i-allen flat countersunk izikulufi zokuvala ikhanda
Incazelo
Eyethuizikulufo zokuvalaziwumkhiqizo omusha oklanyelwe ukumelana namanzi nothuli, futhi ukwakheka kwawo okuyingqayizivele nezinzuzo kuzenza zidume ezinhlobonhlobo eziningi zobunjiniyela nezinhlelo zokusebenza.
Okokuqala, yethuizikulufo ezingangeni manziyakhelwe ngama-hexagon countersunks, angenzi nje kuphelaizikulufukulula ukuyifaka, kodwa futhi inenzuzo ye-anti-twisting ukunikeza uxhumano oluqinile. Ifakwe ukusebenza kahle okuphezuluisikulufu somshini wokuvala uphawuama-gaskets ukuqinisekisa uphawu oluphelele ngesikhathi sokufakwa, ukuvimbela umswakama, uthuli nezinye izinto eziyingozicountersunk sealing screwsukungena ekuhlanganyeleni. Lesi sici sivumela izikulufu zokuvala ukuthi zingagcini nje ngokunikeza uxhumano oluqinile, kodwa futhi ukugcina uxhumano lomile futhi luhlanzekile ngaso sonke isikhathi.
Okwesibili, ezindaweni ezingaphandle noma ukuchayeka isikhathi eside kumswakama, okuvamileIsikulufu sokuvala esingangeni manziziyakwazi ukugqwala futhi zixege. Eyethuinsimbi engagqwali sealing ngezikulufoazikwazi ukumelana nokugqwala futhi zimelana nesimo sezulu, ngakho zigcina ukuxhumana okuphephile ngisho nasezimeni zangaphandle ezinzima. Kungakhathaliseki ukuthi ifenisha yangaphandle, izakhiwo zokwakha noma imishini yezimboni,isikulufa sokuvala sishisiweukuqinisekisa ukusebenza okuqinile nokuthembekile kwesikhathi eside.
Ekugcineni, wethuihexagon isikulufu esingangeni manzifuthi ihlinzeka ngomphumela omuhle kakhulu wokuhlobisa, futhi umklamo we-hexagon uwenza isicaba ngobuso ngemva kokufakwa futhi awonakali kalula. Ngesikhathi esifanayo, sinikeza ukucaciswa okuhlukahlukene kanye nezinketho zombala ukuhlangabezana nezitayela ezahlukene zokuhlobisa kanye nezidingo.
