Emkhakheni wamavalvu ezimbonini, ama-valve evemvane kathathu agqama njengezixazululo eziguquguqukayo nezisebenzayo zokusetshenziswa okuhlukahlukene.Ngomklamo wawo oyingqayizivele nokusebenza okuthuthukisiwe, lawa ma-valve anikeza izinzuzo eziningi kuwoyela negesi, ukucubungula amakhemikhali, ukukhiqiza amandla nezinye izimboni.Kule bhulogi, sizohlola izici eziyinhloko kanye nezinzuzo zama-valve ovemvane we-offset kathathu, kanye nokusebenza kwawo nokubaluleka ezinqubweni ezihlukahlukene zezimboni.

Ama-valve evemvane okuphuma kathathu aklanyelwe ukuhlinzeka ngokulawula ukugeleza kwamapayipi okuthembekile nokunembayo, okuwenza abe yingxenye ebalulekile ezinhlelweni eziningi zezimboni.Ngokungafani namavalvu ovemvane endabuko asebenzisa idizayini ye-concentric disc elula, amavalvu evemvane eccentric kathathu asebenzisa ukuhlelwa kwesihlalo esine-tapered ukuze aqede ukungqubuzana nokuguga, ngaleyo ndlela athuthukise ukusebenza kokuvala nokwelula impilo yesevisi.Lo mklamo osha futhi uvumela ukuvala okuqinile kanye nokuvala uphawu kabili, okwenza ivalve uvemvane we-offset kathathu ifanele ukulawula nokusetshenziswa kwayo yodwa.

Enye yezinzuzo eziyinhloko zama-valve ama-butterfly ama-triple offset yikhono lawo lokusingatha ukucindezela okuphezulu nezimo zokushisa eziphakeme kalula.Lawa ma-valve afaka ukwakhiwa okumazombezombe kanye nezinto eziklanyelwe izindawo ezinokhahlo lapho ukuphepha nokuthembeka kubaluleke kakhulu.Ukwengeza, i-torque ephansi ye-valve ye-butterfly ephindwe kathathu kanye nokusebenza ngokushesha kuyenza ilungele izinhlelo ezidinga ukwenziwa kwe-valve kaningi noma ngokushesha.

Ngokuphathelene nokuhlukahluka, ama-valve evemvane eccentric kathathu angasetshenziswa emithonjeni ehlukahlukene, kuhlanganise namanzi, umusi, umoya, igesi namakhemikhali ahlukahlukene.Lokhu kuvumelana nezimo kubenza babe ukukhetha okuthandwayo ezimbonini ezidinga izixazululo zamavalvu ezikwazi ukuphatha izinhlobo ezahlukene zoketshezi.Ukwengeza, idizayini ehlangene futhi engasindi yevalve yevemvane kathathu yenza kube lula ukuyifaka nokuyinakekela, kunciphisa izindleko zokusebenza zizonke kanye nesikhathi sokuphumula.

Ubuchwepheshe bokuvala uphawu obuthuthukile bevalve yevemvane kathathu busiza futhi ukuthuthukisa ukusebenza kahle nokusebenza kwawo.Idizayini ye-offset yediski iqinisekisa ukuvala okuqinile okunokungqubuzana okuncane, okuholela ekugugeni okuncane nokuvuza.Lokhu akuthuthukisi nje kuphela ukusebenza kahle kohlelo lonke kodwa futhi kunciphisa ubungozi bokungcoliswa kwemvelo kanye nokulahleka komkhiqizo.

Embonini kawoyela negesi, ama-valve evemvane e-eccentric kathathu adlala indima ebalulekile ekulawuleni ukuhamba kukawoyela ongahluziwe, igesi yemvelo kanye nemikhiqizo kaphethiloli ocolisisiwe.Ikhono labo lokumelana nezingcindezi eziphezulu namazinga okushisa, kanye nokumelana nokubola, kubenza babe yingxenye ebalulekile yamapayipi, izindawo zokucwenga kanye nezitshalo ze-petrochemical.Ngokufanayo, embonini yokucubungula amakhemikhali, ama-valve evemvane kathathu asetshenziselwa ukulawula ukugeleza kwezinhlobonhlobo zoketshezi olubolayo noluqhumayo, anikeze ukusebenza okuthembekile nokuhlala isikhathi eside ngaphansi kwezimo zokusebenza eziyinselele.

Olunye uhlelo olubalulekile lwamavalvu evemvane oluphindwe kathathu lusezindaweni zokuphehla ugesi, lapho asetshenziselwa khona ukulawula ukugeleza koketshezi namagesi ezinhlelweni zesitimu namanzi.Amandla okushisa aphezulu kanye nokuvalwa okuqinile kwalawa mavalvu kuwenza alungele ukusetshenziswa okubucayi ezitshalweni zikagesi, okuqinisekisa ukusebenza okuphephile nokusebenza kahle.

Kafushane, ama-valve evemvane kathathu ahlinzeka ngenhlanganisela ephelele yokuguquguquka, ukusebenza kahle nokuthembeka, okuwenza abe ingxenye ebalulekile ezinqubweni ezihlukahlukene zezimboni.Idizayini yayo ethuthukisiwe, ukwakhiwa okumazombezombe kanye nokusebenza kokuvala okuphakeme kukwenza kube ukukhetha kokuqala kwezinhlelo zokusebenza ezidinga ukulawulwa okunembile, ukucubungula okuphezulu nokumelana nezimo zokusebenza ezinzima.Njengoba imboni iqhubeka nokuthuthuka futhi idinga izixazululo ezithuthuke kakhulu zama-valve, ama-valve evemvane e-offset azoqhubeka edlala indima ebalulekile ekulawuleni ukugeleza kwezimboni.
