Mabda'a Shaqada ee a3-Jidka Ball Valve
Waalka kubbadda 3-geesoodka ah wuxuu ka kooban yahay kubad godan oo wareegaysa oo leh hal ama laba dekedood (godad) iyo saddex isku xir oo tuubooyin ah. Marka kubbadda gacanta lagu wareejiyo ama loo maro hawl-wadeen, waddada socodka ayaa loo wareejinayaa. Iyada oo ku xidhan naqshadda waalka, waxay samayn kartaa:
- Socodka leexintainta u dhaxaysa laba meelood oo kala duwan.
- Dareeraha isku qaslaga bilaabo laba irdood oo gala hal irdood.
- Dami socodkagebi ahaanba.
Booska kubbadu wuxuu go'aamiyaa jihada socodka. Tusaale ahaan, leexashada 90-degree waxay ka beddeli kartaa socodka hal deked una wareejin kartaa mid kale, halka leexashada 180-degree ay xannibi karto dhammaan socodka.
