E laola mocheso o fokotsang phallo ea metsi a mocheso le valve e fokotsang khatello bakeng sa overpass e phahameng ea turbine ea mouoane. Ka boemo ba ts'ebetso ea khatello e phahameng le phapang e kholo ea khatello, e amohela mekhoa e mengata ea mehato e mengata ho thibela ho hlaha ha cavitation le flash evaporation.

  1. Valve ke sebopeho sa angular mme tataiso ea phallo e mahareng ke mofuta o koalang oa phallo (e tšekaletseng e kenang le e tlase e tsoang).
  2. Ho amohela sebopeho sa tšepe se entsoeng ka matla a phahameng, 'mele oa valve le bonnet li ka fihlela litlhoko tsa matla tlas'a mocheso o phahameng le khatello hantle.
  3. Ka sebopeho sa mofuta oa sekoti se nang le mehato e mengata, mokokotlo oa valve o lemoha mehato e mengata ea ho fokotsa khatello. Mohato o mong le o mong oa throttle o etsa hore mokelikeli o kopane 'me ho phethoha ka lehlakoreng le letona la 90 ° ho hlokomela phokotso ea khatello. Kaha khatello e ka holim'a khatello ea saturation ka mor'a mohato o mong le o mong oa ho fokotsa khatello, ha ho na cavitation le evaporation ea flash e hlahisoang nakong ea ho fokotsa khatello; ho thothomela le lerata di laolwa ka katleho.
  4. E sebelisa moralo o tšoanang oa sekoaelo sa phallo ho thibela phallo ea mokelikeli hore e se ke ea hlahisa matla a khelohang mokokotlong oa valve le ho qoba ho abrasion e le 'ngoe.
  5. 'Mele oa li-valve le bonnet li sebelisa sebopeho sa ho itšeha ka khatello.
  6. Ka likarolo tse lekanang tsa phallo ea liperesente, e ka laola phallo e mahareng ho fihlela ts'ebetso e ntle ea taolo ka nepo.
  7. Valve e na le hydraulic actuator ho hlokomela ts'ebetso e potlakileng le mesebetsi ea taolo.
