1. Incazelo Lesisekelo Nesakhiwo
Ivalve lethambile yekuvala lene flange lesemkhatsini (lephindze yatiwe ngekutsi "ivalve ye butterfly lesemkhatsini") yivalve lejikeletako lejikako leyentelwe kuvula/kuvala noma kulawula kugeleta kwe throttling emaphayiphini. Timphawu tayo letiyinhloko tifaka ekhatsi:
Concentric Design: Sicu sevalve, idiski, kanye nesihlalo kuhambisana ne-axis lefanako lesemkhatsini, kwenta sakhiwo lesilula nalesincane.
Indlela Yekuvala Lethambile: Sivalo se-elastomeric lesigucugucukako (sib., iraba, i-EPDM, i-NBR) sihlanganiswa emtimbeni wevalve noma esihlalweni, kuniketa sivalo lesicinile kuvikela kuvuza.
Flanged Ends: Le valve ifakwe kuxhumana kwe flanged, kuvumela kufakwa lokulula kumaphayiphi lahambisana nemazinga lafana ne ANSI, DIN, noma JIS.
2.Tincenye letibalulekile
3. Umtsetfo Wekusebenta
Sikhundla Lesivulekile: Le disc ijikeleta 90° kuhambisana nendlela yekugeleta, kunciphisa kwehla kwemfutfo kanye nekuvumela kugeleta lokugcwele.
Sikhundla Levaliwe: Le disc ijikeleta emuva kucindzetela kulesivalo lesitsambile, kwenta kuvalwa lokucinile. Le design ye concentric incike ekugucukeni kwe elastic kwesivalo kwentela kufeza kuvala, kwenta kutsi kusebente kakhulu ekusebentiseni lokuphansi.
4. Timphawu Letimcoka Netinzuzo .
Kuvala Lokucinile: Tivalo letitsambile tiniketa kumela lokuhle kakhulu kwekuvuza, kuvame kuhlangabetana nemazinga lacinile emabhubhu (sib., ANSI B16.104 Lizinga VI, ISO 15848-1).
Kusebenta Kwe-Torque Lephansi: Umklamo losemkhatsini kanye nekuvala lokugucugucukako kunciphisa kukhuhlana, kuvumela kusebenta ngesandla lokulula noma kusetjentiswa nge-actuators lelula.
Incane futsi Ilula: Uma icatsaniswa nemavalvu esango noma emhlaba, emavalvu e-concentric butterfly mancane futsi kulula kuwafaka etindzaweni letincane.
Tindleko-Letisebentako: Sakhiwo lesilula kanye nekusetjentiswa kwetintfo letiphansi kwenta kutsi tikhone kutsengeka ngetidzingo tekulawula kugeleta letisisekelo.
Kuhambisana Kwetindzaba Letihlukahlukene: Kulungele emanti, umoya, oyili, tintfo letingagcobi, kanye netindzaba letinetinhlavu (letinetintfo letimelana nekuguga).
5. Tincazelo tebuchwepheshe
Silinganiso Sekucindzeteleka: Ngalokuvamile kucindzeteleka lokuphansi kuya kulokusemkhatsini (sib., PN6).–PN16 / Likilasi 125–Likilasi 150).
Lizinga lekushisa:
Ema-elastomer lajwayelekile (sib., NR, EPDM): -10°C kuya ku 90°C (14°F kuya ku 194°F).
Timphawu letinekushisa lokusezingeni leliphakeme (sib., Viton®, PTFE): -20°C kuya ku 150°C (-4°F kuya ku 302°F).
Kulandzela Emazinga:
Umklamo: SIVI 593, i-API 609, i-MSS SP-67.
I-Flange: I-ANSI B16.5, i-ANSI B16.10 I-EN 1092-1,
Kuhlolwa: API 598, (kuhlolwa kwekuvuza).
6. Ticelo
Emavalvu evivane lane-flanges lane-flanges lethambile D341X-16Qtisetjentiswa kakhulu ku:
Kuphakelwa Kwemanti Nekukhipha Emanti: Tinhlelo temanti tamasipala, tikhungo tekuhlanta imfucuza, kanye nemanethiwekhi ekunisela.
Tinhlelo te-HVAC: Kulawula umoya, emanti, nobe umfutfo ekushiseni, ekungeniseni umoya, kanye nasekuphefumuleni.
