Universal couplingConnection method 

        Universal couplingHigh-strength bolts and self-locking nuts are used to connect the flanges at both ends to other mechanical components. The transfer torque is transmitted through the friction between the flange end key and the flange. SWP type related connection dimensions and bolt pre-tightening torque are in accordance with the regulations in Figure XNUMX and Table XNUMX; SWC type related connection dimensions and bolt pre-tightening torque are in accordance with the regulations in Figure XNUMX and Table XNUMX. 

         The bolt can only be inserted from the flange side that matches the coupling, and the nut is made ofUniversal couplingTighten the flange side, the mechanical properties of the bolts should meet the 3098.1 level in GB10.9, and the mechanical properties of the nuts should meet the level 3098.4 requirements in GB10.
