Description

The present invention relates to a method for producing an outlet valve and an outlet valve. Such an outlet valve is used in particular to dispense a liquid, in particular water, as needed at a washbasin or sink.

The outlet valve can have a valve housing with an inlet and an outlet for the liquid. The inlet and the outlet are connected to one another via a liquid channel so that the liquid can flow from the inlet to the outlet. Since the water is in contact with the valve housing, valve housings must be made of a material that is suitable for drinking water and is not susceptible to corrosion, such as brass.

In order to be able to use more cost-effective materials for valve housings, outlet valves are already known in which the liquid channels in the valve housing are coated with plastic. In addition, the liquid channels can be at least partially formed by a plastic water guide, which prevents the liquid from coming into contact with the valve housing. Correspondingly adapted plastic water guides are required for different sizes or lengths of the valve housings, which leads to a large variety of variants and high manufacturing costs.

The object of the invention is therefore to at least partially solve the problems described with reference to the prior art and in particular to provide a method for producing an outlet valve by which the variety of variants of the plastic water pipes can be reduced. In addition, an outlet valve should also be specified, with which the variety of plastic water pipes can be reduced.

These tasks are solved with a method and an outlet valve according to the features of the independent patent claims. Further advantageous embodiments of the invention are specified in the dependently formulated patent claims. It should be noted that the features listed individually in the dependent patent claims can be combined with one another in any technologically sensible manner and define further embodiments of the invention. In addition, the features specified in the patent claims are specified and explained in more detail in the description, with further preferred embodiments of the invention being presented.

1. a) Bereitstellen eines Ventilgehäuses mit einem Zulauf für eine Flüssigkeit und einem Ablauf für die Flüssigkeit, wobei der Zulauf und der Ablauf über zumindest einen Flüssigkeitskanal verbunden sind;
2. b) Anordnen einer ersten Kunststoffwasserführung in dem Ventilgehäuse, wobei die erste Kunststoffwasserführung eine erste Länge aufweist und den zumindest einen Flüssigkeitskanal zumindest teilweise bildet, sodass ein Kontakt der Flüssigkeit mit dem Ventilgehäuse verhindert wird; und
3. c) Verlängern der ersten Kunststoffwasserführung mit zumindest einer zweiten Kunststoffwasserführung, wenn die erste Länge der ersten Kunststoffwasserführung zum Verhindern des Kontakts der Flüssigkeit mit dem Ventilgehäuse nicht ausreicht.

A method for producing an outlet valve, which has at least the following steps, contributes to this:

1. a) providing a valve housing with an inlet for a liquid and an outlet for the liquid, the inlet and the outlet being connected via at least one liquid channel;
2. b) arranging a first plastic water guide in the valve housing, wherein the first plastic water guide has a first length and at least partially forms the at least one liquid channel, so that contact of the liquid with the valve housing is prevented; and
3. c) extending the first plastic water guide with at least one second plastic water guide if the first length of the first plastic water guide is not sufficient to prevent contact of the liquid with the valve housing.

The outlet valve is used in particular to dispense a liquid (as needed), for example (drinking) water, to a sink, sink and/or another point where liquid is required. The outlet valve can be designed in the manner of a sanitary fitting and/or intended for a drinking water installation in a building. The outlet valve can be designed in the manner of a shut-off valve or can include a shut-off valve. In particular, a volume flow of the liquid dispensed with the outlet valve can be controlled via the shut-off valve. For example, the liquid can be dispensed through the outlet valve with a volume flow of up to 0.5 l/s [liters per second]. In particular, the outlet valve does not have a mixing valve for mixing cold water and hot water to form mixed water.

In step a), a valve housing of the outlet valve is provided. The valve housing can be at least partially tubular, designed in the manner of a tube and/or in the manner of a base body. The valve housing can be attachable to a support, for example a wall or building wall. In particular, the valve housing can be rigidly fastened to the carrier and/or to the carrier at its first longitudinal end. The valve housing may have a decorative external surface.

1. a) 3,8 - 4,2 % AI, 0,035 - 0,06 % Mg, Rest (insbesondere) Zn (Zamak-Legierung ZL0400),
2. b) 3,8 - 4,2 % Al, 0,7 - 1,1 % Cu, 0,035 - 0,06 % Mg, Rest (insbesondere) Zn (Zamak-Legierung ZL0410) oder
3. c) 3,8 - 4,2 % Al, 2,7 - 3,3 % Cu, 0,035 - 0,06 % Mg, Rest (insbesondere) Zn (Zamak-Legierung ZL0430).

The valve housing can consist at least partially or completely of a zinc alloy. The zinc alloy is in particular a metal alloy whose main component or base metal is zinc (Zn). This can mean in particular that zinc compared to the other alloy components of the zinc alloy has the largest mass fraction. The zinc alloy can contain zinc with a mass fraction of more than 80%. In particular, the zinc alloy can contain zinc with a mass fraction of more than 90% or 95%. The zinc alloy or zinc has a different crystal structure compared to copper or a copper alloy, such as brass, namely hexagonal instead of face-centered cubic. The zinc alloy can in particular be a so-called Zamak alloy. The zinc alloy can include, for example, at least aluminum (Al), magnesium (Mg) and/or copper (Cu) as further alloy components. In particular, the zinc alloy can comprise the following mass proportions of alloy components:

1. a) 3.8 - 4.2% AI, 0.035 - 0.06% Mg, balance (in particular) Zn (Zamak alloy ZL0400),
2. b) 3.8 - 4.2% Al, 0.7 - 1.1% Cu, 0.035 - 0.06% Mg, the balance (in particular) Zn (Zamak alloy ZL0410) or
3. c) 3.8 - 4.2% Al, 2.7 - 3.3% Cu, 0.035 - 0.06% Mg, balance (in particular) Zn (Zamak alloy ZL0430).

Before step a), the valve housing can be manufactured using a zinc die-casting process. In the zinc die-casting process, in particular a liquid melt of the zinc alloy is pressed under pressure into a die-casting mold. After the melt has solidified, the valve housing can be removed from the mold and, if necessary, mechanically processed. The valve housing is therefore in particular a zinc die-cast part.

The valve housing has an inlet for the liquid and an outlet for the liquid. The liquid can be fed to the valve housing in particular via the inlet. The inlet can be connectable to a supply line, which can be at least partially designed in the manner of a pipeline and/or hose line. The outlet valve or the valve housing can be connected in particular to a liquid source, for example in the manner of a (public) water supply network, via the supply line. The inlet can be formed at the first longitudinal end of the valve housing. The liquid can be dispensed via the outlet through the outlet valve or the valve housing, for example to the sink, sink, an area surrounding the outlet valve, a pipeline and/or hose line. The process can be designed in the manner of an opening, have a mousseur and/or have a jet former. The drain can be formed at a second longitudinal end of the valve housing. The valve housing can have a straight section which extends, for example, from the first longitudinal end or the inlet. After the outlet valve or the valve housing has been attached to the carrier, the straight section can in particular (essentially) run horizontally. The straight section can extend to a bend in the valve housing. The bend can, for example, have an angle of 30° to 90°. The bend can extend to the second longitudinal end of the valve housing and/or to the drain. Alternatively, the bend can be followed by a further straight section of the valve housing, which extends from the bend to the second longitudinal end and/or the drain. The inlet and the outlet are connected via at least one liquid channel. The at least one liquid channel extends in particular through the valve housing.

