Description
Technical field
The present invention relates to a kind of radiator valve, it has a valve casing, a valve seat and a closure member.
Background technique
A kind of like this radiator valve can be from for example recognizing patent documentation DE 33 08 070 C2.In this example, valve seat is formed in the sleeve that can insert in the valve casing.A support that is used for closure member is inserted in this sleeve, and some part of this support also must abut on the inwall of center hole, and sleeve also is inserted in this hole.At last, also need to be screwed.In support, disposed a spring for closure member.Closure member has a closed head of wrapping up in a kind of sealing material outward.This closed head links to each other with a bar that imports from inserting member.
Verified for many years this valve is used on the radiator respond well, but its structure more complicated, and require a large amount of number of assembling steps.In any case be difficult to reduce production costs.Use is accompanied by the decline of mechanical property in many cases than cheap material, and for example, closure member has a kind of danger that can not keep its necessary orientation in valve.This causes the leakage between closure member and the valve seat on the one hand, and on the other hand, when valve is opened, may produce vibration, can bring tedious noise.If want to simplify or even also same problem can take place when omitting some parts.
Summary of the invention
Basic purpose of the present invention is to address this problem, so that a kind of valve that can make with rational cost to be provided.
The technological scheme of above-mentioned purpose is a kind of radiator valve, it has a valve chest, a covers for housing, a valve seat and the closure member that can regulate by an operator, its spy is characterised in that, in valve seat, be furnished with a pilot pin, valve seat is arranged on the inserting member that inserts in valve casing body and the covers for housing, and this inserting member and pilot pin are integrative-structure.
Adopt this solution, the load that acts on the closure member is changed.This pilot pin and closure member are bonded on certain point just, produce undesirable mobile danger at this point because the effect of main power exists closure member, thisly move or cause closure member to lose centering with respect to valve seat, and the result is the sealing variation; Or cause laterally and move, the result causes vibration.Otherwise this closure member is then maintained it exactly and will be kept on the position of its centering, that is, and and on valve seat.Because now pilot pin works with respect to the centering of valve seat for closure member or is influential at least, so the manufacturing of these all the other component of valve requires the work done just few, this is former then to be essential for maintenance centering.This has just reduced manufacture cost.Moreover manufacturing process is also fundamentally simple, because now few for the work that correct each other centering between closure member and the valve seat is required do when this valve of assembling.Because pilot pin is to insert in the closure member, so this centering is to produce automatically.
Valve seat preferably is arranged on the inserting member that inserts in the valve casing, and this inserting member and pilot pin are integrative-structure.This has the configuration that utilizes pilot pin.Therefore, the complicated mechanical machining operation on the valve casing has not just needed.Pilot pin just has been protected when making inserting member with respect to being centered in of valve seat.
This inserting member preferably is clamped between two-part of valve casing, promptly between a valve casing body and the covers for housing.This inserting member has promptly aligned with respect to valve casing thus, and pilot pin also aligns on the orientation of regulation and is fixedly placed in the valve casing as a result.Therefore, this measure make valve the assembling facility how.
In this embodiment, be arranged on the side of inserting member away from closure member be particularly advantageous to covers for housing.Obtained a kind of selection scheme of especially simply assembling in this way.At first be with closure member, then be that inserting member inserts in the valve casing, thereby pilot pin is extend in the closure member.When covers for housing was sealed, the assembling of valve had just been finished.Centering is actual to be that " automatically " thereupon realizes.
Pilot pin preferably is connected on the inserting member by the control arm that is arranged to a star, and each control arm continues and a spacing body, and inserting member utilizes this spacing body to be supported in the valve casing.Can guarantee that so enough big through hole passes through for heating liquid.It is found that at first, these apertures are between spacing body, so heating liquid can flow radially inwardly into inserting member.Secondly, it is empty that the aperture keeps between the valve casing arm, makes the heating fluid physical efficiency leave inserting member vertically once more.Because each all seems control arm and spacing body to arrange in one plane, so also less by the flow resistance of these parts generations.Spacing body and control arm also play the effect of liquid distributor simultaneously.
Closure member is a taper shape preferably, and is like this in pilot pin protrudes the zone of stretching at least.This pilot pin can protrude and extend in the closure member thus, in closure member enough free spaces must be arranged.If selected a kind of taper shape, this closure member can be designed to like this, and promptly in its tip, it does not protrude into outside the diameter of known closure member, so traditional control member can be worked, for example, stuffing box is such as everyone knows.Therefore, cone promptly have in inside enough free space for pilot pin with stretching into, rather than mistake enlarges the spatial requirement to the outside greatly.Moreover, adopt taper can also guarantee on closure member, to have a favourable stressed distribution.Can pass to closed area by the coating face of cone by the functional unit applied force, compare with the situation of the center-pole that only provides a band pancake closure member, the danger of run-off the straight action is little.
