1. Incazelo Eyisisekelo Nesakhiwo
Ivalvu yebhabhathane ethambile egoqekile (eyaziwa nangokuthi "ivalvu yebhabhathane ephakathi nendawo") iyivalvu ejikelezayo ejikelezayo eyenzelwe ukuvula/ukuvala noma ukulawula ukugeleza kwamapayipi. Izici zayo eziyinhloko zifaka:
I-Concentric Design: Isiqu se-valve, idiski, nesihlalo ziqondaniswe e-eksisi emaphakathi efanayo, kwakheka isakhiwo esilula nesihlangene.
Indlela Yokuvala Ethambile: I-flexible elastomeric seal (isb., irabha, i-EPDM, i-NBR) ihlanganiswe emzimbeni wevalvu noma esihlalweni, okunikeza i-tight seal ukuvimbela ukuvuza.
Iziphetho Ezinamaphiko: I-valve ifakwe ukuxhumana okuphendukile, okuvumela ukufakwa kalula kumapayipi okuthobelana namazinga afana ne-ANSI, i-DIN, noma i-JIS.
2.Izingxenye Ezibalulekile
3. Isimiso Sokusebenza
Isikhundla esivulekile: I-disc izungeza i-90° ukuvumelanisa nesiqondiso sokugeleza, ukunciphisa ukwehla kwengcindezi nokuvumela ukugeleza okugcwele.
Indawo Evaliwe: Idiski izungeza emuva ukuze ucindezele uphawu oluthambile, idale ukuvala okuqinile. Idizayini ye-concentric incike ekuguquguqukeni okunwebekayo kophawu ukuze kufinyelelwe ekubekweni uphawu, okuyenza isebenze kakhulu ezinhlelweni ezinomfutho ophansi.
4. Izici Eziyinhloko Nezinzuzo
Ukuvalwa Okuqinile: Izigxivizo ezithambile zinikeza ukumelana nokuvuza okuhle kakhulu, ngokuvamile zihlangabezana nezindinganiso eziqinile zebhamuza (isb, ANSI B16.104 Class VI, ISO 15848-1).
I-Low Torque Operation: Idizayini egxile kanye nesigxivizo esivumelana nezimo kunciphisa ukungqubuzana, okuvumela ukusebenza okulula okwenziwa ngesandla noma ukusetshenziswa ngama-actuator angasindi.
Compact and Lightweight: Uma kuqhathaniswa namavalvu esango noma embulunga, amavalvu ovemvane agxilile mancane futhi kulula ukuwafaka ezindaweni ezilinganiselwe.
Izindleko: Isakhiwo esilula nokusetshenziswa kwezinto eziphansi kuzenza zithengeke ngezidingo eziyisisekelo zokulawula ukugeleza.
Ukuhambelana Kwemidiya Okuhlukahlukene: Ifanele amanzi, umoya, uwoyela, uketshezi olungagqwali, nemidiya eyimbudumbudu (enezimbobo ezimelana nokuhuzuka).
5. Imininingwane Yezobuchwepheshe
Isilinganiso Sokucindezela: Ingcindezi ngokuvamile iphansi ukuya emaphakathi (isb., PN6–I-PN16 / Isigaba 125–Isigaba 150).
Ibanga Lezinga lokushisa:
Ama-elastomer ajwayelekile (isb, i-NR, i-EPDM): -10°C ku90°C (14°F kuya ku-194°F).
Izivalo zokushisa okuphezulu (isb., i-Viton®, i-PTFE): -20°C kuya ku-150°C (-4°F kuya ku-302°F).
Ukuthobela Izindinganiso:
Idizayini: EN593, API 609, MSS SP-67.
I-Flange: ANSI B16.5, ANSI B16.10 DIN EN 1092-1,
Ukuhlolwa: I-API 598, (ukuhlolwa kokuvuza).
6. Izicelo
Amavalvu ebhabhathane aqinile aqinile aqinile aqinile I-D341X-16Qzisetshenziswa kabanzi ku:
Ukuhlinzekwa Kwamanzi Nokuthuthwa Kwendle: Izinhlelo zamanzi zikamasipala, izindawo zokukhuculula indle, namanethiwekhi okunisela.
Amasistimu we-HVAC: Ukulawulwa komoya, amanzi, noma isitimu ekushiseni, ekungeneni komoya, nasekupholiseni umoya.
