style="text-indent:25px">球閥的密封形式及相關技術要求：球閥主密封結構的形式，密封材料的選擇等影響球閥密封性能和使用性能、可靠性的因素?，F(xiàn)在在球閥上主要采用彈性脹圈和聚四氛乙烯唇式密封座組成的組合型密封座的結構形式。球閥普遍應用于各種管路系統(tǒng)的快速切斷、改變介質流向和自動控制，可采用手動、電動或氣動等驅動方式。不銹鋼閥門的密封結構主要由三部分組成，其一為主、副閥體間的密封，由密封調整墊片實現(xiàn);其二為主閥體與閥桿間的密封，由標準“V”形填料或 0 形密封圈實現(xiàn)，組成球閥的外密封結構。</p><p style="text-indent:25px">球閥一般有縮徑和不縮徑通道兩種結構。無論那種結構，球閥的流阻系數(shù)都比較小。特別是所謂全流量型，即不縮徑的球閥，由于其通道直徑等于管道內徑，局部阻力損失只有同等長度管道的摩擦阻力，即在所有閥門中，這種球閥的流阻較小。在火箭發(fā)射及其試驗系統(tǒng)中，要求輸送管道的阻力越小越好。減少管路系統(tǒng)的阻力有兩個途徑:一是降低流體流速，為此需要增大管徑和閥門通徑，這對于管路系統(tǒng)的經濟性往往會產生不利的影響，特別對低溫輸送系統(tǒng)(液氫)是極為不利的。球閥只需要很小的轉動力矩就能關閉嚴密。</p><div

style="text-indent:25px">球閥預壓縮量的獲得與調整不再依靠密封調整墊片而由彈性元件來實現(xiàn)。帶彈性元件的密封座除可獲得必要的預壓縮量外，還可在彈性元件的彈性變形范圍內對預緊比壓進行補償，球閥的使用壽命相對較長。球閥的檢修步驟：球閥(以下簡稱球閥)檢修的一般程序用壓縮空氣吹掃球閥外表面。檢查并記下球閥上的標志。將球閥全部拆卸。用煤油清洗零件。檢查零件的缺陷：以水壓試驗檢查閥體強度;檢查閥座與閥體及關閉件與密封圈的配合情況，并進行嚴密性實驗;檢查閥桿及閥桿襯套的螺紋磨損情況;檢驗關閉件及閥體的密封圈;檢驗法蘭的接合面。薄型對夾球閥廠商</p><p