In this example, this cone preferably has several guiding that extend radially inwardly to refer to part, and it reserves a clearance spaces for pilot pin.Therefore this cone needs not to be solid, so it can keep lighter weight.This has just improved response characteristic.Moreover, adopt tape guide to refer to the structure of part, guiding refers to that the space is arranged between the part, has reduced the friction between pilot pin and the closure member.
In this example, guiding refers to that part preferably has platy structure.Therefore in the axial depth scope of defined, all can keep leading role.
Another advantage is the effect that pilot pin also plays the bearing of a pressure spring, and this spring makes closure member towards the direction biasing away from valve seat.Therefore this pressure spring also is arranged in the occupied space of pilot pin.It refers to that by guiding part fixes subsequently, prevents from laterally to move.This structure also makes assembling very simple.Just spring must be inserted in the closure member.Pilot pin one inserts, and spring promptly is fixed, and prevents to come off.
Covers for housing preferably is screwed on the valve casing body.This also provides a kind of scheme of assembling easily.
In a kind of particularly preferred useful form, inserting member is pressed against on the tapered wall of valve casing, if desired, a seal ring is arranged betwixt.Adopt tapered wall that two advantages are arranged.It makes inserting member automatic centering in valve casing, and utilizes and for example can just can obtain high surface pressure between inserting member and tapered wall by covers for housing being screwed into the less retention force that the valve casing body is applied, and it can make the liquid closed property raising of sealing.
At its end away from valve seat, closure member preferably is tapered to the cylindrical body of a minor diameter, and the latter stretches in the valve casing hole of valve casing, also stretches into a tappet that imports by a stuffing box in this hole.As mentioned above, this useful form has such advantage, promptly existing Effector, and for example the upper-part of traditional thermostat can be used to handle this closure member.Because cone just ends at before the valve casing hole, and closure member links to each other with a column part subsequently, so when changing Stuffing box, do not need extra measure, valve is from motive sealing.In this example, closure member is pressed further in the valve casing hole by the power of spring between inserting member and the closure member, be pressed against on the axial edge in valve casing hole up to cone till.In addition measure, for example extra sealing is unnecessary.When the material of cone than the material of valve casing what softer the time, valve casing, or edge more precisely, will snap in cone some, therefore will obtain fabulous sealing at this.Yet, when the material of the material of cone and valve casing the same hard or even when harder, sealing also can be guaranteed.
This valve casing hole preferably continues and becomes one is the aperture on border with the cylindrical wall, and cone has several boss in its outside, and the guide face parallel with cylindrical wall arranged on it.This cylindrical wall is to extend along the direction parallel with closure member moving direction.By above-mentioned boss, closure member can obtain extra leading role in valve casing.This being directed in a certain specific range of valve seat worked.Like this, closure member is locating to be subjected to leading role at a distance of 2 an of segment distance each other, and this has further reduced the possibility that tilts to rotate.In installation process, particularly under the situation that closure member has aligned with respect to valve casing, it has made things convenient for the follow-up assembling of valve.
On covers for housing, preferably provide the coupling arrangement of valve.Structure as the radiator valve of angle valve form can obtain by plain mode thus.Therefore heating liquid becomes fairly simple by the guiding of this valve.Certainly in this mode, realize three-way valve or arrange that in covers for housing other valve part also is possible.
Inserting member and/or closure member are preferably made with the spray casting part.In described useful form, but can use the plastic material of spray casting to make inserting member and closure member.Special shape can obtain by spray casting, otherwise only may obtain by the assembling of complexity.Adopt spray casting, cost of production can reduce significantly.
Description of drawings
Below in conjunction with accompanying drawing, the present invention will be described with reference to preferred embodiment, wherein:
Fig. 1 provides one first embodiment of a radiator valve; And
It is one second embodiment of the radiator valve of angle valve form that Fig. 2 provides one.
Embodiment
Radiator valve 1 comprises a valve casing, and it is made of a valve casing body 2 and a covers for housing 3.In valve casing body 2, be provided with an inlet linkage section 4 and an outlet linkage section 5.Flow passage between inlet linkage section 4 and the outlet linkage section 5 can be cut off by the seal area of a closure member 6 and the concerted action between the valve seat 8.
