style="font-size:16px;">由于球閥通常用橡膠、尼龍和聚四氟乙烯作為閥座密封圈材料，因此它的使用溫度受到閥座密封圈材料的限制。球閥主要的閥座密封圈材料就是聚四氟乙烯（PTFE），它對(duì)幾乎所有的化學(xué)物質(zhì)都是惰性的，且具有摩擦系數(shù)小、性能穩(wěn)定、不易老化、溫度適用范圍廣和密封性能優(yōu)良的綜合性特點(diǎn)。但聚四氟乙烯的物理特性，包括較高的膨脹系數(shù)，對(duì)冷流的敏感性和不良的熱傳導(dǎo)性，要求閥座密封的設(shè)計(jì)必須圍繞這些特性進(jìn)行。閥座密封的塑性材料也包括填充聚四氟乙烯、尼龍和其他許多材料。但是，當(dāng)密封材料變硬時(shí)，密封的可靠性就要受到破壞，特別是在低壓差的情況下。此外，像丁青橡膠這樣的合成橡膠也可用作閥座密封材料，但它所適用的介質(zhì)和使用的溫度范圍藥受到限制。另外，如果介質(zhì)不潤(rùn)滑，使用合成橡膠容易卡住球</span><span

style="font-size:16px;">電動(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(guò)其軸線。電動(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(jiǎn)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。球閥在管路中主要用來(lái)做電動(dòng)球閥切斷、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。電動(dòng)球閥適宜做開(kāi)關(guān)、切斷閥使用，但近來(lái)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。適用于水、溶劑、酸和天然氣等一般工作介質(zhì)，而且還適用于工作條件惡劣的介質(zhì)，如氧氣、過(guò)氧化氫、甲烷和乙烯等，在各行業(yè)得到的應(yīng)用。球閥閥體可以是整體的，也可以是組合式的。操作靈活：采用具有小摩擦系數(shù)和良好自潤(rùn)滑性的閥座和閥桿軸承，地減少</span><span
