Indlela Yokukhetha Ivalvu Yolwandle Efanelekileyo

Ukukhetha ivalvu yolwandle efanelekileyo kubalulekile ukuqinisekisa ukusebenza okukhuselekileyo, okusebenzayo, nokuthembekileyo kwiinqanawa nakwiinkqubo zaselunxwemeni. Ngeentlobo ezininzi zeevalvu kunye nokusetyenziswa kwazo kwishishini lolwandle - ukusuka kwiinkqubo ze-ballast ukuya kwiisekethe zokupholisa, imigca yepetroli, kunye nokukhuselwa komlilo - ukwenza ukhetho olufanelekileyo kuxhomekeke kwizinto ezininzi ezibalulekileyo.

1. Qonda iSicelo kunye neMedium

Yonke inkqubo yolwandle iphatha uhlobo oluthile lolwelo (amanzi, ioyile, ipetroli, umphunga, njl.njl.) kwiingcinezelo ezahlukeneyo, amaqondo obushushu, kunye namazinga okuhamba kwamanzi.

Zibuze:

• ①Luhlobo luni lwesixhobo esihamba ngevalvu? (umz., amanzi olwandle, amanzi acocekileyo, ioyile, amafutha, igesi, umphunga)

• ②Ngaba le iphakathi iyabola, iqinile, okanye iyatsha?

• ③Ingaba yinkqubo yokhuseleko ebalulekileyo (umz., ukucima umlilo, ukucima ipetroli, ukucima ipetroli)?

Ingcebiso:Kwinkqubo ezirhabaxa okanye ezisebenzisa amanzi anetyuwa, khethaubhedu, ubheduokanyeiivalvu zentsimbi engatyiwayo.

2. Khetha Uhlobo lweValve olufanelekileyo

3. Cinga ngokuhambelana kwezinto

Iindawo zaselwandle zifuna izinto ezikwaziyo ukumelana nokugqwala ngenxa yokuchatshazelwa rhoqo ngamanzi anetyuwa, ukufuma, kunye notshintsho lobushushu.

• ①Ibhronzi/Ibhrasi – Iyakwazi ukumelana nokugqwala, ixhaphakile kwiinkqubo zamanzi olwandle

• ②Intsimbi Engagqwaliyo – Ihlala ixesha elide kwaye iyamelana kakuhle, ilungele ulwelo olunoxinzelelo oluphezulu okanye oluneziqholo

• ③Intsimbi Ephosiweyo – Ixabiso layo liphantsi, kodwa ifanelekile kwiincindi ezingaboliyo kuphela

• ④Intsimbi yeDuplex/Super Duplex – Iialloy ezisebenza kakuhle kakhulu kwizicelo ezigqithisileyo

Ingcebiso:Soloko udibanisa izinto zevalvu nemibhobho kunye nendawo ephakathi ukuze uphephe ukubola kwe-galvanic.

4. Vavanya Uvavanyo Loxinzelelo kunye Nobushushu

• ①Jonga i-PN (Pressure Nominal) okanye iKlasi yovavanyo

• ②Qinisekisa uluhlu lobushushu bokusebenza

Iivalvu kufuneka zihlangabezane okanye zidlule kwiimfuno zenkqubo kwaye zihambelane nemigangatho yoluntu lokuhlelwa kwemigangatho.

5. Qinisekisa ukuba imibutho yoHlelo iyavunywa

Zonke iivalvu zolwandle kufuneka zihlangabezane nemigangatho yokhuseleko lolwandle lwamazwe ngamazwe kwaye zivunywe yiMibutho yoHlelo efanelekileyo, efana nale:I-DNV (eNorway).I-ABS (e-USA).BV (eFransi).Irejista kaLloyd (e-UK).I-CCS (eTshayina)

Ingcebiso:Qinisekisa ukuba umenzi unikezela ngamaxwebhu okuqinisekisa ivalvu nganye.

6. Khetha umenzi weevalvu zolwandle othembekileyo

Khetha umthengisi weevalvu zasemanzini onokuthi:

• ①Unamava eminyaka emininzi kushishino

• ②Ibonelela ngendlela yokwenza usetyenziso lwakho ngokwezifiso

• ③Ibonelela ngeevalvu eziqinisekisiweyo, ezivavanyiweyo, nezibhalwe phantsi

• ④Ixhasa inkonzo emva kokuthengisa kunye nokubonisana ngobuchwepheshe

I-Qingdao I-FLOWukhokelayoumenzi weevalvu zaselwandlengamava angaphezu kweminyaka eli-10. Sinikezela ngoluhlu olupheleleyo lweevalvu zasemanzini eziqinisekisiweyo, kuquka iivalvu zesango, iivalvu zeglobe, iivalvu zebhabhathane, iivalvu zokujonga, iivalvu zestorm, nokunye — sikhonza iinqanawa kumazwe angaphezu kwama-40 ngeziqinisekiso ze-CE, DNV, ABS, kunye ne-LR.
