Umahluko phakathi kwe-API 607 ​​kunye ne-6FA: Uvavanyo loMlilo lweeValve

I-API 607 ​​kunye ne-API 6FAluvavanyo lomlilo kwiivalvu ze-6D kunye ne-6A. Ngokubanzi, iivalvu ze-6D ezinokujikeleza kuphela nge-90° kufuneka zenze i-API 607, ngelixa ezinye kufuneka zenze i-API 6FA. I-API sisifinyezo se-American Petroleum Institute, kwaye i-6FA luvavanyo lomlilo kwiivalvu ze-6A ezisemgangathweni.

Uvavanyo lweevalvu zomlilo lusetyenziselwa ukuqinisekisa ukuba iivalvu zisebenza njani na xa zitsha, zitywinwe kwaye zisebenza njani ngexesha lomlilo nasemva komlilo. Ezi valve zihlala zisetyenziswa kwiimeko ezithile apho kukho iingozi zomlilo. Ngexesha loyilo, kufuneka kuthathelwe ingqalelo ukuba zisenamandla athile okuthwala uxinzelelo, zitywinwe kwaye zisebenza xa zitsha ixesha elithile.

Imigangatho yoVavanyo loMlilo kwiiValve:

1. I-API 607-2016Uvavanyo loMlilo lweeValve kunye neeValve zeKota eziJikelezisiweyo zixhotyiswe ngezihlalo ezingezizo zesinyithi

Ububanzi besicelo:Iivalvu ezine-1/4 turn kunye neevalvu ezinezihlalo ezingezizo ezesinyithi. Ezifana nezi:ivalvu yebhola, ivalvu yebhabhathane, ivalvu yeplagi

2. I-API 6FA-2018: Inkcazo yoVavanyo loMlilo lweeValve

Ububanzi besicelo:Iivalvu ze-API 6A kunye ne-API 6D. Ezifana nezi:ivalvu yebhola, ivalvu yesango, ivalvu yeplagi.

3. I-API 6FD-2008: Iinkcukacha zoVavanyo loMlilo lweeValve zokujonga

Ububanzi besicelo:Ivalvu yokujonga

Iindawo zokuqinisekisa ukhuseleko lomlilo ze-API 6FA

Uvavanyo lokusebenza kukusebenzisa ivalvu phantsi koxinzelelo lovavanyo oluphezulu oluchazwe kumgangatho. Ivalvu isuka ekuvalweni ngokupheleleyo ukuya ekuvulekeni phakathi okanye evulekileyo ngokupheleleyo, kwaye umphunga okwipayipi uyacinywa ukuze uzalise umbhobho ngamanzi. Emva koko umbhobho osezantsi uvaliwe kwaye ukuvuza kwangaphandle kwevalvu kulinganiswa phantsi koxinzelelo lovavanyo oluphezulu oluchazwe kumgangatho. Uvavanyo loxinzelelo oluphantsi emva kokupholisa kukuvuza kwangaphakathi nangaphandle kwevalvu okulinganiswe kuxinzelelo lovavanyo oluphantsi oluchazwe kumgangatho emva kokuba ivalvu inyanzelekile ukuba iphole emva komlilo. Ukuvuza kwangaphandle ngexesha lomlilo kubhekisa ekuvuza ngoqhagamshelo lweflange yomzimba wevalvu, uqhagamshelo olunemisonto kunye nesitywina se-valve stem ngexesha lomlilo phantsi koxinzelelo lovavanyo oluchaziweyo. Ukuvuza kwangaphakathi ngexesha lomlilo kubhekisa ekuvuza ngesihlalo sevalvu ngexesha lomlilo kuxinzelelo lovavanyo oluchaziweyo.

Uvavanyo lomlilo lwevalvu ye-API 607/6FA

Ukugutyungelwa kwe-API607 kunye ne-API6FA kwahlukile. Ukugutyungelwa kwahlulwe ngokubanzi ngokwesayizi, ukugutyungelwa kwenqanaba loxinzelelo, ukugutyungelwa kwezinto kunye nezinye izinto.

Kukho umahluko omkhulu ekukhetheni uxinzelelo lovavanyo. Phakathi kwazo, uxinzelelo oluphantsi lovavanyo oluchazwe kwi-API607 yi-0.2MPa, kwaye uxinzelelo oluphezulu lovavanyo yi-75% yoxinzelelo oluphezulu oluvumelekileyo kwiidigri ezingama-20, ngelixa uxinzelelo oluphantsi lovavanyo kunye noxinzelelo oluphezulu lovavanyo oluchazwe kwi-API6FA zinxulumene nomgangatho wevalvu pound.

I-API 607imisela ukuba iivalvu zovavanyo lwe-ferrite zinokugubungela iivalvu ezenziwe ngezinto zentsimbi ye-austenite kunye ne-duplex, kodwa iivalvu ezinobukhulu obuphakathi kuluhlu lokugubungela nazo kufuneka ziphumelele uvavanyo.

Indlela yovavanyo lwe-ISO15540 yokumelana nomlilo kweendibano zepayipi zeenqanawa

Indlela yovavanyo lwe-ISO15541 yokumelana nomlilo kweendibano zepayipi zeenqanawa

Uvavanyo lobubanzi kunye nexabiso loxinzelelo lovavanyo lokhuseleko lomlilo lwevalvu:

Kuvavanyo lokumelana nomlilo wevalvu, ububanzi kunye nexabiso loxinzelelo zezona zincinci zigubungela ubungakanani obukhulu, umzekelo:

Ngokubanzi, ububanzi bugubungela iinkcukacha eziphindwe kabini ngobukhulu, i-6NPS inokugubungela i-6-12NPS, i-100DN inokugubungela i-100-200DN;

Uvavanyo lovavanyo loxinzelelo, uluhlu lokugubungela nalo luchaziwe, i-25PN inokugubungela i-25-40PN
