IValve yebhola yeWeld epheleleyo
Yintoni iValve yeBhola yeWeld egcweleyo?
Ivalve yebhola yenye yezona zivalo zidumileyo kumashishini ahlukeneyoIimbonakalonjengokumelana nolwelo oluncinci, umjelo wokuhamba ogudileyo, ukuvulwa nokuvala ngokukhawuleza, kunye nolawulo oluzenzekelayo oluzenzekelayo, ivalve yebhola isetyenziswe ngokubanzi.Kodwa isihlalo okanye iivalve zebhola eziqhelekileyo zenziwe nge-PTFE kunye nezinye izinto ezingezizo zetsimbi. izixhobo, iivalvu eziqhelekileyo azinakusetyenziswa phantsi kwemeko yenkonzo yobushushu obuphezulu okanye ukumelana nokunxiba.
Ke ngoko, uluhlu lweendlela ezintsha zokuziqhelanisal iivalve zebhola ezihleli ngentsimbibabeiphuhlisiwe, 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 ze-Full Weld Ball Valve?
1.Advanced Ball kunye 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 ezilungileyo zokunxiba kunye nefuthe elixhathisayo.
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.
4. Ibhlokhi ephindwe kabini kunye ne-Bleed (i-Metal ehleli kwi-Trunnion Ball valve)
Ivalve yebhola yentsimbi ehleliyo idla ngokuthatha isakhelo sokutywina phambi kwebhola.Xa ivalve ivaliwe kwaye umngxuma ophakathi ukhutshiwe ivelufa yokukhupha, izihlalo eziphezulu kunye nezisezantsi ziya kuvala ngokuzimeleyo ulwelo kwindawo yokungena kunye nokuphuma ukuze kufezekiswe umsebenzi webhloko ephindwe kabini.
Ivalve yentsimbi ehleli phantsi kwebhola edadayo idla ngokuthatha isakhi sokutywina emva kwebhola.Indlela yokuhamba iya kuphawulwa kumzimba wevalve yebhola unidirectional ukutywinwa kokunye.
5. Ukusebenza okuthembekileyo kokutywinwa
Itekhnoloji eyodwa yokusila ibhola yamkelwe, 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 zentsimbi ezihleliyo kuhlangabezana neemfuno zenqanaba IV le-ANSI B16.104.

uMboniso weMveliso:
Ukusetyenziswa kweValve ye-Weld Ball epheleleyo
Isetyenziselwa ntoni iValve yeBhola yeMetal ehleliyo?
Iivalve yentsimbi ehleli phantsiisetyenziselwa ngokubanzi ukunqumla okanye ukudibanisa imidiya kwimibhobho eyahlukeneyo, i-petroleum, imboni yeekhemikhali, amandla ombane, i-metallurgy, imboni yokukhanya.Ilungele iimeko zenkonzo enzima equlethe iigranuli eziqinileyo, i-slurry, umgubo wamalahle, i-cinder njl.
