Description

  The present invention relates to an effervescent beverage and an effervescent beverage pouring valve for pouring foam generated from the effervescent beverage, and more particularly, for example, provided in a beverage dispenser and the like, and particularly an effervescent beverage such as draft beer. The present invention relates to an effervescent beverage dispensing valve for producing creamy foam when dispensing the beverage.

  In general, as an effervescent beverage dispenser for providing effervescent beverages such as draft beer and sparkling liquor, the one shown in FIG. 18 is known. FIG. 18 is an explanatory view showing a beverage system of the sparkling beverage dispenser. In the following, for convenience of explanation, the sparkling beverage dispenser will be described as a draft beer dispenser.

  In FIG. 18, the draft beer dispenser 1 is connected to the barrel container 3 via the beer hose 2, and the barrel container 3 contains draft beer. The draft beer accommodated in the barrel container 3 is sent to the draft beer dispenser 1 via the supply head 3 a and the beer hose 2 by adding carbon dioxide gas from the carbon dioxide cylinder 4 through the pressure reducing valve 5 and the gas hose 6. The draft beer delivered to the draft beer dispenser 1 is cooled by a cooling coil (not shown) provided in the draft beer dispenser 1 to be in an appropriate temperature state, and has a foaming property disposed on the bend stage of the draft beer dispenser 1. It is led to draft beer pouring valve 7 as a beverage pouring valve. Then, for example, when a drinking container 8 such as a mug or a paper cup is set as shown in the drawing and the operation lever 7a of the draft beer pouring valve 7 is operated, draft beer is poured from the draft beer pouring valve 7 to the drinking container 8. Provided.

  FIG. 19 is a cross-sectional side view showing a configuration of a conventional draft beer pouring valve (foamable beverage pouring valve). In the conventional draft beer dispensing valve 100, when the operation lever 101 is swung downward, draft beer supplied from the draft beer dispenser 1 (see FIG. 18) is poured from the beverage dispensing nozzle 102 through a predetermined passage. Is issued. On the other hand, when the operation lever 101 is swung upward, the draft beer supplied from the draft beer dispenser 1 passes through the hollow portion 104 provided in the valve body 103 and passes through the narrow hole 105 having a smaller diameter than the hollow portion 104. It ejects at high speed and collides with the bubble generating piece 106. Thereby, the draft beer becomes creamy foam and is poured out from the foam pouring nozzle 107 (see, for example, Patent Document 1).

JP 2001-2195A

  In the conventional sparkling beverage dispensing valve, draft beer is ejected from the throttle hole 105 at a high speed and collides with the foam generating piece 106 when generating creamy foam. However, if there is momentum in the draft beer ejection from the throttle hole 105, the foam generated by colliding with the foam generating piece 106 is vigorously poured out from the foam dispensing nozzle 107, and poured into the drinking container 8 first. It is poured into the liquid level of draft beer. For this reason, since the foam poured into the drinking container 8 collides with the liquid level of the draft beer and generates new foam, more foam than necessary is brought into the drinking container 8. On the contrary, if there is no momentum in the ejection of draft beer from the throttle hole 105, the foam generated by colliding with the foam generating piece 106 does not become creamy foam (good quality foam with fine bubbles), but in the drinking container 8 Can not last long.

  By the way, the momentum and quality of draft beer that collides with the foam generating piece 106 (such as the size of bubbles) are substantially determined by the diameter of the throttle hole 105 and the distance between the throttle hole 105 and the foam generating piece 106. It varies depending on the type of carbon dioxide (carbon dioxide content), draft beer temperature or carbon dioxide gas pressure, and greatly affects the quality of creamy foam.

  In view of the above circumstances, an object of the present invention is to provide a sparkling beverage dispensing valve capable of adjusting the momentum and the quality of foam to be generated while generating creamy foam.

