The invention belongs to the technical field of fluid dispensing valves, and particularly discloses a dispensing valve with hot melt adhesive driven by a single piezoelectric ceramic. A nozzle of thedispensing valve can be detachable and replaced, and nozzles of different bore diameters can be replaced according to actual needs. A reset spring occupies small area, and only a few components are required to be installed in a valve body. Since an integral cutting molding manner is adopted, components inside are convenient to mount, so that the whole structure of the dispensing valve is more compact. A striker and a lever are separated, so that the striker does not move along with swing of the lever, thus avoiding that transverse displacement generates on the striker when the lever swings. Inthis way, the dispensing valve is good in guiding property and stable in movement, and glue sealing can be facilitated, thus prolonging the service life of the dispensing valve and ensuring the dispensing valve can carry out
