Uma kukhulunywa ngamavalvu ezimboni, amavalvu ebhola alayisha phezulu ayingxenye ebalulekile ezinhlelweni eziningi. Lolu hlobo lwevalvu lwaziwa ngokuthembeka kwalo, ukuqina kwalo, kanye nokuguquguquka kwalo, okwenza kube ukukhetha okuthandwayo kuzo zonke izimboni. Kulo mhlahlandlela ophelele, sizobheka ngokujulile izici ezibalulekile, izinzuzo, kanye nokusetshenziswa kwamavalvu ebhola afinyelela phezulu.
Izici eziyinhloko zama-valve ebhola afakwe phezulu
Amavalvu ebhola okufinyelela phezulu aklanywe ngendawo yokungena efakwe phezulu ukuze kube lula ukufinyelela izingxenye zangaphakathi. Lesi sici sivumela ukulungiswa, ukulungiswa kanye nokufakwa kwezingxenye ngokushesha nangokulula ngaphandle kokususa ivalvu epayipini. Ngaphezu kwalokho, ukwakheka kokungena okuphezulu kunciphisa ingozi yokuvuza futhi kuqinisekisa ukuvalwa okuqinile, okwenza kube kuhle kakhulu ekusetshenzisweni kokucindezela okuphezulu kanye nokushisa okuphezulu.
Esinye isici esiphawulekayo se-valve yebhola yokufinyelela ephezulu ukwakheka kwayo kwe-full-port, okuvumela ukugeleza okungenamkhawulo kanye nokwehla okuncane kwengcindezi. Lesi sici sokuklama sibalulekile ezinhlelweni zokusebenza ezidinga ukugeleza koketshezi okusebenzayo kanye nokulahlekelwa kwamandla okuncane.
Izinzuzo zamavalvu ebhola afakwe phezulu
Enye yezinzuzo eziyinhloko zamavalvu ebhola afinyelela phezulu ukwakhiwa kwawo okuqinile, ngokuvamile okwenziwe ngezinto ezisezingeni eliphezulu njengensimbi engagqwali, insimbi yekhabhoni, noma insimbi ye-alloy. Lokhu kwakhiwa kuqinisekisa ukuhlala isikhathi eside kwevalvu futhi kunciphisa isidingo sokulungiswa nokufakwa kabusha njalo, ngisho nangaphansi kwezimo zokusebenza ezinzima.
Ngaphezu kwalokho, amavalvu ebhola afakwe phezulu asebenza kahle kakhulu ekuvaleni ngenxa yokwakheka kwawo kwebhola elintantayo kanye nezinto zokuvala ezithembekile. Lesi sici senza ivalvu ifanele ukusetshenziswa nezinhlobo ezahlukene zoketshezi, okuhlanganisa izinto ezibolayo nezigubhayo, ngaphandle kokuphazamisa ukusebenza kwayo.
Ukusetshenziswa kwama-valve ebhola afakwe phezulu
Amavalvu ebhola afakwa phezulu asetshenziswa ezimbonini ezahlukahlukene, okuhlanganisa uwoyela negesi, amakhemikhali kaphethroli, ukucubungula amakhemikhali, ukukhiqizwa kukagesi kanye nokwelashwa kwamanzi. Ukuguquguquka kwawo kanye nekhono lokusingatha ukucindezeleka okuphezulu kanye namazinga okushisa kwenza kube kuhle ukusetshenziswa okubalulekile njengokuvala, ukuhlukaniswa kanye nokulawula ukugeleza koketshezi.
Embonini kawoyela negesi, amavalvu ebhola afakwe phezulu avame ukusetshenziswa ezinhlelweni zamapayipi, eziqongweni zemithombo kanye nasezindaweni zokukhiqiza. Amandla awo okubekezelela izimo zokusebenza ezinzima futhi ahlinzeke ngokuvalwa okuthembekile awenza abe yingxenye ebalulekile ekuqinisekiseni ukuphepha nokusebenza kahle kokusebenza kukawoyela negesi.
Ezimbonini zokucubungula amakhemikhali kanye ne-petrochemical, ama-valve ebhola afakwe phezulu asetshenziselwa ukuphatha uketshezi oluqothulayo nolunamandla ngenxa yokwakhiwa kwawo okuqinile kanye nezakhiwo ezinhle kakhulu zokuvala. Lawa ma-valve adlala indima ebalulekile ekulawuleni ukuhamba kwamakhemikhali nokuqinisekisa ubuqotho bezinhlelo zenqubo.
Ekuphetheni, ivalvu yebhola yokufinyelela ephezulu iyinto eguquguqukayo nethembekile enikeza izinzuzo eziningi zezinhlelo zokusebenza ezahlukahlukene zezimboni. Umklamo wayo wokungena ophezulu, ukwakhiwa okuqinile kanye nezakhiwo ezinhle zokuvala kwenza kube ukukhetha kokuqala kwezinhlelo zokusebenza ezibalulekile zokulawula uketshezi. Kungakhathaliseki ukuthi kusezimbonini zikawoyela negesi, ukucubungula amakhemikhali noma ukukhiqiza ugesi, amavalvu ebhola afakwe phezulu abelokhu edlala indima ebalulekile ekuqinisekiseni ukuphepha, ukusebenza kahle kanye nokuthembeka kwezinqubo zezimboni.
