KKT type clamp type rubber flexible coupling adopts clamps instead of flanges and bolts, when using, it is convenient to set the two pipe openings of the clamp type rubber coupling on the pipeline to be connected, and connect the rubber coupling with the pipeline fixedly through the clamp, and then loosen the clamp when disassembling. It has the characteristics of simple structure, easy loading and unloading, wide range of use, oil and corrosion resistance, vibration and noise reduction, and compensation displacement. Widely used in municipal water conservancy, waterworks, chemical sewage treatment, industrial construction and other fields.
