On one hand, the common supporting plates 8 are guided or centered by the ring plates 7 during a lifting movement, and on the other hand, the common supporting plates 8 are pressed by the springs of the ring plates 7 in two directions, which is particularly favorable for the nonuniform wear of a sealing surface and is favorable when the supporting plates 8 are stuck to the collector 4.
Description
The present invention relates to a kind of annular valve, in particular for compressor, it is provided with: a valve seat with the annular pass that is used for controlled medium, be provided with flow pass and be arranged in the slip ring at one segment distance place, valve seat top, and be installed in a valve plate between slip ring and the valve seat, this valve plate comprises each annular slab of being arranged on valve base channel top and one by pressing spring-loaded of slip ring and be bearing in common support plate concentric with respect to valve seat on all annular slabs, and therein the relative valve seat of annular slab by leading.
The annular valve of type is for example known by EP-A-345245 like this, and is particularly useful for the automatic control that air compressor or compressor are made load variations.Wherein the fundamental function of valve plate is support plate on the one hand, is each annular slab on the other hand, so these two elements can be as far as possible by perfect for the function that is realized by them.The annular slab that is configured single-piece can do to have enough big soft or contractibility and elasticity, so that guarantee be arranged on valve seat on respective surfaces form cooperating of sealing, realize the safe and reliable sealing of valve base channel, support plate can make suitable hard in contrast, for use in transmitting as far as possible equably and distributing spring force.
In order to make each annular slab radially lead or center with respect to the passage of valve seat, in described known device or the circular cone sealing surface is being set on the support plate and corresponding opposite is set on annular slab, or the depression of concentrated nose or groove shape is set on support plate, place ring part therein or make ring part and the support plate collaborative work.Even under the situation of the matching trim of bigger stroke and plane configuration, do not worry influencing the inclination and the displacement of the annular slab of valve function thus yet.
Task of the present invention is: the annular valve that begins described type is transformed, so that enlarge possibility of its application in simple mode, reach the reliably working that on different installation positions, guarantees valve, even when the difference wearing and tearing of each annular slab, also can guarantee the reliably working of valve.
This task will solve on the annular valve of described type in this wise according to the present invention: annular slab is by means of being bearing on the support plate with the irrelevant spring part of valve plate.Thus in order to realize opening fast of valve, that this is spring loaded and have additional inertial mass support plate, with by the top that certain distance that the additional springs part provides is placed on each annular slab is set, can therefore not lose the possibility that makes each annular slab guiding or center, also can get the restriction that the installation position that does not make annular valve is subjected to the annular slab of horizontal positioned because otherwise the annular slab of freely placing in valve relatively passage understand slippage certainly or drop out.This independent spring part can freely selected in the scope aspect its structure and the layout widely, compares by the common spring-loaded of support plate with all annular slabs, just allows the different possibility of trying one's best of acting force of the spring being divided retaining.Usually making a kind of like this selection under the various situations for each annular slab additional springs: when valve is opened at first be on the active force of the softer additional springs part of each belt plate opposing is elevated to attached to support plate always till, be only common spring then and whole valve plates played buffer function by support plate.
In a particularly advantageous configuration of the present invention, annular slab and support plate are provided with circular groove on its face face vis-a-vis, place the spring part that constitutes the ripple ring-spring in these circular grooves.For structure and the layout of these ripple ring-springs in circular groove, here for example can do like this: in normal working, the ripple annular spring is corresponding be located at each other directly with being compressed against annular slab and the surface of support plate between in the closed annular groove that constitutes, therefore only have leading role to each annular slab.When the annular slab irregular wear or support plate when being clipped in or being bonded on the slip ring, the effect of the additional springs power of corresponding ripple annular spring just can display.Can select the total height of ripple annular spring in this wise, promptly clamp and during in range, finish the task of guiding by the ripple annular spring at support plate.In order to guarantee the possibility of the two-sided use of annular slab, can circular groove all be set at two faces of annular slab.
In order to prevent that contingent annular slab from being inhaled on support plate, in another configuration of the present invention, be provided with suction port in the circular groove of support plate bottom, at least the size of unit annular slab is provided with one and goes suction port.
