Valovu yagulugufe wapawirimawu oyamba, ntchito, zinthu, ubwino ndi kuipa, kukonza ndi kukonza.
Valavu yagulugufe ya Double eccentric ndi valavu yowongolera yomwe imagwiritsidwa ntchito nthawi zambiri, yoyenera kuwongolera mitundu yosiyanasiyana yamadzimadzi osawononga kapena ofooka. Mapangidwe a valve ndi apadera, kupyolera mu mawonekedwe awiri a eccentric, kotero kuti valavu ndi theka lotseguka, mbale ya valve ndi mphete yosindikizira zisagwirizane, kupyolera mumadzimadzi, kuchepetsa kuvala kwa chisindikizo, kuwonjezera moyo wautumiki wa valve. , Komanso, chifukwa valavu mbale axis apatuka pakati valavu, kuonjezera kunyamula mphamvu ya mbale valavu, patsogolo chitetezo ntchito.
Valavu imagwiritsidwa ntchito makamaka mu petrochemical, mphamvu yamagetsi, zitsulo, chithandizo chamadzi ndi madera ena, angagwiritsidwe ntchito poyendetsa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake. Malinga ndi momwe ntchito ikugwirira ntchito komanso mawonekedwe a sing'anga, zida zosiyanasiyana zimatha kusankhidwa, monga chitsulo cha carbon, chitsulo chosapanga dzimbiri, chitsulo cha alloy, mkuwa ndi zina zotero.
Ubwino wa double eccentric butterfly valves ndikuti umakhala ndi magwiridwe antchito abwino, kutsegula ndi kutseka mwachangu komanso kuyankha tcheru, kusindikiza kwabwino, kumatha kupirira kusiyanasiyana kosiyanasiyana ndi kukhudzidwa kwamadzimadzi, kapangidwe kosavuta, kukhazikitsa kosavuta ndi kukonza. Choyipa ndichakuti chifukwa cha kapangidwe kake, pali ngodya zakufa komanso kukana kwanuko mkati mwa valavu, zomwe zimakhudza kuyenda bwino kwamadzimadzi.
Kuti muwonjezere moyo wautumiki wa valavu yagulugufe wapawiri, m'pofunika kulabadira zotsatirazi:
1. Nthawi zonse muzitsuka ndi kuyeretsa valavu, fufuzani kuti mphete yosindikizira ndi mbale ya valve yavala, ndipo ikani m'malo mwake ngati yavala.
2. Pogwiritsa ntchito, pewani kukhudzidwa ndi kugwedezeka kwa valve, pewani kutenthedwa ntchito yowotcherera kapena ntchito zina zotentha kwambiri pafupi ndi valve, kuti valavu isawonongeke kapena kuwonongeka.
3. Pewani kuchuluka kwa zinyalala mkati mwa vavu ndikuyeretsa payipi mu nthawi.
4. Yang'anani ndi kusunga valavu nthawi zonse, ndipo yesetsani kuthana ndi vutoli panthawi yake kuti musasokoneze kagwiritsidwe ntchito ka valve.
Mukafuna kusankha valavu yagulugufe iwiri, muyenera kusankha wopanga chovomerezeka, monga valavu ya likv. Wopangayo ali ndi zaka zambiri zakupanga ndi mphamvu zamakono, khalidwe la mankhwala latsimikiziridwa ndi mabungwe ovomerezeka, komanso kupereka chithandizo chapamwamba pambuyo pa malonda ndi chithandizo chaumisiri, chingapereke kwa ogwiritsa ntchito zinthu zodalirika ndi ntchito.
