Description

For being releasably attached media lines or at least one media lines and at least one The connecting device for line of a component

The present invention relates to can be with for being releasably attached at least two media lines that medium can flow through or medium The connecting device for line of the media lines and component that flow through comprising: at least one inner chamber is used as fluidly connecting at least The flow path of two media lines or media lines and component and the medium for process；With at least one couplings Point, it is used to receive the male component that can be connected to or be connected to media lines, wherein in the region of coupling, it is interior Portion's chamber is dimensioned so as to, and is made it possible to work as and is inserted into male component and is locked in the coupling of connecting device for line At least one insertion space is provided when appropriate location for the excessive insertion of male component (over-insertion)；And conduit system System.

For being releasably attached --- that is, for connect at least two media lines that can be flowed through with separating medium or The attachment device of the connecting device for line or component of person's media lines and component is known in the prior art.Especially exist In the vehicles, media lines are provided for guiding liquid medium.Normally, connecting device for line is provided, especially with coupling The form of socket part point, for multiple media lines to be coupled or are combined together, wherein coupling and male component are mutual Connection.These connecting device for line are applied not only to interconnect at least two media lines, are also used to connect media lines and appoint Component of anticipating perhaps any component such as motor vehicle engine or pumps measuring unit into the region of motor vehicles water tank. At low temperature, why logical in media lines and connecting device for line is by the medium for freezing threat and being had the risk freezed The reason of often providing heating device for media lines and connecting device for line.Often those media be conducted through media lines and It is connected to its connecting device for line, due to relatively high freezing point, has tended to freeze in very high ambient temperature medium, The result is that function, --- functions of such as vehicles --- can be compromised or even be interfered significantly with.It should especially mention herein And aqueous solution of urea is as medium, is pumped through media lines and it is used as has the bavin of so-called SCR catalyst The NO of oil turbine_xReaction additives.It can be configured to SCR coupling or SCR male component in this connecting device for line, herein Locating these can also be used with the similar type of other media.SCR male component usually has circumference locating snap ring, is connecting It must be inserted into during coupling or the coupling of connecting device for line, until entering locating snap ring after fixing element Face is clamped in the state on coupling access component or part.For this purpose, so-called excessive insertion is needed, that is, about couplings The excessive insertion of actual lock position inside part or the part for entering coupling access component or partial inside, in order to make It is realized in the subsequent clamping of fixing element.Line of this tool there are two media lines is described in 20137083274 A1 of WO The example of road attachment device.

Medium inside media lines freeze or duration of coagulation, icicle accumulation may be migrated to catheter interior, Or it may cause increased the freezing of the medium --- such as aqueous solution of urea --- positioned at catheter interior.Aqueous solution of urea is Through freezing in the temperature lower than -11 DEG C.It is usually final in medium during the freezing of media lines or the medium being located therein The place freezed forms maximum pressure of freezing wall.Condensed medium expansion.Become the body of the result of solid from liquid as coherent condition Product, which increases, at least partly to be compensated, as long as the medium not yet freezed is present in media lines or is connected to its route In attachment device.In this case, condensed medium can be moved optionally in the direction of the medium not yet freezed, here this It is only possible, until establishing pressure balance.Elongated icicle usually can be moved only inside media lines, herein Locate this design, group of media lines and connecting device for line depending on media lines or the connecting device for line for being connected to it It the configuration of conjunction and depends on media lines or is connected to the sequence freezed of each region of its connecting device for line.

By media lines and the connection with the end between media lines and component or at them The duration of coagulation of medium inside the medium system of the component composition of device, the separation of one or more media lines and component Or tie point be specifically certified as it is especially problematic because inside connecting device for line under high pressure of freezing wall product Tired icicle can have such as a result, the icicle that can be grown of the male component for being inserted in there is from connecting device for line Coupling squeezes out, so that connecting device for line is connected with the plug of male component or coupling is discharged unintentionally.This More particularly to the long transmission line with 5m length, because especially big icicle can be accumulated in this long transmission line, very strong Pressure under can the direction for the release that male component is connected with the plug of the coupling of connecting device for line apply ice pressure Power, therefore plug connection can be caused to discharge from the coupling of male component and connecting device for line.

In order to solve this problem, for example, EP2455645A1 is proposed for connecting connecing at least two fluid media (medium)s Receive the pressure equalizing chamber between the first and second connection ends of the connector of element.Compressible insert is located at pressure balance In room.Compressible insert is on the inner wall that some regions are resisted against pressure equalizing chamber.For the first and second connection ends Between at least one the longitudinal room fluidly connected be provided at pressure equalizing chamber inner wall and compressible insert it.In temperature In the case where the volume expansion for spending the fluid media (medium) of induction, compressible insert is compressed.Pressure equalizing chamber is configured specifically To be cylindrical, similarly, compressible insert is configured as cylindrical.Pressure equalizing chamber is made of plastics.It is compressible Insert be it is reversibly deformable, here due to fluid media (medium) condense in volume expansion during its compressed, and Due to thawing, it uses its original-shape again during period, subsequent volume reduced.Therefore, compressible insert is by bullet Property material composition, be especially made of foamed plastics, such as closed cell foamed plastic.The surface of compressible insert is configured specifically For closure or the epidermis by being closed formed.Fluid media (medium) can be inserted from the first connection end of connector by compressible At least one the longitudinal room for entering object flow to the second connection end of connector.Compressible insert is as the time, may lost could Compressibility, this is because pressure balance in the aging of its material or the vertical passage even provided here in medium condensation The result of the damage of the compressible insert of chamber interior.Further, since equally in pressure equalizing chamber during the defrosting of medium End side connection region in dimensional measurement, connect fluidly connecting and can be present in pressure balance chamber interior between end The dielectric impedance freezed relatively long time.

Therefore, the purpose of the present invention is to further develop the connecting device for line of preamble according to claim 1, being used for can At least two media lines or media lines and component that connection medium in release ground can flow through, therefore even if do not provide pressure The male component and coupling of any damage and any connecting device for line to connecting device for line also can be effectively avoided in balance cylinder The unintentionally separation of socket part point.

