Xa kufikwa kwihlabathi leevalvu zeebhabhathane zorhwebo, ayizizo zonke izixhobo ezidalwe zilingana. Kukho umahluko omkhulu phakathi kweenkqubo zokuvelisa kunye nezixhobo ngokwazo ezitshintsha kakhulu iinkcukacha kunye nobuchule. Ukuze alungiselele ngokuchanekileyo ukwenza ukhetho, umthengi kufuneka afunde itekhnoloji kunye nomahluko kuhlobo ngalunye ukuze akhethe isixhobo sakhe ngokufanelekileyo.
Zithini iiValve zeButterfly?
Ivalvu yebhabhathane sisiqwenga esithile sezixhobo ezenzelwe ukulawula ukuhamba kwayo nayiphi na into engamanzi okanye engamanzi adlula kuthotho lweepayipi. Le mibhobho inokuthutha izinto ezahlukeneyo ezifana namanzi, ioyile, amafutha, inkunkuma, okanye naluphi na olunye uhlobo lwegesi, ulwelo okanye izinto ezingamanzi angaphantsi.
Olu hlengahlengiso lokuhamba kwamanzi lwenziwa ngokusebenzisa idiski ejikelezayo ejikeleziswayo ukuze ivuleke okanye ivalwe kumphezulu wombhobho wangaphakathi. Xa idiski ijikeleziswa kwindawo ethe nkqo kwindlela engaphakathi yombhobho, ivala indlela kwaye iyeke ukuhamba kwamanzi ngokupheleleyo. Xa ijikeleziswa ukuze ibekwe ngaxeshanye nombhobho, isithintelo siyasuswa kwaye ukuhamba kwamanzi ngokupheleleyo kuyavunyelwa kwakhona. Ivalvu ingabekwa kwiindawo eziphakathi, yandise okanye inciphise indlela edlulayo ngokwandayo njengoko kuchaziwe sisixhobo sokulawula ukuhamba kwamanzi.
Ukwakhiwa kweeValve zeButterfly
Izinto zokwakha zevalvu zimisela amandla azo kunye nobude bayo. Iivalvu ezenzelwe ukuhamba ngamandla, uxinzelelo oluphezulu, kunye nokusetyenziswa ixesha elide, ingakumbi kwiindawo ezikude, zihlala zakhiwe ngentsimbi eqinisiweyo okanye eyomeleleyo. Ezinye iinguqulelo ezenzelwe ukusebenza lula okanye ukusetyenziswa kwexesha elifutshane zenziwe ngezinto ezifana ne-alloy ekhanyayo, i-aluminium, okanye iplastiki ye-PVC. Iivalvu ezikumgangatho ophezulu zenzelwe ukumelana nobunzima bokuphatha uxinzelelo oluphezulu kakhulu, zithwale ukuhamba okukhulu kwezinto, kwaye zinokuqina okufunekayo ukusetyenziswa ixesha elide. Kwizixhobo ezikwiindawo ezinzima ukufikelela kuzo okanye ezingaphantsi komhlaba, kufuneka ivalvu yesitayile esihlala ixesha elide. Iindleko zokufikelela kweso sixhobo ukuze sitshintshwe zihlala zinkulu kakhulu, ngoko ke ukutyala imali kwivalvu ekumgangatho ophezulu kwasekuqaleni lukhetho lobulumko.
Izicelo ezithile
Kubalulekile ukukhetha ivalvu ngokwesicelo esithile. Ezinye zikhaphukhaphu kwaye zenzelwe imijelo yamanzi emincinci okanye ulawulo lwemijelo yepetroli. Ii-aquarium, amachibi okudada, kunye neenkqubo zokutshiza zimizekelo emihle yokusetyenziswa okulula, okungabalulekanga kwiivalvu zebhabhathane.
