Mbuli muzuzumo mboukonzya kuba aampindu zitali kabotu kumubili wamuntu, amwi ma frequency alakonzya kunyonganya zibelesyo zyamafakitali kuti vvalavu yakulela yasalwa kabotu, kuli ntenda mpati ya cavitation, eeyo iikonzya kuleta muzuzumo mupati akuzungaana, eezi ziyoopa kuti mapaipi aamukati amumaanzi anyonyooke chakufwambaanavvalavu.
Mukuyungizya, muzuzumo mupati kanjikanji uletela kuzungaana ooko kukonzya kunyonyoona mapaipi, zibelesyo azibelesyo zimwiValvemukuya kwachiindi, kunyonyooka kwazibeela, kuvwundauka kwavalvu kwakachitwa anzila yamapayipi aakonzya kunyonyooka loko. Ooku kunyonyooka kuchitwa anguzu zyakuzungaana, kufwambana kwakubola akuvwundauka kwakatondezyegwa akuzungaana kupati kwakuzungaana kupati kwakachitika akaambo kakupangwa akuwida kwamabbubbu aamuwo afwaafwi akuselemuka kwakucheya.
Nikuba kuti eezi zilachitika mubbolamavalvuantoomwe amavalvu aazunguluka mumubili, zilakonzya kuchitika muchiindi chifwiifwi, chilamfu loko mbuli chibeela chamubili wa wafer wa V-ballvvalavu, ikapatimavwili aabutterflykulubazu lwamunsi lwa valve aawovvalavuilikatazyidwe muchiimo chimwi chikonzya kuchitika akaambo kakuvwundauka, ooko kukonzya kuvwundauka mumapaipi aavalvu akubambulula, ivalvu tayeelede pe kuchibeela eechi chamuzila.
Nikuba kuti kuvwundauka kwachitika mukati ka vvalavu naa munsi lya vvalavu, zibelesyo zili mubusena bwakuvwundauka zilakonzya kunyonyooka kapati amafilimu mateteete, ma spring alimwi azibeela zisyoonto zya cantilever, kuzungaana kupati kulakonzya kupa kuti kube kuzungaana. Ziindi zyiingi zitabeleki kabotu zilajanwa muzibelesyo zilimbuli zibelesyo zyakupima muya, zibelesyo zyakutumizya, zibelesyo zyakupima kupya, zibelesyo zyakupima maanzi, zibelesyo zyakutola zitondezyo. Ma Actuators, positioners alimwi a limit switches zijisi ma spring ziyoofwambaanya kubola, alimwi zibelesyo zyakubikkila, zibelesyo zyakujatilila alimwi azijatikizyidwe ziyoovwunguluka akuleka kubeleka akaambo kakuzungaana.
Kubola kwa fretting, ooko kuchitika aakati kazyintu zizwide zizungaana, nchintu chidumide afwaafwi amavalvu aa cavitation. Eezi zipa kuti kube ma oxide mayumu mbuli zintu zikwabilila kufwambaanya kubola aakati kazintu zisofweede. Zibelesyo zijatikizyidwe zibikkilizya mavalvu aakukwabilila akulanga, kunze lyamavalvu aakweendelezya, mapompi, zipekupeku zizyunguluka, zibelesyo zyakusampula azimwi nzila zizyunguluka naa kuseluka.
Kuzungaana kupati kulakonzya kutyolaula akubola zibeela zyamavuluvu aabutale amalambo aamapaipi. Zibeela zyabutale zilimwaikide naakuti misamu iikola ilakonzya kusofwaazya zintu zili mumupayipi, zikonzya kuba ampindu mpati kukusalala kwamapayipi aamapaipi aasalala. Eezi azyalo tazizumizigwi pe.
Kuyeyela kwakubula nguzu kwamavalvu aapulagi nchintu chiyumu alimwi tachili buyo chakubalilwa kudonkola kwanguzu zyakutontola. Zyakachitika zitondezya kuti zilakonzeka kuti muya uuli mumulonga mupati ulaseluka kusika kumuwo wamaanzi kakutanaba busi bwabusena oobo akuwida kwabuumba bwamuwo. Bamwi basikupanga mavwili balaambilizya kuti zuba lilakonzya kubula chiindi chilamfu kwiinda mukupandulula kucheya kwanguzu zyakunyonyooka. Nzila yabasikupanga mavalvu yakutalisya akuyeeyela kunyonyooka kwa cavitation iyeeme akuti mabbubbu aamuwo alawida ansi, akupa kuti kube cavitation alimwi amuzuzumo. Kwakazyibwa kuti kunyonyooka kupati kwakuzwa mujulu kuyootantamukwa kuti muzuzumo uubalilwa uli munsi aazyeelelo zilembedwe munsi.
Bupati bwavalvu busika ku 3 inches – 80 dB
Bupati bwavalvu bwa 4-6 inches – 85 dB
Bupati bwavalvu 8-14 inches – 90 dB
Bupati bwamavalvu aali 16 inches kuya kumbele – 95 dB
Nzila zyakugwisya kunyonyooka kwa cavitation
Bupange bwavalvu bulibedelede bwakugwisya kuvwundauka bubelesya nzila yakugwisya maanzi akuseluka kwanguzu:
"Kusanduka kwa valve" nkukwaandaanya maanzi manji kuba tuniini tunji, mpawo nzila ya valve yakapangwa kuti maanzi azwe mumasena masyoonto aakozyenye. Mbwaanga chibeela cha bupati bwa bubble bwa cavitation chibalilwa kwiinda mumulyango oomo maanzi moinda. Ikujula kusyoonto kupa kuti kube mabbubbu masyoonto, kupa kuti kutabi muzuzumo muniini akunyonyoona kusyoonto aawo nokwaba kunyonyooka.
"Kudonkola kwanguzu" chaamba kuti vvalavu yakapangwa kuti ibe amasena obile naa kwiinda waawo aakucinca, aboobo muciindi chakudonkola koonse muchiimo chomwe, chitola ntaamu ziniini. Kuceya kwakudonkola kwanguzu zyamuntu omwe-omwe kulakonzya kulesya nguzu zyakuceya kuzwa kukuwa kwanguzu zyamuwo zyamaanzi, aboobo kugwisya cintu cicitika cakuvwundauka kwamuwo.
Kusanganya kwakuleya akudonkola kwanguzu mubbokesi lyomwe kupa kuti kube kukwabililwa kwakuvwundauka. Muchiindi chakucinca vvalavu, kubikka vvalavu yeendelezya mpawo muya wakunjilila vvalavu ulaajulu (nkokuti kulubazu lwamulonga, naa munsi-munsi), chimwi chiindi eezi zigwisya mapenzi aakuvwundauka.
Mukuyungizya, kubikka vvalavu yeendelezya abusena bwakupya kwamaanzi, aboobo muya uutontola (mbuli kupya kusyoonto) kulakonzya kugwasya kugwisya mapenzi aakupya.
Mubufwaafwi, kwakatondezya kuti kuvwundauka kwamavwili takuli buyo aatala akunyonyooka kwamavwili. Mipaipi yamaanzi azibelesyo azyalo zili muntenda. Kuyeyela kuchisa akubweza ntaamu zyakuchigwisya njenzila ilikke yakutantamuka penzi lyakubelesya mali manji kapati.
