Test device for detecting sealing performance of one-way valve

A test device for detecting sealing performance of a one- way valve, comprising:

• a box, provided with a gas inlet pipe and a gas outlet pipe, wherein the gas inlet pipe is communicated with a gas source;
• a detection device, communicated with the gas outlet pipe, wherein the detection device is used to detect detection gas input into the box by the gas source;
• a sleeve, connected to the gas inlet pipe, wherein one end of the sleeve is communicated with the gas source, and the other end of the sleeve has a gas outlet;
• a fitting piece, wherein one end of the fitting piece is used to block the gas outlet;
• a driving member, connected to the box, wherein the driving member is also connected to the other end of the fitting piece and used to drive the fitting piece to move and rotate;
• wherein the sealing performance is characterized by a leakage rate of a sealing structure between the sleeve and the fitting piece.
