Description
Technical field
The present invention relates to a kind of interior valve of reception recess that inserts valve support.
Background technique
In the structure of hydraulic pressure installation, for example, in hydraulic pressure installation movably, use can screw in the valve in the reception recess of valve support usually.This valve is designed to one-way valve, and it derives from the data sheet (FLUTEC, Fluidtechnische Ger te GmbH, Brochure NO.5.175.2/7.95HYDAC catalogue 01 the 9th joint) of RV5E type FLUTEC one-way valve.This valve has the valve pocket that can screw in valve support.Valve is threaded in the valve pocket, is supported on the valve support up to the axle collar that forms on the valve pocket.The sealing surfaces that formation and closure combine closely on the valve pocket, thus entrance and exit is separated.Closure is arranged in the recess on the valve pocket, and is limited by elastic force.The sealing of the relative valve support of valve is subjected to the influence at the seal element that radially works, and these seal elements are arranged in the both sides of the exit orifice of valve pocket upper edge arranged radially vertically.
For the valve of being given, shortcoming is that valve pocket only is made of parts.Because the predetermined length of these parts is fixed, therefore need prevent because of receiving the leakage danger that recess manufacturing tolerances in the axial direction causes with the seal element that works diametrically.
Summary of the invention
The object of the present invention is to provide a kind of interior valve of reception recess that inserts valve support, the length overall of this valve can adapt to the specific length of installation that receives recess automatically.
This purpose is realized that by valve of the present invention valve of the present invention has the feature of claim 1.
According to the present invention, this valve has by first valve pocket part and can be connected to the valve pocket that second valve pocket above it partly constitutes.For this purpose, this second valve pocket partly can partly link to each other with first valve pocket by its first end.First valve pocket part is fixed on mounted valve in the reception recess of valve support.
First end of second valve pocket part forms a sealing surfaces, and this surface and closure cooperate, thereby forms the valve seat of sealing.On first end that first valve pocket partly is connected to second valve pocket part, total length that can regulating valve.Thereby can compensate the difference that receives on the recess length, this species diversity is inevitable in manufacture process.This can make second valve pocket part and the valve support of valve form sealing in the axial direction.
The method of listing in the dependent claims relates to some favourable improvement that valve of the present invention is done.
Specifically, it is favourable forming connection by the pressure fitted ways of connecting between first valve pocket part and second valve pocket part.Like this, insert the reception recess and just accurate length can be set directly.In receiving recess the time, second valve pocket part is just pushed automatically or is shifted onto on first valve pocket part with the first valve pocket partial fixing.For this reason, second valve pocket partly is supported on the respective surfaces of reception recess of valve support.Meanwhile, between second valve pocket part and valve support, form sealing.
In addition, it is favourable forming supporting surface on first valve pocket part, and according to further favourable structure, this supporting surface receives axial seal.(for example being connected by spiral) the whole valve that assembles so in advance can insert the reception recess simply on valve support if first valve pocket partly is fixed, and screws in, and is supported on the valve support up to supporting surface.In this process, second valve pocket part is pressed into simultaneously or is pressed onto on first valve pocket part.
According to another preferred embodiment, pressure fitted connects the zone design that form by two mutual in the axial direction skews and becomes first pressure fitted and second pressure fitted, both radial length differences.This step type pressure fitted helps second valve pocket is partly inserted the first valve pocket part.Here pay the utmost attention to form between first pressure fitted zone and the second pressure fitted zone, be arranged in conical transition section on first valve pocket part and second valve pocket part respectively, this changeover portion can be simplified the pre-assembling of valve.In being inserted into first valve pocket part, second valve pocket partly can certainly be pressed onto on first valve pocket part.For simplifying narration, only narrate second valve pocket below and partly be forced into the interior variant form of first valve pocket part.
Pressure fitted can be done following design, or surpasses available maximum compression distance, obtains constant compression force, or pressure increases with the increase of compression distance.For this purpose, one of them zone on first valve pocket part or second valve pocket part is designed to taper shape.In case the insertion valve, another valve pocket part will be forced to take place plastic deformation, and this can promote the connection between first valve pocket part and second valve pocket part, and also be particularly advantageous from connecting durable viewpoint, so doing.In addition, therefore the seal action between second valve pocket part and the valve support can improve.
