The flexible rubber joint sphere is pulled out from the grooved flange. Anti-pull device, also known as limit anti-pull device, is to add a limit device to the original product performance. When flexible rubber joints are used for high-rise water supply, the pipeline shall have fixed support or fixed bracket, otherwise the product shall be installed with anti-pulling device. The force of fixed support or bracket shall be greater than the axial force, otherwise the product shall also be installed with anti-pulling device.
Flexible rubber joint is a kind of flexible connector specially used for metal pipeline. It is widely used in various industries or high-rise building water supply and drainage systems, heating and ventilation systems, air-conditioning and fire-fighting systems, absorbing temperature changes, pipeline assembly errors and uneven ground settlement, pipeline displacement compensation, balancing deviation, isolating mechanical vibration and reducing noise, which can effectively prevent or reduce damage and loss of equipment, pipelines and buildings. Elastic support in addition to metal springs, air springs, etc., common rubber fabric metal composite flexible rubber joints.