For the attachment device of preamble according to claim 1, the realization of this purpose is because providing at least one Device --- it is in the intermediate state between mode of operation and frozen state, and medium flows through media lines during mode of operation (one or more) and connecting device for line, during frozen state, media lines (one or more) and connecting device for line Internal medium is frozen --- and reduce the volume of inner chamber and/or seals the component of inner chamber to prevent medium and/or ice Infiltration.This purpose is furthermore achieved by conduit system, which includes at least one this attachment device and extremely Few two media lines or media lines and component or component connecting device.Further exploitation of the invention be limited at from Belong in claim.

As a result, a kind of connecting device for line is provided, for being releasably attached, that is, for connecting and separating, medium can With at least two media lines that flow through perhaps media lines and component in the connecting device for line that medium flows through or passes through Portion provide its inner space or inner chamber be usually reduced as much as possible, especially by male component be inserted into connecting device for line with It is excessively inserting required for locating snap ring convenient for locking male component after the fixing element of the coupling of connecting device for line Space.In conduit system in the intermediate state between the operation under operating pressure, wherein medium flows through at least one medium and leads Pipe and connecting device for line, and the medium freezed in low environment temperature, that is, as at media lines (one or more) It can be use up with the critical zone of the medium ice formed in connecting device for line, the inner chamber inside inner chamber or connecting device for line Possibly reduce.In the correct time, the region can be reduced, that is, when after the mode of operation in remaining state, at this Freezing for interim medium may arriving.

Advantageously, because providing restoring means to reduce the volume in excessive insertion space, replace male component or At least one component of person, contacts or is connected to male component with male component relative to coupling, make in this way Excessive insertion space (one or more) is reduced, and/or provides device, in direction of insertion to male component applied force And/or it mutually opposes that the power acted on male component applies counter-pressure with direction of insertion.By male component and/or surround it Sealing element on power effect, in the front of male component and around the coupling of male component connecting device for line Internal excessive insertion space can be reduced such that cannot assemble medium there, otherwise fall below what medium freezed Medium, which may cause, when below critical-temperature mutually opposes that male component applies pressure with direction of insertion, and therefore due to when aggregation Volume expansion when state becomes solid from liquid, from coupling extrusion pin component.Excessive insertion space may be provided on slotting The front of the front end of head part may be provided on around it in the inside of the coupling of connecting device for line, and also On outside, around male component radially in the outside of male component and provide between the inside of coupling there with And prevent medium from the seal-packed axial direction of any leakage of coupling.There is described herein to reduce excessive insertion space or The measurement of at least one of person two excessive insertion spaces the two.These can be pure geometry, but can also be matched It is set in the form of the insert between male component and coupling, not only seriatim but also can be combined with each other and mention here For these measurements.Identical situation is suitable for the possible measurement for reducing the direct current space inside connecting device for line, directly Fluid space is that is, medium flow to another from a media lines or flow to the inside sky that component passes through from a media lines Between.

Advantageously, which is elastic device, especially spring element, rubber element or elastomer element.By means of This elastic device can move the sealing element provided inside coupling under any circumstance, for by means of the bullet Property device carrys out the intermediate space between the outside of sealing plug component and the inner peripheral wall of coupling, to be parallel to intercalation part Direction longitudinal of the part in its front end extends, so that setting between male component and the inner wall of coupling around male component The excessive insertion space set can also be sealed by sealing element, therefore these sealing elements can be located in excessive insertion space.By In the elasticity of sealing element usually provided, during the process of male component insertion coupling, especially in male component During excessive insertion, sealing element can be extruded, but as remove pressure when elastic device effect as a result, being back to it Original-shape is at least nearly to its original-shape or becomes compression shape.

Moreover, it is possible to apply the device of recuperability or restoring means axially acts on the locating snap ring of male component On, the side especially from the locating snap ring of the direction of insertion opposed orientation with male component, and in the coupling of connecting device for line The inside of socket part point is supported.As a result, male component can be extruded in the direction of insertion of male component in the axial direction, that is, It is axially squeezed into the direction of connecting device for line.Such as the element of isolation ring --- it is radially and/or axially It is supported inside coupling, and it is axially acted on spring element, especially applies pretension simultaneously --- it can It is used for support device, which applies recuperability, especially in the form of elastic element, rubber element, elastomer etc..Support Intercalation part is arrived behind the circumference locating snap ring that the elastic element on element or isolation ring is clamped in male component, and therefore The direction of insertion of part applies above-mentioned axial compressive force.As a result, male component can be extruded in its front end, that is, with stop Its opposite end of ring applies compressing force by elastic element on the locating snap ring, against the line for limiting excessive insertion space Inner wall in the attachment device of road, so that the front end of male component stops moving there.By this way, in male component The excessive insertion space that front end provides can be usually reduced as much as possible or male component can for good and all extend wherein, only Elastic element is wanted to act on male component.As a result, it is possible to be that only a small amount of medium can be retained in intercalation part In the remainder in the excessive insertion space of the front end of part.It is retained in medium therein therefore can only apply this small In compressing force to male component, so that being particularly due to the counter-pressure generated by the elastic element of there, it is not necessary that Huo Zheji Without any necessary worry the result is that squeezing out male component from coupling.

In addition, the device or restoring means of application recuperability may include at least two with the spring bullet being placed in therebetween The retaining ring of property element, which is arranged in a part of male component, especially in circumferential groove or with the straight of reduction In the part of the male component of diameter.The retaining ring in the direction of the fixing element of coupling is arranged in so as to be supported on coupling Another retaining ring on part, and on male component is supported on the protrusion relative to coupling.By two Elastic element is inserted between a retaining ring, elastic pressure can be applied in the retaining ring being axially supported on male component. After being excessively inserting male component, coupling is locked in the retaining ring that the side of the fixing element of coupling is upwardly oriented On.Elastic element can produce reaction force to resist the ice pressure to form medium icicle, so that it is extruded, as a result intercalation part Part is not extruded the inside of coupling.Due to the reduction of ice pressure, the recuperability of elastic element towards extrusion pin component into One stepping enters to be excessively inserting in space (that is, being moved axially in direction of insertion) and acts on.

