Li-valve tsa taolo li tataisa phallo ea mokelikeli oa hydraulic le ho laola khatello ho netefatsa ts'ebetso e boreleli le e nepahetseng ea li-cylinder, li-motor le likarolo tse ling tsa hydraulic, tse kang lisebelisoa tse metsi bakeng sa fatše le li-tipper likoloing tsa khoebo.
U ka nahana ka bona e le bahale ba sa tumang ba li-hydraulics tsa literaka, ba sebetsang ka morao ho ts'ebetso ho boloka ntho e 'ngoe le e' ngoe e sebetsa joalo ka mochini o tlotsitsoeng hantle. Meetso e mengata e tloaelehileng ea li-valve e sebetsana le lits'ebetso tse fapaneng tsa hydraulic tsa literaka:
- Li-valve tsa Directional Control: Li-valve tsena li laola tsela ea phallo ea mokelikeli oa hydraulic ka likou tse ngata le maemo. Litlhophiso li tloha ho ts'ebetso e bonolo ea ho tima / ho tima ho isa taolong e lekanyelitsoeng bakeng sa motsamao o ntseng o eketseha.
- Li-valve tsa Taolo ea Khatello: Li-valve tsena li laola khatello ea tsamaiso, ho fana ka tšireletso e feteletseng, ho fokotsa khatello, kapa ho latellana ha khatello. Li-valve tsa liphallelo li sebetsa e le lisebelisoa tsa tšireletso, li fokotsa khatello e phahameng ho thibela tšenyo ea likaroloana. Li-valve tse fokotsang li boloka khatello e sa khaotseng ea noka ho sa tsotellehe khatello e ntseng e phahama. Li-valve tsa tatellano li etelletsa phallo pele ho mesebetsi ea bohlokoa pele li lumella mokelikeli ho lipotoloho tsa bobeli.
- Li-valve tsa Taolo ea Phallo: Ho fetola sekhahla sa phallo ea metsi a hydraulic ho ama lebelo la li-actuator. Li-valve tsa taolo ea phallo li tsamaisa phallo ea mokelikeli ho fetola lebelo la actuator bakeng sa ts'ebetso e nepahetseng ea lisebelisoa. Li tla ka mefuta e nang le khatello ea khatello ho boloka phallo e tsitsitseng ho sa tsotellehe meroalo e sa tšoaneng le mefuta e sa lefelloeng e fetolang phallo e amanang le ho fetoha ha khatello.
Mekhoa ea Ts'ebetso ea Valve
Li-valve tsa taolo li kanna tsa sebetsa ka morao ho liketsahalo empa li boetse li itšetlehile ka opareitara, ka mefuta e fapaneng ea taolo ho latela mofuta oa koloi.
- Manual: Li-levers kapa pedals li fana ka taolo e tobileng ea opareitara holim'a mesebetsi ea li-valve. Li-valve tsa matsoho li bonolo ebile lia tšepahala empa li hloka ho kenya letsoho kamehla.
- Mechini: Lik'hamera, li-plungers kapa lisebelisoa tse ling tsa mochini li kenya li-valve ka bo eona ho latela boemo ba sesebelisoa kapa motsamao. Li-valve tsa mechine li fana ka ts'ebetso e ikemetseng ntle le matla a ka ntle.
- Pneumatic: Li-valve tsa moea tse hatelitsoeng, tse lumellang mofofisi oa sefofane ho tloha ho li-switches tse tsamaisoang ke moea kapa li-joystick.
- Hydraulic: Fluid pressure pilot valves spools, e nolofalletsang taolo e hole joalo ka mefuta ea moea. Hydraulic actuation e sebetsana le matla a holimo bakeng sa lits'ebetso tse boima.
- Solenoid: Ha e na le matla, li-coil tsa electromagnetic li fetola li-valve tsa li-valve, tse fanang ka taolo ea motlakase ho tloha ho li-switches, li-relay, kapa li-module tsa taolo ea elektroniki. Li-valve tsa Solenoid li fana ka karabelo e potlakileng le automation e laoloang ke komporo.
Boholo le Khetho
Li-valve tsa taolo tse boletsoeng hantle li netefatsa ts'ebetso e nepahetseng le ho ts'epahala. Nahana ka lintlha tsena ha u etsa boholo le ho khetha li-valve:
- Boholo ba Boema-kepe le Bokhoni ba Phallo: Bophahamo ba phallo ea li-valve bo lokela ho ts'oana le sekhahla sa phallo ea hydraulic system bakeng sa tlhahiso e phahameng ea pompo le litlhoko tsa actuator.
- Tekanyetso ea Khatello: Li-valve li lokela ho ba le litekanyetso tsa khatello tse fetang ka mokhoa o sireletsehileng khatello ea sistimi, ho kenyeletsoa le li-spikes tse ka bang teng.
- Tlhophiso le Mosebetsi: Litlhophiso tsa li-valve li tlameha ho fana ka taolo e lakatsehang ea tataiso, taolo ea khatello, kapa ts'ebetso ea phetoho ea phallo.
- Tikoloho le Tšebelisano ea Mokelikeli: Lisebelisoa tsa li-valve li lokela ho lumellana le mofuta oa mokelikeli oa haeteroliki o sebelisoang le maemo afe kapa afe a tikoloho, joalo ka mocheso o feteletseng kapa ho pepesehela litšila.
Ikopanye le rona neng kapa neng haeba o hloka thuso ho khetha li-valve tse nepahetseng tsa taolo.
