Description

Injection device for carbonated liquid

technical field

The present invention relates to apparatus for serving carbonated beverages, such as draft beer.

current technology

Figure 26 illustrates a draft beer serving system, i.e. a device for pouring carbonated liquid into cups. In this figure, a high-pressure carbon dioxide gas is charged into a beer keg 24 through a hose 25, through a supply head 24a, a beer hose 26, a cooling container 27, a beer hose 26a and a cap-shaped The connecting piece 22 fixed by the nut 23 injects draft beer into a cup from the injection valve 21 .

27 is a cross-sectional view of a conventional liquid injection valve, in which the liquid is supplied from the connection piece 22 on the right side of the figure and sprayed toward the lower left side of the valve body 31. FIG. The connecting piece 22 is connected with the first side of the valve body 31 through the cap nut 23 and supplies liquid thereto. A valve body 32 includes a seal 32b fixed to its right end; and a thin rod 32a in the middle of the valve body, around which liquid flows. When the rod 33 is turned along P around the circumferential surface 34a of the pressure portion of the compression nut 34, the valve body 32 slides leftward so that the seal 32b closes the passage on the valve seat 31b in a watertight manner. Such a conventional example of reducing the flow variation in the tortuous portion of the valve body passage used to prevent excessive foaming of a carbonated liquid is disclosed in a Japanese patent application titled "Valve Device for Discharging Carbonated Liquid" An example of this is disclosed in 6-100332.

In the beverage injection device, in order to maintain a hygienic state, it is necessary to periodically clean the inside of the tube. In order to be able to clean, a sponge ball must be inserted into the supply head 24a in Fig. 26, and then water pressure is applied to make the sponge slide to clean the dirt in the pipe. Figure 28 shows the configuration of the fill valve when cleaning with a sponge. Remove the compression nut 34, rod 33, cap nut 23 and connector 22, and pull out the valve body 32, then insert the valve body back into the valve body 31. Before cleaning the device with a sponge, the rod 33 must be inserted In the device and fixed by the compression nut 34, the connecting piece 22 must also be fixed by the cap nut 23.

In addition, FIG. 29 shows a cooling water passage in a conventional injection valve. Since it is known that less foam is produced when the valve body is cooled, a cooling water channel 152 is formed through the valve body 151, and the passing portion has been treated to make it watertight before the cooling water flows through the cooling valve body.

In addition, Figure 30 simply illustrates the device for injecting carbonated liquid into a large or small cup, wherein the small or large cup 41 or 42 is placed on a cup having a support point 48 and a fixed support point 47 Rack 46. When a cup is placed on the cup holder 46, a driving mechanism (not shown) rotates the cup holder 46 along the direction R until the supporting point 48 tilts to a specific angle. For a small cup 41a, another drive mechanism (not shown) lifts the small cup 41a a distance L, so that the carbonated liquid can be injected into the cup through a nozzle 43. In order to reduce foam when pouring, the nozzle 43 reaches the inner edge of the cup and is inclined to the cup.

Using this conventional technique, disassembly and assembly of the fill valve during cleaning requires time-consuming and skilled operations. In addition, if the valve body 32 is incorrectly assembled upside down after cleaning (especially if a carbonated liquid such as beer is injected), a large amount of air will remain on the inner upper portion of the valve body 31, which will be trapped after the new injection. Your draft beer will continually produce excessive foam. In addition, it is not easy to disassemble only the valve body in this device.

In addition, according to another conventional example, a valve body is produced with a cooling passage passing through the valve body, thereby requiring the use of complicated processes and increasing costs. And another conventional example has a large gap between the side of the big cup and the spout, so that the foam will overflow.

When the cylindrical arm 106a moves along the direction P from the position shown in the figure, the valve body 102 moves to the right to open the passage, so that the carbonation liquid flows out from the connecting piece 22 side.

