Detailed description of the invention
As in figure 2 it is shown, be the composite plane hinge straight pipe pressure-balancing type expansion joint of a kind of staged arm-tie, mainly include
Two groups of work corrugated tubes 4, balance corrugated tube 8, end pipe A at two ends and end pipe B, intervalve assembly A7-1 or intervalve assembly B7-2
One end connects balance corrugated tube 8, the other end of intervalve assembly 7A7-1 or intervalve assembly B7-2 and work corrugated tube 4
One end connects, and the other end of work corrugated tube 4 connects end pipe A 1 or end pipe B 10, in the outside of two groups of work corrugated tubes 4 respectively
Being provided with plane hinge device, plane hinge device respectively arranges two groups, along the peripheral 180 ° of layouts of expansion joint.Plane hinge device by
Short secondary hinge plate A 3-1, connecting plate A11, long main hinge plate 9-2, short secondary hinge plate B 3-2, connecting plate B14, long secondary flap
9-1 is constituted, and short secondary hinge plate A 3-1 is horizontally disposed with, and its one end is fixed on end pipe B10, under its other end and connecting plate A11
Holding hinged, the upper end of connecting plate A11 is fixing with long main hinge plate 9-2 one end to be connected, and the long main hinge plate 9-2 other end is fixedly installed
On intervalve assembly B 7-2, short secondary hinge plate B 3-2 is horizontally disposed with, and its one end is fixed on end pipe B 10, its other end with
