style="font-size:16px;">球閥球體型式(1).浮動球與固定球結構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，因此具有結構簡單，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，但是結構復雜，工藝繁瑣，價格高。固定球的幾種結構型式和性能：①進口端密封：閥門關閉時填料和大部分閥體不受內壓，缺點是閥體轉矩大且閥桿軸承受壓力大。②出口端密封：如果進口端密封失敗可以使用出口端密封從而提高閥門密封可靠性，減小球體支撐軸的載荷，適用于高壓工況，但是流通截面積減少且關閉時內腔都處于介質壓力作用下。③前后雙密封：兩閥座前后端**切斷，關閉時進出口端同時受壓，閥門中腔和兩端通道可以被相互切斷，適用于高要求工況，可以通過泄壓閥沖洗閥體內部沉積物，但是中腔有介質且應設置防止異常升壓裝置。④油封式：在密封面間壓注特制的潤滑油，形成一層油膜，增強密封性能且減小扭矩摩擦。但是結構復雜。⑤軌道式球閥：閥桿上有導軌和導向銷的相互作用，但閥座結構單向密封，適用于惡劣</span><span style="font-size:16px;">工況，壽命長但是加工成本太高。</span> </p><p> <span style="font-size:16px;">閥門的特性一般有兩種，使用特性和結構特性。使用特性：它確定了閥門的主要使用性能和使用范圍，屬于閥門使用特性的有：閥門的類別(閉路閥門、調節(jié)閥門、安全閥門等)；產(chǎn)品類型(閘閥、截止閥、蝶閥、球閥等)；閥門主要零件(閥體、閥蓋、閥桿、閥瓣、密封面)的材料；閥門傳動方式等。結構特性：它確定了閥門的安裝、維修、保養(yǎng)等方法的一些結構特性，屬于結構特性的有：閥門的結構長度和總體高度、與管道的連接形式(法蘭連接、螺紋連接、夾箍連接、外螺紋連接、焊接端連接等)；密封面的形式(鑲圈、螺紋圈、堆焊、噴焊、閥體本體)；閥桿結構形</span><span style="font-size:16px;">式(旋轉桿、升降桿)等。閥門的使用特性和結構特性在選購的時候一定要注意，不然會對以后的使用過程有影響。</span> 按閥體流道直徑分類：全通徑式、縮徑式。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

style="font-size:16px;">球閥的球體是浮動的，在介質壓力作用下，球體能產(chǎn)生一定的位移并緊壓在出口端的密封面上，保證出口端密封。浮動球球閥的結構簡單，密封性好，但球體承受工作介質的載荷全部傳給了出口密封圈，因此要考慮密封圈材料能否經(jīng)受得住球體介質的工作載荷。這種結構，常用于中低壓球閥。球閥的球體是固定的，受壓后不產(chǎn)生移動。固定球球閥都帶有浮動閥座，受介質壓力后，閥座產(chǎn)生移動，使密封圈緊壓在球體上，以保證密封。通常在與球體的上、下軸上裝有軸承，操作扭距小，適用于高壓和大口徑的閥門。為了減少球閥的操作扭矩和增加密封的可靠程度，近年來又出現(xiàn)了油封球閥，既在密封面間壓注特制的潤滑油，以形成一層油膜，即增強了密封性，又減少了操作扭矩，更適用高壓大口徑的球閥。</span> 球閥通常用橡膠、尼龍和聚四氟乙烯作為閥座密封圈材料。崇信焊接球閥哪個好</p><p style="text-indent:25px">球閥也適用于輕型結構、低壓截止（壓差?。?、腐蝕性介質的管路系統(tǒng)中。崇信焊接球閥哪個好</p><p> <span style="font-size:16px;">保溫球閥優(yōu)點1．流體阻力小，其阻力系數(shù)與同長度的管段相等。2．結構簡單、體積小、重量輕。3．緊密可靠，目前球閥的密封面材料使用塑料、密封性好，在真空系統(tǒng)中也已使用。4．操作方便，開閉迅速，從全開到全關只要旋轉90°，便于遠距離的控制。5．維修方便，球閥結構簡單，密封圈一般都是活動的，拆卸更換都比較方便。6．在全開或全閉時，球體和閥座的密封面與介質隔離，介質通過時，不會引起閥門密封面的侵蝕。7．適用范圍廣，通徑從小到幾毫米，大到幾米，從高真空至高壓力都可應用。球旋轉90度時，在進、出口處應全部呈現(xiàn)球面，從而截斷流動。保溫球閥是一種比較新型的球閥類別，它有著自身結構所獨有的一些優(yōu)越性，如開關無摩擦，密封不易磨損，啟閉力矩小。這樣可減小所配執(zhí)行器的規(guī)格。配以多回轉電動執(zhí)行機構，可實現(xiàn)對介質的調節(jié)和嚴密切斷。***適用于石油、化工、城市給排水等要求嚴格切斷的工況。</span>
