The place of class bearing.When certain suspension centre in pipe-line system thermal walking be greater than 12mm, select constant force spring support to hang to support, preferably to keep away
Exempt from pipe-line system and generates dangerous bending stress and unfavorable stress transfer.
Existing patent 201721813324.2 discloses a kind of heating power displacement compensation device based on variable spring pull rod,
Including bellows, supporting plate, support column, pin shaft, pull rod, fixed rotating shaft, the bellows connecting with thermal pipe is placed in supporting plate plane,
Supporting plate is held by four pull rods, and respectively there are a support column in supporting plate two sides, and the top of every support column hangs two pull rods, and two
It connects respectively on pull rod a variable spring；The top of support column respectively hangs two pull rods；Pull rod is set in the junction of support column
There is pin shaft, pull rod is equipped with fixed rotating shaft in the junction of supporting plate；The supporting plate other end is slided in fixed movable upper end.Especially disc spring
Or dished spring assembly.It uses the characteristic design of the heated slightly relaxation of tab (s) spring, but bellows directly places and supporting plate on,
When bellows stretches, the bellows on supporting plate is directly contacted with supporting plate, be easy to cause the frictionally damage of bellows.
Utility model content
Purpose of utility model: in order to overcome the deficiencies in the prior art, the utility model provides a kind of heating power displacement
Compensation device can effectively prevent the abrasion of bellows, increase its service life.
Technical solution: to achieve the above object, the technical solution adopted in the utility model are as follows:
A kind of heating power displacement compensation device, including bellows, loading plate, column, shaft one, pull rod one, pull rod two, shaft
Two, spring, curved support, ball, temperature-compensating spring be can be changed, wherein described pull rod one end passes through shaft two and the carrying
Plate connection, one end of the pull rod two are connect by shaft one with column, the variable spring be connected to pull rod one, pull rod two it
Between, so that the loading plate is suspended on column；The curved support is mounted on the top of loading plate, and the temperature-compensating bullet
Spring is mounted on the lower section of loading plate, and ball is provided on the arcwall face of the curved support, and the bellows is mounted on arc branch
On the arcwall face of support.
Preferred: the arc height of the curved support is between 1/4 to the 1/2 of ripple pipe diameter.
Preferred: the ball is uniformly distributed on the arcwall face of curved support.
Preferred: the column is divided into two sides, and the loading plate is located among the column of two sides.
Preferred: the variable spring, temperature-compensating spring are butterfly-shaped spring cascaded structure.
The utility model compared with prior art, has the advantages that
Bellows is placed in curved support 8, can effectively be prevented by setting curved support 8 by the utility model
Bellows moves left and right, by being arranged ball on the arcwall face of curved support 8, when bellows expanded by heating, on ball
It is mobile, contact of the bellows between curved support is reduced, switchs to rolling friction, can effectively prevent the abrasion of bellows.
Bit shift compensation is carried out using 10 two variable spring 7, temperature-compensating spring springs, i.e., by variable spring to the wave on loading plate
Line pipe compensates, and is compensated by temperature-compensating disc spring and variable spring to the bellows in temperature-compensating disc spring, therefore
It can compensate the bellows of various states.
Detailed description of the invention
