I-Venturi Tube Butterfly Valve: Ulawulo lokuhamba kwamanzi olusebenza kakuhle kunye nezicelo zeCarb

Yintoni ityhubhu yeVenturi

Ityhubhu yeVenturi, eyaziwa ngokuba yityhubhu yeVenturi okanye i-Venturi nozzle, sisixhobo esisetyenziselwa ukulinganisa umahluko woxinzelelo lolwelo. Isebenzisa umgaqo weBernoulli kunye ne-Cauchy equation kwi-continuous fluid dynamics ukuvelisa umahluko woxinzelelo xa ulwelo ludlula kwiimilo ezicwangcisiweyo ngokukodwa kunye nokwandiswa kwipayipi, kwaye iguqula lo mahluko woxinzelelo ube lixabiso lokulinganisa izinga lokuhamba kunye nezinga lokuhamba.

Umgaqo wokusebenza weVenturi Tube

Ityhubhu yeVenturi inombhobho omde ojiyileyo onecandelo lokucutha embindini wombhobho. Ulwelo luyanda ngesantya kwaye lunciphe uxinzelelo xa ludlula kweli candelo lokucutha; emva koko lubuyela kancinci kancinci kwimeko yalo yokuqala kwicandelo lokukhutha. Ngokulinganisa umahluko woxinzelelo phakathi kwecandelo lokucutha kunye necandelo lokukhutha, izinga lokuhamba kunye nezinga lokuhamba kolwelo linokufunyanwa.

Iintlobo zeevalvu kwiVenturi Tube

Iindidi zeevalvu kwiipayipi zeVenturi ziquka ezi zilandelayo:

Ivalvu yomthamo womoya oqhubekayo:

Umsebenzi wale valve kukugcina umoya uphuma ngendlela ezinzileyo.

Ivalvu ebhityileyo:

Ingatshintsha ukuze inike amazinga amabini ahlukeneyo okuhamba komoya, oko kukuthi izinga eliphezulu lokuhamba komoya kunye nezinga elincinci lokuhamba komoya.

‌

Ivalvu yomoya eguquguqukayo:

Iphendula ngokukhawuleza, ingaphendula kwimiyalelo kwisithuba semizuzwana e-1, kwaye ifikelele kulawulo oluvaliweyo ngemiqondiso yempendulo yokuhamba, ngaloo ndlela ilungisa ngokuchanekileyo ukuhamba komoya.
Umgaqo wokusebenza kwezi valves usekelwe kwisiphumo seVenturi, oko kukuthi, xa umoya udlula kwivalvu, indawo yawo yokuvula iya kulungelelanisa ngokuzenzekelayo ngokwenguqu yesantya sokuhamba komoya, ukuze kufezekiswe ulawulo oluneenkcukacha lokuhamba komoya. Isiphumo seVenturi sibhekisa kwinto yokuba emva kokuba umoya udlule kumbhobho oncipha kancinci kancinci, izinga lokuhamba komoya liya kwanda kakhulu, kwaye uxinzelelo luya kuncipha, ngaloo ndlela kufezekiswe ulawulo oluchanekileyo lokuhamba komoya.

Kutheni ukhetha ivalvu yebhabhathane njengeVenturi Tube Valve

Izizathu zokukhetha ivalvu yebhabhathane njengeVenturi Tube Valve ziquka oku kulandelayo:

Ukusebenza kakuhle kweendleko: Ixabiso levalvu yebhabhathane liphantsi kakhulu, lidla ngokuba malunga nekota yexabiso levalvu yeVenturi. Oku kubalulekile xa uhlahlo lwabiwo-mali lulinganiselwe.

Ukungalingani kolwazi lobuchwepheshaAbasebenzisi abaninzi kwimarike abanalo ulwazi olwaneleyo ngeempawu zobugcisa zeevalvu zeVenturi kunye neevalvu zebhabhathane, nto leyo ebangela imfuno enkulu yeevalvu zebhabhathane kwimarike.

Iimfuno eziphantsi zokusingqongileyoKwezinye iimeko apho iimfuno zolawulo lokusingqongileyo zingekho phezulu, iivalvu zebhabhathane zisebenza kakuhle kwaye ngenxa yoko zisetyenziswa kakhulu.

Ukufakela nokugcinwa lulaIvalvu yebhabhathane inesakhiwo esilula, indawo encinci yokufakela, ubunzima obulula, kunye nokugcinwa okulula, okufanelekileyo kwiimeko ezifuna ukufakwa nokugcinwa ngokukhawuleza.

Ziziphi iintlobo zeeVenturi Tube Butterfly Valves

Iintlobo zeIivalvu zeVenturi Tube Butterflyikakhulu ziquka oku kulandelayo:

Ivalvu yebhabhathane yohlobo lwesonka esisicaba:

Kuyilo lwevalvu yebhabhathane yohlobo lwe-wafer, ipleyiti yebhabhathane ifakwe kububanzi bombhobho ukuqinisekisa ukuba ivalvu ihlala ikwimeko evulekileyo ngokupheleleyo. Olu yilo lunesakhiwo esilula, indawo encinci, kunye nobunzima obulula. Ivalvu yebhabhathane yohlobo lwe-wafer inika iindlela ezimbini zokutywina: ukutywina okuthambileyo kunye nokutywina ngesinyithi, ezifanelekileyo kwiimeko ezahlukeneyo zokusetyenziswa ‌.

Ivalvu yebhabhathane yohlobo lweFlange:

Ivalvu yebhabhathane yohlobo lweflange isebenzisa uyilo lwepleyiti ethe nkqo, kwaye isiqu sevalvu sisakhiwo sesinyithi esidibeneyo ukuqinisekisa uzinzo lwevalvu. Iring yayo yokutywina isebenzisa iringi yokutywina edibeneyo yepleyiti yegrafiti eguquguqukayo kunye nepleyiti yentsimbi engagqwaliyo, efanelekileyo kwiindidi ezahlukeneyo zemidiya. Iivalvu zebhabhathane zohlobo lweflange zifanelekile kwiimeko ezifuna uzinzo oluphezulu kunye nesiphumo sokutywina ‌. ‌ ‌

Ivalvu yebhabhathane edibeneyo:
