QB型球型补偿器结构特征：球形补偿器（又称球形接头），主要依靠球体的角位移来吸收或补偿管道一个或多个方向上的横向位移，该补偿器应成对使用，单只球形补偿器没有补偿能力，可作管道万向接头使用。该补偿器具有补偿量大，无盲板力，对固定管架的作用力小，密封采用可注组合密封技术，实现长期可靠密封。主要技术参数：公称压力：1.0,1.6,2.5,4.0mpa公称通径ＤＮ径向最大尺寸球心距E(mm)转距（KNM)接口端口尺寸总长Ｌ（mm)2280重量1.0MPa1.6MPa2.5MPa4.0MPa1.0MPa1.6MPa2.5MPa4.0MPa法兰连接接管法兰接管法兰接管法兰接管法兰501801140.070.110.170.28￠59*3.5200182318.823.8232926651981520.140.230.360.58￠73*426026312733323938802251680.320.510.801.28￠89*4292374538464553541002601780.540.861.342.15￠108*4310566658687082831253002061.041.672.614.18￠133*43507787799195111121503752541.522.433.806.08￠159*4.54408599871011051251212004402362.153.455.398.63￠219*54351181371211411451761702505403154.226.7510.5516.88￠273*65842382622432712903303413006082756.3410.1515.8625.38￠325*66023313602383754054574703506853708.3113.3020.7833.25￠377*867050354651456961569672040078042010.83170.2327.0643.30￠426*875758464559666571582284045082543515.3424.5538.3661.38￠480*8822846911864965820917121750090033620.8133.3052.0383.25￠529*872896510459851111115013151408600105544826.2241.9565.55104.87￠630*89001345144913751640164718951943700130071031.785.0.8479.44127.10￠720*812901524155518862193800145083038.2661.2295.65153.05￠820*1014801700173520802465900163095045.2072.32113.05180.80￠920*101650187619102298270010001810110052.7484.38131.84210.95￠1020*101810205821002520294011001990135060.9197.46152.28243.65￠1120*10205023702425288012002170155069.78111.65174.45279.13￠1220*142280279527953280)