Izicelo ezifuna kakhulu ezifana nemibhobho yegesi, iinkqubo zothutho lweoyile okanye iinkqubo zokutshintsha amanzi edolophini ezinoxinzelelo oluphezulu zifuna iivalvu ezisemgangathweni ophezulu nezithembekileyo ezinomjikelo wobomi obongezelelekileyo. Ezi zixhobo zinzima zivavanywa emizimbeni ukuze zikwazi ukusebenza nokuthembeka, ukuze zihlangabezane kwaye zidlule kwiimfuno zemisebenzi ebalulekileyo.
Iinkcukacha zomenzi zingatyhila iinkcukacha zezixhobo zevalvu nganye. Ukukhetha ivalvu efanelekileyo yomsebenzi kubalulekile ekusetyenzisweni ixesha elide kunye namathuba ancitshisiweyo okungasebenzi kakuhle koomatshini.
Inqanaba lokuchaneka
Enye into ebalulekileyo ekukhetheni ivalvu yokusetyenziswa linqanaba lokuchaneka eliye layilwa kwisixhobo. Ivalvu nganye ineenkcazo ezichaza ubungakanani bokuvuza, ukuba kukho, kwindawo yokuvala, ububanzi bomda, umthamo wolwelo onokudlula xa ivuliwe ngokupheleleyo, kunye nokuba ivalvu ithembeke kangakanani ixesha elide. Iinkcukacha zikwachaza isantya sokusebenza kwevalvu, zilungele iimeko apho ukusebenza ngexesha elifanelekileyo kuyimfuneko.
Iinketho zoLawulo
Into elandelayo ebalulekileyo ekukhetheni ivalvu yesicelo esithile yindlela yokulawula. Ezinye iivalvu ziquka i-lever okanye isiphatho, esenzelwe ukutshintshwa ngesandla ukusuka ekuvulekeni ukuya ekuvalekeni. Isiphatho sidla ngokuba nomjikelo wekota wokuhamba ukusuka esiphelweni ukuya esiphelweni, ukuze kutshintsheke ngokukhawuleza nangokulula imeko yevalvu. Ezinye zenzelwe ukuba zizenzekele ngokuzenzekelayo ngokusebenzisa isixhobo sokutshintsha ngoomatshini esifana ne-solenoid okanye olunye uhambo loomatshini olusebenzayo.
Iivalvu eziphucukileyo ziquka inkqubo yolawulo lwemoto yombane esebenza ngokupheleleyo. Le moto ijikeleza ngokuthe ngqo umngxuma wevalvu okanye ishukumise i-lever ngokusebenzisa ingalo ye-actuator. Nokuba yeyiphi na inika ulawulo olupheleleyo kwindawo ekude kwaye ingasetyenziselwa ukulungisa ulawulo lokuhamba kwamanzi oluchanekileyo ukuba kuyimfuneko.
Umthamo weValve
Into yokugqibela ekukhetheni ivalvu ngumthamo wesixhobo. Oku kuquka iinkcukacha zokuhamba kwamanzi malunga nokuba zingakanani izinto ezidluliselwa kwivalvu ngexesha elithile, kunye nokuba ivalvu inokunyamezela uxinzelelo lwangaphakathi ngokukhuselekileyo. Kwizixhobo ezihamba ngamandla aphezulu, kufuneka ivalvu enkulu, ekumgangatho ophezulu, enobukhulu obufanelekileyo ukuze ihambelane nenkqubo yombhobho eqhotyoshelweyo. Qiniseka ukuba ujonga iinkcukacha ngokuhambelana neemfuno zakho ezithile ukuqinisekisa ukuba ivalvu inamandla aneleyo okusetyenziswa.
Inkxaso yeeValve zeButterfly
Kwiinkqubo ezininzi, into ebalulekileyo inokuba yinkampani kunye nerekhodi yayo kubathengi. Isebe lenkxaso elinamandla kunye nenkonzo emva kokuthengisa kubalulekile ekusebenzeni kweshishini kwaye lingenza okanye liphule iinjongo zakho ngokufumaneka kwazo. Qiniseka ukuba usebenzisana nomthombo othembekileyo nothembekileyo xa ukhetha iivalvu ezilungele iimfuno zakho ezithile.
