I-Ductile i-iron iron i-iron i-rating yerabha yerabha yokujonga i-valve engazange ibuye ivelve

I-Ductile i-iron iron i-iron iphindwe kabini i-swing wing ving valve engazange ibuye iveli. Ububanzi bokwakhiwa yi-DN50-DN600. Uxinzelelo oluchanekileyo lubandakanya i-PN10 kunye ne-PN16. Izinto zeValve zetshekhi zikhuphe i-iron, i-ductile, i-WCB, iNdibano yeRubber, intsimbi engenasibala njalo njalo.

I-valve yokutshekisha, i-valve engabuyisi okanye i-valve enye sisixhobo somatshini, esihlala sivumela amanzi (ulwelo okanye igesi) ukuba ihambe kwindawo enye kuphela. Jonga i-valves ziivalve ezimbini ezinamazibuko, okuthetha ukuba zineendawo ezimbini ezivulekileyo emzimbeni, enye ingena kwelinye ingenayo kunye nelinye. Kukho iintlobo ezahlukeneyo zeevali zokujonga ezisetyenziswa kwiintlobo ezahlukeneyo zezicelo. Jonga i-valves zihlala ziyinxalenye yezinto eziqhelekileyo zasekhaya. Nangona zifumaneka kuluhlu olubanzi lwesayizi kunye neendleko, iivalves ezininzi zincinci kakhulu, ezilula, / okanye zixabiso eliphantsi. Jonga i-valvers isebenza ngokuzenzekelayo kwaye uninzi alulawulwa ngumntu okanye naluphi na ulawulo lwangaphandle; Ngokufanelekileyo, uninzi alunalo isibambo se-valve okanye isiqu. Imizimba (igobolondo yangaphandle) yeevalves zetshekhi zenziwa nge-ductile yensimbi okanye i-WCB.
