Mfundo yosankha yonse ya owongolera ochepetsa kupanikizika

Chowongolera chochepetsa kupanikizika ndi valavu yomwe imachepetsa kupanikizika kolowera ku mphamvu inayake yotulutsira mpweya posintha, ndipo imadalira mphamvu ya cholumikiziracho kuti chizisunga kupanikizika kotulutsira mpweya kukhala kokhazikika zokha.

Kusinthasintha kwa kuthamanga kwa mpweya wolowera mu valavu yochepetsera kuthamanga kuyenera kulamulidwa mkati mwa 80% - 105% ya mtengo woperekedwa wa kuthamanga kwa mpweya wolowera. Ngati kupitirira malire awa, magwiridwe antchito avalavu yochepetsera kupanikizikazidzakhudzidwa.

1. Kawirikawiri, kuthamanga kwa pansi pa madzi pambuyo pochepetsa sikuyenera kupitirira nthawi 0.5 ya kuthamanga kwa pamwamba pa madzi

2. Kasupe wa giya iliyonse ya valavu yochepetsera kupanikizika imagwiritsidwa ntchito kokha mkati mwa kuchuluka kwa kupanikizika komwe kumatuluka, ndipo kasupeyo iyenera kusinthidwa ngati ili pamwamba pa kuchuluka komwe ingagwiritsidwe ntchito.

3. Pamene kutentha kwa zinthu zoyatsira mpweya kuli kwakukulu, valavu yothandizira oyendetsa ndege kapena valavu yotsekedwa ndi woyendetsa ndege iyenera kusankhidwa nthawi zambiri.

4. Ngati cholumikiziracho chili mpweya kapena madzi, valavu ya diaphragm kapena valavu yothandizira oyendetsa ndege iyenera kusankhidwa.

5. Pamene cholumikiziracho chili ndi nthunzi, valavu yothandiza oyendetsa ndege kapena valavu yotsekedwa ndi bellows iyenera kusankhidwa.

6. Valavu yothandizira kupanikizika iyenera kuyikidwa m'mapaipi opingasa kuti ntchito, kusintha ndi kukonza zikhale zosavuta.

Malinga ndi zofunikira pakugwiritsa ntchito, mtundu ndi kulondola kwa valavu yowongolera kuthamanga kwa magazi zimasankhidwa, ndipo m'mimba mwake mwa valavuyo mumasankhidwa malinga ndi kuchuluka kwa mpweya womwe umatulutsa. Podziwa kuchuluka kwa mpweya womwe umabwera chifukwa cha valavuyo, iyenera kukhala yayikulu kuposa kuchuluka kwa mpweya womwe umatulutsa wa 0.1MPa. Vavu yochepetsera kuthamanga kwa magazi nthawi zambiri imayikidwa pambuyo pa cholekanitsa madzi, isanalowe mafuta kapena chipangizo chokhazikitsira, ndipo samalani kuti musalumikize cholowera ndi chotulukira cha valavuyo mobwerera m'mbuyo; valavuyo ikagwiritsidwa ntchito, chogwiriracho chiyenera kumasulidwa kuti chipewe kuti diaphragm nthawi zambiri isinthe mphamvu yake ndikusokoneza magwiridwe antchito ake.
