Umehluko Phakathi Kwe-Low-End kanye Ne-Mid-High-End Soft-End Soft Butterfly Valves

1. Ukukhetha Okubalulekile

Amavalvu Aphansi

• Izinto Zomzimba/Idiski: Ngokuvamile sebenzisa izinsimbi ezingabizi kakhulu njengeInsimbinoma insimbi engahlanganisiwe ye-carbon, engase intule ukumelana nokugqwala ezindaweni ezinokhahlo.
• Izindandatho zokuvala: Yenziwe ngama-elastomer ayisisekelo njengeI-NR (irabha yemvelo)noma i-EPDM yezinga eliphansi, enomkhawulo wokumelana namakhemikhali nokubekezelela izinga lokushisa (isb, ≤80°C / 176°F).
• Umphini: Ivamise ukwakhiwa nge-carbon steel evamile ngaphandle kokwelashwa okungaphezulu, ejwayele ukugqwala ezimeni ezimanzi noma ezine-asidi.

Amavalvu Aphakathi-Phezulu Aphezulu 

• Izinto Zomzimba/Idiski: Sebenzisa izinto ze-premium njengensimbi engagqwali (SS304/316), i-ductile iron, noma i-aluminium bronze ukuze uthole ukumelana nokugqwala okuphakeme namandla okusebenza.
• Izindandatho zokuvala: Sebenzisa ama-elastomer asebenza kahle kakhulu njenge-EPDM ethobela i-FDA, i-NBR, i-PTFE, noma i-Viton®,umnikelo brukuhambisana kwamakhemikhali we-oader (isb., ukumelana namafutha, ama-asidi, noma izincibilikisi) kanye namazinga okushisa aphezulu (-20°C kuya ku-150°C / -4°F kuya ku-302°F).
• Umphini: Yenziwe ngensimbi engagqwali (SS410/316) enezindawo ezipholishiwe noma ezimboziwe (isb, i-nickel plating) ukuvimbela ukuguga nokuvuza.

1. Idizayini Yesakhiwo Nokukhiqiza

Amavalvu Aphansi

• Umklamo Owenziwe Lula: Izakhiwo ezigxilile eziyisisekelo noma ezine-eccentric eyodwa ezinokunemba okulinganiselwe kokuvala. I-disc nesihlalo kungase kube nomshini oqinile, okuholela ekungqubuzaneni okuphezulu ne-torque.
• Umhlangano: Ivamise ukukhiqizwa ngobuningi ngokulawulwa kwekhwalithi okuncane, okuholela ekubekezeleleni okungahambisani. Izilinganiso zokuvuza zingase zehluleke ukuhlangabezana namazinga aqinile (isb., ukudlula izimfuneko ze-ANSI B16.104 Class VI).
• Ukwenza:Ivamise ukubhangqwa nezibambo zamanuwali ezibiza kancane noma ama-actuator ayisisekelo kagesi, antula ukuqina ukuze asebenze njalo.

Amavalvu Aphakathi-Phezulu Aphezulu

• Idizayini Ethuthukile: Isiciizakhiwo ezi-double-eccentric noma ezintathu-eccentricukunciphisa ukungqubuzana, ukuthuthukisa ukusebenza kahle kokuvala, nokunciphisa ukuguga. Isibonelo, imiklamo e-double-eccentric idala "umphumela wokushada" wokuvala okuqinile.
• Precision Manufacturing: Ifakwe ngemishini ye-CNC enembayo ephezulu, iqinisekisa ukunyakaza kwediski okubushelelezi kanye nokuxhumana kophawu olulungile. Amazinga okuvuza avame ukuhlangana noma adlule i-ISO 15848-1 (isb, Ikilasi A eliqinile ngebhamuza).
• Ukwenza: Ihambisana nama-actuator eprimiyamu (ama-pneumatic, hydraulic, noma ama-actuator kagesi ahlakaniphile) wezinhlelo zokusebenza ezinesivinini esikhulu, zomjikelezo omkhulu. Amanye amamodeli afaka ama-positioners noma izinzwa zempendulo zokuzenzakalela.

