Ukuqonda imisebenzi yama-valve okuminyanisa emishinini yokulawula umthombo
Emishinini yokulawula umthombo,vala ama-valve idlala indima ebalulekile ekulawuleni ukugeleza koketshezi emithonjeni kawoyela negesi. Lawa ma-valve aklanyelwe ukulawula ukucindezela nokugeleza koketshezi, ukuqinisekisa ukuphepha nokusebenza kahle kwemisebenzi yokumba. Kule bhulogi, sizobhekisisa ukuthi kanjanivala ama-valveumsebenzi kanye nokubaluleka kwawo kuimishini yokulawula kahle.
Ama-valve e-Choke ngokuvamile afakwe kuwoisihlahla sikaKhisimusi , ingxenye yomthombo ohlinzeka ngokulawula nokufinyelela kumthombo. Umsebenzi oyinhloko we-valve yokuminyanisa ukukhawulela ukugeleza koketshezi emthonjeni kawoyela, ngaleyo ndlela ulawule ukucindezela nokuvimbela noma yikuphi ukuqhuma okungase kube khona noma ukukhululwa okungalawuleki kwama-hydrocarbon. Lokhu kubaluleke kakhulu ngesikhathi sokumba, ukuqeda kanye nokusebenza kokukhiqiza, lapho umfutho wamanzi kanye namazinga okugeleza kudingeka kulawulwe ngokucophelela ukuze kuqinisekiswe ukuphepha kwabasebenzi kanye nobuqotho bemithombo.
Umgomo wokusebenza we-throttle valve uhilela ukusetshenziswa kwe-orifice eguquguqukayo ukuze ulawule ukugeleza koketshezi. Ngokulungisa ukuvuleka kwe-valve, opharetha bangakwazi ukulawula ukugeleza nokucindezela koketshezi ukuze baphathe ngokunembile izimo ze-wellbore.I-valve yokuvalaingasebenza ngesandla noma ifakwe izilawuli ezizenzakalelayo, kuye ngezidingo ezithile zomthombo kanye nokusebenza kokumba.
Ngaphezu kokulawula ukugeleza koketshezi, ama-valve okuminyanisa nawo adlala indima ebalulekile ekulawuleni kahle i-backpressure. Ngesikhathi sokusebenza okuthile, njengokuhlola umthombo noma ukukhiqizwa, ukucindezela okuqondile okuthile kufanele kugcinwe ukuze kuthuthukiswe ukugeleza koketshezi futhi kuqinisekiswe ubuqotho bechibi. Ama-valve e-Throttle asiza ukufeza nokugcina ingcindezi yangemuva edingekayo yokukhiqiza okuphumelelayo nokuphathwa kwe-reservoir.
Ngaphezu kwalokho, ama-valve okuminyanisa aklanyelwe ukumelana nezimo ezinzima okuhlangatshezwana nazo ngesikhathi sokulawula umthombo. Zenziwe ngezinto ezisezingeni eliphezulu futhi zifakwe izigxivizo nokupakisha ukuze kuqinisekiswe ukusebenza okuthembekile ezindaweni ezinomfutho ophezulu kanye nokushisa okuphezulu. Lokhu kwakhiwa okumazombezombe kubalulekile ekuqinisekiseni ukuphepha nobuqotho bemishini yokulawula umthombo, ikakhulukazi ngesikhathi sokusebenza okubucayi njengokulawula umthombo kanye nokuvimbela ukuqhunyiswa.
Kafushane, ama-valve okuminyanisa ayingxenye ebalulekile yezinto zokusebenza zokulawula umthombo futhi adlala indima ebalulekile ekulawuleni ukugeleza koketshezi nokulawula umfutho kawoyela negesi emthonjeni. Ikhono labo lokulawula ukugeleza, i-backpressure kanye ne-fluid dynamics kubalulekile ekuqinisekiseni ukuphepha nokusebenza kahle kokumba, ukuqeda kanye nokusebenza kokukhiqiza. Ukuqonda ukusebenza nokubaluleka kwamavalvu okuminyanisa kubalulekile kunoma yimuphi umdlali embonini kawoyela negesi njengoba ebalulekile ekugcineni ubuqotho bomthombo nokuqinisekisa impumelelo yokusebenza kokumba.
