Umenzi/Umthengisi waseTshayina i-ATEX Certified ball valve
Yintoni ivalvu yebhola ye-ATEX?
Ivalvu yebhola yenye yezona valve zidumileyo kwimizi-mveliso eyahlukeneyo.IimbonakaloNjengoko incinci indlela yokumelana nolwelo, itshaneli yokuhamba kakuhle, ukuvulwa nokuvalwa ngokukhawuleza, kunye nolawulo oluzenzekelayo olulula, ivalvu yebhola isetyenziswa kakhulu.
Ngoko ke, uthotho lweendlela ezintsha zokwenza izintoIivalvu zebhola ze-l ATEX babeyaphuhliswa, kwayezisetyenziswe kakhulu kwi-petroleum, kushishino lweekhemikhali, kumandla ombane, kwi-metallurgy, kushishino lokukhanya njl.njl.
Ivalvu yebhola yesihlalo sentsimbi ukusuka kwisinyithi ayinazo nje kuphela iingenelo ezahlukeneyo zeevalvu zebhola zemizi-mveliso eziqhelekileyo, kodwa ikwanazo neempawu ezikhethekileyo nezibalaseleyo zokuqina kobushushu, ingakumbi xa isitywino esithambileyo singasetyenziswa, njengokuhambisa imibhobho yesixhobo esinothuli oluphezulu lokukhuhlana, ulusu, kunye nomxube wezinto zangaphandle eziqinileyo.
Iimpawu eziphambili zevalvu yebhola ye-ATEX?
1. Iteknoloji yokuqinisa ibhola kunye nesihlalo esiphambili
Ukutywinwa kwenziwa ngentsimbi ukuze kutyiwe phakathi kwebhola kunye nesihlalo sentsimbi seevalvu zebhola. Ngokweemeko ezahlukeneyo zenkonzo kunye neemfuno zabasebenzisi, iindlela ezahlukeneyo zokuqinisa ibhola kunye nezihlalo zingasetyenziswa, kubandakanya i-HVOF coating, i-nickel-base alloy spray welding, i-nickel alloy spray welding ephezulu, i-cobalt case hard alloy spray welding, njl. Ngokubanzi ubunzima bebhola kunye nomphezulu wesihlalo bunokufikelela kwi-HRC55-60 ngexabiso eliphezulu le-HRC70. kwaye ngokwesiqhelo, ukumelana nobushushu kwezinto zobuso bokuvala kungaba yi-540°C, ngexabiso eliphezulu le-980°C. Izinto zobuso bokuvala zikwanazo neempawu ezintle zokumelana nokuguguleka kunye nokumelana nempembelelo.
2. Ukuvulwa nokuvalwa kweValve eguquguqukayo
Phantsi kwemeko yenkonzo yobushushu obuphezulu, ibhola kunye nesihlalo ziya kwanda kakhulu ngenxa yokwanda kobushushu, kwaye i-torque iya kwanda kwaye ivalvu ayinakuvulwa, ivalvu yebhola isebenzisa isakhiwo sokutywina sediski okanye ispring esithwele i-spring ukuze ukwanda kobushushu kwamalungu angaphantsi kobushushu obuphezulu kungene kwispring okanye ispring yediski. Kwaye kuqinisekiswa ukuba ivalvu iya kuvulwa kwaye ivalwe ngokulula phantsi kobushushu obuphezulu ngaphandle kokwanda kakhulu.
3. Uyilo lweSakhiwo esingatshiyo
Kwisakhiwo sevalvu ukusuka kwintsimbi ukuya kwisinyithi, i-gasket yintsimbi engatyiwayo + i-graphite eguquguqukayo kwaye ukupakisha yi-graphite eguquguqukayo. Ke ngoko, ukuvalwa okuthembekileyo kwevalvu kunokuqinisekiswa nokuba kutsha.
5. Ukusebenza Kokutywina Okuthembekileyo
Itekhnoloji yokusila ibhola eyahlukileyo iyasetyenziswa, ngokujikeleza ibhola kunye ne-grinder kwiindawo ezahlukeneyo. Umphezulu webhola uya kufezekisa ukujikeleza okuphezulu kunye nokuqina. Ukutywinwa koxinzelelo oluphantsi kwesihlalo sevalvu kwenziwa ngokuqiniswa kwangaphambili kwentwasahlobo. Ukongeza, isiphumo sepiston sesihlalo sevalvu senziwe ngokufanelekileyo, esenza ukutywinwa koxinzelelo oluphezulu ngamanzi ngokwawo, ukuqina kweevalvu zebhola ezihleli ngentsimbi kuyahlangabezana neemfuno zenqanaba IV le-ANSI B16.104.

Ukusetyenziswa kwevalvu yebhola ye-ATEX
Isetyenziselwa ntoni ivalvu yebhola ye-ATEX?
Ivalvu yebhola ye-ATEX isetyenziswa kakhulu ukusika okanye ukudibanisa izixhobo zombane kwiipayipi ezahlukeneyo, ipetroli, ishishini leekhemikhali, amandla ombane, isinyithi, ishishini lokukhanya. Ifanelekile kwiimeko ezinzima zenkonzo equlethe iigranules eziqinileyo, i-slurry, umgubo wamalahle, i-cinder njl.
