Variable is mainly composed of cylindrical helical
spring, steam-water 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.

the 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 ℃.
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.
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.
