Intsingiselo yeKlasi yokulinganisa i-B16 series flange: Ukulinganiswa kweklasi kubizwa ngokoxinzelelo oluvumelekileyo (8750PSI) lwe-A105, i-WCB 1.1 impahla yeqela phantsi kwe-454 ° C kunye noxinzelelo olusekelwe kwi-60.3MP:

• P1=(10S/8750)*Pr≤Pc

I-P1 - iqondo loxinzelelo lwe-flange kwiqondo lokushisa elihambelanayo, ibha.
S - ixabiso loxinzelelo oluvumelekileyo lwezinto eziphathekayo, i-MPa.
Pr - flange Ixabiso leClass.

I-PC - iBar yokulinganisa uxinzelelo oluphezulu.

Kwi-flange yezinto eziphathekayo 150 # kunye noxinzelelo oluvumelekileyo lwe-100MPa, iyafumaneka (10 * 100/8750) * 150 = 17Bar = 1.7MPa.Ilingana noxinzelelo oluvumelekileyo lwe-150 # i-flange, ingcinezelo yayo yokusebenza evumelekileyo yi-1.7%.

Iikhrayitheriya zokumisela indawo yeBolt ye-B16 yochungechunge lweflange:
Ukudibanisa i-flange okanye i-valve yomzimba:

• AB *7000Psi≥Ag*Pc-> AB *120MPa≥Ag*Pg

U-Ab - indawo enqamlezileyo yebholt
Ummandla we-Ag gasket umphezulu woqhagamshelwano ngaphakathi nangaphandle kwidayamitha (kubandakanywa indawo yokuthwala kwidayamitha ye-gasket yangaphakathi).
I-PC - Ibakala leklasi ye-flange
Umthamo wokuthwala webholithi awuyi kuba ngaphantsi kwengqikelelo yokuba uxinzelelo lwangaphakathi lungaphakathi kwidayamitha yangaphandle yendawo yokutywinwa kwe-gasket xa uxinzelelo oluvumelekileyo lulingana ne-120MPa.Uxhulumaniso lwe-flange, i-bolt ye-a193b7 enegunya lokuvunwa kwe-105ksi (724mpa) isetyenziswa ngokubanzi, kwaye i-factor yokhuseleko loyilo lwe-bolt yi-ns ≥ 6. Ngoko ke, indawo ye-bolt ye-ASME B16.5 i-flange inkulu kune-ASME VIII I non. -Flange eqhelekileyo.Ngenxa yesixa esikhulu sentshiyekela yebholiti, amandla eflange asoloko engafanelekanga xa kubalwa ngokwefomula.Kodwa enyanisweni, i-flange ikhuselekile, yingakho inkcazo ichaza ukuba i-flange ekhethiweyo ngokwemigangatho ye-flange ye-B16.5 ayinakubalwa ngokwefomula.

Intsingiselo ye-Sch: Sch: isifinyezo seshedyuli ye-umpers yobungakanani bombhobho.Kuthetha ukuba umlinganiselo woxinzelelo lwenkqubo yoyilo lwemibhobho kwizinto ezivumelekileyo zoxinzelelo kwiqondo lokushisa loyilo liphindaphindwa nge-100 0 kunye nexabiso emva kokujikeleza.Umzekelo, ukuba uxinzelelo loyilo yi-1MPa kunye noxinzelelo oluvumelekileyo lombhobho yi-100Mpa, umbhobho one-1/100 100 0=10 kunye> Sch.10 kufuneka isetyenziswe.Kwimibhobho ngokubanzi, uxinzelelo oluvumelekileyo lwezinto eziqhelekileyo malunga ne-100Mpa, i-Sch.80 inokuthwala i-8MPa, i-Sch.160 inokuthwala i-16MPa, njalo njalo, kukho ireferensi jikelele yokukhetha i-Sch efanelekileyo.
