Chidule

Valavu ya gulugufe ya NSEN Triple offset uni-directional imagwiritsa ntchito kapangidwe kotseka ka "Chitsulo chosapanga dzimbiri ndi graphite laminated". Mndandanda uwu ukhoza kufikira kufunikira kwa uni-directional Zero-leakage mu muyezo wofanana. Zipangizo zodulira zimapangidwa ndi chitsulo chosapanga dzimbiri chapamwamba, chomwe chingapewe vuto la dzimbiri mutagwiritsa ntchito kwa nthawi yayitali.

• Kutseka kwa zigawo zambiri ndi kutseka kwachitsulo cholimba

• Mphamvu yochepa yotsegulira

• Palibe kukangana pakati pa mpando ndi kutseka

• Kapangidwe ka chitetezo cha moto kogwirizana ndi API607

• Kutseka Ma Disc Komwe Kungasinthidwe

Kulemba kwa Valavu:MSS-SP-25
Kapangidwe ndi Kupanga:API 609, EN 593
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

Valavu ya gulugufe yopangidwa ndi katatu imawonjezera mawonekedwe achitatu a eccentric kutengera kapangidwe kake kawiri. Choyimitsa chachitatu chimakhala ndi ngodya inayake pakati pa mzere wapakati wa thupi la valavu ndi nkhope yotsekera mpando yozungulira, zomwe zimapangitsa kuti mphete yotsekera ya diski ikulekanitsidwa kapena kukhudzidwa ndi mpando mwachangu kuti kukangana ndi kukanikizana pakati pa mpando ndi mphete yotsekera kuchotsedwe.

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.

Nyanjalmphete        
Mphete yotsekera ya seriyi imapangidwa ndi mbale yachitsulo chosapanga dzimbiri yokhala ndi graphite/carbon fiber/PTFE etc. Kutsekera kwakukulu ndi mbale yachitsulo chosapanga dzimbiri, yopanda chitsulo ngati chothandizira. Kapangidwe kameneka kamapangitsa kuti valavu ikhale yotsekedwa bwino ndipo kutuluka kwa kutsekerako kufika pa VI class kupita ku ANSI B16.104 kapena A class kupita ku ISO 5208. Poyerekeza ndi mbale ya asbestos ya rabara, zipangizo zathu zogwiritsa ntchito ndizosavuta kuvala, zoletsa kusamba, zodalirika komanso zabwino kwa chilengedwe.

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.

Kapangidwe ndi kapangidwe kake koteteza moto      

Kapangidwe ka chitsulo kamapangitsa kuti mavavu azitetezedwa ku moto ndipo amakwaniritsa zofunikira mu API 607.

Bokosi la zida

Bokosi la giya lamanja loperekedwa mwapamwamba komanso mwachitetezo, lomwe laphatikizidwa ndi zida zodziwika bwino za giya la mtundu wamakono komanso mulingo woteteza umafika pa IP 67.

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.
