I-Venturi Tube Butterfly Valve: Ukulawulwa kokuHamba okuFanelekileyo kunye nosetyenziso lweCarb

Yintoni ityhubhu yeVenturi

Ityhubhu yeVenturi, ekwaziwa njengetyhubhu yeVenturi okanye iVenturi nozzle, sisixhobo esisetyenziselwa ukulinganisa umahluko woxinzelelo lolwelo. Isebenzisa umgaqo weBernoulli kunye ne-Cauchy equation kwi-fluid dynamics eqhubekayo ukuvelisa ukuhluka koxinzelelo xa i-fluid idlula kwi-contraction eyenzelwe ngokukodwa kunye nemilo yokwandisa kumbhobho, kwaye iguqule le ntlukwano yoxinzelelo kwixabiso lokulinganisa izinga lokuhamba kunye nesantya sokuhamba.

Umgaqo wokusebenza weVenturi Tube

I-tube ye-Venturi iqukethe umbhobho omde we-conical kunye necandelo le-contraction phakathi kombhobho. I-fluid inyuka kwisantya kwaye iyancipha kwixinzelelo xa idlula kweli candelo lokunciphisa; emva koko ngokuthe ngcembe ibuyela kwimo yayo yokuqala kwicandelo lokwandiswa. Ngokulinganisa ukuhluka koxinzelelo phakathi kwecandelo lokuqhawula kunye necandelo lokwandiswa, izinga lokuhamba kunye nesantya sokuhamba kwamanzi kunokufumaneka.

Iintlobo zeevalvu kwi-Venturi Tube

Iindidi zeevalvu kwimibhobho yeVenturi ikakhulu zibandakanya oku kulandelayo:

Ivalve yomthamo womoya rhoqo:

Umsebenzi wale valve kukugcina ukuphuma komoya okuzinzileyo.

Ivalve yeBistable:

Inokutshintsha ukuze ibonelele ngamazinga amabini ahlukeneyo okuhamba komoya, oko kukuthi, ubuninzi bezinga lokuqukuqela kunye nesantya esisezantsi sokuhamba.

...

Ivalve yomthamo womoya oguquguqukayo:

Inokuphendula okuphezulu, inokuphendula kwimiyalelo ngaphakathi kwe-1 yesibini, kwaye ifezekise ukulawulwa kwe-loop evaliweyo ngokusebenzisa izibonakaliso zempendulo, ngaloo ndlela ilungisa ngokuchanekileyo ukuhamba komoya.
Umgaqo wokusebenza kwezi valves usekelwe kwimpembelelo ye-Venturi, oko kukuthi, xa umoya uhamba nge-valve, indawo yayo yokuvula iya kulungelelanisa ngokuzenzekelayo ngokwenguqu yesantya sokuhamba, ukuze kufezekiswe ulawulo olucacileyo lokuhamba komoya. Isiphumo se-Venturi sibhekisela kwinto yokuba emva kokuba umoya udlula kumbhobho oyancipha ngokuthe ngcembe, izinga lokuhamba liya kwanda kakhulu, kwaye uxinzelelo luya kuncipha, ngaloo ndlela lufezekise ulawulo oluchanekileyo lokuhamba komoya.

Kutheni ukhetha ivalve yebhabhathane njengeVenturi Tube Valve

Izizathu zokukhetha ivalve yebhabhathane njengeVenturi Tube Valve ikakhulu ibandakanya oku kulandelayo:

Ukusebenza kweendleko: Ixabiso levalve yebhabhathane liphantsi ngokwentelekiso, ngokuqhelekileyo malunga nekota enye yevalve yeVenturi. Oku kuqwalaselwa okubalulekileyo xa uhlahlo lwabiwo-mali lunqongophele.

I-asymmetry yolwazi lobuchwephesha: Abasebenzisi abaninzi kwimarike abanakho ukuqonda okwaneleyo kweempawu zobugcisa zeVenturi iivalvu kunye neevalvu zebhabhathane, okukhokelela kwimfuno enkulu yeevalvu zebhabhathane kwimarike.

Iimfuno ezisezantsi zokusingqongileyo: Kwezinye iimeko apho iimfuno zolawulo lokusingqongileyo zingekho phezulu, iivalvu zamabhabhathane zinobuchule obupheleleyo ngoko ke zisetyenziswa ngokubanzi. ...

Ufakelo olulula kunye nokugcinwa: Ivalve yebhabhathane inesakhiwo esilula, indawo encinci yokufakela, ubunzima obulula, kunye nokugcinwa lula, okufanelekile kwiimeko ezifuna ukufakwa kunye nokugcinwa ngokukhawuleza. ...

Zeziphi iintlobo zeVenturi Tube Butterfly Valves

Iintlobo zeIivalvu zebhabhathane zeVenturi Tubeikakhulu ibandakanya oku kulandelayo:

Ivalve yebhabhathane yohlobo lweWafer:

Kuyilo lwevalve yohlobo lwebhabhathane, ipleyiti yebhabhathane ifakwe ecaleni kwedayamitha yombhobho ukuqinisekisa ukuba ivalve isoloko ikwimo evuleke ngokupheleleyo. Olu luyilo lunesakhiwo esilula, unyawo oluncinci, kunye nobunzima obulula. Ivalve yebhabhathane yohlobo lwe-wafer ibonelela ngeendlela ezimbini zokutywina: ukutywinwa kwe-elastiki kunye nokutywinwa kwentsimbi, ezilungele iimeko ezahlukeneyo zesicelo. ...

Ivalve yohlobo lwebhabhathane:

Ivalve yohlobo lwebhabhathane ithatha uyilo oluthe nkqo kwipleyiti, kwaye isiqu sevalve sisakhiwo sentsimbi esidityanisiweyo sokuqinisekisa uzinzo lwevalve. Umsesane wayo wokutywina wamkela umsesane wokutywina odibeneyo weplate yegraphite eguquguqukayo kunye nepleyiti yensimbi engenasici, efanelekileyo kwimidiya eyahlukeneyo. Iivalve zebhabhathane zohlobo lweflange zifanelekile kwizihlandlo ezifuna uzinzo oluphezulu kunye nesiphumo sokutywinwa. i

Ivalve yebhabhathane edityanisiweyo:

Ivalve yebhabhathane eWelded yivalve yebhabhathane engatywinwanga elungele izixhobo zokwakha, isinyithi, imigodi kunye namandla.

Ivalve yebhabhathane enemisonto:

Umzimba wevalve yevalve yebhabhathane enemisonto inikwe ngemisonto yangaphakathi okanye yangaphandle, elungele ukudityaniswa nemisonto yombhobho. Le valve yebhabhathane isetyenziswa kakhulu kwizinto zokwakha, isinyithi, imigodi kunye namandla. ...

Ivalve yebhabhathane ebambayo:

Ivalve yebhabhathane ebambayo inesinciphisi kuyilo lokuphucula ukusebenza kwaye ifanelekile kwimibhobho yobubanzi obukhulu. Umzimba wayo wevalve wenziwe ngentsimbi yekhabhoni esulungekileyo, kwaye umsesane wokutywina wenziwa ngomsesane wentsimbi, olungele iimeko ezifuna ukusebenza rhoqo okanye uxinzelelo oluphezulu. ...

Ezi ntlobo zahlukeneyo zeVenturi tube butterfly valvesbaneempawu zabo kunye neemeko ezifanelekileyo. Abasebenzisi banokukhetha uhlobo olufanelekileyo ngokweemfuno ezithile.