In order to check compression distance, preferably on second valve pocket part, form mark, can check the relative position of relative in the axial direction first valve pocket part of second valve pocket part by this mark.Also can form stop surface on first or second valve pocket part and mark, this surface also can be determined maximum compression distance simultaneously.Exceed after this maximum compression distance, the total length of valve shortens because of another time plastic deformation.
Second valve pocket partly preferably has the inlet that passes it vertically, and therefore second valve pocket part can be made into simply, preferably be approximately cylindrical sleeve.For instance, although this sleeve is formed by high-quality material turning, particularly because it will form sealing with valve support, first valve pocket part also can be made by common material.

Embodiment
Fig. 1 shows the valve that assembles in advance 1 of first exemplary embodiment of the present invention.The valve 1 that assembles in advance in this way is inserted into subsequently and receives in the recess.Valve 1 comprises the valve pocket of being made up of the first valve pocket part 2 and the second valve pocket part 3.Connection between the first valve pocket part 2 and the second valve pocket part 3 can change the relative axial position of the second valve pocket part, the 3 relative first valve pocket parts 2, thereby can determine final total length L.
The inlet 10 that passes the second valve pocket part 3 vertically is by jar bottom lock of shape closure 4, so it was cut off with being connected of outlet 11,11 '.For instance, if hydraulic fluid 10 is supplied to valve 1 by entering the mouth, the pressure of this fluid just acts on jar bottom of shape closure 4 so.Act on the power that the hydraulic coupling on the closure 4 is just resisted pressure spring 5, therefore when it surpassed spring force, closure 4 just continued to move in central recess 6, thereby leaves sealing surface 9.
A bit of with when being connected on the first valve pocket part 2 in first end 7 of the second valve pocket part 3 is pressed into the central recess 6 of the first valve pocket part 2, second end of the second valve pocket part 3 (being the other end) stretches out the first valve pocket part 2.The total length L of valve 1 is forced into degree of depth decision in the first valve pocket part 2 by the length of two valve pocket parts 2 and 3 and the second valve pocket part 3.
The first valve pocket part 2 has three end to end in the axial direction section.In exemplary embodiment shown in Figure 1, screw head 12 at first is provided, be thread section 13 afterwards.By the outside thread that forms on this zone, the valve 1 that assembles in advance is fixed on and is used to receive in its reception recess.In the exemplary embodiment that provides, for being screwed into, valve 1 receives in the recess, on screw head 12, make hex hole 14.Except screw head 12 and hex hole 14, also can expect adopting any other common fastening piece.For instance, mention here and can use screw head 12 and hex hole.For instance, be not difficult equally to expect valve 1 to be inserted and secured in the reception recess with anchor clamps.
After thread section 13, on the direction of the second valve pocket part 3 sleeve shape section 15.On the direction of the opening end of the central recess 6 of the first valve pocket part 2, being arranged on this sleeve shape section 15 at first is outlet 11,11 '.Sleeve shape section 15 is radially passed in outlet 11,11 '.Also arrange first area 16 and second area 17 towards opening end.First area 16 and second area 17 cooperate with the respective regions of the second valve pocket part 3, connect thereby form pressure fitted.Explain with reference to Figure 4 and 5 that pressure fitted connects below and for this purpose and the geometrical construction that on the first valve pocket part 2 and the second valve pocket part 3, forms.
Mark 18 is provided on the excircle of the second valve pocket part 3, and it is used to check that the second valve pocket part 3 is forced into the degree of depth in the first valve pocket part 2.In exemplary embodiment shown in Figure 1, mark 18 forms the circular trough that is positioned on the second valve pocket part 3.In any case circular trough is preferably made, but except circular trough, also can carve or make other forms of mark with for example laser in the operating process of the turning second valve pocket part 3 that all needs.
