Mfundo yogwiritsira ntchito katatu eccentric metal hard seal butterfly valve:
Kwa katatu eccentric zitsulo zosindikiza agulugufe mavavu, kuwonjezera pa eccentricity awiri a tsinde valavu ndi mbale valavu, kusindikiza pamwamba pa mbale valavu ndi mpando valavu ali mu mawonekedwe a oblique truncated kolona (ichi ndi eccentricity wachitatu wa chotchedwa katatu eccentricity).Vavu ikatsekedwa, mbale ya valve imakankhidwira kutsogolo chifukwa cha eccentricity.Palibe kukangana pakati pa mbale ya valve ndi mpando wa valve panthawi yotseka.Chovala cha valve chimakanizidwa mwachindunji pampando wa valve, motero kuonetsetsa moyo wautumiki wa valve;kuonjezera apo, chifukwa cha valavu iyi mphete yosindikizira (kaya imayikidwa pampando wa valve kapena mbale ya valve) imakhala ndi mlingo winawake wa elasticity, ndipo pali chilolezo chochepa pakati pa bwana ndi mphete zotanuka mu mphete zotanuka kuti apange. mphete zotanuka pang'ono anasamuka;valavu ikatsekedwa, imakhudzidwa ndi Chifukwa cha mphamvu yotseka, mphete yosindikizira ya elastomer imatha kusunthira kumalo kumene mphamvu imakhala yofanana kwambiri;kuphatikizidwa ndi kapindika kakang'ono ka mphete zotanuka, mphete yosindikizira pampando wa valve imatsindikiridwa mofanana kuti ikwaniritse bwino kusindikiza.
2. Kusintha kwa magwiridwe antchito a mavavu agulugufe okhala ndi mawonekedwe osiyanasiyana:
Pamene chiwerengero cha eccentricity ya mbale valavu ukuwonjezeka, ndipo makulidwe a mbale valavu amakhalanso wandiweyani, kukana kwa madzimadzi akuyenda kudutsa katatu eccentric gulugufe valavu kumawonjezeka;monga kuchuluka kwa eccentricity ya valavu ya butterfly ikuwonjezeka, ntchito ya valve imasinthanso kwambiri.Kuchokera kufananiza ma valve anayi agulugufe osiyanasiyana, zitha kuwoneka kuti valavu yagulugufe yamitundu itatu imatha kutulutsa kutsika kwakukulu ndipo ingagwiritsidwe ntchito ngati valavu yowongolera;kuthamanga kutsika pamene madzi akuyenda kudzera mu valve amawonjezeka ndi kuwonjezeka kwa chiwerengero cha eccentrics;koma poyerekeza ndi mavavu ena omwe si agulugufe, kutsika kwa ma valve agulugufe kudakali kochepa.Pamene chiwerengero cha eccentricity ya valavu ya butterfly ikusintha, ntchito yosindikizira ya mpando wa valve imasinthanso.Valavu yagulugufe wamtundu wamtundu wa katatu ili ndi ntchito yabwino yosindikizira mipando.Pamene chiwerengero cha eccentricities chikuwonjezeka, torque yofunikira pakutsegula ndi kutseka kwa valve imachepa.Choncho, torque yofunika kutsegula ndi kutseka katatu eccentric gulugufe valavu ndi yaying'ono kwambiri kuposa mitundu ina ya mavavu agulugufe.Ndi kusintha kwa chiwerengero cha eccentricity, kutentha ndi kuthamanga kwa kalasi ndi kutentha komwe kumagwiritsidwa ntchito pa valve ya butterfly kudzakhalanso ndi kusintha kwakukulu.Kutentha koyenera komanso kuthamanga kwa ma valve agulugufe katatu sikufanana ndi mitundu ina ya mavavu agulugufe.
3. Ubwino wa triple eccentric butterfly valve:
Kudula bwino Vavu yagulugufe yotsekera patatu imagwiritsa ntchito torque kuti idulire valavu, ndiye kuti pampando wa vavu pamakhala kusindikiza kwabwino kwambiri, motero imatchedwa valavu ya zero.Tinthu tating'onoting'ono kapena dothi m'kati mwake mulibe chikoka chodziwikiratu pa kutsekedwa kwa valve ya butterfly eccentric metal eccentric metal seal, chifukwa pamene valve yatsala pang'ono kutseka, kuthamanga kwa sing'anga kumakhala kwakukulu kwambiri, kotero kuti dothi liri pafupi kutseka. sangathe kudziunjikira pampando valavu.

Nortech ndi m'modzi mwa otsogola opanga ma valve ku China omwe ali ndi chiphaso cha ISO9001.
