A New Type of Precision Piezoelectric Injection Valve

Abstract

The invention discloses a novel precision piezoelectric injection valve, belonging to the technical field of piezoelectric injection valves, comprising a socket, the socket and a control board installed in an end cover, the end cover, an adjusting screw, a flow channel assembly, and an amplifying lever , power components and fixed hinges are installed on the body. In the present invention, the nozzle is fixedly installed through the cooperation of the designed end cap, adjusting screw, flow channel assembly, amplifying lever, power assembly, fixed hinge, body and knob handle, and the position of the nozzle will not be loosened after a long time of work. , prolong the interval between regular nozzle calibration, reduce maintenance time, improve the stability of continuous work, the position of the flow channel can be adjusted, and the position of the valve body is more flexible in the face of complex working environments. , to facilitate maintenance, improve maintenance efficiency, effectively improve the accuracy of the value between the striker and the nozzle, and avoid a large pressure between the striker and the nozzle.

Description

technical field [0001] The invention belongs to the technical field of piezoelectric injection valves, in particular to a novel precision piezoelectric injection valve. Background technique [0002] The injection valve uses the characteristics of piezoelectric materials to generate mechanical force through voltage. When the piezoelectric material below is charged, the valve opens, and when the piezoelectric material above is charged, the valve closes. Because the space for opening and closing the valve is very small, The action frequency is extremely high, and a very small amount of liquid material can be ejected at high speed. Known and potential technologies include piezoelectric ceramics, lever amplification mechanism, nozzle calibration, high-precision dispensing and ultra-micro-dispensing. [0003] The fields of application of piezoelectric injection valves include the electronics industry, mobile communication industry, automobile industry, photovoltaic and semiconduct...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to disclose a new type of precision piezoelectric injection valve, which solves the technical problem: it is difficult to calibrate after the nozzle and the striker are worn out, even after calibration, the position of the nozzle is difficult to maintain, and it is easy to occur during work It is loose and out of position, and the flow path of the nozzle is inconvenient to disassemble and assemble, so the position accuracy of the nozzle cannot be guaranteed after repeated disassembly and assembly. The position is not flexible, which easily affects the construction efficiency. When using the screw to adjust the positional relationship between the striker and the nozzle, in the process of turning the screw, the adjustment accuracy is low, and it is easy to cause the power component and the amplifying lever to press down. It will increase the wear degree of the nozzle and the striker per unit time, and a new type of precision piezoelectric injection valve is proposed
