1. Incazelo Eyisisekelo kanye 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:
Umklamo Oqondile: Isiqu se-valve, idiski, kanye nesihlalo kuqondiswe ku-axis efanayo ephakathi, okudala isakhiwo esilula nesincane.
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 Ezigobile: Ivalvu ifakwe ukuxhumeka okugobile, okuvumela ukufakwa okulula kumapayipi okuhambisana nezindinganiso ezifana ne-ANSI, DIN, noma i-JIS.
2.Izingxenye Eziyinhloko
3. Isimiso Sokusebenza
Indawo Evulekile: Idiski ijikeleza ama-90° ukuze kuhambisane nesiqondiso sokugeleza, kuncishiswe ukwehla kwengcindezi futhi kuvunyelwe ukugeleza okugcwele.
Indawo Evaliwe: Idiski iphenduka emuva ukuze icindezele uphawu oluthambile, okwenza kube nokuvaleka okuqinile. Umklamo oqondile uthembele ekuguqulweni kwe-elastic kophawu ukuze kufezwe ukuvalwa, okwenza lusebenze kahle kakhulu ekusetshenzisweni kokucindezela okuphansi.
4. Izici Eziyinhloko Nezinzuzo
Ukuvala Okuqinile: Izivalo ezithambile zinikeza ukumelana okuhle kakhulu nokuvuza, ngokuvamile zihlangabezana nezindinganiso zokuvala amabhamuza (isb., i-ANSI B16.104 Class VI, ISO 15848-1).
Ukusebenza kwe-Torque Ephansi: Umklamo oqondile kanye nesivalo esiguquguqukayo kunciphisa ukungqubuzana, okuvumela ukusebenza ngesandla okulula noma ukusetshenziswa ngama-actuator alula.
Incane Futhi Ilula: Uma kuqhathaniswa namavalvu esango noma eglobhu, amavalvu ebhabhathane aqinile mancane futhi kulula ukuwafaka ezindaweni ezilinganiselwe.
Izindleko Ezingabizi: Isakhiwo esilula kanye nokusetshenziswa kwezinto eziphansi kwenza kube lula ukufeza izidingo eziyisisekelo zokulawula ukugeleza kwamanzi.
Ukuhambisana Kwemidiya Ehlukahlukene: Kufanelekela amanzi, umoya, uwoyela, uketshezi olungaboli, kanye nemidiya ehlanganisiwe (enezimbozo ezingagugi).
5. Imininingwane Yobuchwepheshe
Isilinganiso Sokucindezela: Ingcindezi evame ukuba phansi kuya emaphakathi (isb., i-PN6–I-PN16 / Isigaba 125–Isigaba 150).
Ibanga Lokushisa:
Ama-elastomer ajwayelekile (isb., i-NR, i-EPDM): -10°C kuya ku-90°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:
Umklamo: 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 D341X-16Qzisetshenziswa kabanzi ku:
Ukuhlinzekwa Kwamanzi Nokugeleza Kwamanzi: Izinhlelo zamanzi zikamasipala, izikhungo zokuhlanza indle, kanye namanethiwekhi okunisela.
Izinhlelo ze-HVAC: Ukulawulwa komoya, amanzi, noma umusi ekushiseni, ekuphefumuleni, kanye nasekupholiseni umoya.
Imboni Yokudla Neziphuzo: Ukusetshenziswa kwenhlanzeko okunezimpawu ezihambisana ne-FDA (isb., i-EPDM enezimbozo zokudla).
Izinqubo Ezijwayelekile Zezimboni: Ukuphathwa koketshezi olungaboli ezitshalweni zamakhemikhali, zephepha, nezemithi (ngezinto ezincane kuphela).
Ukwakha Imikhumbi Yasolwandle: Ukulawula ukuvulwa/ukuvalwa kwamanzi olwandle noma izinhlelo ze-ballast (ezinezinto ezingamelani nokugqwala).
7. Imikhawulo kanye nokucatshangelwa
Imikhawulo Yokucindezela Nokushisa: Ayifanele ukusetshenziswa kokucindezela okuphezulu (isb., >PN16) noma ukusetshenziswa kokushisa okweqile (isb., umusi ongaphezu kuka-150)°C).
Izingozi Zokugqwala: Izingxenye zensimbi (isb., imizimba yensimbi ephonswe) zingagqwala ezindaweni ezinolaka; thuthukela ensimbi engagqwali noma ezintweni ezimboziwe ukuze zisetshenziswe ezimweni ezinzima.
I-Abrasive Media: Izivalo ezithambile zingaguga ngokushesha ngoketshezi olugcwele izinhlayiya; cabanga ngamavalvu ebhabhathane aqinile noma ezinye izembozo zokuvikela.
Ukukhethwa kwe-Actuator: Kuma-valve amakhulu noma ukusebenza njalo, sebenzisa ama-actuator omoya/ama-hydraulic ukuze ugweme ukukhathala ngesandla.
8. Ukufakwa Nokunakekelwa
Ukufakwa:
Qinisekisa ukuthi ama-flange aqondile futhi amabhawodi aqiniswe ngokulinganayo ukuze kuvinjelwe ukuvuza.
Gwema ukufaka ivalvu ngaphansi kokucindezeleka okukhulu kwepayipi.
Ukugcinwa:
Hlola njalo isivalo ukuthi asigugi noma siyaqhekeka, ikakhulukazi ezindaweni ezisetshenziswa kakhulu.
Gcoba isiqu kanye ne-actuator ngezikhathi ezithile ukuqinisekisa ukusebenza kahle.
Shintsha uphawu uma kuvela ukuvuza; eminye imiklamo ivumela ukushintshwa kophawu ngaphandle kokususa ivalvu epayipini.
9Amathiphu Okukhetha Umhlinzeki Nomkhiqizo
Isitifiketi Sezinto Ezisetshenziswayo: Qinisekisa ukuthi izisimbozo ziyahlangabezana nezindinganiso zomkhakha (isib., i-FDA yokudla, i-ATEX yezindawo eziqhumayo).
Izinketho Zokwenza Ngokwezifiso: Abanye abahlinzeki banikeza imiklamo elwa nokungaguquguquki, izici ezingashisi umlilo, noma izembozo ezikhethekile (isb., i-epoxy, i-PTFE) zezinhlelo zokusebenza ezikhethekile.
Isiphetho
Amavalvu ebhabhathane aqinile aqinile aqinile aqinileziyisisombululo esingabizi kakhulu nesithembekile sokulawula ukugeleza komfutho okuphansi kuya kokuphakathi ezinhlelweni ezingabalulekile. Ukulula kwazo, ukuvala ngokuqinile, kanye nokulula kokugcinwa kwazo kuzenza zibe ukukhetha okuthandwayo emanzini, kuma-HVAC, kanye nezinhlelo zezimboni ezijwayelekile. Ukuze uthole izindawo ezidinga kakhulu, kunconywa ukuthuthukisa imiklamo engavamile noma izinto zekhwalithi ephezulu. Hlola njalo izakhiwo zemidiya, izimo zokusebenza, kanye nezidingo zokuthobela imithetho ukuze ukhethe i-valve efanele izidingo zakho.
Noma iyiphi irabha ehlezi igxileivalvu yebhabhathane, njenge-valve yebhabhathane ye-wafer, i-valve yebhabhathane ye-lugD7L1X-16Q, Isihluzo se-Y, ivalvu yokuhlola i-wafer,ivalvu yesangoI-Z41X-16Qizidingo, ungaxhumana noI-valve ye-TWSifektri, sizokuphendula okokuqala.
