Li-valve tsa heke li ka sebelisoa bakeng sa maro a mangata.Li-valve tsa heke li loketse tlas'a maemo a latelang a ts'ebetso: Metsi a nooang, metsi a litšila le metsi a sa jeleng paate: mocheso o pakeng tsa -20 le +80 ℃, lebelo la phallo ea 5 m / s le khatello ea phapang ea bar e fihlang ho 16.
Tšebeliso: Belofo ea heke ea tiiso e bonolo e fihlella tiiso e fihlella ts'ebetso ea tiiso, e sebelisa matla a tsoang ho elastil sluice board, tima sehare, moo khatello ea ho sebetsa e leng ≤ 1 MPa, mocheso o sebetsang ke ≤ 8 ° C.Li sebelisoa haholo ho tsa meralo, linthong tse jeoang, meriana, matla a lik'hemik'hale, indasteri ea ho kenya le ho ntša metsi, joalo-joalo. Ho lokisa metsi a liphaephe le liphaephe tseo a li etsang le lisebelisoa.
Li-valve tsa heke tse nang le li-ductile iron resilient li etselitsoe ho fana ka ts'ebeletso e tšepahalang le e tšoarellang nako e telele lits'ebetsong tsa phepelo ea metsi le phepelo ea metsi.Li-valve tsena li entsoe ho latela Standard Standard BS5163 'me li loketse ho sebelisoa lits'ebetsong tse kaholimo le ka tlas'a lefatše.
'Mele oa valve o entsoe ka tšepe ea ductile, e leng thepa e matla le e tšoarellang e khonang ho mamella khatello e phahameng le mocheso.Sephahla se boetse se na le setulo se tsitsitseng, se fanang ka tiiso e tiileng le ho thibela ho lutla.Setulo se tsitsitseng se entsoe ka rabara ea EPDM kapa NBR, e hanyetsanang le ho bola le tlhaselo ea lik'hemik'hale.
Heke ea valve e etselitsoe ho tsamaea hantle le ha bonolo, ho fana ka torque e tlaase ea ho sebetsa le ho fokotsa kotsi ea tšenyo ea valve.Heke e boetse e koahetsoe ka epoxy ho fana ka tšireletso e eketsehileng khahlanong le ho bola.
Belofo e sebelisoa ho sebelisoa lebili la letsoho kapa lebokose la gear, le lumellang ho laola ho phalla ha metsi habonolo le ka nepo.Valve e ka kenngoa sebakeng leha e le sefe, e leng se etsang hore e loketse ho sebelisoa mefuteng e mengata ea lisebelisoa.
Ka kakaretso, li-valve tsa heke tse nang le ductile iron resilient ke tharollo e tšepahalang le e theko e tlaase bakeng sa phepelo ea metsi le lits'ebetso tsa phepelo ea metsi.Li bonolo ho li kenya, ho sebetsa le ho li hlokomela, 'me li fana ka litšebeletso tse tšoarellang nako e telele ka nako e fokolang.
