ʻO ka Triple Offset Butterfly Valve DN150–DN500 Lug PN25/PN40 — CE-PED a me ATEX Certified Delivery no ka Mākeke ʻEulopa

ʻIke Huahana

Ua hoʻopau ʻo Nortech Engineering Corporation i kahi hāʻawi pūʻulu o nā ʻāpana valve butterfly offset triple e uhi ana i nā nui DN150, DN250, DN400, a me DN500, ma nā papa kaomi PN25 a me PN40, a pau i loko o ka hoʻonohonoho pili hopena ʻano lug. Hoʻokō ka hoʻolālā i ka 100% bi-directional tightness me ka ʻole o ka leakage ma lalo o nā kūlana noho maʻamau a me nā kūlana hoʻomaha kaomi - kahi kūlana hana i koi ʻia e nā kikoʻī o ka hale hana hana ʻEulopa. ʻAe ka ʻaoʻao kino lug i ka hoʻokomo ʻana i ka lawelawe dead-end me ka ʻole o kahi flange downstream, e hāʻawi ana i ka hoʻonohonoho paipu maʻalahi no nā ʻenekinia hale hana.

Ua kūkulu ʻia kēia ukana no ka mākeke ʻEulopa a ua kūlike piha me nā koi hoʻokaʻawale CE-PED (Pressure Equipment Directive) a me ATEX no ka hoʻohana ʻana i nā lewa pahū.

Nā Kikoʻī ʻenehana

Hana ʻia ke kino a me ka pāpale i ke kila kalapona 1.0619+N, i mīkini ʻia i nā ʻae ʻana o ka dimensional paʻa e hōʻoia i ka geometry triple-offset pololei a me ka pili like ʻana o ka noho. Hoʻoheheʻe ʻia ka disc i loko o ke kila kila austenitic 1.4408 (CF8M like), e hāʻawi ana i ke kūpaʻa i ka pala ma nā ʻano hana like ʻole. Hana ʻia ke kumu mai ke kila kila paʻakikī-wai 17-4PH, i koho ʻia no kona ikaika hua kiʻekiʻe a me ke kūpaʻa luhi ma lalo o nā ukana torque cyclic.

Ua uhi ʻia ka ʻōnaehana noho metala me ka Stellite paʻa ma luna o ka ʻili noho e pale aku i ka ʻānai ʻana, ka huhū, a me ka pōʻino o ke kaʻapuni wela i nā mahana kiʻekiʻe. Hoʻohui ke apo sila i ke kila kila S32750 super duplex me kahi papa laminate graphite, e hāʻawi ana i ka hana sila palekana ahi a me ka kūpaʻa mau ma waena o ka hana kaʻapuni kiʻekiʻe. ʻO ka pilina hopena he ʻano lug i nā ana flanging EN 1092-1; kūlana hoʻolālā EN 593.

Noi a me ka Hoʻouna ʻana

Ua hoʻolako ʻia kēia pūʻulu i kahi mea hoʻolaha ʻEulopa e lawelawe ana i nā ʻāpana hoʻomaʻemaʻe, petrochemical, a me ka hana ikehu. ʻO ka palapala hōʻoia valve butterfly ATEX e hōʻoia i kēia mau ʻāpana no nā hoʻonohonoho wahi weliweli ʻo Zone 1 a me Zone 2 kahi e koi ʻia ai ka kaohi ʻana i ka pilikia hoʻā. Ua hoʻokomo ʻia nā hoʻonohonoho mea hoʻohana he nui i ka lawe ʻana - nā ʻākoakoa pahu pahu lima no nā nui DN400 a me DN500 nui aʻe, a me nā pūʻolo actuator pneumatic no nā ʻāpana DN150 a me DN250 - e uhi ana i nā koi piha o ka automation kahua.

Ma ke ʻano he mea hoʻolako loea i ka valve butterfly triple offset, hāʻawi ʻo Nortech i nā pūʻolo valve CE-PED-compliant no nā waihona ʻEulopa a me nā kauoha papahana, me ka hiki ke loaʻa nā mea piha a me ka nānā ʻana mai nā ʻaoʻao ʻekolu ma ke noi.
