BW-WY型外压轴向型波纹补偿器

BW-WY outer-pressure axial corrugated compensator

Page39

BW-WY型外压轴型波纹补偿器由承受外压的波纹管两端分别与外套管与内接管和法兰相连，组成只用于吸收轴向位移而不能承受波纹管压力推力的膨胀节。可设置内筒导流，方向需与流向一致，产品上的小拉杆不是承力构件，当需要作为限位时需注明。

One side of the bellows of the compensator is connected with the outer pipe and inner pipe while the other side with the flange. The compens-ator is used to absorb axial displacement but cannot bear the pull or thrust of the bellows. Inner draft-tube can also be installed as long as it is consistent with the direction of the current. The small rod is not load-bearing components and it should be noted when used as restrictor.
