style="text-indent:25px">管道閥門(mén)的精髓：一.截止和開(kāi)放介質(zhì)流道為直通式的閥門(mén)，其流阻較小，通常選擇作為截止和開(kāi)放介質(zhì)用的閥門(mén)。向下閉合式閥門(mén)(截止閥、柱塞閥)由于其流道曲折，流阻比其他閥門(mén)高，故較少選用。在允許有較高流阻的場(chǎng)合，可選用閉合式閥門(mén)。二.控制流量通常選擇易于調(diào)節(jié)流量的閥門(mén)作為控制流量用。向下閉合式閥門(mén)(如截止閥)適于這一用途，因?yàn)樗拈y座尺寸與關(guān)閉件的行程之間成正比關(guān)系。旋轉(zhuǎn)式閥門(mén)(旋塞閥、蝶閥、球閥)和撓曲閥體式閥門(mén)(夾緊閥、隔膜閥)也可用于節(jié)流控制，但通常只能在有限的閥門(mén)口徑范圍內(nèi)適用。閘閥是以圓盤(pán)形閘板對(duì)圓形閥座口做橫切運(yùn)動(dòng)，它只有在接近關(guān)閉位置時(shí)，才能較好地控制流量，故通常不用于流量控制。根據(jù)加工要求，部分零部件需要做拋光處理，表面不能有加工毛刺等。</p><div

style="text-indent:25px">旋塞閥工作原理：旋塞閥是用帶通孔的塞體作為啟閉件的閥門(mén)，塞體隨閥桿轉(zhuǎn)動(dòng)，以實(shí)現(xiàn)啟閉動(dòng)作。旋塞閥作用旋塞閥較適于作為切斷和接通介質(zhì)以及分流適用，但是依據(jù)適用的性質(zhì)和密封面的耐沖蝕性，有時(shí)也可用于節(jié)流。旋塞閥普遍地應(yīng)用于油田開(kāi)采、輸送和精練設(shè)備中、石油化工、化工、煤氣、天然氣、液化石油氣、暖通行業(yè)和一般工業(yè)中。旋塞閥還適用于輸送含有懸浮物和顆粒的液體，直通式旋塞閥配合保溫措施后可以輸送含結(jié)晶體的物料。試壓方法旋塞閥進(jìn)行強(qiáng)度試驗(yàn)時(shí)，介質(zhì)從一端引入，封閉其余通路，將塞子依次旋轉(zhuǎn)到全開(kāi)的各工作位置進(jìn)行試驗(yàn)，閥體未發(fā)現(xiàn)滲漏為合格。密封性試驗(yàn)時(shí)，直通式旋塞應(yīng)保持腔內(nèi)與通路壓力相等，將塞子旋轉(zhuǎn)到關(guān)閉位置，從另一端進(jìn)行檢查，然后將塞子旋轉(zhuǎn)180°重復(fù)上述試驗(yàn)；三通式或四通式旋塞閥應(yīng)保持腔內(nèi)與通路一端壓力相等，將塞子依次旋轉(zhuǎn)到關(guān)閉位置，壓力從直角端引入，從其他端同時(shí)進(jìn)行檢查。閥門(mén)注脂時(shí)，常忽略注脂效果問(wèn)題。注脂操作中壓力、注脂量、開(kāi)關(guān)位都正常。蘇州閥門(mén)廠家聯(lián)系方式</p><p
