The above-mentioned filling machine exhausts the air from the premises before filling the liquid, so it is possible to reduce the incorporation of air into the liquid, making it suitable for filling beer etc. However, it has the following problems. There were drawbacks.

In other words, one filling machine has, for example, 88 filling valves 1.
15, approximately four diaphragm valves 125 are used, and one relatively thick pipe 126 connects the volume valve 125 and the liquid tank 109. Piping 12 to the filling valve 115
7. 1zyb must be connected, and interposing a switching valve 128 in this piping and connecting the piping 130 leading to the manifold 129 not only requires a large number of switching valves 128, but also requires the piping around the switching valve 128. The work requires a large amount of man-hours.

There were problems such as. The present invention was proposed in view of the above points, and includes a valve body, a shaft movably attached to the valve body in an axial direction, and a switching lever rotatably attached to the valve body via the shaft. , a liquid passage and a gas passage formed between the valve body and the switching lever so as to be communicated with and disconnected from each other by rotation of the switching lever;
The valve body is characterized by comprising an air exhaust passage formed to communicate with and be cut off from the gas passage by movement of the shaft, and its purpose is to:
The object of the present invention is to provide a filling valve that can reduce the number of man-hours for piping work, simplify the structure, reduce costs, and facilitate maintenance.

Since the present invention is constructed as described above, it is only necessary to connect the air exhaust passage provided in the pulp body directly to the exhaust manifold, and this air exhaust passage can also be connected to the gas passage by moving the shaft. Since it is shut off, there is no need to insert a special switching valve in the gas piping and connect the air exhaust piping as in conventional systems, simplifying the configuration and requiring only one gas piping. The number of man-hours required will be reduced, reducing costs and making maintenance easier.

An embodiment of the present invention will be described below with reference to FIGS. 4 and 5.

In this embodiment, only the differences from the conventional one will be explained.

Also, the gas passage 8 is a passage 8B * 8b on the valve body 2 side.
* 8 ot and 8d and passages 88 and 8f on the switching lever 4 side, and are communicated and cut off by rotation of the switching lever 4.

Further, the air exhaust passage 9 is connected to a space 9a for moving the shaft 3 which is connected to the gas passage 8°, and the opening of the air exhaust passage 9 to the space 9a is connected to the shaft 3 for mounting the switching lever. A switching valve 3a formed at one end is interposed.

This switching valve 3a connects and shuts off the air exhaust passage 9 and the gas passage 8c by sliding the shaft 3 in the axial direction.It is normally biased to the shutoff position by a spring 10, and the shaft 3 is connected to the first
Cam 1 located at the same position as cam 131 shown in the figure
When it is engaged with 1 and pushed in, it moves to the communication position.

A throttle 12 is provided in the gas passage 8d to regulate the return gas velocity during liquid filling, and a seal member 13 is provided on the lower surface of the valve body 2.

Further, a liquid pipe 14 is provided between the liquid passage T of the filling valve 1 and the bottom of the liquid tank 109, a gas pipe 15 is provided between the gas passage 8 and the diaphragm valve 125, and a gas pipe 15 is provided between the air discharge passage 9 and the manifold 129. Air exhaust pipes 16 are connected between the two.

In the above configuration, when the bottle 101 is supplied to the filling valve 1 in the same manner as the conventional one, the shaft 3 is first engaged with the cam 11 and pushed in at position A shown in FIG.
moves to the communicating position, and as shown in FIG. , when the opening position shown in FIG. 1 is reached, the engagement between the cam 11 and the shaft 3 is released, and the switching valve 3
a returns to the cutoff position, and the switching lever 4 is rotated by means not shown, so that the gas passage 8a on the valve body 2 side is opened as shown in FIG.

ab, so, sd and gas passages 8o, 8 on the switching lever 4 side
f communicates with each other, the counter pressure gas in the liquid tank 109 is introduced into the bottle 101, and the inside of the chamber is pressurized to the same pressure as the inside of the liquid tank.

Subsequently, the switching lever 4 is rotated to the position C shown in FIG.
As shown in FIG. 5 (■), the liquid passage 7a on the valve body 2 side,
7b and the liquid passage T on the switching lever 4 side.

The gas passages 8a and 8d on the valve body 2 side are communicated with each other.
The gas passage 88 on the switching lever 4 side communicates with the gas passage 88, liquid filling is started, and the gas in the field returns to the liquid tank.

In this way, filling of the liquid is completed by the time the switch reaches the second position shown in FIG.

Then, the bottle 101 is lowered and transferred to the checking machine by the star wheel at the water position shown in FIG. The state shown is reached, and the bubbles in the gas passage 8 are discharged to the outside by the counter pressure gas in the liquid tank 9, and the switching lever 4 is rotated to the position where it blocks the gas passage 8 at the position shown in Fig. 1. The bottle is rotated to the feeding position.

As is clear from the above description, according to the present embodiment, an indoor air exhaust passage 9 is provided in the valve body 2, and this passage is formed by the switching valve 3 which is configured by also serving as the mounting shaft 3 of the switching lever 4.
Since it is possible to communicate with and shut off the gas passage through a, there is no need for a special switching valve like the conventional one, and the gas pipe 15 between the diaphragm valve 125 and the filling valve 1
Since only one pipe is required, the structure is simple and the number of man-hours required for piping work can be reduced, reducing costs and making maintenance easier.

Moreover, since the indoor air discharge passage 9 provided in the valve body 2 can be used as a flow path for cleaning liquid during cleaning, it is possible to improve the cleaning effect.