It is verified it is further advantageous that pass through openings (through opening) shape that will be arranged in male component It is tapered as tapered.As a result, even if compressing force is preferably applied to the insertion of male component under the frozen state of medium On direction, that is, on the direction of the front end of male component, because due to the clear span or internal diameter of the pass through openings of male component Increased reduction, by the icicle that grows to its applied force on the direction of the front end of male component.Therefore it is excessively inserting empty Between can be reduced because male component is pressed into wherein.Therefore, any possible change is hardly assembled in excessive insertion space Obtain problematic ice.

In order to keep excessive insertion space as small as possible, even if being produced when opposite with the direction of insertion of male component by inner chamber When raw counter-pressure, other than the conical by its shape that the internal run-through of male component is open, can additionally it provide in direction of insertion Extrusion pin component gos deep into the elastic element described before inside connecting device for line.Therefore, elastic element support is by penetrating through Extrusion pin component caused by the conical by its shape of opening enters coupling.For example, can be determined for clear span it is tapered by The size of the thin internal run-through opening of gradual change, so that the clear span on the front end of male component is 1.5+/- 0.05mm and plug Clear span on the opposed end of component is 2+/- 0.05mm.

As further measurement, the inner chamber of the connecting device for line at least can have approximate suitable in part of It is opened in the perforation of (one or more) media lines and/or male component for being connected to or can be connected to connecting device for line The clear span of clear span at the outlet ends of mouth.Therefore, it is flowed through for medium so that the flowing is from a media lines to another The inner chamber of inside of one media lines or the connecting device for line to component can be smaller than pervious diameter, especially It only can have the identical clear span with the internal run-through of media lines and male component opening.Especially, it therefore closes at its end The inner chamber of the media lines of connecting device for line or male component or at least respective portion of inner chamber are connected at end Point can have 1.5 to 3mm clear span, preferably 2mm, here with media lines or its male component and its internal run-through The respective part chamber of register can be mixed mutually in the inside of connecting device for line.In the cross section of part chamber, Chamber can have the geometry as transverse portions chamber and the bigger clear span that obtains.

It is furthermore possible to also provide at least one sealing device is used to prevent medium osmosis from entering to be excessively inserting at least the one of space In a part.As a result, so excessive insertion space is not reduced, but medium osmosis is prevented to enter excessive insertion space In a part, so that can not assemble medium there, when the temperature of medium is down to its solidification point or less, medium may freeze Knot can apply ice pressure on male component.This sealing device can be arranged in, for example, the front end area of male component In domain, here the front end of male component or the preceding part of male component can have here with male component other Main body compares reduced outer diameter, and sealing element is added there.In this case, sealing element can be supported on On the outside of the circumferential inner wall of the coupling of connecting device for line, thus prevent from front be excessively inserting space medium into Enter the radial male component that surrounds to be arranged and be sealed by packaging the excessive insertion space axially limited, to prevent medium from line Any leakage of coupling in the inside of road attachment device.In addition, sealing device can be disposed in far from male component In the circumferential groove of the male component of front end, the front end portion of male component has than being added on sealing element here The bigger outer diameter in part.In such manner, it is possible to prevent any medium on the direction of the other end of male component from male component Front end is passed through, that is, in the second excessive insertion space being laterally arranged around male component.If sealing element is arranged On the front end region of male component, therefore the front end region of male component has reduction compared with the main body of male component Diameter, and be added to there, can be sized, so that it is aligned with the front end of male component.It can also be really Determine the size of sealing element and form it into, so that it is still in the wall for limiting the connecting device for line in excessive insertion space On.As a result, the wall thickness reduction by the circumferential wall of sealing element flows through path, so that only smaller space is available, Wherein medium cannot be assembled, and condensed medium can apply ice pressure.

Further prove advantageously be clamped in the locating snap ring of male component above and or below at least one is close The form of element is sealed, especially with o-ring and/or the form of type ring (form ring), configures sealing device.As a result, a side Face can surround the whole region of the locating snap ring of male component to plug relative to the inner wall of the coupling of connecting device for line Component is sealed.During the excessive insertion of sealing element or element, especially o-ring and/or type ring can be by flexibly Deformation, and during the second locating snap ring of especially male component removes pressure after the fixing element of coupling, It is easy to rebound again, that is, be back to its original-shape or at least partly stress reduction position.As with the shape of sealing element Between the inside of formula or the interpolation head part with the opening in the outside of male component and reception coupling wall Male component be arranged in outside at least one form sealing element this device as a result, can prevent medium from seeping Enter around male component excessive insertion space in because sealing element be disposed in it is in the excessive insertion space and close to its Envelope is to prevent medium from entering.Especially, sealing element can be disposed in excessive insertion space, so that when male component is inserted into They are compressed when in coupling, but after locking the second locating snap ring in the fixing element of coupling, they are at least Partly be released pressure, thus surrounded in the upper and lower side of the first locating snap ring itself and seal excessive insertion space prevent it is any Medium enters.

