Qhib-qhib / tsaus nti nodular cam khwb cia hlau flange rooj vag valve yog ib hom nodular cam khwb cia hlau cov khoom ua los ntawm flange rooj vag valve, muaj zog siab, hnav tsis kam thiab zoo seismic kev ua tau zoo. Hom valve no tau siv dav hauv ntau yam kev tsim kho tshuab, roj av, tshuaj lom neeg kev lag luam, kev kho dej thiab lwm yam kev lag luam kom ua tiav kev txiav tawm, kev ncig thiab kev tswj hwm ntawm cov raj xa dej.
Qhib pas nrig / tsaus nti ductile hlau flange rooj vag li qub xws li DN250, DN300, DN400, DN500, DN600, DN700, DN800 thiab DN900 thiab lwm qhov ntau thiab tsawg kom tau raws li qhov xav tau kev sib txuas ntawm cov kav dej sib txawv. Kev sib txuas hom ntawm lub valve yog flange kev twb kev txuas, uas yog ib qho yooj yim rau nruab thiab tswj.
Qhib pas nrig thiab cov pas nrig tsaus yog ob txoj haujlwm ua haujlwm ntawm nodular cam khwb cia hlau flange rooj vag valve. Kev qhib pas nrig txhais tau hais tias qhov qhib thiab kaw ntawm lub valve ncaj qha ua rau ntawm lub valve qia los ntawm tes log, thiab kev ua haujlwm yog qhov yooj yim thiab yooj yim. Kev ua haujlwm ntawm tus pas nrig zais yog hloov pauv cov lus tsa suab ntawm lub log los ntawm lub valve qia txiv ntoo rau hauv txoj kab ncaj nraim ntawm lub qia valve, kom lub valve qhib lossis kaw. Kev ua haujlwm ntawm cov pas nrig tsaus yog qhov ruaj khov dua li kev ua haujlwm qhib pas nrig, haum rau kev kub siab, txoj kab uas hla loj.
Feem ntau, qhib pas nrig / tsaus nti ductile hlau flange rooj vag valve nrog nws cov khoom zoo heev thiab ntau yam kev qhia tshwj xeeb, dav siv hauv txhua yam haujlwm, rau kev nyab xeeb thiab txhim khu kev lag luam ntawm cov raj xa dej muab kev lav zoo.
