Isisombululo esihle
Iivalvu zebhabhathane ezisetyenziswa kwiimeko ezahlukeneyo zokusebenza ziya kuhlangabezana nezi mfuno zilandelayo: ulwakhiwo oluqinileyo noluthembekileyo, olungabizi kakhulu, kunye nesicelo sabathengi.Sizibophelele ekuqulunqeni nasekuphuhliseni iimveliso ezintsha ezijoliswe kubathengi, ezibonisa umgangatho ophezulu kulwakhiwo lobunjineli kunye nofakelo okanye kwimveliso kunye nokusebenza.
Iindidi zethu zeevalvu zebhabhathane zingasetyenziswa kumanzi okusela, amanzi angaseliyo, ugutyulo, igesi, amasuntswana, ukumiswa, njl.
Ke ngoko, zinokusetyenziswa kunikezelo lwamanzi asezidolophini kunye nokuhanjiswa kwamanzi, ubunjineli be-hydraulic, igesi, igesi yendalo, ishishini lemichiza, i-petroleum, amandla ombane, isinyithi kunye namanye amashishini, kwaye ziye zadunyiswa kakhulu ngabathengi.
Siphumeza ngokungqongqo uyilo lwevalvu kunye nemigangatho yokuvelisa njengesiseko soyilo lwemveliso entsha.Ngokusebenzisa iteknoloji entsha, kukho isiqinisekiso esiphezulu sokhuseleko, ukusebenza kakuhle kwezoqoqosho kunye nobomi benkonzo, kwaye kuzisa imbuyekezo yexabiso eliphezulu kubathengi.
La manqaku ama-6 alandelayo abonisa ukuba iValve yeCVG ifikelele kumgangatho ophezulu.
1. I-Fluid Dynamics-Uyilo lweDiskhi oluLungelweyo
Imibhobho yokuhambisa amanzi phantsi kweemeko ezahlukeneyo zokusebenza ihlala inoxinzelelo oluphezulu kakhulu olungazinzanga, olufuna ukuba ivalve yebhabhathane imelane namandla atshabalalisayo abangelwa kukuguquguquka koxinzelelo ukuqinisekisa ukusebenza ngokukhuselekileyo.Ngokuqhelekileyo kukho izisombululo ezimbini: enye kukusebenzisa i-disc eqinile, enokumelana nale ngcinezelo engazinzanga xa i-valve ivuliwe kwaye ivaliwe;enye kukuyila imilo ye-valve disc kunye ne-contour yangaphakathi ye-valve yomzimba ukuze ihambelane neempawu zokuhamba kwamanzi, ukwenzela ukuba ilahleko yoxinzelelo inokuncitshiswa xa ivalve ivuleke ngokupheleleyo ukuqinisekisa ukusebenza kakuhle kunye nokonga amandla. ukusebenza.
Uyilo lweDiskhi oluHluliweyo
Sisebenzisa obona buchwepheshe buphezulu boncedo lwekhompyutha ukuyila idiskhi yevalvu ibe yimilo ejikelezayo.Uyilo lwe-wavy lunikeza ukuzinza okungcono kwi-fluid edlulayo, ukunciphisa ukulahlekelwa kwengcinezelo kunye nokuvumela ukufakwa kwe-cavitation esebenzayo.
Ukhuseleko luqinisekisiwe kwiiMeko zokuSebenza eziMandundu
Iimfuno ezinzima ngakumbi zifunwa ubungakanani obukhulu okanye iivalvu zoxinzelelo oluphezulu kwiimeko zokusebenza ezigqithisileyo.Ukuze kusonjululwe le ngxaki, siphucule uyilo lwediskhi enamaleko aphindwe kabini ngokusekwe kwitopology.Olu yilo lwenkqubo ye-skeleton yenza ukuba i-disc ibe namandla aphezulu, angasetyenziselwa uxinzelelo oluphezulu olufunekayo kunye neemeko ezinkulu zobubanzi.Ngakolunye uhlangothi, ukuhamba kokuhamba kwecandelo lomnqamlezo kunokunyuswa ukuze kuncitshiswe i-coefficient yokumelana nokuhamba.
2. Ukuchaneka - Ukulungelelaniswa okuLungileyo kweeNdawo ezichanekileyo
Iworkshop ixhotyiswe ngeelathe ezininzi ze-CNC, amaziko omatshini, amaziko okulungisa i-gantry kunye nezinye izixhobo ezikrelekrele.Ayiphuculi kakhulu imveliso yabasebenzi kunye nokunciphisa iindleko zokuvelisa, kodwa inezi mpawu zilandelayo:
▪ Iqondo eliphezulu lokuphinda-phinda kunye nobulunga bemveliso, umlinganiselo ophantsi kakhulu ongenachaphaza.
▪ Iimveliso zichaneke kakhulu.Zonke iintlobo zezikhokelo ezichanekileyo eziphezulu, ukubeka, ukutya, ukulungiswa, ukufumanisa, iinkqubo zombono okanye amacandelo amkelwe kumatshini, anokuqinisekisa ukuchaneka okuphezulu kokuhlanganiswa kwemveliso kunye nemveliso.
Amacandelo achanekileyo aqinisekisa ukuba iivalve ezidibeneyo zinomsebenzi omhle wokutywina.Iphucula kakhulu umgangatho wemveliso kunye nokubonakala.
3. Amandla - uThutho lwaMandla oluLungelelayo kakhulu
I-disc ye-valve kunye ne-stem isebenzisa uxhumano oluthembekileyo noluqinileyo lwe-polygonal, olungayi kugungqa ngexesha lokusebenza kwaye lunokuhambisa amandla amaninzi.
