D type large deflection loose sleeve compensation joint

D-type large deflection loose sleeve compensation joint, including a cylindrical body, the interior of the body passes through two movable short pipes with flanges; the connecting ends on both sides of the body are respectively connected with a gland with bolts and tightened with nuts. A ring of sealing strips is arranged on the connecting surface of the body and the gland; a retaining ring is installed on the inner side of both ends of the body, the retaining ring is sleeved on the outer side of the short pipe, and a limit block is installed on the short pipe; A sealing ring is installed between the ring and the gland. The sealing ring is U-shaped and embedded in a rectangular groove inside the gland. The sealing ring is in contact with the outer wall of the short tube, and the contact surface between the sealing ring and the outer wall of the short tube is a cylinder An O-shaped sealing strip is installed inside the sealing ring, and a protruding lip is provided on the upper inner surface of the sealing ring. The lip can prevent the sealing strip from falling off from the sealing ring, and the sealing strip can ensure that the sealing ring is short The outer wall of the tube generates a continuous pre-tightening force, thereby ensuring the sealing between the body and the inner cavity of the short tube.

Data Sheet

Features of D type large deflection loose sleeve compensation joint:

It adopts unique anti-axial force design, simple structure, reliable sealing performance and strong pull-off resistance. It has a large amount of flexibility and expansion, and is used for absorbing axial displacement and angular displacement of 6° to 7°. It is suitable for pipelines in harsh working conditions and complex terrain. The D-type large deflection loose sleeve compensation joint can expand and contract axially within a certain range, and can also overcome the offset caused by the connection of pipes in different axial directions within a certain angle, which can greatly facilitate the installation and disassembly of valve pipes. It has the following functions: compensating and absorbing the axial, lateral and angular thermal deformation of the pipeline; absorbing equipment vibration and reducing the impact of equipment vibration on the pipeline; absorbing the deformation of the pipeline caused by earthquake and subsidence. It plays a good role in regulating the expansion and contraction of long-distance pipelines due to temperature difference.

Advantages of Huashunying D-type large deflection loose sleeve compensation joint:
