Kupititsa patsogolo ndi Kugwiritsa Ntchito kwa Metal Seal Butterfly Valve

Triple-Eccentric-Butterfly-Valve-300x300 Triple-Eccentric-Butterfly-Valve-02-300x300
Kuipa kwa valavu ya gulugufe ya rubber seal ndikuti ikagwiritsidwa ntchito pogwedeza, cavitation idzachitika chifukwa chogwiritsidwa ntchito molakwika, zomwe zimapangitsa kuti mpando wa mphira uwonongeke ndi kuwonongeka.Pachifukwa ichi, ma valve agulugufe osindikizidwa ndi zitsulo apangidwa padziko lonse lapansi, ndipo cavitation zone yachepetsedwa.M'zaka zaposachedwapa, dziko langa lapanganso ma valve agulugufe osindikizidwa ndi zitsulo.Ku Japan, mavavu agulugufe ooneka ngati chisa okhala ndi cavitation resistance, kugwedera kochepa komanso phokoso lochepa apangidwanso zaka zaposachedwa.
Nthawi zambiri, moyo wa mpando wosindikizira wa gulugufe ndi zaka 15-20 mphira ndi zaka 80-90 zachitsulo pansi pazikhalidwe.Komabe, kusankha kolondola kumadalira zofunikira pamikhalidwe yogwirira ntchito.
Mgwirizano wapakati pa digiri yotsegulira ya zitsulo zosindikizira gulugufe valavu ndi kuthamanga kwa kayendedwe kamasintha kwenikweni.Ngati imagwiritsidwa ntchito kuwongolera kuthamanga, mawonekedwe ake oyenda nawonso amagwirizana kwambiri ndi kukana kwa mipope.Mwachitsanzo, mapaipi awiri amaikidwa ndi m'mimba mwake ndi mawonekedwe a valve, koma kutayika kwa payipi kumakhala kosiyana, ndipo kuthamanga kwa valve kudzakhalanso kosiyana kwambiri.Ngati valavu ili m'chigawo chokhala ndi phokoso lalikulu, kumbuyo kwa mbale ya valve kumakhala kosavuta ku cavitation, zomwe zingawononge valavu.Nthawi zambiri, imagwiritsidwa ntchito kunja kwa 15 °.
Pamene kusintha kwa gulugufe wachitsulo chosindikizira kuli pakati pa kutseguka, mawonekedwe otsegula opangidwa ndi thupi la valve ndi kutsogolo kwa gulugufe amayang'ana pazitsulo za valve, ndipo mbali ziwirizo zimapangidwira kuti zikwaniritse mayiko osiyanasiyana.Kutsogolo kwa mbale ya gulugufe kumbali imodzi kumayenda molunjika kumadzi oyenda, ndipo mbali inayo kumapita chammbuyo.Choncho, mbali imodzi ya thupi la valve ndi mbale ya valve imapanga kutsegula ngati nozzle, ndipo mbali inayo ndi yofanana ndi kutsegula kwa throttle.Mbali yamphuno imakhala ndi liwiro lothamanga kwambiri kuposa mbali ya throttle, ndipo valavu ya throttle imatulutsa Kupanikizika, zisindikizo za rabara nthawi zambiri zimagwa.
Ma torque ogwiritsira ntchito agulugufe osindikizira achitsulo amakhala ndi zinthu zosiyanasiyana chifukwa cha kutseguka komanso kutsekera kosiyanasiyana kwa valavu.Valavu yagulugufe yopingasa, makamaka valavu yagulugufe yamtundu waukulu, chifukwa cha kuya kwa madzi, torque yomwe imapangidwa ndi kusiyana pakati pa mitu yamadzi yam'mwamba ndi yapansi ya shaft ya valve singakhoze kunyalanyazidwa.Kuonjezera apo, pamene chigongono chimayikidwa kumbali yolowera ya valve, kutuluka kwa tsankho kumapangidwa ndipo torque idzawonjezeka.Valavu ikakhala pakatikati potsegulira, njira yogwirira ntchito iyenera kudzitsekera yokha chifukwa chakuchita kwa torque yamadzi.

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