Abstract:
A method is provided for carrying out a sound test for detecting and/or analyzing material faults and/or mounting faults of at least one component, in which the component is excited, by striking, to experience vibrations which generate soundwaves, after which the generated soundwaves are detected and conclusions are drawn about material faults and/or mounting faults on the basis of the detected soundwaves, wherein the striking of the component and the detection of the vibrations are carried out using an endoscope device. In addition, embodiments of the present invention relates to an endoscope device which is configured to carry out the method.
Abstract:
A valve for shutting off and/or controlling the throughflow of fluid flows is provided. A valve housing, having a valve seat contact surface, a valve cover with a valve cover thickness which is provided with a material allowance, and the valve body form together a first, maximum lift; and when the worn region of the valve seat contact surface is removed, the valve cover thickness can be removed such that the first, maximum lift remains the same or remains the same with only minor deviations; and/or the valve housing, valve seat contact surface, valve cover with the valve cover thickness, and the valve body is provided with a material allowance form a first, particularly maximum lift; and when the worn region of the valve seat contact surface is removed, the valve body can be removed such that the first, maximum lift remains the same or with only minor deviations.
