I-Triple Offset Butterfly Valve DN150–DN500 Lug PN25/PN40 — Ukulethwa Okuqinisekisiwe kwe-CE-PED kanye ne-ATEX eMakethe yaseYurophu

Ukubuka Konke Komkhiqizo

I-Nortech Engineering Corporation isiqede ukulethwa kwenqwaba yamayunithi e-valve e-butterfly aphindwe kathathu ahlanganisa osayizi be-DN150, DN250, DN400, kanye ne-DN500, ezigabeni zokucindezela i-PN25 kanye ne-PN40, konke kusesimisweni sokuxhumeka kohlobo lwe-lug. Umklamo ufinyelela ukuqina okungu-100% okuqondiswa kabili ngaphandle kokuvuza ngaphansi kwezimo ezijwayelekile zokuhlala kanye nokukhululeka kwengcindezi - indinganiso yokusebenza efunwa yizincazelo zesitshalo senqubo yaseYurophu. Iphrofayili yomzimba we-lug ivumela ukufakwa kwensizakalo engapheli ngaphandle kwe-flange engezansi, enikeza ukucushwa kwamapayipi okuguquguqukayo konjiniyela bezitshalo.

Lokhu kuthunyelwa kwakhelwe imakethe yaseYurophu ngenhloso futhi kuhambisana ngokugcwele nezidingo ze-CE-PED (Pressure Equipment Directive) kanye ne-ATEX zokusetshenziswa ezindaweni ezingase ziqhume.

Imininingwane Yobuchwepheshe

Umzimba kanye nebhonethi kukhiqizwa ngensimbi yekhabhoni engu-1.0619+N, ehlanganiswe ngomshini ukuze kuqinisekiswe ukuthi i-triple-offset geometry inembile kanye nokuxhumana kwesihlalo okuhambisanayo. Idiski iphonswa ngensimbi engagqwali engu-1.4408 austenitic (elingana ne-CF8M), enikeza ukumelana nokugqwala kuzo zonke izinhlobo zemidiya yenqubo. Isiqu sakhiwe ngensimbi engagqwali eqina imvula engu-17-4PH, ekhethwe ngenxa yamandla ayo aphezulu okukhiqiza kanye nokumelana nokukhathala ngaphansi kwemithwalo ye-torque ejikelezayo.

Uhlelo lwesihlalo sensimbi luqinile eStellite phezu kwezihlalo ukuze lungagugi, luqhekeke, futhi lungalimali ngokushisa emazingeni okushisa aphezulu. Indandatho yokuvala ihlanganisa insimbi engagqwali ye-S32750 super duplex nesendlalelo se-graphite laminate, ihlinzeka ngokusebenza kokuvala okuvikela umlilo kanye nobuqotho obuqhubekayo ekusebenzeni komjikelezo ophezulu. Ukuxhumeka kokugcina kuhlobo lwe-lug kuya ku-EN 1092-1 ubukhulu bokugoba; umklamo ojwayelekile we-EN 593.

Isicelo Nokulethwa

Leli qoqo lanikezwa umsabalalisi waseYurophu okhonza imikhakha yokucwenga, i-petrochemical, kanye nokukhiqizwa kwamandla. Isitifiketi se-ATEX butterfly valve sifanela lawa mayunithi ukufakwa kwezindawo eziyingozi ze-Zone 1 kanye ne-Zone 2 lapho ukulawulwa kwengozi yokusha kuyimpoqo. Ukulungiswa okuningi kwabasebenzi kufakiwe ekulethweni - izinhlangano zamagiya esandla zosayizi abakhulu be-DN400 kanye ne-DN500, kanye namaphakheji e-pneumatic actuator amayunithi e-DN150 kanye ne-DN250 - ahlanganisa uhla oluphelele lwezidingo zokuzenzakalela kwesayithi.

Njengomhlinzeki okhethekile wamavalvu e-butterfly asezingeni eli-3, i-Nortech inikeza amaphakheji evalvu ahambisana ne-CE-PED kuma-oda esitoko namaphrojekthi aseYurophu, kanye nokulandeleka okugcwele kwezinto kanye nokuhlolwa komuntu wesithathu okutholakala uma kuceliwe.
