style="font-size:16px;">當(dāng)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?xí)谝弧蓚€小時就導(dǎo)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(dāng)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 style="font-size:16px;">襯套，以增強球閥的抗磨損能力。</span> </p><p> <span style="font-size:16px;">球閥的性能原理①球閥性能出色，擁有流體阻力小(全通徑流道閥體阻力系數(shù)幾乎與管道相同、不會造成壓力損失)。②結(jié)構(gòu)簡約，閥體對稱、體積小、可雙向流動、雙向密封。③密封可靠(尤其是閥座密封面采用非金屬材料時)④操作方便、啟閉迅速、轉(zhuǎn)動90度即可完成閥門的啟閉，便于遠(yuǎn)距離控制。⑤維修方便，閥座密封圈一般都是活動的，拆換方便，如果采用上裝式結(jié)構(gòu)，可在線更換。⑥閥門在全開或者全關(guān)位置，密封副與介質(zhì)完全隔離，高速通過的介質(zhì)不會沖蝕密封副。⑦球體在啟閉時是旋轉(zhuǎn)擦拭的過程，所以多數(shù)結(jié)構(gòu)的球閥可以用于帶懸浮固體顆粒的介質(zhì)，選用合適的耐磨的閥座密封材料，也可用于粉狀介質(zhì)。⑧直通式球閥用作切斷用，使用***、三通、四通等球閥用于分配介質(zhì)和改變介質(zhì)流向、V型可做節(jié)流用。⑨全通徑球閥全開式易于清掃球通過清掃管線，在石油，天然氣管道中***使用。⑩適用范圍廣、工作壓力從真空至高壓，公稱直徑DN8~3000，工作溫度為-254~815攝氏度。</span> 球閥結(jié)構(gòu)簡單，相對體積小，重量輕，便于維修。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="海北州球閥銷售電話,球閥"

style="font-size:16px;">為了滿足高溫、高壓、強沖蝕、長壽命等工業(yè)應(yīng)用的使用要求，近十幾年來，金屬密封球閥得到了很大的發(fā)展。尤其在工業(yè)發(fā)達的國家，如美國、意大利、德國、西班牙、荷蘭等，對球閥的結(jié)構(gòu)不斷改進，出現(xiàn)全焊接閥體直埋式球閥、升降式球閥、使球閥在長輸管線、煉油裝置等工業(yè)領(lǐng)域的應(yīng)用，出現(xiàn)了大口徑（3050mm）、高壓力（70MPa）、寬溫度范圍（-196~815℃）的球閥，從而使球閥的技術(shù)達到一個全新的水平。球閥是由旋塞閥演變而來，它的啟閉件是一個球體，利用球體繞閥桿的軸線旋轉(zhuǎn)90°實現(xiàn)開啟和關(guān)閉的目的。球閥在管道上主要用于切斷、分配和改變介質(zhì)流動方向，設(shè)計成V形開口的球閥還具有良好的流量調(diào)節(jié)功能。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。在各行業(yè)得到***的應(yīng)用。球閥閥體可以是</span><span style="font-size:16px;">整體的，也可以是組合式的。</span> 在要求具有調(diào)節(jié)性能時，需選用帶Ｖ形開口的**結(jié)構(gòu)的球閥。海北州球閥銷售電話</p><p style="text-indent:25px">支管，選用法蘭連接、焊接連接，全通經(jīng)或縮徑的球閥。海北州球閥銷售電話</p><p> <span style="font-size:16px;">球閥是由閥體和閥座構(gòu)成，雙倍運動閥座是當(dāng)中腔壓力大于出口壓力時，使閥座壓緊球體，密封圈產(chǎn)生彈塑性變形實現(xiàn)密封。該閥使用時，一旦上游密封意外失效產(chǎn)生泄漏，下游閥座實現(xiàn)密封。雙級密封式閥座對于承受較大密封力的采用橡膠和塑料組合密封結(jié)構(gòu)，橡膠主要起密封作用，塑料起支承和輔助密封雙重作用。內(nèi)調(diào)節(jié)式閥座是閥座與球體之間的密封比壓靠內(nèi)調(diào)整螺母調(diào)節(jié)，其優(yōu)點是沒有向外的泄漏點。外調(diào)節(jié)式閥座是閥座與球體之間的密封比壓靠外部調(diào)節(jié)螺塞壓緊楔塊使伸縮套產(chǎn)生位移進行調(diào)整。波紋管式閥座一般采用電子束焊或氬弧焊與閥座和導(dǎo)向套相連。設(shè)計時，應(yīng)保證閥座密封中心小于波紋管中徑，此結(jié)構(gòu)具有密封性可靠，彈性補償范圍大，三維空間靈活的特點。</span>
