液压接头拧紧扭矩汇总液压管接头大部分都是螺纹连接，管接头主要起到连接和密封的作用，只有适当的拧紧才能保证可靠的连接和密封，那么不同的液压接头应该施加多大的拧紧扭矩呢？液压接头的拧紧扭矩和接头的密封形式和螺纹摩擦系数决定的，在液压接头装配过程中，首先需要参考的是接头厂家提供的拧紧扭矩进行装配，如果厂家没有提供安装扭矩，可以参照如下表中，不同管接头的拧紧扭矩进行组装。O型圈密封的管接头拧紧扭矩O型圈密封管接头拧紧扭矩表螺柱端端面密封端螺纹规格扭矩N+mref管外径mm總纹规格螺纹规格+10%M12K1,5359/16-18UNF25M14K1,545B5/8-18UNF30M16x1,5551011/16-16UN40M1Sx1,5701213/16-16UN55M22X1,5WO161-14UNS60M27x217020137ie-12UN@0M30x22352215/1^12UN115M33K2310為1r/16-12UN125M423303011V16-12UN170M48x24203S2-12UN2001.卡套式管接头拧紧扭矩螺母卡套式管接头分轻型（L）和重型（S），风别用L和S表示，下表为卡套式管接头的拧紧扭矩。螺纹规格管外径(mm)扭矩Nm+10螺纹规格管外径(mm)扭矩Nin+10%M12X1.56L25M14X1.56S30M14X1.58L35M16X1.58S40M16X1.510L45M18X1.51OS60M1SX1.512L60M2OX1.512S75M22X1.515L95M24X1.516S130M26X1.518L140M30X22OS220M30X222L200M36X225S330M36X228L260M45X230S460M45X235L420M52X238S620M52X242L5802.公制旋转螺母接头公制旋转螺母接头也分轻型和重型，轻型用L表示，重型用S表示。轻型和重型公制旋转螺母的管接头拧紧扭矩如下表：AN螺纹规格管外径公称扭矩min.-max.M12x1.506L1615-17M14x1.508L1615-17M16x1.510L2625-28M18x1.512L3735-39M22x1.515L4745-50M26x1.518L8985-94M30x222L116110-121M36x228L137130-143M45x235L226215-237M52x242L347330-363M14x1.506S2625-28M16x1.508S4240-44M18x1.510S「5350-55M20x1.512S6360-66M22x1.514S7975-83M24x1.516S8480-88M30x220S126120-132M36x225S179170-187M42x2SOS263250-275M52x238S368350-385尺寸这里数字是指，1/16英寸的倍数i曹螺纹公称扭矩min.-max.G1/4-42015-25G3/8-6342(-41G1/2-86042-76G5/8-W剪44-94G3/4-1211b95-135G1-16140115-165G1-1/4-20210140-280G1-1/2-24290215-365G2-32400300-500JIC37°美制螺纹旋转螺母接头t尺寸螺母拧紧美制螺纹(FFWR)7/16-20-42181/2-20-5|2239/16-18-61-1/2303/4-16-y1-1/25了7/8-14-101-1/2811.1/16-12-121-1/41141.5/16-12-16116DL5/8-12-2012281.7/8-12•2412652J/2-123213603.SAE法兰连接管接头拧紧扭矩SAE法兰连接管接头分为高压型（6000PSI）和低压型（3000PSI）,每种又可分成分片式法兰和整体法兰，连接螺栓也可分成公制螺栓和美制螺栓。这里仅列出分片式法兰公制螺栓连接时，螺栓的拧紧扭矩。（C0DE61）法兰接头螺栓拧紧扭矩公称尺寸DNa汁1+0-1,5max.0型圈尺寸平垫圈1型-公制螺栓性能等级9血栓称径蟒公直螺栓长度*2螺纹长度螺栓扭矩Nm-10%-01313.013,0210M8M32516321919,219,2214M10M103013702525.625,6219M10M1O3013703232.032.0222M10cM1O301S703838,238,2225M12M1235231305151,051.0228M12M1235231306463,563,5232M12M1240231307675,276,2237M16M16503029589E9.089.0241M16M165030295102101,6101,6245M16M165030295127127,0127,0253M16M165530255CODE62公称尺寸DNS納+0-1.5艇max.0型圈尺寸平垫圏(recom*mended)1型-公制螺栓性能等级10.9栓度枷螺长螺纹长度螺栓扭矩Nm4-10%-01313,013,0210M6M63018321919.219,2214M10M103518702525,625.6219M12cM1245231303232.032,0222M12M124523130SB3fi,238.2225M16M1655272955151,051,0228M20M207035550&463,063232M24M2430505507676,075237M3QM309060650
