Zithini iiValve zeButterfly ezisebenza kakuhle (iiHPBV)

1. Zithini iiValve zeButterfly ezisebenza kakuhle

Ivalvu yebhabhathane esebenza kakuhle ibhekisa kuhlobo olutsha lwemveliso yevalvu yebhabhathane ephucula ukutywinwa nokuguguleka kweevalvu zebhabhathane, yonyusa ukumelana nobushushu obuphezulu kunye nokumelana nokugqwala, kwaye iphucula ubomi benkonzo kunye nokuthembeka ngokusekelwe kwiivalvu zebhabhathane eziqhelekileyo (iivalvu zebhabhathane eziqinileyo kunye neevalvu zebhabhathane ezingaqhelekanga ezintathu) ngokuphucula isakhiwo kunye nezixhobo. Xa kuthelekiswa neevalvu zebhabhathane eziqhelekileyo, iivalvu zebhabhathane ezisebenzayo eziphezulu zinobomi obude, i-torque elula, uluhlu olubanzi loxinzelelo lokusetyenziswa, kunye nokusebenza okungcono kokuvala.

Iivalvu zebhabhathane ezisebenza kakuhle (ii-HPBV) zimele uphuhliso oluphambili loyilo lweevalvu zebhabhathane ezisemgangathweni. Zenzelwe ukuvala, ukuqina, kunye nokulawula okuphezulu kwizicelo ezibalulekileyo, zine-geometries yediski ye-offset (ephindwe kabini okanye kathathu engaqhelekanga) kwaye zisebenzisa izitywina ezihleli ngentsimbi ukuya kwisinyithi okanye eziqinileyo. Ngokungafaniyo nezinye zazo ezixineneyo,iivalvu zebhabhathane ezisebenzayo eziphezulubabalasele ekusingatheni uxinzelelo oluphezulu, amaqondo obushushu aphezulu, izixhobo ezirhabaxa, kwaye banikezela ngokuvala okuqinileyo, nto leyo ebenza babaluleke kakhulu kwiinkqubo zoshishino zanamhlanje.

1.1 Izinto ezibalulekileyo zeValve yeButterfly: Umzimba, iDiski, iStem, iSihlalo, kunye noQhagamshelo lweActuator

Izinto eziphambili zevalvu yebhabhathane zahlulwe zibe ziindidi ezintlanu eziphambili: umzimba wevalvu, idiski yebhabhathane, isiqu sevalvu, isihlalo sokutywina, kunye neendawo zoqhagamshelo lwe-actuator.

•Umzimba weValve: Umzimba wevalvu usebenza njengeqokobhe elingaphandle eliphambili, elithwala uxinzelelo lwepayipi kunye nemithwalo ephakathi ngelixa lisebenza njengesiseko sokufakelwa kwazo zonke ezinye izinto. Ifumaneka kwiindlela ze-wafer kunye ne-lug-type, eziqhele ukwenziwa ngentsimbi ephosiweyo, intsimbi yekhabhoni, okanye intsimbi engatyiwayo.

•Idiski yeValve: Idiski yebhabhathane yeyona nto ibalulekileyo ekuvuleni, ekuvaleni, nasekuqhobosheni. Uyilo lwayo olufana nediski, olufumaneka kwizakhiwo ezixineneyo okanye ezingaqhelekanga, lumisela ngokuthe ngqo ukusebenza kokutywina kunye nokumelana nokuguguleka. Kufuneka imelane nokugqwala kunye nokukhukuliseka.

•Isiqu seValve: Isiqu sevalvu sidlulisela amandla, sidibanisa i-actuator kwidiski ukuze sikwazi ukujikeleza. Ngokwesiqhelo senziwe ngentsimbi engagqwaliyo, enoyilo oluqinisiweyo nolukhulu lwezicelo ezinkulu, ezinoxinzelelo oluphezulu ukuthintela ukugoba okanye ukuguquka.

•Isihlalo seValve:Isihlalo sokutywina sibalulekile ekuvalekeni okuqinileyo. Siza ngerabha ethambileyo okanye izinto zesinyithi ezitywinayo, ezihambelana kakuhle nediski ukuze kungabikho kuvuza.

•I-Actuator: Izixhobo zoqhagamshelo lwe-actuator ziquka iziphatho, ii-worm gears, kunye nee-electric/pneumatic actuators. Zibonelela nge-torque efunekayo yokuvula nokuvala, zilungele ukusebenza ngesandla kunye nolawulo olukude oluzenzekelayo. Zonke izixhobo zisebenza kunye ukuqinisekisa ukusebenza okuzinzileyo, ukuvalwa okuthembekileyo, kunye nokulawulwa ngokuchanekileyo kwevalvu yebhabhathane.

