style="font-size:16px;">球閥問世于20世紀(jì)50年代，隨著科學(xué)技術(shù)的飛速發(fā)展，生產(chǎn)工藝及產(chǎn)品結(jié)構(gòu)的不斷改進(jìn)，在短短的50年時(shí)間里，已迅速發(fā)展成為一種主要的閥類。在西方工業(yè)發(fā)達(dá)的國家，球閥的使用正在逐年不斷的上升。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。球閥適宜做開關(guān)、切斷閥使用。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。球閥的截止作用是靠金屬球體在介質(zhì)的作用下，于塑料閥座之間相互壓緊來完成的（浮動(dòng)球球閥</span><span style="font-size:16px;">）。閥座密封圈在一定的接觸壓力作用下，局部地區(qū)發(fā)生彈塑變形。這一變形可以補(bǔ)償球體的制造精度和表面粗糙度，保證球閥的密封性能。</span> </p><p> <span style="font-size:16px;">對于球閥的選擇有許多人關(guān)注的就是它的運(yùn)輸過程是否便捷，倘若運(yùn)輸起來非常復(fù)雜，同時(shí)還需要占用我們比較多的時(shí)間和精力，那么這款產(chǎn)品在出售的時(shí)候也容易被人們所忽略，但事實(shí)證明這款產(chǎn)品是可以被我們隨意更換的，如果我們需要進(jìn)行環(huán)境的改變和地理位置的變動(dòng)，那么這款產(chǎn)品也可以在輕而易舉的操縱之下完成，所以我們不需要擔(dān)心。經(jīng)過一番了解之后，我們才發(fā)現(xiàn)，原來電動(dòng)切斷球閥還具備著另外的一大特點(diǎn)，那就是是切換迅速。也許我們對于其內(nèi)部擁有著更高的要求，需要它在各種模式之間來回進(jìn)行切換，那么也是沒有任何問題的，因?yàn)檫@款產(chǎn)品在切換之后，幾乎不會(huì)產(chǎn)生任何的負(fù)面影響和安全隱患性問題，同時(shí)來回切換的過程還可以變得非常簡潔，非常迅速。</span>
