Description
Background of invention
The present invention relates to connect the joiner of pipe or conduit continuous length end, relate in particular to the joiner that connects continuous tube end in the vehicle exhaust system.
Known in vehicle exhaust system, especially in the vent systems of those heavy vehicles such as truck or earth-moving equipment car, internal combustion (i.c) motor can make outlet pipe produce significant vibration.Move motor constantly in the time of an elongated segment, can produce so-called resonance, this may cause the obvious deflection deformation of outlet pipe extended length.As time goes on, the meeting of deflection repeatedly of outlet pipe weakens pipe intensity, and it was lost efficacy.In addition, can pass through outlet pipe, this resonance is sent on the fixed block of pipe, cause the loosening of fixed block, thereby may cause the unexpected skew of one or more elements in the vent systems, this may make the people come to harm, or equipment is damaged.
Except by the vibration that vehicle motor produced, various pulling force, pressure and bending force that a vent systems is being produced when also bearing vehicle operating.Though discrete component can be done firmer greatlyyer, to overcome the inefficacy that causes because of tired, consider the reason of weight, this structure is worthless.Make discrete component more solid in addition, only vibration can be sent on the fixed block or other elements of vent systems, and can not reduce or eliminate vibration.Therefore wish to make vent systems, or the element of vent systems and this vibration and power are isolated
Known, if with the pipe of vent systems separately, rather than when extending its length continuously, can eliminate or reduce because the resonance that motor produces by non-rigid connection.This non-rigid connection can also advantageously be used for absorbing other pulling force, pressure and bending force except the vibration that can eliminate motor.
Thus, be expected to obtain a kind of joiner, be used for connecting outlet pipe, their length is continued, this joiner is to be joined in a non-rigid manner pipe, and can absorb pulling force, pressure and bending force, vibration and power can't be delivered to another root pipe from a pipe.
In the U.S. Pat 4,792,161 of Usui, can find the example of prior art joiner.In Usui, adopt the spring ring of a pair of arranged concentric, be used for providing a mechanical connection with connected pipe way.A shortcoming of the joiner among the Usui is when spring ring is in stretching or warp architecture, may between the single circle of spring ring, produce the gap, dirt, chip and moisture may be invaded wherein, owing to reasons such as wearing and tearing, get rusty, may influence the operation of spring ring like this.Therefore in addition, spring ring (their structure is and is through in) is not protected, and is subjected to the effect of element all the time, is easy to be worn or the infringement of other harmful physical contacts.Another shortcoming of the connector apparatus of Usui is: it relies on the seal ring that is arranged between overlapping end of conduit, as encapsulating method, to prevent the effusion of exhaust.Seal ring is subjected to the effect of periodic bending force, pulling force and pressure, finally jeopardizes sealability and requires to change joiner.
In the U.S. Pat 5,145,215 of Udell, disclosed another prior art connector apparatus.In Udell, inner sleeve parts are arranged in the outer sleeve parts with one heart.With one basically the unsealed shock absorption packing ring of porous be arranged between the overlapping part of collar tube sub-assembly, to eliminate the direct contact between collar tube sub-assembly.Washer part is a non-tight, to eliminate wearing and tearing, simultaneously minimum is reduced in the influence of interaction between collar tube sub-assembly and joint.The extensile bellows components of one flexibility in sleeve pipe non-overlapped end far away, mechanically is connected with collar tube sub-assembly.One isolating part is typically a knit wire, round bellows components, is used for protecting extensile bellows components not to be subjected to the infringement of external element and power.
Though the device in the Udell patent can be regulated pulling force, pressure and be connected being pivoted relative to each other of pipe end, the Udell device only has single " pivotal point ", and therefore the amount of being pivoted relative to each other that can regulate is limited to.In addition, in the compressible scope of washer part, the axle of two continuous pipes can not move to a non-relation that intersects (being oblique).In addition, the device of Udell for regulating pressure, more is applicable to the adjusting pulling force.The situation of joiner generation excess compression, though not too common also possible, so just the possibility luminous element blocks or is out of shape, and will exert an adverse impact to the later ride quality of joiner, even may cause joiner to destroy too early and inefficacy.It fails to provide suitable " a stopping " structure to prevent that this class is stuck.
Hope can provide a kind of connector apparatus of flexibility, and it has one and strengthens, and firmer structure completely cuts off a vent systems and a vibration source (as explosive motor) so that be used for.
It would also be desirable to provide a flexible coupler apparatus that is used for vent systems, it can regulate the orientation of tube end, so that realize the non-annexation that intersects (oblique).
It would also be desirable to provide a flexible coupler apparatus, its structure can provide correct stopping to move, to overcome the excess compression of connector apparatus.
