Ivalvu yeButterfly ye-Offset kathathu i-DN150–DN500 Lug PN25/PN40 — Ukuhanjiswa okuqinisekisiweyo kwe-CE-PED kunye ne-ATEX kwiMarike yaseYurophu

Isishwankathelo seMveliso

I-Nortech Engineering Corporation igqibe ukuhanjiswa kweeyunithi zevalvu ze-butterfly ezi-triple offset ezigubungela ubungakanani be-DN150, DN250, DN400, kunye ne-DN500, kwiiklasi zoxinzelelo lwe-PN25 kunye ne-PN40, zonke zikwisimo soqhagamshelo lohlobo lwe-lug. Uyilo lufikelela kwi-100% yokuqina kwecala eli-bi-directional ngaphandle kokuvuza phantsi kweemeko eziqhelekileyo zokuhlala kunye nokunciphisa uxinzelelo - umgangatho wokusebenza ofunwa ziinkcazo zezityalo zenkqubo zaseYurophu. Iprofayili yomzimba we-lug ivumela ukufakwa kwenkonzo engapheliyo ngaphandle kwe-flange esezantsi, inikezela ngoqwalaselo oluguquguqukayo lwemibhobho kwiinjineli zezityalo.

Olu thutho lwakhiwe ngenjongo yemarike yaseYurophu kwaye luhambelana ngokupheleleyo ne-CE-PED (Pressure Equipment Directive) kunye neemfuno zokuhlelwa kwe-ATEX ukuze zisetyenziswe kwiindawo ezinokuqhuma.

Iinkcukacha zobugcisa

Umzimba kunye nebhonethi ziveliswa ngentsimbi yekhabhoni eyi-1.0619+N, zenziwe ngomatshini ukuze zilingane kakuhle ukuqinisekisa ukuba i-triple-offset geometry ilungile kwaye ihambelana nesihlalo rhoqo. Idiski iphoswe kwintsimbi engagqwaliyo eyi-1.4408 austenitic (equivalent CF8M), inika ukumelana nokugqwala kwiindidi ezahlukeneyo zeenkqubo. Isiqu senziwe ngentsimbi engagqwaliyo ye-17-4PH precipitation-hardening, ekhethwe ngenxa yamandla ayo aphezulu kunye nokumelana nokudinwa phantsi kwemithwalo ye-torque ejikelezayo.

Inkqubo yesihlalo sesinyithi iqinile kwiStellite kumphezulu wezihlalo ukuze imelane nokukrala, ukurhawuzelelwa, kunye nomonakalo wokujikeleza kobushushu kumaqondo obushushu aphezulu. Indandatho yesitywina idibanisa intsimbi engagqwaliyo ye-S32750 super duplex kunye nomaleko we-graphite laminate, inika ukusebenza kokutywina okukhuselekileyo emlilweni kunye nokuthembeka okuqhubekayo kuyo yonke imisebenzi yomjikelo ophezulu. Uqhagamshelo lokugqibela luhlobo lwe-lug kwi-EN 1092-1 ubukhulu be-flanging; uyilo oluqhelekileyo lwe-EN 593.

Isicelo kunye nokuHanjiswa

Le bhetshi inikwe umsasazi waseYurophu okhonza amacandelo okucoca, i-petrochemical, kunye nokuvelisa amandla. Isatifikethi se-ATEX butterfly valve sivumela ezi yunithi ukuba zifakelwe indawo enobungozi yeZone 1 kunye neZone 2 apho ulawulo lomngcipheko wokutsha luyimfuneko. Uqwalaselo oluninzi lwabaqhubi lubandakanyiwe kwi-delivery — ii-manual gearbox assemblies ze-DN400 kunye ne-DN500 ezinkulu, kunye neepakethe ze-pneumatic actuator zeeyunithi ze-DN150 kunye ne-DN250 — ezigubungela uluhlu olupheleleyo lweemfuno ze-automation yesiza.

Njengomthengisi weevalvu zeebhabhathane eziziingcali ze-triple offset, iNortech ibonelela ngeepakethe zeevalvu ezihambelana ne-CE-PED zee-odolo zesitokhwe kunye neeprojekthi zaseYurophu, kunye nokulandeleka okugcweleyo kwezinto kunye nokuhlolwa komntu wesithathu okufumaneka xa kuceliwe.