This at least one sealing device is advantageously supported in the inside of coupling and/or is kept with Anti-extrusion (falling out), especially by end bushing.By means of this end bushing, can be propped up in the inside of coupling Support this at least one sealing device.End bushing itself can be supported on pawl or other devices in the inside of coupling On.However, there are the risks that pawl will be broken off under ice pressure.Due to freezing compared with the non-frozen state of medium or The volume change of the medium freezed, so there is ice pressure or ice pressure.As a result, pressure area increases, thus this leads to coupling The more high load capacity of the coupling circle of socket part point.In order to avoid any shearing of pawl and the pressure of alleviation coupling circle, it is advantageous that End bushing is connected to coupling in a manner of securely connecting.For example, laser welding, friction or ultrasonic bond can be passed through It connects or bonds and the connection of firm connection is provided.Due to the connection of the firm connection of end bushing and coupling, generate now The distribution of ice pressure, so that the ice pressure for the male component for being applied to connecting device for line during the ice of medium is formed is passed It is handed to coupling circle, and the ice pressure for being applied to sealing device and end bushing acts on and is fastened on coupling in a manner of securely connecting On end bushing in socket part point.Due to the connection of coupling and the firm connection of end bushing, coupling may be implemented In male component higher retentivity.For example, the connection of firm connection can be formed as the weld seam of segmentation or be formed as Circumference, i.e., the weld seam not being segmented.Advantageously, end bushing is made of the material of impermeable laser, in order to be able to without problems It is laser welded to coupling.In addition, at least coupling can be made of the material of saturating laser, especially connecting device for line Or whole coupling access components that male component (one or more) can be inserted into can be made of plastics, the material of especially saturating laser Material.Due to the connection of the firm connection of end bushing and coupling, possible retentivity is higher or is likely to be simply equal to Couple the retentivity of circle.

It is further advantageous that male component can at least substantially be closed or be closed on end side, and have extremely The exit opening of a few side, the internal run-through open fluid communication with male component.Due to the provision of this side Exit opening or the exit opening of at least one this side are outwardly into route when medium is leaked out from the inside of male component Medium is deflected when the inner chamber of attachment device.As a result, freezing medium or medium icicle cannot arbitrarily penetrate into connection In the separation between the male component and coupling of device, and lead to separation and plug due to applying pressure unintentionally The connection of component.On the contrary, freezing medium prevents in this way, because of the initial off in this way exit opening of side, and therefore Prevent any medium from leaking into the inner chamber in the coupling of connecting device for line, because lesser volume ratio is those of larger Quickly freeze.

If the internal diameter of the exit opening of at least one side or the outlet of side are opened on the front end of male component The summation of the internal diameter of mouth is less than or equal to the clear span of internal run-through opening, then is proved to be especially advantageous about this point.Especially It is that the internal diameter of the exit opening of at least one side can be less than 2mm.For example, the size of the male component for 4 × 1mm, The internal run-through opening of male component has the diameter of 2mm.The size of 5 × 1mm gives 3mm generally also in automotive field Male component internal run-through opening diameter.In commercial vehicle field, the size of 6 × 1mm or 8 × 1mm are very common Size, the result is that internal run-through opening is measured as 4mm or 6mm.It is preferred that the internal diameter of the exit opening of side or net Width is less than the internal diameter of the pass through openings in the front end region of male component.Provided that the exit openings of multiple sides, then Its diameter can change, for example, the exit opening of side relative to each other can have identical diameter, deviate with from these The exit opening of the side of arrangement is different.Due to selection side exit opening internal diameter, can use flow media realize with Flow related throttling.It can have knot so by this throttling or volume reduction that provide the exit opening of side Fruit, that is, the medium being present in the exit opening of the side of male component --- such as SAE male component --- freeze first, and And it is pushed out to form icicle from connecting device for line.For example, in this case, than male component as previously described The pass through openings of tapered shape can have supporting role, because its diameter increases in the direction of media lines, so that icicle It easily can further be released from male component in this direction again.

On the outside of male component, male component can in the region of the exit point of the exit opening of at least one side It is configured as flat.In this manner, the reduction of the pressure loss of flow media may be implemented.Advantageously, the shape during leveling At edge is circular perhaps flat or avoids the damage of sealing element with inclined-plane, the sealing element is another Other places is added on male component to be sealed against inside the coupling of connecting device for line.

The exit opening of at least one side can prolong at right angular with the longitudinal direction of the internal run-through of male component opening It stretches substantially aligned.It is also possible that with the longitudinal axis of the internal run-through opening of male component or the longitudinal axis of male component at certain angle Degree --- especially obtuse angle --- arranges the exit opening of at least one side, and the pressure loss related with flow media whereby can It is reduced and is measured as preventative cavitation.In addition, the exit opening of side can be open from the internal run-through of male component To its outside linear extension and/or bending.

In addition to the complete end side closure that the internal run-through of male component is open, the front end and inside of male component Pass through openings are open in relation to can be configured to.In order to still be able to close the inside of male component in the case where freezing medium The front end of pass through openings, that is, there are the formation of medium icicle, at least one closing feature can be disposed in inside, that is, Internal run-through open interior.In this case, male component can have on leading flank is connected to internal run-through opening Exit opening and at least one closing feature for being arranged in internal run-through open interior, the closing feature are configured to pass through medium Icicle is removable and has spring, and provides the closing feature for forming medium ice in internal pass through openings The preceding exit opening of male component is closed during column.It can be by forming the mobile closing feature of medium icicle.It is used for substantially Fully or at least partially the internal run-through opening of end side closure male component or preceding exit opening.For this purpose, With formed the closing feature of icicle male component internal run-through open interior the front end of male component direction quilt To being pushed forward, and enter the exit opening of setting there, which can have opens with the internal run-through of male component Mouth compares reduced diameter, and closing feature is at least partially submerged in the exit opening.Especially closing feature about its shape and/ Or its internal diameter becomes to deform, and the exit opening being therefore arranged on the front end of male component is partially or completely pass It closes.The preceding exit opening of male component can with the internal run-through register of male component or be arranged to and male component Internal run-through opening longitudinal direction extend it is angled.

It can prevent medium icicle from seeping in this moveable closing feature of the internal run-through open interior of male component Penetrate into the coupling into connecting device for line.Freezing strength in the region of connecting device for line, especially single medium Conduit and/or to the burble point between the tie point of component to being increased significantly, for example, in regional traffic tool water tank Attachment device in it is identical.Therefore the previously described male component can be the attachment device of this vehicles water tank, that is, It is fixedly placed on vehicles water tank, here, for example, the coupling access component of the connecting device for line of connection media lines can It is connected to attachment device, for example, passing through insertion.As a result, producing connecting device for line, wherein connecting device for line is independent Component --- being herein the coupling access component of the male component of water tank and connecting device for line --- can be again by about each other It is mobile to be connected to form plug.Here, identical as what is had been described before excessive insertion can also be provided again, in order to Connecting device for line is fastened to coupling at the attachment device of water tank.

