Waa maxay BS1873 globe valve?
BS1873 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.
ahBS1873 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.
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 eeBS1873 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.
Muuqaalka ugu muhiimsan ee BS1873 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.
