Description

Technical Field

[0001] This utility model belongs to the field of fluid medium control technology, and specifically relates to a flow regulating device and a beer tap. Background Technology

[0002] Beer taps are commonly found in bars, craft breweries, or home brewing facilities. They are installed on beer kegs or beer machines to control the flow of beer, regulate the flow rate, and adjust the foam.

[0003] For example, Chinese Patent No. CN207121417U discloses a beer tap, which includes a valve body with a conveying channel. The valve body is provided with a flow regulating body, and multiple liquid guiding grooves communicating with the arc-shaped concave surface are opened on the outer wall of the flow regulating body. A distributing head is connected to the valve body and located at the inlet end of the conveying channel. The distributing head is provided with a liquid inlet channel that is coaxial with and communicates with the conveying channel. The liquid outlet end of the liquid inlet channel is a conical channel. The tip of the conical flow regulating body is provided with a flow stabilizing head, which is inserted into the conical channel of the liquid inlet channel.

[0004] The above technical solution has the following drawbacks: the beer tap requires the connecting shaft to be inserted into the mounting hole on the flow regulator. During assembly, the flow regulator needs to be constantly adjusted so that the mounting hole on the flow regulator is aligned with the connecting shaft. It is difficult to quickly insert the connecting shaft into the mounting hole on the flow regulator, making assembly inconvenient and inefficient. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a flow regulation device. The technical problem to be solved by this invention is: how to improve assembly efficiency.

[0006] The above-mentioned technical objective of this utility model can be achieved through the following technical solution: a flow regulating device, including a valve body, a knob, and a flow regulating body. The valve body is provided with a conveying channel, and the flow regulating body is slidably disposed in the conveying channel. The conveying channel is provided with a connecting port for the medium to pass through. The flow regulating body can slide to control the connecting area of ​​the connecting port. The knob is rotatably disposed on the valve body. A connecting shaft is eccentrically disposed at the end of the knob. An annular groove is opened on the outer wall of the flow regulating body, and the connecting shaft is inserted into the annular groove.

[0007] In one of the flow regulating devices described above, the sidewall of the flow regulating body is provided with at least one horizontal surface, and the medium can pass through between the horizontal surface and the inner sidewall of the valve body.

[0008] In one of the flow regulating devices described above, the end of the connecting shaft is spherical.

[0009] A beer tap includes a flow regulating device as described above. The valve body is provided with a medium inlet and a medium outlet communicating with the conveying channel. The conveying channel is provided with a control port for controlling the passage of the medium. A valve stem and a valve core are slidably disposed in the conveying channel. The valve stem drives the valve core to slide, thereby controlling the opening and closing of the control port.

[0010] In the aforementioned beer tap, a sealing surface is provided inside the valve body, and the valve core can abut against the sealing surface to form a seal and block the control port.

[0011] In the aforementioned beer tap, the valve stem passes through the valve core, and the valve stem is provided with a limiting part for axially limiting the valve core.

[0012] In the above-mentioned beer tap, the other end of the valve stem is connected to a positioning end cap, the valve body is provided with a positioning step, and a second spring is provided between the positioning end cap and the positioning step. The positioning end cap can cooperate with the positioning step to compress the second spring.

[0013] In the aforementioned beer tap, the valve body is provided with a balance channel one and a balance channel two. The balance channel one connects the medium outlet and the conveying channel, and the balance channel two connects the outside world and the conveying channel. When the valve stem drives the valve core to slide and control the control port to open, the valve stem separates the balance channel two from the conveying channel.

[0014] In the aforementioned beer tap, a lever is oscillating on the valve body. The oscillation of the lever can drive the valve stem to slide. A linkage hole is provided on the valve stem, and the end of the lever is inserted into the linkage hole.

[0015] In the aforementioned beer tap, the lever is provided with a spherical part, the valve body is provided with a spherical groove, and the spherical part is rotatably disposed within the spherical groove.

[0016] In summary, the beneficial effects of this utility model compared to the prior art are as follows:

[0017] By creating an annular groove on the outer wall of the flow regulator, the connecting shaft can be directly inserted into the annular groove during assembly without adjusting the position of the flow regulator. This simplifies operation, facilitates assembly, and effectively improves assembly efficiency. The annular groove on the flow regulator is designed to mate with the connecting shaft, thus reducing the material consumption in the manufacture of the flow regulator and lowering production costs.

