Valavu ya gulugufe ya mtundu wa NSEN Weld Triple offset ingapereke kutseka kwa laminated komanso kutseka kwachitsulo chonse. Thupi lopangidwa liyenera kugwiritsidwa ntchito pa mndandanda uwu, likhoza kupewa kumasuka kwamkati komwe sikungawonekere panthawi yopangira zinthu komanso zolakwika za mphamvu ya thupi ndi mphamvu ya axial pogwiritsa ntchito njira yolumikizira mbale. Kuwunika kwa NDE kudzachitika ngati makasitomala atapempha, titha kupereka chithandizo chokonzekera.

Kapangidwe

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.

Kapangidwe kopanda mikangano

Kugwiritsa ntchito kapangidwe ka eccentric katatu komwe kumachepetsa kukangana pakati pa malo otsekera a diski ndi thupi la valavu, kuti diskiyo ichotse mwachangu mpando wa valavu ikatsegulidwa kapena kutsekedwa ndi valavu ya gulugufe ya eccentric katatu.

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.

Kunyamula mafuta

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

Kapangidwe ka tsinde loletsa kuphulika

Valavu iliyonse imawonjezera kapangidwe koteteza kuphulika pamalo ake a tsinde motsatira API609 yokhazikika.

Mmlengalenga        
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.

Zipangizo zodulira zimapangidwa ndi chitsulo chosapanga dzimbiri chapamwamba kwambiri, zitha kupewa vuto la dzimbiri mutagwiritsa ntchito kwa nthawi yayitali.

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 chophikira

Malo 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

Zamkati ndi pepala:kudzipatula kwa nthunzi, madzi ophikira, laimu ndi matope

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.
