Embodiment
With reference to the accompanying drawings the specific embodiments of the utility model is carried out detailed explanation.
Fig. 1 is that the pipeline flexible connecting device first of the utility model is implemented structural representation; The pipeline flexible connecting device is made up of at least one group of pipeline flexible connecting device unit; Every group of device unit is made up of metal bellows that is no less than two-layer mutual cover and two end connections; Form at least one enclosed space mutually between the metal bellows of cover, metal bellows comprises the straight section metal tube of bellows structure and end certain-length; In the metal bellows of described two-layer at least mutual cover, the disposed outside of one deck metal bellows has enhancement layer at least.
As shown in Figure 1; The single assembly unit of pipeline flexible connecting device specifically comprises first metal bellows 1, be close to be arranged in the first outside enhancement layer 2 of first metal bellows 1, cover is arranged in the second outside metal bellows 3 of first metal bellows, is close to and is arranged in the second outside enhancement layer 4 of second metal bellows mutually with one heart, is provided with link in the end of first metal bellows 1 and second metal bellows 3.First metal bellows 1 and second metal bellows 3 comprise the first straight section metal tube 5 or the second straight section metal tube 6 of bellows structure and end certain-length respectively; And the external diameter of the first straight section metal tube 5 is less than the internal diameter of the second straight section metal tube 6; The link 8 of first metal bellows 1 and second metal bellows, 3 ends can or be welded to connect part for flange connector or threaded connector.Be specially the bending link of straight section link or vertical bending link or several angle.
In order to obtain excellent mechanical intensity more; For example tension compressive strength and Safety performance; First enhancement layer 2 is close to and is arranged in first metal bellows, 1 outside, and is fixed in the outer wall of the first straight section metal tube 5 through particular form, for example the mode through welding means of fixation or other pressing.Same mode, second enhancement layer 4 are close to and are arranged in second metal bellows, 3 outsides, are fixed in the outer wall of the second straight section metal tube 6 through particular form, for example through the welding means of fixation; To strengthen the mechanical strength of outer metal bellows, tension compressive strength for example.Preferably, for example first enhancement layer 2 and second enhancement layer 4 form for synthetic fibres or the braiding of wire rule enhancement layer.
In order to obtain good heat insulation effect; At least one enclosed space that forms between the metal bellows of cover mutually is in vacuum state; For example separation has the supporting structure that supports the two between first metal bellows 1 and second metal bellows 3; And the formed enclosed space in the space of the two formation is in vacuum state; The space keeps vacuum state, also can space between first metal bellows 1 and second metal bellows 3 kept obtaining through sealed after being vacuumized or through continuously or be interrupted to vacuumize and obtain vacuum state, to reduce the convection current release of first metal bellows 1 to second metal bellows, 3 heats; And the disposed outside at second enhancement layer 4 or second metal bellows 3 has the low thermal insulating material of heat conductivity, reduces the heat that the pipeline flexible connecting device discharges to the external world.
On the enhancement layer wall of the bellows outer wall of non-innermost layer or this layer bellows, be furnished with at least one temperature transducer; Leakage problem with the signal piping flexible connecting device; For example arrange at least one temperature transducer 7 on second metal bellows 3 of the pipeline flexible connecting device shown in Fig. 1 or second enhancement layer 4; In normal course of operation, because the space between the double layer of metal bellows is a vacuum state, excellent heat insulating performance; First metal bellows, 1 inner flow working medium heat outwards transmits less, and the temperature on second metal bellows 3 or the second enhancement layer pipe, 4 walls is relatively low.And taking place under the situation of leaking: for example; When first metal bellows 1 takes place to leak; High temperature fluid working medium can flow in the space between first metal bellows 1 and second metal bellows 3; Directly contact, cause temperature transducer 7 measured values on this pipe outer wall or its enhancement layer wall to rise rapidly with second metal bellows, 3 inwalls; Moreover; When second metal bellows 3 takes place to leak; And first metal bellows 1 is not when taking place to leak, and outside air can enter in first metal bellows 1, second metal bellows 3 enclosed space between the two through second metal bellows 3, forms convection current heat conduction; More heat is delivered to second metal bellows, 3 inwalls from first metal bellows, 1 outer wall, makes that also the temperature sensor measurement value rises on the wall; Both of these case can be through making judgement to the change curve analysis of measured temperature parameter, for further site inspection processing provides foundation; Even and both of these case descends when taking place separately (the simultaneous possibility of these both situation is extremely low); Also there are one of them second metal bellows 3 or first metal bellows 1 not to leak; Can play seal action; Can not cause the extensive leakage accident of internal flow, strengthen operational safety performance; Therefore as long as detect, in time handle above-mentioned leakage situation is on-the-spot, the double layer of metal bellows structure can improve system's safety in operation greatly.The position of temperature transducer 7 should help in time finding above-mentioned two kinds of leak cases, for example be arranged near the gravitational direction minimum point.
What be worth explanation is, the single assembly unit of this pipeline flexible connecting device can comprise the multilayer metal bellows of cover mutually, and the outer wall of single metal bellows can be arranged one deck enhancement layer at least; Multilayer is overlapped in formed at least one enclosed space of metal bellows mutually, and at least one enclosed space implements to vacuumize processing; This pipeline flexible connecting device can be applicable to the flexibly connecting of heat collector pipeline of solar energy heat utilization field.
