Description

The invention relates to a valve with a push-push actuating mechanism, which has an actuating element which forms a cap interface for a cap at its free end, wherein the valve has a base body which defines a fitting interface to a valve, wherein the actuating element is rotatable relative to the base body and guided displaceably in an actuating direction.

Such valves are known and are used for example as a diverter or as closing valves. Frequently, such valves are equipped with a switching diaphragm which can be acted upon by the working pressure of a switched liquid, the push-push actuating mechanism for switching the switching diaphragm actuates a pilot valve, which dictates the application of the switching diaphragm. The push-push actuating mechanism can in this case occupy at least two switching states, and it has also been proposed to realize more than two switching states, which are passed through one after another during actuation, for example for intermediate positions of the valve.

Since the push-push actuating mechanism does not require a rotatable actuating element, it is possible to provide a cap with a label, wherein a selected orientation of the label is maintained in the space during an actuating operation. The realization of the correct orientation, however, requires increased concentration in the assembly of the fitting, in order to avoid a wrong assembly of the items.

The invention further relates to a valve and a use of a valve on a valve.

The invention has for its object to simplify the production of a valve.

To achieve the object, the features of claim 1 are provided according to the invention. In particular, it is thus proposed according to the invention in a valve of the type described above to solve the problem that the cap interface is designed so that a cap can be connected in n orientations that the fittings interface is designed so that the body in m orientations can be used in a fitting, and that n≥m ("n is greater than or equal to m", n> = m), in particular n> m ("n is greater than m"). The advantage here is that a high number of orientations in which the cap is placed on the actuator, can be reached without this having to lead to an increased processing effort on the valve. A processing effort in a processing of the valve to form a valve mating interface, which is connectable to the fitting interface and is connected, thus low durable. The comparatively large number of orientations in which the cover cap can be placed enables easy error correction and high flexibility for covering different installation situations.

Another advantage that can be achieved with an embodiment according to the invention is an enlarged creative freedom on a front, that is, for example, a side facing away from the valve, the cap. Here, the front can be virtually any shape, for example, round, square, in free form, with a thread or other fastening devices. The invention makes it possible to achieve this with a standardized valve.

The cap interface may, for example, have a peripheral contour which is positively connected to a matching, complementarily shaped cap mating interface on a cap. Thus, a rotationally fixed attachment of the cap on the valve can be provided. The peripheral contour can be formed here, for example, as an inner contour or outer contour, which cooperates with the cap.

Alternatively or additionally, it may be provided that the fitting interface has a peripheral contour which is positively connected to a matching, complementarily shaped valve counter interface on the base body. Thus, the valve is rotatably fastened to the valve.

In one embodiment of the invention can be provided that the cap interface has an n-fold rotational symmetry. The formation of a discrete rotational symmetry at the cap interface is a simple means to define the described orientations in which the cap is connectable.

Alternatively or additionally, it may be provided that the valve interface has an m-fold rotational symmetry.

The formation of a discrete rotational symmetry at the fitting interface is a simple means to define the described orientations in which the valve can be inserted into the fitting.

In one embodiment of the invention can be provided that the cap interface has an n-sided peripheral contour. N-angular, in particular regular, circumferential contours, for example triangular, square, rectangular, pentagonal, hexagonal, octagonal, circumferential contours, are available with low production costs, for example in injection molding.

It is therefore favorable or generally, if the actuating element is made of plastic.

In an embodiment of the invention, it may be provided that n is a number divisible by four. Thus, a simple orientation of the cap at least in each of the four spatial orientations in which the valve can be operated, reachable.

In one embodiment of the invention can be provided that the fittings interface has a positioning, with which it can be used in a correspondingly shaped valve receiving a fitting in exactly one orientation. The advantage here is that for a rotationally fixed connection only a few processing steps, such as a milling of a counter-element, such as a groove for receiving the positioning, for example, a rib or spring, are required.

In one embodiment of the invention can be provided that the cap interface is designed to form a snap and / or latching connection. Thus, a simple mountable and / or detachable connection between the cap and the actuator can be produced. The solubility can be used, for example, to be able to correct a wrong orientation of the cap in the mounted state.

