| 摘要 |
The present invention relates to a sealed electronic valve which is pressed against the outside of a fluid passage and has an electromagnet and a steel plate or an electromagnet and an electromagnet installed thereon, so as to control the inside of the fluid passage between the electromagnet and the steel plate or the electromagnet and the electromagnet and control the flow of fluid that passes the inside of the fluid passage by means of a permanent magnet, according to a change in the polarity of the electromagnet(s) caused by a sudden supply of power. Because an electromagnet and a steel plate or an electromagnet and an electromagnet that move a permanent magnet controlling the flow of fluid are disposed outside a fluid passage, there is no need for electrical wire connections into the inside of the fluid passage, and therefore, there is the effect in that the sealing force required for the fluid passage can almost completely be provided. |
