美標(biāo)球閥產(chǎn)品說(shuō)明:
AQ341F-150LB/300LB/600LB美標(biāo)球閥結(jié)構(gòu)簡(jiǎn)單,密封性能好,用于截?cái)嗷蚪油ü苈分械慕橘|(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(dòng)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(dòng)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情況下,也能保證閥桿不會(huì)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)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(guò)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(kāi)關(guān)過(guò)程中摩擦產(chǎn)生的靜電通過(guò)閥體引到大地,避免靜電火花可能引起的火災(zāi)或爆炸等危險(xiǎn)。
