Porcelain consists of two parts inside piezoelectric ceramics as actuating element, respectively upper piezoelectric ceramics 2 and pushes electroceramics 3, and this two
Partial pressure electroceramics gauge size is the same, and what every part laminate electrode was taken is interdigitated connection type in parallel；Lamination pressure when assembly
Electroceramics (2+3) is clamped between displacement amplifying mechanism 4 and valve body 1, is fastenedly connected by fastening bolt 5；Striker 7 is driving in Fig. 2
It moves up and down under the action of dynamic device, fluid injection is gone out by the shock with nozzle 8 (Fig. 3).
The nozzle has the disadvantage in that
Nozzle is single entirety, and difficulty of processing is big, and certain technological levels are unable to reach design requirement, and it is empty to limit design
Between；Nozzle be surface-treated it is more difficult, since nozzle arrangements are more complex, to single surface carry out processing difficulty it is larger.
Utility model content

Type is easy to process, improves nozzle design space, guarantees the stability of nozzle effect.
It is as follows that the utility model provides technical solution:
A kind of split type nozzle, including mutually independent nozzle body one and nozzle body two, in which:
The nozzle body one is located at two top of nozzle body, and the nozzle body one includes fluid space and jet passage
One, the nozzle body two includes jet passage two；The nozzle body two is that hydrophobic oleophobic material or the nozzle body two have
Hydrophobic oleophobic coating.
Further, the split type nozzle further includes locking nut, and the nozzle body one and nozzle body two are positioned at described
In locking nut, the locking nut lower end is provided with inside limiting section.
Further, the nozzle body two is provided with the protrusion for lengthening the jet passage two.
Further, the thickness of the protrusion from centre gradually become smaller around or the protrusion everywhere in it is thick
It spends equal.
Further, the nozzle body one is wear-resistant material.
A kind of piezo jet valve, including valve body and split type nozzle above-mentioned, the locking nut are connect with the valve body.
Further, the locking nut and the connection type of the valve body be threadedly coupled, Nian Jie or mating connection.
The utility model has the following beneficial effects:
The split type nozzle of the utility model is easy to process, reduces the processing cost of nozzle, and it is empty to improve nozzle design
Between；And nozzle be surface-treated simply, and the hydrophobic oleophobic effect of nozzle can be improved, guarantee the stability of nozzle effect.
