I-Turbine Inlet Valve ye-Butterfly Valve, i-Spherical Valve kanye ne-Gate Valve
Ukuze ugweme ingozi ekukhuleni, ukukhuphuka noma ukucisha isikhathi eside, i-valve enkulu yokungena kufanele ifakwe phambi kwe-turbine.
Ngokuvamile kuyadingeka ukuthi kufakwe ivalvu ngaphambi kwe-turbine lapho ipayipi lensimbi lifakwe amagatsha ukuze linikeze amanzi, futhi amayunithi amaningana noma ipayipi lokuphambukisa umfutho lide kakhulu.
Umsebenzi:
1. Vimbela ukugeleza kwamanzi ngesikhathi sokuhlolwa nokulungiswa kabusha kwe-turbine;
2. Nciphisa ukuvuza kwamanzi kweyunithi lapho umshini wokushisa umoya uvaliwe;
3. Vala i-valve yokungena ukuze uvimbele iyunithi ukuthi ingaphumi lapho ivane yomhlahlandlela ihluleka.
Umkhiqizo Isingeniso
Ama-valve e-turbine inlet afaka izinhlobo ezintathu:
1. I-Butterfly valve ifaneleka kuFrancis turbines.
2. I-valve eyindilinga ifanele amayunithi ohlobo lwe-high-head impulse type
3. I-valve yesango isetshenziswa ngezindleko eziphansi, futhi ikakhulukazi kumayunithi amancane
Kunezindlela ezine zokusebenza: i-manual, kagesi, ingcindezi kawoyela kanye nomfutho wamanzi.
I-valve ye-butterfly yesando esindayo kanye ne-valve eyindilinga kusetshenziswa umfutho kawoyela noma umfutho wamanzi lapho zivuleka, futhi zithembele esando esindayo ukuze sivale ngokuzenzakalelayo lapho zivalwa. Isenzo sithembekile futhi isikhathi sokuvala siyalungiseka. Isetshenziswa kabanzi njengamanje.
