This invention provides a valve internal leakage diagnostic device, including a valve body, a hollow support base integrally connected to the middle of the valve body, an internal sealing assembly inside the hollow support base, a rotating handwheel connected to the top of the internal sealing assembly, pipes connected to both sides of the valve body, flanges connected to the ends of the pipes, four sets of mounting holes evenly distributed on the flanges, an adjustable support assembly fitted on the outer wall of the pipes, and an internal leakage detection assembly connected to the side of the adjustable support assembly facing the outer wall of the pipes. This invention has the following advantages: its simple structure eliminates the need to disassemble the valve for inspection, and it can be directly installed outside the valve body, enabling the inspection of a large number of valves, thus avoiding the problem of some valves having internal leaks that are difficult to detect and thus causing leakage.

The application provides a multi-coil incremental permeability dynamic detection probe and a yield strength detection method. The probe mode of the multi-coil is used to detect different positions of materials in different magnetization states at the same time. In the movement process, the mechanical properties of the materials can be quickly and efficiently predicted. Compared with the traditional static detection mode, the dynamic detection probe can be used for continuous detection, so as to improve the detection efficiency and realize the purpose of pipeline detection operation.

The utility model discloses a sealing performance detection device for ball valve production, which comprises a frame, the inner wall of the frame is fixedly connected with a placing seat, the outer surface of the placing seat is provided with a placing groove, the inner wall of the placing groove is provided with a ball valve body, and the outer surface of the placing seat and the outer surface of the ball valve body are jointly provided with a fixing mechanism. The inner wall of the frame and the outer surface of the ball valve body are jointly provided with a sealing mechanism, and a water conveying mechanism is arranged on the outer surface of the sealing mechanism. The device can accurately control the movement of fixed clamping plates through an electric push rod in the fixing mechanism, enables the two fixed clamping plates to stably clamp a ball valve body in a placement groove, guarantees that the ball valve is in a stable state during detection, can drive a lifting plate to move up and down through a hydraulic cylinder in the sealing mechanism, and pushes the lifting plate to descend, thereby achieving the detection of the ball valve. The two sealing gaskets are tightly attached to the flanges at the two ends of the ball valve body, and the sealing gaskets and the flanges at the two ends of the ball valve body can form a good sealing effect.
