Abstract

본 발명은 솔레노이드 밸브에 관한 것으로서, 보이스코일과 영구자석을 도입하여 고성된 보이스 코일 솔레노이드 밸브에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solenoid valve, and relates to a voice coil solenoid valve that is solidified by introducing a voice coil and a permanent magnet.

이는 유체통로를 개폐하는 밸브와 상기 밸브와 결합되는 것으로 코일이 감긴 보빈을 갖는 보이스코일형 이동자와, 상기 보이스코일의 내측에 삽입되는 제1자극과, 외측에 대향위치되는 제2자극을 갖는 영구자석형 고정자를 구비하는 것을 특징으로 하는데, 이러한 구조상의 특징으로 말미암아 입력신호에 대한 빠른 응답특성 및 밸브작동의 안정성, 그리고 정밀도를 확보할 수 있어 프린터 헤드등 미소 고속제어가 필요한 부분에 적용될 경우 대단히 빠른 인쇄 속도의 향상을 꾀할 수 있게 된다. 뿐만아니라, 보이스 코일을 유체의 통로에 위치시켜 유체에 의한 자연냉각 효과를 거둘수 있도록 구성해 종래의 솔레노이드 밸브 방식에서의 발열처리 문제 또는 효율적으로 해결 할 수 있게 된다.It is a permanently having a voice coil type mover having a valve that opens and closes a fluid passage and a coil wound bobbin, a first magnetic pole inserted into the inner side of the voice coil, and a second magnetic pole opposed to the outer side. It is characterized in that it is equipped with a magnetic stator, and this structural feature ensures a quick response to the input signal, stability of the valve operation, and accuracy, so when applied to the part that requires high-speed control such as a print head It is possible to improve the printing speed faster. In addition, by placing the voice coil in the passage of the fluid to achieve a natural cooling effect by the fluid can be solved the problem of heat generation in the conventional solenoid valve method or efficiently.
