I-Venturi Tube Butterfly Valve: Ukulawulwa Kokugeleza Okusebenza Kakhulu kanye Nezicelo Ze-Carb

Iyini ithubhu yeVenturi

I-Venturi tube, eyaziwa nangokuthi i-Venturi tube noma i-Venturi nozzle, iyithuluzi elisetshenziselwa ukukala umehluko wokucindezela koketshezi. Isebenzisa isimiso se-Bernoulli kanye ne-Cauchy equation ku-continuous fluid dynamics ukukhiqiza umehluko wokucindezela lapho uketshezi ludlula ezimweni eziklanyelwe ngokukhethekile zokufinyela kanye nokwanda epayipini, futhi iguqula lo mehluko wokucindezela ube yinani lokulinganisa izinga lokugeleza kanye nezinga lokugeleza.

Isimiso sokusebenza seVenturi Tube

Ipayipi le-Venturi lakhiwe ipayipi elide eliyindilinga elinesigaba sokugoba phakathi kwepayipi. Uketshezi luyanda ngesivinini futhi luyancipha ekucindezelweni lapho ludlula kulesi sigaba sokugoba; bese kancane kancane lubuyela esimweni salo sokuqala esigabeni sokunwebeka. Ngokulinganisa umehluko wokucindezela phakathi kwesigaba sokugoba kanye nesigaba sokunwebeka, izinga lokugeleza kanye nezinga lokugeleza koketshezi kungatholakala.

Izinhlobo zama-valve ku-Venturi Tube

Izinhlobo zama-valve kumapayipi e-Venturi zifaka phakathi okulandelayo:

I-valve yevolumu yomoya engaguquki:

Umsebenzi waleli valuvu ukugcina ukugeleza komoya okuzinzile.

I-valve egobekayo:

Ingashintsha ukuze inikeze amazinga okugeleza komoya amabili ahlukene, okungukuthi izinga lokugeleza eliphezulu kanye nezinga eliphansi lokugeleza.

‌

I-valve yomoya eguquguqukayo:

Inokusabela okuphezulu, ingaphendula imiyalelo kungakapheli umzuzwana owodwa, futhi ifinyelele ukulawulwa okuvaliwe ngezibonakaliso zempendulo yokugeleza, ngaleyo ndlela ilungise ngokunembile ukugeleza komoya.
Isimiso sokusebenza sala ma-valve sisekelwe kumphumela we-Venturi, okungukuthi, lapho umoya ugeleza nge-valve, indawo yawo yokuvula izozivumelanisa ngokuzenzakalelayo ngokwezinga lokugeleza, ukuze kufezwe ukulawula okuningiliziwe kokugeleza komoya. Umphumela we-Venturi ubhekisela eqinisweni lokuthi ngemva kokuba umoya udlule epayipini elincipha kancane kancane, izinga lokugeleza lizokhula kakhulu, futhi ingcindezi izoncipha, ngaleyo ndlela kufezwe ukulawula okunembile kokugeleza komoya.

Kungani ukhethe i-butterfly valve njenge-Venturi Tube Valve

Izizathu zokukhetha i-butterfly valve njenge-Venturi Tube Valve zifaka phakathi okulandelayo:

Ukusebenza kahle kwezindlekoIzindleko zevalvu yebhabhathane ziphansi kakhulu, ngokuvamile cishe ingxenye eyodwa kwezine yevalvu yeVenturi. Lokhu kuyinto ebalulekile okufanele icatshangelwe uma isabelomali silinganiselwe.

Ukungalingani kolwazi lobuchwepheshe: Abasebenzisi abaningi emakethe abanalo ukuqonda okwanele ngezici zobuchwepheshe zama-valve e-Venturi nama-valve e-butterfly, okuholela ekudingweni okukhulu kwama-valve e-butterfly emakethe.

Izidingo zemvelo eziphansiKwezinye izimo lapho izidingo zokulawula imvelo zingekho phezulu, ama-valve e-butterfly asebenza kahle ngokuphelele futhi ngenxa yalokho asetshenziswa kabanzi.

Ukufakwa okulula nokugcinwa: I-valve ye-butterfly inesakhiwo esilula, isikhala esincane sokufakwa, isisindo esincane, kanye nokulungiswa okulula, okufanelekela izikhathi ezidinga ukufakwa nokulungiswa okusheshayo ‌.

Yiziphi izinhlobo zama-Venturi Tube Butterfly Valve

Izinhlobo zeAmavalvu e-Venturi Tube Butterflyikakhulukazi zifaka okulandelayo:

I-valve yebhabhathane yohlobo lwe-Wafer:

Ekwakhiweni kwevalvu yebhabhathane yohlobo lwe-wafer, ipuleti lebhabhathane lifakwa eceleni kobubanzi bepayipi ukuqinisekisa ukuthi ivalvu ihlala ivulekile ngokuphelele. Lo mklamo unesakhiwo esilula, indawo encane, kanye nesisindo esincane. Ivalvu yebhabhathane yohlobo lwe-wafer inikeza izindlela ezimbili zokuvala: ukuvala okunwebekayo kanye nokuvala insimbi, ezifanele izimo ezahlukahlukene zokusetshenziswa ‌.

I-valve yebhabhathane yohlobo lwe-Flange:

I-valve yebhabhathane yohlobo lwe-flange isebenzisa umklamo wepuleti eliqondile, kanti isiqu se-valve siyisakhiwo sensimbi esibalulekile ukuqinisekisa ukuqina kwe-valve. Indandatho yayo yokuvala isebenzisa indandatho yokuvala ehlanganisiwe yepuleti le-graphite eliguquguqukayo kanye nepuleti lensimbi engagqwali, elifanelekela imidiya ehlukahlukene. Ama-valve ebhabhathane yohlobo lwe-flange afaneleka ngezikhathi ezidinga ukuqina okuphezulu kanye nomphumela wokuvala ‌. ‌ ‌

I-valve yebhabhathane ehlanganisiwe:

I-valve ye-butterfly ehlanganisiwe iyi-valve ye-butterfly engavaliwe efanelekela izinto zokwakha, i-metallurgy, i-mining kanye namandla. Ifanele amapayipi anezinga lokushisa eliphakathi elingadluli ku-300°C kanye nomfutho ojwayelekile ongu-0.1MPa, futhi ingafinyelela ukuxhumana okuphakathi, ukuvulwa nokuvalwa noma ukulawulwa.

I-valve yebhabhathane enentambo:

Umzimba wevalvu yevalvu yebhabhathane enezintambo unikezwa imicu yangaphakathi noma yangaphandle, elula ukuxhuma nemicu yepayipi. Le valve yebhabhathane isetshenziswa kabanzi ezintweni zokwakha, ukusansimbi, ukumbiwa kwemigodi kanye namandla.

I-Clamp butterfly valve:

I-clamp butterfly valve ine-reducer ekwakhiweni kwayo ukuze ithuthukise ukusebenza kwayo futhi ifanele amapayipi amakhulu. Umzimba wayo we-valve wenziwe ngensimbi yekhabhoni ecwengekile, kanti indandatho yokuvala yenziwe ngendandatho yensimbi, efanelekile ngezikhathi ezidinga ukusebenza njalo noma umfutho ophezulu.

Lezi zinhlobo ezahlukene zeAmavalvu ebhabhathane e-Venturi tubebanezimpawu zabo kanye nezimo ezifanele. Abasebenzisi bangakhetha uhlobo olufanele ngokwezidingo ezithile.
