眾海消防推薦：鑄鋼閘閥有一個(gè)零配件叫閥桿，這個(gè)閥桿應(yīng)該怎么樣選擇呢？又哪些注意事項(xiàng)呢？常見的閘閥閥桿且易堆積焊渣、石塊、泥沙等雜物,不利于密封和流面，而且部分廠家的彈性座封閘閥采用平底式全流域直通式設(shè)計(jì),不易堆積雜物,確保密封可靠,可以使流體暢通無(wú)阻。其實(shí)就是我們經(jīng)常去閥門配件的市場(chǎng)上面買的閥桿，標(biāo)準(zhǔn)的好一些，可以批量生產(chǎn)，基本數(shù)據(jù)和尺寸都有個(gè)參考的標(biāo)準(zhǔn)，如果是非標(biāo)的話就要另外定制了，還有個(gè)重要的事情就是：鑄鋼閘閥的閥桿也有材質(zhì)的區(qū)別的，這個(gè)小小的配件現(xiàn)在已經(jīng)被很多廠家作為“動(dòng)手腳”地方，為了讓自己的利益比較大化，或者是為了爭(zhēng)取一個(gè)客戶，讓自己降價(jià)，通常的做法就是，閥門有304的做，但是閥桿卻是321或者其他更差的，買家也很少去在意這個(gè)小配件，這也導(dǎo)致很多老實(shí)巴交的老板，怎么也想不通，為什么自己一個(gè)閥門304的做起來(lái)的都要28塊，可有的廠家賣出去才26元。如果沒(méi)有太大的影響還好，這一些也是一種小小的銷售技巧，不過(guò)還是希望不要擾亂整個(gè)閥門的銷售市場(chǎng)。 </p><p> 不銹鋼截止閥的工作過(guò)程作者：巨業(yè)閥門來(lái)源：永嘉縣巨業(yè)閥門制造有限公司發(fā)布于：2018-1-1513:41:14不銹鋼截止閥是采用不銹鋼為材質(zhì)的截止閥，其啟閉件是塞形的閥瓣，密封面呈平面或錐面，閥瓣沿流體的中心線作直線運(yùn)動(dòng)。閥桿的運(yùn)動(dòng)形式，也有升降旋轉(zhuǎn)桿式，不銹鋼截止閥只適用于全開和全關(guān)，不允許作調(diào)節(jié)和節(jié)流。不銹鋼截止閥的工作過(guò)程：不銹鋼截止閥屬于強(qiáng)制密封式閥門，所以在閥門關(guān)閉時(shí)，必須向閥瓣施加壓力，以強(qiáng)制密封面不泄漏。當(dāng)介質(zhì)由不銹鋼截止閥閥瓣下方進(jìn)入閥門時(shí)，操作力所需要克服的阻力，是閥桿和填料的摩擦力與由介質(zhì)的壓力所產(chǎn)生的推力，關(guān)閥門的力比開閥門的力大，所以閥桿的直徑要大，否則會(huì)發(fā)生閥桿頂彎的故障。介質(zhì)流向就改由閥瓣上方進(jìn)入閥腔，這時(shí)在介質(zhì)壓力作用下，關(guān)閥門的力小，而開閥門的力大，閥桿的直徑可以相應(yīng)地減少，同時(shí)，在介質(zhì)作用下，這種形式的閥門也較嚴(yán)密。不銹鋼截止閥要水平安裝，截止閥開啟時(shí)，閥瓣的開啟高度，為公稱直徑的25%～30%時(shí)，流量已達(dá)到比較大，表示閥門已達(dá)全開位置，所以截止閥的全開位置，應(yīng)由閥瓣的行程來(lái)決定。減壓閥,不一樣的閥門,限時(shí)福利!</p><div
