In the two positions, one of the supply channels is connected to the discharge channel, in the third position, all the channels being disconnected. A foam suppression unit is arranged in the cavity of a pouring cylinder and is designed in the form of a nozzle with an axial channel and a cylindrical section, which cylinder is provided with a screw-type pouring channel. The device comprises a throttle valve connected to the axial through channel of the nozzle and a mechanism for fastening the neck of a plastic bottle to the pouring channel which is additionally provided with an inner sleeve.

Description

a sickle-shaped blind groove is made to connect one of the intake openings of the housing with its outlet opening. Around the handle under the housing cover is an annular elastic seal for pressing the upper and lower disks to each other and to the bottom of the housing, and elastic sealing rings are installed in the holes of the bottom of the housing. The mechanism for attaching the neck of a plastic bottle to the end of the drain channel contains an elastic ring element attached to the end of the drain channel coaxial with its outlet and a spoon with a handle and a groove corresponding to the size of the neck of the plastic bottle, and the cylindrical part of the spoon is located around the end of the drain channel near the outlet and kinematically connected to the wall of the drain channel by a bayonet connection, and the slot of the spoon is located in front of the outlet of the drain channel. The bayonet connection is a blind screw groove made in the wall of the drain channel, in which an axis with a roller is installed, attached to the cylindrical part of the spoon of the plastic bottle neck attachment mechanism. The specified mechanism allows to hermetically connect the neck of the plastic bottle with the end of the drain channel of the device for manual pouring of foamy and/or carbonated drinks. The unit for extinguishing foam of the beverage dispensing device includes a nozzle with a through axial channel, having an outer cylindrical part with a helical groove on the side surface, and a shank forming an annular cavity between its outer surface and the surface of the drain channel. Elimination of foaming is ensured by the creation of gas pressure in the dispensing system and above the surface of the drink in a plastic bottle, which exceeds the saturation pressure of the gas dissolved in the drink and prevents the liquid from "boiling". The node for quenching the foam due to centrifugal forces ensures the supply of the drink in the form of a film on the walls of the plastic bottle, which reduces the turbulence of the liquid flow.

The disadvantage of such a device is the low reliability of the three-way faucet-cartridge of the device for pouring a drink due to the formation of beer and wine stones between the moving plates of the cartridge and the complexity of its technological maintenance associated with frequent washing of discs and seals after the end of pouring beer or another drink, as well as insufficient reliability of the mechanism for attaching the neck of the plastic bottle to the end of the drain channel of the device due to the fact that during the process of clamping the PET bottle, when the control handle is turned, the PET bottle held by the operator's hand rotates together with the body of the mechanism and the spoon, which often leads to the PET bottle slipping out of the hand the operator

The technical result of the invention is the creation of such a device for manual pouring of a drink into PET bottles, which would have a higher reliability of operation due to the reduction of the contact surface of the moving parts of the three-way faucet parts, which reduces their wear and eliminates the rotation of the PET bottle at the moment of its compression by the fastening mechanism of the plastic neck bottles to the end of the drain channel, as well as easier technological maintenance of this device, which is associated with a reduction in the frequency of washing the components and parts of this mechanism after the beer or other drink has been poured.

