style="font-size:16px;">球體通道為圓形，不縮徑的球體圓形通道與閥體圓形通道連接呈直管段，所以流阻非常小。根據(jù)不同工況，密封副可選擇金屬、合金、非金屬，密封性能好。球閥有體積小、啟閉迅速、操作方便、安全可靠、使用壽命長、適用范圍廣等優(yōu)點(diǎn)，部分取代了閘閥、截止閥、節(jié)流閥、多通道球閥可用來實(shí)現(xiàn)介質(zhì)分配與改變介質(zhì)流向。球閥是近年來發(fā)展很快的閥種之一，可以預(yù)見隨著球閥制造技術(shù)的進(jìn)步，將會(huì)得到更好的應(yīng)用。(1).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(huì)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(dòng)、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(shí))④操作方便、啟閉迅速、轉(zhuǎn)動(dòng)90度即可完成閥門的啟閉，便于遠(yuǎn)距離控制。⑤維修方</span><span style="font-size:16px;">便，閥座密封圈一般都是活動(dòng)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(huì)沖蝕密封副。</span><span style="font-size:16px;">⑦球體在啟閉時(shí)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。</span>

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;">鍛鋼全焊接球閥特點(diǎn)：1、閥體采用整體鍛件，確保不會(huì)存在沙眼等質(zhì)量問題2、鍛鋼材質(zhì)制造性能更加可靠，采用機(jī)械整體焊接無泄漏3、球體的加工精度非常精密操作輕便，可以根據(jù)客戶要求定制球體4、美標(biāo)鍛鋼全焊接球閥的產(chǎn)品具體尺寸，客戶可以提供圖紙根據(jù)客戶圖紙加工5、閥座也由鍛件組成，密封可選用尼龍、PPL、硬密封等，根據(jù)要求定制閥門的密封6、美標(biāo)鍛鋼全焊接球閥在選型正確，正常操作、維護(hù)使用的情況下，使用壽命比普通的都長，開關(guān)次數(shù)可以達(dá)到數(shù)萬次，使用壽命**長可以達(dá)20年以上。美標(biāo)鍛鋼全焊接球閥應(yīng)用領(lǐng)域：城市煤氣：特別是主管線、高壓力的管網(wǎng)中作為整個(gè)管道的主開關(guān)。集中供熱：大型供熱設(shè)備輸出管線、主干線、支線。熱交換機(jī)：管道及各回路啟閉，相對使用口徑較小。鋼鐵廠：各種流體管道、廢氣擇放管道、煤氣和熱力供應(yīng)管道等各種工業(yè)設(shè)備：各種熱處理管道、或者一些燃?xì)狻⒚簹夤镜墓芫€主管道或者壓力高管道。7、防靜電功能：在</span><span

style="font-size:16px;">固定球閥的特點(diǎn)1、雙阻塞與排放功能：固定球閥采用彈簧預(yù)緊浮動(dòng)閥座，無論閥門處于全開或全關(guān)狀態(tài)時(shí)，上下游側(cè)的閥座使流體阻斷，閥體中腔滯留物通過排放閥排泄。2、自動(dòng)泄壓功能：閥門體腔停留介質(zhì)溫度升高而引起異常升壓時(shí)，不需通過安全閥，而*靠閥座功能就可自動(dòng)泄壓，這對保證閥門在輸送液體介質(zhì)時(shí)的安全性非常重要。3、防火安全結(jié)構(gòu)：閥門都具備防火安全功能，其設(shè)計(jì)、制造均遵循API607和API6FA規(guī)范要求。固定球閥圖片固定球閥結(jié)構(gòu)圖固定球閥。閥座密封圈常用聚四氟乙烯制成，因?yàn)槠淠Σ烈驍?shù)小，耐腐蝕性能優(yōu)異，耐溫范圍寬。也可用聚三氟氯乙烯，它比前者耐腐蝕性能稍差，但機(jī)械強(qiáng)度高。橡膠密封性能很好，但耐壓、耐溫性能較差，只用于溫度不高的低壓管道。大型球閥，可以制</span><span
