Njengombana itjhada lingaba nomthelela omumbi emzimbeni womuntu, amafrikhwensi athileko angadlala umonakalo emitjhini yamabubulo lokha i-valve yokulawula nayikhethwe kuhle, kunengozi ekhuphukileko yokuvuvuka, okuzokurholela ekutheni kube nomsindo omkhulu namazinga wokuthuthumela, okuzokwenza bona kube nokulimala okurhaba khulu emapayipini wangaphakathi nangaphasi we-ivalvu.
Ukungezelela, amazinga aphezulu womsindo avamise ukubangela ukudlidliza okungalimaza amapayipi, iinsetjenziswa nezinye iinsetjenziswaIvalvungokukhamba kwesikhathi, ukuwohloka kweengcenye, ukuvuvuka kwevalvu okubangelwa lihlelo lamapayipi elithambekele ekulimaleni okukhulu. Umonakalo lo ubangelwa khulu mamandla womsindo wokudlidliza, ikambiso yokugqwala okurhabako kanye nokuvuvuka okuvezwa lizinga eliphezulu lomsindo wokudlidliza okukhulu okwenziwa kukwakheka nokuwohloka kwamabhamuza womtjhiso eduze nangezansi kokuncipha.
Nanyana lokhu kuvamise ukwenzeka ebholweniamavalvukanye namavalvu ajikelezako emzimbeni, kungenzeka kwamambala ngokubuyiselwa okufitjhani, okuphezulu okufana nengcenye yomzimba we-wafer ye-V-ballivalvu, khulukhuluamavalvu wevithaminingehlangothini eliphasi levalvu lokhaivalvuigandelelekile endaweni eyodwa ethambekele ekubeni yi-cavitation phenomenon, ethambekele ekuvuzeni emaphayiphini wevalvu nokulungiswa kokuwelda, ivalvu ayifaneleki lesi sigaba somzila.
Kungakhathaliseki bona ukuvuvuka kwenzeka ngaphakathi kwevalvu nofana ezansi kwevalvu, iinsetjenziswa ezisendaweni yokuvuvuka zizokulimala khulu kumafilimu amancani khulu, ama-spring kanye nezakhiwo ezincani ze-cantilever, ukudlidliza okukhulu kungabangela ukunyakaza. Amaphuzu wokuhluleka kanengi atholakala eensetjenzisweni ezifana nama-pressure gauge, ama-transmitter, ama-thermocouple sleeves, ama-flowmeters, ama-sampling systems Ama-actuators, ama-positioners kanye nama-limit switches anama-springs azokuguga msinyana, begodu ama-mounting brackets, ama-fasteners kanye nama-connectors azokukhululeka begodu ahluleke ngebanga lokudlidliza.
Ukugqwala kwe-fretting, okwenzeka hlangana neendawo ezigugileko ezivezwe kukudlidliza, kuvamile eduze kwamavalvu we-cavitation. Lokhu kukhiqiza ama-oxide aqinileko njengeenhlahla ukurhabisa ukuguga hlangana neendawo ezigugileko. Iinsetjenziswa ezithintekako zifaka hlangana amavalvu wokuhlukanisa nokuhlola, ngaphezu kwamavalvu wokulawula, amapompo, amaskrini ajikelezako, amasampula nanyana ngiyiphi enye indlela ejikelezako nofana etjhelelako.
Ukudlidliza okukhulu nakho kungaqhekeka begodu kugcolise amalunga wevalvu yensimbi namaboda wamapayipi. Iinhlayiya zensimbi ezihlakazekileko nofana izinto zamakhemikhali ezibolako zingasilaphaza iindaba ezisephayiphini, okungaba nomthelela omkhulu emaphayiphini wevalvu ahlanzekileko kanye nemidiya yamapayipi ahlanzekileko. Lokhu akukavunyelwa.
