Composition of D-type large deflection loose sleeve compensation joint

The main structures of D-type large deflection loose sleeve compensation joints include:

1. Stub flange: Connect the two ends of the pipe.
2. Body: Cylindrical structure with two movable short pipes with flanges passed inside.
3. Gland: For fixing and sealing.
4. Sliding pipe: Allow the pipe to expand and contract freely within a certain range.
5. Sealing device: Including sealing ring and O-type sealing strip to ensure sealing performance.

The working principle of the D-type large deflection loose sleeve compensation joint

1. Displacement compensation function: When the pipeline is displaced due to temperature changes or other factors, the loose sleeve compensation joint can move freely along the axial and radial directions of the short pipe to achieve displacement compensation.
2. Limiting device: In order to prevent the loose sleeve from compensating for excessive displacement of the joint, resulting in pipeline damage or leakage, a limiting device is set. The limiting device is generally composed of limiting blocks, limiting bolts, etc., which can be set according to the design requirements of the pipeline.
3. Sealing performance: The sealing ring is set between the loose sleeve compensation joint and the short pipe to prevent medium leakage. The sealing ring is generally made of high-temperature, corrosion-resistant, and wear-resistant materials to ensure that good sealing performance is always maintained during operation.

Product application scenarios

D-type large deflection loose sleeve compensation joint is suitable for urban heating, gas and other pipeline projects, and has the advantages of reasonable structure and reliable performance. In the process of design and installation, the displacement and displacement direction of the pipeline should be fully considered, and the type and specification of the compensation joint should be reasonably selected to ensure that it can fully play its role.
