Ivalvu yeButterfly eQhelekileyo kathathu

Ivalvu yeButterfly ye-Offset kathathu: Isishwankathelo esipheleleyo seMveliso

Yintoni iValve yeButterfly e-Triple Offset

A ivalvu yebhabhathane ephindwe kathathu(TOBV) yivalvu yemizi-mveliso esebenza kakuhle kakhulu eyenzelwe ukulawula ukuhamba kwamanzi ngokuchanekileyo kwizicelo ezifuna amandla. Ijiyometri yayo eyahlukileyo inciphisa ukuguguleka, iqinisekisa ukutywinwa okungenamaqamza, kwaye isebenza ngokufanelekileyo phantsi kobushushu obugqithisileyo kunye noxinzelelo. Ngokungafaniyo nesiqhelo.iivalvu zebhabhathane, i-TOBV isebenzisauyilo oluphindwe kathathuukuphelisa ukungqubana phakathi kwediski nesihlalo ngexesha lokusebenza, okwenza ukuba ilungele iinkonzo ezibalulekileyo.

Ukuqonda uyilo lwe-"Triple Offset"

Igama elithi "i-triple offset" libhekisa kwii-geometric offsets ezintathu ezahlukeneyo ekwakhiweni kwevalvu:

1. I-Offset yokuqala: I-shaft yevalvu ibekwe ngasemva komgca ophakathi wesihlalo, nto leyo evumela idiski ukuba ijikeleze ngaphandle kokuchukumisa isihlalo.

2. I-Offset yesibini: I-shaft ibekwe ecaleni komgca ophakathi wombhobho, nto leyo eyenza intshukumo efana ne-cam ukuze isebenze kakuhle.

3. I-Offset yesithathu: Umphezulu wesihlalo ugobile (iprofayili yekhonikhi), oqinisekisa isiphumo sokudibanisa esiphucula ukutywinwa njengoko ivalvu ivala.

Olu yilo lususa ukungqubana okutyibilikayo, lunciphisa ukuguguleka, kwaye luqinisekisa ukuba akukho kuvuza kwaphela nokuba lusetyenziswe ixesha elide.

- Ukuwelda Ngempundu:Kwiinkqubo zemibhobho ezihlala zihleli, ezisemgangathweni ophezulu.

Izixhobo

- Umzimba/Ukucheba:Intsimbi engatyiwayo (SS316, SS304), intsimbi ye-duplex, intsimbi yekhabhoni, i-Inconel®, i-Hastelloy®.

- Isihlalo:Izitywino eziqinileyo zesinyithi ukuya kwisinyithi okanye izinto ezidityanisiweyo ezilaminethiweyo (umz., igrafiti + intsimbi engagqwaliyo).

- Idiski:Idla ngokugqunywa nge-stellite okanye i-ceramic ukuze ikwazi ukumelana nokurhawuzelelwa.

Iimeko Zokusebenza

- Uluhlu lobushushu:-196°C ukuya kwi-850°C (-320°F ukuya kwi-1,562°F).

- Imidiya:Iyahambelana nomphunga, iihydrocarbon, iikhemikhali ezibolayo, kunye nolwelo olune-cryogenic.

- Amashishini:Ioyile negesi, ukuveliswa kombane, ukucutshungulwa kweekhemikhali, i-LNG, kunye neenqwelo-moya zaselwandle.

Iingenelo zeeValve zeButterfly ze-Offset ezintathu

1. Akukho Kuvuza:Uyilo olunezihlalo zesinyithi luhambelana ne-ISO 5208 Leakage Class A (engangenisi bubbles).

2. Ubomi beNkonzo ende:Ukungabikho kokungqubana kuqinisekisa ukuguguleka okuncinci, nokuba emva kwamawakawaka emijikelo.

3. Ulondolozo oluphantsi:Akukho mfuneko yokuthambisa okanye yokutshintsha isihlalo rhoqo.

4. Ukuguquguquka:Iyakwazi ukumelana namaqondo obushushu agqithisileyo, uxinzelelo, kunye neendaba ezirhabaxa.

Izicelo

- Iindawo zokuCoca ioyile:Ukwahlulwa kunye nokulawulwa kweoyile ekrwada, igesi, kunye neemveliso ezicociweyo.

- Izityalo zoMbane:Ukwahlulwa komphunga kwiiturbines nakwiibhoyila.

- Izityalo zeKhemikhali:Ukuphatha ii-asidi, ii-alkali, kunye nolwelo olunamandla.

- Iinkqubo zeCryogenic:Ukugcinwa kunye nokuthuthwa kwe-LNG.

Ukuthobela imithetho kunye neziqinisekiso

- Imigangatho:I-API 609, i-ASME B16.34, i-ISO 5752.

- Uyilo Olukhuselekileyo Emlilweni:Iyahambelana neI-API 607/API 6FAkwizicelo ezingatshiyo.

Ivalvu yebhabhathane e-triple offset idibanisa ubunjineli obuchanekileyo kunye nezixhobo eziqinileyo ukubonelela ngokuthembeka okungenakuthelekiswa nanto kwiinkqubo ezibalulekileyo zoshishino. Uyilo lwayo oluphambili lujongana nemida yeevalvu zemveli, nto leyo eyenza ukuba ibe lukhetho olukhethwayo kwiinkqubo zanamhlanje zokusebenza okuphezulu.
