Description

Technical Field

[0001] The invention belongs to the technical field of wine and beverage equipment and relates to a faucet, in particular to an adjustable faucet for beer dispensing. Background Art

[0002] Beer taps, beer spears, dispensers and beer barrels are the main components of beer drinking equipment. The beer tap plays the role of switching and regulating flow.

[0003] For example, Chinese patent literature discloses a beer faucet [application number: 200520117480.6; authorization announcement number: CN2869462Y], which includes a valve body, a water inlet channel and a water outlet channel. The valve body is equipped with a connecting rod slider mechanism and a crank mechanism. The connecting rod slider mechanism includes a connecting rod, a slider, a screw and a spring. The slider is provided with a hole groove, one end of the connecting rod extends into the hole groove, one end of the slider is provided with a connecting rod head and a sealing gasket, the crank mechanism includes a conical body, a round shaft and a handle, the conical body is provided with a hole groove, one end of the round shaft is provided with a small shaft smaller than the conical body, and the head of the small shaft extends into the hole groove.

[0004] The above-mentioned beer tap realizes switching through a connecting rod slider mechanism and realizes flow regulation through a crank mechanism, which is not convenient to operate. In addition, because two sets of mechanisms are arranged in the valve body and the crank mechanism protrudes from the side of the valve body, the overall volume is large and the manufacturing cost is also high.

[0005] Chinese patent literature also discloses a beer tap [application number: 201720579637.X; authorization announcement number: CN207121417U], which includes a valve body with a liquid passage, a valve stem arranged along the axial direction of the liquid passage, a flow regulating body that can move axially in the valve body, and a conical shape with a flow stabilizing head at the tip of the conical shape. This beer tap has a valve stem and a flow regulating body in the valve body, which also makes the overall volume larger, the manufacturing cost higher, and the operation inconvenient. Summary of the invention

[0006] The purpose of the present invention is to address the above-mentioned problems existing in the prior art and to provide an adjustable beer dispensing faucet which has a compact structure, a small volume, a low manufacturing cost and is easy to operate.

[0007] The object of the present invention can be achieved by the following technical scheme: an adjustable beer dispensing faucet, comprising a valve stem and a valve body, wherein the valve body is provided with a liquid passage and a liquid outlet passage connected to the liquid passage, wherein the valve body is provided with a valve core arranged along the axial direction of the liquid passage, wherein the inner end of the valve stem is inserted into the matching hole of the valve core, and the outer end of the valve stem is extended out of the valve body, wherein the valve body is provided with a sealing surface for sealing the end of the valve core near the liquid outlet passage to separate the liquid passage from the liquid outlet passage, wherein the valve body is provided with a flow regulating plate located in the liquid passage, wherein the flow regulating plate has an axially penetrating liquid passage hole, wherein the valve core has a rod-shaped tail extending into the liquid passage hole, wherein the inner end of the valve stem is threadedly connected with a slider located in the matching hole, wherein the slider is circumferentially limited with the matching hole and the outer surfaces of the two ends of the slider symmetrically arranged along the axial direction of the liquid passage are spherical or arcuate surfaces, wherein the hole wall of the matching hole has an arcuate surface for the spherical or arcuate surfaces at both ends of the slider to contact, and wherein an adjusting structure capable of changing the liquid passage flow rate when the tail is axially displaced is provided between the tail and the flow regulating plate.

