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，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類型的閥門，只有它的關(guān)閉件是個球體，球體繞閥體中心線作旋轉(zhuǎn)來達到開啟、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">閥門與其他機械產(chǎn)品一樣，也是需要維護保養(yǎng)的。這項工作做的好，可以延長閥門的使用壽命，下文將介紹閥門的維護保養(yǎng)，保管維護：保管維護的目的，是不讓閥門在保管中損壞，或降低質(zhì)量。而實際上，保管不當(dāng)是閥門損壞的重要原因之一。閥門保管，應(yīng)該井井有條，小閥門放在貨架上，大閥門可在庫房地面上整齊排列，不能亂堆亂垛，不要讓法蘭連接面接觸地面。這不僅為了美觀，主要是保護閥門不致碰壞。由于保管和搬運不當(dāng)，手輪打碎，閥桿碰歪，手輪與閥桿的固定螺母松脫丟失等等，這些不必要的損失，應(yīng)該避免。對短期內(nèi)暫不使用的閥門，應(yīng)取出石棉填料，以免產(chǎn)生電化學(xué)腐蝕，損壞閥桿。對剛進庫的閥門，要進行檢查，如在運輸過程中進了雨水或污物，要擦試干凈，再予存放。閥門進出口要用蠟紙或塑料片封住，以防進去臟東西。對能在大氣中生銹的閥門加工面要涂防銹油，加以保護放置室外的閥門，必須蓋上油氈或苫布之類防雨、防塵物品。存放閥門的倉庫要保持清潔干燥。氣動閥門處于氣動控制系統(tǒng)的關(guān)鍵地位。上海單向氣動球閥供貨價格</p><p

style="text-indent:25px">氣動閥門分為:單作用和雙作用氣缸。單作用氣缸帶彈簧復(fù)位功能，所以價格較貴。彈簧復(fù)位功能的概念:閥門初始狀態(tài)是關(guān)閉的-俗稱“氣開式”，通氣后閥門開啟，如果突然氣源斷掉了，這時候彈簧復(fù)位功能就起作用了，彈簧復(fù)位會把閥門關(guān)閉掉。同理，如果閥門初始狀態(tài)是開啟的--俗稱“氣閉式”，通氣后閥門關(guān)閉，如果突然氣源斷掉了，這時候彈簧復(fù)位會把閥門打開。單作用氣缸，通常用在那些:強酸，強堿，帶有腐蝕性的液體介質(zhì)，或者有毒氣體。簡單說，就是不能泄露的介質(zhì)，如果泄露會造成傷亡事故的介質(zhì)。所以單作用氣缸比較貴。雙作用氣缸:閥門無論是開啟還是關(guān)閉都需要氣源。如果突然氣源斷掉，閥門就保持在那當(dāng)時的狀態(tài)下，氣源重新連接上以后閥門才能繼續(xù)工作。雙作用氣缸:在對泄露要求不高的工況下，可以選用雙作用氣缸。上海大口徑氣動球閥制造商</p><p
