Tharollo e Khabane
Li-valve tsa butterfly tse sebelisoang maemong a fapaneng a ts'ebetso li tla fihlela litlhoko tse latelang: sebopeho se matla le se tšepahalang, se theko e phahameng haholo, le kopo ea bareki.Re ikemiselitse ho qapa le ho nts'etsapele lihlahisoa tse ncha tse shebaneng le bareki, tse bonts'ang boleng bo holimo kahong ea boenjiniere le ho kenya kapa tlhahisong le ts'ebetsong.
Mefuta ea rona ea li-valve tsa serurubele e ka sebelisoa metsing a nooang, metsi a sa noeng, likhoerekhoere, khase, likaroloana, ho emisoa, joalo-joalo.
Ka hona, li ka sebelisoa ho fana ka metsi a litoropong le ho tsamaisa metsi, boenjiniere ba hydraulic, khase, khase ea tlhaho, indasteri ea lik'hemik'hale, peterole, matla a motlakase, metallurgy le liindasteri tse ling, 'me li rorisitsoe haholo ke bareki.
Re kenya tšebetsong moralo oa li-valve ka thata le litekanyetso tsa tlhahiso e le motheo oa moralo oa sehlahisoa se secha.Ka boqapi ba theknoloji, ho na le tiisetso e phahameng ea polokeho, katleho moruong le bophelo ba litšebeletso, hape e tlisa meputso e phahameng ho bareki.
Lintlha tse latelang tsa 6 li bontša hore CVG Valve e fihlile boleng bo phahameng ka ho fetisisa.
1. Fluid Dynamics - Moralo oa Disc o Nolofalitsoeng
Liphaephe tsa phetisetso ea metsi tlas'a maemo a fapaneng a ts'ebetso hangata li na le khatello e phahameng haholo e sa tsitsang, e hlokang hore valve ea serurubele e mamelle matla a senyang a bakoang ke ho fetoha ha khatello ho netefatsa ts'ebetso e sireletsehileng.Hangata ho na le litharollo tse peli: e 'ngoe ke ho sebelisa disc e matla, e ka hanyetsang likhatello tsena tse sa tsitsang ha valve e buloa le ho koaloa;e 'ngoe ke ho theha sebopeho sa "valve disc" le "contour" ea ka hare ea 'mele oa valve ho lumellana le litšobotsi tsa phallo ea mokelikeli, e le hore tahlehelo ea khatello e fokotsehe ha valve e bulehile ka ho feletseng ho netefatsa hore e sebetsa hantle le ho boloka matla. ts'ebetso.
Moralo oa Disc o otlolohileng
Re sebelisa theknoloji e tsoetseng pele ka ho fetisisa e sebelisoang ke k'homphieutha ho rala disc ea valve hore e be sebopeho sa wavy.Moqapi oa wavy o fana ka botsitso bo molemo ho mokelikeli o fetang, o fokotsa tahlehelo ea khatello mme o lumella ho behoa ha cavitation ka katleho.
Tšireletseho e Tiisitsoe ka Maemo a Mathata a ho sebetsa
Litlhoko tse matla haholoanyane li hlokoa bakeng sa boholo bo boholo kapa li-valve tsa khatello e phahameng maemong a feteletseng a ho sebetsa.E le ho rarolla bothata bona, re ntlafalitse moralo oa mantlha oa li-disk tse peli tse ipapisitseng le topology.Moralo ona oa mochine oa skeleton o nolofalletsa disc hore e be le matla a phahameng, a ka sebelisoang bakeng sa khatello e phahameng e hlokahalang le maemo a maholo a bophara.Ka lehlakoreng le leng, phallo ea phallo ea karolo ea sefapano e ka ntlafatsoa ho fokotsa coefficient ea ho hanyetsa phallo.
2. Precision - Good Fit of Precision Parts
Setsi sena se na le lisebelisoa tse ngata tsa CNC, litsi tsa machining, litsi tsa ts'ebetso ea gantry le lisebelisoa tse ling tse bohlale.Ha e ntlafatse haholo tlhahiso ea basebetsi le ho fokotsa litšenyehelo tsa tlhahiso, empa hape e na le litšobotsi tse latelang:
▪ Boemo bo phahameng ba ho pheta-pheta le boleng ba sehlahisoa se tsitsitseng, tekanyo e tlaase haholo e sa lokelang.
▪ Lihlahisoa li nepahetse haholo.Mefuta eohle ea tataiso e nepahetseng e phahameng, ho beha maemo, ho fepa, ho lokisa, ho lemoha, lisebelisoa tsa pono kapa likarolo li amoheloa mochine, o ka netefatsang ho nepahala ho phahameng ha lihlahisoa le tlhahiso ea lihlahisoa.
Likarolo tse nepahetseng tse phahameng li netefatsa hore li-valve tse kopaneng li na le ts'ebetso e ntle ea ho tiisa.E ntlafatsa haholo boleng ba sehlahisoa le ponahalo.
3. Matla - Phetisetso ea Matla a Haholo
Li-valve disc le stem li sebelisa khokahano e tšepahalang le e tiileng ea polygonal, e ke keng ea sisinyeha nakong ea ts'ebetso mme e ka fetisa matla a mangata.
