Yini Engasetshenziswa Ama-Flanged Ball Valve: Izinhlelo Zokusebenza

Iyini i-Flanged Ball Valve

I-valve yebhola e-flangeduhlobo lwevalvu yokujika ngekota esebenzisa ibhola elingenalutho, elinembobo, nelijikelezayo ukulawula ukugeleza koketshezi. Igama elithi “flanged” libhekisela endleleni yokuxhuma yevalvu: inama-flange kuzo zombili izinhlangothi, aboshwe kuma-flange ahambisanayo kumapayipi noma imishini. Lo mklamo uqinisekisa ukuxhumana okuqinile, okuvimbela ukuvuza, okwenza ama-valve ebhola aflange abe afaneleke kakhuluumfutho ophezulufuthiizinga lokushisa eliphezuluizinhlelo zokusebenza.

Ibhola elingaphakathi kwevalvu linembobo edlula phakathi nendawo. Uma ivalvu ivuliwe, imbobo ihambisana nesiqondiso sokugeleza, okuvumela uketshezi ukuthi ludlule. Ukujikeleza isibambo noma i-actuator ngama-degree angu-90 kuvala ivalvu, kubeka imbobo iqonde ngqo ekugelezeni futhi kuyivimbe. Amavalvu ebhola ahlanganisiwe aziwa ngokuthembeka kwawo, ukusebenza okusheshayo, kanye nokwehla okuncane kwengcindezi.

Usayizi, Izinto, kanye Nobubanzi Bokucindezela Kwama-Flanged Ball Valve

Ububanzi Bosayizi

Ama-valve ebhola ahlanganisiwe atholakala ngobukhulu obahlukahlukene ukuze avumelane nezinhlelo ezahlukene zamapayipi:

• Ububanzi:Ngokuvamile kusukela½ intshi (DN15)ku-Amasentimitha angu-48 (DN1200).
• Osayizi Abavamile:Ama-2″, 4″, 6″, 8″, 10″, kanye no-12″ asetshenziswa kabanzi ezinhlotsheni zezimboni.

Izinketho Zezinto Ezibalulekile

Ukukhethwa kwezinto kuncike ohlotsheni loketshezi, izinga lokushisa, kanye nezimo zemvelo:

1. Izinto Zomzimba:
   • Insimbi Yekhabhoni (i-WCB):Ngezinhlelo zokusebenza ezijwayelekile.
   • Insimbi Engagqwali (SS304, SS316):Ayikwazi ukumelana nokugqwala ezindaweni zamakhemikhali noma zasolwandle.
   • Insimbi Ehlanganisiwe (WC6, WC9):Ukumelana nokushisa okuphezulu.
   • Insimbi Ephindwe Kabili:Kwabezindaba abanolaka njengamanzi olwandle.
   • I-PVC/CPVC:Ilula futhi ayigqwali ezinhlelweni ezisebenzisa umfutho ophansi.
2. Izinto Zokubopha Isihlalo Nesivalo:
   • I-PTFE (i-Teflon):Ukumelana namakhemikhali kanye nokungqubuzana okuphansi.
   • Izihlalo Zensimbi (Insimbi Engagqwali):Ukuqina kokushisa okuphezulu.
   • Ama-Elastomer (EPDM, NBR):Ngezinhlelo zamanzi negesi.

Ububanzi Bokucindezela

Ama-valve ebhola ane-flanged alinganiswa ngokusekelwe kumakilasi okucindezela ajwayelekile:

• Amakilasi e-ASME:Ikilasi 150, 300, 600, 900, 1500, kanye no-2500.
• Ububanzi Bokucindezela:KusukelaI-PSI engu-150 (ibha eyi-10)ku-I-PSI engu-5,000 (ibha engu-345).

Ukuhlukaniswa kwama-Flanged Ball Valve

Ama-valve ebhola afakwe i-flanged ahlukaniswe ngokususelwa kumklamo kanye nokusebenza kwawo:

1. Ngokwesakhiwo:

   • Imbobo Egcwele (Imbobo Egcwele):Ububanzi bembobo buhambisana ne-ID yepayipi, okunciphisa ukuvinjelwa kokugeleza.
   • Imbobo Encishisiwe (Ibhore Elijwayelekile):Imbobo encane yezinhlelo zokusebenza ezibiza kakhulu.

2. Ngomklamo:

   • Ibhola Elintantayo:Ibhola libanjwe izihlalo ezimbili endaweni yalo; lifanele izinhlelo eziphansi komfutho.
   • Ibhola Elifakwe I-Trunnion:Ibhola liboshwe nge-trunnion ukuze liqine ngokucindezela okuphezulu.