In order to improve the unlatching performance, on the first valve pocket part 2, form another radial opening 19, this opening is produced on the sleeve shape section 15, and it exports 11,11 ' relatively vertically towards screw head 12 skews.Because therefore the existence of this radial opening 19 in the process of Open valve 1, pressure balance just occurs in the space of arranging closure 4 with between around the zone of sleeve shape section 15.The closure 4 that is arranged in the central recess 6 has running clearance.Valve one is opened, and the gap that forms between the wall of closure 4 and central recess 6 is flow through valve with regard to allowing from the pressure medium that central recess 6 is discharged.In this process, in pressure medium can be discharged to space around sleeve shape section 15 from another radial opening 19.
To open performance in order further improving, on the cylindrical region of jar shape closure 4, to make circular trough 20 in addition.As following when introducing Fig. 3, to explain, valve is pulled away by this circular trough 20 once opening the fluid of discharging.
In Fig. 2, receive recess 21 in order to explain, show the cross section of passing valve support 22.Receive recess 21 and be used to receive valve shown in Figure 11.Receive recess 21 and mainly comprise blind hole 23.In blind hole 23, on the zone of valve support 22 upper surfaces 25, make screw thread 24.The valve 1 that assembles in advance among Fig. 1 is inserted into and receives in the recess 21, and the thread section 13 of the first valve pocket part 2 is screwed onto on the screw thread 24 of blind hole 23.On the upper surface 25 of valve support 22, form shoulder 26, thereby be suitable for doing supporting surface to carry out the plane of axial seal in the formation on every side that receives recess 21.When determining the radial length of shoulder 26, allow the screw head 12 of valve 1 sink to wherein.According to the degree of depth of shoulder 26, screw head 12 is partly or entirely sunk in the shoulder 26.
Valve support 22 radially around the wall of blind hole 23 and be connected between the inlet pipe 27 of blind hole 23 bottoms and form changeover portion 29.Being shaped as radially of changeover portion 29 is tapered towards inlet duct 27, and this shape is preferably taper, and preferred formation in drilling blind hole 23.Changeover portion 29 must be selected the sufficiently high surface finishment of quality, thereby can realize seal action by contacting with second end 8 of the second valve pocket part 3.For this reason, the quality optimization of producing the material of the second valve pocket part 3 is higher than the quality of materials of valve support 22.Just as the material of valve support 22, the first valve pocket parts 2 also can be selected more suitably quality.
Valve 1 shown in Figure 3 is in installment state.As explaining in the statement relevant with Fig. 2, by thread section 13 is screwed in the screw thread 24, the valve 1 that assembles in advance just is inserted and secured on and receives in the recess 21.The total length of the valve 1 that assembles in advance is longer than the degree of depth of the blind hole 23 between shoulder 26 and changeover portion 29, and second end 8 of the second valve pocket part 3 can rest on the changeover portion 29.Like this, even before supporting surface 30 is supported on the shoulder 26, second end 8 of the second valve pocket part 3 has rested on the changeover portion 29.Also have circular trough 31 towards supporting surface 30, wherein place sealed member, be preferably O shape ring 32 at the opening end of the first valve pocket part 2.When supporting surface 30 contacted with shoulder 26, this O shape ring 32 was sealed and matched with shoulder 26.
For O shape ring 32 is contacted with shoulder 26, the second valve pocket part 3 at first must be pressed in the first valve pocket part 2, and this is that total length L for the valve 1 that will assemble in advance shortens to length of installation L '.In case be screwed into, required pressure is just directly produced by second end 8 that is supported on the second valve pocket part 3 on the changeover portion 29.On the excircle of second end 8 of the second valve pocket part 3, form sealing the margin 33.
By the second valve pocket part 3 is pressed in the first valve pocket part 2, not only original total length L is shortened length of installation L ', and has also produced sizable surface pressure simultaneously between sealing the margin 33 and changeover portion 29.Because compare the diameter of blind hole 23 with the external diameter of the sleeve shape section 15 of the first valve pocket part 2 bigger, therefore around the part of stretching out this sleeve shape section 15 of the sleeve shape section 15 of the first valve pocket part 2 and the second valve pocket part 3, form space 34.In the process of mounted valve 1, between sealing the margin 33 and changeover portion 29, produce seal action, after valve 1 is installed, have only when valve 1 is opened, just can connect between space 34 and the inlet duct 27.The valve 1 that only needs will assemble in advance simply is screwed in the reception recess 21, is supported on up to supporting surface 30 on the shoulder 26 of valve support 22, can realize seal action, and valve 1 is shortened length of installation L ' simultaneously.
