Yintoni iValve yeNdlela Ezintathu?

AIvalvu Yeendlela Ezintathuluhlobo lwevalvu yemizi-mveliso eneezibuko ezintathu ngaphakathi emzimbeni wayo. Ezi zibuko zenza kube lula ukuqhagamshela imibhobho emithathu eyahlukeneyo, zivumela ivalvu ukuba ilawule indlela yokuhamba phakathi kwazo. Ngokungafaniyo neevalvu ezilula zokuvula/ukuvala, umsebenzi oyintloko wevalvu eneendlela ezintathu kukutshintsha indlela yokuhamba, ukuxuba ukuhamba okuvela kwimithombo emibini, okanye ukwahlula ukuhamba kube yimijelo emibini.

Iintlobo eziqhelekileyo ezifumaneka kwiinkqubo zemibhobho yemizi-mveliso ziqukaIivalvu zeBhola zeNdlela ezintathu, Iivalvu Zokulawula Iindlela Ezintathu (okanye iivalvu ezilawulayo), kunye neeValvu zeGlobe zeNdlela Ezintathu. Uhlobo ngalunye lwenziwe ngeendlela ezahlukeneyo zangaphakathi—ezifana nebhola ejikelezayo okanye isiqu sokuphakamisa—ukufezekisa umsebenzi wokulawula ukuhamba kwamanzi ofunekayo, okuzenza zifaneleke kuluhlu olubanzi lwezicelo ukusuka kwi-plumbing ngokubanzi ukuya kwi-automation yenkqubo enzima.

Isebenza njani iValve yeNdlela Ezintathu?

Ukusebenza kwevalvu eneendlela ezintathu kuxhomekeke ekuhambeni kwenxalenye yangaphakathi (njengebhola, iplagi, okanye iplagi yeglobe) xa kuthelekiswa nezihlalo zevalvu. Olu hambo lutshintsha iindlela eziphakathi kwezi zikhumbi zintathu, lulawula ngempumelelo indlela yolwelo. Ngokusekelwe kumsebenzi wazo, zahlulwe zibe ziintlobo ezimbini:

Ivalvu Yokuxuba (Ii-Inlets ezimbini, I-Outlet enye)

Olu lwakhiwo luneeport ezimbini zokungena (umz., A kunye no-B) kunye neport enye yokuphuma eqhelekileyo (C). Indawo yevalvu ilawula umlinganiselo wemidiya engena kwii-inlet ezimbini, ezixutywa ngaphambi kokuba zikhutshwe kwi-outlet (C).

• Umzekelo: Kwiinkqubo ze-HVAC, iValve yoLawulo lweNdlela ezintathu isetyenziswa rhoqo ukuxuba imijelo yamanzi abandayo nashushu ukuze kufezekiswe ubushushu obuchanekileyo bokukhupha umbane kulawulo lwemozulu39.

Ivalvu yokujika (Ukungena okuNye, iiNdawo zokuPhumla ezimbini)

Olu qwalaselo lunesango elinye eliqhelekileyo lokungena (A) kunye nesango ezimbini zokuphuma (B kunye no-C). Intshukumo yesiseko sevalvu iqondisa ukuhamba okungenayo ukusuka kwisango elinye (A) ukuya kwenye yeendawo ezimbini zokuphuma (B okanye C) okanye iyahlulahlula ngokulinganayo phakathi kwazo zombini.
