Ilungu ngalinye leqela lethu elikhulu lenzuzo yokusebenza kakuhle lixabisa iimfuno zabathengi kunye nonxibelelwano lombutho malungaIvalvu Yokukhupha Umoya, Sifumene udumo oluhle phakathi kwabathengi bamanye amazwe nabasekhaya. Silandela umgaqo-nkqubo wolawulo othi "inkonzo egxile kwityala, umthengi kuqala, ukusebenza kakuhle kunye neenkonzo ezivuthiweyo", samkela ngokufudumeleyo abahlobo abavela kuzo zonke iinkalo zobomi ukuba basebenzisane nathi.

Inkcazo:

Ivalvu yokukhupha umoya edibeneyo enesantya esiphezulu idityaniswe neenxalenye ezimbini zevalvu yomoya yediaphragm enoxinzelelo oluphezulu kunye nevalvu yokungena kunye nevalvu yokukhupha umoya esezantsi, inemisebenzi yokukhupha umoya kunye neyokungenisa umoya.
Ivalvu yokukhupha umoya we-diaphragm enoxinzelelo oluphezulu ikhupha ngokuzenzekelayo inani elincinci lomoya oqokelelene kumbhobho xa umbhobho uphantsi koxinzelelo.
Ivalvu yokungenisa umoya kunye neyokukhupha umoya enoxinzelelo oluphantsi ayinakukhupha umoya kuphela kumbhobho xa umbhobho ongenanto uzaliswe ngamanzi, kodwa naxa umbhobho uphumile okanye uxinzelelo olubi luvela, njengaxa imeko yokwahlulwa kwekholamu yamanzi, iya kuvula ngokuzenzekelayo ize ingene kumbhobho ukuze kususwe uxinzelelo olubi.

Omnye wemisebenzi ephambili yevalvu yomoya kukukhupha umoya ovalelekileyo kwinkqubo. Xa ulwelo lungena kwimibhobho, umoya unokubanjwa kwiindawo eziphakamileyo, ezinje ngamagophe, iindawo eziphakamileyo, kunye neencopho zeentaba. Njengoko ulwelo luhamba ngemibhobho, umoya unokuqokelelwa uze wenze iipokotho zomoya, nto leyo enokubangela ukuba ukusebenza kakuhle kunciphe kwaye uxinzelelo lunyuke.

Iivalvu zokukhupha umoya, njengezinye zeTWS Valveii-vavlves zebhabhathane ezihleli ngerabha, ikwadlala indima ebalulekileyo ekugcineni ukusebenza kakuhle nokusebenza kakuhle kwemibhobho neenkqubo ezithwala ulwelo. Ukukwazi kwazo ukukhulula umoya ovalelekileyo nokuthintela iimeko zokukhupha umoya kuqinisekisa ukusebenza kakuhle kwenkqubo, kuthintela ukuphazamiseka kunye nomonakalo. Ngokuqonda ukubaluleka kweevalvu zomoya kunye nokuthatha amanyathelo afanelekileyo okufakela nokugcina, abaqhubi beenkqubo banokuqinisekisa ukuba imibhobho neenkqubo zabo zihlala ixesha elide kwaye zithembekile.

Iimfuno zokusebenza:

