Umhlahlandlela ophelele wobunjiniyelaAmavalvu e-Butterfly asebenza ngomoya—ehlanganisa izindlela zokushayela ze-actuator,imiklamo ye-offset, ukubalwa kwe-torque, ukufakwa kwe-ISO 5211, kanye nezindinganiso ze-API 609 zokwenza izinto ngokuzenzakalela kwezimboni.
Isifinyezo Esiphezulu: Iyini i-Pneumatic Actuated Butterfly Valve?
1. Isimiso Sokusebenza kanye Nemishini Yomshini Womoya
Okuzenzakalelayoivalvu yebhabhathane elinomoyakuguqula ukucindezela komoya (ngokuvamile ibha engu-4.0–8.0umoya wesitshalo) ekujikelezweni komgodi womshini. Umoya ocindezelwe usebenza ngokumelene nama-piston angaphakathi noma ama-diaphragmngaphakathi kwendlu ye-actuator, ukushayela ishafti ejikelezayo engu-90° exhunywe kwidiski yevalvu nge-
I-ISO 5211isikhombikubona se-flange esiphezulu.
Izinhlobo zezinhlelo ze-Butterfly Valve Actuator Drive
Ukukhetha okulungilei-actuator ye-butterfly valvekuncike kujika lokukhipha i-torque, imvamisa yomjikelezo, kanye nosayizi webhore le-valve:
- Ama-Actuator e-Rack kanye ne-Pinion:Ama-piston amabili anama-racks egiya ahlanganisiwe aletha umugqa oqondilei-torque kuyo yonke i-stroke engu-90°. I-footprint encane kanye nokujikeleza okusheshayo kubenza babe imboniindinganiso yamavalvu azenzakalelayo aqala ngokukhanya kuya kokuphakathi (DN40 kuya ku-DN300).
- Ama-Actuator e-Scotch Yoke:I-joke pin-and-block assembly ikhiqiza i-torque engaqondileiphrofayili enomphumela ophezulu kakhulu ekugcineni kwe-stroke (ukuphuma kanye nezihlalo). Le nzuzo yomshini yenzazilungele kakhulu izihlalo ezinkulu, ezisebenza kahle kakhulu, noma ezifakwe insimbiamavalvu ebhabhathane aphindwe kathathu
(Kusukela ku-DN350 kuya ku-DN1200+).
Izindlela Zokusebenza Zomoya: Ukusebenza Okuphindwe Kabili vs. Ukubuya Kwentwasahlobo
| Ukucushwa kwe-Actuator | Indlela Yokusebenza | Isimo Sesenzo Esiphephile Sokwehluleka |
|---|---|---|
| I-Double Acting (DA) | Kudinga umoya ocindezelwe ePort A ukuze uvuleke futhi iPort B ivale. | Ukwehluleka endaweni:Ibamba indawo yamanje lapho umoya ulahlekile. |
| Ukubuya Kwentwasahlobo (i-SR / i-Single Acting) | Umfutho womoya ushayela ohlangothini olulodwa ngenkathi ucindezela iziphethu zangaphakathi. Iziphethu zishayela uhlangothi oluphambene. | Ukuphepha Kokuhluleka Kwemishini:Ishintshela ngokuzenzakalelayo ku-Ukuvala Okungaphumeleli (FC) or Ukuvula Okungaphumeleli (FO)lapho umoya uphela. |
Ukuqonda Okuyinhloko Kobunjiniyela
Ngezinhlelo zokusebenza ezibalulekile zokuphepha (isb., izinhlelo zokuvala eziphuthumayo), cacisa njaloama-actuator okubuyisa intwasahlobongesikhundla esifanele sokuphepha. Ama-actuator asebenza kabili ayathandwa ekulawuleni ukulawula laphoUkugcina isikhundla ngesikhathi sokulahlekelwa ugesi kuyamukeleka.
2. Ukwakhiwa Komzimba We-Valve kanye Nezinhlobo Zokuklama Kwe-Offset
Ukususwa komshini kwe-disc shaft kunquma i-torque yokusebenza, ukungqubuzana kwesihlalo, kanye namakhono okushisakwei-valve yebhabhathane yohlobo lwe-actuator:
1. Amavalvu Ovemvane Aqinile (Ahlala Eqinile)
Isiqu sibekwe phakathi kwediski kanye nesihlalo. Sisebenzisa ama-liners athambile elastomeric (EPDM, NBR,I-Viton, noma i-PTFE) okufanele ifezekisweUkuvalwa kwe-ANSI/FCI 70-2 Class VI okungenalutho. Kufanelekile kakhulungezinsizakalo zamanzi, umoya, i-HVAC, kanye namakhemikhali athambile afinyelela ku-16 bar kanye no-150°C.
2. Amavalvu e-Butterfly e-Double Offset (asebenza kahle kakhulu)
Umgodi usuka kokubili esikhaleni sesihlalo kanye nasesikhaleni sepayipi. Lokhu kungezwani okubili kubangela idiski"ukuphakamisa" esihlalweni ngesikhathi sokujikeleza, ukunciphisa ukungqubuzana, ukwehlisa i-torque yokuhlala, kanye nokwelula isihlaloimpilo yesevisi. Itholakala ngezihlalo ezithambile ze-PTFE/RPTFE noma izindandatho zokuvala zensimbi eziguquguqukayo ukuze kube nomfutho ophakathi nendawo
imigqa ye-steam kanye nenqubo.