The specified technical result is achieved by the fact that the device for manual pouring of foamy and/or carbonated drinks includes a body in the body of which there are inlet channels with elements for connection according to the gas supply pipelines from the pressure source and the drink from the isobaric container, and an axisymmetric cavity, which has three sequentially located chamber rings, to the first and third of which channels are attached, which respectively supply gas to the drink, a drain cup, attached vertically in the lower part of the device body and which has an elastic seal on the open lower end, the inner cavity of which is connected by a drain a channel with a second annular chamber of an axisymmetric body cavity, a three-way valve, located in an axisymmetric body cavity and made in the form of a hollow spool with radial through holes with the possibility of longitudinal rotary-forward movement by the control handle and fixation in three positions, in two of which one of the supply channels connected with a discharge channel, in the third - with the possibility of disconnecting the supply channels, a node for extinguishing foam, placed in the cavity of the drain cup and made in the form of a nozzle with an axial through channel, a cylindrical part with a screw drain channel on the outer surface and a narrowing shank, a throttle valve, installed in the body and connected by its inlet channel to the through axial channel of the nozzle, and the mechanism for attaching the neck of the plastic bottle to the drain channel of the device, which includes an outer sleeve with a control handle located around the drain cup with the possibility of axial rotation, an inner sleeve located between the drain cup and an external sleeve with the possibility of axial rotary and translational movement, kinematically connected to the cylinder wall of the drain cup by means of a splined element and having a screw slot in the cylinder wall, in which there is a roller attached by a pin to the outer sleeve with a control handle and a spoon with a groove, corresponding p the size of the neck of the PET bottle, attached from below to the end of the inner sleeve, installed in front of the open end of the drain cup and the outlet of the screw drain channel.

Increasing the reliability of the device for pouring a drink consists in reducing the contact surface of the moving parts of the three-way faucet mechanism, which reduces their wear, and also provides freer access to all parts of the faucet mechanism in contact with bottled drinks, which simplifies its technological maintenance related to washing nodes and parts of the faucet mechanism after the beer or other drink is finished pouring.

The mechanism for attaching the neck of the PET bottle to the drain channel allows you to quickly and hermetically connect the neck of the plastic bottle to the end of the drain cup of the device for manual pouring of foamy and/or carbonated drinks without rotating the bottle, which, together with the spoon, performs only rotary-forward movement, which increases reliability of the device and ease of use of the mechanism.

The device is explained with the following graphic materials. In Fig. 1 shows a diagram of a device for manual pouring of foamy and/or carbonated drinks with a mechanism for attaching a plastic bottle, in Fig. 2 - the same, cut according to A-A. In Fig. C shows view A Fig. 1, where a local section of the plastic bottle neck fastening mechanism is presented. In Fig. 4 shows a section along B-B Fig. 1. On

PET bottle.

The device for manual filling of a beverage with reverse pressure in plastic PET bottles contains (Figs. 1 and 2) a body 1 installed, for example, on a stand (not shown in the drawings). In the body of the housing 1, inlet channels 2 and 3 with elements 4 and 5 are made for connection, respectively, with the gas supply pipelines from the pressure source and drink from the isobaric container, and an axisymmetric cavity b, which has three sequentially located annular chambers 7, 8 and 9 Channels 2 and 3 are connected to the first chamber 7 and the third chamber 9, which supply gas and drink, respectively. The drain cup 10 is attached vertically in the lower part of the housing 1 of the device and has an elastic seal 11 on the side of the open lower end, the inner cavity 12 of which is connected by a discharge channel 13 with the second annular chamber 8 of the axisymmetric cavity 6 of the housing 1. The three-way valve is located in the axisymmetric cavity 6 of the housing 1 and is made in the form of a hollow spool 14 with radial through holes 15 and 16 with the possibility of longitudinal rotary-forward movement by the control handle 17 and fixing it in three positions. In one of the positions of the spool 14 (Fig. b, b), channel 2, which supplies gas, is connected to the outlet channel 13, in the second position of the spool 14 (Fig. 6, c), channel C, which supplies the drink, is connected to the outlet channel 13 , and in the third (neutral) position (Fig. b, a) both supply channels 2 and 3 are disconnected. a drain channel 20 on the outer surface and a tapered shank 21. The throttle valve 22 (Fig. 2) is installed in the housing 1 and is connected by its inlet channel 23 to the through axial channel 19 of the nozzle 18. The mechanism for attaching the neck of the plastic bottle to the drain channel of the device (Fig. 2-5) contains an external sleeve 24 with a control handle 25 , located around the drain cup 10 with the possibility of axial rotation. The inner sleeve 26 of this mechanism is located between the drain cup 10 and the outer sleeve 24 with the possibility of axial rotary-translational movement, it is kinematically connected to the cylinder wall of the drain cup 10 with the help of a slotted element 27 and has a screw slot 28 in the cylinder wall, in which the roller is placed 29, attached by a pin 30 to the outer sleeve 24 with a control handle 25. A spoon 31 with a groove 32 corresponds to the size of the neck of a PET bottle, attached from below to the end of the inner hollow sleeve 26 and installed in front of the open end of the drain cup 10 and the outlet of the screw drain channel 20.

