ASME Globe Valve
Waa maxay ASME Globe Valve?
Globe valves waa dhaqaaqa toosan ee xidhidhiyaha ee loo isticmaalo in lagu bilaabo, la joojiyo ama lagu xakameeyo socodka iyada oo la adeegsanayo xubin xidhitaan oo loo yaqaan saxan.Kursiga waalka globe wuxuu ku yaalaa dhexda wuxuuna barbar socdaa tuubada, furitaanka fadhigana wuxuu ku xiran yahay saxan ama fur.Furitaanka kursigu wuxuu isu beddelaa si siman marka loo eego safarka saxanka kaas oo ku habboon waajibaadka ku lug leh nidaaminta socodka.Gawaarida Globe ayaa ah kuwa ugu habboon oo si ballaaran loo isticmaalo si loo xakameeyo ama loo joojiyo qulqulka dareeraha ama gaasta ee tuubada si loo xakameeyo loona xakameeyo socodka dareeraha waxaana guud ahaan lagu shaqeeyaa tuubooyin yar yar.
ASME Globe valvewaa mid ka mid ah naqshadaha ugu caansan ee valves globe, ee US iyo API system. dhexroorka gudaha, walxaha, wejiga wejiga, dhumucda derbiga, heerkulka cadaadiska, waxaa lagu qeexay ASME B16.34.
Intaa waxaa dheer, ku xiran tahay design kursiga iyo disc, load fadhiga eeASME globe valveswaxaa si togan u xakameyn kara jirid la maroojiyay.Awoodda daboolida eeASME globe valveaad ayuu u sarreeyaa.Waxaa loo isticmaali karaa shaqada bannaanka ah.Sababtoo ah masaafada safarka gaaban ee saxanka u dhexeeya meelaha furan iyo kuwa xiran,ASME globe valvesWay ku fiican yihiin haddii tuubada la furo oo la xiro si joogto ah.Sidaa darteed, globe valves waxaa loo isticmaali karaa hawlo kala duwan oo kala duwan.
ahASME Globe valvesWaxa kale oo loo isticmaali karaa ujeedooyinka ceejinta.waxa kale oo si fudud wax looga beddeli karaa iyadoo la beddelo qaybaha jar si loo beddelo sifada socodka ama loo bixiyo awood-hoosaysiqulqulka, dhimista qaylada, ama dhimista ama baabi'inta cavitation.
ASME Globe Valve Body Patterns, waxaa jira saddex qaab oo jirka aasaasiga ah ama nashqadaha loogu talagalay valves Globe, oo kala ah:
- 1) Habka caadiga ah (sidoo kale loo yaqaan Tee Pattern ama T - Qaabka ama Z - Qaabka)
- 2)Qaabka xagal
- 3) Habka Oblique (sidoo kale loo yaqaan Wye Pattern ama Y - Qaabka)
Mabda'a shaqada eeASME Globe Valve
Waalka globe waxa uu ka kooban yahay saxan la dhaqaajin karo iyo kursi giraan taagan oo ku yaala jidh wareegsan.Kursiga waalka globe wuxuu ku yaalaa dhexda wuxuuna barbar socdaa tuubada, furitaanka fadhigana wuxuu ku xiran yahay saxanka.marka giraangiraha gacantu uu ku wareego gacanta ama jileeyaha, dhaqdhaqaaqa saxanka ayaa la kontaroolaa (hoos loo dhigaa ama kor loo qaadaa) iyada oo la adeegsanayo jirridda waalka.Marka saxanka globe valve uu ku fadhiisto giraanta kursiga, socodka gabi ahaanba waa la joojiyaa.
Tilmaamaha ugu muhiimsan ee ASME Globe valve
- 1) .Awoodda xidhidhiyaha wanaagsan
- 2) Masaafada gaaban ee saxanka (stroke) inta u dhaxaysa meelaha furan iyo kuwa xiran,ASME globe valvesway ku fiican yihiin haddii ay qasab tahay in la furo oo la xidho si joogta ah;
- 3).ASME globe valve waxaa loo isticmaali karaa sidii waalka joogsiga joogsiga iyadoo wax yar laga beddelayo naqshadda.
- 4).THalkan waxaa ku yaal awoodo kala duwan oo kala duwan sida laga heli karo tee, Wye, iyo qaababka jirka xagasha.
- 5).Makiinadda fudud iyo dib-u-soo-nooleynta kuraasta, ujeedooyin kala duwan.
- 6).Dhexdhexaad ama karti wanaagsan oo xoqid ah, adoo wax ka beddelaya qaabka kursiga iyo saxanka.
- 7).Bshaabada ellows waa la heli karaa marka la codsado.
