Waalka kubbadda-xiro-ka-hortagga ee bamka saliidda ee Wershadaha Saliidda ee lagu sameeyay Shiinaha
Waa maxay valve-ka-hortagga kubbadda?
Ball valve waa mid ka mid ah kuwa ugu caansan ee warshadaha kala duwanAstaamahasida caabbinta dareeraha yar yar, kanaalka qulqulka siman, furitaanka degdega ah iyo xidhitaanka, iyo xakamaynta fudud ee tooska ah, valve kubbadda ayaa si weyn loo isticmaalay. Laakiin kursiga ama qalabka kubbadda caadiga ah ayaa guud ahaan laga sameeyaa PTFE iyo qalabka kale ee aan birta ahayn. Alaabooyinka, valves-ka caadiga ah looma isticmaali karo xaalad adeeg heerkul sare ama xirto caabbinta.
Sidaa darteed, taxane ah practica style cusubl Waalka kubbadda-xidhashada ahaayeenhorumaray,iyoayaa si weyn looga codsadey shidaalka, warshadaha kiimikada, tamarta korontada, biraha, warshadaha iftiinka iwm
Astaamaha ugu muhiimsan ee waalka kubbadda-xidhashada?
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.
4. Qulqulka labalaabka ah iyo Dhiig-baxa
Waalka kubbadda trunnion-ka ee birta ah ee fadhida wuxuu caadi ahaan qaataa qaab-dhismeedka daboolka ka hor kubbadda.Marka waalka la xiro oo daloolka dhexe la faaruqiyo waalka soo daaya, kuraasta kore iyo kuwa hoose waxay si madaxbannaan u xannibi doonaan dareeraha gudaha iyo meesha laga soo galo si ay u ogaadaan shaqada xannibaadda ee labanlaaban.
Waalka kubbadda sabbaynaya ee birta ah ayaa sida caadiga ah qabata qaab-dhismeedka shaabadeynta kubbadda ka dib. Jihada socodka ayaa lagu calaamadayn doonaa jidhka si loogu xidho valve valve unidirectional. Haddii lagu qeexo isticmaalayaasha dhamaadka, xidhitaanka laba jiho waa la samayn karaa.
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.