A device for manual bottling of foamy and/or carbonated beverages works as follows.

Take a plastic bottle, insert a spoon 31 into the groove 32 and turn the handle 25 together with the outer sleeve 24. At the same time, the roller 29, moving along the screw slot 28, moves the inner sleeve 26 with 25 spoon 31 up. The spoon 31 presses the end of the neck of the PET bottle to the end of the wall of the drain cup 10 and hermetically joins them due to the elastic ring seal 11 (without turning the PET bottle). At the same time, throttle 22 is closed. The handle 17 of the three-way faucet is in a (neutral) vertical position (Fig. 6, a). Then the handle 17 of the three-way faucet is deflected by 20 degrees (toward the operator), displacing the spool 14, as shown in Fig. 6, 6.

At the same time, the channel 2 is connected to the gas through the first annular chamber 7, radial holes 15, the inner cavity of the spool 14, radial holes 16, the outlet channel 13, the axisymmetric cavity 12, the screw drain channel 20 with the inner volume of the PET bottle. At the same time, CO gas from cylinder 5 enters the bottle, the pressure in which is equalized to the pressure in the isobaric container. Next, the handle 17 of the three-way faucet is tilted by 40 degrees, displacing the spool 14 in the opposite direction. At the same time, as shown in Fig. 6, in, the channel C is connected to the drink through the third chamber 9, the second chamber 8, the outlet channel 13, the axisymmetric cavity 12, the screw drain channel 20 with the internal volume

PET bottles.

Since the pressure in the PET bottle and the isobaric container is the same, the drink does not enter the specified container. When opening the throttle 22, CO gas is forced out of the PET bottle into the atmosphere through the axial channel 19, the inlet and outlet channels 23 of the throttle 22. A pressure difference is created in the isobaric container and the PET bottle, due to which the drink fills the bottle. Passing through the screw drain channel, the drink is fed in the form of a conical film to the walls of the PET neck under the action of centrifugal forces -

the bottle continues to flow smoothly down its walls, preventing foaming. Elimination of foaming is also ensured by creating a gas pressure in the dispensing system and above the surface of the drink in a plastic bottle, which exceeds the saturation pressure of the gas dissolved in the drink. After filling the bottle with a drink, in order to stop its further arrival from the isobaric container, the handle 17 of the three-way tap is turned to neutral (by 20 degrees), moving the spool 14 to the initial position, as shown in Fig. 6, a. The remaining gas in the neck of the PET bottle and the partially dissolved gas released from the drink are removed through the axial channel 19 of the nozzle 18 and channels 23 of the throttle 22 into the atmosphere. After equalizing the pressure in the PET bottle to atmospheric, turn the handle 25 in the opposite direction, disconnecting the end of the wall of the draining cup 10 from the neck of the PET bottle, which is removed from the filling device, closed with a cork and released to the consumer.

The device, in particular the three-way faucet, has a minimum number of parts with rubbing surfaces, is easily disassembled and washed in water or an antiseptic liquid. Thus, the proposed technical solution increases the reliability of the device for pouring a beverage with reverse pressure into plastic bottles and simplifies its technological maintenance, which is associated with reducing the frequency of washing the nodes and parts of this mechanism after the end of pouring beer or another drink.

The fastening mechanism allows you to manually quickly and hermetically connect the neck of the plastic bottle to the end of the drain channel wall of the device for manual pouring of foamy and/or carbonated drinks without turning the bottle, which significantly increases the reliability of fastening the PET bottle and the convenience of using the device.
