Flange vavu: mitundu ndi makhalidwe

Flanged vavu anaika pa payipi kuti athe kudya slab madzimadzi otaya ndi kuyanika wotsatira wa chilengedwe. Kuwonjezera chitetezo, zinthu izi zili m'madera onse a maukonde.

mafotokozedwe

Flange bawuti amachita ngati kuli nthambi ndipo ali ndi dongosolo losavuta, ngakhale kukongola mkulu. Imagwera mu gulu la banja mavavu shutoff ndipo ali wapadera lanu chidutswa pakati pa kamangidwe, ntchito umadalira pa mtundu wa vavu yokha. Ambiri ntchito lanu chimbale, flanged mphero ndi mpira chikatikati anthu.

Vavu flange nalo dzina lake chifukwa mphete wapadera flange, yomwe ili pa konsekonse. Iwo ntchito imapatsa mwamsanga dongosolo ndi kuthekera kuchotsa chipangizo kwa m'malo kapena kukonza. Dziwani kuti kukula kwa zimene membala flange ayenera kutsatira ndi mbale yaikulu. Apo ayi, kugwirizana sadzakhala ndi khalidwe moyenera kapena kukhala zosatheka.

Ubwino ndi kuipa

Pakati waukulu lothandiza Dziwani izi:

• kuonetsetsa kukonza mofulumira kapena zotheka kusinthanitsa chipangizo kwa latsopano;
• yosavuta zaphindu Baibulo;
• yaitali moyo utumiki;
• otsika digiri ya kukana hayidiroliki ;
• kudalirika.

The drawback ndicho misa lalikulu. Zimenezi zimabweretsa zinthu kukwera mitengo, makamaka lalikulu, chifukwa kupanga awo amafuna wambirimbiri zakuthupi. Komanso Dziwani ndi avale mofulumira zisindikizo.

mitundu

Latches flange kamapangikira embodiments zosiyanasiyana. Zipangizo anawagawa mitundu ya kanthu lathu - kufanana ndi perpendicular. Njira yamasika n'kupuma ndipo amawachitira mu ubale perpendicular ku mtsinje waukulu. zipangizo kufanana anaika ndi ngodya ya ziro ndipo si chopinga kwa otaya ndi phunziro kupeza mu mode muyezo.

Palinso kusiyana kwa maonekedwe kapangidwe - filimu chipata, mpira ndi zinthu mphero. Yotsirizira ndi anatseka wolemera valavu wa mtundu muyezo. Iwo imathandiza, ndi perpendicular kwa mtundu Letsani, koma amasiyana kulemera kwambiri.

Mpira kapangidwe ali kufanana ndi zinthu lanu la mtundu womwewo wa banja. Ambiri anagula ulamuliro chipangizo 50 chifukwa cha mtengo wotsika. Latch flange 100 ali wapadera ulamuliro litayamba membala kuti overlaps ndi mphamvu mzere wa masika. Nthawi zambiri waikidwa pa mapaipi mafuta ndi kulumikiza mpweya.

Gulu la njira kasamalidwe:

• Dzanja ankaweruza zipangizo. mtundu wa kulamulira anachita ndi pamanja kuyatsa chogwirira kapena vavu wapadera. Ngakhale kufunika ntchito noticeable kugwira ntchito, iwo alibe amafuna yokonza ndi n'zokayikitsa.
• Ainjini mavavu. Iwo ali anamanga-mu galimoto kulamulira. Letsani dongosolo wapangidwa paokha, pambuyo kukanikiza batani.

kantchito

Flanged vavu ukugwira ntchito ranges osiyana a kuthamanga, mlingo pazipita akhoza kufika mazana a mayunitsi. Opaleshoni kutentha ndi mu osiyanasiyana kuchokera madigiri -50 kuti +200. mbali kuponyedwa akusiyana kumatheka katundu, makamaka ntchito ndi zinthu gaseous angayambe pa madigiri 400, ndi madzimadzi natengedwa akhale ndi kutentha 270 madigiri Celsius.

Amaika mumsewu vavu flange amapangidwa makamaka zipangizo monga chitsulo ndi zitsulo. chizindikiro ichi mukusungira chipangizo ankachita. china chilichonse chimene okonzeka ndi flanges ayenera kuwasankha kukula, omwe malamulo ndi zikalata wapadera. Makamaka ankaona diametrical kukula kwa orifice. Ngati pali umboni uliwonse kwa muyezo ichi, kugwirizana kumakhala kovuta. Ngati flange ntchito ogwiritsa zitsulo mankhwala ndi kukula DN 80 kapena DN 50 flange anakafika kumalo omenyera pafupi, ayenera magawo chomwecho. Pamene vavu flange, yomwe ikuchitika mandrel rotational-translational zoyenda pamene adatsegula, kuti angathe kupanga zamitundu yosiyanasiyana. Kukula pazipita kungakhale kwa 1500 mm, zolimba za kukula zing'onozing'ono ali ndi awiri a 25 mm.

Mbali

zinthu Control 80 ndi 50 mphamvu za Ambiri anagula mu mapaipi yachiwiri ndi nthambi mbali kachitidwe. Komanso, ntchito kachitidwe lalikulu ntchito zapakhomo, n'kudzandigunda ndi boilers. Valavu flange 100 losiyana miyeso wokulirapo ndipo anaika waukulu Kutentha ndi madzi okwanira mipope. Zamgululi DN 200 akugwiritsidwa kokha chilengedwe mafakitale vuto la injini zazikulu, zazikulu zomangira wapadera ntchito ogwiritsa. Mtengo wa zolimba zimadalira kukula ndi zinthu kapangidwe. Komanso ali mtengo wapatali ntchito popanga zakuthupi.

unsembe

Assembly of mankhwala opangidwa ndi ndondomeko muyezo. Pa nthawi yomweyo akugwira ntchitoyi wosalira ndi kuwotcherera wa flanges kuti mipope kapena zingwe. Apo ayi, ntchito idzakhala zofunika paokha kulumikiza vavu ndi mbali zina ndi kuwotcherera zinthu payekha chitoliro. Zimenezi kumafuna ndalama ndi nthawi, ndipo amakhala ndi mavuto ena, kulephera zomwe zingathe kubweretsa mavuto pa ntchito. Izi ndi zofunika kwambiri mu gawo mafakitale.

Kudzera mphira kusindikiza mphete membala ndi kuchuluka zikayamba. Iwo waikidwa mu njira, limene lili pa mbale flange. Pa mbali yakutsogolo kwa mbale ayenera kukhala wopanda zoti kuwononga wina aliyense, mwinamwake pali kuthekera kwa depressurization ndi dongosolo BREAKOUT. Zoperekedwa ndi kumaliseche paipi ndi zinadzala ndi mavuto aakulu.