3. Amavalvu e-Butterfly Ahlala Ngensimbi Ane-Offset Ezintathu (TOBV)
Ifaka i-engeli yesithathu ye-offset ehlanganiswe ne-geometry yekhoni yesihlalo. Lokhu akuhlikihliki, isenzo se-camumklamo ufinyelela ukujikeleza okungenazingxabano kanye nezihlalo eziqinile zensimbi nensimbi (i-Stellite / Laminated StainlessInsimbi). Yenzelwe isevisi enzima, amazinga okushisa aphezulu afinyelela ku-550°C+, uketshezi olucijile, kanye nokuphepha emlilweni.imisebenzi.
Izinketho Zokuqeda Ukuxhumeka
- Uhlobo lwe-Wafer:Umzimba omncane ubanjwe phakathi kwama-flange epayipi ngama-through-bolts. Isisindo esincane kakhulu kanye nendawo ephansi kakhulu.
- Uhlobo lwe-Lug:Ama-lug anezintambo emzimbeni afana namaphethini e-flange bolt. Ivumela isevisi engapheli kanye nokugcinwa komugqa ongezansi.
- Uhlobo Oluphindwe Kabili:Ama-flange ahlanganisiwe kuzo zombili izinhlangothi; okuphoqelekile kuma-diameter amakhulu (DN300+) kanye nokufakwa kokucindezeleka kwamapayipi agqitshwe noma anzima.
3. Izesekeli Ze-Loop Yokulawula Ezenzakalelayo
Ukuguqula ivalvu evamile yebhabhathane ephefumulayo ibe yinto yokulawula yokugcina ehlakaniphile, inhlanganiselaizesekeli zomoya zifakwe ngqo ngeI-NAMURfuthiI-ISO 5211izixhumi zokuxhumana:
Iphakheji Yezesekeli Ezijwayelekile Zokuzenzakalelayo
- Izikhombisi-ndlela Zamavalvu E-Electro-Pneumatic (4–20mA / HART / Fieldbus):Lawula umoyaingcindezi esekelwe ekufakweni kwesignali yokulawula ukuze kulawulwe ukugeleza okunembile.
- Amavalvu e-Solenoid (I-NAMUR Mount enezindlela ezintathu noma ezimbili):Lawula isiqondiso sokunikezwa komoyangomsebenzi wokuzihlukanisa lapho uvala iloli. Izinketho ze-SIL 3 ziyatholakala emigqeni yokuvala ukuphepha.
- Amabhokisi Okushintsha Umkhawulo (Angavimbeli Ukuqhuma / IP67):Nikeza isibonakaliso esibonakalayo sendawofuthi udlulise impendulo kagesi evulekile/evaliwe ku-PLC noma ku-DCS.
- Abalawuli Bezihlungi Zomoya (i-AFR):Hlunga izinto ezincane ezifinyelela kuma-microns angu-5 kanyegcina umfutho womoya ozinzile ukuze uvikele izivalo zangaphakathi ze-actuator.
- Ukweqa Okungasuswa Ngokuzenzakalelayo:Amabhokisi egiya lesandla afakwe phakathi kwevalvu kanyei-actuator evumela ukusebenza ngesandla ngesikhathi somoya ocindezelwe ngokuphelele noma ukwehluleka kukagesi.

5. Imibuzo Evame Ukubuzwa (Imibuzo Evame Ukubuzwa Ngobunjiniyela)
Q1: Ingabe i-valve ye-butterfly ye-pneumatic actuator ingasetshenziswa ukulawula ukugeleza okunembile?
Yebo. Ngokufaka ivalvu yebhabhathane eliyi-double offset noma eliyi-concentric nge-digital electro-pneumatic positioner(isignali engu-4–20mA), i-assembly isebenza njenge-valve yokulawula ephumelelayo yokulawula ukugeleza okuphezulu nokucindezela okuphansiamapayipi okulahla.
Umbuzo 2: Iyini inzuzo eyinhloko yevalvu yebhabhathane yohlobo lwe-actuator kunevalvu yebhola?
Amavalvu ebhabhathane asebenza ngomoya alula kakhulu, mancane kakhulu ngobukhulu bobuso nobuso, futhi aqinile kakhuluengabizi kakhulu ngobukhulu bemigqa emikhulu (DN200 / 8-intshi nangaphezulu) uma kuqhathaniswa nama-valve ebhola anosayizi ofanayo.
UMBUZO 3: Kungani indinganiso yokufaka ye-ISO 5211 ibalulekile ku-actuator ye-butterfly valve?
I-ISO 5211 ichaza amaphethini ebholidi afanayo, ubukhulu bomgodi wokushayela, kanye nobukhulu beflange. Lokhu kuqinisekisa ukulinganaukushintshana, okuvumela ama-actuator omoya avela kubakhiqizi abahlukahlukene ukuthi afake ngqo eziqwini zamavalvungaphandle kwama-bracket angokwezifiso.
UMBUZO 4: Uyini umehluko phakathi kwamavalvu ebhabhathane ahlala ethambile kanye namavalvu ensimbi ahlala enziwe ngensimbi?
Amavalvu athambile asebenzisa izihlalo ze-elastomeric noma ze-PTFE ukuze kufinyelelwe ukuvala okungavuzi lutho emazingeni okushisa aphansi.(ngokuvamile ≤150°C). Amavalvu ahlala ngensimbi (okuphindwe kathathu) asebenzisa ukuvala insimbi ibe yinsimbi futhi angakwazi ukumelanaamazinga okushisa afinyelela ku-550°C+, okwenza afanelekele umusi, uwoyela oshisayo, kanye nezinsizakalo ze-cryogenic.
