I-Venturi Tube Butterfly Valve: Ukulawula Ukugeleza Okusebenza Kakhulu Nezicelo ZeCarb

Yini i-Venturi tube

Ishubhu ye-Venturi, eyaziwa nangokuthi i-Venturi tube noma i-Venturi nozzle, iyithuluzi elisetshenziselwa ukukala umehluko wengcindezi yoketshezi. Isebenzisa isimiso se-Bernoulli kanye ne-equation ye-Cauchy ku-dynamics ye-fluid eqhubekayo ukukhiqiza umehluko wengcindezi lapho uketshezi ludlula ekufinyezweni okuklanywe ngokukhethekile nokunwetshwa kwepayipi, futhi iguqule lo mehluko wengcindezi ube yinani lokulinganisa izinga lokugeleza kanye nezinga lokugeleza.

Isimiso sokusebenza se-Venturi Tube

Ishubhu le-Venturi liqukethe ipayipi elide eliyindilinga elinengxenye yokufinyela phakathi nendawo yepayipi. Uketshezi luyanda ngesivinini futhi luyancipha ingcindezi lapho ludlula kulesi sigaba sokufinyela; bese kancane kancane ibuyela esimweni sayo sokuqala esigabeni sokunwetshwa. Ngokulinganisa umehluko wengcindezi phakathi kwesigaba sokufinyela kanye nesigaba sokunwetshwa, izinga lokugeleza kanye nezinga lokugeleza koketshezi kungatholakala.

Izinhlobo zama-valve ku-Venturi Tube

Izinhlobo zama-valve kumapayipi e-Venturi ikakhulukazi zihlanganisa okulandelayo:

Ivalvu yevolumu yomoya engashintshi:

Umsebenzi wale valve ukugcina ukuphuma komoya okuzinzile.

I-valve ye-Bistable:

Ingashintsha ukuze inikeze amazinga okugeleza komoya amabili ahlukene, okuyisilinganiso esiphezulu sokugeleza kanye nesilinganiso esincane sokugeleza.

.

I-valve yevolumu yomoya eguquguqukayo:

Inokusabela okuphezulu, ingaphendula emiyalweni phakathi kwesekhondi elingu-1, futhi izuze ukulawulwa kwe-loop evaliwe ngamasignali empendulo yokugeleza, ngaleyo ndlela ilungise ngokunembile ukugeleza komoya.
Isimiso sokusebenza kwalawa ma-valve sisekelwe kumphumela we-Venturi, okungukuthi, lapho umoya ugeleza nge-valve, indawo yayo yokuvula izolungisa ngokuzenzakalelayo ngokuvumelana noshintsho lwezinga lokugeleza, ukuze kuzuzwe ukulawula okuningiliziwe kokugeleza komoya. Umphumela we-Venturi ubhekisela eqinisweni lokuthi ngemva kokuba umoya udlula ipayipi elincipha kancane kancane, izinga lokugeleza lizokhula kakhulu, futhi ukucindezela kuzokwehla, ngaleyo ndlela kufinyelele ukulawula okunembile kokugeleza komoya.

Kungani ukhethe i-butterfly valve njenge-Venturi Tube Valve

Izizathu zokukhetha i-valve uvemvane njenge-Venturi Tube Valve ikakhulukazi zifaka okulandelayo:

Ukusebenza kahle kwezindleko: Izindleko ze-valve uvemvane ziphansi, ngokuvamile cishe ingxenye eyodwa kwezine yaleyo ye-Venturi valve. Lokhu kubalulekile ukucatshangelwa uma isabelomali sinomkhawulo.

I-asymmetry yolwazi lobuchwepheshe: Abasebenzisi abaningi emakethe abanakho ukuqonda okwanele kwezici zobuchwepheshe zamavalvu e-Venturi namavalve ovemvane, okuholela esidingweni esikhulu samavalvu ovemvane emakethe.

Izidingo zemvelo eziphansi: Kwezinye izikhathi lapho izidingo zokulawula imvelo zingekho phezulu, amavalvu ovemvane afaneleka ngokugcwele ngakho asetshenziswa kakhulu. .

Ukufakwa kalula nokugcinwa: I-valve uvemvane inesakhiwo esilula, indawo encane yokufaka, isisindo esilula, nokugcinwa kalula, okufanele ngezikhathi ezidinga ukufakwa nokugcinwa okusheshayo. .

Yiziphi izinhlobo ze-Venturi Tube Butterfly Valves

Izinhlobo zeI-Venturi Tube Butterfly Valvesikakhulukazi zihlanganisa okulandelayo:

I-valve ye-butterfly yohlobo lwe-wafer:

Eklanyweni yohlobo lwe-valve uvemvane, ipuleti levemvane lifakwa eceleni kobubanzi bepayipi ukuqinisekisa ukuthi ivalvu ihlezi isesimweni esivuleke ngokugcwele. Lo mklamo unesakhiwo esilula, izinyawo ezincane, nesisindo esincane. I-valve yevemvane yohlobo lwe-wafer ihlinzeka ngezindlela ezimbili zokuvala: ukuvala okunwebekayo kanye nokuvala uphawu kwensimbi, ezifanele izimo ezihlukahlukene zokusetshenziswa. .

I-valve ye-butterfly yohlobo lwe-Flange:

Ivalve yovemvane yohlobo lwe-flange isebenzisa idizayini yepuleti eqondile, futhi isiqu se-valve siyisakhiwo sensimbi esibalulekile ukuze kuqinisekiswe ukuzinza kwevalvu. Indandatho yayo yokuvala yamukela indandatho yokuvala eyinhlanganisela yepuleti le-graphite eliguquguqukayo nepuleti lensimbi engagqwali, elifanele imidiya ehlukahlukene. Amavalvu ovemvane ohlobo lwe-Flange afaneleka ngezikhathi ezidinga ukuzinza okuphezulu nomthelela wokuvala . .

I-valve butterfly eshiselwe:

I-valve butterfly eshiselwe ivalve yevemvane engavaliwe elungele izinto zokwakha, i-metallurgy, izimayini namandla. Ifanele amapayipi anezinga lokushisa eliphakathi nendawo elingeqi ku-300 ° C kanye nokucindezela okulinganiselwe okungu-0.1MPa, futhi ingafinyelela ukuxhumana okuphakathi, ukuvulwa nokuvala noma ukulawulwa. .

I-valve butterfly enemicu:

Umzimba we-valve we-valve uvemvane onentambo uhlinzekwa ngemicu yangaphakathi noma yangaphandle, elungele ukuxhunywa nemicu yamapayipi. Le valve uvemvane isetshenziswa kabanzi ezintweni zokwakha, i-metallurgy, izimayini namandla. .

I-clamp butterfly valve:

I-valve uvemvane i-clamp inesinciphisi ekwakhiweni kokuthuthukisa ukusebenza kahle futhi ifanele amapayipi anobubanzi obukhulu. Umzimba we-valve wayo wenziwe ngensimbi ye-carbon ecwengekile, futhi indandatho yokuvala yenziwe ngendandatho yensimbi, elungele izikhathi ezidinga ukusebenza njalo noma ukucindezela okuphezulu. .

Lezi zinhlobo ezahlukeneI-Venturi tube butterfly valvesbabe nezici zabo kanye nezimo ezisebenzayo. Abasebenzisi bangakhetha uhlobo olufanele ngokwezidingo ezithile.
