Iyini Indima Yama-Mud Gate Valve?

Amavalvu esango lodakaZisetshenziswa kakhulu ekubholeni uwoyela, ekufakeni usimende, kanye nasemisebenzini yokusebenza ukulawula ukugeleza kodaka lokubhoboza olunomfutho ophezulu noma olunye uketshezi olunemigodi. Imisebenzi yazo eyinhloko ihlanganisa:

1.Ukuvala Ukugeleza

Hlukanisa ngokusheshaimigqa yokujikeleza kodaka ngesikhathi sezimo eziphuthumayo noma ukulungiswa ukuze kuvinjelwe ukuqhuma noma ukuvuza.

Isibonelo: “Vula ivalvu yodaka ngokushesha uma kutholakala izimpawu zokukhahlela emthonjeni.”

2.Ukunciphisa Ingcindezi

Ukubekezelela ukucindezeleka okukhulu koketshezi lokubhoboza (ngokuvamileI-PSI engaphezu kuka-15,000) ukuze kugcinwe ubuqotho bokulawula umthombo.

3.Ukumelana Nokuguguleka/Ukugqwala

Imizimba yamavalvu kanye nezimbozo (isb., i-tungsten carbide) zimelana nokuguguleka okuvela odakeni olugcwele isihlabathi noma olubolayo.

4.Ukuhlanganiswa Kwesistimu ye-BOP

Sebenza njengezingxenye ezisizayo zokuvimbela ukuqhuma (BOPs) ukuze kuthuthukiswe ukuphepha kwekhanda lemithombo.

5.I-Valve yeSango LodakaAmapharamitha Okukhetha Ubuchwepheshe

1. Imininingwane Eyinhloko

Usayizi Wembobo:
Ububanzi obujwayelekile: 2″ kuya ku-12″ (Osayizi abavamile: 4″/6″/8″)

Isilinganiso Sokucindezela:
Ingcindezi yokusebenza: 5,000-15,000 PSI (Izilinganiso eziphezulu ziyatholakala)
Ihambisana namazinga e-API 6A/API 16C/ASME B16.34

2.Izinhlobo Zokuxhumana

I-Flanged:
I-ASME B16.5 (RF/RTJ)
I-API 6A (6B/6BX)

Kuboshwe:
I-API 6A (6B/6BX)

Okunentambo:
I-API 7-1 (Umcu Oyinhloko)
I-NPT (Intambo Yepayipi Ejwayelekile YaseMelika)

3.Imininingwane Yezinto Ezibalulekile

Izinto Zomzimba:
Insimbi Yekhabhoni (ASTM A216 WCB)
Insimbi Engagqwali (ASTM A351 CF8M)
Insimbi Ephindwe Kabili (ASTM A995 4A/5A)

Izinhlelo Zokuvala:
Insimbi ibe yinsimbi (i-Tungsten Carbide/i-Stellite)
Izisimbozo Eziqinile (NBR/FKM)

4. Izidingo Zesevisi Ekhethekile

Isevisi Engacacile (H₂S/CO₂):
Ihambisana ne-NACE MR0175/ISO 15156

Izinga Lokushisa Eliphakeme Kakhulu:
Izinga lokushisa eliphansi: -50°C (-58°F)
Izinga lokushisa eliphezulu: 232°C (450°F) noma ngokwezifiso

Ukuphathwa Kwemidiya Ehlukunyezwayo:
Izihlalo/amasango anobuso obuqinile ayatholakala

5. Iziqondiso Zokukhetha:Sicela unikeze okulandelayo ukuze ukhethe ivalvu ngokunembile:

Uhlobo Lomthombo:[Umhlaba/Ogwini/I-Shale/Amanzi Ajulile]

Ukucindezela Okuphezulu:[_____ i-PSI]

Izici Zoketshezi:[Okuqukethwe kwesihlabathi, ukuhlushwa kwe-Cl⁻, amazinga e-H₂S]

Izici Zemvelo:[Izimfuneko zokushisa, ukugqwala, ukumelana nokuqhuma]
