Embodiment 1
[0033] Such as figure 2 As shown, the bellows 3 of the expansion joint is an external pressure structure, one end of the bellows 3 is fixed on the end pipe through the bellows adapter 5, one end of the bellows 3 is connected to the end ring assembly 2, and the end ring assembly 2 is connected to the outer pipe 4 and the middle The pipe assembly 9 forms the external pressure cavity of the bellows 3. During operation, the pressure of the medium enters the external pressure cavity through the gap between the guide cylinder assembly 6 with wear-resistant lining and the retaining ring assembly 7 with heat-insulating ceramic fiber. cavity. A dust-proof sealing ring 8 is arranged between the guide tube assembly 6 with wear-resistant lining and the retaining ring assembly 7 with heat-insulating ceramic fiber, which is used to prevent smoke and dust from entering the external pressure cavity. Two sets of corrugated pipes 3 and two end pipes 1 are symmetrically arranged around the mid...
Embodiment 2
[0037] Such as image 3 As shown, the structure of this type of expansion joint is a planar proportional connecting rod structure. figure 2 The universal ring assembly 11 is missing, which is used to compensate the axial displacement and the lateral displacement of a plane.
Embodiment 3
[0039] Such as Figure 4 As shown, the bellows 3 of this type of expansion joint is an external pressure structure, one end of the bellows 3 is fixed on the end pipe through the bellows adapter 5, one end of the bellows 3 is connected to the end ring assembly 2, and the end ring assembly 2 is connected to the outer pipe 4 It forms the external pressure cavity of the bellows 3 with the intermediate pipe assembly 9. When working, the pressure of the medium enters the outer chamber through the gap between the guide cylinder assembly 6 with wear-resistant lining and the retaining ring assembly 7 with heat-insulating ceramic fiber. pressure cavity. A dust-proof sealing ring 8 is arranged between the guide tube assembly 6 with wear-resistant lining and the retaining ring assembly 7 with heat-insulating ceramic fiber, which is used to prevent smoke and dust from entering the external pressure cavity. The two groups of corrugated pipes 3 and the end pipes 1 are arranged symmetrically...
