Chidule

Valavu ya gulugufe ya NSEN Triple offset Bi-directional imagwiritsa ntchito kapangidwe kotseka ka "Chitsulo chosapanga dzimbiri ndi graphite laminated". Izi zimatsimikizira kuti kutseka kodalirika komanso kukhala ndi moyo wautali pakagwiritsidwa ntchito nthawi zambiri.

• Kutseka kwa zigawo zambiri

• Mphamvu yochepa yotsegulira

• Kutaya madzi konse kwa njira zonse ziwiri

• Palibe kukangana pakati pa mpando ndi kutseka

• Kapangidwe ka chitetezo cha moto kogwirizana ndi API607

• Mpando ndi Chitseko cha Disc Chosinthika

Kapangidwe

Valavu ya gulugufe yopangidwa ndi katatu imawonjezera chozungulira chachitatu chozungulira kutengera kapangidwe kake kawiri. Chozungulira chachitatu chimakhala ndi ngodya inayake.

Pakati pa mzere wapakati wa thupi la valavu ndi nkhope yotsekera mpando yozungulira, zimaonetsetsa kuti mphete yotsekera ya diski ikhoza kulekanitsidwa kapena kukhudzidwa ndi mpando mwachangu kuti kukangana ndi kukanikizana pakati pa mpando ndi mphete yotsekera kuchotsedwe.

Kapangidwe kosindikiza kolunjika mbali ziwiri

Mndandanda uwu ukhoza kufika pamlingo wofanana wa Zero-leakage, kaya mayeso a hydraulic kapena mayeso a mpweya. Kuthamanga kwakukulu komwe kungafike ndi 600LB.

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.

Mphete yosindikizira yosinthika      

Mphete zotsekera za disc ndi mpando zonse ndi zosiyana za NSEN series butterfly valve, ndipo zitha kusinthidwa ngati pakufunika kutero. Mphete yokhala pa disc kapena mpando ikhoza kusinthidwa payekhapayekha ikasweka zomwe sizimangochepetsa ndalama zokonzera komanso zimapangitsa kukonza kukhala kosavuta.

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.

Mphamvu ya Chigawo:Siteshoni yamagetsi yotenthetsera, siteshoni yosinthira kutentha, fakitale ya boiler yachigawo, kuzungulira kwa madzi otentha, makina a mapaipi oyambira

Malo oyeretsera zinthu:Madzi amchere, Mpweya wa carbon dioxide, chomera cha propylene, dongosolo la nthunzi, mpweya wa propylene, chomera cha ethylene, chipangizo chodulira cha ethylene, chomera chophikiraMalo opangira magetsi a nyukiliya:kudzipatula kwa zosungira, njira yochotsera mchere m'madzi a m'nyanja, njira yamadzi amchere, njira yopopera pakati, kudzipatula kwa pampu

Kupanga mphamvu ya kutentha: kuziziritsa kwa condenser, kusungunula kwa pampu ndi nthunzi, chosinthira kutentha, kusungunula kwa condenser, kusungunula kwa pampu

Kutentha kochepa:mpweya wamadzimadzi, makina a gasi wachilengedwe wosungunuka, makina obwezeretsa mafuta m'munda, malo opangira gasi ndi zida zosungira, makina oyendera gasi wachilengedwe wosungunuka

Kuyeretsa mafuta:Kupatula mafuta, valavu yoperekera mpweya, makina ochotsera sulfurization ndi purosesa ya gasi wotayira, mpweya woyaka, kupatula gasi wa asidi, FCCU

Gasi wachilengedwe

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.