In another configuration of the present invention, annular slab is supporting spring part thereon in its guide portion that is provided with groove-shaped depression or projection on the face of support plate.This guide portion can adapt to the pattern and the layout of independent spring part very simply, for example can use corresponding single slotted eye or projection for single helical spring, so that guarantee centering and the insurance of rotation inhibiting of each annular slab.
Another particularly advantageous configuration according to the present invention, spring part is to be made of the spring pin that stoops from support plate.This spring pin can be impacted or with being laser-cut into, this just makes the manufacturing of the additional independent spring spare of accurate setting simplify.
Below the present invention is described in detail for the embodiment that will represent by means of part summary in the accompanying drawings.

Fig. 6 is the planimetric map according to a support plate of annular valve of the present invention, has the left and right not independent spring spare of isomorphism type; And
Fig. 7 is the another embodiment's axial, cross-sectional view of annular valve according to the present invention.
On the annular valve of all diagram patterns, all has the valve seat 2 that is provided with the loop configurations passage 1 that is used for controlled medium, have flow pass 3 at slip ring 4 and a valve plate 5 that is arranged between slip ring 4 and the valve seat 2 of being provided with at a certain distance above the valve seat 2, it is pressing spring 6 to load in the mode of generally showing by slip ring 4 in the drawings.Valve plate 5 have the single annular slab 7 of passage 1 top that is arranged in valve seat 2 and one common be positioned at all support plates 8 above the annular slab 7 and concentric with respect to valve seat 2, it is made as steel especially by hard relatively material usually, the power of spring 6 be evenly distributed in all normally by softer material as on the annular slab of especially doing for plastics 7, it all is on the sealing surface 9 of conical configuration here that this annular slab that is used in sealing channel 1 thus is crushed on.This sealing surface 9 can also have other suitable shape, especially plane configuration certainly in the scope of the invention.
The Fig. 1 that represents a configuration in the prior art has so far described a kind of possible valve collar structure, wherein when ascending motion valve collar without any guiding element, and only on closing position by the cone shape of Sealing 9 to the center.This annular slab 7 that can move freely with respect to support plate 8 in the valve open mode itself may produce maximum moving total S during therefore at range H.Thereby always must design annular valve like this: when range H, height t
2Should be less than the thickness d of annular slab, because otherwise annular slab is clamped, and on its closing motion direction, be obstructed and hindered the function of regulation.Obviously has shortcoming thus: if the trip H-is because of work reason may need the time-can not exceed the size by structure qualification.
Fig. 2 is to represent one by the known or derivative at least mode of execution of the described prior art of Introductory part corresponding to the mode of Fig. 1 basically.Here support plate 8 with annular plate 7 interactional zones in have around circular groove 10, it has degree of depth f and attached on the annular slab 7.The gap S1 that is used to limit relative movement possible between support plate 8 and the annular slab 7 on require to decide configuration.Because annular slab 7 on the one hand by go into flowing pressure, on the other hand by the defeating in circular groove 10 of spring 6, it can not drop out from circular groove 10 and also can be by leading when ascending motion.Therefore maximum Valve travel H can irrespectively be determined with other valve geometrical construction, in these valve geometrical constructioies especially to the size t that is put down in writing that reaches that Fig. 1 discussed
2When range H, need greater than ring thickness d.
Removing in being used to shown in Fig. 2 makes annular slab 7 with respect to common support plate 8 and outside the simple possibility mode that valve seat 2 centers relatively thus, certainly also has corresponding in addition simple possibility, promptly can with the change mode on support plate 8, be provided with around projection or analog, can entangle corresponding thereon by the annular plate of hole milling or boring, certain advantage so just is provided, can suffered damage because be positioned at the side contacts face or the inclined-plane used as sealing surface of annular slab downside in the drawings.Also can consider other mode of execution in addition, the locating stud or the analog that stretch out from support plate 8 wherein can be set, and be inserted in the corresponding hole on the annular slab 7.
