1. , for preventing the valve module in the dead leg space in container or pipe, described valve module comprises:

  • Plug accessory, it is for being attached to flexibility or the semi-rigid walls of described container or pipe by described valve module, described plug accessory comprises on the side of annular flange flange for the flexibility or semi-rigid walls that are arranged on described container or pipe, to make in described annular flange flange the aperture in the flexibility of opening in the heart and described container or pipe or semi-rigid walls be communicated with;

    Hollow housing, it is attached to the annular flange flange of described plug accessory or combines with its entirety, and described hollow housing comprises;

    Liquid inlet, the liquid that open communication in the heart in itself and described annular flange flange and being configured for receives from described container or pipe;

    Liquid outlet;

    Gas ports, it is configured to be attached to gas passage and valve, and wherein, described valve constitution becomes optionally to allow air-flow enter in described gas ports or leave described gas ports;

    WithInflatable and the bellows that can release or sacculus, it is fluidly connected to described gas ports, and be configured to the inflation when gas to flow in described gas ports and flows in inflatable bellows or sacculus in one way, thus to stop in described annular flange flange the aperture in the flexibility of opening in the heart and described container or pipe or semi-rigid walls, and release when vacuum is applied to described gas ports, thus cause gas to flow out described gas ports and flow out described bellows or sacculus, thus allow liquid to flow out described container or pipe, through the aperture in the flexibility of described container or pipe or semi-rigid walls, through described hollow housing, and flow out the liquid outlet of described hollow housing, described valve module thus the dead leg space in described container or pipe can be prevented.