In order to achieve the above object, a sparkling beverage pouring valve according to claim 1 of the present invention includes a beverage pouring means for pouring the supplied sparkling beverage and foam from the supplied sparkling beverage. In the sparkling beverage pouring valve having foam generating and pouring means for pouring and foaming the foam, the foam generating and pouring means includes a throttle hole for ejecting the supplied sparkling beverage, and the throttle hole There is provided form a conductive path for guiding the ejected foamable beverage from the Shiboana a inner wall surface facing the recess at a site facing the Oite the Shiboana the inner wall surface of the conductive path A colliding portion for causing the sparkling beverage ejected from the constricted hole to collide with the bottom portion of the recess, and the recess in the colliding portion has a bottom portion of the sparkling beverage ejected from the constricting hole. It is composed of a surface orthogonal to the ejection direction, and the sparkling beverage ejected from the throttle hole is formed in the recess. Generating foam by striking the parts, and wherein the impinging the jetted effervescent beverage bubbles leaving the conductive path along the inner wall of said recess from said Shiboana.

The sparkling beverage pouring valve according to claim 2 of the present invention generates a foam from the beverage pouring means for pouring the supplied sparkling beverage and the supplied sparkling beverage, and dispenses the foam. In the sparkling beverage pouring valve having foam generating and pouring means, the foam generating and pouring means has a throttle hole for ejecting the supplied sparkling beverage and an inner wall surface facing the throttle hole. a conductive path for guiding the foaming beverage ejected from the Shiboana, an insertion hole provided at a portion facing the Oite the Shiboana the inner wall surface of the conductive paths, so as to be movable in the extending direction of the insertion hole A collision part inserted into the insertion hole, and a collision part that generates foam by colliding a sparkling beverage ejected from the throttle hole with a tip part of the collision element, and the collision part The tip of the collider is in the direction of ejection of the sparkling beverage ejected from the throttle hole. And a receiving position where the tip end is received in the insertion hole to form a recess, and the tip protrudes from the insertion hole and is located in the conduction path. It is configured to be movable to a protruding position formed .

  According to a third aspect of the present invention, there is provided the sparkling beverage dispensing valve according to the first or second aspect, wherein the collision portion has an elastic member that is elastically deformed by the momentum of the sparkling beverage injected from the throttle hole. It is characterized by being provided.

  In the sparkling beverage dispensing valve according to the present invention, the sparkling beverage ejected from the throttle hole collides with the bottom of the recess. The sparkling beverage that collides with the bottom of the recess becomes foam and exits from the recess to the conduction path. At this time, since the sparkling beverage is continuously ejected from the constricted hole into the recess, the foam coming out of the concavity into the conduction path and the sparkling beverage ejected from the constricting hole collide with each other. As a result, the creamy foam generated by colliding with the bottom of the recess is counterbalanced by the sparkling beverage continuously ejected from the throttle hole, so that the sparkling beverage having a momentum at a high speed can be obtained from the throttle hole. Even if ejected, creamy foam can be poured out by suppressing the momentum of the foam generated or changing the quality of the foam.

  In the sparkling beverage dispensing valve according to the present invention, when the collision part is adjusted to the position where the concave part is formed, the creamy foam generated by colliding with the bottom part of the concave part is continuously ejected from the throttle hole. Since the momentum is offset by the sparkling beverage, even if a sparkling beverage with a high momentum is ejected from the throttle hole, the momentum of the generated foam is suppressed, or the quality of the foam is changed and the creamy foam is poured out. can do. On the other hand, when the collision part is adjusted to a convex position, the sparkling beverage spouted from the throttle hole does not immediately collide with the collision part and the momentum does not weaken. Even if squirts, it is possible to pour out creamy foam by changing the quality of the foam without weakening the generated foam.

  In addition, since the impact member is provided with an elastic member that is elastically deformed by the momentum of the sparkling beverage injected from the throttle hole, the momentum of the sparkling beverage ejected from the throttle hole is received and the creamy is always suitable. Bubbles can be generated. Particularly, the elastic member can receive the momentum of the sparkling beverage when the momentum of the sparkling beverage ejected from the throttle hole suddenly and strongly changes.

  Moreover, since the collision part has a hollow part in the site | part which receives the sparkling beverage injected from the throttle hole, the sparkling beverage injected from the throttle hole is made to collide with a hollow part, The said sparkling beverage Can be adjusted to reduce the momentum or change the quality of the foam.

