Description

Flow switch for manual filling of foaming and carbonated drinks

The invention relates to flow switches in devices for dispensing beer and other foaming and carbonated drinks from an isobaric container into plastic bottles at retail stalls, in stores, restaurants and bars and can be used in the food industry and commercial equipment.

Known devices for switching flows used in systems for simultaneous bottling of drinks of different varieties (Certificate for a utility model of the Russian Federation N ° 13369, IPC B 67 D 1/00, publ. 10.04.2000; US Patent .426164083, IPC B 67 D 5 / 62, publ. 12/26/2000), including a set of valves, each of which is installed in the pipeline connected to the container with the drink. Each container contains a specific beverage.

However, such devices for switching flows are inconvenient in operation while simultaneously dispensing over two kinds of drinks.

Known multi-way valve for switching flows (RF Patent M> 2175735, IPC F 16 K 1 1/074, publ. 1 October 1, 2001), comprising a housing with an inlet and several outlet pipes, a cover, a rotary spindle, a shutter made in in the form of two ceramic disks in contact with each other. One of the disks is fixedly mounted in the saddle of the casing, and the second is installed with the possibility of interaction with the rotary spindle. In the fixed disk, several through windows are made, in the moving disk there is a recess for communication between the pipes.

The disadvantage of such a flow switch is the ability to mix flows when switching them, as well as the low reliability of the three-way disk valve when it is use for bottling and the complexity of its technological maintenance associated with washing discs and seals after bottling of beer or other beverage.

A well-known flow switch device for manually dispensing foaming and / or carbonated drinks (made in the form of a replaceable cartridge) contains a cylindrical body with a lid, in the bottom of which there are two through supply holes and one outlet hole, as well as a rotatable upper disc mounted in the housing and the lower disk, which is stationary; the upper disk is rigidly connected through a hole in the lid with a handle located outside the multi-way valve body; in the lower disk, through holes are made coaxially with the holes in the bottom of the case, in the body of the upper disk, on the side of the lower disk and opposite its openings, a blind crescent-shaped groove is made for communication of one from the supply openings of the housing with its outlet, and around the handle under the housing cover there is an annular elastic seal for pressing the upper and lower disks against each other and to the bottom of the housing, and elastic sealing rings are installed in the openings of the bottom of the case (RF patent for utility model N ° 36371).

The disadvantage of this device is the low reliability of the three-way disk tap cartridge designed for bottling and the complexity of its technological maintenance associated with washing discs and seals after bottling of beer or another drink.

A device for manually filling foaming and / or carbonated drinks (RF patent N ° 2337053, IPC V67SZ / 10, publ. 05/10/2008), containing a three-way cam switch streams. The device includes a housing having a channel connected to a gas supply pipe from a gas cylinder, a channel connected to a pipe supplying a drink from an isobaric tank, a drain channel connected by an additional channel to channels connected to a gas and beverage supply pipe, and a nozzle for attaching a neck of a plastic bottle to the open end of the drain channel, located on the housing near the drain channel, a throttle valve installed in the housing and connected to the drain channel, and a unit for extinguishing foam, placed in the drain nom channel. The channels connected to the gas and beverage pipelines are equipped with valves installed in them, the rods of which are kinematically connected to a profiled eccentric located in the cavity of the body of the beverage dispensing mechanism on the shaft, one end of which is passed through a sealed hole in the body wall and is rigidly connected to the control handle . The profile of the eccentric is made with the possibility of alternately opening the valves or finding them in a closed state.