In order to generate connecting device for line freezing strength or improve connecting device for line another possibility is that Arrangement has at least one volume compensation element of sealing function on outside on the part of male component.Volume compensation element For acting on the volume compensation at the pressure medium on male component, for example, here so as to by the pressure that can be subscribed The limit energetically generates volume compensation.For example, this pressure limit can be 50 bars or more of pressure.In this case, body Product compensating element, can have about its axially extending extendible at least one portion, to generate volume pressure relative to medium Contracting, and the result is that volume compensation, is back to initial position when pressure stops here.Advantageously, therefore volume is mended It repays element and shows spring.For example, volume compensation element is by elastomer or solid such as metal material and elastomer Group is combined into, and metal material can be embedded into elastomer in this case.For example, volume compensation element is axially extendable Part can be configured to the element of sleeve shaped, and by being made of the material of spring, the material such as closed pore cellulose rubber Glue and/or its can be configured to spring, for example, for example, in wavy form.For example, elastomer can be EPDM。

Therefore, volume compensation element can be configured to a part or manifold, for example, two-part.At one In the configuration divided, the front end portion of volume compensation element can have biggish outer diameter and/or be configured as convex (protuberance-like) in order to provide maximum possible sealing area, thus during the operation of system --- that is, Make medium via the front end flow --- can be realized with can predefined pressure sealing and/or temperature range.In volume In the manifold configuration of compensating element, sealing ring, such as tetracyclic ring such as o-ring can be provided, is connected in route --- that is, when medium current through line attachment device --- also produces the sealing with specified pressure during the operation of connection device And/or temperature range.For example, this sealing ring can be accommodated between support ring in order in male component or component company The axial direction or longitudinal direction of connection device keep its position.The region of burble point between the route conveyed for fuel It is interior and provide what this volume compensation element was especially suitable in SCR (selective catalytic reduction) and cooling water.

Fig. 1 shows longitdinal cross-section diagram by being connected to the connecting device for line 1 of two media lines 2,3.Connection Device 1 is configured with the coupling access component angularly shaped of two couplings 10,30.What it was above adiabatic on the outside Encapsulation 4 surrounds, and two insulated package tubes of media lines surround, and is used as wavy pipe 24,34 in the configuration herein.This Outside, media lines 2 have other encapsulation 5 in the end of external insulation.Media lines 3 be inserted in coupling 30 and It is fastened to there.Media lines 2 are connected to male component 6 in end, which is inserted into connecting device for line In 1 coupling 10, and it is packaged both 4 and encapsulation 5 and surrounds, and is insulation.Male component 6 prolongs along its longitudinal direction It stretches with circumference locating snap ring 60, is inserted into coupling 10 in the region plug component 6.Circumference locating snap ring 60 is used for plug Component 6 is locked in coupling 10.Here, providing the end on connecting device for line 1 and in coupling 10 The fixing element of inside engagement clamps behind locating snap ring 60.In order to which male component 6 is locked in coupling 10, it is necessary to Inside of the circumference locating snap ring 60 until entering coupling 10 is pushed, so that due to the insertion slope provided in fixing element 7 70 after the initial withdrawal of fixing element 7, and male component 6 passes through locating snap ring, and the rebound of fixing element 7 enters coupling 10 Inside, and the return path out to locating snap ring 60 is blocked, and therefore block whole male components 6.Then, therefore stop Ring 60 is supported on fixing element 7 or on the part 71 for the fixing element 7 that the inside of coupling 10 provides.

In the insertion process, need so-called excessive insertion in order to push locating snap ring 60 to fully pass over fixing element 7 Or its part 71.This means that being excessively inserting the front that space 11 is provided at before the front end 61 of male component 6 simultaneously In the inside of the coupling 10 at place.In addition excessive insertion space 11a is provided in the region of sealing element 8,9, sealing Element 8,9 is circumferentially provided in the inside of coupling 10 for radially surrounding male component 6, in order to prevent medium It is leaked from coupling.Sealing element 8,9 is not provided, medium be possible to along male component from excessive insertion space 11 by into Enter to be excessively inserting space 11a to leak.Two sealing rings 8,9 are maintained at coupling by sealing element fixing element 80,90 Its position in the inside of part 10.Its all component 8,9,80,90 together forms sealed package.

Inner chamber 12 is provided in the inside of connecting device for line 1 the flowing road as the flowing of medium or channel Diameter.This is formed by two parts chamber 12a, 12b, two part chambers at point 12c be mixed with each other.Part chamber 12b is very short And generally include excessive insertion space 11.

This connecting device for line 1 can be provided, for example, stave or underfloor region in a vehicle In.By media lines 2,3 can with pumped (conveying) medium, for example, vehicle motor or there stoichiometric point and vehicle water tank or Between the pump of person there.Due to different temperature dominant at each point in a vehicle, to the medium used there The durothermic requirement of conduit is different, so that the media lines differently designed are connected to each other.This is particularly by route Attachment device 1 is completed.It, can be with according to the medium conveyed by media lines 2,3 and connecting device for line 1 in low temperature The medium for occurring being present in the inner chamber 12 of media lines 2,3 and connecting device for line 1 freezes.This can occur, especially For medium, for example, aqueous solution of urea orDuring freezing, since coherent condition becomes solid-state companion from liquid With volume increase, icicle gradually forms, and is moved to the inside of conduit system, or especially in the region for freezing to occur There are the places of high ice pressure further to gradually form.Therefore, if medium is present in the inner chamber 12 freezed there, Volume expansion and relevant high pressure (ice pressure) can have following as a result, male component is opposite with direction of insertion --- that is, The direction of arrow P1 --- it is squeezed out from connecting device for line 1.This is certainly undesirable, and will have in media lines The point occur leaking as a result, undesirably additionally from media lines and connecting device for line (one or more) The medium and optional other compositions for flowing through conduit system leak there.This should all be prevented under any circumstance.

