DIN3202 Cast Steel Gate Valve
Waalka albaabka waxa loola jeedaa waalka qaybtiisa xidhitaankeedu (albaabka) u dhaqaaqo dhinaca toosan ee xariiqda dhexe ee kanaalka.Albaabka albaabka waxaa inta badan loo isticmaalaa goynta dhuumaha.Waalka iridda birta been abuurka ah waa waalka si weyn loo isticmaalo.Guud ahaan waxaa loo isticmaalaa in lagu gooyo qalabka leh dhexroorka DN ≥ 50mm, mararka qaarkood albaabka albaabka waxaa sidoo kale loo isticmaalaa in lagu gooyo qalabka leh dhexroor yar.Waalka albaabka, sida waalka-hooseeya, ayaa aad u badan.
Gate valve sifooyinka
Waxqabadka xidhidhiyaha wanaagsan, caabbinta dareeraha yar iyo waxqabadka qawaaniinta qaarkood;Si kastaba ha ahaatee, waxay leedahay cabbir weyn, qaab-dhismeed adag, farsamayn adag, xidhid fudud oo dabool ah, dayactir adag iyo waqti dheer oo furitaan iyo xidhidh.Waxay ku habboon tahay samaynta valves dhexroor weyn.Marka lagu daro uumiga, saliidda iyo warbaahinta kale, waxay sidoo kale ku habboon tahay warbaahinta ka kooban xayndaabyada granular iyo viscosity sare, iyo sidoo kale valves ee hawo-qaadista iyo nidaamyada faakuumka hooseeya.
