The curved tube pressure balance compensator is mainly used to absorb axial and lateral combined displacement and to balance the pressure thrust of the bellows. The expansion joint is a bellows structure, which is composed of pressure balancing bellows and compensating bellows. The pressure of bellows compensator is balanced by pressure balancing bellows, and the self-thrust of compensator and pipeline is relieved.
Product features
The expansion joint has a working bellows at both ends, and a Balanced Bellows in the middle. The expansion joint bears the internal pressure thrust through the force components (large pull rod or tongue tube), so the pipe system only needs the intermediate fixed bracket. Such expansion joints can only absorb axial displacement.
purpose
It fundamentally solves the problem that the blind plate force pushes the fixed support, thus simplifying the design and construction of the fixed support and reducing the project cost. Pressure-balanced expansion energy-saving compensation pipeline system axial displacement, internal pressure thrust self-balance, this product is used in high-object position pipeline which is not suitable for fixed support.
Matters needing attention in installation and use
1. Such expansion joints are generally installed on overhead straight lines and installed horizontally.
2. After the expansion joint is installed, all the small pull rods must be removed.
3. In order to reduce the elastic reaction of the expansion joint to the support, the expansion joint can be pre-tensioned or pre-compressed before installation (by adjusting the small tie rod on it).
