1. the sealing performance of the air valve is improved to about 99% from the original about 80%; the one-time passing rate of a pipeline tightness test using the air valve is improved from the original 50% to 85%;

2. the application field of the air valve is enhanced, the original harmful gas conveying pipeline and the dry gas conveying pipeline and other special gas pipelines cannot meet the requirement due to the air valve sealing property, so that the PP air pipe cannot be used, only stainless steel welding air pipes or other special pipelines with the manufacturing cost about 3 times that of the PP air pipe can be selected, and the construction period is long and the initial engineering investment cost is high;

3. the system operation cost is saved, particularly after the high-standard sealing air valve is adopted in the drying room in the lithium battery industry, the operation cost of the air conditioning system of the drying room is saved by about 30%, the consistent good comment of owners is obtained, and due contribution is made to energy conservation and emission reduction.