[0008] When the adjustable beer dispensing faucet is closed, the end of the valve core close to the liquid outlet channel is sealed on the sealing surface, the valve core and the sealing surface separate the liquid passage and the liquid outlet channel, and the liquid outlet channel cannot discharge liquid; when liquid needs to be discharged for the first time, the valve stem is pulled toward the liquid outlet channel side, and the slider at the inner end of the valve stem hits the matching hole of the valve core, so that the valve core is away from the sealing surface, and the liquid passage and the liquid outlet channel are connected. At this time, the valve stem is rotated, and the slider is displaced at the inner end of the valve stem. Because the slider and the valve core are limited circumferentially, and the tail is extended into the liquid passage hole, the slider will drive the valve core and the tail to move axially along the liquid passage, and the regulating structure changes the liquid flow rate, so as to achieve the purpose of regulating the liquid outlet flow rate; after the liquid is discharged, the valve stem is pulled back to the liquid passage side, the valve core is re-sealed on the sealing surface, and the adjustable beer dispensing faucet is closed; because the adjustment of the liquid outlet flow rate has been completed after the first use, the valve stem is directly pulled to drive the valve core to seal or move away from the sealing surface in the next use, so as to realize the opening and closing of the adjustable beer dispensing faucet. During use, the spherical surfaces or arcuate surfaces at both ends of the slider and the arcuate surface of the matching hole abut against each other reliably without causing interference, and the working stability is good.

[0009] The adjustable beer dispensing faucet can achieve the functions of opening and closing and flow regulation through the arrangement of the valve core, the slider and the flow regulating plate. It has a compact structure, a small size and a low manufacturing cost. It can be quickly opened and closed by pulling the valve stem and the flow can be adjusted by rotating the valve stem. It is easy to operate and has good practicality.

[0010] In the above-mentioned adjustable beer dispensing faucet, the regulating structure includes a reduced diameter section at the tail, the outer diameter of the reduced diameter section is smaller than the outer diameter of the tail, the end of the flow regulating plate facing the valve core side has a plurality of opening grooves evenly distributed in the circumference and connected to the liquid passage hole, and the connection between the valve core and the tail is adapted to the liquid passage hole. A liquid passage gap is formed between the reduced diameter section and the liquid passage hole, and the opening groove is connected to the liquid passage gap. When the tail is axially displaced, the length of the tail extending out of the liquid passage hole will be changed to adjust the flow of beer entering the liquid passage gap. The flow of beer entering the liquid passage channel is adjusted, and the liquid flow is adjusted synchronously; the connection between the valve core and the tail is adapted to the liquid passage hole, which plays a guiding and limiting role, ensuring that the axial displacement of the valve core is stable, and the opening groove allows smooth liquid passage.

[0011] As another case, in the above-mentioned adjustable beer dispensing faucet, the regulating structure includes a plurality of liquid-passing grooves uniformly distributed in the circumferential direction and axially penetrating the inner wall of the liquid-passing hole, and the tail portion has a flange extending out of the liquid-passing hole and radially protruding outward. When the tail portion is axially displaced, the gap between the flange and the flow regulating plate is changed, thereby adjusting the flow entering the liquid-passing groove, thereby adjusting the liquid outflow.

[0012] In the above-mentioned adjustable beer dispensing faucet, the end of the valve core facing the sealing surface is in a cone shape and an annular sealing gasket is embedded in this end, and the outer wall of the sealing gasket and the outer wall of the end of the valve core facing the sealing surface together form an arc surface. When the sealing gasket is sealed to the sealing surface, the sealing effect is good, and the end of the valve core facing the sealing surface is in a cone shape and an arc surface, which guides the beer entering the liquid outlet channel, reduces the impact of beer, reduces the amount of bubbles in the beer flowing out of the liquid outlet channel, and ensures the original taste of the beer.

[0013] In the above-mentioned adjustable beer dispensing faucet, the middle part of the valve stem has a spherical part, the valve body has a receiving part for receiving the spherical part, the bottom inner wall of the receiving part has a step and supports a sealing ring sealed to the spherical part, the top of the receiving part is provided with a sealing sleeve sealed to the spherical part, the outer wall of the receiving part is threadedly connected with a sealing cover, and the sealing cover abuts against the top of the sealing sleeve. In this way, the valve stem is smoothly moved, the sealing performance at the spherical part is good, no leakage occurs, and the service life is long.

[0014] In the above-mentioned adjustable beer dispensing faucet, the outer end of the valve stem is connected with a columnar handle, and the handle is circumferentially fixedly connected to the outer end of the valve stem. The handle increases the convenience of operation, and the valve stem does not need to be designed to be longer.