Detailed Implementation

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments. Example 1:

[0028] A flow regulating device, such as Figures 1 to 4 As shown, the device includes a valve body 1, a knob 2, and a flow regulating body 3. The valve body 1 has a conveying channel 4, and the flow regulating body 3 is slidably disposed within the conveying channel 4. The conveying channel 4 has a connecting port 5 for the medium to pass through. The sliding of the flow regulating body 3 can control the connecting area of ​​the connecting port 5. Specifically, by sliding the flow regulating body 3, the gap between the flow regulating body 3 and the connecting port 5 is changed, thereby controlling the connecting area of ​​the connecting port 5 and thus adjusting the flow rate.

[0029] Regarding how the flow regulating body 3 slides, it should be noted that the knob 2 is rotatably mounted on the valve body 1, and a connecting shaft 6 is eccentrically mounted at the end of the knob 2. An annular groove 7 is provided on the outer wall of the flow regulating body 3, and the connecting shaft 6 is inserted into the annular groove 7. When the knob 2 is rotated, the connecting shaft 6 eccentrically mounted at the end of the knob 2 rotates and contacts the inner wall of the annular groove 7, thereby pushing the flow regulating body 3 to slide.

[0030] Furthermore, the end of the connecting shaft 6 is spherical, and the spherical structure contacts the inner wall of the annular groove 7, which can effectively reduce wear and improve service life.

[0031] It should be further explained that in the prior art, mounting holes are usually made on the flow regulator 3 to mate with the connecting shaft 6. Therefore, during assembly, the position of the flow regulator 3 needs to be constantly adjusted so that the mounting hole is aligned with the connecting shaft 6 before the connecting shaft 6 can be inserted into the mounting hole to complete the assembly. This is inconvenient and has low assembly efficiency. In this embodiment, however, an annular groove 7 is used to mate with the connecting shaft 6. Therefore, the connecting shaft 6 can be directly inserted into any position in the annular groove 7 without the need to adjust the position of the flow regulator 3. This simplifies the operation, makes assembly convenient, and effectively improves assembly efficiency. Moreover, since the annular groove 7 needs to be made on the flow regulator 3, the manufacturing materials for the flow regulator 3 will be relatively reduced, and the production cost will be relatively lower.

[0032] The flow regulating body 3 has at least one horizontal surface 8 on its side wall. The horizontal surface 8 and the inner side wall of the valve body 1 allow the medium to pass through. In this embodiment, there are several horizontal surfaces 8 evenly distributed circumferentially along the flow regulating body 3, and the horizontal surfaces 8 extend to the end of the flow regulating body 3. It should be noted that the number of horizontal surfaces 8 can be increased or decreased according to actual needs, and there is no specific limitation on this. The horizontal surfaces 8 can guide the medium through. Alternatively, the horizontal surface 8 can also be a curved surface. Example 2:

[0033] A type of beer tap, such as Figures 5 to 8 As shown, the beer tap includes the above-mentioned flow regulating device. The valve body 1 is provided with a medium inlet 9 and a medium outlet 10 that connect to the conveying channel 4. The conveying channel 4 is provided with a control port 11 for controlling the passage of the medium. Along the medium conveying direction, the control port 11 is located between the medium inlet 9 and the medium outlet 10.

[0034] A valve stem 12 and a valve core 13 are slidably installed in the conveying channel 4. The valve stem 12 drives the valve core 13 to slide, which can control the opening and closing of the control port 11. By controlling the opening and closing of the control port 11, the beer tap can be turned on and off.

[0035] Specifically, a sealing surface 14 is provided inside the valve body 1. The valve core 13 can abut against the sealing surface 14 and form a seal to block the control port 11. In this embodiment, the valve core 13 includes a base 131 and a sealing gasket 132. The sealing gasket 132 is installed on the base 131. By abutting against the sealing surface 14, the valve core 13 blocks the control port 11, that is, the control port 11 is in a closed state. It should be noted that the sealing performance can be effectively guaranteed by the cooperation of the sealing gasket 132 and the sealing surface 14. Conversely, if the valve core 13 is away from the sealing surface 14, the control port 11 is in an open state.