However, this device has insufficient durability and reliability of the design of the device for filling the drink. It has a sufficiently large contact surface of the moving parts of the mechanism for switching flows with a poured beverage (all surfaces of the valves and cam), which causes a decrease in their durability and increased wear in the friction pair, the profiled eccentric and valve and, as a result, the wear products get into the poured beverage . In addition, it is known that on the surface of equipment made of metal and used in the production of beer and its storage and bottling, a bloom of beer is formed, which undesirably affects both the quality of the beer and technical indicators of the equipment itself. In the beer stone growing on the surface with prolonged non-removal of it, extraneous bacteria not characteristic of beer appear that affect the taste and color properties of beer. The equipment itself, on the surface of which deposits of beer stone appeared, becomes less durable and short-lived

(http://www.beermarket.net.ua/fomm/viewtopic.php?f=24&t=280)

The closest technical solution (prototype) is a three-way valve for switching flows of the apparatus for manual filling of foaming and carbonated drinks (international application WO2015 / 156697, IPC F16K1 1/00, published on October 15, 2015). The three-way flow switch contains axisymmetric cavities with seats and valves installed in the seats, spring-loaded with springs, the rods of which are kinematically connected to the profiled surface of the rotary element, rigidly connected to the control handle for alternately opening the valves or ensuring that the valves are in the initial closed state. Axisymmetric cavities with saddles are connected by internal channels to a drain channel and gas and beverage pipelines. A three-way flow switch is installed in the casing of the apparatus for manual filling of foaming and carbonated drinks with the possibility of extraction from the specified casing. Axisymmetric cavities with seats for accommodating valve gates are located in the internal channels of the flow switch across the channels; sections of valve stems with springs and a rotary element are located outside the cavities of the internal channels of the flow switch. Valves with rods and a rotary element in contact with them are made of thermoplastic having a permissible compressive stress

MPa Rod contact surface valves with a profiled surface of the rotary element is made developed as a section of the curve of the second order.

However, such a device also has insufficient durability and reliability of the design of the flow switch. It has a contact surface of the moving parts of the mechanism for switching flows with a bottled beverage (valve surfaces), which causes a decrease in their durability and increased wear. In addition, as mentioned above, on the surface of the equipment used in the bottling of beer, a deposit of beer stone is formed, which undesirably affects both the quality of the beer and the technical performance of the equipment itself. Equipment on the surface of which deposits of beer stone appeared becomes less durable and short-lived

(http://www.beermarket.net.ua/fo).

The technical result of the invention is to increase the durability, reliability and maintainability of the flow switch of the apparatus for manual bottling of a drink by eliminating contact of valve parts with foaming and carbonated drinks using an insulating elastic membrane.

The specified technical result is achieved in that the flow switch of the device for manual filling of foaming and / or carbonated drinks, according to the invention, contains a hollow cylindrical body with a lid, in the bottom of which there are two or more through inlets and one outlet openings located radially and at the same distance from the axis of the housing for their connection, respectively, with the inlet and outlet channels of the beverage dispenser, and also coaxially mounted in the housing a disk with the possibility of its rotation and a fixed pressure plate with through holes, placed with the formation of a cavity above the inlet and outlet holes in the bottom of the housing; valves with the possibility of their reciprocating movement are installed in the through holes of the pressure plate, and an elastic-elastic membrane with convex-concave pockets is located between the surface of the pressure plate and the bottom of the flow switch housing; through holes in a fixed pressure plate and pockets of an elastic-elastic membrane are located opposite and coaxial to the inlet holes in the bottom of the housing; the pockets of the elastic membrane are mounted on the valves of the pressure plate or are made at the same time from the same material, and the cam disk is rigidly connected to the shaft, which is led out through the hole in the cover out of the body of the flow switch, and has in the body from the side of the surface in contact with the surface stationary pressure plate, a blind hole, located with the possibility of alternating coaxial alignment with the through holes of the stationary pressure plate when the cam disc is rotated.

The cam disk is equipped with a position lock when the blind hole made therein is aligned with the through holes of the fixed pressure plate, which are curved elastic elements with protrusions made in the body of the cam disk on the side of its cylindrical surface and cavity on the inner cylindrical surface of the flow switch housing, located in one plane.

In the first embodiment, the flow switch can be made in the form of a removable cartridge with the possibility of placement in cavities of the detachable part of the casing of the device for manual filling of foaming and carbonated drinks.