For this purpose, the possible jelly in connecting device for line 1 according to fig. 2, in the inside of connecting device for line 1 Knot body product is reduced.Interior section chamber 12a and 12b have significant smaller compared with the connecting device for line 1 according to Fig. 1 herein Internal diameter or significant smaller clear span d_i.Clear span is passed through in particular corresponding to the internal diameter of media lines 2,3 or the inside of male component 6 Open up the clear span of mouth 62.The internal diameter or clear span d of part chamber 12a, 12b_iIt therefore can be, for example, 1.5 to 3mm, preferably 2mm. This flow section is enough that medium is guided to pass through connecting device for line.Critical zone in connecting device for line 1 is herein inside Therefore chamber 12 can be reduced significantly compared with shown in Fig. 1, and be therefore significantly reduced and divided as caused by ice pressure The risk being connect from connecting device for line 1 or its coupling 10 with the male component 6 of media lines 2.

Reduce excessive insertion space 11 in the critical zone of inner chamber 12 or springs back into its locking in male component 6 The further possibility kept after position is during the operation of conduit system --- that is, when medium flows through there When --- keep excessive insertion space as small as possible.This can realize that every kind of measure is all demonstrated by recovery by various measures Effect.One of possible measure is shown in figures 3 and 4.According to Fig. 3, the internal run-through opening 62 of male component 6 is configured as It is tapered to be tapered.This means that pass through openings, which have to be less than, to be connected in the region of the front end of male component 6 61 Diameter d in the opposite second end 63 of media lines 2₂Diameter d₁.For example, diameter d₁It can be for 1.5mm+/- 0.05mm simultaneously And diameter d₂It can be 2mm+/- 0.05mm.This taper of internal run-through opening 62 is as the movement in the medium freezed in inside Period elasticity or spring element.Assuming that media lines freeze from burble point, that is, it is outside from connecting device for line, and The ice formed by the medium freezed is mobile in the direction of connecting device for line from media lines, and basically this is problematic 's.By providing the tapered pass through openings being tapered, the mobile direction movement that can be used in excessive insertion space 11 of ice Male component.If the medium freezed moves the media lines 2 by being connected to male component 6, by male component 6 in plug The direction of the front end 61 of component, that is, from biggish diameter d₂Direction in lesser diameter d₁Direction, in the side of arrow P2 To male component 6 is pressed into excessive insertion space 11, so that only a small amount of ice is formed in excessive insertion space 11.In Fig. 4 It can be seen that the position for the male component 6 being pressed into excessive insertion space 11.Advantageously matched in the direction of the taper of pass through openings 62 It is set to from the end of male component 6 and is tapered, media lines are in the front end of male component 6 61 at the male component 6 Direction is connected or is connected to pass through openings 62.For example, plug can be completed by using two cores correspondingly shaped The formation of the tapered pass through openings being tapered of components interior.

In embodiment shown in Fig. 4, other than the tapered pass through openings 62 being tapered of male component 6, Elastic element 100 is provided inside coupling 10, is clamped behind the locating snap ring 60 of male component 6.For example, elastic element 100 can be configured to it is by spring element, rubber element, any elastomer or other elasticity or in the form of recovery.Bullet Property element 100 be located in the inside of swedged part 65 of male component 6 or the circumferential groove of male component 6.The institute in Fig. 4 In the illustrative embodiments shown, elastic element 100 is by isolation ring or support ring 101 in the end of male component 6 63 Direction is kept pre-.Elastic element 100 is for providing recuperability, in order on the one hand its front end 61 be utilized to support plug Component 6 is on the wall 13 in the excessive insertion space 11 being limited to inside connecting device for line 1, and reverse extrusion wall 13 makes It is as small as possible to be excessively inserting space 11, as shown in Figure 4.On the other hand, the recuperability of elastic element 100 is for there is pressure Resistance is flexibly provided, for example, the pressure occur be the freezing medium due to being gradually formed in chamber 12 icicle so that icicle It does not extend into or substantially in excessive insertion space 11.If male component is by its front end before as described in Fig. 3 Portion 61 is pressed through the tapered pass through openings 62 being tapered, and the compressing force by being applied by elastic element 100, so that Its wall 13 for colliding connecting device for line 1, medium osmosis enter excessive insertion space 11 and obtain stringent control.Pass through the party Formula can also have the second excessive insertion space 11a of larger diameter to avoid medium by entering outside male component 6.In Fig. 4 Shown in embodiment, this is arranged to be excessively inserting space or chamber.Only the front end 61 of male component 6 is excessive It is abutted against in the region of insertion space 11a on wall 13.However, also or assume alternatively that excessive insertion space 11a pass through elasticity The effect of element 100 or another elastic element is closed, therefore elastic element acts on male component 6 in a manner of squeezing And/or on sealing element 8,9, so that elastic element starts on the wall 13a of the coupling 10 formed there.This is scheming It is simplified and shows in optional embodiment in 10 and Figure 20.Figure 10 a shows compressed-bit of the sealing element under operating pressure It sets, depending on the system operating pressure can be 3,5,8 or even 13 bars, and sealing element especially elastic element 100.? In Figure 10 and 10a, on the static wall 13a for leaning against coupling 10 of sealing ring 8.For example, with the shape of spring element or elastomer The offer elastic element 100 there of formula squeezes two sealing rings 8,9, and also squeezes that be arranged in these solid with sealing element Determine the sealing element fixing element 80 between element 90, sealing element fixing element 90 supports sealing ring 9 in the direction of wall 13a, Sealing ring 8 and sealing element fixing element 80 are also supported, the result is that excessive insertion space 11a is minimized.All element 8, 9, it 80,90 contacts or communicates with male component 6.Because elastic element 100 is configured as springy or can reset, and And therefore can be realized resetting in a manner of identical with compression, male component 6 can be easily excessively inserting, in order to subsequent The desired locations being locked in the inside of coupling 10.Due to the effect of springy elastomer 100, but male component with It is maintained at the low position inside coupling 10, afterwards in order to reduce excessive insertion space 11.Additionally or alternatively, it is Effect of the sealing ring or sealing element that the external sealing of male component inside coupling 10 provides in elastic element 100 Under be extruded, travel further into inside coupling 10 so that excessive insertion space 11a minimize.

