Yintoni ivalve yebhabhathane?
A ivelufa butterflyyivalve yekota. Isetyenziselwa ukulawula okanye ukwahlula ukuhamba kwamanzi kwimibhobho. Ivalve yebhabhathane nangenxa yoyilo lwayo olulula kunye nokusebenza kakuhle nangazo zonke iinkalo zobomi.
Imvelaphi yegama levalve yebhabhathane: i-valve flap imile okwebhabhathane kwaye ithiywe njalo.
1. Isakhiwo
Ivalve yebhabhathane inala malungu alandelayo:
- Umzimba: indlu ebamba onke amalungu angaphakathi kwaye iqhagamshele kumbhobho.
- Idiskhi: yipleyiti engqukuva engqukuva ngaphakathi kwivalve yomzimba, elawula ukuhamba kolwelo ngokujikeleza.
- Isiqu: I-shaft edibanisa i-actuator kwi-flap yevalve kwaye iyivumele ukuba ijikeleze.
- Isitulo: Indawo yokutywina ngaphakathi kumzimba wevalvu, apho iflapper icinezela isihlalo ukuze yenze itywina le-hermetic xa ivaliwe ukumisa ukuphuma kwamanzi.
-I-Actuator: Ii actuator ezisetyenziswa ngesandla ezifana nezibambo, iigiya zeentshulube, kodwa kunye nombane kunye ne-pneumatic.
Ezi zixhobo zidibanisa ukwenza i-valve edibeneyo, ekhaphukhaphu elula ukuyifaka kunye nokugcina.

2. Umgaqo wokusebenza
Ukusebenza kwevalve yebhabhathane kusekelwe kwi-torque kunye ne-hydrodynamics. Imfuno ye-torque iyahluka ngokuxhomekeke kumahluko woxinzelelo phakathi kwamacala amabini evalve yebhabhathane kunye nendawo ye-valve flap. Kuyathakazelisa ukuba i-torque iphezulu kwi-70-80% yokuvula i-valve ngenxa ye-torque eguquguqukayo yolwelo. Olu phawu lufuna uthelekiso lwe-actuator oluchanekileyo.
Ukongeza, iivalve zebhabhathane zineepesenti ezilinganayo zokuqukuqela kophawu lwegophe, okuthetha ukuba uhlengahlengiso oluncinci kwiflap lunefuthe elikhulu kakhulu kwisantya sokuhamba kwimivulo yevalvu ephantsi kunokuba kufutshane nokuvuleka okugcweleyo. Oku kwenza ukuba iivalvu zebhabhathane zifanelekele ngokufanelekileyo ulawulo lwe-throttling kwiimeko ezithile, ngokuchasene nenkolelo eqhelekileyo yokuba zilungele ukusetyenziswa kuphela / ukuvala.
Iivalve zebhabhathane zilula kwaye zisebenza ngokufanelekileyo:
- Indawo evulekileyo: i-valve flap ijikeleziswa ngokuhambelana necala lolwelo, ivumela ulwelo ukuba ludlule phantse ngaphandle kokuphikiswa.
- Isikhundla esivaliweyo: i-valve ijikeleza i-perpendicular ukuya kwicala le-fluid, ivala ngokupheleleyo i-fluid.
Njengevalve yekota yokujika, itshintsha phakathi kokuvula ngokupheleleyo kwaye ivalwe ngokupheleleyo ngokujikeleza kuphela i-90 degrees, ngokukhawuleza nangokufanelekileyo.

3. Izinto eziluncedo nezingeloncedo
3.1 Izinto eziluncedo kwiivalvu zebhabhathane
-Icwecwe kwaye ikhaphukhaphu: Incinci kwaye kulula ukuyifaka kunezinye iivalvu ezifana nesango okanye iivalvu zeglowubhu.
- Uqoqosho kunye nokusebenza kakuhle: ixabiso eliphantsi ngenxa yokwakhiwa okulula kunye nezinto ezincinci.
- Ukukhawuleza ukusebenza: inokuvulwa okanye ivalwe ngokujika kwekota, ilungele ukuphendula ngokukhawuleza kwimfuno.
- Iindleko zokulondolozwa okuphantsi: iindawo ezincinci ezihambayo zithetha ukuguga kunye nokukrazula kunye nokugcinwa okulula.
3.2 Izinto ezingeloncedo kwiivalvu zebhabhathane
- I-throttling ethintelweyo: ayifanelekanga ukulawula ukuhamba okuchanekileyo, ngakumbi kuxinzelelo oluphezulu, njengoko kunokukhokelela kwisiphithiphithi kunye nokuguga.
- Umngcipheko wokuvuza: ezinye iziyilo azinakutywinwa ngokuqinileyo njengezinye iindidi zeevalvu kwaye kukho umngcipheko wokuvuza.
- Ukwehla koxinzelelo: nangona xa kuvuliwe, i-valve flap ihlala kwindlela yokuhamba, okubangela ukunciphisa uxinzelelo oluncinci.

4. Izicelo
Iivalvu zebhabhathane zisetyenziswa kakhulu kumashishini amaninzi ngenxa yokukwazi kwabo ukulawula umthamo omkhulu wolwelo kunye nelahleko encinci yoxinzelelo, zizenza zilungele imibhobho emikhulu.
Umzekelo:
- Ukucocwa kwamanzi: ukulawula ukuhamba kwamanzi kwiindawo zokunyanga amanzi kunye nothungelwano lokuhambisa.
- Iinkqubo ze-HVAC: ukulawula ukuhamba komoya ekufudumeni, ukungena komoya kunye neenkqubo zomoya.
- Ukulungiswa kweekhemikhali: Ingasetyenziselwa ukuphatha uluhlu olubanzi lweekhemikhali ngenxa yokuhambelana kwezinto.
- Ukutya kunye neSiselo: kwiinkqubo zococeko ngenxa yokucoca lula.
- I-oyile kunye negesi: ilawula kwaye ihlukanise ukuhamba kwimibhobho kunye nokucoca.