Imboni Yokudla Neziphuzo: Izicelo zenhlanzeko ezinezimpawu ezithobela i-FDA (isb, i-EPDM enezingubo zebanga lokudla).
Izinqubo Ezivamile Zezimboni: Ukuphatha uketshezi olungagqwali kumakhemikhali, amaphepha, nezitshalo zemithi (okwemidiya epholile kuphela).
Ukwakha Imikhumbi Yasolwandle: Ukulawula ukuvulwa/ukuvalwa kwamanzi olwandle noma izinhlelo ze-ballast (ezinezinto ezingamelani nokugqwala).
7. Imikhawulo kanye Nokucatshangelwa
Imikhawulo Yengcindezi Nezinga Lokushisa: Ayilungele ingcindezi ephezulu (isb, >PN16) noma izinga lokushisa elidlulele (isb., isitimu esingaphezu kuka-150°C).
Izingozi Zokugqwala: Izingxenye zensimbi (isb., imizimba yensimbi ecijile) zingagqwala ezindaweni ezinolaka; thuthukela kunsimbi engagqwali noma izinto ezimboziwe ezimweni ezinzima.
I-Abrasive Media: Izivalo ezithambile zingaguga ngokushesha ngoketshezi olugcwele izinhlayiya; cabangela ama-valve uvemvane ane-hard-seal noma ezinye izigqoko zokuzivikela.
Ukukhetha I-Actuator: Kumavalvu anobubanzi obukhulu noma ukusebenza njalo, sebenzisa ama-actuator e-pneumatic/hydraulic ukuze ugweme ukukhathala okwenziwa ngesandla.
8. Ukufakwa kanye Nokugcinwa
Ukufakwa:
Qinisekisa ukuthi ama-flange aqondile futhi amabhawodi aqiniswa ngokufanayo ukuvikela ukuvuza.
Gwema ukufaka i-valve ngaphansi kokucindezeleka okukhulu kwepayipi.
Ukunakekela:
Hlola njalo uphawu lokuguga noma ukuqhekeka, ikakhulukazi ezinhlelweni zomjikelezo ophezulu.
Gcoba isiqu ne-actuator ngezikhathi ezithile ukuze uqinisekise ukusebenza kahle.
Shintsha uphawu uma ukuvuza kwenzeka; eminye imiklamo ivumela ukushintshwa kwezimpawu ngaphandle kokukhipha i-valve epayipini.
9. Amathiphu Wokukhetha Umhlinzeki Nemikhiqizo
Ukuqinisekiswa Kwezinto Ezibalulekile: Qinisekisa ukuthi ama-seal ahlangabezana namazinga emboni (isb, i-FDA yokudla, i-ATEX yendawo eqhumayo).
Izinketho zokwenza ngokwezifiso: Abanye abahlinzeki bahlinzeka ngemiklamo ephikisana ne-static, izici eziphephile emlilweni, noma ama-coatings akhethekile (isb, i-epoxy, i-PTFE) yezinhlelo zokusebenza ze-niche.
Isiphetho
Amavalvu ebhabhathane aqinile aqinile aqinile aqinileziyisixazululo esingabizi, esithembekile sokulawula ukugeleza kwengcindezi ephansi kuya kwemaphakathi ezinhlelweni ezingabalulekile. Ukuba lula kwazo, ukuvala uphawu okuqinile, kanye nokugcinwa kalula kwazo kuzenza zibe ukukhetha okudumile emanzini, i-HVAC, nezinhlelo zezimboni ezijwayelekile. Ngezindawo ezidinga kakhulu, ukuthuthukela kumiklamo ye-eccentric noma izinto ze-premium kuyanconywa. Hlala uhlola izici zemidiya, izimo zokusebenza, kanye nezidingo zokuhambisana ukuze ukhethe ivalvu efanelekile yezidingo zakho.
Noma iyiphi irabha ehlezi igxileuvemvane valve, njenge-wafer butterfly valve, i-lug butterfly valveI-D7L1X-16Q, i-Y-strainer, i-valve yokuhlola i-wafer,i-valve yesangoI-Z41X-16Qizicelo, ongaxhumana nazoI-valve ye-TWSifekthri, sizokuphendula okokuqala ngqa.
