I-valve yepulaki ehlezi ensimbi Egcotshwe ipulaki Umkhiqizi wefektri wase-China Umkhiqizi
Iyini i-Metal ehlezi ipulaki valve?
I-valve yepulaki ehlezi ngensimbi iqukethe umgodi phakathi kwepulaki eduze kwe-eksisi yayo.Lesi sikhala sivalwe ngezansi futhi sifakwe umjovo we-sealant phezulu.I-sealant ijova emgodini, futhi i-valve yokuhlola engezansi komjovo ivimbela i-sealant ukuthi ingagelezi ibheke emuva.I-sealant iphuma phakathi nendawo ngezimbobo ze-radial iye ku-lubricant grooves enwebeka ngobude bendawo yokuhlala yepulaki.
Ukuze unciphise i-torque yama-valve epulaki agcotshiwe esihlalo sensimbi esivamile,I-valve yepulaki ehlezi ngensimbiziyaqanjwa futhi zisetshenziswa kabanzi.Ngaphezu kwezici zama-valve epulaki ahlanganisiwe kawoyela ajwayelekile, ama-valve epulaki alinganiswe ngomfutho nawo anezici ezilandelayo:
- 1. Lapho i-valve ivuliwe, ingcindezi ekamelweni elingezansi lomzimba we-valve ilingana nokucindezela okuphakathi epayipini.Amafutha okuvala anomfutho ophezulu ekamelweni eliphezulu abangela ukuba umzimba wepulaki uphushelwe phansi, futhi kuvele igebe elincane phakathi kwekhoni yepulaki nendawo yokuvala yomzimba we-valve, i-torque yomzimba wepulaki ezungezayo iyancipha ngempumelelo.
- 2. Ezimweni zokushisa eziphakeme, ukunwetshwa okushisayo kwepulaki kungathathwa ngokukhuphuka nokuwa kwayo.I-valve yepulaki egcotshwe ngamafutha, nakuba ukusetshenziswa kokugcoba uwoyela kunganciphisa ngokufanelekile itorque yokuvula nokuvala, kodwa kungase kudale ukungcoliswa kwendawo.Ngakho-ke, i-lubricant evaliwe ikhethiwe ngezimo zangempela zokusebenza.
Izici eziyinhloko ze-Metal ehlezi ipulaki valve
Izici nezinzuzo zeI-valve yepulaki ehlezi ngensimbi
- I-1.Umkhiqizo unesakhiwo esinengqondo, ukubekwa uphawu okuthembekile, ukusebenza okuhle kakhulu nokubukeka okuhle.
- 2.Inokwakheka kwengcindezi elinganiselayo ye-flip-clip kanye nokusebenza kokukhanya kokuvula/ukuvala.
- 3.Izinto ezisetshenziswayo zezingxenye kanye nosayizi bama-flange zingahlelwa ngokufanele ngokuvumelana nesimo sangempela sokusebenza sezidingo zamakhasimende, ukuze kuhlangatshezwane nezidingo ezihlukahlukene zobunjiniyela.

Izicelo ze-Metal ehlezi ipulaki valve
I-valve yepulaki ehlezi ngensimbiisetshenziswa kabanzi ezimbonini ezihlukahlukene ezifana ne-petroleum, imboni yamakhemikhali, ikhemisi, umanyolo wamakhemikhali, imboni yamandla njll. Isetshenziswa ngaphansi kwengcindezi ebizwa ngokuthi CLASS150-1500LBS, futhi isebenza ekushiseni kuka -40 ~ 450 ° C, Amanzi, Igesi, I-Steam kanye Amafutha njll.