1.2 Uhlalutyo lweMigaqo yoYilo lweSakhiwo seValve yeButterfly eSebenza ngokuPhezulu

Ivalvu yebhabhathane esebenza kakuhle yivalvu yebhabhathane ebhalwe ngobuchule obuchanekileyo, efanelekileyo ukulawula okanye ukulawula ukuhamba kwamanzi kunye noxinzelelo kwiindawo ezifana namanzi empompini, amanzi emizi-mveliso, amanzi amdaka, umoya, i-HVAC, igesi yesixeko, kunye ne-LPG. Xa ivaliwe, ivalvu ayifumani manzi.

Isakhiwo sesihlalo sevalvu sinoyilo lwe-COS curve sealant, olunciphisa ukungqubana phakathi kwediski kunye nesihlalo, lunciphisa i-actuator torque, kwaye lwandise ubomi besihlalo. Inkqubo yalo yokutywina ifana neyevalvu ene-double-eccentric. Umphezulu wokutywina wediski ungqukuva, uqinisekisa ukunxibelelana okuthambileyo ngexesha lokutywina. Ukungqubana okunciphileyo, ingakumbi kwi-shaft seal, kwandisa kakhulu ubomi benkonzo yesihlalo. Indandatho yokugcina isinyithi ngaphakathi kwindandatho yesihlalo ivala ngokuzenzekelayo nasiphi na isithuba phakathi kwesiqu kunye nendandatho yesihlalo xa isiqu siphantsi kwamandla angalinganiyo, okususa amathuba okuvuza kwe-axial.

•Ijika le-COS: Uyilo lokutywinwa kwe-COS curve luqinisekisa ukuba akukho torque yonyuka ngaphambi kokuba kutywinwe. Ngexesha lokutywinwa, idiski inxibelelana neringi yesihlalo ngaxeshanye kumjikelezo opheleleyo we-360°, inciphisa ukungqubana, inciphisa i-torque, yandisa ubomi besihlalo, kwaye igcina kungekho kuvuza ngexesha lokusebenza ixesha elide. Ukungqubana okunciphileyo kunye ne-torque kuvumela ukusetyenziswa kwee-actuators ezinamandla aphantsi, kunciphisa iindleko zomsebenzisi.

•Idiski eMachined eSpherically: Idiski yenziwe ngomatshini yaya kwimo epheleleyo yesangqa, apho yonke inxalenye yomphezulu wokutywina yenza icandelo lesangqa. Zombini idiski kunye neringi yesihlalo zicutshungulwa kwisangqa esifanayo, nto leyo ebangela ukuba kungabikho sithuba sininzi kwaye kungabikho kungqubana. Idiski ijikeleza kakuhle, nokuba kukwiindawo zokutywina ze-axial phezulu nasezantsi. Nangona idibana, iindawo zokutywina zithambile kakhulu, zinciphisa i-torque kwaye ziphucula ukusebenza kokutywina.

•Ivalvu yeButterfly ene-PTFE eSebenza ngokuPhezulu: Le valve inomngxuma womzimba ogcwele i-PTFE kwaye isetyenziswa kakhulu ekutyeni, kwi-biopharmaceutical, kwi-elektroniki, nakwezinye iinkqubo zococeko zokulawula okanye ukulawula ukuhamba kunye noxinzelelo lweziselo ezahlukeneyo, kunye nakwizicelo zoshishino lweekhemikhali ezibandakanya ii-asidi ezinamandla, ii-alkali ezinamandla, kunye neegesi ezirhabaxa kakhulu. Inika ukuqina okuphezulu, ukusebenza kakuhle kokuvala, kunye nokumelana nokugqwala okugqwesileyo, okufikelela ekungavuzini nanye xa ivaliwe.

•Uyilo lweType ye-I: Uyilo lweringi yesitywino lugcina irabha kunye neTeflon zizimele kodwa zihambelana, nto leyo ephucula ukusebenza kwesitywino. Ukusetyenziswa kwerabha kongeza ukuthamba kwesitywino ngelixa kunciphisa ubungakanani berabha efunekayo, kususa umngcipheko wokuxinana kweediski kwindawo evaliweyo ngenxa yokwanda kwerabha ngenxa yokunyuka kwamaqondo obushushu.

Ukusebenza Okuphuculweyo Kokuvala Uyilo Olutsha Lwe-Butterfly Valve Esebenza Kakhulu:

a. I-PFA lining enobukhulu obuyi-3 mm okanye ngaphezulu ithintela ukungena kweegesi ezahlukeneyo kwaye inika ukumelana okunamandla kokugqwala.

b. Iisprings zongezwa kwiibhokisi zokupakisha eziphezulu nezisezantsi ukuze koyiswe imiphumo yokuguquguquka kobushushu ekutywinweni.
