style="text-indent:25px">氣動球閥是一種常用的控制元件，是由旋塞閥演變而來具有相同的旋轉(zhuǎn)90度動作，不同的是旋塞體是球體，有圓形通孔或通道通過其軸線。本文主要介紹氣動球閥的用途及優(yōu)點(diǎn)，希望可以幫助大家更好的應(yīng)用產(chǎn)品。氣動球閥的工作原理是靠旋轉(zhuǎn)閥芯來使閥門暢通或閉塞。氣動球閥開關(guān)輕便，體積小，可以做成很大口徑，密封可靠，結(jié)構(gòu)簡單，維修方便，密封面與球面常在閉合狀態(tài)，不易被介質(zhì)沖蝕，在各行業(yè)得到普遍的應(yīng)用。氣動球閥和旋塞閥是同屬一個(gè)類型的閥門，只有它的關(guān)閉件是個(gè)球體，球體繞閥體中心線作旋轉(zhuǎn)來達(dá)到開啟、關(guān)閉的一種閥門。氣動球閥在管路中主要用來做切斷速度快、分配和改變介質(zhì)的流動方向。</p><p style="text-indent:25px">當(dāng)工作溫度升高時(shí)，氣動閥門閥體的耐壓會降低。例如，公稱壓力為6.4MPa(PN64)的碳鋼控制閥，用于300℃時(shí)的耐壓為5.2MPa，用400℃時(shí)的耐壓為4.1MPa，用于450℃時(shí)的耐壓為2.9MPa。因此，控制閥公稱壓力的確定不*要根據(jù)較高工作壓力，還需根據(jù)較高工作溫度和材質(zhì)特性，而不**只需滿足公稱壓力大于工作壓力。主要種類：氣動V型調(diào)節(jié)球閥、氣動O型切斷球閥、扭距式汽缸球閥、電磁隔膜閥、氣動直行程式隔膜閥、電動閥。氣動V型球閥用途與特點(diǎn)：用途是一種直角回轉(zhuǎn)結(jié)構(gòu)，它與閥門定位器配套使用，可實(shí)現(xiàn)比例調(diào)節(jié)；。氣動閥門限位開關(guān)是什么？</p><div

style="text-indent:25px">氣動蝶閥用于固體物料的控制，往往是在罐底做為放料閥來用的，如水泥罐、石粉罐等的罐底，用來放料與快速切斷。因?yàn)榉蹓m物料大多含有或大或小的顆粒，對閥門密封面的磨損是毋庸置疑的，選型不當(dāng)，會極大降低閥門的使用壽命，或很快造成閥門內(nèi)漏，影響繼續(xù)使用。安裝環(huán)境：本產(chǎn)品不論室內(nèi)、露天均能使用，但在有腐蝕性的介質(zhì)和易生銹的場合，要使用相應(yīng)的材料組合。特殊工況使用可咨詢我司。裝置場所：必須安裝在能夠安全操作，且容易保養(yǎng),檢查及維修之場所。周圍環(huán)境：溫度-20℃~+70℃,濕度90%RH以下。安裝前應(yīng)首先根據(jù)閥門上的銘牌標(biāo)志，檢查閥門是否符合工況使用要求。氣動閥門關(guān)閉狀況下，兩側(cè)分別承受1.1倍閥門工壓值，無滲漏。氣動閥的閥門供應(yīng)商</p><p
