Ama-valve e-Butterfly e-API 609: Umhlahlandlela Ophelele Wezobuchwepheshe

Iyini i-API 609 Butterfly Valve

Amavalvu e-Butterfly e-API 609ama-valve ezimboni aklanyelwe ngokwezindinganiso ze-American Petroleum Institute (API). Anikeza ukuvala okumangalisayo, ukumelana nokugqwala, kanye nokuthembeka kwengcindezi kumapayipi kawoyela, igesi, amakhemikhali, kanye ne-petrochemical. Lawa ma-valve e-butterfly asebenza kahle kakhulu ahlangabezana nezilinganiso zomhlaba wonke zokuphepha nokusebenza kahle.

Ukuqonda Amazinga e-API 609

I-API 609 iyindinganiso yokuklama yama-valve e-butterfly ajwayelekile aseMelika akhishwe yi-Isikhungo Se-American PetroleumIgama layo eliphelele lithi “Amavalvu ebhabhathane: Uhlobo oluphindwe kabili, uhlobo lwe-Lug- kanye nohlobo lwe-Wafer". Inguqulo yakamuva okwamanje inguqulo ka-2021."

Inguqulo yakamuva ejwayelekile ye-API 609 yi-‌API 609-2021 (Uhlelo lwesi-8), evuselela amazinga okuklama amavalvu evemvane, yandisa imininingwane yamavalvu evemvane e-flange ephindwe kabili, i-lug kanye ne-wafer, futhi inezela izigaba zamavalvu evemvane e-butt-weld.
Okuqukethwe okujwayelekile kokubuyekezwa

•I-Butt weld butterfly valve: Inguqulo ka-2021 yengeza izidingo zomklamo wamavalvu ebhabhathane ashintshwayo nge-butt-weld ekuqaleni, okuthuthukisa kakhulu imininingwane ejwayelekile yezindlela zokuxhuma amavalvu ebhabhathane.

‌•Ukulungiswa kwemigomo yobuchwepheshe: Ezinye izincazelo zobuchwepheshe zilungiselelwe ngokwemikhuba yemboni, kodwa imininingwane ethile yobuchwepheshe ayidalulwanga ngokuningiliziwe olwazini lomphakathi.

Okuqukethwe okuyinhloko kwe-API 609 standard kuhlanganisa imiklamo yamavalvu evemvane enama-flanged double, lug-type, kanye ne-wafer. Le standard ichaza:

1. Izidingo Zokuklama:Ukulungiswa kwe-fluid dynamics ukuze kube nokumelana okuncane kokugeleza kanye nokulawula okunembile.

2. Izinto Zokusebenza Nokukhiqiza: Imininingwane yemizimba yama-valve, ama-disc (amapuleti evemvane), iziqu, kanye nezivalo.

3. Izinqubo Zokuhlola:Ukuhlolwa kokucindezela, ukuvala, kanye nokugeleza okuphoqelekile ukuqinisekisa ikhwalithi.

4. Iziqondiso Zokunakekela:Izinqubo zokuhlola, ukugcoba, nokulungisa.

Indlela Ama-valve E-Butterfly Asebenza Ngayo

A ivalvu yebhabhathaneIdiski ka-'s ijikeleza ngo-90° izungeze i-axis yayo ukuze ilawule ukugeleza. Izici ezibalulekile:

•Isikhundla Esivulekile: Idiski ihambisana nokugeleza (ukwehla okuncane kwengcindezi).

•Isikhundla Esivaliwe: Idiski iqonde ngqo ekugelezeni (ukuvala okuqinile njengebhamuza).

•Ukusebenza: Isebenzisa izibambo eziphathwa ngesandla, opharetha begiya, noma izinhlelo ezizenzakalelayo (zomoya/ezikagesi).

Izingxenye Eziyinhloko Zama-Butterfly Valve

1. Umzimba Wevalvu

Idizayini encane ye-cylindrical; itholakala ngezitayela ze-wafer, i-lug, noma i-flanged.

