Performance characteristics of axial external pressure bellows expansion joint: axial external pressure bellows expansion joint consists of inner cylinder, bellows, outer cylinder and accessory components.The bellows is subject to external pressure, good closure and bending resistance, and can absorb large displacement.It can be made into single, compound, two-way and other forms.Axial outward pressure bellows expansion joint mainly absorbs axial displacement, has the advantages of large compensation, good heat preservation and residual medium can be excluded.
Notes on the installation and use of axial external pressure type bellows expansion joint:
- The direction of liner cylinder should be the same as the medium flow direction (there is a flow direction sign on the expansion joint).
- When installing, note that the air vent is facing upwards and the water outlet is facing downwards.
- After installation on site, the small tie rod must be removed.
