Nanofibers prepared by electrospinning technology have the characteristics of ultra-high specific surface area, extremely large aspect ratio, high surface activity, high strength and toughness, etc.

The nozzle 102 is a conical nozzle with threaded cavities at the bottom and top. The threaded end of the top of the nozzle 103 is directly installed in the threaded cavity installed at the bottom of the nozzle 102. The bottom mounting end of the electric valve seat 104 is directly installed in the threaded cavity installed at the top of the nozzle 102.
