1.Ni ikinyugunyugu cya EN593 ni iki?
Umuyoboro w'ikinyugunyugu wa EN593 bivuga icyuma cy'ikinyugunyugu cyakozwe kandi gikozwe hakurikijwe BS BS 593: 2017, cyiswe “Indangagaciro z'inganda - Indangagaciro rusange z'ikinyugunyugu.” Ibipimo ngenderwaho byashyizwe ahagaragara n’ikigo cy’Ubwongereza gishinzwe ubuziranenge (BSI) kandi gihuza n’ibipimo by’Uburayi (EN), bitanga urwego rwuzuye rwo gushushanya, ibikoresho, ibipimo, gupima, no gukora ibinyugunyugu.
EN593 ibinyugunyugu birangwa numubiri wibyuma byububiko hamwe nuburyo butandukanye bwo guhuza, nkubwoko bwa wafer, ubwoko bwa lug, cyangwa bubiri. Ibinyugunyugu birashobora gukora munsi yumuvuduko nubushyuhe butandukanye. Ibipimo ngenderwaho byemeza ko indangagaciro zujuje ibisabwa byumutekano, kuramba, guhuza, no kwizerwa.
2. Ibyingenzi byingenzi bya EN593 Ibinyugunyugu
* Igihembwe-gihindura ibikorwa: Ibinyugunyugu bikora mukuzenguruka disiki ya valve dogere 90, bigafasha kugenzura byihuse kandi neza.
* Igishushanyo mbonera: Ugereranije nu marembo y amarembo, imipira yumupira, cyangwa umubumbe wisi, indabyo zinyugunyugu ziremereye kandi zibika umwanya, bigatuma biba byiza mugushiraho bifite umwanya muto.
* Impera zinyuranye zihuza: Ziboneka muri wafer, lug, flange ebyiri, flange imwe, cyangwa U-bwoko bwibishushanyo, bihujwe na sisitemu zitandukanye.
* Kurwanya ruswa: Yubatswe kuva murwego rwohejuru rwibikoresho birwanya ruswa kugirango harebwe igihe kirekire mubidukikije.
* Umuyoboro muke: Yashizweho kugirango ugabanye ibisabwa bya torque, ituma automatike hamwe na moteri ntoya no kugabanya ibiciro.
* Gufunga zeru-zeru: Imyanya myinshi ya EN593 igaragaramo intebe yoroshye ya elastike cyangwa intebe zicyuma, itanga kashe ya bubble kugirango ikore neza.
3. BS EN 593: 2017 Ibisobanuro birambuye
Kuva 2025, BS EN 593 isanzwe yemeza verisiyo ya 2017. EN593 nubuyobozi bwuzuye kububiko bwikinyugunyugu, bugaragaza byibuze ibisabwa mubishushanyo, ibikoresho, ibipimo, hamwe no kugerageza. Ibikurikira nintangiriro irambuye kubintu nyamukuru byibisanzwe, bishyigikiwe namakuru yinganda.
3.1. Igipimo gisanzwe
BS EN 593: 2017 ikoreshwa mubyuma byikinyugunyugu kubintu rusange, harimo kwigunga, kugenzura, cyangwa kugenzura imigezi. Irimo ubwoko butandukanye bwa valve hamwe numuyoboro wanyuma uhuza, nka:
* Ubwoko bwa Wafer: Bishyizwe hagati ya flanges ebyiri, zigaragaza imiterere yoroheje kandi yoroheje.
* Ubwoko bwa Lug: Ibiranga urudodo rwinjizwamo umwobo, bikwiriye gukoreshwa kumpera.
* Impande ebyiri: Ibiranga flanges integral, ihindagurika neza kuri flanges.
* Imirongo imwe: Ibiranga flanges yibanze kumurongo wa valve hagati.
* U-Ubwoko: Ubwoko bwihariye bwa wafer-ubwoko bwa valve ifite imitwe ibiri ya flange kandi igereranya imbonankubone.
3.2. Umuvuduko nubunini
BS EN 593: 2017 yerekana umuvuduko nubunini buringaniye bwikinyugunyugu:
* Ibipimo by'ingutu:
- PN 2.5, PN 6, PN 10, PN 16, PN 25, PN 40, PN 63, PN 100, PN 160 (Urutonde rw’ibitutu by’i Burayi).
- Icyiciro 150, Icyiciro 300, Icyiciro 600, Icyiciro 900 (amanota ya ASME).
Ingano yubunini:
- DN 20 kugeza DN 4000 (diameter nominal, hafi 3/4 cm kugeza kuri 160).
3.3. Igishushanyo nogukora ibisabwa
Ibipimo ngenderwaho byerekana ibipimo ngenderwaho byihariye kugirango tumenye neza imikorere ya valve:
* Ibikoresho byumubiri: Valve igomba gukorwa mubikoresho byuma nkibyuma byangiza, ibyuma bya karubone (ASTM A216 WCB), ibyuma bitagira umwanda (ASTM A351 CF8 / CF8M), cyangwa umuringa wa aluminium (C95800).
* Igishushanyo cya disiki ya disiki: Disiki ya valve irashobora kuba hagati cyangwa kuri eccentric (offset kugirango ugabanye intebe na torque).
* Ibikoresho byicaro bya Valve: Intebe za Valve zishobora kuba zikozwe mubikoresho byoroshye (nka reberi cyangwa PTFE) cyangwa ibikoresho byuma, bitewe nibisabwa. Intebe za elastike zitanga kashe ya zeru, mugihe intebe zicyuma nazo zigomba kwihanganira ubushyuhe bwinshi no kwangirika usibye kugera kuri zeru.
