Chiwafer dual plate check valvealimwi ninzila yakukwabilila iilaa nzila yakuzungaanya, pesi ilijisi disiki zyobile alimwi ilajala akaambo kakubelesegwa kwasipulo. Disiki ilasunkwa kujalulwa amaanzi azwa ansi kuya mujulu, vvalavu ilijisi bupange buuba, chikwabilizyo chibikkidwe aakati kama flange obile, mpawo bupati buniini abulemu buniini.
Chiwafer dual plate check valveilijisi madiski obile aajisi nsinga zya D-shaped aabikkidwe aacibulo cijisi nsinga kuzabuka bbola lya valve. Bupange oobu bufwiinsya musinzo ooyo akati ka nguzu zyakukwela zya disiki nzyeenda. Ooku kuyaka akwalo kulacesya kulema kwa disiki a 50% kweelanisigwa a disiki lyomwe lizungaana a check valve lyabupati bweelene. Twalumba akaambo kamukuli wa spring, vvalavu ilafwambaana kuchita kuti maanzi ajokele.
I wafer dual plate check valve's double lobe lightweight construction ipa kuti chibbula chikwabilile akubeleka kabotu.
Ikujatikizigwa kwa janza lilamfwu lya bbatterfly yobilevvalavu yakulangailapa kuti disiki ijaluke akujala kakunyina kufwusa chibbula, mpawo sipring ilabeleka alikke kujala disiki (DN150 kuya mujulu).
Ijanza lyakugwasilizya lijisi ntambo zya bbatterfly iijisi zibeela zyobilevvalavu yakulangakucesya kuzwangana akucesya nkomo yamaanzi kuti yagwisyigwa kwiinda mu disiki limbi (mugoti mupati).
Kweezyanisya azyachiindimavalvu aakulanga,wafer dual plate check valvekuyaka kanjikanji nkuyumu, nkuuba, nkuniini, kubeleka obotu, alimwi takuduli pe. Eeyi vvalavu ilazuzikizya zyeelelo zya API 594, kuzibeela zyiingi, bupati bwa vvalavu eeyi buli buyo a 1/4 ya vvalavu iizyibidwe, mpawo kulema kwayo mbu 15%~20% ya vvalavu iizyibidwe, aboobo iladula kwiinda vvalavu ya swing check. Alimwi nchuubauba kubikka aakati kama gasketi aamapayipi. Nkaambo kakuti nchuubauba kweendelezya mpawo chiyanda buyo bbolati lyomwe lyakujata, alimwi chikwabilila zibeela muchiindi chakubikka, mpawo chikwabilila mali yakubikka antoomwe amali yakubambulula abuzuba.
Ivalvu yakukwabilila iijisi zibeela zyobile alimwi ilijisi zibeela zyaalubazu zyakuyaka zipa kuti ivalvu eeyi ibe vvalavu iibeleka obotu iitakwe ntenda. Eezyi zintu zibikkilizya kujalula kutakwe kusalala, kuyaka kwachipimo chamavwili manji, antoomwe anzila zyakugwasyilizya madiski. Zimwi zyazintu eezyi tazikonzyi kujanwa amavalvu aakulanga. I wafer dual plate check valve ilakonzya kuchitwa ama lugs, double flanges antoomwe amubili uuyungizyidwe.
Chakusanguna, nzila yakujula akujala
Bupange bwamadiski obile bujisi madiski obile aajisi ntalisyo (ma semi-disc) aaangidwe kuzwa ku pini iijisi nkomo iiliimvwi akati. Aawo maanzi naatalika kweenda, disiki ilajaluka anguzu (F) zibeleka aakati kabusena bwakujala. Nguzu zyakugwasyilizya zyakukwabilila (FS) zilabikkwa kunze lyaakati-kati kabusyu bwadisiki, akupa kuti muyanda wadisiki ujaluke kusaanguna. Eezi zilatantamuka kuzwangana aabusena bwakujala ooko kuchitika aawo disiki nolijalulwa mumavalvu aakaindi, akulesya kubola akutyoka kwazibeela.
Eelyo kweenda kwamaanzi nokwaceya, ntalisyo ya torsion ilachita mulimu, akupa kuti disiki ijale akuswena afwaafwi achibbula chamubili, akucheesya musinzo wakujala. Eelyo maanzi naakali kweenda kuya musule, disiki lilaunka asyoonto-asyoonto afwaafwi achuuno chamubili, mpawo nsandulo ya valve ilafwambaana loko, ikucheesya nguzu zya nkomo yamaanzi akuchita kuti kube kubeleka kakunyina kutyompokelwa.
Notujala, kubeleka kwanguzu zya spring kupa kuti atala lya disiki lijale kusaanguna, ikukwabilila kuluma akuzwangana kumuyanda wa disiki, kuchitila kuti vvalavu ikonzye kubamba kusyomeka kwachikwabilizyo kwachiindi chilamfu.
2. Bupange bwakuliimya
Bupange bwachisimpi (DN150 kuya mujulu) bupa kuti kube nguzu zyiingi kudisiki lyomwe lyomwe mpawo disiki lilajala lwini-lwini mbuli mbokuchincha kweenda kwamaanzi. Kusola kwakatondezya kuti eechi chintu chakapa kuti buumi bwamavalvu buyungizigwe a 25% mpawo akucheya kwa 50% kwa nkomo yamaanzi.
Cibeela chimwi achimwi cha disiki yobile chili amasipulo aayo aapa manguzu aakujala aalikke mpawo abikkwa mumbali aa 140° (chitondeezyo 3) muciindi cha 350° yasipulo yabuzubaa buzuba iijisi mabbaketi obile.
3. Bupange bwakuliimya kwa disiki
Bupange bwakujatikizigwa butakweendelani bulagwisya kuzwangana a 66%, eezyo zipa kuti vvalavu ibeleke kabotu. Ijanza lyakugwasyilizya lilabikkwa kuzwa kunze kuchitila kuti ntambo yakujulu ikonzye kugwasyilizyigwa aajanza lyaansi muchiindi cha valve noibeleka. Eezi zipa kuti ma disc oonse obile achite chakufwambaana akujala muchiindi chomwe, mpawo akuchita obotu loko.
