Valavu ya gulugufe ya NSEN Lug Triple offset imagwiritsidwa ntchito kwambiri m'mafakitale a zamkati ndi mapepala, mankhwala, petrochemical ndi refinering. Valavu ya gulugufe yolimba kwambiri imagwira ntchito zonse ziwiri zowongolera komanso zozimitsa.

• Kutseka kokhala ndi laminated & Kutseka kwachitsulo kuchokera kuchitsulo kupita kuchitsulo

• Yolunjika mbali zonse ziwiri ndi yolunjika mbali imodzi

• Mphamvu yochepa yotsegulira

• Palibe kukangana pakati pa mpando ndi kutseka

• Nkhope yotseka yokhotakhota

• Chotengera chodzola

Kulemba kwa Valavu:MSS-SP-25
Kapangidwe ndi Kupanga:API 60
Kukula kwa Maso ndi Maso:API 609, ISO 5752, EN 558
Kulumikiza Komaliza:ASME B16.5, ASME B16.47, EN 1092, JIS B2220, GOST 12820
Mayeso ndi Kuyang'anira:API 598, EN 12266, ISO 5208, ANSI B16.104

NSEN imapereka mwayi wokonza mpando wokhazikika ndi mpando woyandama womwe ungakonzedwe popanda kuchotsa valavu pamalo pake, izi zitha kufupikitsa nthawi yokonza ndikuwonjezera magwiridwe antchito. Mpando wokhazikika umagwiritsidwa ntchito pa valavu pomwe kuyenda kwapakati kumapita patsogolo, kotero kutseka kolimba kumangoyang'ana mbali imodzi, ndipo kuyenera kulabadira njira yoyendera pamene idayikidwa. Ngakhale mpando uli wokhazikika, koma kutseka kwa disc kumatha kuchotsedwa. Ngati valavu igwira ndi mpando woyandama, mutha kuyiyika mbali iliyonse.

Mphamvu yotsika yotsegulira

Chigawochi chimagwiritsa ntchito Radial Dynamically Balanced Sealing System, pogwiritsa ntchito kapangidwe kabwino kwambiri, mphamvu zomwe zimagwiritsidwa ntchito mbali zonse ziwiri kuti zilowe ndi kutuluka kwa ma disc a gulugufe zimakhala zofanana kuti zichepetse mphamvu yotsegulira ma valve.

Kudzipaka mafutachogwirira

Pofuna kuchepetsa mphamvu yogwirira ntchito komanso kupewa kutsekeka kwa tsinde pamene likutsegulidwa ndi kutsekedwa nthawi zambiri, bushing yodzipangira yokha yagwiritsidwa ntchito.

Nyanjalmphete        
Mphete yotsekera yopangidwa ndi laminated imapangidwa ndi mbale yachitsulo chosapanga dzimbiri yokhala ndi graphite/carbon fiber/PTFE etc. Poyerekeza ndi mbale ya rabara ya asbestos, zinthu zathu zogwiritsa ntchito ndizosavuta kuvala, sizimatsuka, ndizodalirika komanso ndizabwino kwa chilengedwe.

Mphete ya mpando yopangidwa ndi valavu ya gulugufe yotsekedwa ndi chitsulo imapangidwa ndi chitsulo chopangidwa ndi alloy chomwe chili ndi ubwino woletsa kukanda, kukana kutopa, kukana kuthamanga kwambiri ndi kutentha komanso kukhala ndi moyo wautali.

Pkukwiya-kutseka kophatikizanadongosolo
NSEN imagwiritsa ntchito kapangidwe kameneka kuti iwonetsetse kuti kutuluka kwa valavu kumatha kufika pa ≤20ppm pamlingo wapamwamba kwambiri. Kapangidwe kotseka kamphamvu kamapezeka ngati pakufunika, zomwe zimapangitsa kuti kutseka kwa kulongedza kukhale bwino ndikuwonjezera nthawi yokonza yaulere yolongedza.

Kapangidwe Kokhazikika Molingana      

Mphete yotsekera ya valavu ya gulugufe imakhazikika ndi mabolu/mtedza wogawidwa mofanana. Boluti iliyonse imakhala pamalo oyenera ndipo imakhala ndi mphamvu zofanana. Kapangidwe kameneka kamathetsa mavuto a kutayikira kapena kutayikira kwa mphete chifukwa cha mphamvu yosagwirizana ya maboluti ndi mtedza.

NSEN ikutsatira mosamalitsa ntchito zokonza zaulere, kusintha kwaulere ndi kubwezeretsa kwaulere mkati mwa miyezi 18 valavu itatha ntchito zakale kapena miyezi 12 itatha kuyikidwa ndikugwiritsidwa ntchito pa payipi pambuyo pa ntchito zakale (ndipo imayamba poyamba). 

Ngati valavu yalephera chifukwa cha vuto la khalidwe panthawi yogwiritsa ntchito mapaipi mkati mwa nthawi ya chitsimikizo cha khalidwe, NSEN ipereka chitsimikizo cha khalidwe chaulere. Ntchitoyi siidzatha mpaka kulephera kukhazikika ndipo valavuyo ikugwira ntchito bwino komanso kasitomala atasaina kalata yotsimikizira.

Pambuyo pa nthawi yomwe yatchulidwa, NSEN imatsimikizira kuti idzapatsa ogwiritsa ntchito ntchito zaukadaulo zabwino pa nthawi yake nthawi iliyonse yomwe chinthucho chikufunika kukonzedwa ndi kusamalidwa.
