The safe operation of expansion joint directly affects the security of pipeline.Therefore need to design a kind of higher expansion joint production of security performance
Product, the product can not only meet the compensation thermal walking ability of expansion joint, and have self-supporting function, improve expansion joint product
Security, expansion joint simple in construction.
Fig. 1 is conventional bend pipe pressure balance type expansion joint schematic diagram, and the pattern expansion joint is in use due to expansion
Section with medium reason, makes bellows deform in itself, increases the displacement load of bellows, directly affects bellows workability
Energy, have a strong impact on the normal operation of piping.
The content of the invention
In order to solve the above technical problems, the present invention provides a kind of horizontal self-supporting bend pipe pressure balance type expansion joint, pass through
Constant force spring component is set up at expansion joint intervalve, mitigates the weight of intervalve and working media, effectively can prevent because in
Between pipe and working media weight, cause swelling red sandstone to deform, effectively reduce expansion joint security risk.Ensure expansion
The service behaviour of section, the security reliability of expansion joint is improved, ensure the normal operation of piping.
In order to solve the above technical problems, used technical scheme is：A kind of horizontal self-supporting bend pipe pressure balance type is swollen
Swollen section, expansion joint successively by be in series end pipe component, balance bellows A, intervalve, 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
The axis of weight bar is parallel with expansion joint axis, and bearing bar has three on expansion joint axis direction and is on same straight line simultaneously
The strong point being supported to bearing bar, the two of which strong point are arranged on three-way component, and another strong point is arranged on
On intervalve, it is constant force spring component to be arranged on the strong point at intervalve, and preset upward spring carries in constant force spring component
Lift F, lifting force F and intervalve and working media are equal in weight.
Constant force spring component of the present invention includes constant force spring and suspension hook, and one end of suspension hook is passed through after bearing bar with
Between pipe connect, be arranged with the constant force spring being pre-compacted on bearing bar on the other end of suspension hook.
Bearing bar of the present invention is hollow stem.
Present invention has the advantages that：The structure both can guarantee that expansion joint compensated the work that compared with ability, can ensure expansion joint again
Make performance, reduce the security risk of expansion joint, improve the security reliability of expansion joint.

Embodiment
As shown in Fig. 2 a kind of horizontal self-supporting bend pipe pressure balance type expansion joint is mainly by end pipe component 2, balance ripple
Pipe A15, work bellows 7, intervalve 8, three-way component 4, balance bellows B3, closing end component 1, pull bar 10, bearing bar composition.
The media outlet of three-way component 4 is down-set, and the both ends being in a straight line in addition 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, the support that bearing bar 5 has three on same straight line on expansion joint axis direction and is supported to bearing bar 5
Point, the stress of three strong points vertically upward, by setting two strong points in expansion joint three-way component, are set up at intervalve
Constant force spring component, mitigate the weight of intervalve and working media.Preset upward spring lift force F in constant force spring component 9,
Spring lift force F and intervalve and working media are equal in weight.The structure can be prevented effectively because of intervalve and working media
Weight causes swelling red sandstone to deform, and effectively reduces the security risk of expansion joint.Ensure the service behaviour of expansion joint, carry
The security reliability of highly expanded section, ensure 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 intervalve 8, the constant force spring 13 being pre-compacted on bearing bar 5 is arranged with the other end of suspension hook 11.Can be in
Between pipe 8 hanger is set, suspension hook 11 is hooked on hanger, can adjust height of the bearing bar 5 in the strong point using this kind of structure, together
When also there is 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 provided with spring case 14.
