民樂球閥多少錢快速啟閉閥門時(shí)，操作無沖擊;</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="民樂球閥多少錢,球閥"

style="font-size:16px;">球閥是指啟閉件(球體)由閥桿帶動(dòng)，并繞閥桿的軸線作旋轉(zhuǎn)運(yùn)動(dòng)的閥門。球閥的優(yōu)點(diǎn)是具有比較低的流阻、驅(qū)動(dòng)力矩小，操作簡(jiǎn)便，可實(shí)現(xiàn)快速啟閉、密封性能好、結(jié)構(gòu)緊湊，質(zhì)量輕、閥體對(duì)稱，尤其是焊接閥體結(jié)構(gòu)，能很好的承受來自管道的應(yīng)力、使用壽命長。球閥可分為浮動(dòng)球球閥和固定球球閥兩類。所謂浮動(dòng)球球閥的球體不帶固定軸，球體是浮動(dòng)的，由兩個(gè)閥座支承。分為一體式浮動(dòng)球球閥和兩體式浮動(dòng)球球閥;而固定球球閥的球體有固定軸，球體是固定的，由兩段與球體連接在一起的固定軸與閥體上的滑動(dòng)軸承支承。固定球球閥分為兩體式固定球球閥、三體式固定球球閥、上裝式固定球球閥和全焊接式固定球球閥。球閥是在灰渣管路中比較理想的啟閉裝置，其上密封好壞直接影響閥門的質(zhì)量和使用壽命。過去采用O形橡膠密封結(jié)構(gòu)形式，即在軸上加工出的環(huán)形槽內(nèi)放入O形密封圈，然后將其裝配進(jìn)套類零件上加工出的孔內(nèi)，形成軸與孔的密封，這種結(jié)構(gòu)的密封性能取決于設(shè)計(jì)時(shí)的過盈量，即O形密封圈的壓縮量和孔、軸零件的加工精度。過盈量太小，密封性能差，過盈量太大，裝配時(shí)容易擠壞O形密封圈，使密封失效。</span> </p><p> <span style="font-size:16px;">球閥的適用領(lǐng)域球閥也適用于輕型結(jié)構(gòu)、低壓截止（壓差?。?、腐蝕性介質(zhì)的管路系統(tǒng)中。在低溫（深冷）裝置和管路系統(tǒng)中也可選用球閥。在冶金行業(yè)的氧氣管路系統(tǒng)中，需使用經(jīng)過嚴(yán)格脫脂處理的球閥。在輸油管線和輸氣管線中的主管線需埋設(shè)在地下時(shí)，需使用全通徑焊接式球閥。在要求具有調(diào)節(jié)性能時(shí)，需選用帶Ｖ形開口的**結(jié)構(gòu)的球閥。在石油、石油化工、化工、電力、城市建設(shè)中，工作溫度在200℃以上的管路系統(tǒng)可選用金屬對(duì)金屬密封的球閥。球閥適用原則石油、天然氣的輸送主管線、需要清掃管線的，又需埋設(shè)在地下的，選用全通經(jīng)、全焊接結(jié)構(gòu)的球閥；埋設(shè)在地上的，選擇全通經(jīng)焊接連接或法蘭連接的球閥；支管，選用法蘭連接、焊接連接，全通經(jīng)或縮徑的球閥。</span>
