When the operation of the operating lever 12 in the P direction is stopped, the valve portion 21V returns to the F side and the flow path valve 21 is closed. As a result, the pouring of the beverage from the nozzle 13 is stopped.

The spring 27 expands and contracts according to the movement of the opening / closing portion 21L while urging the opening / closing portion 21L. Here, since the spring 27 has a tubular collar 29 arranged around it, it is in a state where it is difficult to come off even if it receives vibration in the compressed state. Further, since the spring 27 has a tubular collar 29 arranged around the spring 27, it is difficult for the operator to touch the spring 27.

From the above, the beverage dispensing valve 100 according to the first embodiment is provided in the dispensing section 13 for pouring the beverage, the flow path 4 for supplying the beverage to the dispensing section, and the flow path 4 so as to be openable and closable. A flow path valve 21, an operation lever 12 that opens the flow path valve 21 by pressing the flow path valve 21, a spring 27 that urges the flow path valve 21 to be in the closed state, and a spring 27 are provided around the spring 27.

Further, since the valve portion 21V of the flow path valve 21 is urged by the spring 27 and kept in the closed state when the operating lever 12 is not operated, the beverage does not leak.

Other embodiments.
(Improvement inside the nozzle)
Next, a modified example of the nozzle 13 of the beverage dispensing valve 100 according to the first embodiment will be described with reference to FIGS. 7 to 9 as the nozzle 130 of the beverage dispensing valve 200. Here, the beverage dispensing valve 200 includes a valve body 10, an operating lever 12, and a nozzle 130, as shown in FIGS. 7 and 8. The nozzle 130 includes a beverage stock solution supply pipe 131, an outer cone 132, an inner cone 133, a first diffuser 134, a second diffuser 135, and a nozzle frame 136. A beverage stock solution flow pipe 3B and a carbonated water flow pipe 3C are connected to the valve body 10.

The carbonated water from the carbonated water flow pipe 3C passes through a slight gap between the outer cone 132 and the inner cone 133, and maintains a high carbon dioxide concentration in the beverage. Here, in order to maintain a high carbon dioxide gas concentration, it is necessary to remove only the inner cone 133 and periodically clean the narrow grooves provided in the inner cone 133. However, conventionally, when the inner cone 133 is removed, the outer cone 132 may also be removed.

Here, as the first step of the work, the nozzle frame 136 is removed, only the first diffuser 134 is removed, and the nozzle frame 136 is attached again. FIG. 9 shows a state in which only the first diffuser 134 is removed in the first stage of the work. Next, as the second stage of the work, when carbon dioxide gas is intermittently poured out from the nozzle 130 by operating the operation lever 12, only the inner cone 133 comes off due to the force of the carbon dioxide gas. In the state shown in FIG. 9, since the second diffuser 135 holds the outer cone 132, only the inner cone 133 is disengaged due to the force of carbon dioxide gas, and the outer cone 132 remains in the nozzle 130. Further, since the second diffuser 135 remains inside the nozzle 130, the carbon dioxide gas for removing the inner cone 133 is rectified by the second diffuser 135, and the scattering of the carbon dioxide gas to the periphery can be reduced.
