style="font-size:16px;">球閥的種類，你了解多少？球閥分類方式很多，以下主要介紹四種分類方式。球閥一般是即開即關(guān)使用，密封性也沒有針閥，膜片閥好！如果用在高壓易燃易爆氣體上，氣體流速太快，有一定的風(fēng)險(xiǎn)系數(shù)，球閥通徑比較大，一般和口徑相同，所以截流比較小，通過性比較好！球閥按照操作原理一般分為手動，氣動，電動！(1).按球體結(jié)構(gòu)型式分類：浮動球式、固定球式。主要產(chǎn)品例如：法蘭浮動球閥、固定球兩片式球閥、固定球軟密封球閥、襯氟球閥、固定球不銹鋼高溫球閥等。(2).按球閥流通型式分類：直通式、三通式、四通式、五通式。主要產(chǎn)品例如：直通一片式球閥、三通法蘭球閥等。(3).按閥體裝配形式分類：一體式、二體式、三體式、上裝式。主要產(chǎn)品例如：兩體襯氟球閥、三體不銹鋼球閥、上裝式球閥等。(4).按閥體</span><span style="font-size:16px;">流道直徑分類：全通徑式、縮徑式。主要產(chǎn)品例如：全通徑法蘭球閥、縮徑式球閥等。</span> </p><p> <span style="font-size:16px;">球閥是由閥體和閥座構(gòu)成，雙倍運(yùn)動閥座是當(dāng)中腔壓力大于出口壓力時(shí)，使閥座壓緊球體，密封圈產(chǎn)生彈塑性變形實(shí)現(xiàn)密封。該閥使用時(shí)，一旦上游密封意外失效產(chǎn)生泄漏，下游閥座實(shí)現(xiàn)密封。雙級密封式閥座對于承受較大密封力的采用橡膠和塑料組合密封結(jié)構(gòu)，橡膠主要起密封作用，塑料起支承和輔助密封雙重作用。內(nèi)調(diào)節(jié)式閥座是閥座與球體之間的密封比壓靠內(nèi)調(diào)整螺母調(diào)節(jié)，其優(yōu)點(diǎn)是沒有向外的泄漏點(diǎn)。外調(diào)節(jié)式閥座是閥座與球體之間的密封比壓靠外部調(diào)節(jié)螺塞壓緊楔塊使伸縮套產(chǎn)生位移進(jìn)行調(diào)整。波紋管式閥座一般采用電子束焊或氬弧焊與閥座和導(dǎo)向套相連。設(shè)計(jì)時(shí)，應(yīng)保證閥座密封中心小于波紋管中徑，此結(jié)構(gòu)具有密封性可靠，彈性補(bǔ)償范圍大，三維空間靈活的特點(diǎn)。</span>

style="font-size:16px;">氣動球閥的強(qiáng)度試驗(yàn)應(yīng)在球體半開狀態(tài)下進(jìn)行。①浮動式球閥密封性試驗(yàn)：將閥處于半開狀態(tài)，一端引入試驗(yàn)介質(zhì)，另一端封閉；將球體轉(zhuǎn)動幾次，閥門處于關(guān)閉狀態(tài)時(shí)打開封閉端檢查，同時(shí)檢查填料和墊片處密封性能，不得有滲漏現(xiàn)象。然后從另一端引入試驗(yàn)介質(zhì)，重復(fù)上述試驗(yàn)。②固定式球閥密封性試驗(yàn)：在試驗(yàn)前將球體空載轉(zhuǎn)動幾次，固定式球閥處于關(guān)閉狀態(tài)，從一端引人試驗(yàn)介質(zhì)至規(guī)定值；用壓力表檢查引入端密封性能，使用壓力表精度0．5～1級，量程為試驗(yàn)壓力的1．6倍。在規(guī)定時(shí)問內(nèi)，沒有降壓現(xiàn)象為合格；再從另一端引入試驗(yàn)介質(zhì)，重復(fù)上述試驗(yàn)。然后，將閥門處于半開狀態(tài)，兩端封閉，內(nèi)腔充滿介質(zhì)，在試驗(yàn)壓力下檢查填料和墊片處，不得有滲漏。③三通球閥應(yīng)在各個(gè)位置上進(jìn)行密封性試驗(yàn)。</span>
