Ukusebenza okuphezulu kweValve yebhabhathane
✧ Inkcazo
Ivalve yebhabhathane esebenza kakhulu luhlobo lwevalve eyenzelwe izicelo ezifuna ukutywinwa okuthembekileyo, amandla oxinzelelo oluphezulu, kunye nokuvalwa okuqinileyo.Ezi zivalo zisetyenziswa ngokuqhelekileyo kumashishini afana neoli kunye negesi, ukusetyenzwa kweekhemikhali, ukuveliswa kwamandla, kunye nonyango lwamanzi, phakathi kwabanye.Zibonakaliswa ngokukwazi ukubonelela ngokulawula ukuhamba kakuhle kunye nokumelana neemeko zokusebenza ezinzima.Ezinye iimpawu eziphambili zeevalve ze-butterfly ezisebenza ngokuphezulu ziquka: Ukuvalwa okuCiniweyo: Ezi zivalo zenzelwe ukunciphisa ukuvuza kunye nokubonelela ngesitywina esithembekileyo nakwi-high-pressure. okanye iindawo ezinobushushu obuphezulu.Ulwakhiwo oluqinileyo: Iivalve zebhabhathane ezisebenza ngokuphezulu zihlala zakhiwe ngezinto ezihlala ixesha elide, njengensimbi engenasici okanye i-alloys exotic, ukumelana ne-corrosive or abrasive media.I-Low Torque Operation: Iivalve ezininzi zebhabhathane ezisebenza ngokuphezulu zenzelwe ukuncipha. ukusebenza kwe-torque, okuvumela ukusebenza ngokufanelekileyo kunye nokunciphisa ukunxiba kwiingxenye zevalve. Uyilo oluKhuselekileyo loMlilo: Ezinye iivalve zebhabhathane ezisebenza ngokuphezulu zenzelwe ukuhlangabezana nemigangatho yokhuseleko lomlilo, zibonelela ngokhuseleko olongezelelweyo kwimeko yomlilo. : Ezi zivalo zifanelekile kwizicelo ezifuna i-high-pressure handling capabilities.Xa ukhetha i-valve ye-butterfly ephezulu, kubalulekile ukuqwalasela izinto ezifana nesicelo esithile, iimeko zokusebenza, ukuhambelana kwezinto, imigangatho yoshishino kunye nokuqwalaselwa kokusingqongileyo.Ubungakanani obufanelekileyo kunye nokukhetha kubalulekile ukuqinisekisa ukuba i-valve ihlangabezana neemfuno zokusebenza kwesicelo esicetywayo.
✧ Iimpawu ze-High Performance Butterfly Valve
Iivalvu zeBhavane eziSebenza ngokuPhezulu zinezihlalo ezidityanisiweyo zepolymer ezinobude obungasikelwanga mda bokuphila kunye nokumelana nemichiza ephezulu kakhulu - zimbalwa iikhemikhali ezaziwa ngokuchaphazela iipholima ezisekelwe kwi-fluorocarbon, zenza ezi mveliso zibe nomtsalane kwiinkqubo zevalvu yeshishini.Umgangatho wayo udlula irabha okanye ezinye iipolymers ze-fluorocarbon ngokubhekiselele kuxinzelelo, ubushushu kunye nokumelana nokunxiba.
Uyilo olupheleleyo lwevalve
Isiqu se-High Performance Butterfly Valve singekho embindini kwiinqwelomoya ezimbini.I-offset yokuqala ivela kumgca ophakathi wevalve, kwaye i-offset yesibini ivela kumgca ophakathi wombhobho.Oku kubangela ukuba i-disc ikhuphe ngokupheleleyo kwi-disc kwiidigri ezimbalwa zokusebenza kude nesihlalo.Jonga unikezelo olungezantsi:
Uyilo lwesihlalo
Ngokubhekiselele kwisihlalo, njengoko kuchaziwe ngaphambili, i-valve ene-rubber lined ivalwe ngokucinezela kwi-sleeve yerubha.Ukusebenza okuphezulu kweButterfly Valve G uyilo lwesihlalo.Lo mzobo ungezantsi uchaza indlela izihlalo ezichaphazeleka ngayo kwiimeko ezi-3:
Emva kwendibano: xa idityaniswe phantsi koxinzelelo
Xa idityaniswe phantsi koxinzelelo, isihlalo siqhutywa yipleyiti yebhabhathane.Oku kuvumela ukutywinwa kweqamza ukusuka kwinqanaba levacuum ngeqondo loxinzelelo oluphezulu lwevalvu.