In a step b), a first plastic water guide is arranged in the valve housing. The first plastic water guide consists at least partially of plastic and/or is designed in the manner of a plastic injection molded part. The first plastic water guide is in particular not designed in the manner of a (flexible) hose. The first plastic water guide can be at least partially tubular and/or have an outer diameter that (essentially) corresponds to an inner diameter of the valve housing. The first plastic water guide can have a first, in particular straight, longitudinal axis. The first longitudinal axis of the first plastic water guide can run coaxially or parallel to a longitudinal axis of the valve housing. The first plastic water guide can have a first inlet for the liquid and/or a first outlet for the liquid. The first inlet and the first outlet may be formed on opposite sides of the first plastic water guide. The first inlet and the first outlet can be formed coaxially, parallel and/or with an offset from one another. The first plastic water guide has a first length, which can be measured, for example, along the first longitudinal axis and/or from the first inlet to the first outlet. The first plastic water guide at least partially forms the at least one liquid channel, so that contact of the liquid with the valve housing is at least partially prevented by the first plastic water guide. This can mean, for example, that the at least one liquid channel extends at least partially through the first plastic water guide and/or the first plastic water guide at least partially delimits the at least one liquid channel.

In a step c), the first plastic water guide is extended with at least a second plastic water guide if the first Length of the first plastic water guide is not sufficient to prevent the liquid from coming into contact with the valve housing. This can be the case in particular if a total length of the valve housing and/or a first housing length of the valve housing extending from the first longitudinal end of the valve housing to a center of a valve device of the outlet valve is too large. In this case, an inner surface of the valve body would be exposed so that the liquid can contact the valve body.

The second plastic water guide consists at least partially of plastic and/or is designed in the manner of a plastic injection molded part. The second plastic water guide is in particular not designed in the manner of a (flexible) hose. The second plastic water guide can be at least partially or completely tubular and/or have an outer diameter that (essentially) corresponds to the inner diameter of the valve housing. The second plastic water guide can have a second, in particular straight, longitudinal axis. The second longitudinal axis of the second plastic water guide can run coaxially or parallel to the longitudinal axis of the valve housing and/or to the first longitudinal axis of the first plastic water guide. The second plastic water guide may have a second inlet for the liquid and/or a second outlet for the liquid. The second inlet and the second outlet may be formed on opposite sides of the second plastic water guide. The second inlet and the second outlet can be formed coaxially, parallel and/or with an offset from one another. The second plastic water guide has a second length, which can be measured, for example, along the second longitudinal axis and/or from the second inlet to the second outlet. The second plastic water guide at least partially forms the at least one liquid channel, so that contact of the liquid with the valve housing is at least partially prevented by the second plastic water guide. This can mean, for example, that the at least one liquid channel extends at least partially through the second plastic water guide and/or the second plastic water guide at least partially delimits the at least one liquid channel.

The first plastic water guide and the second plastic water guide can be connected to one another (preferably immediately or directly), in particular without liquid being able to escape through a connection point between the first plastic water guide and the second plastic water guide. The connection can be made via a first plug connection. The first plug connection can have a first seal, for example in the manner of an O-ring. The connection of the first plastic water guide and the second plastic water guide can take place before step b) and/or outside the valve housing. The first plastic water guide and the second plastic water guide can then be arranged together in the valve housing. Alternatively, the second plastic water guide can be arranged in the valve housing after the first plastic water guide. The first plastic water guide can be extended in a corresponding manner with a plurality of second plastic water guides. The second plastic water guides can each have the same second length or different second lengths. The first plastic water guide and the at least one second plastic water guide or the first plastic water guide and the second plastic water guides can be assembled, in particular in the manner of a modular system. Extending the first plastic water guide serves to adapt a total length of the plastic water guides to the valve housing, the total length of the valve housing and/or the first housing length of the valve housing. This enables the use of the first plastic water guide or identical first plastic water guides in valve housings of different sizes, so that no adapted variants of the first plastic water guide have to be produced for valve housings of different sizes. This allows the variety of variants of the first plastic water pipes to be reduced. Since the at least one second plastic water guide can be designed with less complexity than the first plastic water guide, the tools required for the plastic injection molding of the at least one second plastic water guide can be manufactured more cost-effectively, which reduces the cost of producing the outlet valve.

