Description
Technical Field
The utility model relates to a spring hanger with a horizontal displacement compensation device, and belongs to the technical field of hangers.
Background
The spring support and hanger is suitable for various pipelines and equipment which generate thermal displacement in operation, has the functions of bearing load, limiting displacement, controlling vibration and the like, and has the characteristics of stable support and hanger, convenient installation, reliable operation and the like. The hanging bracket is widely applicable to hanging and supporting parts of hot water and flue gas coal pipelines of power station boilers and power plants and other places needing hanging, such as petroleum and chemical devices.
With the rapid development of petrochemical industry and electric power industry in China, a hanger at a large thermal displacement position of a high-temperature pipeline due to thermal expansion deflects a hanger pull rod in the installation process, so that additional force is generated on the pipeline at one end of the hanger, additional force is generated on a steel structure at the other end of the hanger, and if no measures are taken, the additional force of a pipeline system is finally transmitted to an equipment interface through pipe fittings such as an elbow, a tee joint and the like, so that the strength of the pipe fittings and the safety of equipment are influenced. Previously, to avoid excessive additional forces, design regulations required hanger brace deflection angles of no more than three to four degrees. In order to meet the requirement, for a support hanger with large thermal displacement and large pull rod deflection angle, the deflection angle can be reduced by lengthening the pull rod of the hanger, and the hanger can also be installed in a deflection manner to reduce the deflection angle, but other problems can be caused by changing the length or the installation angle of the hanger, and the problems cannot be fundamentally and effectively relieved or solved.
