[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0020] See also Figures 1 to 4The utility model provides a technical solution: a valve plugging device, including an inlet plugging cover corresponding to the valve inlet and an outlet plugging cover corresponding to the valve outlet, the inlet plugging cover including an inlet plugging cover body 1, the outlet plugging cover including an outlet plugging cover body 2, both the inlet plugging cover body 1 and the outlet plugging cover body 2 are provided with abutment structures, the inlet plugging cover body 1 and the outlet plugging cover body 2 are provided with a connecting structure on the side away from the abutment structure, the inlet plugging cover body 1 and the outlet plugging cover body 2 are connected with an air pipe, the air pipe corresponds to the connecting structure, and the surface of the entire device is subjected to yellow anodizing treatment, which can extend the service life of the device.
[0021] In this embodiment, vents 3 are provided in both the inlet plugging cover body 1 and the outlet plugging cover body 2. The inlet plugging cover body 1 and the abutting structure and the connecting structure located on the inlet plugging cover body 1 are an integrally processed structure. The outlet plugging cover body 2 and the abutting structure and the connecting structure located on the outlet plugging cover body 2 are an integrally processed structure. The abutting structure is an abutting block 4. Sealing gaskets are installed between the abutting block 4 and the valve inlet and the valve outlet. The abutting block 4 is a flat-bottomed conical structure.
[0022] Specifically, when it is necessary to install the inlet plugging cover body 1 and the valve inlet, put the sealing gasket on the abutment block 4, and then insert the abutment block 4 into the valve inlet, so that the inlet plugging cover body 1 and the valve inlet can be installed and fixed. Similarly, the outlet plugging cover body 2 and the valve outlet can be installed and fixed.
[0023] The connection structure is a joint 5, and an external thread 6 is provided on the circumference of the joint 5. The joint 5 corresponds to the air pipe, and the diameter of the external thread 6 is 14 mm.
[0024] When it is necessary to connect the air pipe, the joint 5 is directly fixed to the air pipe through the external thread 6, and the joint 5 matches the air pipe, thereby ensuring the sealing effect.
[0025] Specifically, when a test is required, the abutment block 4 of the inlet plugging cover body 1 can be inserted into the valve inlet so that the inlet plugging cover body 1 abuts against the valve inlet. At this time, the flat-bottomed conical structure of the abutment block 4 can ensure stability and prevent the inlet plugging cover body 1 from shaking. Then the joint 5 is fixed to the trachea thread, and the experimental equipment can be connected through the trachea to carry out air supply, exhaust and flow monitoring, thereby ensuring air tightness during the entire experimental process.

The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