  In addition, since the collision part has a protruding part at a part that receives the sparkling beverage injected from the throttle hole, the sparkling beverage injected from the throttle hole is caused to collide with the hollow part, and the sparkling beverage It can be adjusted to change the quality of the foam without weakening the momentum.

The valve body 12 includes a valve chamber 121, a valve shaft guide 122, and a beverage dispensing nozzle 123. The valve chamber 121 is located at a position continuous with the large diameter portion in the outflow portion 112 of the valve joint 11. The valve chamber 121 is formed with a valve seat 121a having a narrow inner diameter. The valve shaft guide portion 122 is formed to extend forward from the valve chamber 121 via the valve seat 121a. The beverage pouring nozzle 123 (beverage pouring portion) is for pouring draft beer as an effervescent beverage, is connected to the front side from the valve chamber 121 via the valve seat 121a, and from the valve shaft guide portion 122. It is branched and drawn downward to form an opening.

  The valve body 20 is accommodated in the valve chamber 121 of the valve body 12. The valve body 20 includes a valve shaft 21, a beverage valve holder 22, a valve body cap 23, and a foam valve holder 24.

  The valve shaft 21 extends from the valve chamber 121 to the valve shaft guide portion 122 in a longitudinal shape, and a hollow portion 211 communicating in the longitudinal direction is provided therein. The hollow portion 211 forms a bubble generation passage 211a described later. A throttle hole 213 in which the inner diameter of the hollow part 211 is narrowed to a small diameter is provided at the front end of the valve shaft 21. An opening 21 a that opens with the inner diameter of the hollow portion 211 is provided at the rear end of the valve shaft 21. Further, the valve shaft 21 is formed with a flange 214 at a predetermined location in the intermediate region on the outer periphery thereof.

  The beverage valve holder 22 is inserted through the outer periphery of the valve shaft 21 at a position behind the flange 214. The beverage valve holder 22 is slidably provided along the longitudinal direction of the valve shaft 21 and engages with the flange 214 when sliding toward the front of the valve shaft 21. Further, the beverage valve holder 22 is formed in a cylindrical shape, the inner peripheral wall on the front side thereof is slid on the outer periphery of the valve shaft 21, and the other inner peripheral wall on the rear side is separated from the outer periphery of the valve shaft 21. Formed. In addition, an O-ring 25 and a spring seat 26 are fitted into a portion of the inner peripheral wall of the beverage valve holder 22 and the outer periphery of the valve shaft 21 so that the beverage valve holder 22 and the valve shaft 21 are separated from each other. The space is liquid-tight. Further, the beverage valve holder 22 holds an annular beverage valve 221 on the front end side. The beverage valve 221 is in contact with the valve seat 121a of the valve chamber 121 in the state shown in FIGS.

  The valve body cap 23 has a conical portion 231 having a substantially conical shape on the rear side, and a cylindrical portion 232 having a cylindrical shape on the front side. That is, the valve cap 23 has a recess 233 that opens forward by the bottom of the conical portion 231 and the inner diameter of the cylindrical portion 232. A plurality of beverage introduction holes 234 are formed on the peripheral wall surface of the cylindrical portion 232 of the valve cap 23. The valve body cap 23 is liquid-tightly coupled to each other by screwing the cylindrical portion 232 (opening portion of the recess 233) to the outer peripheral wall on the rear side of the beverage valve holder 22.

  The foam valve holder 24 is fixed to the outer periphery of the rear end of the valve shaft 21 at a position behind the beverage valve holder 22. The foam valve holder 24 holds an annular foam valve 241 on the rear end side. Between the foam valve holder 24 and the beverage valve holder 22, more specifically, the front end portion of the foam valve holder 24 and the cylindrical interior of the beverage valve holder 22, and the spring seat 26 is inserted. A compression coil spring 27 wound around the valve shaft 21 is interposed between the portions. For example, as shown in FIGS. 1 and 3, the compression coil spring 27 presses the beverage valve holder 22 toward the flange 214, and the foam valve 241 moves to the bottom of the recess 233 of the valve cap 23. Press on the part. As a result, the opening 21a at the rear end of the valve shaft 21 is closed.

