Soo saaraha Shiinaha/Iibiyaha ATEX Waalka kubbadda la shahaadiyay
Waa maxay waalka kubbadda ATEX?
Ball valve waa mid ka mid ah kuwa ugu caansan ee warshadaha kala duwanAstaamahasida iska caabin dareere yar, channel socodka siman, furitaanka degdega ah iyo xidhitaan, iyo si fudud u kontorool toos ah, waalka kubada ayaa si weyn loo isticmaalay.
Sidaa darteed, taxane ah practica style cusubl ATEX kubbadda cagta ahaayeenhorumaray,iyoayaa si weyn looga codsadey shidaalka, warshadaha kiimikada, tamarta korontada, biraha, warshadaha iftiinka iwm
Birta ilaa birta kursiga kubbadda cagta ayaa leh ma aha oo kaliya faa'iidooyinka kala duwan ee valves kubbadda warshadaha ee caadiga ah, laakiin sidoo kale sifooyin gaar ah oo heer sare ah ee adkaysiga kulaylka, gaar ahaan marka shaabadda jilicsan aan la isticmaali karin, sida gudbinta dhuumaha dhexdhexaadka ah oo leh boodh sare oo jilicsan, slurry ,iyo arrimo shisheeye oo adag oo isku dhafan.
Astaamaha ugu muhiimsan ee waalka kubbadda ATEX?
1.Tignoolajiyada Adkeynta Kubada iyo Kursiga Sare
Shaabadeynta waxaa lagu sameeyaa birta si ay u cunaan inta u dhaxaysa kubbadda iyo kursiga birta ee valves kubbadda. Sida laga soo xigtay shuruudaha adeegga kala duwan iyo shuruudaha isticmaalayaasha, kubbadda horumarsan ee kala duwan iyo tiknoolajiyada adkaynta kursiga ayaa la qaadan karaa, oo ay ku jiraan daahan HVOF, alxanka buufinta nickel-base, Alxanka buufinta sare ee nikkel, kiis cobalt adag alxanka buufinta, iwm. Guud ahaan kubbadda iyo engegnaanta dusha sare waxay gaari karaan HRC55-60 oo leh qiimaha ugu badan ee HRC70. iyo sida caadiga ah, iska caabbinta kulaylka ee alaabta wejiga xirmaysa waxay noqon kartaa 540 ° C , oo leh qiimaha ugu badan ee 980 ° C.Maaddada daboolka ah ayaa sidoo kale leh xirmo wanaagsan oo u adkaysta iyo waxqabadyada adkaysiga u leh.
2. Furitaanka iyo xidhitaanka Valve dabacsan
Marka la eego xaaladda adeegga heerkulka sare, kubbadda iyo kursigu aad bay u balaadhin doonaan sababtoo ah balaadhinta kulaylka, iyo qulqulka ayaa kordhi doona oo waalka lama furi karo. heerkulka sare hoostiisa waxaa nuugi kara guga saxanka ama guga.Waxaana la hubiyaa in waalka si dabacsan loo furi doono oo lagu xidhi doono heerkul sare iyada oo aan aad loo balaadhin.
3. Naqshadaynta Qaab-dhismeedka Dab-damiska
In birta in qaab-dhismeedka biraha ee waalka, gasket waa ahama + graphite dabacsan iyo baakaduhu waa graphite dabacsan. Sidaa darteed, shaabadeynta lagu kalsoonaan karo ee waalka waa la xaqiijin karaa xitaa haddii ay dhacdo dab.
5. Waxqabadka Shaabadeynta lagu kalsoonaan karo
Tiknoolajiyada wax lagu shiido kubbada gaarka ah ayaa la ansixiyay,iyada oo loo marayo wareegtada kubbadda iyo shiidka er ee boosaska kala duwan. dusha kubbadda waxay gaari doontaa wareegyo sare iyo ganaax. Saamaynta piston ee kursiga waalka waxaa loo qaabeeyey si macquul ah, kaas oo garwaaqsada cadaadiska sare ee shaabadeynta dareerayaasha laftiisa, cidhiidhi gelinta birta ee kubaddu waxay buuxisaa shuruudaha heerka IV ee ANSI B16.104.
