た。However, when the carbonated water passes through the passage and mixes with the syrup, the carbonated water is discharged from the passage directly before the carbonated drinking water discharge port of the nozzle without passing through the pressure reducing mechanism. As it is mixed with syrup, the shaking caused by the pressure drop on the carbonated water is severe and the bond between the carbon dioxide and the water becomes loose, and a large amount of the carbon dioxide dissolved in the water is disturbed and escapes at a stretch. However, there is a drawback that the concentration of carbon dioxide gas is low, that is, the loss of carbon dioxide volume is large. By the way, generally, the amount of gas dissolved in a liquid is proportional to the pressure according to Henry's law, and the dissolved amount increases as the temperature decreases. Therefore, as a countermeasure to the above problem, the carbonated water is cooled before the carbonated water pouring valve as described in JP-B-51-105638, or as described in JP-B-47-1825. Many attempts have been made to improve the piping in the carbonated water supply device by increasing the pressure applied to the carbonator. However, when such a device for piping is used, there is a problem that the piping becomes complicated and the size of the device increases and the cost increases, and a drastic solution has not yet been found.

It is an object of the present invention to provide a carbonated water pouring valve in which the release of carbon dioxide gas in carbonated water during pouring is reduced.

In the decompression device including the narrow grooves 14e , the gap 20 is formed annularly and the narrow grooves 14e are formed.
Because it is a large pressure reduction passage formed in long and area, moreover, the passage is a more larger structure toward the downstream. Therefore, carbonated water in the decompressor is
The flow velocity is slow, and further, it is further decelerated as it goes downstream, and it flows down over a long period of time, so that it is slowly and gently depressurized and discharged to the disc-shaped rectifying unit 15. Therefore, the fluctuation of the carbonated water in the decompression device is small, and the disorder of the connection between the carbon dioxide gas and the water in the carbonated water is reduced. Next, the carbonated water is guided by the U-shaped groove 16 of the disc-shaped straightening section 15 and gently flows down to the carbonated drinking water discharge port along the peripheral wall of the fitting hole 23 of the nozzle 22. Therefore, the fluctuation given to the carbonated water flowing down from the pressure reducing device to the carbonated drinking water discharge port 25 is suppressed, and the disorder of the connection between the carbon dioxide gas and the water in the carbonated water is reduced. In addition, the lower surface of the rectifying portion has a linear protrusion 1.
7 forms a gap as a flow path with the upper surface of the stepped portion 24 in the nozzle 22, and the upper surface of the stepped portion is an arc surface, so that the pressure reducing device discharges the carbonated drinking water. The flow to the outlet 25 is performed more smoothly, the fluctuation given to the carbonated water flowing down from the pressure reducing device to the carbonated drinking water discharge outlet 25 is further suppressed, and the disorder of the connection between carbon dioxide gas and water in the carbonated water is suppressed. It is further reduced.

That is, when the carbonated water passes through the gap 20 between the cylindrical cones 14 and 44 as the pressure reducing device and the cylindrical space portion 10, the carbonated water pouring valve described above,
Heat exchange with 44. Therefore, when the temperature around the drinking water supply device is high, such as in summer, the temperature of the cylindrical cones 14 and 44 may rise before the carbonated water is poured out. When water is poured out, the carbonated water is heated by the cylindrical cones 14 and 44, the bond between the carbon dioxide gas and water is weakened, and the water is poured out, whereby the carbon dioxide concentration is weakened. However, when the cylindrical cones 14 and 44 having low thermal conductivity are used, the heating amount in this portion is reduced and the decrease in carbon dioxide concentration is reduced.

Therefore, it can be used as a carbonated water pouring valve that obtains carbonated water of two kinds of concentrations, respectively depending on whether the cylindrical cone is attached or not attached. Further, the specifications of the cylindrical cones 14 and 44, for example, the axial length and diameter of the cylindrical cones 14 and 44, the radii of the circular arc portions 14d and 44d at the upper end of the outer peripheral surface, the shapes of the thin grooves 14e and 44e, the number, and the filter 31. Since carbonated water having different concentrations can be obtained by appropriately changing the presence or absence of the above or the specification thereof, the specification can be used as a carbonated water pouring valve for carbonated water of various concentrations.
