style="font-size:16px;">球閥不適用于節(jié)流。當它處于半開位置時，通過球體與閥座間隙的流體速度非?？欤@會造成球體和閥座損壞，導致閥門內(nèi)漏，使閥門無法密封，這一點與旋塞閥非常相似。同樣地，球閥也不能應(yīng)用于高溫條件，因為在高溫下球閥的閥座會受熱發(fā)生塑性變形，使球體與閥座間產(chǎn)生空隙，導致內(nèi)漏。球閥的一大優(yōu)點是閥門全開時通過閥門的流體壓降很小，幾乎不受阻礙。球閥可以分為文丘里閥、縮徑球閥和全通徑球閥三種，其中全通徑球閥的流道尺寸與管道內(nèi)徑相同，通過閥門的流體壓降非常小。球閥結(jié)構(gòu)簡單，價格也較為低廉，維修費用低且無需潤滑。球閥還有一個優(yōu)點是球體對閥座的密封非常好，通常不會發(fā)生內(nèi)漏。球閥頂部與閥桿的連接處通常是矩形的，這可以讓我們在不造成球體變形的情況下施加較大的力矩，對閥門的開閉進行控制。</span> </p><p> <span style="font-size:16px;">如果想要購買鍛鋼球閥，在購買鍛鋼球閥的時候我們還需要注意的就是查看一下樣本的質(zhì)量，相信在此之前我們曾經(jīng)接觸過許多同類型的產(chǎn)品，所以我們應(yīng)當了解一下樣本質(zhì)量的高低，但是有一點是需要大家注意的，那就是樣本好并產(chǎn)品好，樣本往往都是一些價格實惠價值理想的**產(chǎn)品，批量產(chǎn)品注定比樣本產(chǎn)品的質(zhì)量要稍稍低一點點。我們在選擇鍛鋼球閥的時候，基本的注意事項還是非常多的，不過我們還是應(yīng)當把握一點，那就是產(chǎn)品所具備的性價比，一般來說只要這款產(chǎn)品的性價比不存在任何的問題，那么也就意味著它可以漸漸走進我們的內(nèi)心深處，只要購買的產(chǎn)品符合自己的要求，而且可以讓我們使用很長時間，那么一切都不是問題，我們完全可以放心的購買它。</span>

style="font-size:16px;">氣動球閥的強度試驗應(yīng)在球體半開狀態(tài)下進行。①浮動式球閥密封性試驗：將閥處于半開狀態(tài)，一端引入試驗介質(zhì)，另一端封閉；將球體轉(zhuǎn)動幾次，閥門處于關(guān)閉狀態(tài)時打開封閉端檢查，同時檢查填料和墊片處密封性能，不得有滲漏現(xiàn)象。然后從另一端引入試驗介質(zhì)，重復(fù)上述試驗。②固定式球閥密封性試驗：在試驗前將球體空載轉(zhuǎn)動幾次，固定式球閥處于關(guān)閉狀態(tài)，從一端引人試驗介質(zhì)至規(guī)定值；用壓力表檢查引入端密封性能，使用壓力表精度0．5～1級，量程為試驗壓力的1．6倍。在規(guī)定時問內(nèi)，沒有降壓現(xiàn)象為合格；再從另一端引入試驗介質(zhì)，重復(fù)上述試驗。然后，將閥門處于半開狀態(tài)，兩端封閉，內(nèi)腔充滿介質(zhì)，在試驗壓力下檢查填料和墊片處，不得有滲漏。③三通球閥應(yīng)在各個位置上進行密封性試驗。</span>

style="font-size:16px;">當球閥密封不良時是容易被磨損和沖刷的，在一些極端的工況條件下，球閥的泄漏甚至會在一、兩個小時就導致閥體因為磨損而穿孔。對于密封性能良好的球閥，在閥門剛剛開啟的瞬間是容易被磨損的。此時，閥座與球體是較早脫開的部位，由于此處壓差很大，流速很高，因此很容易被磨損。為了解決固體顆粒介質(zhì)對球閥的磨損和沖刷問題，可以通過以下措施來減緩球閥的磨損：1、提高球閥的啟閉速度可以有效地減少閥門的磨損，尤其對于開關(guān)頻繁的球閥。2、介質(zhì)對閥門的磨損也會同時減小。3、設(shè)計時適當考慮增大球閥球體的直徑，使球體的密封部位不容易被磨損，即使球閥在使用過程中出現(xiàn)了磨損，也不會影響閥門的密封性能。4、在球閥球體和閥座容易被磨損的部位噴焊耐磨材料。5、在球閥的通道部位增加耐磨</span><span