  By the way, the slide part 30 is arrange | positioned by the valve-shaft guide part 122 of the valve main body 12 so that a movement in the front-back direction is possible. The slide portion 30 is held by the front end portion of the valve shaft 21. An operation lever 40 is connected to the slide portion 30. More specifically, a spherical coupling portion 41 formed at the tip of the operation lever 40 is inserted through and connected to a fitting groove 30 a formed in the slide portion 30. The operation lever 40 is pivotally supported by a spherical seat 128 having a spherical fulcrum portion 42 formed on the valve body 12, and is attached so as to be swingable by a nut 129 via a spherical ring 128a and a packing 128b. . That is, when the operation lever 40 is tilted in the front-rear direction, the slide part 30 moves the valve shaft guide part 122 of the valve body 12 in the front-rear direction.

  As shown in FIG. 2, a conductive path 31 that communicates with a throttle hole 213 in the valve shaft 21 is formed in the slide portion 30. This conduction path 31 is opened in a direction (right direction in FIG. 2) orthogonal to the extending direction of the valve shaft 21 (hollow part 211). The conduction path 31 has an inner wall surface facing the throttle hole 213. A collision portion 50 is provided on the inner wall surface facing the throttle hole 213. The collision portion 50 is provided with a recess 51 with respect to the inner wall surface of the conduction path 31 so that draft beer ejected from the throttle hole 213 collides with the bottom 51 a of the recess 51. As shown in FIGS. 1 and 3, an air introduction hole 32 communicating with the conduction path 31 is formed in the slide portion 30 in the upward direction.

  Further, the valve body 12 has a projecting opening as shown in FIG. 2 at a location corresponding to the conduction path 31, that is, a location corresponding to a moving region where the conduction path 31 exists as the slide portion 30 moves in the front-rear direction. A portion 124 is formed. The protruding opening 124 protrudes to the right of the draft beer pouring valve 10 in FIG. The protruding opening 124 is provided with a foam dispensing nozzle (foam dispensing section) 127. The foam pouring nozzle 127 is fitted into the projecting opening 124 so as to cover the projecting opening 124, has a substantially L shape, and is provided to open downward like the beverage pouring nozzle 123. is there. This foam pouring nozzle 127 is made of an elastic material such as silicone rubber.

  Further, in the upper part of the valve body 12, when the slide part 30 is in the state as shown in FIGS. 1 and 3, the first air hole 125 communicating the air introduction hole 32 of the slide part 30 to the outside of the valve body 12. Is formed. Further, when the slide portion 30 is in the state shown in FIGS. 1 and 3, the beverage dispensing nozzle 123 is communicated to the outside of the valve body 12 via the valve shaft guide portion 122. A second air hole 126 is formed.

  Next, operation | movement of the draft beer extraction valve | bulb 10 comprised as mentioned above is demonstrated. As shown in FIGS. 1 and 3, the draft beer pouring valve 10 is configured such that when the operation lever 40 is almost upright, the beverage valve 221 of the valve body 20 contacts the valve seat 121 a of the valve chamber 121. The chamber 121 is closed. In the draft beer dispensing valve 10, when the operation lever 40 is substantially upright, the foam valve 241 is pressed against the bottom portion of the recess 233 of the valve cap 23 by the urging force of the compression coil spring 27. The opening 21a at the rear end of 21 is closed. Therefore, the draft beer dispensing valve 10 is in a closed state so that draft beer guided from the draft beer dispenser 1 does not flow. This state is generally called a neutral state (standby state).

  As shown in FIGS. 4 and 5, when the operation lever 40 is swung manually or automatically forward (leftward in FIGS. 4 and 5), the draft beer pouring valve 10 has the slide portion 30 at the rear. (Move to the right in FIGS. 4 and 5). Thereby, the communication state between the air introduction hole 32 of the slide portion 30 and the first air hole 125 of the valve body 12 is blocked. At the same time, the communication state between the second air hole 126 of the valve body 12 and the beverage dispensing nozzle 123 is blocked.