The first plastic water guide can have a valve seat for a valve body. The valve seat can, for example, be designed in the manner of a, in particular annular, sealing surface. The valve body can be part of a valve device. The valve device can comprise an actuating element, for example in the manner of an actuating handle. The actuating element can be rotatable about an axis of rotation by a user of the outlet valve to open and/or close the outlet valve. When the outlet valve is opened, the valve body can be lifted from the valve seat by the valve device and/or pressed against the valve seat when the outlet valve is closed. The valve housing can have a valve receptacle in which the valve device can be fastened. The attachment of the valves Direction in the valve receptacle can be done, for example, by a screw connection.

The first length (of the first plastic water guide) can be 50 mm [millimeters] to 200 mm.

The second plastic water pipe can connect the first plastic water pipe to a connecting nipple of the inlet. In particular, the supply line for the liquid can be connected to the connection nipple. The connection nipple can be fastened in the inlet or the valve housing, for example using a screw connection. The connection nipple and the second plastic water pipe can be connected to one another via a second plug connection. The second plug connection can include a second seal, for example in the manner of an O-ring. The connection nipple can be at least partially tubular. The liquid channel can extend through the connection nipple.

The first plastic water guide and the at least one second plastic water guide can be connected to one another via a first plug connection.

The second plastic water guide can have a second length of 5 mm to 500 mm. The second plastic water guide can have a second length of preferably 5 mm to 100 mm.

A third plastic water guide can be arranged in the valve housing, which connects the first plastic water guide to the drain. The third plastic water guide consists at least partially of plastic and/or is designed in the manner of a plastic injection molded part. The third plastic water guide is in particular not designed in the manner of a (flexible) hose. The third plastic water guide can be at least partially or completely tubular and/or have an outer diameter that is smaller than the inner diameter of the valve housing. The third plastic water guide may have a third inlet for the liquid and/or a third outlet for the liquid. The third inlet and the third outlet may be formed on opposite sides of the third plastic water guide. The third plastic water guide can be at least partially curved and/or run through the bend of the valve housing. The third plastic water guide at least partially forms the at least one liquid channel, so that contact of the liquid with the valve housing is at least partially prevented by the third plastic water guide. This can mean, for example, that the at least one liquid channel extends at least partially through the third plastic water guide and/or the third plastic water guide at least partially delimits the at least one liquid channel.

The third plastic water guide can be arranged at least partially in the valve housing using at least one guide of the valve housing. The at least one guide can be designed in the manner of a groove and/or extend from the outlet into the valve housing or in the direction of the first plastic water guide. The third plastic water guide can have at least one guide wing which slides in the at least one guide when the third plastic water guide is inserted into the valve housing and/or centres the third plastic water guide in the valve housing. This makes it easier to produce a third plug connection between the first plastic water guide and the third plastic water guide.

The method can be used to produce a plurality of outlet valves whose valve housings have different overall lengths, with a first plastic water guide having the same first length being arranged in all valve housings of the outlet valves. For this purpose, in step a), a plurality of valve housings with different overall lengths, first housing lengths and/or second housing lengths can be provided. The second housing length can extend from the axis of rotation of the valve unit to a center of the drain and/or the mousseur. The first housing length and/or second housing length can in particular be dimensioned parallel to the longitudinal axis of the valve housing, parallel to the inlet, orthogonal to the axis of rotation of the valve device, parallel to the first longitudinal axis of the first plastic water guide and/or parallel to the second longitudinal axis of the second plastic water guide . The plurality of valve housings can at least partially be provided in parallel or one after the other. In step b), in particular identical first plastic water guides can be arranged in the plurality of valve housings.

Following a further aspect, an outlet valve is also proposed which has at least the following:

• - a valve housing with an inlet for a liquid and an outlet for the liquid, the inlet and the outlet being connected via at least one liquid channel;

The plastic water guides can be in the form of a set for a type of outlet valve.

The outlet valve is manufactured in particular using the method proposed here.

For further details on the outlet valve, reference is made in full to the explanations of the outlet valve in the process description.

