Iivalvu zeButterfly ze-API 609: Isikhokelo soBugcisa esipheleleyo

Yintoni i-API 609 Butterfly Valve

Iivalvu zeButterfly ze-API 609ziivalvu zemizi-mveliso ezenzelwe imigangatho ye-American Petroleum Institute (API). Zinikezela ngokutywinwa okugqwesileyo, ukumelana nokugqwala, kunye nokuthembeka koxinzelelo kwimibhobho yeoyile, igesi, iikhemikhali kunye ne-petrochemical. Ezi valve zebhabhathane ezisebenza kakuhle zihlangabezana nemilinganiselo eqinileyo yamazwe ngamazwe yokhuseleko kunye nokusebenza kakuhle.

Ukuqonda iMigangatho ye-API 609

I-API 609 ngumgangatho woyilo lweevalvu zeebhabhathane ezisemgangathweni zaseMelika ezikhutshwe yiIZiko lePetroleum laseMelikaIgama layo elipheleleyo ngu “Iivalvu zeButterfly: Uhlobo oluphindwe kabini, oluneLug kunye nolweWafer". Inguqulelo yamva nje ngoku yinguqulelo ka-2021."

Inguqulelo yamva nje ye-API 609 yi-‌API 609-2021 (uHlelo lwesi-8), ehlaziya imigangatho yoyilo lwevalvu yebhabhathane, yandisa iinkcukacha zeevalvu zebhabhathane ezijijekileyo, i-lug kunye ne-wafer, kwaye yongeza iziqendu zeevalvu zebhabhathane ezijijekileyo.
Umxholo wohlaziyo oluqhelekileyo

•Ivalvu yebhabhathane ye-Butt weldInguqulelo ka-2021 yongeza iimfuno zoyilo lweevalvu zebhabhathane ezifakwe i-butt-weld kwisiseko sokuqala, nto leyo ephucula ngakumbi iinkcukacha ezisemgangathweni zeendlela zokudibanisa iivalvu zebhabhathane.

‌•Uhlengahlengiso lwemigaqo yobugcisaEzinye iinkcukacha zobugcisa ziphuculwe ngokweendlela zoshishino, kodwa iinkcukacha ezithile zobugcisa azichazwanga ngokweenkcukacha kulwazi lukawonke-wonke.

Okuphambili komgangatho we-API 609 kuquka uyilo lweevalvu zebhabhathane ezine-double-flanged, lug-type, kunye ne-wafer butterfly. Lo mgangatho uchaza oku kulandelayo:

1. Iimfuno zoYilo:Ukulungiswa kwe-fluid dynamics ukuze kubekho ukumelana okuncinci kokuhamba kwamanzi kunye nolawulo oluchanekileyo.

2. Izinto kunye noMveliso: Iinkcukacha zemizimba yeevalvu, iidiski (iipleyiti zebhabhathane), iziqu, kunye nezitywini.

3. IiProtokholi zoVavanyo:Uvavanyo loxinzelelo oluyimfuneko, ukuvala, kunye nokuhamba kwamanzi ukuqinisekisa umgangatho.

4. Izikhokelo Zokugcinwa:Iinkqubo zokuhlola, ukuthambisa, kunye nokulungisa.

Indlela Iivalvu Zebhabhathane Ezisebenza Ngayo

A ivalvu yebhabhathaneIdiski ka-'s ijikeleza i-90° ijikeleze i-axis yayo ukuze ilawule ukuhamba. Iimpawu eziphambili:

•Indawo evulekileyo: Idiski ihambelana nokuhamba (ukwehla okuncinci koxinzelelo).

•Indawo eValiweyo: Idiski ijonge ngqo kwi-flow (ukuvala okuqinileyo njengeqamza).

•Ukusebenza: Isebenzisa izibambo zesandla, abaqhubi begiya, okanye iinkqubo ezizenzekelayo (zomoya/zombane).

Izinto eziphambili zeevalvu zebhabhathane

1. Umzimba weValve

Uyilo oluqinileyo oluyi-cylindrical; lufumaneka kwiindlela ze-wafer, i-lug, okanye i-flanged.

2. Idiski (Ipleyiti)

Ipleyiti ebhityileyo, ejikelezayo (intsimbi engatyiwayo eqhelekileyo) yokulawula ukuhamba kwamanzi.

3. Isiqu

Idiski yokudibanisa umngxuma onamandla aphezulu kwi-actuator.

4. Indandatho yesihlalo (Ukutywina)

Izihlalo ze-EPDM, ze-PTFE, okanye zesinyithi ukuze zisebenze ngaphandle kokuvuza.

5. I-Actuator

Iidrives ezenziwe ngesandla, ezisebenzisa umoya, ezisebenzisa i-hydraulic, okanye ezisebenzisa umbane.

Iintlobo zeeValve zeButterfly

Ngu-Eccentricity

Ivalvu yebhabhathane egxile kwiConcentric: Amanzi/umoya ophantsi koxinzelelo.

Ivalvu yeButterfly eNye engaqhelekanga: Ukungqubana okunciphileyo; ilungele ukutya/ikhemesti.

Ivalvu yeButterfly ephindwe kabini engaqhelekanga: Itywinwe ngentsimbi; iphatha umphunga ongama-425°C.

Ivalvu yeButterfly eNxantathu eZimeleyo: Akukho kuvuza; imelana ne-700°C/25MPa.

Ngohlobo loQhagamshelo

Ivalvu yebhabhathane yeWafer:Incinci, ingabizi kakhulu.

Ivalvu yebhabhathane yeLug:Inkonzo ephakathi.

Ivalvu yebhabhathane eFlanged:Uzinzo oluphezulu loxinzelelo.

Ngokwezinto eziphathekayo

Ivalvu yeButterfly yeNtsimbi Engagqwaliyo:Ayimelani nokugqwala kwiikhemikhali.

Ivalvu yeBhabhathane yentsimbi yekhabhoni:Umzimba wevalvu owenziwe yiCarbon Steel, iValve Disc ingaba yiWCB, CF8, CF8M, CF3, CF3M.
