Kushanda nheyo yeproportional solenoid valve
Inobva pamusimboti we solenoid on-off valve: kana simba rapera, chitubu chinotsikirira musimboti wakanangana nechigaro, zvichiita kuti valve ivhare. Kana iyo coil yasimbiswa, simba remagetsi rinogadzirwa rinokunda simba rechirimo uye rinosimudza musimboti, nokudaro richivhura vharuvhu. Iyo proportional solenoid valve inoita shanduko kune chimiro chesolenoid valve: inogadzira chiyero pakati pechitubu simba nemagetsi emagetsi pasi pechero coil ikozvino. Saizi yekoiri yazvino kana saizi yesimba remagetsi inokanganisa kurova kweplunger uye kuvhurwa kwevhavha, uye kuvhurwa kwevharuvhu (kuyerera) uye coil ikozvino (tsamba yekudzora)
Ndiyo yakanakira mutsara hukama.
Direct acting proportional solenoid valve inoyerera pasi pechigaro. Iyo yepakati inoyerera ichibva pasi pechigaro, uye kwakananga kwesimba kwakafanana neremagetsi emagetsi, uye zvakapesana nechisimba chechirimo. Nokudaro, zvakakosha kuisa huwandu uye hushoma hunoyerera hunoenderana nehuwandu hwekushanda (coil current) mumamiriro ekushanda. Iyo proportional solenoid valve yeDrey fluid yakavharwa (NC, inowanzovharwa rudzi) kana simba radzimwa.
