閥產品說明：
Q47F-150LB/300LB/600LB美標鍛鋼球閥結構簡單，密封性能好，用于截斷或接通管路中的介質，選用不同的材質，可分別適用于水、蒸汽、用品、液化氣、天然氣、煤氣、硝酸、醋酸、氧化性等介質。浮動式球閥主要包括：一片式、兩片式、鍛鋼分體式設計。采用閥桿防吹出設計、防靜電結構的設計、低泄漏結構的設計、防止閥桿的磨損和誤操作的設計、防火結構的設計等。所有的浮動球閥均按照GB/T 12237設計，并且防火試驗滿足API 607的要求。閥桿采用防吹出結構設計的整體T形結構，即使在閥腔異常升壓以及填料壓板失效等極端情況下，也能保證閥桿不會被介質吹出。美標球閥的閥桿嵌入閥體內部，具有倒密封的功能，倒密封的密封力隨著介質壓力的增高而增大，故能在各種壓力下均能確保閥桿的可靠密封。
美標鍛鋼球閥防靜電結構的設計：
美標球閥防靜電結構采用彈簧-鋼球式靜電引出裝置，使球體與閥體之間直接形成靜電通道的球閥或通過閥桿使球體之間形成靜電通道的球閥從而可將球體與閥座開關過程中摩擦產生的靜電通過閥體引到地，避免靜電火花可能引起的火災或爆炸等危險。