  Due to the backward movement of the slide part 30, the valve body 20 also moves backward via the valve shaft 21. As a result, the abutment between the beverage valve 221 and the valve seat 121a is released, and the beverage is opened, and draft beer from the draft beer dispenser 1 flows along the arrows in FIGS. Draft beer is poured out from. At this time, since the foam valve 241 is pressed by the urging force of the compression coil spring 27 to close the opening 21a of the valve shaft 21, draft beer does not flow into the hollow portion 211 (foam generation passage 211a). This state is called a liquid dispensing state. Thus, the slide part 30, the valve shaft 21, the beverage valve 221 and the valve chamber 121 mainly constitute draft beer pouring means (foamable beverage pouring means).

  Next, when the operation lever 40 is manually or automatically returned to the neutral position as shown in FIGS. 1 and 3 and the draft beer pouring valve 10 returns from the liquid pouring state to the neutral state, the beverage valve 221 is again moved to the valve seat. Closes in contact with 121a. Thereby, the extraction of draft beer is completed. At this time, a rapid pressure increase occurs in the valve chamber 121 due to a water hammer effect caused by the flow of draft beer. However, the opening 21 a of the valve shaft 21 is closed by the biasing force of the compression coil spring 27. Furthermore, in order for draft beer to communicate with the position of the opening 21 a of the valve shaft 21, it is necessary to pass through the beverage introduction hole 234 on the peripheral wall surface of the valve body cap 23. Accordingly, the water dynamic pressure due to the water hammer action does not directly act on the opening 21 a of the valve shaft 21. For this reason, it does not receive the influence of a water hammer effect, and the bubble generation | occurrence | production accompanying the stop of the extraction of draft beer does not arise.

  Next, as shown in FIGS. 6 and 7, when the operating lever 40 is swung manually or automatically backward (rightward in FIGS. 6 and 7), the draft beer dispensing valve 10 has the slide portion 30 as shown in FIG. It moves forward (to the left in FIGS. 6 and 7). Thereby, the communication state between the air introduction hole 32 of the slide portion 30 and the first air hole 125 of the valve body 12 is blocked. On the other hand, the second air hole 126 of the valve body 12 and the beverage dispensing nozzle 123 are in communication with each other via the valve shaft guide portion 122.

  As the slide portion 30 moves forward, the valve shaft 21 also moves forward. At this time, since the beverage valve 221 of the valve body 20 contacts the valve seat 121a of the valve chamber 121 to close the valve chamber 121, only the valve shaft 21 moves forward against the urging force of the compression coil spring 27. Moving. For this reason, the contact state between the foam valve 241 at the rear end of the valve shaft 21 and the bottom portion of the recess 233 of the valve cap 23 is released, and the opening 21a of the valve shaft 21 is opened. The beverage valve 221 holds a closed state in contact with the valve seat 121a by the urging force of the compression coil spring 27. Thereby, the draft beer from the draft beer dispenser 1 passes through the inflow portion 111 and the outflow portion 112 of the valve joint 11 as shown by the arrows in FIGS. 6 and 7, passes through the beverage introduction hole 234, and is hollow in the valve shaft 21. It flows through the section 211 (the bubble generation passage 211a). The draft beer that has flowed through the foam-generating passage 211a is ejected at high speed through the throttle hole 213 and into the conduction passage 31. Further, the draft beer ejected from the throttle hole 213 collides with the bottom 51 a of the recess 51 as the collision part 50. Thereby, a creamy bubble with fine bubbles is generated, and this bubble is poured out from the bubble dispensing nozzle 127 as indicated by an arrow in FIG. This state is called a bubble extraction state. Thus, mainly the slide part 30, the valve shaft 21, the valve body cap 23, the hollow part 211 (foam generation passage 211a), the throttle hole 213, the conduction path 31, and the collision part 50 constitute the foam generation and extraction means. To do.

  Finally, when the operation lever 40 is manually or automatically returned to the neutral position, the opening 21a of the valve shaft 21 is closed by the urging force of the compression coil spring 27, so that the foam dispensing is finished.