Valve seat 8 is arranged on the inserting member 9 that is not integral with valve casing body 2 and covers for housing 3 and constitutes separately.Inserting member 9 is clamped between valve casing body 2 and the covers for housing 3.For this purpose, in valve casing body 2, provide an annular wall 10, it tilts with respect to center line 11, that is tilts with respect to the moving direction of closure member 6.Therefore this wall 10 forms a longitudinal section with taper coating face.Inserting member 9 is in close proximity to wall 10 and is provided with, and has a seal ring 37 betwixt.
Inserting member has a plurality of legs 12, is 3 legs in this specific embodiment, utilizes them, and inserting member is supported on the covers for housing 3.Leg 12 is reserved enough space betwixt and is supplied water to see through and enter the inside of inserting member 9, and does not have tangible resistance.Leg 12 can also be used as guiding device.Covers for housing 3 has an annular boss 13, and it has the radially-directed effect to the leg 12 of inserting member 9.Although can allow certain freedom of movement herein, this structure also can make inserting member 9 with the location of precision preferably when radiator valve 1 assembles.
Also provide control arm 16 on inserting member 9, it extends radially inwardly.In this specific embodiment, these control arms 16 are radially inwardly to be formed with the continuity section that makes progress by leg 12.Control arm 16 is supporting a pilot pin 17 at the middle part, so pilot pin 17 passes valve seat 8.Control arm 16 is arranged to star, passes through so kept the water supply of sizable aperture betwixt.Pilot pin 17 extends with a predetermined length on the direction of axis 11.
Closure member 6 is subjected to leading role on pilot pin 17.
Closure member 6 comprises a head 18 and a body portion 19.Seal area 17 is arranged on the body 19.For this reason, this body has a circular groove 20, and seal ring 21 is inserted in this groove.Seal ring 21 is supported by a peripheral wall 22 on away from that side of valve seat 8.Yes on the one hand plays the effect that forms a sealing for seal ring 21.Yet it also is useful in the inexactness that different parts are produced in manufacture process aspect compensating.
When this valve uses under higher pressure, seal ring 21 is abutted on the closure member 6 more tightly suit.This can for example realize by vulcanizing seal ring 21 to closure member or be cast into a reinforcer in seal ring 21.At last, wall 22 also can have some through holes, and the corresponding projection of some of seal ring 21 can join in these holes.When seal ring 21 during with closure member 6 cast solids, seal ring 21 can be in the both sides of wall 22 all some.
Head 18 protrudes with a column part 23 and stretches in the valve casing hole 24.A tappet 25 that imports by a stuffing box 26 also stretches in this valve casing hole 24.Closure member 6 is with its column part 23, or more accurately, is the groove 27 on its end face, and is adjacent with tappet 25.In operation, tappet is regulated in a well-known manner by radiator thermostat top or other actuating element, has not just explained in more detail at this.
The diameter of column part 23 is less than the diameter in valve casing hole 24.Yet outside valve casing hole 24, head 18 extends taperedly.Therefore cone 28 is made with subsequently than valve casing hole 24 and wants big diameter.This cone is connected to head 18 on the body 19, has the form of the circular cone of a cylinder prolonged section 23 so whole closure member 16 is cone 28 forms or one at its head, and in its bottom one ring edge is arranged, and forms body 19.
Valve casing hole 24 is to an aperture 29 expansions, and changeover portion coats face 30 by a circular cone and constitutes.In the outside of cone 28, there are several boss 31 to distribute in a circumferential direction, its outer wall is parallel to the outer wall in aperture 29,11 extensions of promptly paralleling to the axis.11 motions because closure member 6 parallels to the axis, these boss 31 provide a specific guiding together with the wall in aperture 29, and all these all make assembling convenient.Measure that need not be extra, closure member 6 can centrally be installed in the aperture 29 basically.Boss 31 has an inclined-plane 36 on its top side, it matches with the space that is defined by circular cone coating face 30.Like this, having guaranteed on the one hand has bigger area of contact between the wall of boss 31 and cone 28, and parallel to the axis 11 motion of closure member 6 can not be subjected to the restriction of these boss significantly on the other hand.
In cone 28, provide several tabular guiding that extend radially inwardly and refer to part 32, and leave clearance spaces 33, pilot pin 17 just is arranged in wherein.Therefore guiding refer to part 32 with closure member 6 radial support on pilot pin 17, and only allow it that axial motion and theoretic closure member rotatablely moving with respect to valve seat 8 are arranged thus.
