Liquid distribution valve with a rotatable in a valve canister arranged wing closing member

The invention relates to a liquid distribution valve with a vane closing member which is rotatably arranged in a valve chamber and is designed in such a way that in at least two end positions the valve chamber is tightly closed in two or more separate fluid divides rooms, and that with a plurality of fluid connections to the valve chamber, which are optionally in the end positions of the wing closure member can be connected to one another via the liquid spaces, is provided.

The function required of a liquid distribution valve is to provide connections between. Liquid lines selectively to produce and the separation of the fluid lines thus formed from other communication paths to undertake. If z. B. the requirement is that one Fluid line «for example in a system two inlet ducts and two outlet ducts, requires what is required for the necessary control Valve unit often has a very complex structure and requires high costs in manufacture, installation, of cleaning and preservation.

An earlier proposal for a liquid distribution valve using a wing shutter resulted an extremely complex construction, which is not accepted by the relevant technical circles became·

The object of the invention is to create a liquid distribution valve of the type mentioned at the beginning, whose construction is clear and simple, and only minimal for assembly, cleaning and maintenance Requires expenses. This object is achieved according to the invention in that the valve chamber in large and whole is hollow spherical, and that circumferential seals are provided on its wall, which with the The outer edge of the sash closing element interact to form separate fluid spaces

4439/78

In a preferred embodiment of the liquid distribution valve according to the invention, its valve chamber is composed of spherical segments which are firmly connected to one another along their adjacent hard edges with the insertion of sealing rings which form the circumferential seals, as a result of this type of construction of spherical segments Tiird it _s allows the valve at any time to break down and make it accessible to the interior of the valve chamber for the purpose of cleaning and overhaul ,,

To prevent over-compression, the circumferential seals are preferably connected with metallic spacers which do not allow a maximum compression to be exceeded _{or the like}

In a further advantageous embodiment, the valve blades are made up of two disks with an emptying space that is sensitive between them Valve adjustment towards = penetrates _s from supply ₀ _

Suitably, this discharge space looks to the interior of the formed as a hollow shaft on which the valve "are mounted wings ₉ in fluid communication, so that the hollow shaft at the same time the function of a liquid leak" derivative met _o

To get in too much may be more costly To prevent liquid from leaking into the emptying space, a closure device can be provided in a further embodiment which closes automatically when changing from one valve position to the other.

The invention is explained in more detail below with reference to the accompanying drawings. In these show:

Figure 1 shows an embodiment of the inventive Liquid distribution valve in perspective view, partly broken

FIG. 2 shows the valve according to FIG. 1 in the horizontal plane;

Figure 3 is another or different embodiment. foric of the invention according to en valve in a similar manner Representation as in Figure 2. "

The valve shown in Figures 1 and 2 on the one ordered from Ventilliamaies · of hollow spherical! ^1- shaped shape "consisting of four housing segments II which (H) each have flanges 12 at their end edges", by means of which they are firmly connected to the respectively adjacent element II . Semicircular seals Ij are embedded between the flanges 12. Spacer pieces 14 are arranged behind the seals 13 and are intended to prevent any over-compression of the seals. The spacers 14 can be connected in one piece to one of the flanges 12, or they can also be designed as independent elements.

Three of the housing segments 11 are equipped with fluid connections in the form of pipe sockets 15a, 15b9, 15b ο For the purpose of making production easier, the pipe sockets I5 are arranged in the lower or upper part of the housing segments II in such a way that that the valve housing can empty itself o The housing <= S @ gmente 11 with the pipe socket I5 are designed exactly the same "so that they can optionally be exchanged and also reversed in order to provide the pipe socket optionally in the upper or lower part o The housing = segments 11 are connected along two diametrical planes, and the diameter of these planes intersects the central axis of a shaft 16 ₉ which carries wings I7 _o The shaft 16 is designed as a hollow shaft at least in the lower part of its length. It can also be square or hexagonal over part of its length Have a cross-section for attaching a handle

On the upper part of the housing a plate 13 is arranged which has a bearing with a seal for the Shaft 16 carries ο a <= not shown in the drawing = a similar plate is provided on the lower part of the housing »

The plate 18 is preferably integrally formed with the Ab = stood pieces Ik or firmly connected thereto _s so that the entire assembly of shaft, wings and seals can be afogenommen from the "valve chamber for cleaning and maintenance _o a handle for the X'Jell © 16 is ₈ as shown in the drawing, on a console 21 gshalterto

It can be seen that the wings 17 each from one Pair of spaced apart circular disks are formed, which are arranged so that they form a drainage channel for any leakage fluid, which has penetrated into the space between the plates. Each space is in fluid communication with the interior the hollow shaft which, as a derivative for any in the Liquids that have penetrated into the space - or possibly gases - are used »

As can be clearly seen in Figure 2, the valve of Figures 1 and 2 has two wings 1? Which can be brought into operative connection alternatively with opposing pairs of seals 13 so as to make the connection between the inlet port 15a and the outlet 15b or either the Auslaöfcutzen 15c, while the respective third pipe connection is shut down. It deserves to be mentioned, that the intermediate space between the vanes to the inlet nozzle 15a comes into communication during the change of the valve position j in order to avoid too great a loss of just ± m operation may befindlichen- costly fluid - be it in the process operation or cleaning - A preferably automatically acting closure is provided for the emptying channel, which is effective when changing from one position to the other. Such a closure can for example be actuated by a star wheel driven by the shaft 16.

The invention is not limited to the three-way valve of Figures 1 and 2o. For example, by a fourth connection seat the valve according to FIG to a shuttle valve. Another embodiment is shown in Figure 3, in which four fluid connections are provided in connection with a three-way valve, so that two connections can be brought into connection with each other while the others are closed are β

As can be readily seen, the seals must I3 in Figures I ₅ 2, 3 by no means - as shown - be arranged at an angle of 9O each other "It is also well possible to use another divisor of 36Ο, z" B ₀ 120 or 60 to use This would require that the valve housing consists of three or six segments housing is made ₀ another possible embodiment would be the use of two valve wings in a V shape.

Various other modifications are possible within the scope of the invention.
