In addition, when the operation unit 35 pushes in the main seal packing 105, the space below the flange 38 in the space between the operation member 30 and the cover unit 31 and the gas flow path 107 of the spear valve 102 communicate with each other. The

  When gas is introduced into the gas flow path 16 in this state, the gas is guided to the gas passage 41 via the gas flow path 16. The gas in the gas passage 41 spreads the side packing 39 outward and flows into the space between the operation member 30 and the cover part 31, and then flows into the beer barrel 100 through the gas flow path 107. And the drink in the beer barrel 100 is pushed out from the drink extraction pipe | tube 104 by this gas. As described above, in the state of FIG. 7, the beverage extraction pipe 104 and the internal space of the operation unit 35 communicate with each other, so that the beverage pushed out from the beverage extraction pipe 104 is discharged from the internal space of the operation unit 35 to the beverage passage. 40 and the beer hose 36 can be fed into a predetermined beverage dispensing destination such as a dispenser.

  In order to remove the dispensing head 1 from the base part 101, the operation handle 12 is first returned to the closed position, and then the dispensing head 1 is removed from the base part 101. By operating the operation handle 12 upward, the plunger 11 moves to the closed position, so that the operation member 30 is pushed upward by the coil spring 106 of the spare valve 102. As a result, the engaging claw 33 of the insertion disk 3 is reengaged with the groove 14 a of the head body 2. Therefore, the head main body 2 and the insertion disk 3 can be removed integrally from the base part 101. In order to remove the insertion disk 3 from the head body 2, for example, as shown in FIG. 10, the operation handle 12 may be operated to the open position while the dispensing head 1 is not attached to the base 101. By this operation, the engagement between the engaging claw 33 of the insertion disk 3 and the groove 14a of the head body 2 is released, so that the insertion disk 3 can be easily detached from the head body 2.

  As described above, according to the dispensing head 1 of the present invention, the insertion disk 3 provided with the beverage passage 40 is detachable from the head body 2, so that the insertion disk 3 is removed from the head body 2 during maintenance. Can be cleaned or the insertion disk 3 can be replaced. Therefore, the maintenance work of the dispensing head 1 can be reduced. Further, in the dispensing head 1, after the insertion disk 3 is attached to the head main body 2, these can be handled integrally when being attached to the base part 101 and when being removed from the base part 101. Therefore, it can be mounted on the beer barrel 100 or removed from the beer barrel 100 by the same mounting method as a conventional dispensing head in which a beverage passage is provided in the head body.

  As shown in FIG. 3, the insertion disk 3 is in a state where the cover portion 31 is fitted into the mounting portion 14, the engagement claw 33 is engaged with the groove 14 a, and the insertion portion 11 a of the plunger 11 is inserted into the fitting hole 34. Attached to the head body 2. Therefore, the insertion disk 3 can be easily coaxially attached to the head main body 2 by meshing the engagement claw 33 and the groove 14a and inserting the insertion portion 11a into the fitting hole 34. Further, by fitting the cover portion 31 to the mounting portion 14, the operation member 30 can be easily attached to the head main body 2 in a state in which the operation member 30 is movable in the axial direction.

  The valve body 19 provided in the gas flow path 16 of the plunger 11 closes the gas flow path 16 when the plunger 11 is in the closed position. When the plunger 11 moves to the open position, the valve element 19 comes into contact with the operation member 30 and gas. The channel 16 is opened. Therefore, by providing such a valve body 19, when the plunger 11 is in the closed position, it is possible to prevent the introduction of useless gas from the gas flow path 16 ahead.

  As described above, since the cylindrical portion 39b of the side packing 39 functions as a check valve, the side packing 39 can prevent the backflow of gas from the beer barrel 100 into the gas passage 41. Therefore, it is possible to prevent the gas passage 41 and the gas passage 16 from being contaminated with the mist of the beverage with a simple configuration without providing a check valve in the portion where the gas flows.

  Since the beverage passage 40 is formed such that the second section 40b on the outlet side where the connection tool 37 is provided extends obliquely upward, it is possible to prevent the beverage from remaining at least in the second section 40b. Therefore, the beverage remaining in the beverage passage 40 can be reduced.

  The present invention may be implemented in various forms without being limited to the form described above. For example, the operation member of the insertion disk and the cover part may be integrated. In this case, the spear valve is opened and closed by the plunger moving the entire insertion disk in the vertical direction along the inner surface of the mounting portion. Plunger operating means for operating the plunger is not limited to the operating handle, and for example, a drive mechanism for driving the plunger using gas pressure may be provided in the head body.
