Ama-Full Port vs Reduced Port Ball Valve: Umehluko Obalulekile kanye Nomhlahlandlela Wokukhetha
Ama-valve ebhola ayizingxenye ezibalulekile ezinhlelweni zokulawula uketshezi, ahlukaniswe ngezinhlobo ezimbili eziyinhloko: i-full port (i-full bore) kanye ne-reduced port (i-reduced bore). Ukuqonda umehluko wawo kuqinisekisa ukusebenza kahle kanye nokusebenza kahle kwezindleko ezisetshenziswayo ezimbonini.
Ukuchaza Ama-Full Port vs Ama-Reduced Port Ball Valve
-I-Port Ball Valve Egcwele: Ububanzi bangaphakathi bevalvu bufana nobubanzi obungu-≥95% bobubanzi obujwayelekile bephayiphi (isb., ivalvu engamasentimitha angu-2 inomzila wokugeleza ongu-50mm).
Amathiphu: Uma ukhetha ivalvu yebhola, ivalvu yebhola engu-2 Inch egcwele igcwele inosayizi wevalvu obhalwe njenge-NPS 2.
- I-Valve Yebhola Lembobo Encishisiwe: Ububanzi bangaphakathi buyi-≤85% yobubanzi obujwayelekile bombhobho (isb., ivalvu engamasentimitha angu-2 inomzila wokugeleza ongu-~38mm).
Icebiso: Uma ukhetha ivalvu yebhola, ivalvu yebhola engu-2 Inch encishisiwe inosayizi wevalvu obhalwe njenge-NPS 2 x 1-1/2.
Umehluko Obalulekile Wesakhiwo
| Isici | I-Bore Ball Valve Egcwele | I-Valve Yebhola Elincishisiwe |
|---|---|---|
| Umklamo Wendlela Yokugeleza | Ilingana nobubanzi bombhobho; akukho ukuncishiswa | Amasayizi angu-1-2 amancane kunepayipi |
| Ukusebenza Kahle Kokugeleza | Ukuvinjelwa kokugeleza okungenalutho; ukwehla okuncane kwengcindezi | Ukumelana okuphezulu kune-full bore |
| Usayizi Wevalvu (i-NPS) | Umugqa wepayipi ohambisanayo (isb., i-NPS 2) | Kusho ukunciphisa (isb., i-NPS 2 × 1½) |
| Isisindo Nokubumbana | Ukwakhiwa okunzima; okuqinile | 30% elula; umklamo ogcina isikhala |
Ukuqhathaniswa Kokusebenza Nokusetshenziswa
| Isici | I-Bore Ball Valve Egcwele | I-Valve Yebhola Elincishisiwe |
|---|---|---|
| Imidiya Efanelekile | Uketshezi oluqinile (uwoyela ongahluziwe, udoti), izinhlelo zokugaya ingulube | Amagesi, amanzi, uketshezi olune-viscosity ephansi |
| Izidingo Zokugeleza | Ukugeleza okuphezulu kakhulu okunokumelana okuncane | Ukugeleza okulawulwayo; umthamo olungisekayo |
| Amacala Okusetshenziswa Okuvamile | Amapayipi amakhulu (uwoyela/igesi), izinhlelo zokuhlanza | Imigqa yamagatsha, amaphrojekthi athinta isabelomali |
| Ukwehla Kwengcindezi | Ukumelana okucishe kube yi-zero; kulungele amapayipi amade | Ukwehla kwengcindezi yendawo okuphezulu |
| Ukusebenza Kahle Kwezindleko | Izindleko eziphezulu kusengaphambili | Izindleko eziphansi ngo-30%; umthwalo wepayipi oncishisiwe |
Indlela Yokukhetha I-Ball Valve Efanele
Beka phambili i-Full Bore Uma:
1. Ukuphatha imidiya egobile/ethambile noma okudinga ukugoqwa.
2. Uhlelo ludinga ukugeleza okuphezulu kakhulu ngokulahlekelwa okuncane kwengcindezi.
3. Ukuhlanza/ukulungisa amapayipi kuyinto evamile.
Khetha i-Reduced Bore Uma:
1. Ukusebenza ngamagesi noma uketshezi olune-viscosity ephansi.
2. Kunemingcele yesabelomali; amavalvu alula ayathandwa.
3. Ukulawulwa kokugeleza kwamanzi kanye nokwenza ngcono isikhala kubaluleke kakhulu.
Kungani Kubalulekile
1. Ama-Full Bore Valves aqeda imikhawulo yokugeleza, anciphise izindleko zamandla ekuthuthweni okude.
2. Ama-Bore Valve Ancishisiwe anikeza ukonga izindleko (kufika ku-1/3 eshibhile) kanye nokulawula ukugeleza okusebenzayo kwezinhlelo ezihlangene, kuyilapho kunciphisa umthwalo wesakhiwo emapayipini.