In the second embodiment, the flow switch housing is located in the cavity of the detachable part of the casing of the device for manual filling of foaming and carbonated drinks, is made at the same time as the body of the specified detachable part of the casing of the specified device and from the same material.

In FIG. 10 shows a device for manual bottling of a drink, where the flow switch is made in the form of a removable cartridge.

The flow switch in the device for manual filling of foaming and carbonated drinks contains a hollow cylindrical case (1) with a cover (2), in the bottom (3) of which there are two or more through input (4) and one output (5) holes located radially and at the same distance from the axis of the case (1), for connecting them, respectively with inlet (6) and outlet (7) channels of the bottling device. In the housing (1), a coaxial cam disk (8) is mounted with the possibility of its rotation and a fixed pressure plate (9) with through holes (10) placed to form a cavity (1 1) above the inlet (4) and outlet (5) holes in the bottom (3) of the housing (1). In the through holes (10) of the pressure plate (9), valves (12) are installed with the possibility of their reciprocating movement. An elastic-elastic membrane (13) with convex-concave pockets (14) is located between the surface of the clamping fixed plate (9) and the bottom (3) of the housing (1). The through holes (10) in the fixed pressure plate (9) and the pockets (14) of the elastic-elastic membrane (13) are located opposite and coaxial to the inlet holes (4) in the bottom (3) of the housing (1). In the pockets (14) of the elastic-elastic membrane (13), the valves (12) of the pressure plate (9) are fixed or are made integrally with them from the same material.

The cam disk (8) is rigidly connected to the shaft (15), brought out through the hole in the cover (2) to the outside of the housing (1) of the flow switch. A blind hole (16) is made in the body of the cam disk (8) from the side of the surface in contact with the surface of the fixed pressure plate (9), which is arranged to alternately coaxially align with one of the through holes (10) of the stationary pressure plate (9) when turning cam disc (8).

The cam disk (8) is equipped with a position lock when the blind hole (16) made in it is aligned with the through holes (10) of the fixed pressure plate (9), which are curved elastic elements (17) with protrusions (18), made in the body of the cam disk (8) from the side of its cylindrical surface and cavity (19) on the inner cylindrical surface of the housing (1 ) flow switch located in one plane. The housing (1) with a cover (2), a cam disk (8), valves (12) and a fixed pressure plate (9) can be made of metal or plastic, and the elastic-elastic membrane (13) is made of elastic-elastic plastic, for example elastomer.

In one embodiment (Fig. 10), the flow switch together with the housing (1) can be made in the form of a removable cartridge (20) with the possibility of placing it in the cavity of the detachable part (21) of the housing (22) of the device for manual filling of foaming and / or carbonated drinks.

In another embodiment (Fig. 9), the housing (1) is placed in the cavity of the detachable part (21) of the housing (22) of the device for manual bottling of drinks and is made integral with the body of the specified detachable part (21) and of the same material.

Below is a more detailed description of the remaining components and parts of the device for manual bottling of beverages. The inlet channels (6) and the outlet channel (7) are located in the lower part (23) of the body of the body (22) of the beverage dispenser. One supply channel (6) is connected to the beverage supply fitting, and the other supply channel (6) to the gas supply fitting (not shown in the drawings). The discharge channel (7) has an annular outlet (24) for filling the beverage and supplying gas to the consumer container (not shown in the drawings). The axial channel (25) in the housing (22) of the device is designed to remove gas from consumer capacity into the atmosphere through an adjustable throttle valve (26). The upper detachable part (21) of the body of the housing (22) is kinematically connected with its lower part (23) by means of a threaded connection. Around the lower part (23) of the body of the housing (22), the movable part (27) of the housing (22) with the control handle (28) is rotatably and reciprocally connected kinematically to the lower part (23), for example, by means of a bayonet or threaded connection. The movable part (27) of the housing (22) is made in the form of a hollow cylinder and contains a C-shaped spoon (29) in its end to capture the neck of the consumer container and its connection with the output ring part (24) of the outlet channel (7). Around the output annular part (24) of the outlet channel (7) there is a sealing elastic-elastic ring element (30) for hermetically connecting the neck of the consumer container with the ring part (24) of the outlet channel (7). The control knob (31) is rigidly fixed to the shaft (15) of the cam disk (8) of the flow switch.

