Valavu ya chipata cha inchi 72 ya mafakitale ku China Wopanga fakitale
Kodi valavu ya chipata cha mainchesi 72 ndi chiyani?
Valavu ya chipata cha mainchesi 72, ntchito yayikulu komanso yaukadaulo yofanana ndi ma valve wamba a API600 wedge gate.Valavu ya chipata cha wedge imatha kutsegulidwa kwathunthu komanso kutsekedwa kwathunthu ndipo singasinthidwe ndikukankhidwa. Valavu ya chipata idapangidwa kuti igwiritsidwe ntchito potseguka kwathunthu kapena kutsekedwa kwathunthu, chifukwa chifukwa cha mawonekedwe a zotchingira zake zomwe zili ndi mawonekedwe a wedge, ngati ikadagwiritsidwa ntchito pang'ono, padzakhala kutayika kwakukulu kwa mphamvu ndipo pamwamba pa kutsekapo padzawonongeka madzi akakhudzidwa.
koma pamafunika mphamvu zambiri kuti apange ma valve a API600 akuluakulu.
- 1) dongosolo lopangira: seti yonse ya mapangidwe akuluakulu a thupi lonse, bonnet, wedge etc.
- 2) zida: kulondola kwambiri makina ofukula, kuboola, opera a mainchesi akuluakulu.
- 3) akatswiri aukadaulo ndi antchito aluso: n'zovuta kwambiri kupanga ma valve akuluakulu a chipata.
kotero pali mafakitale ochepera 10 omwe angathe kupangaMa valve akuluakulu a API600mpaka mainchesi 72. Tikuyimira m'modzi mwa opanga ma valve akuluakulu ku China, Nantong High ndi middel pressure valve co, ltd (TH), chifukwa cha ma valve awo akuluakulu a chipata, ma valve a chipata champhamvu kwambiri.
Zinthu zazikulu za valavu ya chipata cha mainchesi 72
Zinthu Zazikulu
- 3) Kukongoletsa konsekonse: Kukongoletsa kwa API 1 (13Cr), kukongoletsa 5 (Stellite Gr.6 yoyang'ana pa wedge ndi mpando) ndi kukongoletsa 8 (Stellite Gr.6 yoyang'ana pa mpando) kulipo. Ndipo manambala ena okongoletsa kutengera zida zomwe zasankhidwa.
- 4) Flanges: ASME B16.5 ndi ASME B16.47 ya 28"-72"
- 5) Kusindikiza mbali ziwiri
- 6) Kukana kuyenda pang'ono komanso kutayika kwa kuthamanga kwa mpweya, chifukwa cha njira yolunjika yoyendera madzi komanso wedge yotseguka kwathunthu.
- 7) Nkhope ya mpando ya Stellite Gr.6 yolimba, yophwanyika ndikuyiyika pagalasi.Chophimba cha CF8M cholimba cha Stellite chimapezekanso ngati mungafune.
