Mfundo yogwirira ntchito ya valavu yothandiza

1. Kuthamanga kwapakati: thupi la valve la valve yothandizira mwachindunji lili ndi zida zosindikizira. Pamene kupanikizika kumaposa mtengo wokhazikitsidwa wa dongosolo, chida chosindikizira chidzatulutsa mphamvu, kukankhira spool ndi ndodo yokakamiza kumbali ina;
2. Mfundo yoyendetsera kayendetsedwe kake: Ngati kupanikizika kuli kwakukulu kuposa mtengo wokhazikika wa dongosolo, ndodo yowonongeka idzadutsa mu thupi la valve, kotero kuti spool imatsegulidwa, ndipo gawo la mafuta a hydraulic limatulutsidwa kuchokera ku doko lakusefukira;
3. Mfundo yolamulira: Pamene kupanikizika kuli kochepa kusiyana ndi mtengo wa dongosolo, ndodo yoponderezedwa idzakokedwa ndi pisitoni ndikubwereranso kubwerera mu nthawi, kotero kuti pakati pa valve ndi chokhazikika, kuti mupewe Kutuluka kwamafuta a hydraulic kuchokera padoko losefukira ndi kuthekera kwadongosolo lotsekeka;

Makhalidwe a valavu yothandizira molunjika
1. Kuyankha mofulumira: valve yothandizira mwachindunji imatengera mfundo ya kupanikizika, yomwe imatha kuyankha mwamsanga kusintha kwa zochitika;
2. Otetezeka komanso odalirika: valve yothandizira mwachindunji imathanso kugwira ntchito mokhazikika mkati mwazitsulo zazikulu, zomwe zingateteze bwino chitetezo cha dongosolo;
3. Kukonzekera kosavuta: valavu yothandizira mwachindunji imangofunika kuyesedwa nthawi zonse, palibe kusinthidwa nthawi zonse kwa ziwalo zomwe zimafunika, ndipo kukonza kumakhala kosavuta;
4. Phokoso laling'ono: Valavu yothandizira molunjika imatengera mfundo yoyendetsera bwino, kuwongolera kutseka kumakhala kofatsa, kumatha kuchepetsa phokoso, koyenera malo aphokoso.