Ukuze i-torque yokuqhuba idluliselwe ngokuthembekileyo kwi-disc ye-valve, ukudibanisa phakathi kwe-valve disc kunye ne-valve stem kufuneka ithembeke kwaye iqine.Samkele le ndlela yokudibanisa i-valve shaft ethembekileyo ye-polygonal ukuqinisekisa ukuhanjiswa kwe-torque ethembekileyo kwaye kwangaxeshanye ukuqinisekisa ukukhutshwa kwe-zero phakathi kwe-valve disc kunye nesiqu.Ngenxa yoqhagamshelo lwe-valve ye-valve ye-polygonal ngaphandle kwe-keyway, inokukhupha ngaphezulu kwe-20% ye-torque ngaphezulu kwe-shaft yevalve ene-keyed ye-diameter efanayo, ephucula kakhulu umthamo wayo wokuhambisa i-torque.
Ngelo xesha, esi sakhiwo asifuni ukubhola kwi-disc ye-valve, igwema ukudibanisa phakathi kwe-valve stem kunye ne-medium, kwaye inokwandisa ubomi benkonzo.
4. Ukukhuselwa komphezulu-Kufanelekile kwiiMeko ezahlukeneyo zokuSebenza
Itekhnoloji yokutshiza yevalve ekwinqanaba eliphezulu yenza ukuba ivalve ikhuselwe kakuhle nakweyiphi na imeko yokusebenza.
Umphezulu wevalvu uphathwa ngenkqubo yokuqhushumba kwesanti, emva koko ngokutshizwa ngeplastiki okanye inkqubo yokupeyinta ngokobungakanani bevalvu.
Ukwaleka kweEpoxy okuMgangatho
I-epoxy resin coating yinto eqhelekileyo yonyango lwe-anti-corrosion.Kukho imigaqo engqongqo yobunzima kunye nobushushu kwinkqubo yonyango.Ubushushu kufuneka bufikelele kwi-210 ℃, kwaye ubukhulu bungekho ngaphantsi kwe-250 microns okanye i-500 microns.Ukugquma akunabungozi emzimbeni womntu kwaye kukhuselekile ngokupheleleyo kumanzi okusela.
Ukugqunywa okuKhethekileyo kuKhuseleko lokuMhlwa
Ukugquma okukhethekileyo kunika ukhuseleko oluthembekileyo lwevalve, ngakumbi kwiimeko ezithile zokusebenza ezinzima, ezifana ne-asidi okanye i-alkali media, amanzi aqulethe intlenga, inkqubo yokupholisa, iinkqubo zamanzi, amanzi olwandle, amanzi etyuwa kunye namanzi amdaka amashishini.
5. Ukhuseleko-Umgangatho ophezulu kunye nokuLula ukuLondoloza
Amatywina kunye neebheringi zeCVG Butterfly Valve zingasetyenziswa ngokukhuselekileyo iminyaka emininzi kwaye kulula ukuzigcina.IValve yeCVG iseke umgangatho omtsha kulo mmandla.
I-Plasma arc welding isetyenziselwa ukutshisa kunye nokudibanisa izinto ezingaphezulu kunye nesiseko kwintsimbi.
Ukhuseleko olupheleleyo-Isitulo seSitulo
Iivalvu zebhabhathane zeCVG zisebenzisa iringi yesitulo esidityanisiweyo ngeXXX yokwaleka ngaphakathi.Kule nkqubo, ii-alloys ezikhethekileyo zifakwe kwisiseko somzimba we-valve.Le nkqubo inika ukuxhathisa okuphezulu kakhulu kwi-corrosion ye-pitting kunye ne-crack corrosion.Ikwaxhathisa kwiiasidi ze-inorganic, imidiya yealkaline, amanzi olwandle kunye namanzi etyuwa, kunye nemithombo yeendaba zobushushu obuphezulu.Esi sakhiwo sivumela umsesane wokutywina werabha kunye nesitulo sevalve ukuba sihambelane ngokusondeleyo.
Isitywina esiPhambili soLondolozo oluLula
Iringi yokutywina yevalve yebhabhathane yeCVG icinezelwe yipleyiti yoxinzelelo lokulungelelanisa kwaye ibotshelelwe kwidiski yevalve.Esi sakhiwo sinokuhlengahlengiswa kwaye sitshintshwe ngendandatho yokutywina nanini na.Umsesane wokutywina unokwenziwa nge-fluororubber (FKM), i-polyurethane okanye ezinye izinto.
6. Iinkcukacha-Imveliso enye ibandakanya zonke iiNkcazo
Njengezona zivalo ziqhelekileyo ezisetyenziswayo, iivalve zebhabhathane zingasetyenziswa kwizicelo ezininzi.Ivalve yebhabhathane yeCVG lolona khetho lungcono: iinkcukacha ezipheleleyo, uluhlu olubanzi lwesicelo, kwaye lunokusetyenziswa ngaphakathi, inethiwekhi yombhobho kunye nezinye iimeko zokusebenza.
I-diameter ebizwa ngokuba yi-CVG butterfly valve ranges ukusuka kwi-DN50 ukuya kwi-DN4500, kunye noxinzelelo oluqhelekileyo lusuka kwi-PN2.5 ukuya kwi-PN40.Olu chungechunge lweemveliso ziveliswa kumgca wendibano efanayo.
Kuzo zonke iimveliso, kukho iinkcukacha ezimbini njengokulandelayo:
▪ Imingxuma eyongezelelweyo yeflange ukwenzela ukuphakanyiswa lula kunye nokuthuthwa kwevalve.
▪ Inkxaso yesiqwenga esinye yenza ukubekwa kwevalve kuzinze ngakumbi.
