Iithegi zeMveliso

Uchungechunge lwe-ZDT lwe-Automstic recirculation valve luhlobo lwesixhobo sokukhusela impompo. Ikhusela ngokuzenzekelayo ipompo ye-centrifugal xa umzimba wempompo usenzeka umonakalo we-cavitation okanye ukungazinzi (ingakumbi ukuhambisa amanzi atshisayo ekusebenzeni komthwalo ophantsi). Nje ukuba umpompozo wempompo uphantsi kunomqukuqelo osele ubekiwe, i-bypass inokuvuleka ngokupheleleyo ukuqinisekisa ubuncinci impompo yokuqukuqela efunekayo. Nokuba ibaleka ivalwe ngokupheleleyo, oko kukuthi ukuhamba okungundoqo ngu-zero, ukuhamba kancinci kunokukhutshwa kwi-bypass.

Uchungechunge lwe-ZDT lune-bypass enkulu, kwaye le valve ifanelekile ukudlula ngokuhamba okukhulu, ukuhlukana koxinzelelo oluphezulu yi-4MPa, ukhetho oluthile lunqunywe yifektri.

Iimpawu

• Ulwakhiwo olulula, umsebenzi othembekileyo nozinzileyo, onamalungu ambalwa entshukumo.
• Yiba lula ukufakela, inokufakwa ngokuthe nkqo okanye ngokuthe tye kwi-outlet yempompo.
• Ukuhamba kwe-Bypass kukhulu, ukuhamba okuphezulu yi-60% yokuhamba okuphambili, i-valve ye-KV inokulungiswa.
• Owona mahluko woxinzelelo oluphezulu lokugqitha yi-4MPa. Umsebenzi wokugqitha ongabuyisiyo awunyanzelekanga.
• Umthombo osebenzayo oquka: amanzi, i-oyile, i-methanol kunye nolunye ulwelo.
• Ubushushu bokusebenza: -196℃ ukuya +130℃.

Ububanzi kunye noluhlu loxinzelelo

Uhlobo lomzimba wevalvu: ivelufa yeendlela ezintathu

Idayamitha yokulinganisa: NPS1"-16" (DN25, 32, 40, 50, 65, 80, 100, 200, 250, 300, 350, 400)

Uxinzelelo lwegama: CL150#-400# (PN16, 25, 40, 64)

Uhlobo lokuphela koxhulumaniso: Flange FF, RF, RTJ, BW, SW, njl.

Umgaqo wokusebenza

Ngokomahluko we-inductive main flow, i-disc ye-valve engundoqo yokukhangela i-cone yevalve yokubuyisela ngokuzenzekelayo iya kuhamba ngokuzenzekelayo kwindawo ethile. Kwangaxeshanye idiskhi engundoqo yediskhi yevalve ye-bypass stem, ukuhambisa intshukumo ye-disc yevalve engundoqo ukuya ku-bypass, ngokulawula indawo ye-valve ye-disc ye-bypass, ukuguqula indawo ye-bypass throttling, ukuze kulawulwe ukuhamba kwe-bypass. Xa idiskhi yevalve engundoqo ibuyela kwisitulo sevalvu ivaliwe, zonke ziqukuqela umva ngokudlula. Xa i-disc ye-valve engundoqo iphakama kwindawo ephezulu, i-bypass ivalwe ngokupheleleyo, konke ukuhamba kwempompo ukuya kwinkqubo yenkqubo. Le valve ibeka imisebenzi emine kumzimba omnye.

• Umbono wokuqukuqela: Idiskhi yevalvu ejikelezayo ezenzekelayo inokuzibona ngokuzenzekelayo ukuhamba okungundoqo kwenkqubo yenkqubo, ngoko ke ngokokuhamba ukugqiba indawo yediski yevalve engundoqo kunye nediski yokudlula.
• Ulawulo lokujikeleziswa kwakhona: Ivalve ejikelezayo ezenzekelayo inokuphefumlela impompo yokusebenza okuqhelekileyo okufunekayo ukuhamba kancinci kwisixhobo sogcino ngokudlula, ukuze kuhlengahlengiswe iimpawu zempompo ye-HQ, ukuqonda ukurisayikilishwa.
• Ivalve yokujonga: Ivalve ephinda ijikelezwe ngokuzenzekelayo nayo ineempembelelo zevalvu yokutshekisha, inqanda ukubuya umva kolwelo ukumpompa umzimba. Umsebenzi wokugqitha ongabuyisiyo awunyanzelekanga.
• Ubungakanani obukhethekileyo bokudlula bungenziwa ngokwezifiso. Obona bungakanani bokuhamba komyinge we-bypass ixhomekeke kubukhulu bexabiso le-Kv.