• 2: die erste Variante des Auslaufventils in einer Schnittdarstellung; und
• 3: eine zweite Variante des Auslaufventils in einem Längsschnitt.

The invention and the technical environment are explained in more detail below using the figures. It should be noted that the figures show a particularly preferred embodiment variant of the invention, but this is not limited to this. The same components in the figures are given the same reference numbers. It shows schematically:

• 1 : a first variant of an outlet valve in a longitudinal section;
• 2 : the first variant of the outlet valve in a sectional view; and
• 3 : a second variant of the outlet valve in a longitudinal section.

The 1 shows a first variant of an outlet valve 1 in a longitudinal section. When producing the outlet valve 1, a valve housing 2 was provided in step a). The valve housing 2 extends in a tubular shape from an inlet 3 to an outlet 4. At a first longitudinal end 17 of the valve housing 2, the valve housing 2 or the inlet 3 has a contact surface 19 for a carrier, not shown here. The support can be, for example, a wall of a building. The outlet valve 1 or the valve housing 2 can in particular be rigidly attached to the carrier. The inlet 3 and the outlet 4 are connected via a liquid channel 5 extending through the valve housing 2, so that a liquid can flow from the inlet 3 to the outlet 4. The process 4 is formed on a second longitudinal end 18 of the valve housing 2, which is opposite the first longitudinal end 17. A mousseur 20 is arranged at the outlet 4, via which the liquid can be delivered to an environment 21 of the outlet valve 1. The valve housing 2 has a straight course from the inlet 3 to a bend 16. The bend 16 can, for example, have an angle of 30° to 90°. The valve housing 2 extends from the bend 16 to the drain 4.

In a step b), a first plastic water guide 6 was inserted into the valve housing 2 through the inlet 3. The first plastic water guide 6 is tubular and extends along its first longitudinal axis 24 with a first length 7 from a first inlet 22 to a first outlet 23. The first inlet 22 and the first outlet 23 are on opposite sides of the first plastic water guide 6 and formed parallel to each other. The liquid channel 5 extends through the first plastic water guide 6, so that the liquid cannot contact the valve housing 2 in the area of the first plastic water guide 6. The first plastic water guide 6 has a valve seat 9 for a valve body 10 of a valve device 25. The valve device 25 is designed in the manner of a valve upper part and has an actuating element 26. The actuating element 26 can be rotated about an axis of rotation 27 by a user of the outlet valve 1 for opening and/or closing the outlet valve 1. When the outlet valve 1 is opened, the valve body 10 is lifted from the valve seat 9 by the valve device 25 and is pressed against the valve seat 9 by the valve device 25 when the outlet valve 1 is closed. The valve device 25 is fastened in a valve receptacle 32 of the valve housing 2.

The valve housing 2 has a first housing length 15 from the inlet 3 or the first longitudinal end 17 of the valve housing 2 to the axis of rotation 27 of the actuating element 26 or a center of the valve device 25. The valve housing 2 has a second housing length 30 from the axis of rotation 27 to a center 29 of the mousseur 20. The first housing length 15 and/or the second housing length 30 are dimensioned in particular parallel to a housing longitudinal axis 28 of the valve housing 2, parallel to the inlet 3, orthogonal to the rotation axis 27 and/or parallel to the first longitudinal axis 24 of the first plastic water guide 6. The first Housing length 15 and the second housing length 30 result in a total length 50 of the valve housing 2. The valve housing 2 has a housing depth 31 from the housing longitudinal axis 28 to the center 29 of the mousseur 20. The housing depth 31 is measured in particular orthogonally to the longitudinal axis of the housing 28, orthogonally to the inlet 3, parallel to the axis of rotation 27, orthogonally to the first housing length 15 and/or orthogonally to the second housing length 30.