[0015] In the above-mentioned adjustable beer dispensing faucet, the valve stem is threadedly connected with a decorative cover, and the lower end of the decorative cover has a covering portion which radially protrudes outward and covers the portion of the valve body where the valve stem passes through.

[0016] In the above-mentioned adjustable beer dispensing faucet, the flow regulating plate has a shoulder that protrudes radially outward and abuts against the step on the inner wall of the valve body, the flow regulating plate is embedded with a sealing ring 1 that is sealed to the inner wall of the valve body on the outer wall inside the shoulder, and the flow regulating plate is embedded with a sealing ring 2 on the outer wall outside the shoulder. In this way, the flow regulating plate is easy to install, the sealing ring 1 ensures the sealing between the flow regulating plate and the valve body, and the sealing ring 2 ensures the sealing after the valve body is connected to the beer outlet pipe.

[0017] In the above-mentioned adjustable beer dispensing faucet, the valve body comprises a threaded beer spout, an O-ring is provided between the beer spout and the valve body, and the inner cavity of the beer spout is a liquid outlet channel. In this way, the valve body is easy to manufacture and has a low manufacturing cost.

[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0024] like Figure 1 , Figure 2 and Figure 3As shown in the figure, the adjustable faucet for beer distribution includes a valve stem 1 and a valve body 2. A liquid passing channel 3 and a liquid outlet channel 4 communicating with the liquid passing channel 3 are provided inside the valve body 2. A valve core 5 is arranged axially along the liquid passing channel 3 inside the valve body 2. The inner end of the valve stem 1 is inserted into a mating hole 6 of the valve core 5, and the outer end of the valve stem 1 extends out of the valve body 2. A sealing surface 7 is provided inside the valve body 2 to seal the end of the valve core 5 close to the liquid outlet channel 4 to separate the liquid passing channel 3 and the liquid outlet channel 4. A flow rate regulating plate 8 is provided in the liquid passing channel 3 of the valve body 2. The flow rate regulating plate 8 has a liquid passing hole axially penetrating through it. The valve core 5 has a rod-shaped tail 51 extending into the liquid passing hole. The inner end of the valve stem 1 is threadedly connected with a slider 9 located in the mating hole 6. The slider 9 is circumferentially limited in the mating hole 6, and the outer surfaces of both ends of the slider 9 symmetrically arranged axially along the liquid passing channel 3 are spherical surfaces. In actual manufacturing, the spherical surface can be an arc surface. The hole wall of the mating hole 6 has arc surfaces for the spherical surfaces at both ends of the slider 9 to abut against. In this embodiment, the other two side surfaces of the slider 9 are flat surfaces, and the mating hole 6 has two inner walls that are flat and fit the two side surfaces of the slider 9, so as to realize the circumferential limitation of the slider 9 and the mating hole 6. An adjusting structure is provided between the tail 51 and the flow rate regulating plate 8, which can change the liquid passing flow rate after the axial displacement of the tail 51.

[0025] To elaborate further, in this embodiment, the adjusting structure includes a reduced-diameter section 52 of the tail 51. The outer diameter of the reduced-diameter section 52 is smaller than the outer diameter of the tail 51. The end of the flow rate regulating plate 8 facing the valve core 5 has a number of open slots 81 circumferentially distributed and communicating with the liquid passing hole. In this embodiment, there are two open slots 81. The connection part between the valve core 5 and the tail 51 is adapted to be in the liquid passing hole.

[0026] The end of the valve core 5 facing the sealing surface 7 is conical, and a ring-shaped sealing gasket 10 is embedded at this end. The outer wall of the sealing gasket 10 and the outer wall of the end of the valve core 5 facing the sealing surface 7 together form an arc surface. The middle part of the valve stem 1 has a spherical part 11. The valve body 2 has a receiving part for accommodating the spherical part 11. The bottom inner wall of the receiving part has a step and supports a sealing ring 12 that seals the spherical part 11. A sealing sleeve 13 that seals the spherical part 11 is provided at the top of the receiving part. The outer wall of the receiving part is threadedly connected with a cover 14, and the cover 14 abuts against the top of the sealing sleeve 13.

