Li-valve tsa Bolo ea Li-Port tse Felletseng: Melao-motheo ea Moralo, Lipalo, le Litšebeliso tsa Liindasteri
Bophara ba kanale ea phallo ea valve ea bolo ke ntlha ea bohlokoa ea ts'ebetso.li-valve tse felletseng tsa bolo ea koung, tekanyo ena e laola bokgoni ba phallo, tahlehelo ya kgatello, le ho tshwaneleha bakeng sa diindasteri tse batlwang haholo. Mona ke mokhoa wa ho di bopa le ho di sebedisa ka katleho.
Valve e Felletseng ea Ball ea Port: Tlhaloso le Mekhoa ea ho Bala
1. Tlhaloso ea Motheo
Valve ea bolo ea kou e felletseng (e tletseng mokoti) e na le bophara ba kanale ea phallo bo lekanang le ≥95% ea bophara ba ka hare ba phaephe, e nolofalletsang phallo e batlang e sa thibeloa ka ho theola khatello hanyane.
2. Palo e Thehiloeng ho Phallo
Sebelisa foromo ea matla a mokelikeli oa empirical:
Q = K × Cv × √ΔP
P: Sekhahla sa phallo (GPM kapa m³/h)
K: Ntlha ea tokiso (hangata 0.9)
Cv: Koefficient ea phallo (e ikhethileng ka valve)
ΔP: Phapang ea khatello (psi kapa bare)
Foromo ea bophara ba mokoti e nkiloeng:
d = (Q / (0.9 × Cv × √ΔP)) × 25.4
(d = bophara ka mm; 25.4 = phetoho ea lisenthimithara-mm)
3. Tsela e Khutšoanyane ea Boholo ba Liphaephe
d = D × 0.8
d: Bophara ba mokoti oa valve
D: Bophara ba kantle ba phaephe
Mohlala: Bakeng sa phaephe ea OD ea 100mm, khetha valve e nang le mokoti oa ≥80mm.
Kou e Felletseng khahlanong le Kou e FokotsangLiphapang tse Bohlokoa
Paramethara | Belofo e Felletseng ea Bolo ea Port | Fokotsa Valo ea Ball ea Port |
|---|---|---|
| Mokero oa Phallo | ID ea phaephe e bapisang (mohlala, DN50 = 50mm) | Tse nyane ka boholo bo le 1-2 (mohlala, DN50 ≈ 38mm) |
| Bokgoni ba Phallo | Khanyetso e batlang e le lefela; phallo e felletseng | Phokotso ea phallo ea 15-30% |
| Ho theoha ha Khatello | Ha e na thuso | E bohlokoa ka sekhahla se phahameng sa phallo |
| Likopo | Bohlokoa bakeng sa ho hohela kolobe, maro a viscous | Mekhoa ea phallo e tlase; merero e nang le litšenyehelo tse tlase |
Temohisiso ea Bohlokoa:
Valve e felletseng ea DN50 e boloka phallo ea 50mm, ha valve e fokotsoang ea DN50 e fokotsa phallo ho ~DN40 (38mm) - tahlehelo ea sebaka sa phallo ea 24%.
Likopo tsa Liindasteri: Moo Li-valve tsa Kou e Felletseng li Excel
1. Liphaephe tsa Oli le Khase
Mosebetsi:Ho koaloa/taolo ea mohala oa kutu
Molemo:E nolofalletsa ho kenya liphaephe bakeng sa tlhokomelo; e sebetsana le oli e tala/lerotholi ntle le ho thiba.
2. Ts'ebetso ea Lik'hemik'hale
Nyeoe ea Tšebeliso:Mela ea phepelo ea reactor e phallang ka bongata
Melemo:E thibela lithibelo tsa phallo tse sitisang ho tswela pele ha tlhahiso.
3. Tsamaiso ea Metsi
Likopo:
1. Metsi a phepelo ea metsi a masepala
2. Li-invest/li-outlet tsa fektheri ea kalafo ea metsi a litšila
Hobaneng: E eketsa phallo bakeng sa linako tsa tlhokeho e phahameng.
Tataiso ea Khetho: Nako ea ho Khetha Kou e Felletseng
Khetha li-valve tse felletseng tsa port ha:
1.Phallo e bohlokoa haholo:Mekhoa e hlokang tahlehelo e nyane ea khatello (mohlala, liphaephe tse tsamaeang sebaka se selelele).
2. Mecha ea litaba e thata: Metsi a viscous, marotholi, kapa litsamaiso tse hloekisoang.
3. Ho sireletsa bokamoso: Merero e lebelletseng keketseho ea sekhahla sa phallo.
Tlhokomelo ea Litšenyehelo:
Li-valve tsa port e felletseng li bitsa chelete e fetang 20-30% ho feta ho fokotsa port empa li fokotsa tšebeliso ea matla ka ho fihlela ho 15% lits'ebetsong tse phallang haholo.
