Momwe valavu ya chipata imagwirira ntchito

Thevalavu ya chipatandi chipata chotsegulira ndi kutseka. Njira yoyendetsera chipata ndi yolunjika ku mbali ya madzi. Valavu ya chipata imatha kutsegulidwa kwathunthu ndikutsekedwa kwathunthu, ndipo singathe kusinthidwa kapena kukanda. Valavu ya chipata imatsekedwa ndi kukhudzana pakati pa mpando wa valavu ndi mbale ya chipata. Nthawi zambiri, pamwamba pa chitseko padzakhala ndi zinthu zachitsulo kuti ziwonjezere kukana kuwonongeka, monga pamwamba pa 1Cr13, STL6, chitsulo chosapanga dzimbiri, ndi zina zotero. Chipata chili ndi chipata cholimba ndi chipata chotanuka. Malinga ndi zipata zosiyanasiyana, valavu ya chipata imagawidwa kukhala valavu ya chipata cholimba ndi valavu ya chipata chotanuka.

Gawo lotsegula ndi kutseka la valavu ya chipata ndi chipata, ndipo kayendetsedwe ka chipata ndi kolunjika ku mbali ya madzi.valavu ya chipataIkhoza kutsegulidwa kwathunthu ndi kutsekedwa kwathunthu, ndipo singathe kusinthidwa kapena kupotozedwa. Chipata chili ndi malo awiri otsekera. Malo awiri otsekera a valavu ya chipata yomwe imagwiritsidwa ntchito kwambiri imapanga mawonekedwe a wedge. Ngodya ya wedge imasiyana malinga ndi magawo a valavu, nthawi zambiri 5°, ndi 2°52' pamene kutentha kwapakati sikuli kokwera. Chipata cha valavu ya chipata cha wedge chingapangidwe kukhala chonse, chotchedwa chipata cholimba; chingapangidwenso kukhala chipata chomwe chingapangitse kusintha pang'ono kuti chiwongolere luso lake ndikupangitsa kuti ngodya ya pamwamba pa sealing isinthe panthawi yokonza. Mbaleyo imatchedwa chipata chotanuka. Vavu ya chipata ikatsekedwa, pamwamba pa sealing imatha kutsekedwa ndi kupanikizika kwapakati, ndiko kuti, kudalira kukakamiza kwapakati kuti ikanikizire pamwamba pa chipata kupita ku mpando wa valavu mbali inayo kuti zitsimikizire kutseka kwa pamwamba pa sealing, komwe kumadzitsekera. Mavavu ambiri a chipata amatsekedwa mwamphamvu, ndiko kuti, valavu ikatsekedwa, chipata chiyenera kukakamizidwa motsutsana ndi mpando wa valavu ndi mphamvu yakunja kuti zitsimikizire kulimba kwa pamwamba pa sealing. Chipata cha valavu ya chipata chimayenda molunjika ndi tsinde la valavu, lomwe limatchedwa valavu ya chipata chokweza, lomwe limadziwikanso kuti valavu ya chipata chokwera. Nthawi zambiri, pamakhala ulusi wa trapezoidal pa ndodo yokweza. Kudzera mu nati pamwamba pa valavu ndi groove yotsogolera pa thupi la valavu, kuyenda kozungulira kumasinthidwa kukhala kuyenda kolunjika, ndiko kuti, mphamvu yogwirira ntchito imasinthidwa kukhala kugwedezeka kogwirira ntchito. Vavu ikatsegulidwa, kutalika kwa chipata chokweza kuli kofanana ndi nthawi 1:1 kuposa kukula kwa valavu, njira yamadzimadzi imakhala yosatsekedwa, koma malo awa sangayang'aniridwe panthawi yogwira ntchito. Pakugwiritsa ntchito kwenikweni, nsonga ya tsinde la valavu imagwiritsidwa ntchito ngati chizindikiro, ndiko kuti, malo omwe sangatsegulidwe, ngati malo ake otseguka kwathunthu. Pofuna kuganizira za kutseka komwe kumachitika chifukwa cha kusintha kwa kutentha, nthawi zambiri imatsegulidwa pamalo apamwamba, kenako kubwerera ku 1/2-1 kutembenuka, ngati malo a valavu yotseguka kwathunthu. Chifukwa chake, malo otseguka kwathunthu a valavu amatsimikiziridwa malinga ndi malo a chipata, ndiko kuti, kukwapula. Kwa enamavavu a chipata, nati ya tsinde imayikidwa pa chipata, ndipo kuzungulira kwa gudumu lamanja kumayendetsa tsinde la valavu kuti lizungulire, zomwe zimapangitsa kuti chipata chikwere. Mtundu uwu wa valavu umatchedwa valavu ya tsinde lozungulira, kapena valavu ya tsinde lakuda.
