[0033] The following is combined with Figures 1-6 This application is described in further detail.

[0034] Example 1

[0035] The present application embodiment discloses a stainless steel quick connector for use in the pharmaceutical industry. Figure 1 The stainless steel quick connector includes a male connector 1 and a female connector 2 that are interconnected. The male connector 1 includes a plug portion 11 and a connecting pipe 3 welded to the plug portion 11. The female connector 2 includes a socket portion 21 for connecting to the plug portion 11 and a connecting pipe 3 welded to the socket portion 21. Each connecting pipe 3 is detachably connected to the corresponding demand pipe, making it easy to replace the male connector 1 or female connector 2 at the customer's demand end.

[0036] Each connecting pipe 3 includes a connecting section 31, the outer wall of which is fixedly connected to multiple raised rings 311. These raised rings 311 are evenly distributed along the axis of the connecting section 31. This allows the hose-made demand pipe to be tightly fitted around the outer edges of the raised rings 311, thereby completing a tight connection between the demand pipe and the corresponding connecting pipe 3. This enhances the stability and sealing of the connection.

[0037] A check valve is installed in the plug portion 11 or the socket portion 21 to reduce the backflow of liquid or gas in the quick connector and ensure the safety of the production process. A flow meter is installed in the plug portion 11 or the socket portion 21 at the same time.

[0038] The stainless steel quick connector for the pharmaceutical industry in this embodiment is designed as follows: when the male connector 1 and the female connector 2 are independent, they are both sealed; when the male connector 1 and the female connector 2 are quickly connected together, liquid or gas can flow through the quick connector.