According to this specification, claims and accompanying drawing, these purposes of the present invention and other purposes will become clearer.

More preferably make ring washer parts 25 and 26, have elasticity although this material is a bit loose, and can thickly clog than heavily fortified point by metallic mesh material.Also can make washer part with other materials such as resilient solar heat protection ceramic fibre materials.In preferred embodiment of the present invention, though each washer part 25,26 all is subjected to radial compression at inner piece 20 and 14,15 of pipe joint members, but the axial motion that each washer part 25,26 can both freely be done to a certain degree along inner piece 20, and may be subjected to stopping of pipe joint member 14,15 upper flanges 17,18.Made washer part the 25, the 26th, being made into can be incompressible, like this when pipe 11 and 12 is basically on same straight line, and between the pipe because of Side movement takes place or takes place when crooked because of the external force effect rotates to an angle mutually, they can absorb and overcome lateral vibration and axial vibration in the tolerance range of parts and washer part maximum compression coefficient scope.Though washer part 25,26 needs not to be loose, isolate in order to finish the ideal vibration that is connected pipe way, they must have elasticity to a certain degree at least.In addition, if desired, can with washer part 25,26 respectively field welding to pipe joint member 14 and 15 or inner piece 20 on, but be not to be soldered to simultaneously on these two parts.
Device 10 can also be provided with the stop component 28 of an annular, and it can be fixed with the outer surface of inner piece 20, and more preferably is positioned at the neutral position of inner piece length.In addition, also can around inner piece stop component 28 be set simply.More preferably, stop component 28 is by with the material identical materials made (steel wire grid, ceramic fiber etc.) of making washer part 25,26 or can be made by a harder or softer material, even can be a ring of making by pottery, metal or elastic material or other suitable durable heat insulation material, it can be assemblied on the inner piece simply, or be fixed on the inner piece 20 by welding, brazing filler metal or other suitable fixation methods.When stop component 28 not being set on setter 10, for specific application, should suitably design the size of this structure remaining part, so that in the expection operating range of this application-specific, device 10 can not be compressed to and make flange 17 and 18 adjacency.This suitable size design will prevent " trembling " that joiner in service produces.
In another structure, can replace stop component 28 with annular spring parts (a for example cup spring).
(as described, when the diameter of pipe joint member 14 and 15 during greater than end 11 and 12) can be by any known technology, as welding or brazing filler metal, will be fixedly welded on the pipe joint member 14,15 round the bellows 30 that adaptor tube parts 14,15 have end 31 and 32.In addition, if pipe joint member is to insert to be installed on end 11 and 12, and mechanical caging therein, if perhaps corrugated tube end 31,32 extends axially and exceeded pipe joint member at 14,15 o'clock, corrugated tube end 31 and 32 directly can be fixed and welded on end 11 and 12.The fold part of bellows 30 will have enough axial lengths, and the part that all like this inner pieces 20, washer part 25,26 and pipe joint member 14,15 cover inner piece 20 all has been included in the fold length partly.
The all neck rings 34,35 of pipe also can be set, make their end 31,32 assemblings round bellows.For the parts that each is different are weldingly fixed on together, can be according to known technique, adopt suitable welding, brazing filler metal and/or crimping.
Constituting can be with reference to known technology with the method for assembling above-mentioned different parts, and those of ordinary skill in the art understands formation and the installation that just can easily finish parts after the disclosure patent.Therefore the detailed description of flexible coupler 10 formations and assembling is not necessary to complete understanding structure of the present invention and operating mode.
Be in operation, flexible coupler 10 is mounted to structure shown in Figure 1 is device 10 normal state of rest basically.Though packing ring 25,26 may be by radial compression, they are not by axial compression.Owing to draw back end 11 and 12, so with controlling device 10 axial stretching, extension to a certain degree, this will cause that packing ring 25,26 is subjected to axial compression.The axial compression of device 10 will cause in the flange 17,18 or all move towards selectable stop component 28 (if it is set), and finally nestle up stop component.In addition, the washer part 25,26 that can resist all directions compressions will be under each component tolerance condition, and the deflection (see figure 2) of several angle takes place with respect to pipe (1) 2 permission pipe (1) 1.For example, be 2 inches connection set for a nominal diameter, the total angle deflection of expection is 10-12 °.