3. Ukusebenza Nokwethenjelwa

Amavalvu Aphansi

• Imikhawulo yengcindezi/yezinga lokushisa: Ifanele amasistimu anengcindezi ephansi (isb, ≤PN10 / Ikilasi 125) kanye namazinga okushisa amancane. Ingase yehluleke ezindaweni ezinengcindezi ephezulu (isb, >PN16) noma izinga lokushisa elidlulele (-10°C ukuya ku-90°C) ezindaweni.
• Impilo Yesevisi: Ifushanisiwe ngenxa yokuqina kwempahla ebuthakathaka kanye namaphutha edizayini, edinga ukulungiswa njalo noma ukushintshwa (isb, imijikelezo engu-10,000–20,000).
• Ingozi yokuvuza: Amathuba aphezulu okushintsha uphawu noma ukugqwala kwe-shaft, okuholela ekuvuzeni kwemvelo noma ukwehluleka kwesistimu.

Amavalvu Aphakathi-Phezulu Aphezulu

• Imikhawulo yengcindezi/yezinga lokushisa: Idizayinelwe amasistimu okucindezela okumaphakathi kuya phezulu (isb, PN16–PN40 / Ikilasi 150–Ikilasi 300) kanye namazinga okushisa abanzi (-30°C kuya ku-200°C / -22°F kuya ku-392°F).
• Impilo Yesevisi: Iklanyelwe ukwethembeka kwesikhathi eside, nempilo yomjikelezo idlula imisebenzi eyi-100,000. Amanye amamodeli e-premium anikeza iziqinisekiso zempilo yonke.
• Ukulawula Ukuvuza: Izigxivizo ezithuthukisiwe nezivimbela ukuqhunyiswa zinciphisa izingozi zokuvuza, zizenze zifanelekele izinhlelo zokusebenza ezibucayi njengezinhlelo zegesi noma ukuphatha uketshezi oluyingozi.

4. Izicelo

Amavalvu Aphansi

• Ifanele: Izinhlelo zokusebenza ezingabalulekile, ezinobungozi obuncane ezinezidingo eziyisisekelo zokulawula ukugeleza, njenge:
• Izinhlelo zokuhlinzeka ngamanzi ezindaweni zokuhlala
• I-HVAC ductwork elula
• Ukuchelela okunengcindezi ephansi noma i-drainage
• Gwema Ukusebenzisa Ngaphakathi: Amapayipi ezimboni anengcindezi ephezulu, imidiya ebolayo, noma izindawo ezibucayi zokuphepha (isb., uwoyela negesi, imithi).

Amavalvu Aphakathi-Phezulu Aphezulu

• Ilungele: Ukufuna izicelo zezimboni nezentengiso, okuhlanganisa:
• Izitshalo zokucubungula amakhemikhali (uketshezi olubolayo)
• Ukukhiqizwa kokudla nesiphuzo (izindinganiso zenhlanzeko)
• Ukukhiqiza amandla (izinga lokushisa eliphezulu)
• Uwoyela negesi (izidingo zokuvikela ukuqhuma)
• Amazinga Abalulekile: Ivamise ukuqinisekiswa ku-ISO, API, ASME, noma i-ATEX ngokuhambisana nemithetho yokuphepha yamazwe ngamazwe nekhwalithi.

5. Izindleko Nokunakekela

Amavalvu Aphansi

• Izindleko Zokuqala: Ishibhe kakhulu (ngo-20–50% ngaphansi kwamamodeli asezingeni eliphakathi), okuwenza athandeke kumaphrojekthi azwela isabelomali.
• Isondlo: Izindleko eziphakeme zesikhathi eside ngenxa yokushintshwa kwezimpawu njalo, ukugcotshwa kwe-shaft, noma ukulungiswa kokugqwala.
• Ingozi Yesikhathi Sokuphumula: Kuvame kakhulu ekuhlulekeni okungalindelekile, okuholela ekulahlekelweni kokukhiqiza kuzilungiselelo zezimboni.

Ukukhetha iValve Elungile (isb.Ivalve ye-TWS)

• Isiphetho Esiphansi: Ifanele ukusetshenziswa kwesikhathi esifushane, okungabalulekile lapho izindleko ziyinkinga enkulu.
• Mid-High-End: Faka imali kulokhu ukuze uthole ukwethembeka, ukuphepha, nokusebenza kwesikhathi eside ezinhlelweni eziyinselele. Ngaso sonke isikhathi cabangela uhlobo lwemidiya, izimo zokusebenza, kanye nezidingo zokuthobela imithetho lapho ukhetha ivalvu.

 

Lo mehluko ugqamisa ukuthi kungani ama-valve amaphakathi asezingeni eliphezuluI-D371X-16Qzikhethwa ezimbonini ezibeka phambili ukuphepha nokusebenza kahle, kuyilapho izinketho ezisezingeni eliphansi zinikeza izidingo eziyisisekelo, eziqhutshwa yizindleko.
