Ma Vavu A M'mbali Okwera Eccentric Half-Ball
Mawonekedwe
▪ Mapangidwe a eccentric amachepetsa kutseguka kwa torque, amachepetsa kukangana kwa malo osindikizira ndikutalikitsa moyo wautumiki.
▪ Kukaniza kwamadzimadzi kumakhala kochepa, ndipo mphamvu yake yotsutsa ndi yofanana ndi gawo la chitoliro ndi kutalika kwake.
▪ Mpando wophimbidwa ndi mphira kapena zitsulo kuti muwonetsetse kuti valavu ingagwiritsidwe ntchito mosiyana.
▪ Ndi kusindikizidwa kolimba ndipo palibe kutayikira kwa mpweya woipa.
▪ Kuthamanga kwa mayeso:
Kupanikizika kwa Shell Test 1.5 x PN
Kuthamanga kwa Chisindikizo 1.1 x PN
▪ Kusankhidwa kwa bimetallic sealing awiriawiri okhala ndi aloyi wosiyanasiyana (kapena mpira wophatikizika) wokwera angagwiritsidwe ntchito pogwira ntchito ndi kukana kuvala, kukana dzimbiri, kukana kutentha kwambiri komanso zofunikira zosindikizira:
1. Valavu yogwiritsidwa ntchito kawirikawiri: Kukula kwa DN40 ~ 1600, koyenera kuyeretsa zimbudzi, zamkati, kutentha kwa mizinda ndi nthawi zina ndi zofunikira zokhwima.
2. Valavu yapadera ya mafakitale a petrochemical: Kukula kwa DN140 ~ 1600. Ndikoyenera kwa mafuta osakanizika, mafuta olemera ndi zinthu zina zamafuta, zowonongeka zofooka ndi magawo awiri osakanikirana osakanikirana m'makampani opanga mankhwala.
3. Valavu yapadera ya gasi: Kukula kwa DN40 ~ 1600, yogwiritsidwa ntchito poyendetsa gasi, gasi wachilengedwe ndi mpweya wamadzimadzi.
4. Valavu yapadera ya slurry: Kukula kwa DN40 ~ 1600, yogwiritsidwa ntchito poyendetsa mapaipi a mafakitale ndi mpweya wa crystallization kapena makulitsidwe mumadzimadzi ndi olimba a magawo awiri osakanikirana othamanga kapena mankhwala mumayendedwe amadzimadzi.
5. Vavu yapadera ya phulusa la malasha: Kukula kwa DN140 ~ 1600. Imagwiritsidwa ntchito poyang'anira magetsi, kuchotsa hydraulic slag kapena payipi yotumiza mpweya.

Schematic
Kugwiritsa ntchito
▪ Vavu ya eccentric hemispherical valve body imagwiritsa ntchito valavu ya eccentric, mpira wa eccentric ndi mpando wa valve.Ndodo ya valve ikazungulira, imangokhazikika panjira wamba.Kutsekedwa kowonjezereka, kumakhala kolimba kwambiri pakutseka, kuti akwaniritse cholinga cha kusindikiza bwino.
▪ Mpira wa valavu umasiyanitsidwa kotheratu ndi mpando wa valve, umene umathetsa kuvala kwa mphete yosindikizira ndikugonjetsa vuto loti mpando wa valve wachikhalidwe ndi malo osindikizira a mpira nthawi zonse amavala.Zinthu zopanda zitsulo zotanuka zimayikidwa pampando wachitsulo, ndipo pamwamba pazitsulo za mpando wa valve zimatetezedwa bwino.
▪ Valavu iyi ndiyoyenera makamaka kumakampani azitsulo, mafakitale a aluminiyamu, CHIKWANGWANI, tinthu tating'onoting'ono tating'onoting'ono, zamkati, phulusa la malasha, gasi la petroleum ndi media zina.