In addition, the diameter that depends on device 10, end 11 and 12, the axial length that pipe joint 14 and 15, inner piece 20 and washer part 25,26 are relevant, and other factors, can allow end 11 and 12 to take a kind of like this structure, make and still are parallel to each other end 11 and the axle of opening in 12 minutes and non-intersect or inclination (as Fig. 3) fully.The internal freedom end that promptly has the pipe joint 14,15 of flange 17,18 cooperates with the flange 22,23 and the packing ring 25,26 of inner piece 20 respectively, and so that two pivot tie points to be provided, they have rotating center at point 40 and 41 places basically.From the above mentioned, whole coupling arrangement can be regarded as the device that allows a 10-12 ° angle tilt, each pivot tie point is seen as b angle tilt or the c angle tilt that allows a 5-6 ° (be contingent whole inclination 10-12 ° half) to tilt.
According to aforementioned each angle tilt pattern, bellows components 30 should be made all combinations that can be suitable for regulating these motions, simultaneously, keep water-stop in each end, to guarantee not having gas to pass through device 10 dissipations.In addition, in installation process, if necessary, bellows components 30 allows connector apparatus 10 to be compressed or stretches, and be in operation, also allow joiner 10 to be subjected to this compression and stretching, extension, but still keep the mechanical seal of 11,12 of two tubes ends to connect simultaneously.
To the preferred embodiment shown in Figure 3, stop component 28 has been described at Fig. 1, and it has been envisioned for a simple circle annular with unified rectangular cross-sectional shape.In another embodiment of the present invention (Fig. 4,5 and 6), stop component 55 can have widened section 56.As shown in Figs. 4-6, the ratio that can judge widened section has some to amplify, and the axial length that can expect widened section approximately differs the 10-20% of the whole axial length of stop component greater than the axial length of widened section not.For example, one not the widened section axial length be the stop component of 8mm, its widened section axial length can be 10-12mm.In addition, though preferably about 90 to 100 ° of the circumference radian that each widened section of stop component comprises if wish, also can adopt less radian.More preferably, two widened sections 56 are set on stop component 55, and radially relatively are arranged on the stopping device 55.Widened section will be subjected to the axial constraint of flange 17 or 18 respectively.In addition additional widened section can be set, they preferably are provided with radially symmetrically round the stop component circumference.Only widen in the direction of axle, and on the stop component radial thickness of this widened section preferably with widened section identical (being like this when being in axial uncompressed state at least) not.Though used such as the stop component as stop component 55, can obtain the pivotal action of enhancing, in joiner, do not produce excessive axial " becoming flexible ".
In the another embodiment of the present invention (not shown), except or be not stop component 55 with widened section, flexible coupler apparatus also has one or two washer part with widened section.In another preferred embodiment, only widen along one axial " surface " of washer part.For example consult Fig. 5, suppose that object 55 has been replaced by a washer part, in this preferred embodiment, widen in a side of the symmetrical S face of or (best) two washer parts, and another axial surface remains straight.In such an embodiment, more preferably, the orientation of flat surface, making them with respect to connector apparatus, is axial outside surface generally, and the orientation on the surface of widened section, making them with respect to connector apparatus, is axial inside surface generally.They be that widened section will be towards the central authorities of joiner, and straight axle surface will be back to the central authorities of connector apparatus.Again in another embodiment, will on two axial surfaces of washer part, widen (this mode can with reference to the stop component 55 described in the figure 4 to 6).As mentioned above, any type of washer part with widened section all can use or replace having the stop component of widened section with the stop component with widened section.
In any other embodiment, stop component or, one or more washer parts all have widened section, so this corresponding stop component or washer part preferably are fixed on the inner piece 20 by any suitable method, as field welding, brazing filler metal etc.
In another embodiment of the present invention (Fig. 7), in device 10 ', pipe joint member 14 ', 15 ' has the flange 17 ' and 18 ' of radially outward diffusion.In part sectioned view shown in Figure 7, can see that shown section is the cross section that is used for representing parts such as tube end and pipe joint member thereof, in addition, described other parts are columniform basically.Pipe joint member 14 ' and 15 ' free end can be constriction as shown, can only be simple cylindrical parts as shown in Figure 1 also perhaps.Can use an exterior part 20 ' to replace inner piece 20, it circumferentially round at least a portion of pipe joint member 14 ' and 15 ' free end.Washer part 25 ' and 26 ', and selectable stop component 28 ' can be identical with those parts in described each example of Fig. 1 to Fig. 6, comprises that those have the different structure of widened section.If stop component 28 ' is set, usually may not request and do any type of fixing, keep its tram in the parts 20 ' outside, therefore the material that can be used to make stop component 28 ' (or stop component 28) is those materials that can make stop component 28 ' solid relatively (although some elasticity) at least, and this stop component has solid body.A slight radial compression can take place in stop component 28 ' when in addition, the size of stop component 28 ' was preferably made in its insertion exterior part 20 '.
The function that other connector apparatus 10 ' are had under compression, stretching, extension and beam mode is envisioned for Fig. 1 basic identical to mode shown in Figure 6.
