A device for cleaning and discharging a conduit, in particular a conduit, for dispensing beverages in taps

Technical field

BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a device for cleaning and discharging fluid lines, in particular beverage lines in taps, with a slide valve or a rotary slide valve, in which the valve valve is movable in a recess of the valve body such that at least one transverse bore In the valve-valve slide, a beverage flow can be connected to the connection sleeve, and a cylindrical reservoir of flexible, spherical-cleaning bodies as well as a feeder sleeve can be connected.

Background Art

The invention is based on a cleaning device as described in DE-CS 35 04 636. In this cleaning device, a connection sleeve is provided in the top wall and in the bottom wall of the valve body for guiding the beverages leading to the tap and the connecting sleeve for conveying beverages to the drum. The bottom of the valve body is mounted on one threaded connection to the water inlet and outlet. The ball-shaped, elastic cleaning container is mounted on the top of the valve body. The gate valve is constructed in two parts and has a switching body with its longitudinal axis &amp; which is provided with a central bore extending up to the end ball. With the aforementioned known device, the beverage line leading to the barrel and the tap tap should alternately be cleaned while the operation or tapping does not cause any discomfort. The formerly known device is constructed in a rather complicated manner and can only be actuated in situ by means of a sliding gear lever and a rotary gear lever. In addition, the purification of the beverage line leading to the drying and tapping tap can only be carried out in an alternate manner. The present invention has as its primary object the simplification of the previously known cleaning device with respect to its construction and operation between tapping and cleaning.

SUMMARY OF THE INVENTION

According to the invention, this object is achieved by providing a cylindrical container of flexible, spherical cleaning bodies and connection sleeves, directly to the upper side of the slide valve, which is actuated by an operable drive device, over its respective through bore, leading to a spring. the beverage connection of the cleaning water supply and the beverage supply connection have the same distance from the bottom of the valve body as the two through bores in the slide valve, so that in the end position of the valve in the operating state the two through bores in both the lower part of the valve body and the two connecting nozzles and during cleaning or emptying, the connection of the supply lines is closed and the beverage line leading to the tap is connected to the threaded connection for the supply of cleaning water; at the top a threaded connection portion -3- for supplying cleaning water to accommodate a spherical, flexible cleaning body that falls into this space from the tubular container during operation and is extruded through the water column through the bins to the bar during cleaning.

The cleaning device according to the invention achieves a substantial advantage that, compared to the previously known device described in DE-OS 35 04 636, the cleaning and emptying of the beverage leading to the beverage can be carried out by means of a substantially simpler valve and rotary slide valve. By means of a particularly simple design, the device according to the invention can also be used directly in beverage containers, for example a beer barrel, so that a special supply can be omitted between the beer barrel and the apparatus of the invention.

A further advantage of the device according to the invention is that the cleaning of the beverage line to the tap can be carried out by the loss of beverages, since the beverage which is being crushed at the start of the cleaning can still be used completely until the cleaning body appears.

With the particular arrangement of the cleaning body magazine directly on the valve valve slide or the rotary valve valve, there is a problem with the sealing of the moving parts only between the connections in the lower part of the valve body and the slide. This solution is therefore particularly advantageous because the slider or the rotary slide is a direct connection of the patches leading to the tap. Of course, this resilient guide can also only consist of a part of the overall guide, whereby the flexibility of this guide must only be taken into account in relation to the slide valve slide valve.

In accordance with claim 3, the drive means for releasing the valve slide is made of a pressure piston which is optionally remotely controlled and which is sprayed

1 with carbon dioxide from a pressurized bottle, which is used, for example, in beer dispensing.

According to paragraph 4 of the claims, the slide valve may have a cross-sectional profile in the valve body, for example a swallow tail profile, in order to provide guidance in the respective groove within the valve body. The connection sockets in the lower part of the valve body may be provided with cylindrical inserts for sealing against the lower surface of the spring-operated slide. Finally, according to the invention, the entire device according to the invention can be equipped with a connection sleeve of a patch of the patches, which has an extension * for direct use with the beverage. List of drawings in the drawing

BRIEF DESCRIPTION OF THE DRAWINGS The invention is explained in more detail with reference to the drawings, in which preferred embodiments of the device are illustrated.

The drawings are. 1 is a side elevational view of the device according to the invention. FIG. 2 and 3 show a longitudinal section and a cross-sectional view of the device of FIG. FIG. Figures 4 and 5 show respective sections as shown in Figures 2 and 3 in the emptying and cleaning state, Fig. 6 shows a cross section of the inventive device of the valve slide, swallow tail face, Figs. the device according to the invention. EXAMPLES OF THE INVENTION

As can be seen from the drawing, the device according to the invention consists of a valve body 1 which is designed as a block in which the I-shaped groove 2 is arranged to accommodate a correspondingly formed T-shaped valve slide 2, in the lower part of the housing 1. the valve 4 is a beverage supply connection 4, which is mounted directly on the beverage container extension 2, for example a beer barrel. Under connection 2, the carbon dioxide dioxide CO 2 supply, which is not shown in the carbon dioxide CO 2 <RTIgt;

Directly on the upper side of the valve slide 2, a cylindrical container 2 is arranged above the bore 2 in the slide 2, in which there are resilient, spherical cleaning elements 10, for example small balloons or sponges. on the bottom 2 of the valve body 1, a threaded connection 14 for supplying the cleaning water 15 is provided in addition to the beverage supply v4.

