A pipeline structure (1) with a valve, comprising:
- a connection pipe (10), comprising:
- an inflow passage (100) and an outflow passage (200);
- and
- an accommodation part (300), located between the inflow passage (100) and the outflow passage (200), the accommodation part (300) having:
- a flow chamber (310), having an upper flow chamber (311) and a lower flow chamber (312) that are in fluid communication with each other;
- a first inlet channel (320), in fluid communication with the inflow passage (100) and the upper flow chamber (311), wherein the first inlet channel (320) is formed by a side wall (SW) standing at the inflow passage (100), the first inlet channel (320) has an inlet section (321) in fluid communication with the inflow passage (100), the inlet section (321) has an opening that has a size increasing along a direction away from the inflow passage (100), and the inlet section (321) with the size of the opening increasing along the direction away from the inflow passage (100) is in uninterrupted space communication with and in uninterrupted fluid communication with the inflow passage (100) and the upper flow chamber (311);
- a second inlet channel (330), in fluid communication with the inflow passage (100) and the lower flow chamber (312);
- and
- an outlet channel (340), in fluid communication with the lower flow chamber (312) and the outflow passage (200);
- and
- a flow controller (20), disposed in the flow chamber (310), wherein the flow controller (20) is configured to selectively enable or interrupt a fluid communication between the upper flow chamber (311) and the lower flow chamber (312) and a fluid communication between the second inlet channel (330) and the lower flow chamber (312), and the flow controller (20) comprises:
- an elastic pad (400), disposed in the flow chamber (310) to divide the flow chamber (310) into the upper flow chamber (311) and the lower flow chamber (312), wherein the elastic pad (400) is elastically deformable in the flow chamber (310) so as to selectively enable or interrupt the fluid communication between the second inlet channel (330) and the lower flow chamber (312), the elastic pad (400) has a hole (411) in fluid communication with the upper flow chamber (311) and the lower flow chamber (312);
- wherein a fluid pathway to the upper flow chamber (311) from the inlet section (321) with the size of the opening increasing along the direction away from the inflow passage (100) is spaced apart from the elastic pad (400), and the size of the opening of the inlet section (321) increases directly from a boundary between the first inlet channel (320) and the inflow passage (100).
