A Study on the Improvement of Attraction Force of Solenoid Operated Valves

솔레노이드 밸브의 흡인력 개선을 위한 연구

In this research, we studied on improvement of the attraction force of solenoid operated valve for normal operation in harsh environment like vessel. Attraction force of the solenoid valves is effected by the B-H characteristics of magnetic material and the size of coil. In order to specify impact of the affection, we performed the B-H characteristics test and attraction force. Test results show that magnetic flux densities of the materials are difference each other more than 2 times in same magnetic intensity, and attraction force of the solenoid valve is 1.7 times difference as changes of resistance and the number of coil winding of solenoid.