[0036] The valve stem 12 passes through the valve core 13. A limiting part 15 for axially limiting the valve core 13 is integrally provided on the valve stem 12. The end face of the limiting part 15 abuts against the end face of the valve core 13, thereby achieving axial limiting of the valve core 13.

[0037] One end of the valve stem 12 is connected to a positioning sleeve 16. A spring 17 is provided between the positioning sleeve 16 and the valve core 13. One end of the spring 17 abuts against or is connected to the positioning sleeve 16, and the other end of the spring 17 abuts against or is connected to the valve core 13. It should be noted that by applying force to the valve core 13 by the spring 17 and cooperating with the limiting part 15 to limit the axial movement of the valve core 13, the position of the valve core 13 on the valve stem 12 can be effectively guaranteed to be stable.

[0038] The other end of the valve stem 12 is connected to a positioning end cap 18. A positioning step 19 is provided inside the valve body 1. A second spring 20 is provided between the positioning end cap 18 and the positioning step 19. The positioning end cap 18 can cooperate with the positioning step 19 to compress the second spring 20. One end of the second spring 20 abuts or connects with the positioning step 19, and the other end of the second spring 20 abuts or connects with the positioning end cap 18.

[0039] It should be noted that when the beer tap is closed, that is, the valve core 13 abuts against the sealing surface 14 and forms a seal, the valve core 13 blocks the control port 11. When the beer tap needs to be opened, the valve core 13 is moved away from the sealing surface 14 by the sliding of the valve stem 12, so that the control port 11 is opened.

[0040] Regarding how the valve stem 12 drives the valve core 13 to slide, it should be noted that since the valve core 13 abuts against the limiting part 15, the limiting part 15 can push the valve core 13 to slide while sliding with the valve stem 12. The sliding of the valve stem 12 also drives the positioning sleeve 16 and the positioning end cover 18 to slide. The valve core 13 pushes the spring 17 to slide, and the positioning end cover 18 cooperates with the positioning step 19 to compress the spring 20. When the external force applied to the valve stem 12 is removed, the elastic restoring force of the spring 20 causes the positioning end cover 18 to slide back to its original position. The positioning end cover 18 drives the valve stem 12 to slide back to its original position, the valve stem 12 drives the valve core 13 and the positioning sleeve 16 to slide back to their original position, and the positioning sleeve 16 drives the spring 17 to slide back to its original position.

[0041] The specific method for enabling the user to control the sliding of the valve stem 12 is as follows: A lever 23 is oscillating on the valve body 1. The oscillation of the lever 23 can drive the valve stem 12 to slide. A linkage hole 24 is opened on the valve stem 12. The end of the lever 23 is inserted into the linkage hole 24. That is, the user only needs to oscillate the lever 23, and the end of the lever 23 can push the valve stem 12 to slide.

[0042] The lever 23 is integrally provided with a spherical part 25, and the valve body 1 is provided with a spherical groove 26. The spherical part 25 is rotatably disposed in the spherical groove 26. Through the cooperation between the spherical part 25 and the spherical groove 26, the lever 23 can swing relative to the valve body 1, and the lever 23 is restricted from detaching from the valve body 1.

[0043] The valve body 1 is provided with a balance channel 1 21 and a balance channel 22. The balance channel 1 21 connects the medium outlet 10 and the conveying channel 4, and the balance channel 22 connects the outside world and the conveying channel 4. When the valve stem 12 drives the valve core 13 to slide and control the control port 11 to open, the valve stem 12 will separate the balance channel 22 and the conveying channel 4.

[0044] During the dispensing process, the outlet pipe at the lower end of the medium outlet 10 is usually inserted into the wine glass. Due to the pressure difference, when the control port 11 is closed, there will still be residual medium in the medium outlet 10. By opening the balance channel 1 21 and the balance channel 2 22, the outside gas can first enter the conveying channel 4 through the balance channel 2 22, and then enter the medium outlet 10 through the balance channel 2 22, so that the medium outlet 10 is balanced with the outside air pressure, thereby allowing the residual medium in the control port 11 to be discharged smoothly. When the control port 11 is open, the valve stem 12 blocks the connection between the balance channel 2 22 and the conveying channel 4, thereby isolating the two and preventing the medium in the conveying channel 4 from being discharged normally from the medium outlet 10.

[0045] The specific embodiments described herein are merely illustrative examples of the spirit of this utility model; those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, but without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
