Description

Valve body seal detection device Technical Field The utility model relates to the technical field of valves, in particular to a valve body sealing detection device of a valve. Background In the field of industrial production, valves are used as key components for controlling fluid delivery, and the sealing performance of the valves is directly related to the safe and stable operation of the system. The sealing reliability of the valve is critical whether the transportation of flammable and explosive media in the petrochemical industry or the stable supply of water resources in an urban water supply system is guaranteed, so that the sealing detection of the valve body becomes a necessary procedure in the production link; The existing valve seal detection device has a plurality of problems in practical application. In the fixed mode, the traditional device generally relies on flange bolts to fasten the valve, and the operation flow is complicated, workers need to screw the bolts one by one, so that a large amount of labor and time cost are consumed, the torque of each bolt is difficult to accurately control in the screwing process, and uneven stress on the periphery of the valve flange is caused. When in detection, the partial sealing performance of the valve can be misjudged due to inconsistent pressure distribution, and the accuracy and reliability of a detection result are seriously affected. In the aspects of pressure monitoring and safety protection, most traditional detection devices lack perfect pressure regulation and emergency pressure relief mechanisms. When the pressure is abnormally increased in the detection process, the device cannot respond in time, so that the valve can be damaged by overpressure, and serious safety accidents such as internal high-pressure medium injection and the like can be even caused.