  Note that when the draft beer or foam is dispensed and the draft beer dispensing valve 10 is in a neutral state, the first air hole 125, the air introduction hole 32, the conduction path 31, and the foam dispensing nozzle 127 communicate with each other. Outside air communicates with the foam dispensing nozzle 127. This prevents bubbles from adhering to the inner wall surface of the foam dispensing nozzle 127 and remaining. In addition, when the draft beer dispensing valve 10 is in a neutral state, the second air hole 126, the valve shaft guide 122, and the beverage dispensing nozzle 123 are communicated with each other so that the outside air communicates with the beverage dispensing nozzle 123. Thereby, draft beer does not adhere and remain on the inner wall surface of the beverage pouring nozzle 123.

  Here, the production | generation of the foam by a foam production | generation extraction means is explained in full detail. The recess 51 of the collision portion 50 is provided on the inner wall surface of the conduction path 31 facing the throttle hole 213. For this reason, draft beer ejected from the throttle hole 213 collides with the bottom 51 a of the recess 51. The draft beer that has collided with the bottom 51 a of the recess 51 becomes foam and goes out to the conduction path 31 along the inner wall of the recess 51. At this time, draft beer is continuously ejected from the throttle hole 213 into the recess 51. That is, the foam coming out from the recess 51 to the conduction path 31 and the draft beer ejected from the throttle hole 213 collide with each other. Accordingly, the creamy foam generated by colliding with the bottom 51a of the recess 51 is canceled out by the draft beer continuously ejected from the throttle hole 213, so that the draft beer with momentum is ejected from the throttle hole 213 at high speed. Even if it is done, the generated foam is suppressed from the foam pouring nozzle 127 with reduced momentum. As a result, it is possible to prevent the foam poured into the drinking container 8 (see FIG. 18) from colliding with the liquid level of the draft beer previously extracted and generating new foam.

  In addition, the foam quality (for example, the size of the bubbles) changes when the foam exiting from the recess 51 to the conduction path 31 and the draft beer ejected from the throttle hole 213 collide with each other. The quality of foam varies depending on the type of draft beer (carbon dioxide content), draft beer temperature or carbon dioxide gas pressure, etc. The foam quality is changed so that creamy foam is obtained according to these factors. It is possible.

  FIG. 9 is a main part enlarged view showing Example 2 of the sparkling beverage pouring valve according to the present invention, and FIG. 10 is a main part enlarged view showing another form of the sparkling beverage pouring valve shown in FIG. . In the second embodiment described below, the same parts as those in the above-described first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  The draft beer pouring valve 10 in the second embodiment is different from the first embodiment in the collision portion. As shown in FIGS. 9 and 10, the collision portion 60 of the second embodiment is provided on the inner wall surface of the conduction path 31 facing the throttle hole 213. The collision unit 60 includes an insertion hole 61 provided in the inner wall surface of the conduction path 31, a collision element 62 inserted through the insertion hole 61, and a moving unit 63 that moves the collision element 62 with respect to the insertion hole 61. Consists of. The insertion hole 61 extends from the inner wall surface of the conduction path 31 forward (leftward in FIGS. 9 and 10) and is opened. The collision element 62 is inserted in such a manner that the tip 62 a faces the throttle hole 213 so as to be slidable in the extending direction of the insertion hole 61. The moving part 63 holds the base end 62b of the collider 62 and is attached to the front end side of the slide part 30 so as to be movable in the front-rear direction (left-right direction in FIGS. 9 and 10). Specifically, the moving part 63 has a male screw part 63 a on a cylindrical peripheral surface, and the male screw part 63 a is screwed to a female screw part 301 provided on the front end side of the slide part 30. A tool hole 63b for engaging a tool is provided at the front end of the moving part 63. That is, by engaging the tool with the tool hole 63b and rotating the moving portion 63, the moving portion 63 moves in the front-rear direction with respect to the slide portion 30, and the collider 62 moves along the insertion hole 61 with this movement. Move forward and backward. As a result, the colliding element 62 has a receiving position where the tip 62a is received in the insertion hole 61 as shown in FIG. 9 and a recess, and the tip 62a protrudes from the insertion hole 61 as shown in FIG. It moves to the protruding position which is located in 31 and makes a convex.