To supply a drink of two varieties, a flow switch with three supply channels can be used to supply a drink of two varieties (Fig. 8).

A device for manual filling of foaming drinks, including the inventive flow switch, operates as follows. In the neutral position of the handle (31), the inlet openings (4) of the supply channels (6) of the flow switch are closed (Fig. 5). The neck of the container is installed under the annular output part (24) of the beverage supply channel 7 in the groove of the movable part (27) of the housing (22). In this case, the C-shaped spoon (29) captures the container by the flange of its neck. Then turn the handle (28) with which it rotates and the movable part (27) of the body (22) rises up with a spoon (29), tightly pressing the neck of the container behind the annular flange to the annular elastic-elastic element (30), connecting the cavity of the consumer capacity with the annular outlet part (24) of the channel (7). In this case, the throttle (26) is closed. The flow control knob (31) is in the neutral position. Then turn the handle (31) of the flow switch together with the cam disk (8) to the first fixed position of its elements (17) in the troughs (19) of the housing (1), where a blind hole (16) is installed above the valve (12), which through the elastic the membrane (13) under the action of gas pressure coming from the channel (6) rises up and enters the specified blind hole (16), opening gas access (Fig. 7) from the channel (6) through the cavity (1 1) into the channel (7) ) and further into the internal volume of consumer capacity. Wherein C0 ₂ gas is supplied from a cylinder into a consumer container in which the pressure equalized to a pressure in the keg with the beverage. Next, turn the handle (31) of the flow switch together with the cam disk (8) to the next fixed position of its elements (17) in the troughs (19) of the housing (1), where a blind hole (16) is installed above the valve (12), which through the elastic the membrane (13) under the influence of the pressure of the beverage coming from the channel (6) rises up and enters the specified blind hole (16), opening up the access of the drink (Fig. 6) from the channel (6) through the cavity (1 1) into the channel (7) ) and further into the internal volume of consumer capacity. In this case, the channel (6) with the nozzle of the beverage is communicated through the channel (7) with the internal volume of the consumer capacity. Since the pressure in the filled tank and the keg with the drink is the same, the flow of the drink into the indicated container does not occur. When opening the throttle valve (26) gas C0 ₂ (Fig. 10) is displaced from the tank into the atmosphere. A pressure drop is created in the keg with the drink and the consumer capacity due to which the drink fills the container. After filling the container with a drink, to stop its further entry from the keg, turn the handle (31) of the flow switch to the neutral initial position (Fig. 5) together with the cam disk (8) to the next fixed position of its elements (17) in the cavities (19) of the housing ( one). The remaining gas in the neck of the container and partially dissolved gas released from the drink are removed through the channel of the throttle valve (26) to the atmosphere. After equalizing the pressure in the tank to atmospheric, rotate the handle (28) of the movable part (27) of the device body (22) in the opposite direction, disconnecting the output ring part (24) of the channel (7) from the neck of the tank, which is removed from the filling device, and is closed with a stopper and released to the consumer.

After the operation of the device for manual filling of the drink does not require flushing the flow switch, because all moving parts of the switch are isolated from contact with the drink by means of an elastic-elastic membrane (13). After prolonged use and wear of the membrane (13), it can be replaced with a new one.

As can be seen from the description of the operation of the device, an increase in durability, reliability and maintainability of the flow switch of the apparatus for manual bottling of a drink is achieved by eliminating the contact of valve parts with foaming and carbonated drinks using an insulating elastic membrane (13).
