The

double flange power transmission expansion joint is composed of upper and lower flanges, a middle wing ring, a short pipe, a power transmission screw and other components. Under what circumstances does the pipeline use the power transmission joint ? When laying pipelines, especially steel pipe lines, the positions of all equipment and valves on the pipelines are marked on the construction drawings. The force transmission joint is used at the front end of the valve to compensate for the lateral displacement of the pipeline and generally transmits force. The installation position of the joint should be in a straight line. If it is installed at a corner, try to use bellows or rubber joint instead. There are two materials for making force transmission joints, one is Q235, and the other is ductile iron.

There are many bolts on the power transmission joint. Basically, every space of the flanges on both sides has bolts penetrating through it, occupying half of the product. During work, the adjusting bolts are mainly used to ensure the operation of the pipeline. The force transmission connector is made by adding a flange coupling and a force transmission screw on the basis of the flange loose sleeve compensation connector. Different from loose sleeve compensation connectors and loose sleeve limit compensation connectors, the compensation amount of sub-category compensation connectors refers to the control amount during installation and disassembly. Once all the screws are tightened, is rigidly connected to , which can transmit axial force to maintain gate valve , pump and other mechanical equipment.

The force-transmitting expansion joint is exposed to acid and alkali corrosion, mechanical wear and the aging of the telescopic shortening itself during use, resulting in the service life of the telescopic shortening of the force-transmitting expansion joint. Generally, the service life of the expansion joints used in the ceramic and coal industries is about 3 to 5 months. The service life of the expansion joints used in sewage treatment will be relatively longer. Once the telescopic shortening is damaged, it should be replaced in time to avoid affecting the treatment effect and subsequent processes.