In aperture 33, also be furnished with a pressure spring 34, it is compressed in pilot pin 17 and closure member 16, or more accurately, thereon on the supporting surface 35 of Xing Chenging.In order to improve the centering situation of pressure spring 34 on pilot pin 17, also can an axially directed boss be set in a kind of unshowned mode, it extend in the pressure spring 34, and its external diameter is consistent with the internal diameter of pressure spring 34.
Inserting member 9 and closure member 6 can be made with plastic material with the form of spray casting spare.Plastic material can be selected in the present embodiment like this, and promptly this material should be softer than valve casing body 2 and covers for housing 3, yet also has needed rigidity and dimensional stability.Sealing function in the seal area 7 is then guaranteed by the seal ring 21 that inserts.
Such valve can be made with very simple mode with few step.
Closure member 6, spring 34 and inserting member 9 just need be inserted in the valve casing body 2 successively.Then can screw covers for housing 3, put a seal arrangement 14 therebetween, for example a seal ring.As preparatory work, only be the closure member 6 that band seal ring 21 need be provided, the inserting member 9 that band seal ring 37 is provided.With the exception of this, because the fact is that closure member stretches into valve casing hole 24 with its column part 23, the centering of component is automatic.Spring 34 is held by aperture 33 and receives, and is in guiding and refers between 32.The pilot pin 17 of the inserting member 9 of Cha Ruing is in the center of wall 10 simultaneously, then also stretches in this aperture 33.Final location provides by being screwed into covers for housing 3.At last, can be screwed into stuffing box 26, then radiator valve 1 has just been finished.
This structure also has some other advantage.In case when backing out stuffing box 26 under the situation that modulating valve has been installed, pressure spring 34 urges closure member 6 and lifts off a seat 8, that is, be resisted against on the axial inward flange in valve casing hole 24 until cone 28 till.Be formed with an edge 38 at this place, the wall of it and cone 28 forms a good sealing.If desired, this edge 38 can embed in the material of cone 28 slightly.Do not need extra sealing at this, this simplifies the structure on the one hand, and has improved the stability of operation on the other hand.
Moreover closure member 6 can align better now, and is in the center of valve seat 8, and this has very big benefit.In fact, closure member is controlled tightly, and the power that flows through liquid that acts on the closure member 6 at this place works.Under the situation of conventional valve, closure member is maintained at apart from valve seat certain distance part, so can act on the closure member at this moment of torsion, valve is had cause the tendency of vibrating and producing noise.Therefore this improved mount scheme can be realized the improvement of operating characteristics simultaneously.By the synergy in boss 31 and aperture 29, guiding also there is further help.In assembling process and operating process, this fairly simple measure makes closure member 6 related its seal rings 21 really always be parallel to valve seat 8.
In stuffing box 26 zones, provide one in the outside of valve casing body 2 and be used for an operator, for example the stopping device of a thermostat top (not shown).Because covers for housing 3 is rotated in assembling process, this stopping device keeps its alignment that presets, thereby operator always can be fixed on the correct orientation.Assemble this valve by " from the bottom ", can easily realize this favourable effect.Fig. 2 show a radiator valve 1 ' a kind of improved form, its " internal work part " has same structure with embodiment shown in Figure 1.For simple structure is described, just critical piece has provided reference mark, i.e. closure member 6, spring 34 and inserting member 9.
In the present embodiment, valve casing body 2 ' and covers for housing 3 ' form changed.Radiator valve 1 shown in Fig. 2 ' be the form of an angle valve, that is, inlet linkage section 4 and outlet linkage section 5 embodiment no longer as shown in Figure 1 are in a straight line like that.And in contrast, inlet linkage section 4 ' and outlet linkage section 5 ' be 90 ° of angles each other to be provided with.
In order to realize this structure, in covers for housing, provide a hole 40 that internal thread 41 is arranged in simple mode.Corresponding heating liquid inlet can be connected this.Except that internal thread 21, other Placement also is feasible certainly.
Except entrance and exit linkage section 4,4 ', 5,5 ', the coniform chambers that two valve casing bodies 2,2 ' only have cylinder or diameter outwards to increase.Therefore, these apertures or hole can produce with simple tools comparatively.
Covers for housing 3 shown in Figure 2 ' also can be used under the situation of valve 1 as shown in Figure 1.This valve then is a three-way valve so.
