I-ZDT Model Automatic recirculation control valve
I-ZDT yochungechunge lwe-Automstic recirculation valve iwuhlobo lwedivayisi yokuvikela iphampu. Ivikela ngokuzenzakalelayo iphampu ye-centrifugal lapho umzimba wepompo kwenzeka ukulimala kwe-cavitation noma ukungazinzi (ikakhulukazi ukudlulisa amanzi ashisayo ekusebenzeni komthwalo ophansi). Uma ukugeleza kwepompo sekuphansi kunokugeleza okusethiwe, i-bypass ingavuleka ngokuphelele ukuze kuqinisekiswe ubuncane bephampu yokugeleza edingekayo. Ngisho nokugijima kuvaliwe ngokugcwele, okungukuthi ukugeleza okuyinhloko kunguziro, ukugeleza okuncane nakho kungaphuma ku-bypass.
Uchungechunge lwe-ZDT lunokudlula okukhulu, futhi le valve ifanele ukudlula ngokugeleza okukhulu, umehluko omkhulu wengcindezi ngu-4MPa, ukukhetha okukhethekile kunqunywa ifektri.
• Isakhiwo esilula, ukusebenza okuthembekile nezinzile, okunezingxenye zokunyakaza ezimbalwa.
• Yiba lula ekufakweni, ingafakwa iqonde phezulu noma ivundlile endaweni yokupompa.
• Ukugeleza kwe-Bypass kukhulu, ukugeleza okuphezulu kungu-60% wokugeleza okuyinhloko, i-valve ye-KV ingalungiswa.
• Umehluko omkhulu wengcindezi yokusebenza kwe-bypass ngu-4MPa. Umsebenzi ongabuyisi we-Bypass uyazikhethela.
• Isisetshenziswa esisebenzayo esihlanganisa: amanzi, uwoyela, i-methanol nokunye okuwuketshezi.
• Izinga lokushisa lokusebenza: -196℃ ukuya ku-+130℃.
Uhlobo lomzimba we-valve: i-valve yokusakaza yezindlela ezintathu
Ububanzi bokuzisholo: NPS1"-16" (DN25, 32, 40, 50, 65, 80, 100, 200, 250, 300, 350, 400)
Ingcindezi encane: CL150#-400# (PN16, 25, 40, 64)
Qeda uhlobo lokuxhuma: I-Flange FF, RF, RTJ, BW, SW, njll.
Ngokomehluko wokugeleza okuyinhloko kwe-inductive, ikhoni yokuhlola idiski ye-valve ezenzakalelayo ye-automatic recirculation valve izohamba ngokuzenzakalelayo endaweni ethile. Ngaso leso sikhathi isiqu se-valve ye-valve eyinhloko, dlulisa ukunyakaza kwe-disc ye-valve enkulu ukuze udlule, ngokulawula indawo ye-valve ye-disc, shintsha indawo ye-bypass throttling, ukuze ulawule ukugeleza kwe-bypass. Uma i-disc ye-valve eyinhloko ibuyela esihlalweni se-valve ivaliwe, wonke ageleza abuyele emuva adlule ngokudlula. Lapho i-disc ye-valve eyinhloko ikhuphukela endaweni ephezulu, i-bypass ivalwe ngokugcwele, konke ukugeleza kwepompo ukugeleza ohlelweni lokucubungula. Le valve ibeka imisebenzi emine emzimbeni owodwa.
• Umbono wokugeleza: I-automatic valve recircution main valve disc ingabona ngokuzenzakalelayo ukugeleza okuyinhloko kwesistimu yenqubo, ngaleyo ndlela ngokuvumelana nokugeleza kokunquma indawo yediski ye-valve eyinhloko kanye ne-bypass disc.
• Ukulawula ukujikeleza kabusha: Ivalvu yokujikeleza kabusha okuzenzakalelayo ingakwazi ukuhogela ukusebenza kwephampu evamile edingekayo ukugeleza okuncane kusisetshenziswa sesitoreji ngokudlula, ukuze kulungiswe izici zephampu ye-HQ, ukuze kuqashwe kabusha.
• I-valve yokuhlola: Ivalvu yokujikeleza okuzenzakalelayo nayo inomphumela we-valve wokuhlola, okuvimbela ukugeleza okubuyela emuva koketshezi ukumpompa umzimba. Umsebenzi ongabuyisi we-Bypass uyazikhethela.
• Usayizi wokudlula okhethekile ungenziwa ngokwezifiso. Izinga lokugeleza elikhulu lokudlula lingaphansi kwevelu enkulu ye-Kv.