Imboni Yekudla Nekunatsa: Ticelo tekuhlanteka letinetimphawu letihambisana ne FDA (sib., iEPDM lenetintfo tekugcoka letisesigabeni sekudla).
Tinchubo Tetimboni Letivamile: Kuphatfwa kwemanti langagcobi etitjalweni temakhemikhali, emaphepha, kanye netemitsi (yetindzaba letincane kuphela).
Elwandle kanye nekwakha imikhumbi: Kulawula kuvula/kuvala emantini elwandle noma etinhlelo te ballast (ngetintfo letimelana nekugcola).
7. Imikhawulo kanye netintfo leticatshangelwako
Imikhawulo Yekucindzeteleka Nekushisa: Akukafaneli kusetjentiswa kwekucindzeteleka lokusetulu (sib., >PN16) noma kusetjentiswa kwekushisa lokukhulu (sib., umfutfo longetulu kwa 150°C).
Tingoti Tekugcola: Tincenye tensimbi (sib., imitimba yensimbi lephosiwe) tingagcola etindzaweni letinelulaka; ngcono ibe yinsimbi lengagucuki noma tintfo letigcotjiwe tetimo letilukhuni.
Abrasive Media: Timphawu letitfobekile tingagcoka ngekushesha ngetintfo letimanti letigcwele tinhlayiya; cabanga ngemavalvu e-butterfly lacinile noma tintfo letengetiwe letivikelako.
Kukhetsa I-Actuator: Kumavalvu lamakhulu noma kusebenta njalo, sebentisa ema-actuator emoya/e-hydraulic kugwema kudzinwa ngesandla.
8. Kufakwa kanye nekunakekelwa
Kufakwa:
Ciniseka kutsi emaflanges ahambisana futsi emabhawudi aciniswa ngendlela lefanako kuvikela kuvuta.
Gwema kufaka i-valve ngaphansi kwekucindzeteleka lokukhulu kwemaphayiphi.
Kondla:
Hlola njalo le seal kutsi igcokile noma iyadzabuka, ikakhulukati ekusebentiseni lokusetulu kwemjikeleto.
Gcobisa sicu kanye ne-actuator ngetikhatsi letitsite kucinisekisa kusebenta kahle.
Faka esikhundleni sesivalo uma kwenteka kuvuza; letinye tindlela tivumela kushintjwa kwesivalo ngaphandle kwekususa ivalve kusuka ephayiphini.
9. Tiluleko Tekukhetsa Umphakeli Nemkhicito
Sitifiketi Setintfo: Cinisekisa kutsi timphawu tihlangabetana nemazinga emboni (sib., iFDA yekudla, iATEX yetindzawo letiqhumako).
Tintfo Letingentiwa Ngendlela Lefanele: Labanye batsengisi baniketa imiklamo lelwa ne-static, timphawu letiphephile emlilweni, noma tintfo letikhetsekile (sib., i-epoxy, i-PTFE) yekusebentisa i-niche.
Siphetfo
Emavalvu evivane lane-flanges lane-flanges lethambilekukhona sisombululo lesingabizi, lesetsembekile sekulawula kugeleta kwemfutfo lophansi kuya kulomkhatsini etincenyeni letingakabaluleki. Kuba lula kwawo, kuvala lokucinile, kanye nekunakekelwa kalula kwenta kutsi kube yintfo lethandwako emantini, iHVAC, kanye netinhlelo tetimboni jikelele. Kute utfole tindzawo letifuna kakhulu, kutfutfukisa kuya kumiklamo ye eccentric noma tintfo te premium kuyanconywa. Ngaso sonkhe sikhatsi hlola timphahla tetindzaba, timo tekusebenta, kanye netidzingo tekuhambisana kute ukhetse ivalve lefanele yetidzingo takho.
Noma nguyiphi irabha lehleti i-concentricivalvu yevivane, njengevalve yeluvivane ye-wafer, ivalve yeluvivane ye-lugD7L1X-16Q, Y-sisefa, ivalvu yekuhlola i-wafer,Ivalvu yesangoZ41X-16Qimfuno, ungatsintsana naIvalvi ye-TWSimboni, sitawuphendvula wena kwekucala.