E le hore torque ea ho khanna e fetisetsoe ka mokhoa o ts'eptjoang ho disc ea valve, ho amana pakeng tsa valve ea valve le stem ea valve ho hloka ho tšepahala le ho tiea.Re amohetse mokhoa ona o ka tšeptjoang oa khokahanyo ea li-valve tsa polygonal ho netefatsa phetisetso e tšepahalang ea torque le ka nako e ts'oanang ho netefatsa hore ha ho na letho pakeng tsa disc ea valve le stem.Ka lebaka la khokahanyo ea li-valve tsa polygonal ntle le keyway, e ka hlahisa torque e fetang 20% ho feta shaft ea keyed ea bophara bo lekanang, e ntlafatsang haholo matla a eona a phetisetso ea torque.
Ka nako e ts'oanang, sebopeho sena ha se hloke ho phunya holim'a diski ea valve, ho qoba ho kopana pakeng tsa sekhahla sa valve le bohareng, 'me se ka lelefatsa bophelo ba tšebeletso.
4. Tšireletso ea Bokaholimo - E Loketse Maemo a sa Tšoaneng a Mosebetsi
Theknoloji e tsoetseng pele ea ho fafatsa li-valve e thusa valve hore e sireletsehe hantle maemong afe kapa afe a ho sebetsa.
Sebaka sa valve se tšoaroa ka mokhoa oa ho phatloha ha lehlabathe, ebe ka ho fafatsa ka polasetiki kapa mokhoa oa ho penta ho latela boholo ba valve.
Seaparo se tloaelehileng sa Epoxy
Ho roala ha epoxy resin ke thepa e tloaelehileng ea ho thibela ho bola.Ho na le melao e thata bakeng sa botenya le mocheso ts'ebetsong ea phekolo.Mocheso o tlameha ho fihla ho 210 ℃, 'me botenya ha bo ka tlaase ho 250 microns kapa esita le 500 microns.Ho roala ha ho na kotsi 'meleng oa motho' me ho bolokehile ka ho feletseng bakeng sa metsi a nooang.
Ho roala ho khethehileng bakeng sa Tšireletso ea Corrosion
Ho roala ho khethehileng ho fana ka tšireletso e ka tšeptjoang bakeng sa valve, haholo-holo bakeng sa maemo a mang a thata a ho sebetsa, a kang acid kapa alkali media, metsi a nang le sediment, tsamaiso ea pholileng, tsamaiso ea matla a metsi, metsi a leoatle, metsi a letsoai le metsi a litšila a indasteri.
5. Polokeho - Boleng bo Phahameng le ho Bonolo ho Boloka
Litiiso le li-bearings tsa CVG Butterfly Valve li ka sebelisoa ka mokhoa o sireletsehileng ka lilemo tse ngata 'me ho bonolo ho li hlokomela.CVG Valve e thehile maemo a macha tšimong ena.
Plasma arc welding e sebelisetsoa ho futhumatsa le ho hokahanya thepa e ka holimo le thepa ea motheo ho tšepe.
Tšireletso e Feletseng - Lesale la Setulo
Li-valve tsa serurubele tsa CVG li sebelisa selikalikoe sa setulo se cheselitsoeng se koahetsoeng ka XXX kahare.Ts'ebetsong ena, li-alloys tse khethehileng li tšeloa ho lisebelisoa tsa motheo tsa 'mele oa valve.Ts'ebetso ena e fana ka khanyetso e phahameng haholo ho corrosion ea likoti le ho senya.E boetse e hanyetsana le li-inorganic acid, mecha ea litaba ea alkaline, metsi a leoatle le metsi a letsoai, esita le mecha ea mocheso e phahameng ea mocheso.Sebopeho sena se lumella lesale la tiiso ea rabara le setulo sa valve hore se tsamaisane hantle.
Tiiso e ka Sehloohong bakeng sa Tlhokomelo e Bonolo
Lesale la ho tiisa la valve ea serurubele sa CVG le hatelloa ke poleiti e fetolang ea khatello ebe e tlamelloa ho disc ea valve.Sebopeho sena se ka fetoloa le ho nkeloa sebaka ke reng ea ho tiisa ka nako leha e le efe.Lesale la ho tiisa le ka etsoa ka fluororubber (FKM), polyurethane kapa lisebelisoa tse ling.
6. Litlhaloso - Sehlahisoa se le seng se Koahetse Litlhaloso Tsohle
Joaloka li-valve tse sebelisoang haholo, li-valve tsa serurubele li ka sebelisoa lits'ebetsong tse ngata.CVG butterfly valve ke khetho e ntle ka ho fetisisa: litlhaloso tse feletseng, mefuta e mengata ea kopo, 'me e ka sebelisoa ka hare, marang-rang a liphaephe le maemo a mang a ho sebetsa.
Bophahamo bo ikhethileng ba valve ea serurubele sa CVG bo tloha ho DN50 ho ea ho DN4500, 'me khatello ea lebitso e tloha PN2.5 ho ea PN40.Letoto lena la lihlahisoa li hlahisoa ka mohala o tšoanang oa kopano.
Bakeng sa lihlahisoa tsohle, ho na le lintlha tse peli tse latelang:
▪ Likoti tse ling tsa flange bakeng sa ho phahamisa le ho tsamaisa valve habonolo.
▪ Tšehetso ea karolo e le 'ngoe e etsa hore ho behoa ha valve ho tsitsitse haholoanyane.
