美標(biāo)鍛鋼球閥產(chǎn)品說明：
Q47F-150LB/300LB/600LB美標(biāo)鍛鋼球閥結(jié)構(gòu)簡單，密封性能好，用于截斷或接通管路中的介質(zhì)，選用不同的材質(zhì)，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(zhì)。浮動式球閥主要包括：一片式、兩片式、鍛鋼分體式設(shè)計(jì)。采用閥桿防吹出設(shè)計(jì)、防靜電結(jié)構(gòu)的設(shè)計(jì)、低泄漏結(jié)構(gòu)的設(shè)計(jì)、防止閥桿的磨損和誤操作的設(shè)計(jì)、防火結(jié)構(gòu)的設(shè)計(jì)等。所有的浮動球閥均按照GB/T 12237設(shè)計(jì)，并且防火試驗(yàn)滿足API 607的要求。閥桿采用防吹出結(jié)構(gòu)設(shè)計(jì)的整體T形結(jié)構(gòu)，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(zhì)吹出。美標(biāo)球閥的閥桿嵌入閥體內(nèi)部，具有倒密封的功能，倒密封的密封力隨著介質(zhì)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(biāo)鍛鋼球閥防靜電結(jié)構(gòu)的設(shè)計(jì)：
美標(biāo)球閥防靜電結(jié)構(gòu)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(guān)過程中摩擦產(chǎn)生的靜電通過閥體引到地，避免靜電火花可能引起的火災(zāi)或爆炸等危險。
