Velve ea Serurubele ea Venturi Tube: Taolo ea Phallo e Botle ka ho Fetisisa le Litšebeliso tsa Carb

Phaephe ea Venturi ke eng

Tube ea Venturi, e tsejoang hape e le tube ea Venturi kapa nozzle ea Venturi, ke sesebelisoa se sebelisetsoang ho lekanya phapang ea khatello ea mokelikeli. E sebelisa molao-motheo oa Bernoulli le equation ea Cauchy ho dynamics ea mokelikeli o tsoelang pele ho hlahisa phapang ea khatello ha mokelikeli o feta ka har'a libopeho tse entsoeng ka ho khetheha tsa ho honyela le katoloso ka har'a phaephe, 'me e fetola phapang ena ea khatello hore e be boleng ba tekanyo ea sekhahla sa phallo le sekhahla sa phallo.

Molao-motheo oa ho sebetsa oa Venturi Tube

Phaephe ea Venturi e na le phaephe e telele e kobehileng e nang le karolo ea ho honyela bohareng ba phaephe. ​​Mokelikeli o eketseha ka lebelo 'me o fokotseha khatellong ha o feta karolong ena ea ho honyela; ebe butle-butle o khutlela boemong ba oona ba pele karolong ea katoloso. Ka ho lekanya phapang ea khatello pakeng tsa karolo ea ho honyela le karolo ea katoloso, sekhahla sa phallo le sekhahla sa phallo ea mokelikeli li ka fumanoa.

Mefuta ea li-valve ho Venturi Tube

Mefuta ea li-valve liphaepheng tsa Venturi e kenyelletsa tse latelang haholo-holo:

Valve ea bophahamo ba moea e sa khaotseng:

Mosebetsi oa valve ena ke ho boloka phallo ea moea e tsitsitseng.

Valve e ka tšeptjoang:

E ka fetoha ho fana ka ditekanyo tse pedi tse fapaneng tsa phallo ya moya, e leng sekgahla se phahameng ka ho fetisisa sa phallo le sekgahla se tlase sa phallo.

‌

Valve ea bophahamo ba moea e fetohang:

E na le karabelo e phahameng, e ka arabela litaelo ka motsotsoana o le mong, mme ea fihlella taolo e koetsoeng ka matšoao a karabelo ea phallo, ka hona e lokisa phallo ea moea ka nepo.
Molao-motheo oa ts'ebetso oa li-valve tsena o ipapisitse le phello ea Venturi, ke hore, ha moea o phalla ka har'a valve, sebaka sa eona sa ho buleha se tla ikamahanya le maemo ho latela phetoho ea sekhahla sa phallo, e le ho fihlella taolo e qaqileng ea phallo ea moea. Phello ea Venturi e bolela 'nete ea hore ka mor'a hore moea o fete ka har'a phaephe e ntseng e fokotseha butle-butle, sekhahla sa phallo se tla eketseha haholo, 'me khatello e tla fokotseha, ka hona ho fihlella taolo e nepahetseng ea phallo ea moea.

Hobaneng u khetha valve ea serurubele joalo ka Venturi Tube Valve

Mabaka a ho khetha valve ea serurubele e le Venturi Tube Valve a kenyelletsa haholo-holo tse latelang:

Katleho ea litšenyehelo: Litšenyehelo tsa valve ea serurubele li tlase haholo, hangata hoo e ka bang kotara ea valve ea Venturi. Ena ke taba ea bohlokoa ha tekanyetso e lekanyelitsoe.

Asymmetry ea tlhahisoleseling ea tekheniki: Basebelisi ba bangata 'marakeng ha ba na kutloisiso e lekaneng ea litšobotsi tsa tekheniki tsa li-valve tsa Venturi le li-valve tsa lirurubele, e leng se fellang ka tlhoko e kholo ea li-valve tsa lirurubele 'marakeng.

Litlhoko tse tlase tsa tikoloho: Maemong a mang moo ditlhoko tsa taolo ya tikoloho di seng hodimo, di-valve tsa dirurubele di na le bokgoni bo felletseng mme ka hona di sebediswa haholo.

Ho kenya le ho hlokomela habonolo: Valve ea serurubele e na le sebopeho se bonolo, sebaka se senyenyane sa ho kenya, boima bo bobebe, le tlhokomelo e bonolo, e loketseng liketsahalo tse hlokang ho kenngoa le ho hlokomeloa kapele.

Mefuta ea Li-valve tsa Venturi Tube Butterfly ke efe?

Wafer mofuta wa serurubele belofo:

Moralong oa valve ea serurubele ea mofuta oa wafer, poleiti ea serurubele e kentsoe ka bophara ba phaephe ho netefatsa hore valve e lula e butsoe ka botlalo. Moralo ona o na le sebopeho se bonolo, sebaka se senyenyane sa maoto, le boima bo bobebe. Valve ea serurubele ea mofuta oa wafer e fana ka mekhoa e 'meli ea ho koala: ho tiisa ka mokhoa o tenyetsehang le ho tiisa ka tšepe, e loketseng maemo a fapaneng a ts'ebeliso ‌.

Flange mofuta oa serurubele valve:

Valve ea serurubele ea mofuta oa flange e sebelisa moralo oa poleiti e otlolohileng, 'me kutu ea valve ke sebopeho sa tšepe sa bohlokoa ho netefatsa botsitso ba valve. Lesale la eona la ho tiisa le sebelisa lesale la ho tiisa le kopaneng la poleiti e tenyetsehang ea graphite le poleiti ea tšepe e sa hloekang, e loketseng mecha e fapaneng ea phatlalatso. Li-valve tsa serurubele tsa mofuta oa flange li loketse liketsahalo tse hlokang botsitso bo phahameng le phello ea ho tiisa ‌. ‌ ‌

Valve ea serurubele e bōpehileng joaloka welded:

Valve ea serurubele e welded ke valve ea serurubele e sa koaloang e loketseng thepa ea kaho, tšepe, merafo le motlakase. E loketse liphaephe tse nang le mocheso o mahareng o sa feteng 300°C le khatello e tloaelehileng ea 0.1MPa, 'me e ka fihlella khokahano e mahareng, ho buleha le ho koala kapa taolo.

Valve ea serurubele e nang le khoele:

'Mele oa valve oa valve ea serurubele e nang le khoele o fanoe ka likhoele tsa kahare kapa tsa kantle, tse loketseng ho hokahanngoa le likhoele tsa liphaephe. ​​Valve ena ea serurubele e sebelisoa haholo thepa ea kaho, tšepe, merafo le motlakase.

Valve ea serurubele e khomarelang:
