Ama-Big Size Ball Valve: Ukuhlukaniswa kanye Nezicelo

Ama-Big Size Ball Valve: Umhlahlandlela Wokuhlukaniswa Nokukhethwa Komkhiqizi

Ama-valve ebhola ayizingxenye ezibalulekile ezinhlelweni zamapayipi ezimboni, aklanyelwe ukulawula ukugeleza koketshezi, amagesi, noma ama-slurry. Isakhiwo sawo esilula kodwa esiqinile—esinebhola elijikelezayo elinembobo—siqinisekisa ukuvalwa okuthembekile kanye nokwehla okuncane kwengcindezi. Kodwa uma amaphrojekthi edingaama-valve ebhola amakhulu(ngokuvamile echazwa njengama-valve anobubanzi obungamasentimitha angu-12/300 mm noma ngaphezulu), ukukhetha umklamo ofanele kanye nomenzi kuba yinto ebalulekile. Lo mhlahlandlela uhlola ukuhlukaniswa kwama-valve ebhola anobubanzi obukhulu kanye nendlela yokukhetha umhlinzeki othembekile.

Ayini Ama-Ball Valve Amakhulu

Ama-valve amakhulu ebhola angama-valve asebenza kanzima aklanyelwe ukusetshenziswa kokugeleza okuphezulu ezimbonini ezifana nowoyela negesi, ukwelashwa kwamanzi, ukukhiqizwa kukagesi, kanye nokucubungula amakhemikhali. Ububanzi bawo obukhulu (amasentimitha angu-12–60+) buwavumela ukuthi abhekane nokucindezeleka okukhulu, amazinga okushisa, kanye nezidingo zevolumu.

Izici Eziyinhloko:

• Ukwakhiwa Okuqinile:Kwenziwe ngezinto ezifana nensimbi engagqwali, insimbi yekhabhoni, noma i-alloy ukuze kumelane nezimo ezinzima.
• Ukuvalwa Okuthuthukisiwe:Izihlalo eziqinile (isib. i-PTFE, i-metal-to-metal) zivimbela ukuvuza ezindaweni ezinomfutho ophezulu.
• Izinketho Zokusebenza:Ukusebenza ngesandla, ngomoya, nge-hydraulic, noma ngogesi kokulawula okuzenzakalelayo.

Ukuhlukaniswa kwama-Big Size Ball Valve

Ukuqonda izinhlobo zamavalvu kuqinisekisa ukusebenza kahle kwezinhlelo ezithile:

1.Ngomklamo

• Amavalvu Ebhola Elintantayo:Ibhola libanjwa endaweni yalo ngokucindezelwa okuvela ezihlalweni zamavalvu. Lifanele izinhlelo zokucindezela eziphansi kuya kweziphakathi.
• Amavalvu Ebhola Afakwe I-Trunnion:Ibhola liboshwe nge-trunnion shaft, okunciphisa ukuguguleka kwesihlalo. Lifanele amapayipi amakhulu anengcindezi ephezulu.

InothiAmavalvu ebhola amakhulu ngokuvamile amavalvu ebhola afakwe ku-trunnion.

2.Ngokwezinto Ezibalulekile

• Insimbi engagqwali:Ayikwazi ukumelana nokugqwala ezindaweni zamakhemikhali noma zasolwandle.
• Insimbi Yekhabhoni:Kusebenza kahle kakhulu ezinhlelweni zikawoyela negesi ezinomfutho ophezulu.
• Ama-Cryogenic Alloys:Yenzelwe amazinga okushisa angaphansi kwezinga-zero kuzinhlelo zokusebenza ze-LNG.

3.Ngokuphela Kokuxhumeka

• I-Flanged:Ivamile kumapayipi amakhulu ukuze kube lula ukuwafaka.
• Okushiselwe:Ihlinzeka ngesivalo esihlala njalo, esingavuzi sezinhlelo ezibalulekile.

Indlela Yokukhetha Umkhiqizi We-Big Size Ball Valve Ofanele

Ukukhetha umkhiqizi onokwethenjelwa kuqinisekisa isikhathi eside, ukuphepha, kanye nokuthobela imithetho. Nakhu okufanele kubekwe phambili:

1.Ulwazi Lomkhakha Nodumo

Funa abakhiqizi abanomlando oqinisekisiwe wokukhiqiza ama-valve amakhulu emkhakheni wakho. Hlola izitifiketi (isb., i-API 6D, i-ISO 9001) kanye nobufakazi bamakhasimende.

2.Amakhono Okwenza Ngokwezifiso

Amaphrojekthi amakhulu avame ukudinga izixazululo ezenzelwe wena. Qinisekisa ukuthi umhlinzeki unikeza:

• Osayizi bebhore elenziwe ngokwezifiso, izilinganiso zokucindezela, kanye nezinto zokwakha.
• Izembozo ezikhethekile (isb., ezilwa nokugqwala, eziphephile emlilweni).

3.Ukuqinisekisa ikhwalithi

Qinisekisa ukuthi umenzi ulandela izinqubo zokulawula ikhwalithi eziqinile, okuhlanganisa:

• Ukuhlolwa okungabhubhisi (NDT) kobuqotho bokushisela.
• Ukuhlolwa kwengcindezi ukuqinisekisa ukusebenza ngaphansi kwezimo ezimbi kakhulu.

4.Usekelo Lwangemva Kokuthengisa

Khetha umlingani ohlinzeka ngosekelo lobuchwepheshe, izinsizakalo zokulungisa, kanye nezingxenye ezisele ezitholakala kalula.

5.Izindleko vs. Inani

Nakuba amanani entengo ebalulekile, beka phambili inani lesikhathi eside. Ama-valve ashibhile angonga izindleko kusengaphambili kodwa angabangela ukwehluleka njalo kanye nesikhathi sokungasebenzi.

Imicabango Yokugcina

Ama-valve ebhola amakhuluzibalulekile ezinhlelweni zezimboni ezidinga amandla okugeleza aphezulu kanye nokuqina. Ngokuqonda ukuhlukaniswa kwazo kanye nokubambisana nomkhiqizi onolwazi, ungaqinisekisa ukusebenza kahle kanye nokuphepha. Njalo beka phambili izitifiketi zekhwalithi, izinketho zokwenza ngokwezifiso, kanye nokusekelwa kwangemva kokuthenga lapho uhlola abahlinzeki.

Ukuze uthole ulwazi olwengeziwe ngokukhethwa kwama-valve, hlola iziqondiso zethu zobuchwepheshe noma uxhumane nethimba lethu lobunjiniyela ukuze uthole izincomo ezenzelwe wena.
