Kufotokozera Kwachidule:

Thevavu ya gulugufe ya flange iwiriNdi valavu ya gulugufe yokhazikika yokhala ndi ma flange ophatikizika mbali zonse ziwiri, zomwe zimathandiza kuti pakhale kulumikizana mwachindunji ndi payipi popanda ma adapter ena a flange. Mpando wa rabara umayikidwa bwino pa thupi, kuonetsetsa kuti umakhala wotetezeka kutseka mbali ziwiri. Monga valavu yozungulira kotala, imagwira ntchito ngati valavu yodzipatula komanso valavu yowongolera kuyenda kwa madzi m'makona osiyanasiyana otseguka. Yoyenera ntchito yomaliza. Yopangidwa motsatira API 609 / EN 593, yoyang'anizana ndi maso motsatira ISO 5752 / EN 558-1 Series 13, flange end EN 1092-2 PN10/PN16/PN25 ndi ANSI Class 125/150. Kukula kwake ndi DN50–DN1200. Thupi ndi diski mu ductile iron, carbon steel, stainless steel, kapena alu-bronze. Zipangizo za mipando: EPDM, NBR, FKM, silicone. Nortech ndi wopanga ma valavu a gulugufe ophatikizana awiri komanso ogulitsa ku China.

Valavu ya Gulugufe Wachiwiri wa Flange — Chiwonetsero Choyambirira

Kodi valavu ya gulugufe ya Flange iwiri ndi chiyani?

Thevavu ya gulugufe ya flange iwirindi valavu ya gulugufe yokhazikika yokhala ndi ma flanges ophatikizika mbali zonse ziwiri, zomwe zimathandiza kulumikizana mwachindunji ndi payipi popanda ma adaputala ena. Monga mavalavu onse a gulugufe okhazikika, ndi valavu yozungulira kotala: disc yozungulira yomwe imayikidwa pakati pa thupi imagwira ntchito ngati njira yotsekera, yolumikizidwa ku actuator kapena chogwirira kudzera mu shaft yapakati. Kuzungulira kwathunthu kwa madigiri 90 kumatsegula kapena kutseka valavu yonse yantchito yodzipatula.

Ngati diski siizungulira mpaka kutembenuka konse kwa kotala, valavu imakhala yotseguka pang'ono - zomwe zimathandiza kuti igwire bwino ntchitomalamulo oyendetsera kayendedwe ka madzipa ngodya zosiyanasiyana zotsegulira. Mpando wa rabara umayikidwa bwino kwambiri pa thupi, kuonetsetsa kuti umakhala wotetezeka komanso wotetezeka m'mbali zonse ziwiri, kuphatikizapo wovuta.mikhalidwe yogwirira ntchito ya vacuum.

Ma valve a gulugufe a Nortech okhala ndi flange iwiri amapangidwa ndi mulingo wautali wofanana ndi EN 558-1 Series 13, zomwe zimapangitsa kuti akhale oyenera kugwiritsidwa ntchito m'njira zosiyanasiyana kuphatikizapo maukonde ogawa madzi, malo oyeretsera madzi, madamu, malo opangira magetsi, ndi makina a mapaipi akuluakulu. Valavu iyi ingagwiritsidwe ntchito ngati valavu yodzipatula, pompo yotulutsira madzi kumapeto kwa payipi, kapena chipangizo chowongolera kuyenda kwa madzi. Pa mapaipi akuluakulu, kasinthidwe ka flange kawiri ndiye chisankho chokhazikika.

Tchati cha CV/KV cha vavu ya gulugufe yokhazikika yokhala ndi flange iwiri chikupezeka ngati mungafune.

Kuyang'anana maso ndi maso nthawi yayitali ndi EN 558-1 Series 13— kapangidwe ka double flange kamapereka kulumikizana kolimba, kodzichirikiza komwe kumagwirizana makamaka ndi mapaipi akuluakulu komanso ntchito zamagalimoto ambiri komwe kukhazikika ndi kulumikizana kwa mavavu ndikofunikira.

DN50–DN1200 PN10 / PN16 / PN25 EN 558-1 Mndandanda 13 Mpando wa rabara wopangidwa ndi vulcanized Utumiki womaliza Kudzipatula ndi kuwongolera kayendedwe ka madzi

Valavu ya Gulugufe Wachiwiri wa Flange — Chiwonetsero Cha Zinthu Zazikulu

Mbali zazikulu za valavu ya gulugufe ya flange iwiri

Kapangidwe kakang'ono — kulemera kochepa, malo ochepa osungiramo zinthu ndi malo oyikapo

Shaft yapakati, kutseka kolimba kwa thovu kozungulira mbali zonse ziwiri, njira iliyonse yoyikira

ISO 5211 flange yapamwamba - yosavuta kuyimitsa yokha komanso kukonzanso kwa actuator

Thupi lonse lodzaza ndi chitoliro — kukana kuyenda bwino kwa madzi

Njira yolowera madzi yopanda mabowo — yosavuta kuyeretsa komanso yophera tizilombo toyambitsa matenda, yoyenera madzi akumwa

Thupi lokhala ndi rabara — madzi sagwirana ndi thupi lachitsulo

Kapangidwe ka ma diski opanda pin - kamachotsa njira zotayikira pa diski

Kusankha kwa torque yotsika - kotsika mtengo

Maberiya okhala ndi PTFE — opanda kukonza, palibe mafuta ofunikira

Mpando wa rabara wolumikizidwa ndi chivundikiro cholimba — chotseka chokhazikika, choyenera kugwiritsidwa ntchito pochotsa mpweya m'malo otseguka komanso ntchito yomaliza.
