Iivalvu zeBhola zeMetal ze-API 608: Imigangatho, usetyenziso, iimpawu

IUmgangatho we-API 608, eyasekwa yi-American Petroleum Institute (API), ilawula iinkcukacha zeevalvu zebhola zesinyithi ezijijekileyo, ezinemisonto, kunye nezijijelweyo. Yamkelwe ngokubanzi kwi-oyile, i-petrochemical, kunye nezicelo zemizi-mveliso, lo mgangatho uqinisekisa ukuthembeka kunye nokhuseleko lweevalvu ezisetyenziswa kwiinkqubo zemibhobho yenkqubo ye-ASME B31.3. Iivalvu ze-API 608 ziyafumaneka ngobukhulu obuqala kwi1/4 intshi ukuya kwi-24 intshikunye neeklasi zoxinzeleloI-150, 300, 600, kunye ne-800 PSI.

Iimfuno eziphambili ze-API 608 Standard

Umgangatho we-API 608 uchaza izikhokelo ezingqongqo zeuyilo, imveliso, uvavanyo, kunye nokuhlolwaiivalvu zebhola zesinyithi. Iinkcukacha eziphambili ziquka:

• Umgangatho woYilo: API 608
• Ubukhulu boQhagamshelo: ASME B16.5 (iiflanges)
• Ubukhulu Bobuso Ngobuso: ASME B16.10
• Imigangatho yoVavanyo: API 598 (uvavanyo loxinzelelo kunye nokuvuza)

Ezi mfuno ziqinisekisa ukuthotyelwa kwemilinganiselo yokhuseleko kunye nokusebenza kwiindawo ezinoxinzelelo oluphezulu kunye nobushushu obuphezulu.

Iimpawu kunye neenzuzo ze-API 608 Ball Valve

Iivalvu zebhola eziqinisekisiweyo ze-API 608 zibonelela ngeenzuzo ezibalulekileyo kwimisebenzi yemizi-mveliso:

1. Ukumelana nolwelo oluphantsi: Uyilo olulungiselelweyo lunciphisa ukuhla koxinzelelo, luphucula ukusebenza kakuhle kokuhamba kwamanzi.
2. Ukusebenza ngokukhawuleza: Ukuvula/ukuvala ngokulula ngekota kwenza kube lula ukuvula/ukuvala ngokukhawuleza.
3. Isiqu Esingavumeli Ukuqhushumba: Ithintela ukuphuma kwesiqu phantsi koxinzelelo oluphezulu ukuze kukhuseleke ngakumbi.
4. Izalathisi zeSikhundla: Izalathisi ezibonakalayo okanye ze-mechanical ezicacileyo zokujonga imeko yevalvu.
5. Iindlela zokutshixa: Vimba iivalvu kwiindawo ezivulekileyo/ezivaliweyo ukuthintela ukusebenza ngengozi.
6. Uyilo Olukhuselekileyo Emlilweni: IyahambelanaI-API 607ukumelana nomlilo kwiindawo ezinobungozi.
7. Ulwakhiwo oluchasene nokuqina: Inciphisa ukwakheka kombane ongashukumiyo ukunciphisa iingozi zokuqhuma.

Usetyenziso lwee-API 608 Ball Valves

Ezi valve zilungele:

• Imibhobho yeoyile negesi
• Iinkqubo zokucubungula i-Petrochemical
• Iipayipi zenkqubo ye-ASME B31.3 enoxinzelelo oluphezulu
• Iinkonzo zeenkonzo ezifuna ukuthotyelwa komthetho okhuselekileyo emlilweni okanye ochasene nokumelana ne-static

Isiphelo
Iivalvu zebhola ze-API 608Zenzelwe ukuhlangabezana neemfuno ezingqongqo zoshishino, zidibanisa ukuqina, ukhuseleko, kunye nokusebenza kakuhle. Ukunamathela kwazo kwimigangatho eyaziwayo kwihlabathi liphela efana ne-ASME B16.5 kunye ne-API 607 ​​kuzenza zibe lukhetho oluthembekileyo kwizicelo ezibalulekileyo kumacandelo amandla kunye nemveliso.
