IiValve zeBhalbhu eziGcweleyo: Imigaqo yoYilo, iiBalo, kunye nezicelo zeShishini
Ububanzi betshaneli yokuhamba kwevalvu yebhola yinto ebalulekileyo yokusebenza.iivalvu zebhola zezibuko ezipheleleyo, olu luhlu luchaza ukusebenza kakuhle kokuhamba kwamanzi, ukulahleka koxinzelelo, kunye nokufaneleka kwamashishini afunwa kakhulu. Nantsi indlela yokuyila kunye nokuyisebenzisa ngokufanelekileyo.
I-Full Port Ball Valve: Inkcazo kunye neendlela zokubala
1. Inkcazo engundoqo
Ivalvu yebhola ye-full port (full bore) inobubanzi bomjelo wokuhamba ohambelana ne-≥95% yobubanzi bangaphakathi bombhobho, nto leyo evumela ukuhamba okukhawulezileyo okunokwehla koxinzelelo oluncinci.
2. Ubalo olusekelwe kwiMfudlana
Sebenzisa ifomula ye-empirical fluid dynamics:
Q = K × Cv × √ΔP
Q: Izinga lokuhamba kwamanzi (GPM okanye m³/h)
K: Into yokulungisa (ngesiqhelo yi-0.9)
I-Cv: I-flow coefficient (ekhethekileyo kwi-valve)
ΔP: Umahluko woxinzelelo (psi okanye ibha)
Ifomula yobubanzi bembobo efunyenweyo:
d = (Q / (0.9 × Cv × √ΔP)) × 25.4
(d = ububanzi kwi-mm; 25.4 = ukuguqulwa kwe-intshi-mm)
3. Indlela emfutshane yobungakanani bepayipi
d = D × 0.8
d: Ububanzi bevalvu
D: Ububanzi obungaphandle bombhobho
Umzekelo: Kwipayipi ye-OD eyi-100mm, khetha ivalvu enembobo eyi-≥80mm.
Izibuko elipheleleyo vs Ukunciphisa izibukoUmahluko obalulekileyo
Ipharamitha | I-Valve yeBhola yePort epheleleyo | Yehlisa iValve yeBhalbhu yePort |
|---|---|---|
| Itshaneli Yokuhamba | I-ID yombhobho ohambelanayo (umz., DN50 = 50mm) | Iisayizi ezi-1-2 ezincinci (umz., DN50 ≈ 38mm) |
| Ukusebenza kakuhle kokuhamba kwamanzi | Ukumelana okuphantse kube yi-zero; ukuhamba ngokupheleleyo | Ukuncipha kokuhamba kwamanzi nge-15-30% |
| Ukwehla koxinzelelo | Ayinamsebenzi | Ibalulekile xa kukho amanzi amaninzi |
| Izicelo | Kubalulekile ekugayeni ihagu, ulwelo oluqinileyo | Iinkqubo ezihamba kancinci; iiprojekthi ezixabisa kancinci |
Ingcaciso ephambili:
Ivalvu ye-DN50 egcweleyo igcina ukuhamba kwe-50mm, ngelixa ivalvu ye-DN50 ye-reduce port inciphisa ukuhamba kwe-~DN40 (38mm) - ilahleko yendawo yokuhamba kwe-24%.
Izicelo Zemizi-mveliso: Apho iFull Port Valves Excel
1. Iipayipi zeoyile negesi
Umsebenzi:Ukuvala/ukulawula umgca wesiqu
Inzuzo:Ivumela ukugoba ngemibhobho ukuze kugcinwe ulusu; iphatha ioyile eluhlaza/udaka ngaphandle kokuyivala.
2. Ukucubungula iikhemikhali
Ityala Lokusetyenziswa:Imigca yokutya ye-reactor ehamba ngamandla
Inzuzo:Ithintela imida yokuhamba kwamanzi ephazamisa ukuqhubeka kwemveliso.
3. Ulawulo lwaManzi
Izicelo:
1. Iipayipi zamanzi zikamasipala
2. Iindawo zokungena/zokuphuma kwizityalo zokucoca amanzi amdaka
Kutheni: Iphucula ukuhamba kwamanzi ngamaxesha emfuno ephezulu.
Izikhokelo Zokukhetha: Ixesha Lokukhetha Izibuko Elipheleleyo
Khetha iivalvu zezibuko ezipheleleyo xa:
1.Ukuhamba kwamanzi kubalulekile:Iinkqubo ezifuna ukulahleka koxinzelelo oluncinci (umz., imibhobho yomgama omde).
2. Imidiya inzima: Ulwelo oluqinileyo, izinto ezicociweyo, okanye iinkqubo ezicocwayo.
3. Ukukhusela ikamva: Iiprojekthi ezilindele ukunyuka kwesantya sokuhamba kwamanzi.
Ukuqwalaselwa kweendleko:
Iivalvu zezibuko ezipheleleyo zibiza ngaphezulu kwama-20-30% kunezo zinciphisa izibuko kodwa zinciphisa ukusetyenziswa kwamandla ukuya kuthi ga kwi-15% kwiinkqubo ezihamba ngamanzi amaninzi.
