Amavalvu esango le-Wellhead ayingxenye ebalulekile yezinhlelo zokukhiqiza uwoyela negesi, adlala indima ebalulekile ekulawuleni ukugeleza koketshezi oluphuma emthonjeni.Lawa ma-valve aklanyelwe ukumelana nezimo ezinomfutho ophezulu kanye nezinga lokushisa eliphezulu, okuwenza abaluleke kakhulu ekusebenzeni okuphephile nokusebenza kahle kwama-wellheads.Kulesi sihloko, sizohlola inhloso ye-valve yesango le-wellhead futhi sixoxe ngama-lubricant angcono kakhulu ama-valve wesango ukuqinisekisa ukusebenza kwawo okuhle.
Inhloso ye-Wellhead Gate Valve
Inhloso eyinhloko ai-valve yesango elihleiwukulawula ukugeleza koketshezi olufana nowoyela, igesi, namanzi emthonjeni.Lawa ma-valve afakwa esihlokweni somthombo, lapho esebenza khona njengesithiyo sokulawula ukugeleza kwama-hydrocarbon nezinye izinto ezikhishwa echibini.Ngokuvula noma ukuvala i-valve, opharetha bangavumela ukugeleza kwamanzi noma bavale ngokuphelele, banikeze indlela yokulawula inqubo yokukhiqiza.
Ngaphezu kokulawula ukugeleza, ama-valve amasango e-wellhead nawo adlala indima ebalulekile ekuphepheni kwe-wellhead.Esimeni esiphuthumayo, njengokuqhuma noma ukukhishwa okungalawuleki koketshezi, i-valve yesango ingavalwa ngokushesha ukuze ihlukanise umthombo futhi ivimbele ukwanda kwesimo.Leli khono libalulekile ekuvikeleni abasebenzi, okokusebenza, kanye nendawo ezungezile ezingozini ezingaba khona ezihlobene nokusebenza kwe-wellhead.
I-Lubricant ehamba phambili yamavalvu esango
Ukugcotshwa okufanele kubalulekile ukuze kugcinwe ukusebenza nokuhlala isikhathi eside kwamavalvu esango, kuhlanganise nalawo asetshenziswa ekufakweni kwe-wellhead.Ukukhethwa kwezinto zokugcoba kungaba nomthelela omkhulu ekusebenzeni kwevalvu, ikakhulukazi ezimweni ezinzima zokusebenza ezivame ukuhlangana nazo embonini kawoyela negesi.Lapho ukhetha i-lubricant yama-valve wesango, izici eziningana kufanele zicatshangelwe, okuhlanganisa izinga lokushisa, ingcindezi, nokuhambisana nezinto ze-valve.
Enye yezinto zokugcoba ezinhle kakhuluama-valve esangoiyikhwalithi ephezulu, amafutha okwenziwa aklanyelwe ukusetshenziswa kwamavalvu.Amafutha okwenziwa ahlinzeka ngokusebenza okuphezulu emazingeni okushisa aphezulu futhi anikeza ukumelana okuhle kakhulu ne-oxidation kanye nokuwohloka, okuqinisekisa ukusebenza kahle kokugcotshwa kwesikhathi eside.Lawa mafutha aphinde anikeze isivikelo esithuthukisiwe ekugqwaleni nasekugugeni, okubalulekile kumavalvu esango achayeka ezindaweni zokusebenza ezinokhahlo.
Ngaphandle kwamafutha okwenziwa, amanye ama-valve esango angase azuze ekusetshenzisweni kwezithambisi zefilimu ezomile, ezihlinzeka ngendwangu encane, evikelayo enciphisa ukungqubuzana nokuguga.Izithambisi zefilimu ezomile zifaneleka ikakhulukazi kumavalvu asebenza ngaphansi kwezimo ezishisa kakhulu noma ezinengcindezi ephezulu, lapho amafutha avamile engase angasebenzi kahle.Ngokwenza ungqimba oluhlala isikhathi eside, olunokungqubuzana okuphansi ezingxenyeni zevalvu, okokugcoba kwefilimu okomile kungasiza ukuthuthukisa ukusebenza nokuthembeka kwevalvu.
Kubalulekile ukuqaphela ukuthi ukukhethwa kwe-lubricant engcono kakhulu ye-i-valve yesangokufanele kusekelwe ezincomweni zomkhiqizi kanye nezindlela ezihamba phambili zemboni.Ukusetshenziswa ngendlela efanele kanye nokugcinwa kwe-lubricant ekhethiwe nakho kubalulekile ukuze kuqinisekiswe ukusebenza kahle kwe-valve nokuphila isikhathi eside.Ukuhlolwa njalo kanye nokugcotshwa kabusha kwamavalvu esango kufanele kwenziwe njengengxenye yohlelo oluphelele lokulungisa ukuvimbela izinkinga ezinjengokunamathela kwamavalvu noma ukuguga ngokweqile.
Isiphetho
Ama-valve esango le-Wellhead ayingxenye ebalulekile yezinhlelo zokukhiqiza uwoyela negesi, asebenzela izinhloso ezimbili zokulawula ukugeleza nokuphepha.Ukukhetha okufanele kanye nokusetshenziswa kwezithambisi kubalulekile ekuqinisekiseni ukusebenza kahle nokuhlala isikhathi eside kwamavalvu esango, okuhlanganisa nalawo afakwe emithonjeni yamanzi.Ngokusebenzisa okokugcoba kwekhwalithi ephezulu okuhambisana nezimo zokusebenza nezinto zokwakha zama-valve, opharetha bangasiza ekunciphiseni izidingo zokulungisa futhi bakhulise ukwethembeka kwezinhlelo zabo zamavalvu esango le-wellhead.
