Valavu ya Gulugufe Yopatukana Katatu DN150–DN500 Lug PN25/PN40 — Kutumiza Kotsimikizika kwa CE-PED ndi ATEX ku Msika waku Europe

Chidule cha Zamalonda

Nortech Engineering Corporation yamaliza kutumiza ma valve atatu a butterfly omwe ali ndi kukula kwa DN150, DN250, DN400, ndi DN500, m'magulu opanikizika a PN25 ndi PN40, onse ali mu mawonekedwe a kulumikizana kwa mtundu wa lug. Kapangidwe kake kamakwaniritsa kulimba kwa 100% mbali zonse ziwiri popanda kutayikira pansi pa mikhalidwe yabwinobwino yokhala pansi komanso yochepetsera kupsinjika - muyezo wogwirira ntchito womwe umafunika ndi zomwe zimapangidwa ndi mafakitale aku Europe. Mbiri ya thupi la lug imalola kuyika ntchito yopanda flange yotsika, kupereka mawonekedwe osinthika a mapaipi kwa mainjiniya a mafakitale.

Kutumiza kumeneku kunapangidwira msika waku Europe ndipo kukutsatira kwathunthu malamulo a CE-PED (Pressure Equipment Directive) ndi zofunikira pagulu la ATEX kuti zigwiritsidwe ntchito m'mlengalenga womwe ungaphulike.

Mafotokozedwe Aukadaulo

Thupi ndi bonnet zimapangidwa mu chitsulo cha kaboni cha 1.0619+N, chopangidwa ndi makina kuti chikhale ndi miyeso yolimba kuti zitsimikizire kuti mawonekedwe ake ndi atatu komanso kuti mpando wake ugwirizane bwino. Disikiyi imapangidwa mu chitsulo chosapanga dzimbiri cha austenitic cha 1.4408 (chofanana ndi CF8M), chomwe chimapereka kukana dzimbiri pamitundu yosiyanasiyana ya zinthu. Tsinde lake limapangidwa kuchokera ku chitsulo chosapanga dzimbiri cha 17-4PH, chomwe chimasankhidwa chifukwa cha mphamvu zake zambiri komanso kukana kutopa pansi pa mphamvu ya torque.

Dongosolo la mipando yachitsulo ndi lolimba la Stellite pamwamba pa mipando kuti lisagwedezeke, lisungunuke, komanso liwonongeke ndi kutentha kwambiri kutentha kwambiri. Mphete yosindikizira imaphatikiza chitsulo chosapanga dzimbiri cha S32750 super duplex ndi graphite laminate layer, zomwe zimapangitsa kuti chisindikizo chizigwira ntchito bwino komanso kuti chikhale cholimba nthawi zonse. Kulumikiza kumapeto kuli ndi mtundu wa lug to EN 1092-1 flanging dimensions; kapangidwe kake ndi muyezo wa EN 593.

Kugwiritsa Ntchito & Kutumiza

Gulu ili linaperekedwa kwa wogulitsa wa ku Europe amene amatumikira magawo oyeretsera, mafuta, ndi kupanga mphamvu. Chitsimikizo cha valavu ya butterfly ya ATEX chimayeneretsa mayunitsi awa kuti akhazikitsidwe m'malo oopsa a Zone 1 ndi Zone 2 komwe kuwongolera zoopsa ndikofunikira. Makonzedwe angapo a opareshoni adaphatikizidwa mu kutumiza - ma gearbox assemblies amanja a kukula kwakukulu kwa DN400 ndi DN500, ndi ma phukusi a pneumatic actuator a mayunitsi a DN150 ndi DN250 - omwe amaphimba zofunikira zonse zodziyimira pawokha pamalopo.

Monga kampani yopereka ma valvu a gulugufe atatu, Nortech imapereka ma valvu ogwirizana ndi CE-PED a maoda a katundu ndi mapulojekiti aku Europe, ndi kutsata kwathunthu kwa zinthu ndi kuwunika kwa chipani chachitatu komwe kungapezeke ngati kupemphedwa.