In one embodiment of the invention can be provided that a means for snap and / or latching connection is downstream in a Aufsteckrichtung a means for rotationally fixed guide. Thus, it is achievable that an orientation of the cap is first determined before the snap and / or latching connection firmly, in particular detachably connects the cap with the actuating element. The slip-on can be defined for example by the cap. It can be provided that at least one latching lug is formed, for example on a spring element. Thus, sufficient elasticity in the material can be provided so that the snap and / or snap connection can snap. Preferably, n latching noses are formed, or the number of latching lugs is a real divisor of n. Alternatively or additionally, it may be provided that a latching undercut is formed, for example on the cap. It is particularly favorable if the arrangement and / or configuration of the latching undercut (s) likewise have an n-fold rotational symmetry.

In one embodiment of the invention can be provided that a thread is formed on the actuating element. Thus, a releasable attachment of the cap via a screw connection can be produced. The thread may in this case be arranged, for example, upstream of the cap interface in a slip-on direction. This allows a simple attachment of the cap with a mating thread, for example on a screw or a nut. For example, the thread may be formed on a threaded bolt. This makes it possible to attach the cap on the threaded bolt and then secured with a nut. A lid may be provided to cover the nut or a screw.

In one embodiment of the invention can be provided that on the base body, a fastening element is designed for attachment to a valve, which is arranged to be movable relative to the base body. The advantage here is that the body - in contrast, for example, to a thread formed on this - does not have to be rotated from the defined orientation to secure the valve to the valve. In a structurally simple case, the fastening element may for example be a fastening nut.

To solve the problem with a fitting, the features of the sibling, directed to a fitting protection claim are provided according to the invention. In particular, according to the invention, in a fitting with a cover cap and a valve according to the invention, in particular according to one of the claims directed to a valve and / or as previously described, it is proposed that the cover cap has a cap mating interface which matches the cap interface. in particular geometrically and / or positively fitting, is formed. It is thus easily achievable that the covering cap can be mounted in n orientations, that is to say orientations with respect to an axis of rotation about which the covering cap is rotatable.

The covering cap can in this case be in one piece, in particular as already described and / or described below, or in several parts, for example with a cap base, a nut and a lid, in particular as described below.

Alternatively or additionally, according to the invention for solving the problem in a fitting with a cap and a valve according to the invention, in particular according to one of the claims directed to a valve and / or as described above, be provided that the valve has a valve mating interface to the fitting interface is designed to match. Thus, in a simple manner, a cap in different orientations rotatably mounted on a valve mountable.

In one embodiment of the invention can be provided that the valve is made of metal. The advantage here is that avoidable, relatively expensive processing steps on the metal of the valve, for example, to form a high rotational symmetry, are avoidable.

Alternatively or additionally, it can be provided in one embodiment of the invention that the cap is made of plastic. The invention thus makes use of the fact that a comparatively high rotational symmetry can be achieved easily on a plastic part, in particular in an injection-molded part. Alternatively or additionally, for example in a multi-component embodiment, the cap may be made of plastic.

In one embodiment of the invention can be provided that the valve interface is formed thread-free. The advantage here is that the main body can be used while maintaining its orientation in the valve seat.

In one embodiment of the invention it can be provided that the base body has a cylindrical basic shape at least in the area of the fitting interface. The advantage here is that the body is compatible with all discrete rotational symmetries of the fittings interface can be formed.

In one embodiment of the invention can be provided that the valve has a valve receptacle into which the main body of the valve is inserted. The valve receptacle can be milled, in particular for the formation of the already mentioned fittings counter-interface. Since the milling processing steps are particularly expensive to manufacture, a reduced rotational symmetry of the valve can be used to reduce the manufacturing effort. For example, the base body can be used in a rotationally fixed manner in the valve receptacle. The advantage here is that the orientation with which the valve is inserted into the valve, is maintained.

To achieve the object when using a valve according to the invention, the features of the sibling, directed to a use claim are provided. In particular, when using a valve according to the invention, in particular according to one of the claims directed to a valve, to a fitting according to the invention, in particular according to one of the directed to a fitting claims, it is proposed that the valve is used in a basic body orientation in the fitting and a cap is placed on the actuator in a cap orientation. Thus, an adjustment of the orientation of the cap relative to the valve can be realized in a simple manner. The opposite of the cap reduced rotational symmetry of the valve saves manufacturing costs during processing, such as turning, a valve receiving the valve, in particular the already mentioned and / or valve in detail described later.

The orientation may be defined or distinguished, for example, with respect to a label of the cap. Thus, a cap with a label in a desired orientation on the actuator can be mounted.

In one embodiment of the invention can be provided that the cap orientation is chosen so that the cap in the position of use has a desired orientation in space. Thus, a label of the cap can be easily read.