In the configuration of the present invention according to Fig. 3 and 4, as only describing an annular slab 7 as shown in Fig. 1 and 2, this annular slab is by being bearing on the support plate 8 with another irrelevant spring part 11 of spring of unshowned whole valve plate 5 here.Annular slab 7 and support plate 8 they facing to the plane on be equipped with circular groove 10 ', placed the additional springs part 11 that structure is made the ripple annular spring 12 that centers therein, utilize it annular slab 7 is centered with respect to common support plate 8.Utilize the corresponding spaced radial between groove diameter and the ripple annular spring 12 to determine that maximum radial may amount of movement S.Whole height is selected in this wise, so that under the situation that support plate 8 clips, also will lead or centralized positioning to each annular slab when the stroke of maximum, so the no-load height of ripple annular spring 12 need equal the twice that Valve travel H adds groove depth t at least.The material thickness of ripple annular spring 12 itself is then less than the twice of groove depth t.
Remove and utilize ripple annular spring 12 to make outside effective guiding of annular slab 7 with respect to support plate 8, also has its advantage with this mode, promptly when annular slab wearing and tearing heterogeneous, each annular slab makes and itself will be pressed on valve seat 2 or the sealing surface 9 by the independent precompression of ripple annular spring 12.When the undisturbed proper functioning of annular valve, ripple annular spring 12 only play the guiding role, and at this moment the approximal surface of annular slab and support plate against each other.Only when the annular slab irregular wear or support plate 8 when being clipped on the not shown slip ring, the effect of the independent additional springs power of ripple annular spring 12 has just displayed.
As from Fig. 3, seeing, circular groove 10 ' can be arranged on the both sides of annular slab 7, so that this part can two-sidedly be used, inhaled on support plate 8 for fear of single annular slab 7, for each annular slab 7 at least the circular groove 10 of support plate 8 ' the bottom be provided with one and go suction port 13.
Remove outside the structure of illustrated and above-mentioned ripple annular spring 12, this ripple annular spring also can be such structure, promptly when the valve closed condition, be pressed between annular slab 7 on the sealing surface 9 and the support plate 8 and leave certain free clearance, so that opening when motion, support plate 8 temporary transient make when static annular slab 7 at first the little spring power of antagonistic spring spare 11 or ripple annular spring 12 upwards lift.Only when annular slab 7 by ripple annular spring 12 slow lean against on the support plate 8 after, the active force that this whole valve plate 5 is just resisted not shown spring moves to the slip ring direction.Reach thus and make valve open and obtain simultaneously reliable and effective buffering that whole valve plate is opened motion easily.
According to Fig. 5 to 7, spring part 11 directly is made of the spring pin 14 that stoops from support plate 8 separately between support plate 8 and annular slab 7, it here also be bearing in annular slab 7 structure on support plate 8 one sides do circular groove 10 ' guiding area on, also has above-mentioned advantage thus, promptly to the guiding or the centralized positioning of single annular slab 7, even also be so when moving upward, and the independent additional springs that annular slab 7 is provided.Its difference of embodiment according to Fig. 5 and 7 is in fact: on the annular slab 7 of Fig. 7, be not provided with any circular groove 10 '; As for spring pin 14 simply by on the upper surface that is placed on annular slab 7 whether for the guiding of annular slab or to center be enough, whether for example raised or sunken accordingly with spring pin 14 collaborative works perhaps is set on the position that spring pin 14 is placed, under individual cases, is determined easily or determines.
Described half of annular valve integral body and provided centre bolt 15 on Fig. 5 and 7, this bolt screws in and in slip ring 4 and valve seat 2 and by a nut 16 the full annular valve is linked together.In this case, put into a spacer element 17 between slip ring 4 and valve seat 2, it mills 18 pairs of valve plates 5 of platform or support plate guiding with one, can realize that thus they are in axial ascending motion.Also depict original valve spring in the drawings and represent it with label 6.
Last two kinds of modification in Fig. 6, can seeing spring pin 14 structures that stoop from support plate 8.Can see the monolateral tongue that is cut into earlier by laser in the figure left side, though it manufactures simply, the single annular slab that it is being pressed forms lasting rotation.For fear of this rotation, this spring pin 14 can make not shown annular slab 7 obtain the insurance of rotation inhibiting according to make the two tongues that are provided with shown in the figure right side on both direction thus.
