Description
Technical field
The utility model relates to a kind of vacuum pipe, especially a kind of Hermetical connecting structure of vacuum pipe.
Background technique
Existing vacuum pipe is single-layer pipeline mostly, i.e., shell is solid, and after the connection of more piece pipeline, inner cavity is
It communicates, in this way, can not just determine is which length of tubing is leaked, needs to check in turn, greatly improve maintenance difficulties, take
When it is laborious.Even if existing vacuum pipe is equipped with end plate, also only plays the role of reinforcing and connection, not can solve above-mentioned
Technical problem.
Utility model content
A kind of sealed connection of vacuum pipe is provided the purpose of the utility model is to overcome the above-mentioned insufficient of the prior art
Structure, can either improve the end intensity of pipeline, and can quickly judge leak position, convenient for safeguarding.
The technical solution of the utility model is: a kind of Hermetical connecting structure of vacuum pipe, and the shell of vacuum pipe is folder
The both ends of layer structure, every length of tubing are equipped with end plate, and the interlayer end of the shell is sealed by end plate.
Above scheme has the advantage that the both ends setting end plate of (1) every length of tubing, on the one hand can reinforce pipe end
Intensity, on the other hand, convenient for connection；(2) vacuum pipe of sandwich is combined with end plate, due to interlayer and vacuum pipe
Inner cavity be not communicated with, sealed by end plate, can quickly judge it is the leakage of which length of tubing, because of the interior outside of interlayer
It is pipeline shell, no matter interior side body or outside shell leak, can quickly judges which section leaks, just
In later maintenance, convenience is greatly improved.
Further, multiple gussets are equipped between the end plate and the tube wall of vacuum pipe.In such manner, it is possible to further by pipeline
End reinforce.
Further, the end plate of two adjacent sections pipeline is connected by expansion joint.
The expansion joint of the utility model refers to retractable structure, and the shape of expansion joint is not construed as limiting, such as bellows, or
Guan Shangshe groove etc., as long as being able to achieve flexible.Vacuum pipe is formed by connecting by multistage pipeline, and the length of every segment pipe is identical
Or it is different, expansion joint is set between adjacent two pipeline.It is swollen since vacuum pipe is easily expanded with heat and contract with cold by the variation of environment temperature
Swollen section changes and corresponding change with pipeline, so that it is guaranteed that pipeline is completely embedded.In addition, expansion joint be can arbitrarily curved structure,
When multiple single hop pipelines need to turn, bending angle can pass through expansion joint flexible modulation.
Further, the end plate of every length of tubing at least one end is equipped with the stomata being connected to interlayer.Stomata is set, convenient for folder
Layer vacuumizes, so that interlayer is in vacuum state.The advantage of this structure is: (1) interlayer make single layer gas leakage do not influence vacuum
Performance, such as interior side body gas leakage would not influence the vacuum performance of vacuum pipe, and then will not as long as outside shell is air tight
The normal operation for influencing vacuum pipe interior vehicle can complete maintenance and leak repairing in the case where not stopping transport；(2) pass through setting folder
Layer, since the pressure of interlayer is between the pressure outside vacuum pipe inner cavity and vacuum pipe, such as detects the pressure of interlayer
Become larger, shows that layer of big gas leakage of pressure；If the pressure of interlayer becomes smaller, show that layer of small gas leakage of pressure.In this way, can be quickly
Judge be which length of tubing which layer shell gas leakage, greatly improve convenience, high reliablity for the maintenance in later period.
Further, the shell includes first panel, second panel and set on interlayer between the two, the folder of every length of tubing
Pressure sensor is equipped in layer.First panel and second panel are equivalent to the outside shell and inner shell of pipeline.Interlayer is
Between two panels and the structures of two panels is supported, such as interlayer is multiple hollow pipes between two panels, it can also be with
It is corrugated core, wave core etc..Wherein, the cross sectional shape of hollow pipe can be round, ellipse or the side N shape, and N >=3 are also possible to
Other special pipes.Contact surface is equipped between interlayer and at least panel, if hollow pipe is equipped with flange, to increase between panel
Bonding strength.It can be attached by soldering or electric resistance welding etc. between interlayer and upper and lower panel.Gap, phase are equipped in interlayer
For the existing honeycomb core being connected, convenient for vacuumizing.
Pressure sensor can be pressure gauge, be also possible to the knot of the sensor connecting with microprocessor or the two
It closes.At least one settable pressure sensor in the interlayer of every length of tubing.And the inner cavity of pipeline can be every section and be respectively provided with pressure
Force snesor is also possible to interval setting.
Further, the both ends of every length of tubing are equipped with support base.Support base plays the role of supporting pipeline.
Further, the support base of every length of tubing at least one end is movable pedestal, the lower part of movable pedestal and support vacuum tube
It is flexibly connected between the supporter in road.Movable supporting seat can be moved with expanding with heat and contract with cold for vacuum pipe.
Wherein, if vacuum pipe high-altitude is set up, supporter can be pillar, bridge pier etc.；If vacuum pipe is set up along ground,
Supporter can be the other support constructions being connected between vacuum pipe and ground.
Preferably, the support base of every length of tubing one end is movable pedestal, and other end support base is fixed base frame, movable pedestal
Lower part and support vacuum pipe supporter between be flexibly connected, be fixedly connected between the lower part and supporter of fixed base frame.
Further, the support base is directly connect with the tube wall of vacuum pipe；Or support base passes through connecting plate and vacuum
The tube wall of pipeline connects.Wherein, it is connected by connecting plate, stress surface can be increased, in particular for the tube wall of thinner thickness, led to
It crosses connecting plate and increases stress surface, also reduce support base to the pressure of tube wall.
Further, described to be flexibly connected to be slidably connected or rolling connection.The mode of flexible connection can be idler wheel, ball
Connection etc., sliding type can be sliding block, sliding spiral shell etc..
The utility model has the beneficial effects that (1) can reinforce the intensity of pipe end by setting end plate, it is especially thick
Relatively thin tube wall is spent, is capable of increasing stress surface, and be convenient for connecting with other length of tubing by end plate；(2) by the pipe of sandwich
Road is combined with end plate, can quickly be judged it is which length of tubing leakage, is convenient for later maintenance, greatly improve convenience.
