Uma kuziwa kuma-valve ezimbonini, ama-valve ebhola alayisha phezulu ayingxenye ebalulekile ezinhlelweni eziningi. Lolu hlobo lwe-valve lwaziwa ngokwethembeka, ukuqina, kanye nokuguquguquka, okulwenza lube ukukhetha okudumile kuzo zonke izimboni ezihlukahlukene. Kulo mhlahlandlela obanzi, sizobheka ngokujulile izici ezibalulekile, izinzuzo, kanye nokusetshenziswa kwamavalvu ebhola okufinyelela phezulu.
Izici eziyinhloko zama-valve ebhola afakwe phezulu
Amavalvu ebhola okufinyelela phezulu aklanywe anendawo yokungena ebekwe phezulu ukuze kufinyeleleke kalula ezingxenyeni zangaphakathi. Lesi sici sivumela ukugcinwa okusheshayo nokulula, ukulungiswa nokushintshwa kwezingxenye ngaphandle kokukhipha i-valve epayipini. Ukwengeza, idizayini yokungena phezulu inciphisa ubungozi bokuvuza futhi iqinisekise ukuvaleka okuqinile, okuyenza ifaneleke kakhulu ekusetshenzisweni komfutho ophezulu kanye nezinga lokushisa eliphezulu.
Esinye isici esihlukanisayo se-valve yebhola yokufinyelela ephezulu ukwakheka kwayo kwembobo egcwele, evumela ukugeleza okungavinjelwe kanye nokwehla kwengcindezi encane. Lesi sici somklamo sibalulekile ezinhlelweni zokusebenza ezidinga ukugeleza koketshezi okusebenzayo nokulahlekelwa amandla okuncane.
Izinzuzo zama-valve ebhola afakwe phezulu
Enye yezinzuzo eziyinhloko zamavalvu ebhola okufinyelela phezulu ukwakhiwa kwawo okumazombezombe, ngokuvamile okwenziwa ngezinto zekhwalithi ephezulu njengensimbi engagqwali, i-carbon steel, noma i-alloy steel. Lokhu kwakhiwa kuqinisekisa isikhathi eside se-valve futhi kunciphisa isidingo sokugcinwa njalo nokushintshwa, ngisho nangaphansi kwezimo zokusebenza ezinzima.
Ngaphezu kwalokho, ama-valve ebhola abekwe phezulu asebenza kahle kakhulu ngenxa yomklamo wawo webhola elintantayo kanye nezinto ezithembekile zokuvala. Lesi sici senza i-valve ifanelekele ukusetshenziswa noketshezi oluhlukahlukene, okuhlanganisa imidiya ebolayo ne-abrasive, ngaphandle kokuphazamisa ukusebenza kwayo.
Izicelo zama-valve ebhola afakwe phezulu
Ama-valve amabhola alayisha phezulu asetshenziswa ezimbonini ezihlukahlukene, okuhlanganisa uwoyela negesi, amakhemikhali e-petrochemicals, ukucubungula amakhemikhali, ukuphehla ugesi nokuhlanza amanzi. Ukuguquguquka kwayo kanye nekhono lokusingatha izingcindezi eziphezulu namazinga okushisa kuyenza ifanelekele izinhlelo zokusebenza ezibucayi ezifana nokuvala, ukuhlukaniswa nokulawula ukugeleza koketshezi.
Embonini kawoyela negesi, ama-valve ebhola afakwe phezulu avame ukusetshenziswa ezinhlelweni zamapayipi, ama-wellheads kanye nezindawo zokukhiqiza. Ikhono labo lokumelana nezimo zokusebenza ezinzima futhi linikeze ukuvala shaqa okuthembekile kubenza babe yingxenye ebalulekile ekuqinisekiseni ukuphepha nokusebenza kahle kokusebenza kukawoyela negesi.
Ezimbonini zokucubungula amakhemikhali kanye nezamakhemikhali e-petrochemical, amavalvu ebhola abekwe phezulu asetshenziselwa ukuphatha uketshezi olubolayo noluhubhukayo ngenxa yokwakhiwa kwawo okumazombezombe kanye nezindawo ezinhle kakhulu zokuvala. Lawa ma-valve adlala indima ebalulekile ekulawuleni ukugeleza kwamakhemikhali nokuqinisekisa ubuqotho bezinhlelo zenqubo.
Sengiphetha, i-valve yebhola yokufinyelela ephezulu iyingxenye eguquguqukayo nethembekile enikeza izinzuzo eziningi zezinhlobonhlobo zezicelo zezimboni. Idizayini yayo yokungena ephezulu, ukwakhiwa okumazombezombe kanye nezakhiwo ezinhle kakhulu zokuvala kuyenza ibe ukukhetha kokuqala kwezinhlelo zokusebenza zokulawula uketshezi olubalulekile. Kungakhathaliseki ukuthi ku-oyela negesi, ukucutshungulwa kwamakhemikhali noma izimboni zokukhiqiza amandla, ama-valve ebhola afakwe phezulu ahlala edlala indima ebalulekile ekuqinisekiseni ukuphepha, ukusebenza kahle nokuthembeka kwezinqubo zezimboni.