Since the first housing length 15 of the valve housing 2 is so large that the first plastic water guide 6 does not extend to the inlet 3 or a connection nipple 11 of the inlet 3, the first plastic water guide 6 was extended in a step c) with a second plastic water guide 8. For this purpose, the second plastic water guide 8 was inserted through the inlet 3 into the valve housing 2 so that the first plastic water guide 6 and the second plastic water guide 8 are connected to one another via a first plug connection 12. The second plastic water guide 8 is tubular and extends along its second longitudinal axis 33 with a second length 34 from a second inlet 35 to a second outlet 36. The second inlet 35 and the second outlet 36 are on opposite sides of the second plastic water guide 8 and parallel to one another. The liquid channel 5 extends through the second plastic water guide 8 so that the liquid cannot contact the valve housing 2 in the area of the second plastic water guide 8. A first seal 37 in the form of an O-ring is arranged in the area of the first plug connection 12. The first plastic water guide 6 and the second plastic water guide 8 each have an outer diameter 46 which (substantially) corresponds to an inner diameter 47 of the valve housing 2.

After arranging the second plastic water guide 8 in the valve housing 2, the connecting nipple 11 was fastened in the inlet 3 or the valve housing 2, so that the connecting nipple 11 and the second plastic water guide 8 are connected to one another via a second plug connection 40. In the area of the second plug connection 40, a second seal 38 is arranged in the form of an O-ring. A supply line for the liquid, not shown here, can be connected to the connection nipple 11. The connection nipple 11 is tubular, so that the liquid channel 5 extends through the connection nipple 11.

Through the process 4, a third plastic water guide 13 was inserted into the valve housing 2, so that the first plastic water guide 6 and the third plastic water guide 13 are connected to one another via a third plug connection 41. The third plastic water guide 13 was arranged in the valve housing 2 in particular before the first plastic water guide 6. In the area of the third plug connection 41, a third seal 39 is arranged in the form of an O-ring. The third plastic water guide 13 is curved and extends through the bend 16 of the valve housing 2 from the first plastic water guide 6 to the outlet 4. As a result, the liquid can be guided from the inlet 3 to the outlet 4 without contact with the valve housing 2.

The 2 shows the first variant of the valve housing 2 in a sectional view along the in the 1 shown section line II-II. The valve housing 2 has a first guide 14 and a second guide 43 on an inner wall 42 in the area of the bend 16, which lie opposite one another. The guides 14, 43 are each designed in the manner of a groove and extend from the drain 4 into the valve housing 2 or in the direction of the 1 shown first plastic water guide 6. The third plastic water guide 13 has a first guide wing 44 and a second guide wing 45, which slide in the guides 14, 43 when the third plastic water guide 13 is inserted into the valve housing 2 and center the third plastic water guide 13 in the valve housing 2. This makes the production in the 1 shown third plug connection 41 between the first plastic water guide 6 and the third plastic water guide 13 makes it easier when arranging the first plastic water guide 6 in the valve housing 2.

The 3 shows a second variant of the outlet valve 1 in a longitudinal section. The second variant of the outlet valve 1 was manufactured using the same process as that in the 1 and 2 shown first variant of the outlet valve 1. In step a), compared to the first variant of the outlet valve 1, a valve housing 2 with a shorter first housing length 15 was provided. After arranging the first plastic water guide 6 in the valve housing 2 in step b), the connecting nipple 11 could be fastened in the inlet 3 or the valve housing 2, so that the connecting nipple 11 and the first plastic water guide 6 are (directly) connected to one another via a fourth plug connection 48 are. In the area of the fourth plug connection 48, a fourth seal 49 is arranged in the form of an O-ring. The first plastic water guide 6 did not have to be extended with a second plastic water guide 8 in step c) in order to prevent the liquid from coming into contact with the valve housing 2.

All components of the second variant of the outlet valve 1 are designed identically to the components of the first variant of the outlet valve 1, with the exception of the valve housing 2. The second variant of the outlet valve 1 differs from the first variant of the outlet valve 1 only in that the first housing length 15 of the valve housing 2 is smaller.

The present invention can reduce the number of variants of plastic water pipes.
