Background
The roundness of a valve body of a biological airtight valve used in the current market is poor, the butterfly plate is simple in structure, and deformation easily occurs in the production process, so that the airtight effect of the valve body is influenced. The butterfly plate sealing element is generally made of rubber materials, and is easy to deform after being used for several times, and although the deformation has certain recovery capacity, the sealing performance of the butterfly plate sealing element is greatly influenced at different temperatures, so that the application range of the valve is influenced. In addition, the fixing mode of the existing sealing ring and the butterfly plate is single, the butterfly plate needs to be provided with holes, and leakage points of the butterfly plate are increased. For some biological studies, especially some organisms that are toxic or do not allow leakage, the bio-containment valves currently on the market are at great risk. In addition, in the existing biological airtight valve on the market, the valve rod can cause sealing leakage due to sinking in the long-term use process.
Accordingly, in order to solve the above problems, the present invention provides a bio-hermetic valve having high sealing performance.