2. Idiski (Ipuleti)

Ipuleti elincane, eliyindilinga (insimbi engagqwali evamile) lokulawula ukugeleza kwamanzi.

3. Isiqu

Idiski yokuxhumanisa umgodi onamandla aphezulu ne-actuator.

4. Indandatho Yesihlalo (Ukuvala)

Izihlalo ze-EPDM, i-PTFE, noma zensimbi ukuze zisebenze kahle ngaphandle kokuvuza.

5. I-Actuator

Amadrayivu enziwe ngesandla, aqhutshwa ngomoya, aqhutshwa ngamanzi, noma kagesi.

Izinhlobo zama-Butterfly Valve

By I-Eccentricity

I-Concentric Butterfly Valve: Amanzi/umoya ophansi.

I-Single Eccentric Butterfly Valve: Ukungqubuzana okuncishisiwe; kulungele ukudla/imithi.

Ivalvu Yebhabhathane Ephindwe Kabili Engajwayelekile: Ivaliwe ngensimbi; iphatha umusi ongu-425°C.

Ivalvu Yebhabhathane E-Eccentric Ethathu: Akukho ukuvuza; imelana no-700°C/25MPa.

Ngohlobo Lokuxhumeka

Ivalvu Yesivikelo Sebhathabhatha Esiyindilinga:Incane, iyabiza kahle.

I-Lug Butterfly Valve:Ukusebenziseka kahle komugqa ophakathi.

Ivalvu Yebhabhathane Ene-Flanged:Ukuqina komfutho ophezulu.

Ngokwezinto Ezibalulekile

I-Valve Yesivivane Sensimbi Engagqwali:Ayikwazi ukumelana nokugqwala kwamakhemikhali.

I-Carbon Steel Butterfly Valve:Umzimba wevalvu owenziwe yiCarbon Steel, iValve Disc ingaba yi-WCB, CF8, CF8M, CF3, CF3M.

I-Iron Butterfly Valve:Umzimba wevalvu yi-Ductile Iron noma i-Cast Iron, i-Valve Disc izoba yi-Ductile Iron+Ni, CF8, CF8M, CF3, CF3M.

I-valve ye-Butterfly Esebenza Kakhulu:Isihlalo sevalvu yi-RPTFE/PTFE, futhi isihlalo sevalvu sifakwe epuletini levalvu futhi singasuswa futhi sifakwe esikhundleni saso epayipini, sihlala siklanywe ngendlela ye-Double Eccentric noma ye-Triple eccentric.

Amavalvu e-Butterfly vs. Amavalvu e-Ball vs. Amavalvu e-Gate

Ukukhetha i-Valve ye-Butterfly Efanele

• Imidiya Eyonakalisayo:Ivalvu yebhabhathane yensimbi engagqwali enophahla lwe-PTFE.

•Izinga Lokushisa Eliphezulu/Ingcindezi:Ivalvu ye-butterfly ye-API 609 enezinhlangothi ezintathu, enesihlalo sensimbi.

•Ukusetshenziswa Kwenhlanzeko:Ivalvu yebhabhathane elicwebezelayo elinezimbozo ze-EPDM.

•Ukuzenzakalela:Ama-actuator kagesi/omoya.

Izicelo Zemboni

•Uwoyela/igesi:Amavalvu e-butterfly e-API 609 emapayipini okuhlanza.

•Izitshalo Zikagesi:Amavalvu asebenza kahle kakhulu okulawula umusi.

•Ukwelashwa Kwamanzi:Amavalvu ebhabhathane e-Wafer ezindaweni zokupompa.

•Ukumba:Imiklamo engagugi yokuthutha udaka.

Kungani Kufanele Ukhethe Ama-valve Ahambisana Ne-API 609?

Iziqinisekiso zesitifiketi se-API 609:
