Casting machine for casting molten mass of light metal materials, comprises a mass container for the reception of fluent mass, a valve that is fluid connection with the mass container, and a pressure generation means

摘要

The casting machine comprises a mass container for the reception of fluent mass, a valve (6) that is fluid connection with the mass container, where the valve is in the presence of pressure drop along its valve-passage direction in an open condition and in the absence of pressure drop along its valve-passage direction in a closed condition, and a pressure generation means (8) for generating a pressure drop along the valve-diameter direction of the valve. The valve comprises a valve body with a valve opening and/or two valve flaps assigned the valve opening. The casting machine comprises a mass container for the reception of fluent mass, a valve (6) that is fluid connection with the mass container, where the valve is in the presence of pressure drop along its valve-passage direction in an open condition and in the absence of pressure drop along its valve-passage direction in a closed condition, and a pressure generation means (8) for generating a pressure drop along the valve-diameter direction of the valve. The valve comprises a valve body with a valve opening and/or two valve flaps assigned the valve opening, where the valve flap is hinged on the valve body and is suspended to an elastic bias, which presses the valve flaps and seals the valve opening. The valve flap is flexible and consists of a material that is bent in tensioned condition at the valve opening.
