style="font-size:16px;">球閥的種類，你了解多少？球閥分類方式很多，以下主要介紹四種分類方式。球閥一般是即開即關(guān)使用，密封性也沒有針閥，膜片閥好！如果用在高壓易燃易爆氣體上，氣體流速太快，有一定的風(fēng)險系數(shù)，球閥通徑比較大，一般和口徑相同，所以截流比較小，通過性比較好！球閥按照操作原理一般分為手動，氣動，電動！(1).按球體結(jié)構(gòu)型式分類：浮動球式、固定球式。主要產(chǎn)品例如：法蘭浮動球閥、固定球兩片式球閥、固定球軟密封球閥、襯氟球閥、固定球不銹鋼高溫球閥等。(2).按球閥流通型式分類：直通式、三通式、四通式、五通式。主要產(chǎn)品例如：直通一片式球閥、三通法蘭球閥等。(3).按閥體裝配形式分類：一體式、二體式、三體式、上裝式。主要產(chǎn)品例如：兩體襯氟球閥、三體不銹鋼球閥、上裝式球閥等。(4).按閥體</span><span style="font-size:16px;">流道直徑分類：全通徑式、縮徑式。主要產(chǎn)品例如：全通徑法蘭球閥、縮徑式球閥等。</span> </p><p> <span 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> 快速啟閉閥門時，操作無沖擊;</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="張掖球閥聯(lián)系人電,球閥" src="https://tyunfile.71360.com/UploadFile/gscyhwz/637318945336777343/4499907.png"></div><p> <span style="font-size:16px;">球閥適用場合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（浮動球球閥）。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。這一變形可以補償球體的制造精度和表面粗糙度，保證球閥的密封性能。又由于球閥的閥座密封圈通常采用塑料制成，故在選擇球閥的結(jié)構(gòu)和性能上，要考慮球閥的耐火和防火，特別是在石油、化工、冶金等部門，在易燃、易爆介質(zhì)的設(shè)備和管路系統(tǒng)中使用球閥，更應(yīng)注意耐火和防火。通常，在雙位調(diào)節(jié)、密封性能嚴(yán)格、泥漿、磨損、縮口通道、啟閉動作迅速（1/4轉(zhuǎn)啟閉）、高壓截止（壓差大）、低噪聲、有氣穴和氣化現(xiàn)象、向大</span><span style="font-size:16px;">氣少量滲漏，操作力矩小、流體阻力小的管路系統(tǒng)中，推薦使用球閥。</span> 球閥的使用性能及優(yōu)點有哪些呢？張掖球閥聯(lián)系人電</p><p style="text-indent:25px">球閥也適用于輕型結(jié)構(gòu)、低壓截止（壓差小）、腐蝕性介質(zhì)的管路系統(tǒng)中。張掖球閥聯(lián)系人電</p><p> <span style="font-size:16px;">球閥球體型式(1).浮動球與固定球結(jié)構(gòu)型式和性能比較圖如圖所示。浮動球可以自由地在閥座中浮動，因此具有結(jié)構(gòu)簡單，重量輕等優(yōu)點，但是必須要有足夠的輕度來承受高的密封比壓、以及操作扭矩大、不適用高壓及大口徑閥門。固定球的閥球不會移動，整體渾然天成，因此扭矩小，密封性能好，適用大口徑高壓環(huán)境，但是結(jié)構(gòu)復(fù)雜，工藝繁瑣，價格高。2.閥體流道直徑型式全通徑式流道接近管道，流體壓力損失小，且便于清掃球清掃?？s徑式的流道直徑小于公稱通徑，閥門整體結(jié)構(gòu)縮小，節(jié)省材料，環(huán)保節(jié)約。但是流道阻力會增加。球閥一般是即開即關(guān)使用，密封性也沒有針閥，膜片閥好！如果用在高壓易燃易爆氣體上，氣體流速太快，有一定的風(fēng)險系數(shù)，球閥通徑比較大，一般和口徑相同，所以截流比較小，通過性比較好！</span>