[0027] The outer end of the valve stem 1 is connected to a columnar handle 15, which is circumferentially fixed to the outer end of the valve stem 1. In this embodiment, the outer end of the valve stem 1 has cutting surfaces on both sides, and the blind hole of the handle 15 is adapted to the outer end of the valve stem 1, so as to achieve circumferential fixed connection between the handle 15 and the outer end of the valve stem 1. In actual manufacturing, the handle 15 and the valve stem 1 can also be passed through a screw or a pin to make the two circumferentially fixed. The valve stem 1 is threadedly connected to a decorative cover 16, and the lower end of the decorative cover 16 has a cover portion 161 that radially protrudes outward and covers the valve body 2 where the valve stem 1 passes through. The decorative cover 16 not only serves as a decoration, but also prevents impurities from entering the valve stem 1 where it passes through the valve body 2. In order to limit the axial position, the valve stem 1 has a shoulder that radially protrudes outward and is abutted against the inner wall step of the decorative cover 16.

[0028] The flow regulating plate 8 has a shoulder 82 which protrudes radially outward and abuts against a step on the inner wall of the valve body 2. A sealing ring 17 which is sealed to the inner wall of the valve body 2 is embedded in the outer wall of the flow regulating plate 8 on the inner side of the shoulder 82. A sealing ring 2 18 is embedded in the outer wall of the flow regulating plate 8 on the outer side of the shoulder 82. The valve body 2 includes a wine outlet nozzle 19 which is threadedly connected. An O-ring 20 is provided between the wine outlet nozzle 19 and the valve body 2. The inner cavity of the wine outlet nozzle 19 is a liquid outlet channel 4.

[0029] When the adjustable beer dispensing faucet is closed, the sealing gasket 10 on the valve core 5 is sealed to the sealing surface 7, separating the liquid passage 3 from the liquid outlet channel 4, and the liquid outlet channel 4 cannot discharge liquid; when liquid needs to be discharged for the first time, the handle 15 is pulled toward the liquid outlet channel 4, and the handle 15 drives the valve stem 1 to swing through an angle with the spherical portion 11 as the center, and the slider 9 at the inner end of the valve stem 1 contacts the matching hole 6 of the valve core 5, so that the valve core 5 and the sealing gasket 10 are away from the sealing surface 7, and the liquid passage 3 and the liquid outlet channel 4 are connected. At this time, turning the handle 15 can drive the valve stem 1 to rotate, and the slider 9 is displaced obliquely downward at the inner end of the valve stem 1. Because the slider 9 and the valve core 5 are limited circumferentially, and the tail 51 extends into the liquid passage hole again, the horizontal force generated by the slider 9 will drive the valve core 5 and the tail 51 to axially displace along the liquid passage 3, so that the length of the tail 51 extending out of the liquid passage hole becomes longer, and enters the reduced diameter section 52 and The beer flow in the liquid gap formed between the liquid holes increases, and the open groove 81 allows the beer to smoothly enter the liquid passage 3. At this time, the handle 15 is rotated in the opposite direction, so that the slider 9 is displaced obliquely upward, and the valve core 5 and the tail 51 are displaced toward the liquid outlet channel 4, thereby reducing the beer flow entering the liquid outlet channel 3, and the beer flow is easy to adjust; after the liquid is discharged, the handle 15 is pulled again to reset the valve core 5 and the tail 51, and the sealing gasket 10 is re-sealed on the sealing surface 7, and the beer separation adjustable faucet is closed; after the first use, the adjustment of the liquid outlet flow has been completed, so for the next use, the handle 15 is directly pulled to drive the valve core 5 to seal or move away from the sealing surface 7, and the opening and closing of the beer distribution adjustable faucet is completed. In subsequent use, if the liquid outlet flow needs to be adjusted again, the handle 15 is pulled to move the valve core 5 away from the sealing surface 7, and then the handle 15 is turned to adjust it again, which is easy to operate.
