Ezinkambisweni zezimboni, izinga lokushisa eliphezulu kanye nezindawo zokucindezela okuphezulu yizimo ezivamile.Kusukela kuwoyela negesi kuya ezimbonini zamakhemikhali nezepetrochemical, isidingo samavalvu athembekile, asebenza kahle angakwazi ukumelana nezimo ezimbi kakhulu sibalulekile.Yilapho izinga lokushisa eliphezulu kanye nama-valve okucindezela okukhulu aqala khona futhi ayingxenye ebalulekile yokuqinisekisa ukuphepha nokusebenza kahle kwemisebenzi ehlukahlukene yezimboni.
Ama-valve okushisa aphezulu kanye nokucindezela okuphezulu aklanyelwe ngokukhethekile ukubhekana nezimo ezinzima ezitholakala ezimbonini lapho amazinga okushisa aphezulu kanye nokucindezela kuyizici eziqhubekayo.Lawa ma-valve akhiwe ukuze amelane nobunzima balolu hlobo lwendawo, anikeze ukusebenza okuthembekile nokuqinisekisa ubuqotho balo lonke uhlelo.
Esinye sezici ezibalulekile ezihlukanisa ama-valve okushisa aphezulu kanye nokucindezela okuphezulu kusuka kuma-valve ajwayelekile yikhono lawo lokumelana nezimo ezimbi ngaphandle kokuphazamisa ukusebenza kwawo.Lawa ma-valve enziwe ngezinto ezimelana nokushisa okuphezulu nezingcindezi, njengensimbi engagqwali, insimbi ye-alloy kanye namanye ama-alloys akhethekile.Lokhu kuqinisekisa ukuthi i-valve igcina ubuqotho bayo besakhiwo nokusebenza ngisho nalapho ivezwe emazingeni okushisa aphezulu kanye nezingcindezi.
Ngaphezu kokwakhiwa okuqinile, izinga lokushisa eliphezulu kanye nama-valve okucindezela okukhulu aklanyelwe ngezindlela zokuvala ezithuthukisiwe zokuvimbela ukuvuza nokuqinisekisa ukuvala okuqinile.Lokhu kubalulekile embonini lapho noma yiluphi uhlobo lokuvuza lungaba nemiphumela eyinhlekelele.Lawa ma-valve agcina uphawu oluvikelekile ngisho nangaphansi kwezimo ezimbi kakhulu, okubalulekile ekuphepheni nasekuthembekeni kwalo lonke uhlelo.
Ngaphezu kwalokho, ama-valve okushisa aphezulu kanye nokucindezela okuphezulu avame ukuza nezici ezifana namabhonethi anwetshiwe kanye nokupakisha okukhethekile ukuze kunikeze ukuvikeleka okwengeziwe ezimeni zokusebenza ezinzima.Lezi zici zisiza ukunciphisa imiphumela yamazinga okushisa aphezulu nezingcindezi ezingxenyeni zamavalvu, zandise impilo yazo yesevisi futhi zinciphise isidingo sokunakekelwa njalo nokushintshwa.
Ama-valve aphezulu okushisa kanye nokucindezela okuphezulu asetshenziswa ezinhlobonhlobo zezicelo, kusukela kuzinhlelo ze-steam kanye nezitshalo zokubhayela kuya ezinkambisweni zokucwenga kanye nezindawo zokuphehla amandla.Isibonelo, ezinhlelweni ze-steam, izinga lokushisa eliphezulu kanye nama-valve okucindezela okukhulu adlala indima ebalulekile ekulawuleni ukugeleza kwe-steam nokucindezela nokuqinisekisa ukusebenza kahle nokuphephile.Ngokufanayo, phakathi nenqubo yokucwenga, lawa ma-valve asetshenziselwa ukulawula ukugeleza kwamanzi okushisa aphezulu kanye nokucindezela okukhulu, okusiza ukuthuthukisa ukusebenza kahle kokusebenza kokucwenga.
Embonini kawoyela negesi, ama-valve anezinga lokushisa eliphezulu kanye nengcindezi ephezulu abalulekile ekulawuleni ukugeleza kwama-hydrocarbon nolunye uketshezi kuma-wellheads, amapayipi, nasezindaweni zokucubungula.Ikhono lalawa mavalvu ukumelana nezimo ezinzima ezitholakala ekusebenzeni kukawoyela negesi kubalulekile ekuqinisekiseni ukuphepha nokuthembeka kwayo yonke ingqalasizinda.
Ukwengeza, ezitshalweni zamakhemikhali kanye ne-petrochemical, ama-valve okushisa aphezulu kanye ne-high-pressure ayingxenye ebalulekile yokuphatha nokucubungula uketshezi olubolayo kanye nokushisa okuphezulu.Lawa ma-valve aklanyelwe ukumelana nemiphumela elimazayo yamakhemikhali futhi agcine ukusebenza kwawo ngaphansi kwezimo ezinzima ezivame ezindaweni ezinjalo.
Ngamafuphi, izinga lokushisa eliphezulu kanye nama-valve okucindezela okuphezulu kuyizici ezibalulekile ekusebenzeni kwezimboni lapho izimo ezimbi ziyinselele njalo.Ikhono labo lokumelana nezinga lokushisa eliphezulu nezingcindezi, ukugcina ukuvala okuqinile, nokuhlinzeka ngokusebenza okuthembekile kubenza babaluleke kakhulu ekuqinisekiseni ukuphepha nokusebenza kahle kwezinqubo ezihlukahlukene zezimboni.Njengoba imboni iqhubeka nokuphusha imingcele yezimo zokusebenza, isidingo samavalvu okushisa aphezulu kanye nomfutho ophakeme sizoqhubeka sikhula, sigcizelela ukubaluleka kwawo kubunjiniyela bezimboni nokuphepha.
