目前，液壓系統(tǒng)中普遍使用的各種液壓換向閥中，均存在著閥芯卡緊現(xiàn)象。其中有液壓卡緊，也有機(jī)械卡緊。為解決液壓卡緊，國內(nèi)外都在設(shè)計中采用閥芯外工作表面加工若干個平衡槽的辦法，其效果很好。對于機(jī)械卡緊也都制定了一些相應(yīng)的技術(shù)規(guī)范來限制其配合間隙和偏心量等主要影響因素。但盡管這樣，卡緊現(xiàn)象仍時有發(fā)生，下面就卡緊產(chǎn)生的原因和解決辦法作詳細(xì)討論。1、產(chǎn)生卡緊的原因，即液體在高壓下通過偏心環(huán)狀錐形間隙，并且沿液體流動方向縫隙是逐漸擴(kuò)大的，這時就會產(chǎn)生通常所說的液壓卡緊現(xiàn)象。1)閥芯因加工誤差而帶有倒錐(錐體大端朝向高壓腔)，在閥芯與閥孔中心線平行且不重合時，閥芯受到徑向不平衡力的作用。使閥芯和閥孔的偏心矩越來越大，直到兩者表面接觸而發(fā)生卡緊現(xiàn)象。此時，徑向不平衡力達(dá)到比較大值。2)閥芯無幾何形狀誤差，但是由于裝配誤差使閥芯在閥孔中歪斜放置，或者顆粒狀污染物凝聚楔入閥孔與閥芯的間隙，使閥芯在孔中偏斜放置，產(chǎn)生很大的徑向不平衡力及轉(zhuǎn)矩。3)在加工或工序間轉(zhuǎn)移過程中，將閥芯碰傷，有局部凸起及殘留毛刺。這時凸起部分背后的液壓流將造成較大的壓降，產(chǎn)生一個使凸起部分壓向閥孔的力矩。這也是液壓卡緊的一種成因。</p><p>

球閥只需要用旋轉(zhuǎn)90度的操作和很小的轉(zhuǎn)動力矩就能關(guān)閉嚴(yán)密。完全平等的閥體內(nèi)腔為介質(zhì)提供了阻力很小、直通的流道。通常認(rèn)為球閥**適宜直接做開閉使用，但近來的發(fā)展已將球閥設(shè)計成使它具有節(jié)流和控制流量之用。球閥的主要特點是本身結(jié)構(gòu)緊湊，易于操作和維修，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、過氧化氫、甲烷和乙烯等。球閥閥體可以是整體的，也可以是組合式的。球閥的工作原理和作用球閥的工作原理是靠旋轉(zhuǎn)閥芯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。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(dá)到開啟、關(guān)閉的一種閥門。球閥在管路中主要用來做切斷、分配和改變介質(zhì)的流動方向。球閥是近年來被普遍采用的一種新型閥門，它具有以下優(yōu)點：1、流體阻力小，其阻力系數(shù)與同長度的管段相等。2、結(jié)構(gòu)簡單、體積小、重量輕。3、緊密可靠，目前球閥的密封面材料普遍使用塑料、密封性好，在真空系統(tǒng)中也已普遍使用。4、操作方便，開閉迅速。
