Chogulitsacho chimagwiritsidwa ntchito pagawo la AP1000 ngati chida chokokera mphamvu kuti chiteteze kutsika kwake kocheperako kuti zisawononge zida.
1.Ndi masika amtundu wa vacuum decompression, vacuum breaking valve imakhala ndi kupanikizika kosalekeza kosalekeza ndikukonza ndi kukhazikitsa kosavuta. Valavuyi imapangidwa molingana ndi mulingo wa kukakamiza ndipo kukakamiza kwake kumakulirakulira kuposa kukakamiza kwake kogwirira ntchito pansi pa kutentha kwa chilengedwe. Pakatikati pa valve ndikutsegula ndi kutseka gawo la valavu ndipo mphete yosindikizira ya O-mtundu imayikidwa mumphuno ya valve core kuti ikhale gawo losindikiza lapakati pa valve. Pamene valavu zisindikizo, O-mtundu chisindikizo mphete kulankhula kusindikiza pamwamba pa mpando valavu; pamene valavu kudumpha ndi kutulutsa, O-mtundu chisindikizo mphete amasiya kusindikiza pamwamba pa mpando valavu. Pamene phokoso la valve likuwomba mmbuyo, kasupe amatambasula ndi kutsegula ndi kutseka mbali kumapita mmwamba pa bowo lotsogolera la mpando wa valve; pamene pachimake valavu chitsegukira, kasupe compresses ndi kutsegula ndi kutseka gawo amapita pansi pa bowo lotsogolera mpando valavu.
2.The vacuum breaking valve, valve automatic, safuna galimoto yowonjezera ikagwiritsidwa ntchito. Pa nthawi yogwira ntchito bwino, mphamvu yolumikizana ya masika ndi sing'anga yomwe imagwiritsidwa ntchito pa diski ya valve imakankhira valavu yopita kumpando wa valve kuti malo osindikizira amamatire ndi kusindikiza; pamene kuthamanga kwapakati kutsika kufika pamtengo wa vacuum (mwachitsanzo, kupanikizika koipa mpaka kukakamiza), kasupe amakanikizidwa, valve disc imasiya mpando wa valve, mpweya wakunja umalowa ndikuwonjezera mphamvu; Pamene kupanikizika kwa dongosolo kumakwera kufika pamtengo wogwirira ntchito, kasupe amakoka chimbale cha valve kumpando wa valve ndi kusindikiza pamwamba kumamatira kachiwiri kuti abwerere kuntchito yabwino.