  The draft beer dispensing valve 10 according to the second embodiment configured as described above has a tip of the collider 62 in which draft beer ejected from the throttle hole 213 is accommodated in the insertion hole 61 when the foam is being dispensed in the form shown in FIG. Collide with 62a. The draft beer that has collided with the tip 62 a of the collider 62 becomes foam and goes out to the conduction path 31 along the inner wall of the insertion hole 61. At this time, draft beer is continuously ejected into the insertion hole 61 from the throttle hole 213. That is, the foam coming out from the insertion hole 61 to the conduction path 31 and the draft beer ejected from the throttle hole 213 collide with each other. Accordingly, the creamy foam generated by colliding with the tip 62a of the collider 62 is canceled out by the draft beer continuously ejected from the throttle hole 213, so that the draft beer with a momentum is ejected from the throttle hole 213 at high speed. Even if it is done, the generated foam is suppressed from the foam pouring nozzle 127 with reduced momentum. As a result, it is possible to prevent the foam poured into the drinking container 8 (see FIG. 18) from colliding with the liquid level of the draft beer previously extracted and generating new foam.

  On the other hand, when the draft beer dispensing valve 10 in Example 2 is in the foam dispensing state in the form shown in FIG. 10, draft beer ejected from the throttle hole 213 collides with the tip 62 a of the collider 62 projecting from the insertion hole 61. . The draft beer that has collided with the tip 62a of the collider 62 becomes foam and passes through the conduction path 31 and is poured out from the foam dispensing nozzle 127. That is, the draft beer ejected from the throttle hole 213 immediately collides with the tip 62a of the collider 62, so that the generated creamy foam is poured out from the foam dispensing nozzle 127 without weakening the momentum. As a result, even if draft beer with a weak momentum is ejected from the throttle hole 213, it becomes possible to generate creamy foam.

  As described above, the draft beer dispensing valve 10 according to the second embodiment described above moves drafting beer from the throttle hole 213 by moving the collider 62 between the accommodation position and the protruding position with respect to the insertion hole 61. Depending on the momentum, a suitable creamy foam can be produced. The momentum of draft beer ejected from the throttle 213 changes depending on the type of draft beer (carbon dioxide content), draft beer temperature or carbon dioxide gas pressure, etc., and creamy foam is generated depending on these factors. It is possible to obtain.

  Further, by moving the collider 62 between the accommodation position and the protruding position with respect to the insertion hole 61, the quality of the bubbles (for example, the size of the bubbles) changes. Foam quality varies depending on the type of draft beer (carbon dioxide content), draft beer temperature or carbon dioxide gas pressure, etc. The foam quality is adjusted to obtain creamy foam according to these factors. Is possible.

  By the way, in the draft beer pouring valve in Example 2 described above, the tip 62a of the collision element 62 is abutted against the throttle hole 213 by the configuration in which the position of the collision element 62 can be changed, and the distance between the collision element 62 and the restriction hole 213 is increased. It is possible to eliminate it. Thereby, while stopping the production | generation of foam, the situation where draft beer before ejecting from the throttle hole 213 touches external air is prevented. As a result, it becomes possible to suppress deterioration of parts due to draft beer sticking or the like.

  FIG. 11 is an enlarged view of the main part showing Example 3 of the sparkling beverage pouring valve according to the present invention, and FIG. 12 is an enlarged view of the main part showing another form of the sparkling beverage pouring valve shown in FIG. . In the third embodiment described below, the same parts as those in the above-described first embodiment are denoted by the same reference numerals and the description thereof is omitted.