About the total length of valve 1 each component, the automatic adjusting of length of installation L ' can compensate relatively large tolerance.After valve 1 was inserted into and receives in the recess 21, length of installation L ' was determined by the distance between the rum point of second end 8 of the shoulder 26 of valve support 22 and second valve pocket part.This length of installation L ' must be less than the total length L of the valve 1 that assembles in advance.Minimum length of installation L ' is that total length L deducts the second valve pocket part 3 and is pressed into maximum depth in the first valve pocket part 2.Therefore, even if not only not relevant but also encircle 32 relevant seal actions with O shape and seal the first impaired valve pocket part 2 of shoulder 26 places, also allow sizable manufacturing tolerances with the second valve pocket part 3 at changeover portion 29 places.
Shown in exemplary embodiment as shown, in another circular trough 31 at screw head 12 places, arrange also can form such groove 31 outside the O shape ring 32, for example, can between supporting surface 30 and shoulder 26, place flat sealing gasket.
The second valve pocket part 3 is pressed in the first valve pocket part 2, and pressure spring 5 can be subjected to prestressing force, and this is because closure 4 is further back in the central recess 6, and wherein closure 4 is on the sealing surface 9 of state lower support in the second valve pocket part 3 of pressurized not.The circular trough 20 that forms on the circumference of closure 4 just enters and another opening 19 position overlapped like this, so the unlatching performance of valve 1 can be subjected to positive influences.
For the valve 1 after the damping unlatching, the pressure mediums that are enclosed in the central recess 6 can be discharged by the gap that forms between closure 4 and the central recess 6.In case open, closure 4 just moves to the closed end of central recess 6, thereby reduce the rear at closure 4, the back space 6 ' that in central recess 6, forms.
In this process, with back space 6 ' to reduce consistent be that pressure medium moves along the gap between closure 4 and the central recess 6.Pressure medium is delivered in the circular trough 20 always, and flows in the space 34 by another radial opening 19.Gap size between closure 4 and the central recess 6 is suitable, so that obtain the required damping of valve 1, this damping reduces with the increase of closure 4 running clearances.
Therefore, open performance basically by used pressure spring 5 and act on jar end face of shape closure 4 and and determine through the pressure of inlet duct 27 supplies.
Because in the zone of screw head 12, and there is seal action in valve 1 by axial seal between sealing the margin 33 that forms on second end 8 of the second valve pocket part 3 and changeover portion 29, therefore also can remove other common radial seal elements from.Except reducing requirement, also can reduce the radial dimension of valve 1 to components accuracy.In addition, in each case, the different length of installation L ' for imagination also can use the first identical valve pocket part 2.The adaptability of different length of installation L ' only is subjected to the influence of the appropriate length of the second valve pocket part 3, because the geometrical construction of the first valve pocket part 3 is simple, the cost of therefore making it is not high.
Fig. 4 shows the local I V of Fig. 3, and it shows first example that the pressure fitted between the first valve pocket part 2 and the second valve pocket part 3 connects.As having explained when narrating Fig. 1, the place near outlet 11,11 ' on the sleeve shape section 15 of the first valve pocket part 2 forms first area 16.The corresponding external diameter of the first area 35 that first end, 7 places of the internal diameter of this first area 16 and the second valve pocket part 3 form coacts, thereby forms first pressure fitted.
The internal diameter of second area 17 that forms second area 17, the first valve pocket parts 2 in the open end of the first valve pocket part 2 is greater than the internal diameter of the first area 16 of the first valve pocket part 2.The second area 17 of the first valve pocket part 2 and 36 cooperations of the second area of the second valve pocket part 3, thus second pressure fitted formed.For this reason, the external diameter of the second valve pocket part 3 in the second area 36 of the second valve pocket part 3 is corresponding to the external diameter in the first area 35 of the second valve pocket part 3.In the first and second valve pocket parts 2,3 first area 16,35 separately and the first and second valve pocket parts 2,3 second area 17,36 separately in first pressure fitted and two diameter differences of second pressure fitted make pre-assembling easily.For this reason, the changeover portion between first area 16,35 and the second area 17,36 is designed to the first conical transition section 37 and the second conical transition section 38 respectively.Conical transition section 37 and 38 can prevent that the second valve pocket part 3 is firm once inserting 2 inclinations of the first valve pocket part.