Uxinzelelo lweAxial:
Iprofayile yesitulo se-G yenza itywina elingqongqo njengoko ipleyiti ihamba.Uyilo lokufakela lunciphisa ukuhamba kwesihlalo ngokugqithisileyo.
Uxinzelelo kwicala lofakelo:
Uxinzelelo lujika isihlalo phambili, ukwandisa amandla okutywina.Ukufakwa kwindawo yokugoba yenzelwe ukuvumela ukujikeleza kwesihlalo.Le yeyona ndlela ithandwayo yokuxhoma.
Isihlalo seValve yeButterfly eSebenza ngokuPhezulu inomsebenzi wokukhumbula.Isihlalo sibuyela kwisimo saso sokuqala emva kokulayisha.Ukukwazi kwesihlalo ukubuyisela kuchazwa yimilinganiselo yokuguqulwa okusisigxina kwesihlalo.I-deformation esezantsi esisigxina ithetha ukuba izinto zinememori engcono - iyancipha kakhulu kwi-deformation esisigxina xa kufakwe umthwalo.Ngenxa yoko, imilinganiselo ephantsi yoguquko olusisigxina ithetha ukuphuculwa kokubuyiswa kwesihlalo kunye nexesha elide lokuphila elitywiniweyo.Oku kuthetha ukutywinwa okuphuculweyo phantsi koxinzelelo kunye nokuhamba ngebhayisikili eshushu.I-Deformation ichaphazeleka bubushushu.
Ukupakishwa kwesiqu kunye noyilo lokuzala
Inqaku lokugqibela lokuthelekisa liyitywina elithintela ukuvuza kwangaphandle kwindawo ye-stem.
Njengoko ubona ngezantsi, iivalve ezinerabha zine-stem seal elula kakhulu, engalungisekiyo.Uyilo lusebenzisa i-stem bushing ukubeka embindini weshafti kunye nee-U-cups ezi-2 zerabha ukutywina okuphakathi ukunqanda ukuvuza.
Akukho luhlengahlengiso lwenziwayo kwindawo etywiniweyo, oku kuthetha ukuba ukuba kukho ukuvuza, i-valve kufuneka ikhutshwe kumgca kwaye ilungiswe okanye ifakwe endaweni yayo.Ummandla we-shaft ophantsi awunayo inkxaso ye-stem, ngoko ke ukuba iinqununu zifudukela kwindawo ephezulu okanye engaphantsi kwe-shaft, i-torque ye-drive iphakama, ibangele ukusebenza okunzima.
IiValve zeBhavane eziSebenza ngokuPhezulu eziboniswe ngezantsi ziyilwe ngokupakishwa okuhlengahlengiswa ngokupheleleyo (i-shaft seal) ukuqinisekisa ubomi benkonzo ende kwaye akukho kuvuza kwangaphandle.Ukuba ukuvuza kwenzeka ngokuhamba kwexesha, ivalve inedlala elipakishayo elilungelelanisiweyo ngokupheleleyo.Jika iringi kuphela ngexesha de kuphele ukuvuza.
✧ Izinto eziluncedo kwiValve yeButterfly eSebenzayo
Ngethuba lokuvula kunye nokuvala i-valve yeglobhu yentsimbi ekhandiweyo, ngenxa yokuba i-friction phakathi kwe-disc kunye ne-surface yokutywina ye-valve yomzimba incinci kune-valve yesango, ayigugi.
Ukuvula okanye ukuvala i-stroke ye-valve stem ifutshane, kwaye inomsebenzi othembekileyo wokusika, kwaye ngenxa yokuba ukutshintshwa kwe-valve seat port ilingana ne-stroke ye-valve disc, ikulungele kakhulu ukulungiswa. yesantya sokuhamba.Ke ngoko, olu hlobo lwevalve lufanelekile kakhulu ukunqunyulwa okanye ukulawulwa kunye ne-throttling.
