I-ZDM Series okuzenzakalelayo yokulawula kabusha i-valve
ZDM uchungechunge okuzenzakalelayo recirculation valve uhlobo lwedivayisi ukuvikelwa futha. Ivikela othomathikhi ipompo ye-centrifugal lapho umzimba wepompo uvela ngomonakalo we-cavitation ongazinzile (ikakhulukazi ohambisa amanzi ashisayo ngokusebenza okuphansi). Lapho ukugeleza kwepompo sekuphansi kunokugeleza okuhleliwe, ukudlula kungavuleka ngokuphelele ukuqinisekisa ukuthi iphampu yokugeleza edingekayo ubuncane. Noma kusebenza kuvalwe ngokuphelele, okungukuthi ukugeleza okusebenzayo kuyiziro, ukugeleza okuncane nakho kungadlula ngokudlula kokuphindaphinda okuzenzakalelayo. Ingcindezi yehliswe nge-multistage bypass ingcindezi yokunciphisa i-valve.
Uchungechunge lwe-ZDM lufanele ukudlula ngokuhlukaniswa kwengcindezi ephezulu, umehluko omkhulu wokucindezela ngu-30MPa, futhi ukukhetha okuthile kunqunywa yifektri. Uhlobo lwe-multistage decompression type M type bypass lungaqeda umsindo owenziwe ngejubane lokugeleza okuphakathi, ukuvimbela ukonakala kokuguguleka kwe-cavitation nokugoqa izingxenye ze-valve.
• Vimbela ukudlula ngokweqile kwe-cavitation multistage decompression, ukunciphisa ijubane, elungele izimo ezinengcindezi ephezulu.
Umzimba we-valve owakhiwe, noma ungakhetha i-carbon steel noma i-stainless steel material, njll.
• Umsebenzi odlula ngokungabuyisi ojwayelekile, umehluko omkhulu wokusebenza kwengcindezi yi-30MPa.
• Ibanga lengcindezi kusuka ku-PN16 kuye ku-PN420, ubukhulu kusuka ku-DN2 kuye ku-DN500.
• Ungakhetha umsebenzi wokudlula owenziwa ngesandla, osetshenziswe ngephutha.
Uhlobo lomzimba we-Valve: I-valve enezindlela ezintathu
Ububanzi bokuqokwa: NPS1 "-20" (DN25, 32, 40, 50, 65, 80, 100, 200, 250, 300, 350, 400, 450, 500)
Ingcindezi yegama: CL150 # -2500 # (PN16, 25, 40, 64, 100, 160, 250, 420)
Qeda uhlobo lokuxhuma: i-Flange, i-FF, i-RF, i-RTJ, i-BW, i-SW njll.
Ngokuya ngokwehluka kokugeleza okuyinhloko, i-valve eyinhloko yediski yokuhlola ye-valve ezenzakalelayo yokubuyela emuva izohamba ngokuzenzakalela iye endaweni ethile. Ngasikhathi sinye i-valve enkulu yedrayivu idlula isiqu se-valve, dlulisa ukuhamba kwediski enkulu ye-valve ukudlula, ngokulawula indawo yediski ye-valve, shintsha indawo yokudlula, ukuze ulawule ukugeleza kokudlula. Lapho idiski enkulu ye-valve ibuyela esihlalweni se-valve ivaliwe, konke ukugeleza kubuyela emuva ngokudlula. Lapho i-valve enkulu disc ikhuphukela endaweni ephezulu, ukudlula kuvaliwe ngokuphelele, konke ukugeleza kokugeleza kwepompo kucubungula uhlelo. Le valve ibeka imisebenzi emine emzimbeni owodwa.
• Umbono wokugeleza: I-disc disc ye-valve eyinhloko yokubona okuzenzakalelayo ingabona ngokuzenzakalela ukugeleza okuyisisekelo kohlelo lwenqubo, ngaleyo ndlela ngokuya kokugeleza ukuthola indawo yediski enkulu ye-valve nokudlula idiski.
• Ukulawulwa kwe-recirculation: I-valve yokuphindisela okuzenzakalelayo ingadonsa futha ukusebenza okujwayelekile okudingekayo ukugeleza okuncane okungena kudivayisi yokugcina ngokudlula, ukuze kulungiswe iphampu ye-HQ charateristics, ukubona kabusha.
• Ukwehliswa kwengcindezi ye-Bypass multistage: uhlelo lokulawula ukudlula lunganciphisa okuphakathi kokubuyela emuva kusuka kupayipi elinengcindezi ephezulu kuya ekubuyeleni emuva okufanele kudivayisi yokugcina ingcindezi ephansi enomsindo omncane ukugqoka okuncane.
• Hlola: I-valve yokuphindaphinda okuzenzakalelayo nayo inomphumela we-valve yokuhlola, ukuvimbela ukubuyela emuva kuketshezi ukupompa umzimba. Umsebenzi we-Bypass non-return ujwayelekile.
• Usayizi okhethekile wokudlula ungenziwa ngezifiso. Izinga lokugeleza okukhulu lingaphansi kwenani le-max Kv.