Ukubikezela ukubhalelwa kwe-cavitation kwamavalvu wepulagi kuyinkimbinkimbi begodu akusikho ukwehla komfutho wokugandeleleka okubalwa kwaphela. Isipiliyoni sitjengisa bona kungenzeka bona umfutho emfudlaneni omkhulu wehlela emfuthweni womhwamuko we-liquid ngaphambi kokuhwamuka kwendawo kanye nokuwohloka kwebhamuza lomtjhiso. Abanye abakhiqizi bamavalvu babikezela ukwehluleka kokufiphala kwelanga ngaphambi kwesikhathi ngokuhlathulula ukwehla komfutho womonakalo wokuthoma. Indlela yomkhiqizi wamavalvu yokuthoma ngokubikezela umonakalo wokuvuvuka isekelwe eqinisweni lokuthi amabhamuza womtjhiso ayabhidlika, abangela ukuvuvuka nomsindo. Kutholwe bona umonakalo omkhulu we-cavitation uzokubalekelwa nangabe izinga lomsindo elibalwe lingaphasi kwemikhawulo ebhalwe ngenzasi.
Ubukhulu bevalvu ukuya ku-3 intshi - 80 dB
Ubukhulu bevalvu obuyi-4-6 intshi - 85 dB
Ubukhulu bevalvu 8-14 intshi - 90 dB
Ubukhulu bevalvu obuyi-16 intjhi ukuya phezulu – 95 dB
Iindlela zokuqeda umonakalo we-cavitation
Idizayini ekhethekileko yevalvu yokuqeda ukuvuvuka isebenzisa ukugeleza okuhlukanisiweko kanye nokwehla komfutho okulinganisiweko:
“Ukuphambukiswa kwevalvu” kuhlukanisa ukugeleza okukhulu kube ziingeleza ezincani ezinengi, begodu indlela yokugeleza kwevalvu yenzelwe ukwenzela bona ukugeleza kugeleze ngeenkhathi ezinengi ezincani ezifanako. Njengombana ingcenye yobukhulu be-cavitation bubble ibalwa ngokuvuleka lapho ukugeleza kudlula khona. Ukuvuleka okuncani kwenza bona kube namabhamuza amancani, okwenza bona kube nomsindo omncani begodu kube nomonakalo omncani lokha nakuziwa ekulimaleni.
"Ukwehla komfutho okulinganiselweko" kutjho bona ivalvu yenzelwe bona ibe namaphuzu amabili nofana ngaphezulu wokulungisa ngokulandelana, njeke esikhundleni sokwehla koke komfutho ngesinyathelo sinye, kuthatha amagadango amanengi amancani. Ngaphasi kokwehla kwengcindezi ngamunye kungavimbela umfutho ekunciphiseni ukusuka ekwehleni komfutho womhwamuko we-liquid, ngaleyo ndlela kuqedwe isenzakalo sokuvuvuka ku-valve.
Ukuhlanganiswa kokuphambukisa nokwehla komfutho ku-valve efanako kuvumela ukujamelana nokuvuvuka okuthuthukisiweko. Ngesikhathi sokutjhugululwa kwevalvu, ukubeka ivalvu yokulawula begodu umfutho ekungeneni kwevalvu uphezulu (isib., ngehlangothini elide phezulu, nofana ekuphakameni okuphasi), kesinye isikhathi kuqeda imiraro yokuvuvuka.
Ukungezelela, ukubeka ivalvu yokulawula endaweni yamazinga womtjhiso we-liquid, begodu ngalokho-ke umfutho ophasi womhwamuko (njenge-exchanger yokutjhisa ehlangothini lokutjhisa eliphasi) kungasiza ukuqeda imiraro yokutjhisa.
Isifinyezo sitjengise bona isenzakalo sokuvuvuka kwamavalvu akusikho kwaphela ngokusebenza kokuwohloka nokulimala kwamavalvu. Amapayipi aphasi nemitjhini nayo isengozini. Ukubikezela ukuvuvuka nokuthatha amagadango wokukuqeda yindlela yodwa yokubalekela umraro weendleko ezibizako zokusebenzisa amavalvu.
