Yintoni Indima YeeValve Zesango Lodaka?

Iivalvu zesango lodakaZisetyenziswa kakhulu ekubholeni ioyile, ekufakeni isamente, nakwimisebenzi yokulungisa ukuze kulawulwe ukuhamba kodaka lokubhoboza olunoxinzelelo oluphezulu okanye olunye ulwelo olunemibhobho yamanzi. Imisebenzi yazo ephambili ibandakanya:

1.Ukuvalwa Kokuhamba Komoya

Yahlula ngokukhawulezaimibhobho yokujikeleza kodaka ngexesha leengxamiseko okanye ukulungiswa ukuze kuthintelwe ukuqhushumba okanye ukuvuza.

Umzekelo: “Vula ivalvu yodaka ngoko nangoko ukuba iimpawu zokukhaba kwequla zifunyenwe.”

2.Uxinzelelo oluphantsi

Ukumelana noxinzelelo olugqithisileyo lolwelo lokubhola (ngesiqheloI-PSI engaphezulu kwe-15,000) ukugcina ingqibelelo yolawulo lomngxuma.

3.Ukumelana nokukrala/nokugqwala

Imizimba yeevalvu kunye nezitywini (umz., i-tungsten carbide) ziyamelana nokukhukuliseka okuvela kudaka oluzaliswe yintlabathi okanye olubolayo.

4.Ukuhlanganiswa kweNkqubo yeBOP

Zisebenza njengezixhobo ezincedisayo zokuthintela ukuqhushumba (ii-BOP) ukuze kuphuculwe ukhuseleko lwentloko yemithombo.

5.Ivalvu yeSango lodakaIiparamitha zoKhetho loBugcisa

1. Iinkcukacha eziphambili

Ubungakanani beBore:
Uluhlu oluqhelekileyo: 2″ ukuya kwi-12″ (Ubungakanani obuqhelekileyo: 4″/6″/8″)

Uvavanyo loxinzelelo:
Uxinzelelo olusebenzayo: 5,000-15,000 PSI (Uvavanyo oluphezulu luyafumaneka)
Iyahambelana ne: imigangatho ye-API 6A/API 16C/ASME B16.34

2.Iintlobo zoQhagamshelo

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

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

Ifakwe imisonto:
I-API 7-1 (Umsonto oPhambili)
I-NPT (Umsonto wePipe oqhelekileyo waseMelika)

3.Iinkcukacha zezinto ezibonakalayo

Izinto Zomzimba:
Intsimbi yeCarbon (ASTM A216 WCB)
Intsimbi Engagqwaliyo (ASTM A351 CF8M)
Intsimbi yeDuplex (ASTM A995 4A/5A)

Iinkqubo zokutywina:
Isinyithi-ukusuka kwisinyithi (iTungsten Carbide/Stellite)
Izitywino Eziqinileyo (NBR/FKM)

4. Iimfuno zeNkonzo eKhethekileyo

Inkonzo emuncu (H₂S/CO₂):
I-NACE MR0175/ISO 15156 iyahambelana

Ubushushu Obugqithisileyo:
Ubushushu obuphantsi: -50°C (-58°F)
Ubushushu obuphezulu: 232°C (450°F) okanye ngokwezifiso

Ukuphathwa kweMidiya erhabaxa:
Izihlalo/amasango aqinileyo ayafumaneka

5. Izikhokelo zoKhetho:Nceda unikezele oku kulandelayo ukuze ukhethe ivalvu ngokuchanekileyo:

Uhlobo lomthombo:[Umhlaba/Olunxwemeni/I-Shale/Amanzi anzulu]

Uxinzelelo oluphezulu:[____ PSI]

Iimpawu zolwelo:[Umxholo wesanti, uxinaniso lweCl⁻, amanqanaba e-H₂S]

Izinto eziphathelele indalo:[Iimfuneko zobushushu, ukubola, ukuthintela ukuqhuma]
