China U Mtundu Gulugufe Valve fakitale ndi opanga

Vavu ya Gulugufe wa U Mtundu

Valavu ya Gulugufe wa Mtundu wa U Chithunzi Chodziwika

Kufotokozera Kwachidule:

Thevalavu ya gulugufe ya U-mtundu wawiriIli ndi kapangidwe kofanana ndi ka wafer, koma ili ndi ma flange ogwirizana mbali zonse ziwiri kuti flange ikhale yolondola komanso yosavuta kuyiyika. Mpando wa rabara umayikidwa bwino kwambiri pa thupi, kuonetsetsa kuti chisindikizo cholimba komanso cholimba popanda zigawo zosiyana za mipando. Yopangidwa motsatira API 609 / EN 593, kukula kwake ndi DN350–DN1200 (14″–48″), mavoti a kuthamanga PN10 / PN16 / PN25 ndi ANSI Class 125/150. Nortech ndi kampani yopanga ma valavu a gulugufe otsogola komanso ogulitsa ku China.

Kapangidwe ka flange kogwirizana kamachotsa kufunikira kwa ma adapter a flange, kuchepetsa nthawi yoyika ndi chiopsezo cha kusakhazikika bwino - kofunikira kwambiri pamapaipi akuluakulu m'mafakitale amadzi, kuthirira, ndi machitidwe opangira mafakitale. Thupi ndi ma disc amapezeka mu ductile iron, carbon steel, chitsulo chosapanga dzimbiri, ndi alu-bronze kuti zigwirizane ndi zinthu zowononga kapena zovuta. Zipangizo za mipando zimaphatikizapo EPDM, NBR, FKM, ndi silicone, zomwe zimaphimba kutentha kosiyanasiyana ndi mitundu yamadzimadzi. ISO 5211 top flange imatsimikizira kuti ikugwirizana mwachindunji ndi ma actuator amanja, amagetsi, ndi pneumatic. Ma valve onse amayesedwa ndikuyang'aniridwa motsatira API 598 / EN 12266.

Valavu ya Gulugufe Yokhala ndi U-Type Yawiri — Chiwonetsero Choyambirira

Kodi valavu ya gulugufe ya U-Type yokhala ndi Flanges ziwiri ndi chiyani?

Thevalavu ya gulugufe ya U-mtundu wawirindi valavu ya gulugufe yokhazikika — yomwe imatchedwanso valavu ya gulugufe ya "concentric", "yokhala ndi rabara", kapena "yokhala ndi rabara". Ili ndi mpando wa rabara wokhazikika womwe umayikidwa mwachindunji pa thupi, pakati pa mainchesi akunja a diski ndi khoma lamkati la valavu, kuonetsetsa kuti kutseka kolimba ngati thovu kumatsimikizika pamitundu yosiyanasiyana.

Valavu yozungulira kotala yomwe imazungulira 90° kuti itsegule kapena kutseka madzi oyenda bwino. Disiki yozungulira — yoyikidwa pakati pa thupi la valavu — imagwira ntchito ngati njira yayikulu yotsekera, yolumikizidwa ku actuator kapena chogwirira kudzera mu shaft yapakati. Disiki ikamaliza kuzungulira kwathunthu kwa madigiri 90, valavu imagwira ntchito ngativalavu yodzipatulaIkatsegulidwa pang'ono, imagwira ntchito ngativalavu yowongolera kuyenda, zomwe zimathandiza kuti munthu azitha kulamulira bwino mbali zosiyanasiyana zotsegulira.

Ponena za njira yokhazikitsira, mtundu wa U umagawidwa ngativalavu yamtundu wa waferNgakhale kuti ili ndi ma flange awiri ophatikizika omwe amaponyedwa pa thupi, miyeso yake yoyang'anizana ndi nkhope ndi yofanana ndi ya mtundu wamba wa wafer - kapangidwe kakang'ono, kogwirizana pakati pa ma flange awiri a mapaipi okhala ndi ma stud omwe amadutsa kuchokera mbali imodzi kupita ku ina. Valavu imagwiridwa pamalo ake ndikutsekedwa ndi ma gasket pansi pa mphamvu ya stud. Ma flange ophatikizika amapangidwa makamaka kuti athandize kulumikizana ndi kuyika, zomwe zimapangitsa kuti kasinthidwe kameneka kakhale chisankho chabwino kwambiri cha ma payipi akuluakulu.

Ku Nortech, ma valve a gulugufe okhazikika okhala ndi mtundu wa wafer ndi lug amaphimba DN32–DN600. Pa mainchesi akuluakulu, valavu ya gulugufe yozungulira ya U imagwiritsidwa ntchito — yomwe imapereka kapangidwe kofanana ndi ka DN350–DN1200 (14″–48″).

Tchati cha CV/KV cha valavu ya gulugufe yokhazikika yokhala ndi U-mtundu chikupezeka ngati mungafune.

Mtundu wa U poyerekeza ndi Wafer poyerekeza ndi Waflangeti iwiri— mitundu itatu yokhazikitsa imakhala ndi kapangidwe kofanana kolimba koma imasiyana momwe imalumikizirana ndi payipi. Kuyerekeza komwe kuli pansipa kukuwonetsa kusiyana kwakukulu pakulumikiza kumapeto ndi njira yokhazikitsa.

DN350–DN1200 PN10 / PN16 / PN25 Kalasi ya ANSI 125/150 Mpando wa rabara wopangidwa ndi vulcanized Kugwirizana kwa flange yophatikizana Yopepuka komanso yopanda kukonza

Kuyerekeza kwa kukhazikitsa kwa valavu ya gulugufe wokhala ndi mpando wolimba — mtundu wa wafer, mtundu wa U, mtundu wopindika kawiri

Kuyerekeza kwa kukhazikitsa: mtundu wa wafer / Mtundu wa U / mtundu wopindika kawiri

Valavu ya Gulugufe ya U-Type — Chiwonetsero Cha Zinthu Zazikulu

Zinthu zazikulu za valavu ya gulugufe yokhazikika yokhala ndi U

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

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

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

Kusankha kwa torque yotsika - kotsika mtengo

Maberiya okhala ndi PTFE — opanda kukonza, palibe mafuta ofunikira

Chovala choyikidwa — chosavuta kusintha, sichiwononga thupi, choyenera kugwiritsidwa ntchito kumapeto kwa mzere

Ma flange ophatikizana — amathandiza kuyika bwino ma valve akuluakulu

Mawonekedwe a chinthu cha mtundu wa U-mtundu wa gulugufe wokhala ndi mpando wolimba
