Madzi obowolera amatha kuyenda momasuka kudzera mu valavu ya kelly popanda kutsika kwa mphamvu. Gwiritsani ntchito wrench yapadera kuti muyitembenuze 90° malinga ndi malangizo kuti muyatse ndi kuzimitsa.

2. Kapangidwe ka valavu ya Kelly ndi mfundo yogwirira ntchito

Valavu ya kelly yapamwamba ndi yapansi imapangidwa ndi thupi, mpando wa mpira wapansi, kasupe, kiyi yogwirira ntchito, valavu ya mpira, mphete yotsegulira yosungira, mpando wa mpira wapamwamba, chikwama chosungira mphete, mphete yosungira yotanuka ndi chisindikizo, wrench yowonjezera, ndi zina zotero. Mfundo yotsekera ndi yakuti kasupe amathandizira mpando wa mpira kuti ayike mpirawo ndikupangitsa kuti ukhale ndi katundu winawake. Mpirawo ndi chisindikizo cha mpando wa mpira zimakhala pafupi. Mpirawo ukatulutsidwa, maso a madzi satsekedwa. Ukatsekedwa, pamwamba pake pamakhala maso onse a madzi. Kupanikizika kwa mkati mwa annulus kumagwira ntchito pa mpirawo, zomwe zimapangitsa kuti mpirawo ndi mpando wa mpirawo ukhale wotsekeka kwambiri.

3. Momwe mungagwiritsire ntchito valavu ya kelly

(1) Musanagwiritse ntchito, gwiritsani ntchito wrench yapadera kuti muzungulire kiyi yogwirira ntchito kuti muwone ngati ingazungulire mosinthasintha, pamalo pake kapena pamalo pake;

(2) Mukamaliza kulumikiza malekezero apamwamba ndi otsika a kelly, gwiritsani ntchito wrench kachiwiri kuti muyese kusinthasintha kwa makiyi ogwiritsira ntchito musanatsike m'chitsime;

(3) Pamene kelly yaphulika kapena kuphulika kwachitika m'chitsime, valavu ya pulagi ya pamwamba kapena pansi ya kelly iyenera kutsekedwa pamalo apafupi;

(4) Pa nthawi ya ntchito yanthawi zonse, tsekani valavu ya pulagi yapansi musanatulutse kelly kuti madzi obowola asatulukire pansi pa bowolo;

(5) Limbikirani kutsegula ndi kutseka makoko apamwamba ndi apansi a kelly nthawi zonse. Mwachitsanzo, polumikiza chidutswa chimodzi kapena kugwiritsa ntchito makoko apamwamba ndi apansi a kelly nthawi ndi nthawi, kuti mupewe dzimbiri komanso kuti musamatsegule ndi kutseka bwino;

(6) Mukamaliza kulumikiza chidutswa chimodzi, valavu yotsekedwa ya pulagi iyenera kutsegulidwa nthawi yake kuti isagwire pampu poyambitsa pampu;

(7) Cholumikizira cha valavu chiyenera kuyikidwa kutali ndi mutu wa chitsime kuti chisagwere m'chitsime kapena kutayika;

(8) Mukasankha valavu yolumikizira, onetsetsani kuti mphamvu yake yogwira ntchito ikugwirizana ndi kuchuluka kwa mphamvu ya gulu loletsa kuphulika kwa chitsime.
