AI Technical Summary
In existing liquid conveying equipment, traditional discharge nozzles are prone to dripping when closed, especially in the conveying of high-viscosity or corrosive liquids, where the sealing performance is insufficient and cannot meet the requirements of environmental protection and production efficiency.
A liquid anti-drip feed nozzle was designed, which uses a stainless steel woven mesh as a filter to increase the surface tension of the liquid droplets. The sealing ring and the inner flange of the mesh frame plug form a tight fit to ensure that the liquid does not drip. It is also suitable for manual or electric control.
It achieves leak-free operation in the transportation of high-viscosity or corrosive liquids, improves sealing performance, reduces system costs and maintenance difficulty, has a wide range of applications, and is easy to operate.
