In pharmaceutical factories, production of related pharmaceutical agents is generally performed using a sterile closed mechanism. The material inlet on the aseptic closed mechanism needs to be provided with an aseptic isolation valve so as to realize sterility in the material feeding process. Based on the sterility requirements of the process, the sterile isolation valve must have a good seal to avoid the ingress of contaminated air. Thus, an enterprise manufacturing the aseptic isolation valve needs to perform tightness detection on the aseptic isolation valve after the aseptic isolation valve is manufactured, so as to detect whether the aseptic isolation valve leaks.

Through mass search, the prior art with publication number of CN214893926U discloses a sterile isolation valve leakage detecting device, which comprises a shell, wherein the shell is provided with a detecting end and an operating end; the detection end is provided with a detection through hole; a speed-regulating air pump, a three-way pipe and a pressure sensor are arranged in the shell; the first pipe orifice end of the three-way pipe is connected with the speed-regulating air pump, the second pipe orifice end of the three-way pipe is internally provided with a pressure sensor, and the third pipe orifice end of the three-way pipe is connected with the detection through hole; a control module is also arranged in the shell; the pressure sensor and the speed regulating air pump are electrically connected to the control module. The utility model has the advantages of compact structure, low manufacturing cost, good detection effect, high detection efficiency and great economic value.

In summary, in the use process of the existing leak detection device, the gas pumped into the detection through hole by the air pump is not filtered, so that a certain pollution is caused to the sterile isolation valve to be tested; and the sterile isolation valve to be tested is simply installed with the detection shell through the clamping end, so that the tightness of the sterile isolation valve cannot be ensured.