In order to ensure the function of the device according to the invention, the threaded connection 14 for the supply of cleaning water and the connection-6- 4 for the supply of beverages in the lower part of the valve body 1 has the same distance as the two bores or 11 in the valve stem of the valve step. Further, a pressure piston 16 is provided in the valve body 1, the connection 17 of which is connected to a carbon dioxide bottle (not shown). The actuation of the pressure piston 16 can be effected by means of a remote control device (not shown), so that the device can be inside the valve. the radius is controlled from anywhere.

In particular, as shown in FIG. 2, a spherical, elastic cleaning body storage space 18 is provided in the upper portion of the cleaning water supplying neck 14, which falls from the tubular container in the further operating position described below. Furthermore, the connecting sleeves 4 and 14 have cylindrical bushings 21, 22, which are spring loaded in a screw-like manner, which are pressed closer to the lower surface of the slide for sealing.

The operation of the device according to the invention is now explained by means of FIG. 2 to 5.

In FIGS. 2 and 3, which represent the operating position, the reservoir sits in accordance with the water connection 14, so that the cleaning body 10 falls into the upper space 18 by the force of gravity. The bore 11 is aligned with the connection 4 so that it extends from the beverage container 6, the beverage is guided in the direction of the arrow 24 by the flexible line 13 to the tap,

Figures 4 and 5 show the cleaning state or the

The gate 2 moves in the direction of the double arrow 25 towards the left so that the outlet of the container is closed by the base of the valve body 1. Furthermore, the connection 4 for the supply of beverages is closed by the base 23 of the slide 2 * of the connection socket 12 with the bore 11 located in a position above the water inlet connection 14. The pressure of the water column presses the cleaning body 10 upwardly into the flexible line 13a from there to the tap. The boundary between the protruding water column and the beverage column not in line 13 forms a spherical, flexible cleaning body 10. ,

Thus, a tap-tap operator may use an even beverage in the beverage line 13. It may be used until the cleaning body 10 exits the tap on the tap. When the amount of beverage present is predetermined, the tapper knows exactly how much beverage it can deliver. For this reason, the device according to the invention works without loss of beverages.

FIG. 6 is a cross-sectional view of another embodiment of the invention in accordance with FIG. 5. The slide 3 &apos; is formed in the shape of a tail tail and moves in a corresponding recess 2 formed by the swallow tail. Of course, other embodiments of the slide are possible. What is important here is that it is unambiguously guided in the valve body 1

It is also possible to form the slide as a rotary slide, the valve body 1 then having a circular shape, and correspondingly connecting connectors.

The device according to the invention is arranged not only for dispensing beverages, for example for tapping beer, but can also be used more or less for liquids and liquids such as milk, dairy products or the like. The intended use is / 2 especially for industrial production and treatment of liquids and nutrients, such as milk concentrates for beverage manufacturers and

Figures 7 to 9 show a modified embodiment of an apparatus according to the invention using a rotary slide valve.

The rotary slide 26 is located there inside the valve body 28, indicating a semicircle-shaped region 27. The bent connection piece 29 leads to a flexible beverage conduit to the tap The beverage conduit 4 and the purge nozzle 14 are arranged in the lower part of the valve body 28, instead of the longitudinal movement, the slide 24 performs a rotary movement to connect the connection piece 4 with a bent connecting sleeve 29 or after a rotational movement to connect the cleaning water supply connection 14 with the cleaning body 10 contained therein to the connection sleeve 29. Two pressure connections 30, 31 are provided for this purpose, behind which in suitable Pressure pistons 32, 33 are connected to the spherical balls 34, which abut against the rotary slide piece 35, respectively. polo-hy. In this way, the above-described rotational movement of the connecting sleeves 4,14 is also canceled.

It is, of course, also possible, in a variation to the embodiment shown in FIGS. 2 and 4, to make the distance between the threaded inlet 14 for the purge water and the beverage inlet 4 in the lower part of the valve body 1 greater than the distance between the two through bores 8, 11 in the valve slider 2. In essence, it is found that only for the introduction of the cleaning body 10 of the space 18, the container 2 and the water connection 14 are stacked one above the other, the displacement path being slightly longer. -

A further change of the device according to the invention may be that a control valve is provided in the water supply line to the water connection 14, which is then closed when the container 6 is above the water connection 14. In this way, the space 2 of the container 2 can be kept free from water pressure during the fall of the cleaning body 10 downwards.
