Feela joalokaha molumo o ka ba le phello e mpe 'meleng oa motho, maqhubu a itseng a ka senya lisebelisoa tsa indasteri ha valve ea taolo e khethiloe hantle, ho na le kotsi e eketsehileng ea ho phatloha ha molumo, e leng se tla lebisa lerata le phahameng le maemo a ho thothomela, e leng se fellang ka tšenyo e potlakileng haholo liphaepheng tsa ka hare le tse tlase tsavalafo.
Ho phaella moo, maemo a lerata a phahameng hangata a baka ho thothomela ho ka senyang liphaephe, lisebelisoa le lisebelisoa tse lingValveHa nako e ntse e feta, ho senyeha ha dikarolo, ho ruruha ha valve ho bakwang ke sistimi ya diphaephe e sekametseng tshenyong e kgolo.

Leha sena hangata se etsahala bolongli-valvele di-valve tse potolohang mmeleng, e ka etsahala ka nako e kgutshwane, e phahameng e tshwanang le karolo ya mmele wa wafer ya V-ball.valafohaholo-hololi-valve tsa serurubelelehlakoreng le ka tlase la valve havalafoe hatelloa boemong bo le bong e sekametseng ho cavitation, e leng se ka bakang ho dutla ha diphaephe tsa valve le tokiso ya ho tjheseletsa, valve ha e a lokela karolo ena ya mola.
Ho sa tsotelehe hore na ho phatloha ha motlakase ho etsahala ka hare ho valve kapa ka tlase ho valve, lisebelisoa tse sebakeng sa ho phatloha ha motlakase li tla senyeha haholo ke lifilimi tse tšesaane haholo, li-spring le mehaho ea cantilever e nyenyane, ho thothomela ho hoholo ha amplitude ho ka baka ho sisinyeha. Lintlha tse hlolehang khafetsa li fumanoa lisebelisoa tse kang likhakanyo tsa khatello, li-transmitter, li-sleeve tsa thermocouple, li-flowmeter, litsamaiso tsa ho etsa lisampole. Li-Actuator, li-positioner le li-switch tsa moeli tse nang le li-spring li tla senyeha ka potlako, 'me li-bracket tse hokelang, li-fasteners le li-connectors li tla hlepha le ho hloleha ka lebaka la ho thothomela.
Ho bola ha fretting, ho etsahalang pakeng tsa libaka tse tsofetseng tse pepesehetseng ho thothomela, ho atile haufi le li-valve tsa cavitation. Sena se hlahisa li-oxide tse thata e le li-abrasives ho potlakisa ho tsofala pakeng tsa libaka tse tsofetseng. Lisebelisoa tse amehileng li kenyelletsa li-valve tse arohaneng le tse hlahlobang, ho phaella ho li-valve tsa taolo, lipompo, li-screen tse potolohang, li-samplers le mokhoa ofe kapa ofe o potolohang kapa o thellang.
Ho thothomela ha bophahamo bo phahameng ho ka boela ha petsoha le ho senya likarolo tsa valve tsa tšepe le mabota a liphaephe. Likaroloana tsa tšepe tse hasaneng kapa lisebelisoa tsa lik'hemik'hale tse senyang li ka silafatsa mecha ea phatlalatso e ka har'a phaephe, e leng se ka bang le tšusumetso e kholo holim'a liphaephe tsa valve tse hloekileng le mecha ea phatlalatso ea liphaephe tse hloekileng haholo. Sena le sona ha sea lumelloa.
Ho bolela esale pele hore cavitation e hloleha ha di-valve tsa polaka ho rarahane haholo mme ha ho balwe feela ho theoha ha kgatello ya choke. Phihlelo e bontsha hore ho ka etsahala hore kgatello e molapong o moholo e theohele kgatellong ya mouoane wa mokelikeli pele ho mouoane wa sebaka seo le ho putlama ha bubble ya mouoane. Bahlahisi ba bang ba di-valve ba bolela esale pele ho hloleha ha phifalo ya letsatsi pele ho nako ka ho hlalosa tshenyo ya pele ya tshenyo. Mokgwa wa moetsi wa di-valve wa ho qala ka ho bolela esale pele tshenyo ya cavitation o itshetlehile tabeng ya hore di-bubble tsa mouoane di a putlama, e leng se bakang cavitation le lerata. Ho fumanwe hore tshenyo e kgolo ya cavitation e tla qojwa haeba boemo ba lerata bo balwang bo le ka tlase ho meedi e thathamisitsweng ka tlase.
Boholo ba valve ho fihlela ho lisenthimithara tse 3 - 80 dB
Boholo ba valve ea lisenthimithara tse 4-6 - 85 dB
Boholo ba valve 8-14 inches - 90 dB

Mekhoa ea ho felisa tšenyo ea cavitation
Moralo o khethehileng oa li-valve ho felisa cavitation o sebelisa phallo e arohaneng le ho theoha ha khatello ka maemo:
"Ho fapoha ha di-valve" ke ho arola phallo e kgolo ka diphallo tse mmalwa tse nyane, mme tsela ya phallo ya valve e entswe ka tsela eo phallo e phallang ka hara masoba a manyane a bapileng. Kaha karolo ya boholo ba bubble ya cavitation e balwa ka lesoba leo phallo e fetang ho lona. Lesoba le lenyenyane le nolofalletsa di-bubble tse nyane, e leng se fellang ka lerata le fokolang le tshenyo e fokolang ha ho tluwa tshenyong.
"Ho theoha ha khatello ka maemo" ho bolela hore valve e etselitsoe ho ba le lintlha tse peli kapa ho feta tsa tokiso ka tatellano, kahoo ho e-na le ho theoha ha khatello eohle mohatong o le mong, e nka mehato e 'maloa e menyenyane. Ho theoha ha khatello ka tlase ho ka thibela khatello e honyelang khatellong ea mouoane ea mokelikeli o oang, ka hona ho felisa ketsahalo ea cavitation ka har'a valve.
Motsoako oa ho fapoha le ho theola khatello ka har'a valve e le 'ngoe o lumella khanyetso e ntlafetseng ea cavitation ka. Nakong ea phetoho ea valve, ho beha valve ea taolo le khatello ho kenoeng ha valve ho phahame (mohlala, lehlakoreng le holimo, kapa bophahamong bo tlase), ka linako tse ling ho felisa mathata a cavitation.
Ho phaella moo, ho beha valve ea taolo sebakeng sa mocheso oa mokelikeli, ka hona khatello e tlase ea mouoane (joalo ka mocheso o tlase oa lehlakore la mocheso) ho ka thusa ho felisa mathata a cavitation.
Kakaretso e bontšitse hore ketsahalo ea cavitation ea li-valve ha e le hantle ha se feela ka ts'ebetso ea ho senyeha le tšenyo ea li-valve. Liphaephe le lisebelisoa tse theohelang le tsona li kotsing. Ho bolela esale pele cavitation le ho nka mehato ea ho e felisa ke eona feela tsela ea ho qoba bothata ba litšenyehelo tse turang tsa tšebeliso ea li-valve.
