The working performance of expansion joint improves the security reliability of expansion joint, ensures the normal operation of piping.
In order to solve the above technical problems, used technical solution is：A kind of transverse direction self-supporting bend pipe pressure balance type is swollen
Swollen section, expansion joint successively by be in series end pipe component, balance bellows A, intermediate tube, work bellows, three-way component, balance
Bellows B and closing end component composition, the media outlet of three-way component is down-set, and bearing bar is additionally provided with above expansion joint, holds
Weight bar axis it is parallel with expansion joint axis, bearing bar have on expansion joint axis direction there are three be in same straight line on simultaneously
To the supporting point that bearing bar is supported, two of which supporting point is arranged on three-way component, another supporting point is arranged on
On intermediate tube, the supporting point at intermediate tube is arranged on as constant force spring component, preset upward spring carries in constant force spring component
Lift F, lifting force F and intermediate tube and working media are equal in weight.
Constant force spring component described in the utility model includes constant force spring and suspension hook, and one end of suspension hook is through after bearing bar
It is connected with intermediate tube, the constant force spring being pre-compacted on bearing bar is arranged on the other end of suspension hook.
Bearing bar described in the utility model is hollow stem.
The utility model advantageous effect is：The structure not only can guarantee expansion joint compensation compared with ability, but also can ensure expansion joint
Working performance, reduce the security risk of expansion joint, improve the security reliability of expansion joint.

Specific embodiment
As shown in Fig. 2, a kind of transverse direction self-supporting bend pipe pressure balance type expansion joint is mainly by end pipe component 2, balance ripple
Pipe A15, work bellows 7, intermediate tube 8, three-way component 4, balance bellows B3, closing end component 1, pull rod 10, bearing bar composition.
The media outlet of three-way component 4 is down-set, and the both ends being in addition in a straight line connect balance ripple respectively
Pipe B3 and work bellows 7, the axis of bearing bar 5 is parallel with expansion joint axis, and setting after mounting expansion joint just on
Side, bearing bar 5 haves that there are three be on same straight line and the support that is supported to bearing bar 5 on expansion joint axis direction
Point, the stress of three supporting points vertically upward, by setting two supporting points in expansion joint three-way component, are added at intermediate tube
Constant force spring component mitigates the weight of intermediate tube and working media.Preset upward spring lift force F in constant force spring component 9,
Spring lift force F and intermediate tube and working media are equal in weight.The structure can be prevented effectively because of intermediate tube and working media
Weight causes swelling red sandstone to deform, and effectively reduces the security risk of expansion joint.Ensure the working performance of expansion joint, carry
The security reliability of highly expanded section ensures the normal operation of piping.
As shown in figure 5, constant force spring component 9 includes constant force spring 13 and suspension hook 11, one end of suspension hook 11 passes through bearing bar 5
It is connected afterwards with intermediate tube 8, the constant force spring 13 being pre-compacted on bearing bar 5 is arranged on the other end of suspension hook 11.It can be in
Between pipe 8 lifting lug is set, suspension hook 11 is hooked on lifting lug, can adjust height of the bearing bar 5 in the supporting point using this kind of structure, together
When also have certain depressurization.To be protected to constant force spring 13, spring box 14, bullet can be added above bearing bar 5
The suspension hook 11 for being arranged with constant force spring 13 is equipped in spring case 14.
Other two is arranged on the supporting point on three-way component 4, as shown in figure 4, the supporting point among bearing bar 5 is
Bearing bar 5, is fixed on saddle component, saddle component 7 is fixedly welded on threeway group by fixed setting by fixing bolt