The axial length of the axial length of the first area 35 of the second valve pocket part 3 and the second area 17 of the first valve pocket part 2 preferably equates, therefore the second valve pocket part, the 3 firm insertion first valve pocket parts 2 are assembled valve 1, the first and second conical area 37,38 in advance and are just made the second valve pocket part, 3 automatic centerings.
Another example that pressure fitted connects as shown in Figure 5.Compare with exemplary embodiment shown in Figure 4, have only first area 35 to be formed on the second valve pocket part 3, corresponding first area 16 forms first pressure fitted on this zone and the first valve pocket part 2.Yet conical section 39 is formed on the second valve pocket part 3, with the second area 36 that replaces the second valve pocket part 3.When only reaching a certain compression distance, this conical section 39 just cooperates with the second area 17 of the first valve pocket part 2.If the second valve pocket part 3 deeper is pressed in the first valve pocket part 2, the first valve pocket part 2 will broaden because of the second area 17 of the open end of the first valve pocket part 2 and deform so.
Fig. 6 shows second exemplary embodiment of the valve 1 ' that assembles in advance according to the present invention.Those elements that the element with among Fig. 1 among Fig. 6 is corresponding are represented with identical reference character.For fear of unnecessary repetition, omit description of them once more.
Second exemplary embodiment of Fig. 6 is being connected between the first valve pocket part 2 ' and the second valve pocket part 3 ' with the difference of first exemplary embodiment shown in Figure 1, below it is described in detail.In second exemplary embodiment, for the second valve pocket part 3 ' is connected on the first valve pocket part 2 ', sleeve shape section 15 ' in the first valve pocket part 2 ' also forms first area 16, and this zone cooperates with the corresponding first area 35 of the second valve pocket part 3 ', thereby forms pressure fitted.On the direction of the opening end of the first valve pocket part 2 ', after the first area 16 of the first valve pocket part 2 ', be second area 17 ', the internal diameter of the first area 16 of the relative first valve pocket part 2 ' of this regional internal diameter does not change.The excircle of the second area 17 ' of the first valve pocket part 2 ' is tapered towards the opening end of the first valve pocket part 2 '.
Since the first area 35 of the second valve pocket part 3 ', at the second area 36 ' that on the direction of second end 8 of the second valve pocket part 3 ', then radially broadens.This of the second valve pocket part 3 ' preferably is the second area 36 ' that taper shape broadens and extends vertically, up to mark 18 '.Mark 18 ' forms step radially in the exemplary embodiment that provides.This step radially not only can intuitively show maximum compression distance, but also is formed for stopping the stop surface of the opening end of the first valve pocket part 2 ' simultaneously.Therefore maximum compression distance is limited by mark 18 '.
Be preferably formed step radially, therefore the external diameter of the cylindrical second valve pocket part 3 ' in second end, 8 these zones is corresponding with the external diameter of the sleeve shape section 15 ' of the first valve pocket part 2 ' in first area 16.For pre-assembling, the first area 35 of the second valve pocket part 3 ' is introduced into described opening end, and the conically widening part in the second area 36 ' of the second valve pocket part 3 ' contacts with the opening end of the first valve pocket part 2 '.
Certainly, in the first or second valve pocket part 2 ', other zones of 3 ', also can provide conical area.Here crucial is firm being pressed into, and plastic deformation will take place the respective regions of another valve pocket part.
Compare with first exemplary embodiment, valve 1 ' the firm insertion that assembles in advance receives recess 21, when the second valve pocket part 3 ' was pressed in the central recess 6 of the first valve pocket part 2 ', plastic deformation just took place in the second area 17 ' of the first valve pocket part 2 '.The conical joint of the first valve pocket part 2 ' in second area 17 ' is preferably corresponding with the conically widening part of the second area 36 ' of the second valve pocket part 3 '.Therefore, in the time of in the second valve pocket part 3 ' is pressed into the first valve pocket part 2 ', will form the cylindrical outer profile that cylindrical second end 8 by the sleeve shape section 15 ' of the first valve pocket part 2 ' and the second valve pocket part 3 ' constitutes, up to mark 18 '.