Ivalvu yokukhupha umoya ophantsi (ifloat + uhlobo lokudada) izibuko elikhulu lokukhupha umoya liqinisekisa ukuba umoya ungena kwaye uphuma ngesantya esiphezulu sokuhamba komoya ophumayo ngesantya esiphezulu, nokuba umoya ophumayo ngesantya esiphezulu uxutywe nenkungu yamanzi, awuyi kuvala izibuko lokukhupha umoya kwangaphambili. Izibuko lomoya liza kuvalwa kuphela emva kokuba umoya uphumile ngokupheleleyo.
Ngalo naliphi na ixesha, logama nje uxinzelelo lwangaphakathi lwenkqubo luphantsi kunoxinzelelo lomoya, umzekelo, xa ukwahlulwa kwekholamu yamanzi kwenzeka, ivalvu yomoya iya kuvulela umoya ngoko nangoko kwinkqubo ukuthintela ukuveliswa kwe-vacuum kwinkqubo. Kwangaxeshanye, ukungena komoya ngexesha elifanelekileyo xa inkqubo ikhupha umoya kunokukhawulezisa isantya sokukhupha umoya. Umphezulu wevalvu yokukhupha umoya uxhotyiswe ngepleyiti yokulwa nokucaphukisa ukuze ithambe inkqubo yokukhupha umoya, enokuthintela ukutshintsha koxinzelelo okanye ezinye izinto ezitshabalalisayo.
Ivalvu yokukhupha umoya enoxinzelelo oluphezulu inokukhupha umoya oqokelelene kwiindawo eziphezulu kwinkqubo ngexesha apho inkqubo iphantsi koxinzelelo ukuze kuthintelwe ezi zinto zilandelayo ezinokubangela ingozi kwinkqubo: ukutshixa komoya okanye ukuvaleka komoya.
Ukwanda kokulahleka kwentloko kwenkqubo kunciphisa isantya sokuhamba kwamanzi kwaye nakwiimeko ezigqithisileyo kunokukhokelela ekuphazamisekeni ngokupheleleyo kokuhanjiswa kolwelo. Ukwandisa umonakalo we-cavitation, ukukhawulezisa ukugqwala kweendawo zesinyithi, ukwandisa ukuguquguquka koxinzelelo kwinkqubo, ukwandisa iimpazamo zezixhobo zokulinganisa, kunye nokuqhuma kwegesi. Ukuphucula ukusebenza kakuhle kokunikezelwa kwamanzi kwimibhobho.

Umgaqo wokusebenza:

Inkqubo yokusebenza kwevalvu yomoya edibeneyo xa umbhobho ongenanto uzaliswe ngamanzi:
1. Khupha umoya kumbhobho ukuze ukuzaliswa kwamanzi kuqhubeke kakuhle.
2. Emva kokuba umoya okwipayipi ukhutshiwe, amanzi angena kwivalvu yokungenisa umoya kunye neyokukhupha umoya enexinzelelo eliphantsi, kwaye ifloat iphakanyiswa yi-buoyancy ukuze ivale izibuko zokungenisa umoya kunye nezokukhupha umoya.
3. Umoya okhutshwa emanzini ngexesha lenkqubo yokuhambisa amanzi uza kuqokelelwa kwindawo ephezulu yenkqubo, oko kukuthi, kwivalvu yomoya ukuze kuthathelwe indawo amanzi okuqala emzimbeni wevalvu.
4. Xa umoya uqokelelana, inqanaba lolwelo kwivalvu yokukhupha umoya ezenzekelayo enoxinzelelo oluphezulu liyehla, kwaye nebhola edadayo nayo iyehla, itsala i-diaphragm ukuze ivale, ivule i-exhaust port, kwaye ikhuphe umoya.
5. Emva kokuba umoya ukhutshiwe, amanzi angena kwakhona kwivalvu yokukhupha umoya enomxinzelelo ophezulu, ayidada ibhola edadayo, aze ayivale i-port yokukhupha umoya.
Xa inkqubo isebenza, la manyathelo angentla 3, 4, 5 aya kuqhubeka nokujikeleza
Inkqubo yokusebenza kwevalvu yomoya edibeneyo xa uxinzelelo kwinkqubo luphantsi koxinzelelo kunye noxinzelelo lomoya (oluvelisa uxinzelelo olubi):
1. Ibhola edadayo yevalvu yokungenisa umoya kunye neyokukhupha umoya ephantsi iya kuwa ngoko nangoko ukuze ivule izibuko zokungenisa umoya kunye nezokukhupha umoya.
2. Umoya ungena kwinkqubo ukusuka kweli nqanaba ukuze uphelise uxinzelelo olubi kwaye ukhusele inkqubo.