Alternatively or additionally, it can be provided in one embodiment of the invention that the base body orientation is selected so that the cover in the position of use has a desired orientation in the room. Thus, an external shape and / or contouring and / or a label and / or coloring or other marking can be easily formed for the viewer in a desired orientation.

The invention will now be described in detail with reference to an embodiment, but is not limited to this embodiment. Further exemplary embodiments result from a combination of the features of one or more subclaims with one another and / or with one or more features of the exemplary embodiment.

The 1 to 14 will be described together below.

1 shows a designated as a whole with 1 valve. The valve 1 has in known per se inside a push-push actuating mechanism 2 , which in a conventional manner by repeated pressing on an actuator 3 a switching of the valve 1 between at least two switching positions, for example, an open position and a closed position or a plurality of open positions with different opening cross-section allows.

At the free end 4 is a cap interface 5 educated. As will be discussed in greater detail, the cap interface includes 5 a number of design elements which connect to a cap 6 enable.

Here is the cap 6 on her free end 4 facing side corresponding complementary.

The valve 1 still has a basic body 7 that with my fittings interface 8th is trained. This fittings interface 8th has in more detail to be described manner design elements that allow the valve 1 in a suitably designed fitting 9 insert and attach to this.

Here, the cap is used 6 in addition, the appearance of the valve 1 to the external appearance of the fitting 9 adapt.

The actuator 3 is along an actuating direction 10 displaceable to exercise the push-push operation.

In this case, a guide known per se from push-push actuating mechanisms serves for rotationally fixed this displacement movement in relation to the actuation direction 10 respectively.

The cap interface 5 is geometrically formed so that a correspondingly formed cap 6 in four orientations, each by a rotation about one by the operating direction 10 defined axis can form 90 °, can be placed and with the actuator 3 connectable. This is achieved by using the cap interface 4 a fourfold discrete rotational symmetry about the direction of actuation 10 having.

The fittings interface 8th is here with a circumferential contour 11 equipped, which essentially, for example, apart from necessary curves - the shape of a quadrilateral or - in other embodiments - has the shape of an n-corner.

In other embodiments, other types of rotational symmetry are realized, for example, two-digit, three-fold, fünfzählige or more than fünfzählige, in particular rotational symmetry whose Symmetriegrad is described by a divisible by four number n.

In the embodiment according to the 1 to 14 is the fitting interface 8th formed with a rotational symmetry, which connects to the valve 9 allowed in a single orientation. This is done by appropriate design of a single positioning element 12 at the Circumference of the body 7 achieved by which any rotational symmetry is broken. The positioning element 12 may be formed for example as a nose or projection.

Out 3 it can be seen that the basic body 7 of the valve 1 in a valve seat 13 at the fitting 9 is set. In the valve holder 13 is a positioning recess 14 incorporated, which on the positioning 12 is tuned. Thus, the valve fits 1 only in exactly one orientation in the valve seat 13 , The positioning recess 14 in the valve holder 13 thus forms a valve counter interface 40 ,

By forming the described symmetry at the cap interface 5 can thus be achieved that the cap 6 can be positioned in a variety of orientations without the valve seat 13 must deviate significantly from a round inner contour. The valve holder 13 which is usually in a metallic fitting 9 is incorporated, can therefore be produced with simple manufacturing processes. Post-processing is required only to a small extent, for example, for introducing the Positionierausnehmung 14 ,

The cap interface 5 has a means for forming a snap and / or latching connection 15 on. These are used to attach the cap 6 on the free end 4 ,

In 5 It can be seen that the means for forming a snap and / or locking connection 15 in a slip-on direction 16 the beginning of the circumferential contour 11 , by which a means for rotationally fixed leadership 17 the cap 6 is formed, arranged downstream. The leadership results from the fact that the circumferential contour 11 in Aufsteckrichtung 16 is continued, so that parallel to Aufsteckrichtung 16 form running surfaces. The cap counter interface 21 has corresponding surfaces that interact with these surfaces.

This ensures that the cap 6 first with the means for non-rotatable leadership 17 comes into contact. Further pushing on the cap 6 on the actuator 3 causes a latching of the cap 6 on the free end 4 ,

In 6 to 9 it can be seen that the cap has a recess 18 having. The recess 18 is on the circumferential contour 11 the free end 4 adjusted so that the cap 6 on the free end 4 rotatably, but in Aufsteckrichtung 16 slidably guided.

On the cap 6 are latching undercuts 19 trained, with locking springs 20 the means for forming a snap and / or locking connection 15 lock. The detent springs 20 are each made of a spring element 38 and a catch 39 composed or have each on.

