Ukuhlelwa kwengqiniba
1. Ngokwe-radius yayo ye-curvature, inokwahlulwa ibe yi-radius endeingqinibakunye nengqiniba yerediyasi emfutshane. I-elbow yeradius ende ithetha ukuba i-radius yayo yokugoba ilingana namaxesha angama-1.5 ububanzi obungaphandle bombhobho, oko kukuthi, R = 1.5D. Ingqiniba yeradiyasi emfutshane ithetha ukuba iradiyasi yayo yokugoba ilingana nedayamitha yangaphandle yombhobho, oko kukuthi, R=D. Kwifomula, i-D yi-diameter ye-elbow kwaye u-R yiradius ye-curvature. Elona ngqiniba lisetyenziswa kakhulu yi-1.5D. Ukuba ayiboniswanga kwikhontrakthi njenge-1D okanye i-1.5D, imigangatho yesigqeba esetyenziswa ngokuqhelekileyo e-China ukunyusa ukhetho lwe-1.5D yi-GB/T12459-2005, GB/T13401-2005, kunye ne-GB/T10752-1995
2. Ngokwesimo sesakhiwo, ngokuqhelekileyo i-elbow ejikelezayo, i-elbow square, njl.
Imilinganiselo efanelekileyo yengqiniba
Ngokubanzi, i-angle ye-elbow, i-radius yokugoba, ububanzi, ubukhulu bodonga kunye nezinto eziphathekayo zinokumiselwa kuphela emva kokwazi le datha ilandelayo.
Ukubalwa kobunzima bethiyori yengqiniba
1. I-elbow ejikelezayo: (i-diameter yangaphandle - ubukhulu bodonga) * ubukhulu bodonga * i-coefficient * 1.57 * i-diameter ye-nominal * i-coefficient eninzi: i-carbon steel: 0.02466
Intsimbi engatyiwa: 0.02491Ingxubevange 0.02483
90 ° ingqiniba (idayamitha yangaphandle - ubukhulu bodonga) * Ubukhulu bodonga * i-coefficient (0.02466 ye-carbon steel) * 1.57 * i-dimeter yegama * multiple/1000=ubunzima bethiyori ye-90 ° ingqiniba (kg)
2. Ingqiniba yesikwere:
1.57 * R * iperimeter yomlomo wesikwere * ubuninzi * ubukhulu
Ukubalwa kwendawo yengqiniba Ukuba ubunzima bubalwe, ungasebenzisa ubunzima / ukuxinana / ukutyeba ukubala indawo, kodwa nikela ingqalelo kumanyano lweeyunithi.
1. Ingqiniba engqukuva=1.57 * R * caliber * 3.14;
2. Ingqiniba yesikwere=1.57 * R * iperimeter yomlomo wesikwere
R imele iradiyasi egobayo, 90 ° indlela yokubala yengqiniba
