Purpose and scope of application:
this standard applies to the displacement range for VS (
0~180mm)
TD (
0 ~ 120毫米)
, load range is 154 ~ 217384 n, using temperature range -
Steam-water variable
spring of 20 ℃ ~ 200 ℃.
boiler steaming-water pipe or in steam-water spring is mainly used for power equipment, the thermal displacement and its equipment in the operation of the device.
Calculated and determined according to the pipeline stress situation of the work and the thermal displacement steam-water spring requirements, our factory will be carried out in accordance with the design load setting steam-water spring: spring preloading and set by the cold load position;
At the same time, the theoretical working position to be in the cold.
control valve set of steam-water pipes of the spring position: control valve group supports under the pipe elbow, usually for the normal temperature of the pipeline can be fixed frame, with thermal pipeline, should according to the requirements of the flexible analysis will be set to a fixed frame, a frame another set to slide or guide frame.
If valve group is very long, only on both ends of the valve group support, can make the valve group of intermediate prolapse is larger, should add a bracket in the middle, the middle bracket to use adjustable bracket, in order to install.
Can also be set to a fixed frame, middle frame expansion to the displacement on both ends.
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 line displacement and absorption of vibration, 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.
