burkert帶氣動(dòng)旋轉(zhuǎn)式執(zhí)行機(jī)構(gòu)氣動(dòng)球閥,BURKERT2658型氣動(dòng)球閥
burkert帶氣動(dòng)旋轉(zhuǎn)式執(zhí)行機(jī)構(gòu)氣動(dòng)球閥它具有旋轉(zhuǎn)90度的動(dòng)作，旋塞體為球體，有圓形通孔或通道通過其軸線。球閥在管路中主要用來做切斷、分配和改變介質(zhì)的流動(dòng)方向，它只需要用旋轉(zhuǎn)90度的操作和很小的轉(zhuǎn)動(dòng)力矩就能關(guān)閉嚴(yán)密。球閥zui適宜做開關(guān)、切斷閥使用，但近來的發(fā)展已將球閥設(shè)計(jì)成使它具有節(jié)流和控制流量之用，如V型球閥。 burkert帶氣動(dòng)旋轉(zhuǎn)式執(zhí)行機(jī)構(gòu)氣動(dòng)球閥的主要特點(diǎn)是本身結(jié)構(gòu)緊湊，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，易于操作和維修，適用于水、溶劑、酸和天然氣等般工作介質(zhì)，而且還適用于工作條件惡劣的介質(zhì)，如氧氣、過氧化氫、甲烷和乙烯等，在各得到廣泛的應(yīng)用。球閥閥體可以是整體的，也可以是組合式的。burkert帶氣動(dòng)旋轉(zhuǎn)式執(zhí)行機(jī)構(gòu)氣動(dòng)球閥的球體是彈性的。球體和閥座密封圈都采用金屬材料制造，密封比壓很大，依靠介質(zhì)本身的壓力已達(dá)不到密封的要求，必須施加外力。這種閥門適用于高溫高壓介質(zhì)。 BURKERT彈性球體是在球體內(nèi)壁的下端開條彈性槽，而獲得彈性。當(dāng)關(guān)閉通道時(shí)，用閥桿的楔形頭使球體漲開與閥座壓緊達(dá)到密封。