3. Ngomsebenzi:

   • Izindlela Ezimbili (Amachweba Amabili):Ukulawula okuyisisekelo kokuvula/ukuvala ukugeleza.
   • Izindlela Ezintathu (Izimbobo Ezi-3):Ukuze kuphambukiswe noma kuxutshwe ukugeleza kwamanzi.
   • Ama-V-Port Ball Valve:Ukulawula ukugeleza okunembile ngembobo enomumo ongu-V.

Izinzuzo zama-Flanged Ball Valve

1. Umklamo Ongavuzi:Ukuxhumeka okugoqekile kuqinisekisa ukuvalwa okuqinile ngaphansi kwengcindezi ephezulu.
2. Ukuqina:Ukwakhiwa okuqinile kuyamelana nokuguguleka, ukugqwala, kanye nokucindezeleka kokushisa.
3. Ukusebenza Okusheshayo:Ukujikeleza ngamadigri angu-90 kwenza kube lula ukuvula/ukuvala ngokushesha.
4. Ukugcinwa Okuphansi:Izingxenye ezimbalwa ezihambayo zinciphisa izidingo zenkonzo.
5. Ukuguquguquka:Iyahambisana noketshezi, amagesi, kanye ne-slurry.
6. Ukugeleza Kwezinhlangothi Ezimbili:Ifanele izinhlelo ezidinga ukuguqulwa kokugeleza.

Ukusetshenziswa kwama-Flanged Ball Valve

Ama-valve ebhola afakwe i-flanged asetshenziswa kuzo zonke izimboni ngenxa yokuzivumelanisa nezimo kwawo:

1. Uwoyela negesi:

   • Ukuhlukaniswa kwamapayipi, ukulawula inhloko yemithombo, kanye nezinhlelo zokuhlanza.
   • Izinto zokwakha: Insimbi yekhabhoni noma insimbi ephindwe kabili yokumelana negesi emuncu.

2. Ukucubungula Amakhemikhali:

   • Ukuphatha uketshezi oluqothulayo olufana nama-asidi kanye nezinyibilikisi.
   • Amavalvu afakwe i-PTFE ukuze avumelane namakhemikhali.

3. Ukwelashwa Kwamanzi:

   • Ukuphakelwa kwamanzi kamasipala, izinhlelo zokuthutha indle, kanye nezindawo zokukhipha usawoti emanzini.
   • Izivalo ze-EPDM zokuhambisana namanzi aphuzwayo.

4. Ukukhiqizwa Kwamandla:

   • Imigqa yomusi, izinhlelo zokupholisa, kanye ne-turbine bypass.
   • Amavalvu okucindezela okuphezulu kwamanzi okuphakelwa kwebhoyila.

5. Izinhlelo ze-HVAC:

   • Amanzi abandayo, izintambo zokushisa, kanye nokulawula amafriji.

6. Imboni Yasolwandle:

   • Ukupholisa amanzi olwandle, izinhlelo ze-ballast, kanye nokudluliselwa kukaphethiloli.

Yini Engasetshenziswa Ama-Flanged Ball Valve

Ama-valve ebhola ane-flanged asebenza indima ebalulekile ekuphathweni koketshezi:

• Ukuzihlukanisa:Vala ukuhamba kwamanzi ngesikhathi sokulungiswa noma izimo eziphuthumayo.
• Ukulawulwa Kokugeleza:Imiklamo ye-V-port ivumela ukugoqa.
• Ukuphathwa Kwengcindezi:Melana nokuphakama komfutho ophezulu.
• Ukuhlanganiswa Kwezinhlelo Eziningi:Xhuma amaphampu, amathangi, kanye namapayipi ngokusebenzisa ama-flange.

Ikhono labo lokusingatha izimo ezimbi kakhulu (isib. amazinga okushisa acwebezelayo, ukusaphazeka okunamandla) kubenza babaluleke kakhulu ezimbonini ezidinga ukuthembeka nokuphepha.

Isiphetho

Amavalvu ebhola ahlanganisiweziyizingxenye eziguquguqukayo, ezihlala isikhathi eside, nezisebenza kahle zezinhlelo zokulawula uketshezi. Ngezinketho ezisukela ku-½” kuya ku-48″, izinto ezifana nensimbi engagqwali kanye ne-PTFE, kanye nezilinganiso zokucindezela ezifika ku-5,000 PSI, zihlangabezana nezidingo zezimboni ezisukela ku-oyili negesi kuya ekuhlanzweni kwamanzi. Ukwakheka kwazo okugoqekile kuqinisekisa ukufakwa okuphephile, kuyilapho ukucushwa okuthuthukisiwe (isb., okufakwe ku-trunnion, okunezindlela ezintathu) kwandisa ukusebenza kwazo. Kungakhathaliseki ukuthi kuhlukanisa amapayipi, ukulawula ukugeleza, noma ukuphatha umusi ocindezelayo ophezulu, ama-valve ebhola agoqekile aletha ukusebenza okungenakuqhathaniswa ezinhlelweni ezibalulekile.
