Khaolo ea 1 - Valve ea ho Hlahloba ea Selemo ke eng?
Valve ea tlhahlobo ea selemo ke valve e netefatsang phallo ea tsela e le 'ngoe le ho thibela phallo e khutlelang morao. Li na le sebaka sa ho kena le ho tsoa 'me li tlameha ho beoa ka tsela e nepahetseng hore li sebetse hantle. Ka lehlakoreng la li-valve tsa tlhahlobo ea selemo le li-valve tsohle tsa tlhahlobo, ho na le motsu o supang lehlakoreng la phallo. Valve ea tlhahlobo e jereng selemo e bitsoa valve ea tsela e le 'ngoe kapa valve ea tsela e le 'ngoe. Morero oa valve ea tlhahlobo ea selemo ke ho sebelisa spring le khatello e sebelisoang ho disc ho emisa phallo e khutlelang morao ho koala valve.

E le hore valve ea ho hlahloba e sebetse hantle, e tlameha ho ba le khatello e fapaneng, e phalle ho tloha khatellong e phahameng ho ea khatellong e tlase. Khatello e phahameng kapa khatello e petsohang lehlakoreng la ho kena e lumella mokelikeli ho phalla ka har'a valve le ho hlola matla a selemo ka har'a valve.

Ka kakaretso, valve ea ho hlahloba ke sesebelisoa se lumellang mofuta ofe kapa ofe oa mecha ea phatlalatso ho phalla ka lehlakoreng le le leng. Sebopeho sa mokhoa oa ho hlahloba e ka ba selika-likoe, disc, piston kapa poppet, hlooho ea li-mushroom. Li-valve tsa ho hlahloba tsa selemo li thibela phallo e khutlelang morao e le mokhoa oa ho sireletsa lipompo, lisebelisoa le mechini ha khatello tsamaisong e qala ho fokotseha, ho lieha, ho ema kapa ho khutlela morao.

Li-valve tsa ho hlahloba ho tjheka di dumella phallo ya tsela e le nngwe mme di kwala ka boiketsetso ha kgatello ya ho petsoha e fokotseha. Ke mofuta wa valve ya serurubele e nang le diski e kwahelang lesoba la valve. Puck e hoketswe ho hinge e le hore ha e otlwa ke phallo ya media, puck e ka buleha kapa ya kwala. Motsu o ka lehlakoreng la mmele wa valve o bontsha tsela eo mokelikeli o kenang le ho tswa ka yona ho valve.

Boemo ba kgatello ya mokelikeli bo sutumelletsa diski kapa lemati ho buleha, e leng se dumellang mokelikeli ho feta. Ha phallo e tsamaya ka tsela e fosahetseng, diski e a kwala ka lebaka la ho sutumetswa ha mokelikeli kapa mokedi.

Valve ea ho hlahloba ho chechela

Li-valve tsa ho hlahloba ho thekesela ha li hloke matla a kantle. Ho feta ha metsi kapa mecha ea phatlalatso ka har'a tsona ha ho sitisoe ke boteng ba tsona. Li kentsoe ka ho otloloha liphaepheng, empa li ka kengoa ka ho otloloha ha feela phallo e le holimo.

Khaolo ea 3 - Mefuta ea Li-valve tsa ho Hlahloba tsa Spring
Hore valve ea ho hlahloba e tletseng selemo e sebetse hantle, e tlameha ho ba le khatello e holimo, e bitsoang khatello ea ho qhaqha, ho e boloka e butsoe. Bongata ba khatello ea ho qhaqha e hlokahalang bo itšetlehile ka mofuta oa valve, kaho ea eona, litšobotsi tsa selemo le tsela eo e shebaneng le eona ka har'a phaephe. ​​Litlhaloso tsa khatello ea ho qhaqha li ka liponto ka lisenthimithara tse sekwere (PSI), liponto ka lisenthimithara tse sekwere (PSI), kapa bare, 'me yuniti ea khatello ea metric e lekana le 14.5 psi.

Ha kgatello e nyolohang e le tlase ho feta kgatello e petsohang, kgatello e ka morao e fetoha ntlha mme mokelikeli o tla leka ho phalla ho tloha sehokelong se hodima valve ho ya ho pompo. Ha sena se etsahala, valve e kwala ka boyona mme phallo e a ema.

Axial phallo khutsitseng cheke valve
Ka valve e hlahlobang phallo e sa sisinyeheng ea axial flow, poleiti ea valve e tšoaroa ke seliba se bohareng ba poleiti ea valve bakeng sa phallo e boreleli le ho buloa le ho koaloa hang-hang. Seliba le disc li bohareng ba phaephe, 'me mokelikeli o phalla ho potoloha disc. Sena se fapane le li-valve tse sisinyehang kapa mefuta e meng ea li-valve tsa spring, tse hulang disc ka botlalo ka har'a mokelikeli, li siea tube e butsoe ka botlalo.

Moralo o ikgethang wa valve ya ho hlahloba e sa sisinyeheng ya phallo ya axial o etsa hore e be theko e boima ho feta divalve tsa ho hlahloba tsa selemo tsa setso le divalve tsa ho hlahloba swing. Le hoja di le theko e boima, puseletso ya matsete e bakwa ke nako ya tsona e telele ya bophelo, e ka nkang dilemo tse fetang tse tharo ho nkela sebaka.

Kaho e ikhethang ea Axial Flow Quiet Check Valve e u lumella ho bona ka tlase moo valve e bulehang le moo mokelikeli o phallang teng. Joalo ka li-valve tsa tlhahlobo ea selemo, li-valve tsa tlhahlobo ea axial li qala ho koala ha khatello e nyolohang e theoha. Ha khatello e fokotseha butle-butle, valve e koala butle-butle.