* Ibipimo imbona nkubone: Ugomba kubahiriza ibipimo bya EN 558-1 cyangwa ISO 5752 kugirango byemeze guhuza na sisitemu yo kuvoma.
* Ibipimo bya flange: Bihujwe nibipimo nka EN 1092-2 (PN10 / PN16), ANSI B16.1, ASME B16.5, cyangwa BS 10 Imbonerahamwe D / E, bitewe n'ubwoko bwa valve.
* Acuator: Imyanda irashobora gukoreshwa nintoki (ikiganza cyangwa garebox) cyangwa igahita ikora (pneumatike, amashanyarazi, cyangwa hydraulic actuator). Hejuru ya flange igomba kubahiriza ISO 5211 kugirango ishobore kwishyiriraho ibikorwa bisanzwe.
3.4. Kwipimisha no Kugenzura
Kugirango umenye neza imikorere, BS EN 593: 2017 bisaba ibizamini bikomeye:
* Ikizamini cya Hydraulic test: Igenzura ko valve idafite amazi kumuvuduko wihariye.
* Ikizamini cyibikorwa: Iremeza imikorere myiza hamwe numuriro ukwiye mubihe byagereranijwe.
* Ikizamini cyo kumeneka: Emeza gufunga-gufunga intebe ya elastike ukurikije EN 12266-1 cyangwa API 598.
* Icyemezo cy'Ubugenzuzi: Uwayikoze agomba gutanga raporo y'ibizamini no kugenzura kugira ngo agenzure niba yubahiriza ibipimo.
3.5. Porogaramu ya EN593 Ibinyugunyugu
* Gutunganya Amazi: Kugenzura no gutandukanya urujya n'uruza rw'amazi meza, amazi yo mu nyanja, cyangwa amazi mabi. Ibikoresho birwanya ruswa hamwe nibitwikiro bituma bibera ahantu habi.
* Inganda zikora imiti n’ibikomoka kuri peteroli: Gukoresha amazi yangirika nka acide, alkalis, hamwe nuwashonga, ukungukirwa nibikoresho nkintebe za PTFE hamwe na disiki ya valve ya PFA.
* Amavuta na gaze: Gucunga umuvuduko ukabije, ubushyuhe bwo hejuru cyane mumiyoboro, inganda, hamwe na platifomu yo hanze. Igishushanyo-cya-offset gishyigikirwa kuramba muri ibi bihe.
* Sisitemu ya HVAC: Kugenzura imigendekere yumwuka, amazi, cyangwa firigo muri sisitemu yo gushyushya no gukonjesha.
* Amashanyarazi: Kugenga ibyuka, amazi akonje, cyangwa andi mazi mumashanyarazi.
* Inganda z’ibiribwa n’imiti: Gukoresha ibikoresho byubahiriza FDA (nka PTFE na EPDM yemewe na WRA) kugirango harebwe imikorere idafite umwanda kandi byujuje ubuziranenge bw’isuku.
3.6. Kubungabunga no Kugenzura
Kugirango ukore neza igihe kirekire, EN593 ibinyugunyugu bisaba kubungabunga buri gihe:
* Kugenzura inshuro: Kugenzura buri mezi atandatu kugeza kumwaka umwe kugirango wambare, ruswa, cyangwa ibibazo byimikorere.
* Amavuta: Kugabanya guterana no kwagura igihe cya valve.
* Intebe ya Valve hamwe nubugenzuzi bwa kashe: Kugenzura ubusugire bwintebe ya elastike cyangwa ibyuma kugirango wirinde kumeneka.
* Kubungabunga Acuator: Menya neza ko pneumatike cyangwa amashanyarazi idafite imyanda kandi ikora bisanzwe.
4. Kugereranya nubundi bipimo API 609
Mugihe BS EN 593 ikoreshwa mugukoresha inganda rusange, itandukanye nibisanzwe API 609, igenewe cyane cyane amavuta na gaze. Itandukaniro ryibanze ririmo:
* Kwibanda ku gusaba: API 609 yibanda ku bidukikije bya peteroli na gaze, mu gihe BS EN 593 ikubiyemo inganda nini, harimo gutunganya amazi n’inganda rusange.
* Ibipimo byumuvuduko: API 609 mubisanzwe ikubiyemo icyiciro cya 150 kugeza mucyiciro cya 2500, mugihe BS EN 593 ikubiyemo PN 2.5 kugeza PN 160 na Class 150 kugeza 900.
* Igishushanyo: API 609 ishimangira ibikoresho birwanya ruswa kugirango bihangane n’ibihe bibi, mu gihe BS EN 593 yemerera guhitamo ibintu byoroshye.
* Kwipimisha: Ibipimo byombi bisaba kugeragezwa gukomeye, ariko API 609 ikubiyemo ibisabwa byinyongera kubishushanyo mbonera birwanya umuriro, bifite akamaro mugukoresha peteroli na gaze.

Igipimo cya BS EN 593: 2017 gitanga urwego rukomeye rwo gushushanya, gukora, no kugerageza ibyuma byikinyugunyugu, byemeza ko byiringirwa, umutekano, nibikorwa muburyo butandukanye bwa porogaramu. Mugukurikiza ibisabwa mubisanzwe kugirango igipimo cyumuvuduko, ingano yubunini, ibikoresho, hamwe nogupima, ababikora barashobora kubyara indangagaciro zujuje ubuziranenge bwisi.
Waba ukeneye ubwoko bwa wafer, ubwoko bwa lug, cyangwa ibinyugunyugu byikinyugunyugu bibiri, kubahiriza ibipimo bya EN 593 bituma habaho kwishyira hamwe, kuramba, no kugenzura neza amazi.