In the embodiment of the connecting device for line 1 with coupling 10 and male component 6 shown in Figure 20, instead of Sealing element fixing element 90 provides the fixing element 91 of moveable ring or sleeve shaped inside coupling 10.Its The flange portion 92 of circumference with the inside for protruding into coupling 10.It is used to limit removable in coupling 10 Ring or sleeve shaped fixing element 91 movement.For this purpose, flange portion 92 can with inside coupling 10 The stopping edge 14 of formation cooperates.Elastic element 100 in the form of spring element is supported on moveable ring or sleeve End in the fixing element 91 of shape, either more accurately in moveable ring or the flange of the fixing element 91 of sleeve shaped It is opposite with the possible contact zone 93 of flange portion 92 on part 92, there is the fixation for stopping edge 14 using flange portion 92 The position shown in Figure 20 of element 91 can contact or be in contact with it with possible contact zone 93.Using its opposed end, The elastic element 100 of spring element form is supported on end bushing 94, which also is disposed on coupling 10 It is internal.End bushing 94 is supported on inside coupling 10 on pawl 95, which protrudes into coupling 10 Inside, as also shown in Figure 20.In the embodiment shown in Fig. 20, at least when male component 6 is located at excessive insertion position When setting (as shown in Figure 20), the circumference locating snap ring 60 of male component 6 is stopped on the side of end bushing 94, and with spring element The elastic element 100 of the form of part is opposite.

In the illustrative embodiments shown in Fig. 4, two ways cooperation is to be inserted into coupling 11 in male component 6 In after reduce excessive insertion space 11, that is, the tapered internal run-through opening 62 being tapered, since internal ice moves It moves it and male component 6 is squeezed into such as coupling 10, that is, in the direction of arrow P2.In addition, passing through the effect of elastic element 100 Perhaps 11a is reduced here when ice is formed and is squeezed into from the direction of inner chamber 12 or 12a in excessive insertion space 11 When being excessively inserting in space 11 to reduce excessive insertion space 11 as much as possible and thus reduce marginal space, elastic element 100 also have supporting role, since freezing medium will form ice in the marginal space.Forming ice under such pressure cannot It enough re-forms, so that the pressure is from 10 extrusion pin component 6 of coupling.

In the embodiment shown in Fig. 5 and 5a, it is not only the internal diameter or net of the chamber 12 inside connecting device for line 1 Width is strictly reduced, identical as in embodiment according to Figure 2, and has additionally provided elastic device 110 comprising Two retaining rings 111,112, elastic element 113 is mediate.Elastic element is kept ring 111,112 two ends and is placed in Side.Entire elastic device 110 be disposed in the outer circle circumferential groove 66 of male component 6 or male component 6 a part In, which has reduced diameter compared with the remaining main body of male component 6.Retaining ring 111 is propped up on coupling 10 Support is in the interior section 71 of fixing element 7, while retaining ring 112 is supported on male component 6, and optionally also close It seals in element fixing element 90.Therefore, for locking the excessive insertion of male component 6 or retaining ring 111 in fixing element 7 It is easily possible (dotted line position of the male component 6 in Fig. 5 a).The position of male component 6 in operational state, that is, Latched position has been shown by a solid line in Fig. 5 a.Due to elastic element 113, after the excessive insertion of male component 6, male component 6 are maintained at excessive insertion position, so that being excessively inserting space 11 and being optionally also excessively inserting space 11a can be kept It is as small as possible.

Fig. 6 and 7 shows another possibility in the excessive insertion space 11 in the region for reducing the front end 61 of male component 6 Property.In Fig. 6 and Fig. 7 the two, it is provided in the preceding part 67 that the male component 6 of the front end 61 of male component 6 is transported in end In the respective outside diameter d for having and reducing compared with other outer diameters of the main body of male component 6₃Case in.Both Fig. 6's and 7 In embodiment, sealing element 120 or 121 is provided on the preceding part 67 of male component 6.According to the sealing of Fig. 6 member Part 120 extends herein, so that its end 122 or its extreme circumferential edge are substantially aligned with the front end 61 of male component 6, However, being extended fully into excessive insertion space 11 according to the sealing element 121 in the embodiment of Fig. 7 and abutting against restriction On the wall 13 in the excessive insertion space 11 inside connecting device for line 1.Here, the distal opening 123 of sealing element 121 has Size, so that opening width is less than the outside diameter d of the preceding part 67 of male component 6₃, so that the sky that the medium that can be used for there freezes Between can be further decreased.Both sealing element 120 and sealing element 121 by such as foamed material elastic material shape At, make in this way for 6 male component 6 in 10 internal lock male component of coupling excessive insertion still Possible, but simultaneously because respective sealing element 120 perhaps 121 media can only flow into small area or small In space.Even if there is freezing medium, ice pressure can not be too high there, so that it squeezes out intercalation part from coupling 10 Part 6.On the contrary, medium does not enter back into excessive insertion space 11a due to being sealed by respective sealing element 120 or 121 In, so that It is not necessary to also reducing the space of there.Naturally, for example, as shown in Figure 10 by providing another elasticity member It is substantially possible to reduce excessive insertion space 11a for part.

Fig. 8 and 9 each illustrates the embodiment of the improved connecting device for line 1 compared with the variant in Fig. 6, wherein close Envelope element 130 is also provided in the forefoot area of the male component 6 around male component 6 in part 68.However, being different from root According to the preceding part 67 of Fig. 6 and 7, the part 68 with reduced outer diameter is not disposed at the end 61 of male component 6, but with At a certain distance from it has.The front end portion 64 of another aspect male component 6 has identical with the remaining main body of male component 6 Outside diameter d_a.Only part 68 has reduced outside diameter d_a.It is not interfered into the stream in excessive insertion space 11 by sealing element 130, But the medium flow field entered in excessive insertion space 11a is interfered.This is in the direction of insert ends 63 by two sealing rings 8,9 volumes Other places sealing, it is fixed which is coupled to two sealing element fixing elements 80,90 inside part 10 again.

Different from the embodiment according to Fig. 8, in the embodiment according to Fig. 9, sealing element 8,9 and sealing element Fixing element 80 is omitted.Sealing element fixing element 90 is merely provided, and therefore excessive insertion space 11a is configured as It is very big.However, avoiding any medium by providing sealing element 130 in the region of the part of male component 6 68 and seeping It penetrates into excessive insertion space 11a, so that medium can only enter in excessive insertion space 11 and may freeze there.But It is that the ice pressure formed there is typically not enough to outside extrusion pin component 6 to coupling 10.

In the embodiment according to the connecting device for line 1 of Figure 11, other than sealing element 8,9, provide another Sealing element 81, two of them sealing element 8,81 contain the circumference locating snap ring 69 of male component 6 between them.It is close herein It seals element 81 to be located in excessive insertion space 11a, the wall 13a provided there inside coupling 10 can be especially provided On, and therefore minimize strictly the excessive insertion space 11a of there.During the locking of male component 6, due to close It seals element 8,81 and surrounds locating snap ring 69, thus realize sealing simultaneously, here due to the elasticity of sealing element 8,81, these tools There is revival, and result, when power works, they are back to its original position repeatedly.Be sealed in two sealing elements 8, The positioning of locating snap ring 69 between 81 can be located at from the locating snap ring 60 on its part 71 of fixing element 7 or coupling 10 At a certain distance from keyed end, therefore male component 6 can be than being normally latched or being locked in fixing element for circumference locating snap ring 60 At the position being further inserted into coupling 10 needed on 70.Dotted line shows the position of male component 6 in operational state It sets, wherein medium is carried through conduit system under pressure p, herein according to system and acts on the power on male component 6 F, pressure can be 3,5,8 or even 13 bars.The position for the male component 6 that solid line indicates shows the position of not operating pressure It sets, that is, home position, wherein the medium being located in media lines not yet freezes still then to freeze and volume is subtracted in advance It is small.

As shown in Figure 12, instead of two sealing elements 8,81, the sealing element of single form can be provided, sealing member Part is similar to coil main body in Figure 12.Formation sealing element 82, which can be provided that, to be supported in sealing element fixing element 80, and It is not on sealing element 8 and 81, in order to provide ' locked ' zone for the locating snap ring 69 of male component 6.Instead of shown in Figure 12 Formation sealing element 82 embodiment, different shapes can also be provided, one side can be realized male component 6 only The locking of rotating ring 69, and on the other hand can be realized sealing of the male component about coupling 10, to prevent fluid stopping through plug Any medium of component and chamber 12 enters another from a media lines, as illustrated in figs. 11 and 12.Not only in Figure 11 and 12 In the sealing element fixing element 90 that also shows in other figs. each be used for pre- installation of sealing element, it is especially close Seal element 9 and further sealing element 8 or 8 and 81 or 82.In this connection, according to the embodiment party of Figure 11 and 12 Formula, it is also possible to additionally provide spring element or another elastic element is used to open plug in advance in the direction of wall 13 or wall 13a Component 6, the wall 13 define excessive insertion space 11, and wall 13a defines excessive insertion space 11a.Due to this pre-, coupling The axial gap of male component 6 in part 10 is reduced, and therefore can be used for medium inflow space be significantly reduced or Person is additionally full of by male component 6 completely.

If icicle gradually forms in media lines and therefore in the connecting device for line for interconnecting these, Due to the taper of 6 pass through openings of male component, the mode for the male component being adjusted axially inside coupling can be provided.It is transporting Between the departure date, that is, when medium flows through male component under stress, this can use the axial position different from stationary state, Male component is not passed through in the stationary state medium.Due to connecting in the tapered pass through openings being tapered of direction of insertion in route The direction of wall 13 in the coupling 10 of connection device 1, this extrusion pin component 6 enter excessive insertion space 11.

Therefore, compared with coupling, male component uses the position different from stationary state in operational state, Here mode of operation and freeze between stationary state intermediate state excessive insertion space 11 or 11a be minimized.Such as Fruit provides spring element or another elastic element or elastic device, this provides to react on and gradually form in the medium Icicle ice pressure.Due to the elastic element or elastic device described before, especially with spring element, rubber element or The form of person's elastomer element, can be to the icicle gradually formed or the ice pressure from icicle provides resistance, so that excessively Insertion space is not filled with ice, and male component 6 is not squeezed out from coupling 10 intentionally.Maximum cheap offset appears in height In the various situations that pressure p provides, medium freezes to occur only at when system seizes up, and pressure medium is slow here Reduce, and the spring of elastic element works with the contrary of pressure no longer applied.

If starting from the internal diameter of the media lines of insertion connecting device for line, or the coupling of insertion connecting device for line The clear span of the internal diameter of the male component of partial media lines, media lines or pass through openings passes through connecting device for line 1 Inner chamber 12 in male component be continuous, and two continuous part chamber 12a, 12b are mixed there, this generates The available much smaller volume of medium, medium can freeze in the volume, so that ice growth and negative effect --- in order not to Desirably from coupling extrusion pin component --- it can be cancelled with this method.In order to make the medium inside connecting device for line It can also help to solve the problems, such as or can solve in medium by the diameter of the chamber provided or this reduction of clear span Ice formed in the case where unintentionally from coupling squeeze out male component the problem of.
