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;">由于球閥在啟閉過程中有擦拭性，所以可用于帶懸浮固體顆粒的介質(zhì)中。球閥流體阻力小，無振動(dòng)，噪聲小。球閥在管道上主要用于切斷、分配和改變介質(zhì)流動(dòng)方向，設(shè)計(jì)成V形開口的球閥還具有良好的流量調(diào)節(jié)功能。球閥不*結(jié)構(gòu)簡(jiǎn)單、密封性能好，而且在一定的公稱通徑范圍內(nèi)體積較小、重量輕、材料耗用少、安裝尺寸小，并且驅(qū)動(dòng)力矩小，操作簡(jiǎn)便、易實(shí)現(xiàn)快速啟閉，是近十幾年來發(fā)展**快的閥門品種之一。特別是在美、日、德、法、意、西、英等工業(yè)發(fā)達(dá)國(guó)家，球閥的使用品種和數(shù)量仍在繼續(xù)擴(kuò)大，并向高溫、高壓、大口經(jīng)、高密封性、長(zhǎng)壽命、優(yōu)良的調(diào)節(jié)性能以及一閥多功能方向發(fā)展，其可靠性及其他性能指標(biāo)均達(dá)到較高水平，并已部分取代閘閥、截止閥、節(jié)流閥。隨著球閥的技術(shù)進(jìn)步，在可以預(yù)見的短時(shí)見內(nèi)，特別是在石油天然氣管線上、煉油裂解裝置上以及核工業(yè)上將有更的應(yīng)用。此外，在其他工業(yè)中的大中型口徑、中低壓力領(lǐng)域，球閥也將會(huì)成為主導(dǎo)的閥門類型之一。球閥的工作原理是靠旋轉(zhuǎn)閥桿來使閥門暢通或閉塞。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(jiǎn)單，維修方便，密封面與球面常在閉合狀態(tài)，</span><span
