China Manufacturer/Supplier ATEX Certified ball valve
Yintoni ivalve yebhola ye-ATEX?
Ivalve yebhola yenye yezona zivalo zidumileyo kumashishini ahlukeneyoIimbonakalonjengokumelana nolwelo oluncinci, umjelo wokuhamba ogudileyo, ukuvulwa nokuvala ngokukhawuleza, kunye nolawulo olulula oluzenzekelayo, ivalve yebhola isetyenziswe ngokubanzi.
Ke ngoko, uluhlu lweendlela ezintsha zokuziqhelanisal Iivalvu zebhola ze-ATEX babeiphuhlisiwe, kwayezisetyenziswe ngokubanzi kwi-petroleum, kushishino lweekhemikhali, amandla ombane, isinyithi, imboni yokukhanya njl
Ivalve yentsimbi ukuya kwisihlalo sentsimbi ayinazinto eziluncedo kuphela zevalvu yebhola yemveliso eqhelekileyo, kodwa ikwaneempawu ezithile nezibalaseleyo ekomeleleni kobushushu, ngakumbi xa isitywina esithambileyo singenakusetyenziswa, njengokuhanjiswa kwemibhobho ephakathi kunye nothuli olukhuhlana kakhulu, ludaka. kunye nomxube oqinileyo wemicimbi yangaphandle.
Iimpawu eziphambili zevalve yebhola ye-ATEX ?
I-1.Ibhola ePhambili kunye ne-Seat Hardening Technology
Ukutywinwa kwenziwa ngentsimbi yokutya phakathi kwebhola kunye nesihlalo sentsimbi yeevalvu zebhola.Ngokungqinelana neemeko ezahlukeneyo zenkonzo kunye neemfuno zabasebenzisi, iibhola ezahlukeneyo eziphambili kunye nobuchwepheshe bokuqina besihlalo bunokwamkelwa, kubandakanywa ukugquma kwe-HVOF, i-nickel-base-alloy spray welding, i-nickel alloy spray welding ephezulu, i-cobalt case hard alloy spray welding, njl. Ngokuqhelekileyo ibhola kunye nesihlalo sobulukhuni sobuso bunokufikelela kwi-HRC55-60 ngexabiso eliphezulu le-HRC70. , ngexabiso eliphezulu lama-980°C.Isixhobo sobuso sokutywinwa sikwanezinto ezifanelekileyo zokunxiba kunye nefuthe elichasayo.
2.Flexible Valve Ukuvula kunye Ukuvala
Ngaphantsi kwemeko yenkonzo yobushushu obuphezulu, ibhola kunye nesihlalo siya kwanda kakhulu ngenxa yokwandiswa kwe-thermal, kwaye i-torque iya kwanda kwaye ivalve ayinakuvulwa, ivalve yebhola ithatha i-disc spring okanye i-spring elayishiwe ukutywinwa kwesakhiwo ukuze ukwandiswa kwe-thermal yamacandelo. phantsi kobushushu obuphezulu bunokufunxwa yi-disc spring okanye entwasahlobo.Kwaye kuqinisekiswa ukuba i-valve iya kuvulwa ngokuguquguqukayo kwaye ivalwe phantsi kobushushu obuphezulu ngaphandle kokwandisa kakhulu.
3. Uyilo lweSakhiwo esingangenwa ngumlilo
Kwisinyithi ukuya kwisakhiwo sentsimbi yevalve, i-gasket yintsimbi ye-stainless + igraphite eguquguqukayo kwaye ukupakishwa yigraphite eguquguqukayo. Ngoko ke, ukutywinwa okuthembekileyo kwevalve kunokuqinisekiswa nokuba kukho umlilo.
5. Ukusebenza okuthembekileyo kokutywinwa
Itekhnoloji eyodwa yokusila ibhola yamkelwa, ngokujikeleziswa kwebhola kunye ne-grind er kwiindawo ezahlukeneyo. Umphezulu webhola uya kufumana ukujikeleza okuphezulu kunye nokucoleka. Ukutywinwa koxinzelelo oluphantsi lwesihlalo sevalve kufezekiswa ngentwasahlobo kwangaphambili. Impembelelo yepiston yesitulo sevalvu iyilwe ngokufanelekileyo, eqonda ukutywinwa koxinzelelo oluphezulu ngamanzi ngokwawo, Ukuqina kweevalvu zebhola ezihleliyo zihlangabezana neemfuno zenqanaba IV le-ANSI B16.104.

Intsimbi ehleli ivelufa yebhola edadayo
Iinkcukacha zobugcisa zevalve yebhola ye-ATEX ?
Iivalvu zentsimbi ezihleli phantsi, uyilo olwahlukileyo lwebhola edadayo kunye nebhola yetrunnion.
uMboniso weMveliso: ivalve yebhola yeATEX
Ukusetyenziswa kwevalve yebhola ye-ATEX
Isetyenziselwa ntoni ivalve yebhola ye-ATEX?
I-valve yebhola ye-ATEX isetyenziselwa ngokubanzi ukunqumla okanye ukudibanisa imidiya kwiipayipi ezahlukeneyo, i-petroleum, imboni yeekhemikhali, amandla ombane, i-metallurgy, imboni yokukhanya.Ilungele iimeko zenkonzo enzima equlethe iigranuli eziqinileyo, i-slurry, umgubo wamalahle, i-cinder njl.