The recess 18 and the locking undercuts 19 thus form a cap-mating interface 21 leading to the cap interface 5 fits. The symmetry of the caps counter interface 21 can be identical to that of the cap interface 5 or be compatible with this (for example, zweizählig) trained.

At the base body 7 is a section with a cylindrical basic shape 22 as insertion section 23 formed on the the positioning 12 is attached. This insertion section 23 fits in the valve holder 14 , Before this insertion section 23 is a mounting section 24 trained, the retaining lugs 25 on a housing part 26 wearing.

On the housing part 26 is a mounting element for mounting 27 , here a fixing nut 28 , set, that of the retaining lugs 25 held captive in their position.

The fastener 27 is with a mating thread 29 in a thread 30 the valve seat 13 screwed to the valve 1 to fix. Thus, the valve must 1 even not be turned, and the orientation of an attached cap 6 Remains in relation to the fitting 9 receive. On the fastener 27 is a tool attack on the circumference 31 , For example, an external hex, designed to hold the valve tight 1 to reach.

The valve 1 closes, as in 3 it can be seen, a connection between an inlet 32 and an outlet 34 or releases them. A seal 33 between the inlet 32 and the outlet 34 prevents leakage currents when the valve is closed 1 ,

In 4 are guide elements 35 a known push-push actuating mechanism 2 shown. These guide elements 35 cause a rotationally fixed, in the direction of actuation 10 sliding guide of the actuating element 3 and thus a latched with this cap 6 ,

It is thus possible, as in 14 shown, a mark 36 on the cap 6 permanently in four different orientations with respect to the fitting 9 - In other embodiments in n different orientations - align. Thus, the mark 36 independently from the installation position of the valve 9 always be aligned so that a user can perceive them correctly.

The 15 and 16 show a further embodiment of the invention. Structurally and / or functionally identical or identical components and functional units are designated by the same reference numerals and are not described separately again. The remarks to the 1 to 14 therefore apply to the 15 and 16 corresponding.

The embodiment of the 15 and 16 differs from the previous embodiment in that the cap mating interface 21 is also formed vierzählig, while this was twofold in the previous embodiment. This achieves a firmer hold of the cap 6 on the free end 4 ,

The embodiment of the 15 and 16 differs from the previous embodiment also in that on the cap 6 a survey 37 is formed, which in a recess 18 at the free end 4 of the actuating element 3 is used. Here is the perimeter contour 11 through which the rotationally fixed connection between the cap 6 and the actuator 3 is manufactured, formed as an inner contour, while in the 1 to 14 is formed as an outer contour.

The 17 to 19 show a further embodiment of the invention. Structurally and / or functionally identical or identical components and functional units are designated by the same reference numerals and are not described separately again. The remarks to the 1 to 16 therefore apply to the 17 to 19 corresponding.

The embodiment of the 17 to 19 differs from the previous embodiment in that no latching connection between the actuating element 3 and the cap 6 is trained.

Rather, in this variant on the actuating element 3 a thread 41 educated. This thread 41 is on a threaded bolt 42 arranged, and can with a mating thread 43 on a holding nut 44 be screwed.

Because of the threaded bolt 42 the cap interface 5 upstream, the threaded bolt can 42 by a cap plot 45 put through, with the retaining nut 42 fixed and behind a lid 46 be hidden.

At least a pen 47 - here are two pens 47 - on the lid 46 and at least one - here two - matching pen holder 48 at the cap plot 45 form an anti-twist device. This rotation is in other embodiments in other ways, for example by designing appropriate contours and / or by a positive, non-positive and / or cohesive connection between the lid 46 and cap plot 45 , educated.

In another embodiment, not shown, the actuating element is designed in several parts and includes the in 17 to 19 represented parts 3 and 45 , The cap is through the part 46 formed, and the cap interface 5 is through the pen shots 48 realized. With the two pen shots 48 is a rotational symmetry of 180 °, ie n = 2, prepared. Higher values for n are due to a larger number (n) of evenly distributed pen shots 48 reached. The pencils 47 define the cap counter interface 21 , The contours of the details 5 and 21 can be designed in this case so that a connection in only one orientation is possible. Incidentally, the embodiment as in the 17 to 19 be designed.

With a sanitary valve 1 with a push-push operating mechanism 2 It is thus proposed to use a cap interface 5 between a cap 6 and an actuator 3 with a higher rotational symmetry than a valve interface 8th between the valve 1 and a fitting 9 train.
