[0002] A piezoelectric valve is a two-position control valve made using the principle that functional ceramics produce bending deformation under the action of voltage. The piezoelectric valve can be used to control the direction of glue spraying. It uses the characteristics of piezoelectric ceramics to convert electrical energy into mechanical energy, thereby producing a spraying effect. During production and processing, the glue in the hose is sprayed onto the semi-finished product through the glue outlet nozzle through the piezoelectric valve.

The disassembly process is relatively cumbersome, which increases the labor intensity of the staff to a certain extent.
