Constant force spring spot supply tension spring

Steam-water pipe spring pipe bracket structure form of design and selection is an important part in the design of pipe system, pipe bracket in addition to support the piping weight, constant force spring hanger, special pipe bracket can balance the piping forces, limit pipe vibration displacement and absorption, steam-water VS spring, in the pipe system design, reasonable structure of the pipe bracket, correct selection and arrangement, can improve the stress distribution of the pipeline and the force of pipe rack, ensure the safe operation of the pipe system, and extend its service life.

steam-water spring working principle and design principle: according to the moment balance the original design. Within the prescribed scope of load displacement, load torque and spring torque is always in balance. Therefore, supported by constant crane pipeline and equipment displacement occurs, can get constant supporting force, will not bring additional stress to piping and equipment. Constant condole commonly used in need to reduce the stress, displacement, such as power station boiler of power plant steam, water, smoke air ducts and burner, such as suspension parts, and petrochemical equipment, and other places need to reduce the displacement stress. To install and use:


1, type A: derrick on one end is connected with the root; At the other end with steam-water thread screw in the spring of roof bolt hole, and lock nut. Basket nut bottom connected to the pipe top derrick with screw thread, rotating basket nut, the installation position of pipe segments to rules, and then use nut locking;
2, B, C: top with derrick or steam-water spring hanger, derrick, hanging plate on the other end to take root in the girder or floor. Other same as type A;
3, type D: bolts will be fixed on the girder or floor, steam-water spring boom across the hanger ontology and pipes, rotating the top nut, to pipeline hoisting installation location, and then use the nut lock;
4, E: bolts on the steel beam or slab with steam-water will spring. Other same as type A;
5, F type: bolts will spring steam-water plate fixed on the foundation, the steel beam or slab, the top level of support at the bottom of the pipe or the bend. When the actual supporting height and provide installation height from design, rotating load column fine-tuning. Its between Lmax and Lmin amount of fine-tuning. Spring model VS30F0 ~ 9 + 6 mm, VS30F10 ~ 24 for + 12. 5 mm, spring model VS60F, VS90F, VS120F, VS150F, VS180F + 25 mm respectively;
6, type G: rotating basket nut, make on the steel beam or slab with derrick taut, adjust the hanger to design the installation height, then the basket with nut nut lock.

steam-water variable spring is mainly composed of cylindrical helical spring, displacement dashboards, shell and parts such as elastic nut.
steam-water variable spring according to the different methods of installation, can be divided into A, B, C, D, E, F, G seven type.
type A - - - - On the thread type suspension;
B - - - - Single ear suspension type;
- C type - - - - - - - - Ears hanging type;
- D type - - - - - - - - On the adjusting suspended type;
E - - - - Under the adjusting suspended type;
F - - - - Support on type;
- G type - - - Parallel suspension type;
