I-Flange Eshiselwe Ngokugcwele I-Ball Valve
Izici ezijwayelekile ze-flange ama-valve ebhola ashiselwe ngokugcwele
1) ububanzi: DN15 ~ 1000.
2) ingcindezi: PN 16 ~ 40.
3) izinga lokushisa lokusebenza: – 29 ℃ ~ + 200 ℃
4) i-gas pipeline welding ball valve adaption medium: i-petroleum/uphethiloli, igesi yemvelo ewuketshezi/i-liquefied petroleum gas, i-petrochemical, imboni yensimbi, ipayipi lokushisisa, njll.
5) Imodi yokusebenza kwe-valve ye-gas pipeline welding ibhola: isibambo, igiya (eqondile/evundlile), ugesi, i-turbine.
I-Flange eshiselwe ngokuphelele impahla ye-valve yebhola
1) umzimba valve: carbon steel ST37.0, a106-b;20 # steel
2) indawo: insimbi engagqwali 304 noma 316.
3) Isiqu: 2Kr13.
4) i-valve stem seal: yonke i-fluorine njengeglue.
5) uphawu lwebhola: RTFE (PTFE+C)
I-Flange egcwele ukusebenza kwe-valve yebhola ye-welding
2 ukuvuza.Umzimba we-valve ushiselwe, ngakho-ke i-valve ilula futhi kulula ukuyifaka.Umshini wokulungisa ukufakwa, ulula kakhulu, isibambo singasuswa, ukubuyisela emuva ukufakwa.
2) : ngoba isihlalo senziwe nge-carbon fibre eqinisiwe indandatho ye-teflon seal kanye ne-disc spring, ngakho-ke ikhono lokuzivumelanisa nokushintsha kwengcindezi kanye nezinga lokushisa, isichasiselo sokucindezela kanye nobubanzi bokushisa ngeke kukhiqize noma yikuphi ukugeleza nokushelela.
I-3) : inqubo ye-machining yebhola ine-detector yekhompyutha ethuthukisiwe ukuze ilandele futhi ibone, ngakho-ke ukunemba kwebhola kuphezulu.
4) : njengoba impahla yomzimba ifana nempahla yepayipi, ngeke kube nokucindezeleka okungalingani futhi akukho ukuguqulwa ngenxa yokuzamazama komhlaba kanye nemoto edlula emhlabathini.Ipayipi liyamelana nokuguga.
5): i-welding ephelele ehlanganisiwe, ububanzi obulinganayo kanye neshaneli yobubanzi obuguquguqukayo, enebhola elingaguquki nebhola elintantayo, uhlelo lokuvala uphawu lwe-piston kabili, umjovo othomathikhi wokuthwala uhlobo lwe-sealant.
6) : ukuze kuvinjwe i-electrostatic, isiqu kanye ne-sphere kanye ne-valve stem kanye nebhokisi lokupakisha elinebhola nesiphethu ngokulandelana, phakathi kwe-conductive kungagcina zonke izingxenye ze-valve nomzimba we-valve, ukuvumela ugesi udlule endaweni, ukukhululwa kukagesi omile.Not ukuvimbela kuphela umlilo, kodwa futhi kuvimbele ukugqwala, qaphela ukunqunywa kwesikhashana, ukuze kulungiswe ngesikhathi.
I-7) : umsebenzi we-stem we-stem kungenxa yokuthi i-valve stem ithonywa ukucindezela ngaphakathi kwe-valve, futhi ihlale ikhiqiza amandla okunqamula, ngakho-ke isiqu senzelwe ukuvimbela isakhiwo.
8) : cindezela i-thrust washer enento ephansi yokungqubuzana ukuze usunduze ukucindezela esiqwini, ukuze isiqu SEBENZE kuphela njengetorque yokudlulisela.
