Qonda imisebenzi eyisisekelo yamavalvu esango emishinini yokulawula kahle

Phakathi kwemishini yokulawula umthombo,ama-valve esangoidlala indima ebalulekile ekuqinisekiseni ukusebenza ngokuphephile nangempumelelo kwemithombo kawoyela negesi. Lawa ma-valve aklanyelwe ukulawula ukugeleza koketshezi ngaphakathi komthombo, okuwenza abe yingxenye ebalulekile yawo wonkeuhlelo lokulawula kahle. Kule bhulogi, sizobhekisisa imisebenzi yamavalvu esango nokubaluleka kwawo ekugcineni ubuqotho nokuphepha.

Okokuqala nokubaluleke kakhulu, ama-valve esango anesibopho sokulawula ukugeleza koketshezi ngaphakathi komthombo. Kungakhathaliseki ukuthi ngesikhathi sokumba, ukukhiqiza noma ukusebenza kokungenelela, lawa ma-valve asetshenziselwa ukuvula noma ukuvala imigudu okudlula uketshezi. Lesi sici sibalulekile ekulawuleni ingcindezi nokugeleza koketshezi, ukuvimbela noma yikuphi ukuqhunyiswa okungaba khona noma ukukhishwa okungalawuleki kwama-hydrocarbon.

Ngaphezu kokulawulwa kokugeleza,ama-valve esangoingasetshenziswa futhi njengemishini yokuhlukanisa engahlukanisa izingxenye ezithile zomthombo. Leli khono libalulekile ngesikhathi sokulawulwa komthombo njengoba lenza opharetha akwazi ukulawula noma yikuphi ukungena okungalindelekile koketshezi noma igesi, ngaleyo ndlela kuvinjwe noma iyiphi ingozi engaba khona noma umonakalo wendawo.

Ukwengeza, ama-valve esango aklanyelwe ukunikeza uphawu oluqinile lapho evaliwe, ukuvimbela ngokuphumelelayo ukuvuza kwamanzi noma igesi. Lesi sici sibalulekile ekugcineni ubuqotho bomthombo kanye nokuqinisekisa ukuthi indawo ezungezile ayiphazanyiswa.I-valve yesangoIkhono lokudala uphawu oluthembekile libalulekile ekuvimbeleni noma yiziphi izigameko ezingase zibe khona zokulawula umthombo kanye nokuphepha okuphelele komsebenzi wokulungisa.

Ngaphezu kwalokho, ama-valve esango avame ukuhlonywa ngezinto ezimangelengele eziwavumela ukuba amelane nokucindezela okuphezulu nezimo zokushisa ezivamile emisebenzini yokulawula umthombo. Lokhu kuqinisekisa ukuthi i-valve ingakwazi ukubhekana ngokuphumelelayo nezimo ezinzima ngaphakathi komthombo, okufaka isandla ekuthembekeni okuphelele nokuphepha kwemishini.

Emishinini yokulawula kahle, ama-valve esango avame ukuhlanganiswa esitakini sokuvimbela i-blowout (BOP), okuyingxenye ebalulekile ohlelweni lokulawula umthombo. Izitaki zokuvimbela i-Blowout zifakwe amavalvu esango amaningi futhi ziwumugqa wokugcina wokuzivikela ezimeni eziphuthumayo zokulawula umthombo njengokukhahlela noma ukuqhunyiswa. Ukusebenza okuthembekile kwamavalvu esango ngaphakathi kwesitaki sokuvimbela ukuvuthela kubalulekile ekudambiseni noma yiziphi izigameko ezingaba khona zokulawula umthombo kanye nokuvikela umthombo nendawo ezungezile.

Kafushane, ama-valve esango adlala indima ebalulekile emishinini yokulawula kahle enemisebenzi eyisisekelo njengokulawula ukugeleza, ukuhlukaniswa, ukuvala uphawu, nokumelana nezimo zokusebenza ezinzima. Ukuhlanganiswa kwazo kuzitaki ze-BOP kugcizelela ukubaluleka kwazo ekugcineni ubuqotho nokuphepha. Ukuqonda umsebenzi nokubaluleka kwama-valve esango emishinini yokulawula kahle kubalulekile ukuze kuqinisekiswe ukusebenza kahle nokuphephile kukawoyela negesi kahle.
