I-China Triple Eccentric Butterfly Valve mveliso kunye nabavelisi

Ivalvu yeButterfly eNxantathu eZimeleyo

Umfanekiso obonisiweyo weValve yeButterfly eNcinci eneMigca emithathu

Inkcazo emfutshane:

Iivalvu yebhabhathane engaqhelekanga kathathu— ekwaziwa ngokuba yivalvu yebhabhathane ephindwe kathathu — yivalvu yebhabhathane ehleli ngentsimbi esebenza kakhulu eyenzelwe ukusetyenziswa kweenkqubo zokujikeleza ezinoxinzelelo oluphezulu, ubushushu obuphezulu, kunye nokujikeleza rhoqo apho iivalvu eziqhelekileyo ezihleli kamnandi zingasetyenziswa khona. Ezi zixhobo zokulinganisa ezintathu zejometri zisusa konke ukungqubana phakathi kwediski kunye nesihlalo ngexesha lokuvula nokuvala, nto leyo ebangela ukuba isihlalo singagugi ngomjikelo ngamnye. Isihlalo siyinxalenye yomzimba wevalvu, sigqunywe ngezinto ezichasene nokugugiswa kunye nee-engile zokuhlala ezilungiselelweyo, ngelixa iiringi zokuvala ezithambileyo okanye zesinyithi-kwisinyithi zinamathele kwidiski — zibonelela ngokumelana okuphezulu nokutshaqeka kobushushu, iincopho zoxinzelelo, kunye nokugqwala. Yenziwe kwi-API 609, ubuso ngobuso i-ANSI B16.10, ubushushu boxinzelelo ngokwe-ASME B16.34. Uvavanyo loxinzelelo lwe-ANSI Class 150/300/600/900. Uluhlu lobungakanani DN50–DN1500 (2″–60″). Izinto zomzimba ziquka intsimbi yekhabhoni, intsimbi engatyiwayo, iMonel, kunye neHastelloy. Iinketho zesihlalo: isitywina esithambileyo esineengqimba ezininzi okanye intsimbi-kwisinyithi. INortech ngumvelisi kunye nomthengisi weevalvu zeebhabhathane ezi-eccentric ezintathu ohamba phambili eTshayina.

Ivalvu yebhabhathane e-Eccentric Triple — Imboniso yokwazisa

Yintoni iValve yeButterfly e-Triple Eccentric?

Iivalvu yebhabhathane engaqhelekanga kathathu— ekwaziwa ngokuba yi-triple offset butterfly valve — yi-butterfly valve esebenza kakhulu eyenzelwe ukusetyenziswa kokuqhuba ngebhayisekile okunoxinzelelo oluphezulu, ubushushu obuphezulu, kunye nokujikeleza rhoqo. Ngelixa ii-butterfly valves ezinerabha egxile kwi-concentric zibonelela ngokuthembeka okuqinisekisiweyo kunye nokusebenza kakuhle kweendleko kwinkonzo ngokubanzi, azifanelekanga kwiimeko ezinzima ezifana nobushushu obuphezulu okanye ii-frequency zokusebenza eziphezulu kakhulu. Ii-butterfly valves eziqhelekileyo ezihlala ixesha elide zijongana neminye yale mida, kodwa ukusebenza kwazo kokuvala phantsi kweemeko ezinzima bekusoloko kuyinkxalabo. I-butterfly valve e-triple eccentric valve yaphuhliswa ngokukodwa ukuze yoyise le mida.

Isihlalo siyinxalenye yomzimba wevalvu, sinee-engile zokuhlala ezilungiselelwe kakuhle kunye neengubo ezichasene nokuguguleka ezifanelekileyo kwizigidi zemijikelo yokusebenza. Ukwakhiwa kwentsimbi engagqwaliyo kunika ukumelana nokugqwala, kwaye izixhobo ezishushu kakhulu ziyafumaneka kwiindawo ezishushu kakhulu. Iiringi zokutywina ezithambileyo ezinamalaya amaninzi okanye iiringi zokutywina zentsimbi eqinileyo zinamathele kwidiski, nto leyo eyenza ivalvu imelane kakhulu nokutshayiswa kubushushu, iincopho zoxinzelelo, kunye nokugqwala xa kuthelekiswa neevaluvu zebhabhathane eziqhelekileyo.

Akukho kuvuza kufumaneka ngendandatho yokutywina yentsimbi engagqwaliyo edityanisiweyo efakwe kwidiski. I-geometry eyahlukileyo ephindwe kathathu engaqhelekanga ivumela ukujikeleza kwe-engile yasekunene ngaphandle kokungqubana — kususa lonke unxibelelwano phakathi kwesihlalo kunye nendandatho yokutywina ngexesha lokubetha kwe-90°. Oku kunciphisa kakhulu i-torque yokusebenza, okuvumela ukuba kuchazwe i-actuator encinci nengabizi kakhulu.

Xa ivala, indlela yokudlulisa inyusa i-torque ukuze ibonelele ngokutywinwa okuqinileyo nokuhlawulelwayo. Le ndlela yokudlulisa iphucula ukusebenza kokutywinwa ngaxeshanye kwaye yandisa ubomi benkonzo yevalvu.

Ivalvu yebhabhathane ephindwe kathathu — inkcazo yoyilo

Uyilo lwe-offset oluphindwe kathathu

1

I-shaft yevalvu ibekwe ngasemva komgca ophakathi wediski, ivumela iringi yokutywina ukuba ivaleke ngokupheleleyo kwisihlalo sevalvu sonke ngaphandle kokuphazamiseka.
2

Umgca osembindini weshaft yevalvu uthintelwe kumgca osembindini wepayipi kunye nomgca osembindini wevalvu, nto leyo esusa ukuphazamiseka ngexesha lokuvula nokuvala.
3

I-axis yekhoni yesihlalo iyaphambuka kumgca ophakathi wevalvu, isusa ukungqubana kuyo yonke i-stroke epheleleyo kwaye ifezekisa ukutywinwa okufanayo koxinzelelo olujikeleze lonke umjikelo wesihlalo.

Istroke yokungqubana kwe-Zero Akukho kuvuza Isihlalo esisuka kwisinyithi ukuya kwisinyithi okanye esinamaleko amaninzi DN50–DN1500 I-ANSI 150/300/600/900 Ubushushu obuphezulu kunye noxinzelelo oluphezulu
