A Nozzle Adjustable Adaptive Piezoelectric Injection Valve

Abstract

The invention belongs to the technical field of piezoelectric injection valves, and in particular relates to an adjustable nozzle adaptive piezoelectric injection valve, which includes a valve body, a valve seat, an adjustment mechanism and a controller, and the valve seat is detachably connected to the valve body , the valve seat is threadedly connected with a gear nut, the gear nut is provided with a nozzle, the gear nut can adjust the up and down position of the nozzle by turning, the adjustment mechanism includes a servo motor and a transmission gear set, the The servo motor is fixedly installed on the valve body and is electrically connected to the controller, and the servo motor is connected to the gear nut through the transmission gear set. Compared with the prior art, the present invention realizes the automatic adjustment of the position between the nozzle and the striker by setting the adjustment mechanism and the controller, which greatly improves the consistency of dispensing. In addition, the present invention can also adjust the position of the nozzle. Automatic compensation, thus improving the accuracy of dispensing and the service life of the device.

Description

technical field

[0001] The invention belongs to the technical field of piezoelectric injection valves, in particular to an adjustable nozzle self-adaptive piezoelectric injection valve. Background technique

[0002] Piezoelectric injection valves use the characteristics of piezoelectric materials to generate mechanical force through voltage to control the opening and closing of the valve. Because the space for opening and closing the valve is very small, the piezoelectric action frequency is extremely high, and it can inject a very small amount of water at high speed. Therefore, piezoelectric injection valves are widely used in the field of high-precision, high-reliability dispensing.

[0003] At present, the piezoelectric injection valve needs to be regularly disassembled and cleaned for maintenance. In order to adapt to high-precision dispensing, the piezoelectric injection valve needs to strictly control the relative position between the nozzle and the striker during the ...

[0025] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0026] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", horizontal" etc. are based on th...
