Waa maxay Throttling 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.
Qulqulka globe valve waa mid ka mid ah naqshadaha ugu caansan ee valves globe, ee nidaamka US iyo API. 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 eeQulqulka globe valvewaxaa si togan u xakameyn kara jirid la maroojiyay.Awoodda daboolida eeQulqulka 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,Qulqulka globe valveWay 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.
ahQulqulka globe valveWaxa 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.
Tilmaamaha ugu muhiimsan ee waalka Throttling globe
- 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-noolaynta kuraasta, ujeedooyin kala duwan.