Figure 13 is a cross-sectional view showing the device during cleaning with a sponge. When the arm 105 is raised in the U direction, the arm end 105t is placed in the middle position of the positioning spring 109, and the rod 104 is also raised. The position of the arm is maintained in such a way that the flat protrusion 104f of the rod 104 can be inserted into a slot 101a. Therefore, a cap nut 103 , an inner cylinder 101 and a valve body 102 can be moved along the direction S to take out, so that the channel in the valve body 100 can be cleaned with a sponge. In this case, a portion of the groove 101a needs to be used as a stopper for the flat convex portion 104f, and this portion can also be used to prevent the leakage of washing water.

Figure 14 shows that when the arm is further raised from the state shown in Figure 13, the arm end 105t is supported by the lower part of the positioning spring 109, and the flat convex part 104f of the rod 104 is taken out from the inner cylinder 101, thereby breaking away from the valve body 100 parts, such as the valve body 102 and the inner cylinder 101 that have been drawn out in FIG. 13 . In this case, the parts in contact with the liquid can be cleaned more carefully.

FIG. 15 illustrates this embodiment in detail, omitting components already explained in FIG. 12 . As shown in FIG. 15(b), the valve body 100 has three pins 101a arranged at equal intervals, and the cap nut 103 has three deformed "L"-shaped grooves 103a on its side corresponding to the pins 101a. As shown in FIG. 15( a ), an inner cylinder 101 and a spring 65 are installed between the valve body 100 and the cap nut 103 . To place and fix the inner cylinder 101 in the valve body 100, the grooves 103a are fitted with the corresponding pins 101a, and the cap nuts 103 are turned to fix them. The spring 65 applies an appropriate pressure to keep the seal 201 in the inner barrel to prevent liquid leakage.

Example 8: Figure 16 details the invention that makes the Figure 13 embodiment easier to extract. The valve body 102 has a notch at its end, as shown in Figure 16 (b); a groove with a diameter equal to the smaller width of the notch formed in the notch; and one formed in the cap nut 103, A notch with the same shape as the notch at the end of the valve body 102 but with a larger size. Due to the configuration in Figure 15, when the cap nut 103 is turned leftward to disengage it from the pins, the two pins are as shown in Figure 16(c). When taking out along the S direction in Fig. 13, the cap nut 102 pulls the valve body 102, and the valve body 102 pulls the inner cylinder 101, so that they can be taken out at the same time.

Embodiment 9: The structure of the present invention shown in FIG. 17 makes the extraction in FIG. 13 easier. A cam arm 112 is fixed to the rod 104 and is also in contact with a cam 111 fixed to the cap nut 103 by a spring 113 for extending the cam arm 112 and the cylindrical arm 106 above the rod 104 . When the cap nut 103 is turned, since the cam 111 moves, the cam arm 112 and the rod 104 move upward, so that the inner cylinder 101 can be taken out as shown in FIG. 18 . In this case, when the cap nut 103 is taken out, as shown in FIG. 19, sponge cleaning similar to that in FIG. 13 can be performed.

Embodiment 10: A configuration shown in FIG. 20 allows the valve body 100 to be easily taken out from the state shown in FIG. 12 for cleaning. What has already been explained is omitted here. To disengage the valve body 100 from the device, the cap nut 18 is turned in the R direction, moving the valve body 100 in the V direction to move it away from the cap nut 18 . FIG. 21 shows the valve body 100 moved away from the arm 105 . Since the valve body 100 is extracted from the groove 105b having a larger width in the arm 105, the arm 105 lifts upwards and extends the cylindrical arm 106a so that the valve body 100 is extracted from the groove 105b along the direction T. Additionally, when the valve body 100 has been removed from the cap nut 18, it can be lowered to remove the stem 104 from the cylindrical arm 106a, thereby allowing the stem 104 to be removed from the groove 105b.

Embodiment 11: FIG. 22 shows the construction of an externally cooled valve body 131 . A cooling block 133 and a cooling tube 132 can be fixed to the valve body 131 by welding or brazing. When the cooling water flows from F through the cooling pipe 132, the cooling block 133 and the valve body 131 can be cooled to cool the carbonated liquid inside. Soldering or brazing results in better heat transfer.

Although the invention has been described in connection with carbonated liquids, it is also applicable to non-carbonated beverages.
