られた状態となる。According to the above-described structure, when the first flow path opens the valve body of the first valve seat using the driving means, the fluid entering from the first inflow path flows into the first valve seat and the first valve downstream chamber. It flows to the first outflow path. On the other hand, in the second flow path, the pressure in the downstream chamber of the first valve is guided to the pressure receiving chamber via the signal path and acts on the diaphragm valve, so that the second valve seat is in a closed state.

２弁下流室を経て＠２流出路へ流れる。Next, when the valve body of the first valve seat is closed by the driving means, the flow in the first flow path is stopped. On the other hand, in the second flow path, the pressure in the downstream chamber of the first valve decreases and the internal pressure in the pressure receiving chamber also decreases, so the diaphragm valve is pushed open by the fluid pressure in the second inflow path and is opened. As a result, the fluid entering from the second inflow path flows to the second outflow path via the second valve seat and the second valve downstream chamber.
