Constant force spring customized on-demand customized supply steam-water spring

Relief valve position determination of steam-water pipes of the spring: relief valve nozzle under external load caused by the bending moment requires small as far as possible, so as not to affect the performance of the valve body deformation. In addition to consider when setting stent pipeline under the gravity load, also should pay attention to when the discharge fluid reaction force and its direction. Safety valve outlet pipe bracket of a root point should not take root in the flexible large steel structure, at the same time supporting points of vertical thermal displacement should be small as far as possible. On the higher temperature of pipe, valve export levels should be long enough, avoid stents escapes. Relief valve suddenly open, prone to vibration, especially large diameter, large differential pressure relief valve should be paid attention to vibration control, the outlet pipe of gas-liquid two phase, more attention should be paid to vibration control and avoid water hammer.

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;

spring hanger according to the principle of moment balance 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. 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.
