Eli nqaku liphonononga imigangatho yehlabathi kunye nokuvunywa kokuhlelwa kweevalvu zasemanzini ekufuneka zihlangabezane nako, ukubaluleka kweziqinisekiso, kunye nendlelaI-Qingdao I-FLOW, umntu othembekileyoumenzi weevalvu zaselwandle, iqinisekisa iimveliso ezisemgangathweni ophezulu neziqinisekisiweyo zeenqanawa kunye nezicelo zaselwandle.
Kutheni iMigangatho ibalulekile kwiiValve zaseLwandle
Iivalvu ezingathobeli imithetho zinokubangela ukungasebenzi kakuhle kwenkqubo, ukwaphulwa komthetho okusingqongileyo, kunye nexesha elibi lokungasebenzi ngexesha lokuhlolwa okanye uphicotho-zincwadi.Iindawo zaselwandle zibeka iivalvu emanzini anetyuwa emngxunyeni, uxinzelelo olugqithisileyo, ukungcangcazela, nokusebenza rhoqo. Ukusebenzisa iivalvu zaselwandle ezihlangabezana nemigangatho yamazwe ngamazwe kunceda ukuqinisekisa ukuba:
-
①Ukhuseleko lwabasebenzi, imithwalo, kunye neenqanawa
-
②Ukuthobela imithetho yezelwandle yamazwe ngamazwe
-
③Ubomi bemveliso obude kunye nokugcinwa okuncinci
-
④Ukuhlolwa kokuhlelwa okugudileyo kunye nokuvunywa kweechweba
Imigangatho ephambili kunye neziqinisekiso zeeValve zoLwandle
1. Izikhokelo ze-International Maritime Organisation (IMO)
Nangona i-IMO ingaqinisekisi ngokuthe ngqo iivalvu, ibeka isakhelo solawulo lokhuseleko lwaselwandle lwehlabathi kunye nokukhuselwa kwendalo. Imigaqo ye-IMO efana ne-SOLAS (Ukhuseleko lobomi elwandle) kunye ne-MARPOL zichaphazela ngokungathanga ngqo iimfuno zeevalvu, ngakumbi kwezi:Ulawulo lwamanzi oluyi-ballast.Iinkqubo zokukhusela umlilo.Ukhuseleko lwenkqubo yepetroli kunye nolawulo lokuvala
2. Iimvume zoMbutho woHlelo (Ngokwelizwe)
Uninzi lweevalvu zeenqanawa kufuneka ziqinisekiswe yimibutho yokwahlulahlula ukuqinisekisa ukuba ziyahlangabezana nemigangatho yokusebenza koomatshini, izinto, kunye noxinzelelo. Imibutho yokwahlulahlula ephambili ibandakanya:
| Uluntu | Ilizwe |
|---|---|
| I-DNV (Det Norske Veritas) | Norowe |
| I-ABS (i-American Bureau of Shipping) | Amazwe Amanyene |
| LR (Irejista kaLloyd) | Iunited kingdom |
| I-BV (iBureau Veritas) | Fransi |
| I-CCS (uMbutho woHlelo lwaseTshayina) | iTshayina |
| I-KR (iRejista yaseKorea) | Khoriya eseMzantsi |
| RINA (Registro Italiano Navale) | ElamaTaliyane |
| I-RS (iRejista yoLwandle lwaseRashiya) | Rhashiya |
| NK (Nippon Kaiji Kyokai) | Japhan |
3. Imigangatho ye-ISO yeeValve zoLwandle
I-International Organisation for Standardization (ISO) ichaza imigangatho eyahlukeneyo yehlabathi yokwenziwa, ukuvavanywa, kunye nokusebenza kweevalvu zoshishino nezolwandle:
| Umgangatho we-ISO | Inkcazo |
|---|---|
| I-ISO 10497 | Uvavanyo lomlilo lweevalvu |
| I-ISO 5208 | Uvavanyo loxinzelelo lweevalvu zesinyithi |
| I-ISO 15761 | Iglobhu yentsimbi, isango, kunye neevalvu zokujonga ezisetyenziselwa imizi-mveliso |
| I-ISO 5752 | Ubukhulu bevalvu yobuso ngobuso |
| I-ISO 9001 | Iinkqubo zolawulo lomgangatho zabavelisi |
4. Imigangatho ye-API (i-American Petroleum Institute)
-
I-API 598– Ukuhlolwa kwevalvu kunye novavanyo loxinzelelo
-
I-API 607– Uvavanyo lomlilo kwiivalvu ezijika ikota (kubalulekile kwiivalvu zebhola kunye neebhabhathane)
-
I-API 6D– Iivalvu zemibhobho kunye neenkqubo kwiinkqubo zeoyile negesi
Imigangatho yezinto zokwakha kunye nokwakha
Ngenxa yokuba iivalvu zasemanzini zijongene namanzi anetyuwa, iihydrocarbons, kunye neekhemikhali, izixhobo zazo zokwakha kufuneka zihambelane nokumelana nokugqwala kunye novavanyo loxinzelelo.
-

-
②ASTM B62 – Izixhobo zevalvu yobhedu
-
③EN 1982 – Iintsimbi ze-copper alloy valve castings zaseYurophu
-
④DIN & JIS – Imigangatho eqhelekileyo yaseJamani naseJapan esetyenziswa ekwakheni iilwandle
Iimfuno zoVavanyo lweeValve kunye noHlolo
-
①Uvavanyo loxinzelelo lomzimba kunye nesihlalo olusebenzisa i-hydrostatic
-
②Uvavanyo olukhuselekileyo emlilweni kwiinkqubo zepetroli neoyile
