Wogulitsa ma valve a chipata cha mainchesi 64 ku China wopanga fakitale yapamwamba kwambiri
Kodi valavu ya chipata cha mainchesi 64 ndi chiyani?
Valavu ya chipata cha mainchesi 64, 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.Yapangidwanso ndikupangidwa motsatira muyezo wa American API600, ASME B16.34, yolumikizidwa kumapeto kwa ASME B 16.5, ndipo yayesedwa motsatira API598, ili ndi ntchito yapadera komanso yoletsedwa yotulutsa kapena kuletsa kuyenda kwa mitundu yosiyanasiyana yamadzimadzi m'mapaipi.
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
Zinthu zazikulu za valavu ya chipata cha mainchesi 64
Zinthu Zazikulu
- 1) Kukula kwakukulu mpaka 72" (DN1800), ndi kuthamanga kwambiri kwa ntchito mpaka 2500lbs
- 2) Wedge yosinthasintha yokhala ndi stem-wedge yocheperako pakati, mu CA15 yolimba (13Cr) kapena yolimba ndi 13Cr, SS 316, Monel kapena Stellite Gr.6. Wedge imaphwanyidwa ndikulumikizidwa ku galasi ndipo imawongoleredwa mwamphamvu kuti isakokedwe ndi kuwonongeka kwa mipando.
- 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.
- 7) Nkhope ya mpando ya Stellite Gr.6 yolimba, yophwanyika ndikuyiyika pagalasi.Chophimba cha CF8M cholimba cha Stellite chimapezekanso ngati mungafune.
