Wax soo saar xirfadeed ASME BS1873 bir ah oo laga sameeyay fiilooyinka adduunka oo dhan joojiya waalka bixiyaha warshadda Shiinaha
Waa maxay waalka adduunka ee BS1873?
waalka adduunka ee BS1873
waa mid ka mid ah naqshadaha ugu caansan ee waalka adduunka, ee loogu talagalay nidaamka Mareykanka iyo API. Dhexroorka gudaha, agabka, wejiga, dhumucda derbiga, heerkulka cadaadiska, waxaa lagu qeexay ASME B16.34.
Shaki kuma jiro inwaalka adduunka ee BS1873waxaa sidoo kale loo isticmaali karaa ujeeddooyin ceejin ah. Jidhyo badan oo waalka ah oo hal kursi ku jira ayaa adeegsada qafis ama qaab-dhismeed qaab-haye ah si ay u ilaaliyaan giraanta kursiga, u bixiyaan hagitaan ku-xidhka waalka, iyo inay bixiyaan hab lagu dhiso astaamo gaar ah oo socodka waalka ah. Waxa kale oo si fudud loogu beddeli karaa qaybaha goynta si loo beddelo astaamaha socodka ama loo bixiyo awood yarsocodka, yaraynta buuqa, ama yaraynta ama baabi'inta cavitation-ka.
Qaababka Jirka ee ASME Globe Valve, waxaa jira saddex qaab oo jirka ah oo aasaasi ah ama naqshado loogu talagalay waalka Globe, kuwaas oo kala ah:
- 1). Qaabka Caadiga ah (sidoo kale loo yaqaan Qaabka Tee ama T - Qaabka ama Z - Qaabka)
- 2). Qaabka Xagasha
- 3). Qaab-dhismeedka Ubucda ah (oo sidoo kale loo yaqaan Qaabka Wye ama Qaabka Y)
Mabda'a Shaqada eewaalka adduunka ee BS1873
Waalka adduunka wuxuu ka kooban yahay saxan la dhaqaajin karo iyo kursi giraan ah oo taagan oo ku yaal jir wareegsan. Kursiga waalka adduunka wuxuu ku yaal bartamaha oo barbar socda tuubada, furitaanka kursigana waxaa lagu xiraa saxanka. Marka giraangiraha gacanta lagu wareejiyo gacanta ama hawl-wadeen, dhaqdhaqaaqa saxanka waxaa lagu xakameeyaa (hoos loo dhigaa ama kor loo qaadaa) iyadoo la adeegsanayo jirridda waalka. Marka saxanka waalka adduunka uu ku fadhiisto giraanta kursiga, socodka gebi ahaanba waa la joojiyaa.
Muuqaalka ugu muhiimsan ee waalka adduunka BS1873
- 1). Awoodaha shaabadaynta wanaagsan
- 2). Masaafada safarka gaaban ee saxanka (istaroogga) ee u dhaxaysa boosaska furan iyo kuwa xiran,waalka adduunka ASMEwaa kuwo ku habboon haddii waalka si joogto ah loo furo oo loo xidho;
- 3).Waalka adduunka ee ASME waxaa loo isticmaali karaa sidii waalka joojinta hubinta iyadoo wax laga beddelayo naqshadda si yar.
- 4).THalkan waxaa ku yaal noocyo kala duwan oo karti ah oo laga heli karo qaababka jirka ee tee, Wye, iyo xagasha.
