[0010]

According to the present invention, the movable tank side can be easily opened and closed by using a manual valve with a lever, and the connection part on the fixed pipe side is made a side seal to separate the valve pressure resistance from the influence of the operating spring. Further, the valve stem of the fixed-side opening / closing valve element 8 is locked when closed, and the force of the fixed-side spring 14 and the force of the movable-side spring 18 are offset, so that operation can be performed without a large air pressure or cylinder pressure. It is like that.

[0011]

The connecting device for the movable tank to the fixed conduit according to the present invention is as described above, so that it can easily operate with a small air pressure or a small cylinder pressure.