Before the supporting surface 30 of thread head 12 is supported on the shoulder 26, if having touched, the opening end of the first valve pocket part 2 ' forms the radially mark 18 ' of step, the valve 1 ' that so further will assemble in advance is screwed into the surface pressure that can increase sealing the margin 33 places in the receiving groove 21 on the one hand, on the other hand, can produce plastic deformation in sleeve shape section 15 ' the weakest zone.As shown in Figure 8, in this process, two export the outwards distortion of connecting plate (web) that forms between 11,11 '.
15 ' the intentional outside plastic deformation of sleeve shape section can prevent that sleeve shape section 15 ' is once 4 obstructions of compression closure.The central recess 6 of sleeve shape section 15 ' forms cylindrical, and the outside of sleeve shape section 15 ' is in the connecting plate zone between two outlets 11,11 ', even before compression, prebuckling part is outwardly arranged also.Like this, even under the state of not load, the central axis of connecting plate is also outwardly-bent in advance, therefore under load condition, equally plastic deformation can take place along this direction.This just forms geometrical construction shown in Figure 8.
Compare with first exemplary embodiment, the advantage of second exemplary embodiment is the quality regardless of first pressure fitted between the first area 16 and 35 of the first valve pocket part 2 ' and the second valve pocket part 3 ', and sealing the margin 33 all can apply sizable axial force to changeover portion 29.So just can further reduce precision required when making component.Even the opening end on the radially step that is supported on mark 18 ' of the first valve pocket part 2 ' only also can to produce in the axial direction in order being at sealing the margin 33 with less relatively pressure and to produce the required power of surface pressure on the changeover portion 29.
In Fig. 9, valve 1 ' is inserted in the improved reception recess.Here, screw thread 24 backs are bottom cutting portion (undercut) 40 then, and this part has increased space 34.Outlet 11,11 ' and the wall of valve support 22 between bigger distance advantageous particularly here, the wall of valve support 22 is limited to space 34 in the zone of bottom cutting portion 40.This causes flow passage resistance to reduce apart from increase.The simple especially method of making bottom cutting portion 40 in receiving recess 21 ' is to mill out screw thread 24 earlier on valve support 22, afterwards, generates bottom cutting portion 40 in an operation.
Figure 10 shows the 3rd exemplary embodiment of valve 1 ' of the present invention.Compare the first valve pocket part 2 here with first exemplary embodiment " constitute by first portion 50 of shortening and threaded closure plug 50 ', wherein first portion 50 is arranged in the blind hole 23 fully.Fix the first portion 2 of shortening with threaded closure plug 50 ' ", threaded closure plug 50 ' is supported on the first portion 2 of shortening " end face 51 on.
Corresponding in all the other elements and first exemplary embodiment, and represent with identical reference character.
The basis of the 4th exemplary embodiment of valve 1 is second exemplary embodiment.The first valve pocket part, 2 are designed to two-part once more, in the first portion 52 of shortening end face 51 are arranged.Sealing plate 52 ' forms the second portion of the first valve pocket part, 2 , and on its supporting surface 30 ' the pressure side face 51, this plate is fixed on the upper surface 26 ' of valve support 22.
Figure 11 does not show the fixing of sealing plate 52 ', for example, can by twist, riveting or anchor clamps fix.When determining the length of first portion 52, preferably allow sealing plate 52 ' can form flat board.Under installment state, end face 51 is concordant with the upper surface 26 of valve support 22 when stopping.
In order to seal, a groove is provided on sealing plate 52 ', in this groove, arrange O shape ring 53, the upper surface 26 of the latter and valve support 22 is sealed and matched.
Represent with identical reference character with the element corresponding elements in second exemplary embodiment, no longer repeat here.
The present invention is not limited to exemplary embodiment as shown in the figure, but comprises the various combinations of each feature among the different embodiments.
