Technical Field

The utility model belongs to the technical field of the valve technique of dispensing and specifically relates to a high-speed dispensing valve.

Background

Along with the continuous development of society and scientific level, the civilization of human industry is continuously developed, more and more products are researched and prepared, and the dispensing machine is also called a glue spreader, a glue dispenser, a glue spreader, a glue filling machine and the like and is specially used for controlling fluid. And the fluid is dripped and coated on the surface of the product or an automatic machine inside the product, so that three-dimensional and four-dimensional path dispensing, accurate positioning, accurate glue control, no wire drawing, no glue leakage and no glue dripping can be realized. The glue dispenser is mainly used for accurately dispensing, injecting, coating and dripping glue, paint and other liquids in a product process to each accurate position of a product, and can be used for realizing dispensing, line drawing, circular or arc.
