style="font-size:16px;">高溫球閥的主要特點(diǎn)是本身結(jié)構(gòu)緊湊，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，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，在各行業(yè)得到的應(yīng)用。球閥閥體可以是整體的，也可以是組合式的。高溫球閥它具有旋轉(zhuǎn)90度的動(dòng)作，旋塞體為球體，有圓形通孔或通道通過其軸線。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，但近來的發(fā)展已將球閥設(shè)計(jì)成使它具有節(jié)流和控制流量之用，如V型球閥。球閥不*結(jié)構(gòu)簡單、密封性能好，而且在一定的公稱通徑范圍內(nèi)體積較小、重量</span><span

style="font-size:16px;">球閥是一種利用球體繞閥桿的軸線旋轉(zhuǎn)90°實(shí)現(xiàn)開啟和關(guān)閉的目的閥門裝置。在具體的閥門介紹過程中，螺桿風(fēng)機(jī)廠家已經(jīng)單獨(dú)介紹過止回閥、蝶閥、安全閥以及調(diào)節(jié)閥等，***我們再來了解下常見的球閥。球閥由旋塞演變而來，啟閉件是一個(gè)球體，因其結(jié)構(gòu)簡單、密封性好，而且在一定的公稱通徑范圍內(nèi)體積較小、重量輕、材料損耗少，所以是一種實(shí)用性很強(qiáng)、使用很的閥門品種，用于切斷或改變介質(zhì)流量。其公稱通徑從8mm——1200mm，公稱壓力從真空到42MPa，工作溫度從-204℃到815℃。密封性能好；由于硬密封球閥的密封是采用人工研磨，直到閥芯與密封圈完全吻合才能使用。所以他的密封性能是可靠的。開關(guān)輕；由于硬密封球閥的密封圈底部采用彈簧使密封圈與閥芯緊緊抱在一起。</span> </p><p> <span style="font-size:16px;">球閥隨著科學(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40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。在我國，球閥的應(yīng)用在石油煉制、長輸管線、化工、造紙、制利、電力、市政、鋼鐵等行業(yè)，在國民經(jīng)濟(jì)中占有舉足輕重的地位。它具有旋轉(zhuǎn)90度的動(dòng)作，旋塞體為球體，有圓形通孔或通道通過其軸線。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，V型球閥。電動(dòng)閥門除應(yīng)注意管道參數(shù)外，尚應(yīng)特別注意其使用的環(huán)境條件，由于電動(dòng)閥門中的電動(dòng)裝置是一機(jī)電設(shè)備，其使用狀態(tài)受其使用環(huán)境影響很大。通常狀態(tài)下，電動(dòng)球閥、蝶閥在以下環(huán)境使用特點(diǎn)：一、耐磨；由于硬密封球閥的閥芯是合金鋼噴焊，三片式球閥密封圈是合金鋼堆焊，所以硬密封球閥在開關(guān)時(shí)不會(huì)產(chǎn)生太大的磨損。。</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 style="font-size:16px;">成機(jī)械傳動(dòng)，還可以由電力、液力、氣力來操作。球閥與旋塞閥一樣，可以制成直角、三通、四通等形式。</span> 球閥屬于固定球閥，也是單閥座密封球閥。甘谷焊接球閥費(fèi)用</p><p