  The draft beer pouring valve 10 in the third embodiment is different from the first embodiment in the collision portion. As shown in FIGS. 11 and 12, the collision portion 70 according to the third embodiment is provided on the inner wall surface of the conduction path 31 facing the throttle hole 213. The collision part 70 is an insertion hole 71 provided on the inner wall surface of the conduction path 31, a collision element 72 inserted through the insertion hole 71, and a compression that urges the collision element 72 to a position inserted through the insertion hole 71. It comprises a spring 73 (elastic member) and an adjustment unit 74 that adjusts the urging force of the compression spring 73. The insertion hole 71 extends from the inner wall surface of the conduction path 31 to the front (leftward in FIGS. 11 and 12). The collision element 72 is inserted in such a manner that the distal end 72 a faces the throttle hole 213 so as to be slidable in the extending direction of the insertion hole 71. A flange 72 b that engages with the front opening edge of the insertion hole 71 is provided at the base end of the collision piece 72. By preparing the collision pieces 72 having different lengths, as shown in FIG. 11, the distal end 72a is accommodated in the insertion hole 71 to form a recess, and the distal end 72a as shown in FIG. Projecting from the insertion hole 71 and located in the conduction path 31 to obtain a projecting position. The compression spring 73 is provided in the accommodation recess 302 provided on the front end side of the slide portion 30 and communicating with the insertion hole 71, and abuts on the flange 72 b of the collision piece 72. The adjusting portion 74 has a male threaded portion 74a on a cylindrical peripheral surface, and the male threaded portion 74a is screwed to a female threaded portion 303 provided on the inner peripheral surface of the accommodating recess 302 of the slide portion 30 to compress the spring. 73 abuts. A tool hole 74b for engaging a tool is provided at the front end of the adjusting portion 74. In other words, by engaging the tool in the tool hole 74b and rotating the adjusting portion 74, the adjusting portion 74 moves in the front-rear direction with respect to the slide portion 30, and the compression state of the compression spring 73 is changed with this movement. adjust.

  The draft beer dispensing valve 10 according to the third embodiment configured as described above has a tip of the collider 72 in which draft beer ejected from the throttle hole 213 is accommodated in the insertion hole 71 when the foam is being dispensed in the form shown in FIG. Collide with 72a. The draft beer that has collided with the tip 72 a of the collider 72 becomes foam and exits to the conduction path 31 along the inner wall of the insertion hole 71. At this time, draft beer is continuously ejected into the insertion hole 71 from the throttle hole 213. That is, the foam coming out from the insertion hole 71 to the conduction path 31 and the draft beer ejected from the throttle hole 213 collide with each other. Accordingly, the creamy foam generated by colliding with the tip 72a of the collider 72 is canceled out by the draft beer continuously ejected from the throttle hole 213, so that the draft beer with a momentum is ejected from the throttle hole 213 at a high speed. Even if it is done, the generated foam is suppressed from the foam pouring nozzle 127 with reduced momentum. As a result, it is possible to prevent the foam poured into the drinking container 8 (see FIG. 18) from colliding with the liquid level of the draft beer previously extracted and generating new foam. Further, even if draft beer that is vigorous at high speed from the throttle hole 213 collides with the tip 72 a of the collision piece 72, the collision piece 72 is provided via the compression spring 73. It is possible to carry away momentum. In particular, the compression spring 73 is suitable for receiving the momentum of the draft beer when the momentum of the draft beer ejected from the throttle hole 213 suddenly and strongly changes.

  In the draft beer dispensing valve 10 according to the third embodiment, when the foam is being poured out in the form shown in FIG. 12, draft beer ejected from the throttle hole 213 collides with the tip 72 a of the collider 72 projecting from the insertion hole 71. . The draft beer that has collided with the tip 72 a of the collider 72 becomes foam and passes through the conduction path 31 and is poured out from the foam dispensing nozzle 127. That is, the draft beer ejected from the throttle hole 213 immediately collides with the tip 72a of the collider 72, so that the generated creamy foam is poured out from the foam dispensing nozzle 127 without weakening the momentum. As a result, even if draft beer with a weak momentum is ejected from the throttle hole 213, it becomes possible to generate creamy foam. Further, when the momentum of draft beer ejected from the aperture 213 suddenly and strongly changes, since the collision element 72 is provided via the compression spring 73, the momentum of the draft beer can be received by elastic deformation of the compression spring 73. It is.

  As described above, the draft beer dispensing valve 10 according to the third embodiment described above has the momentum of draft beer ejected from the throttle hole 213 by the elastic deformation of the compression spring 73 that biases the collision element 72 to the position where the collider 72 is inserted into the insertion hole 71. It is possible to always flow and produce a suitable creamy foam. The momentum of draft beer ejected from the throttle hole 213 varies depending on the type of draft beer (carbon dioxide content), draft beer temperature or carbon dioxide gas pressure, etc., and general purpose to obtain creamy foam according to these factors It is possible to have sex.
