Iyini ivalvu yebhabhathane?
A ivalvu yebhabhathaneiyivalvu ejika ngekota. Isetshenziselwa ukulawula noma ukuhlukanisa ukugeleza koketshezi emapayipini. Ivalvu ye-Butterfly futhi ngenxa yomklamo wayo olula kanye nokusebenza kahle kwazo zonke izigaba zokuphila.
Umsuka wegama le-butterfly valve: i-valve flap ibunjwe njenge-butterfly futhi iqanjwe kanjalo.
1. Isakhiwo
I-valve ye-Butterfly iqukethe izingxenye ezilandelayo eziyinhloko:
- Umzimba: indlu ebamba zonke izingxenye zangaphakathi futhi exhumanisa nepayipi.
- Idiski: ipuleti eliyisiyingi eliyisicaba ngaphakathi komzimba wevalvu, elilawula ukugeleza koketshezi ngokujikeleza.
- Isiqu: Umgodi oxhumanisa i-actuator ne-valve flap futhi uyivumele ukuthi ijikeleze.
- Isihlalo: Indawo yokuvala ngaphakathi komzimba wevalvu, lapho i-flapper icindezela khona isihlalo ukuze yakhe uphawu olungenamoya uma ivaliwe ukuze kumiswe ukugeleza koketshezi.
- I-Actuator: Ama-actuator esandla njengezibambo, amagiya ezikelemu, kodwa futhi kagesi kanye ne-pneumatic.
Lezi zingxenye ziyahlangana zakhe ivalvu encane, elula okulula ukuyifaka nokuyinakekela.

2. Isimiso sokusebenza
Ukusebenza kwevalvu yebhabhathane kusekelwe ku-torque kanye ne-hydrodynamics. Isidingo se-torque siyahlukahluka kuye ngomehluko wokucindezela phakathi kwezinhlangothi ezimbili zevalvu yebhabhathane kanye nendawo ye-valve flap. Ngokuthakazelisayo, i-torque ifinyelela ekuvulekeni kwevalvu okungu-70-80% ngenxa ye-torque enamandla yoketshezi. Lesi sici sidinga ukufanisa i-actuator ngendlela eqondile.
Ngaphezu kwalokho, ama-valve e-butterfly ane-curve ephawulekayo yokugeleza kwephesenti elilinganayo, okusho ukuthi ukulungiswa okuncane ku-flap kunomthelela omkhulu kakhulu esilinganisweni sokugeleza ezindaweni ezivulekile zama-valve eziphansi kunezindawo ezivulekile eziseduze. Lokhu kwenza ama-valve e-butterfly afaneleke kakhulu ekulawuleni ukugoba ezimweni ezithile, ngokuphambene nenkolelo evamile yokuthi afanelekela ukusetshenziswa kokuvula/ukuvala kuphela.
Ama-valve e-Butterfly alula futhi asebenza kahle:
- Indawo evulekile: i-valve flap ijikeleziswa ihambisana nesiqondiso soketshezi, okuvumela uketshezi ukuthi ludlule cishe lungaphikiswa.
- Indawo evaliwe: ivalvu ijikeleza ngokuqondile iqonde ohlangothini loketshezi, ivala ngokuphelele uketshezi.
Njengevalvu yokujika ngekota, ishintsha phakathi kokuvuleka ngokuphelele nokuvaleka ngokuphelele ngokujikeleza amadigri angu-90 kuphela, ngokushesha nangokusebenza kahle.

3. Izinzuzo kanye nokungalungi
3.1 Izinzuzo zamavalvu ebhabhathane
- Incane futhi ilula: Incane futhi kulula ukuyifaka kunezinye izivalo ezifana namavalvu esango noma eglobhu.
- Eyongayo futhi esebenza kahle: izindleko eziphansi ngenxa yokwakha okulula kanye nezinto zokwakha ezimbalwa.
- Isebenza ngokushesha: ingavulwa noma ivalwe ngokujika kwekota, ilungele ukuphendula ngokushesha esidingweni.
- Izindleko zokulungisa eziphansi: izingxenye ezimbalwa ezihambayo zisho ukuguguleka okuncane kanye nokulungiswa okulula.
3.2 Izinkinga zama-valve e-butterfly
- Ukugoba okulinganiselwe: akufaneleki ukulawula ukugeleza okunembile, ikakhulukazi lapho kucindezeleke kakhulu, njengoba kungaholela ekuphazamisekeni nasekugugeni.
- Ingozi yokuvuza: eminye imiklamo ingase ingavaleki kahle njengezinye izinhlobo zamavalvu futhi kunengozi yokuvuza.
- Ukwehla kwengcindezi: noma ngabe ivuliwe, i-valve flap ihlala endleleni yokugeleza, okuholela ekunciphiseni okuncane kwengcindezi.

4. Izicelo
Ama-valve e-Butterfly asetshenziswa kabanzi ezimbonini eziningi ngenxa yekhono lawo lokuphatha inani elikhulu loketshezi ngokulahlekelwa okuncane kwengcindezi, okwenza abe afaneleke kakhulu kumapayipi amakhulu.
Isibonelo:
- Ukwelashwa kwamanzi: ukuphatha ukugeleza kwamanzi ezitshalweni zokwelashwa kwamanzi kanye namanethiwekhi okusabalalisa.
- Izinhlelo ze-HVAC: lawula ukuhamba komoya ezinhlelweni zokushisa, zokungenisa umoya kanye nezokupholisa umoya.
- Ukucubungula ngamakhemikhali: Kungasetshenziswa ukusingatha izinhlobo eziningi zamakhemikhali ngenxa yokuhambisana kwezinto.
- Ukudla Neziphuzo: ngezinqubo zokuhlanzeka ngenxa yokuhlanza okulula.
- Uwoyela negesi: kulawula futhi kuhlukanise ukugeleza kwamapayipi nasezindaweni zokuhluza.

Kafushane,amavalvu ebhabhathanekuyinketho yokulawula uketshezi ewusizo futhi engabizi kakhulu, ethandwa ngobulula bayo kanye nokuguquguquka kwayo.
