A koala valveke karolo ea bohlokoa litsamaisong tsa liphaephe tse etselitsoeng ho laola phallo ea metsi kapa likhase. Ka ho bula, ho koala, kapa ho thibela litsela ka karolo e itseng, li-valve tsena li netefatsa polokeho, li laola khatello, le ho thibela ho lutla. Ebang ke liphaepheng tsa matlo, lits'ebetsong tsa indasteri, kapa liphaepheng tsa oli le khase, li-valve tse koetsoeng lia hlokahala bakeng sa ts'ebetso e ntle ea sistimi le taolo ea maemo a tšohanyetso.
Mefuta ea Li-valve tsa ho Koala
Li-valve tse timang li tla ka meralo e fapaneng, e 'ngoe le e 'ngoe e loketse lits'ebetso tse itseng. Mefuta e tloaelehileng haholo ke ena:
Valve ea Bolo
Valve ea bolo e sebelisa bolo e potolohang e nang le mokoti ho laola phallo. E fana ka ho tima kapele, ho tšoarella, le ho theoha ho fokolang ha khatello. E loketse litsamaiso tsa metsi, khase le oli.
Valve ea Heke
Li-valve tsa heke li na le heke e bōpehileng joaloka wedge e phahamisang ho lumella phallo. Li molemo ka ho fetisisa bakeng sa taolo ea ho bula/ho tima lits'ebetsong tse nang le maqhubu a tlase, joalo ka mela ea phepelo ea metsi.
Valve ea Lefatše
Li-valve tsa globe tse tsebahalang ka taolo e nepahetseng ea phallo, li sebelisa mokhoa oa disc le setulo. Li tloaelehile litsamaisong tsa HVAC le liphaepheng tsa mafura.
Valve ea Serurubele
Valo e nyane, e bobebe e nang le diski e potolohang. Valo ea serurubele e ipabola haholo lits'ebetsong tse kholo tsa kalafo ea metsi le tšireletso ea mollo.
Hlahloba Valve
E dumella phallo ho ya ka lehlakoreng le le leng feela, e thibela phallo e kgutlelang morao. E sebediswa ditsamaisong tsa dikgwerekgwere le methapong ya ho ntsha metsi ka pompong.
Valve ea Diaphragm
E sebelisa diaphragm e tenyetsehang ho arola phallo. E loketse maro a senyang kapa a lerōle ha ho sebetsoa lik'hemik'hale.
Valve ea nale
E etselitsoe taolo e nepahetseng ea phallo ka sesebelisoa sa ho phunya se kang nale se tenya. E tloaelehile litsamaisong tsa lisebelisoa le tsa haeteroliki.
ESDV (Valve ea ho Thibela Maemo a Tšohanyetso)
Valve e khethehileng bakeng sa ho koala ka potlako nakong ea maemo a tšohanyetso, hangata e iketsahalla. E bohlokoa haholo libakeng tsa ho hloekisa oli le liphaephe tsa khase.
Tšebeliso ea Li-valve tsa ho Thibela
Li-valve tse koetsoeng li phetha karolo e fapaneng ho pholletsa le liindasteri:
- Motseng: Arola phepelo ea metsi nakong ea litokiso (mohlala, li-valve tsa bolo tlas'a lisinki).
- Indasteri: Laola mouoane, lik'hemik'hale, kapa mafura (li-valve tsa globe, li-valve tsa diaphragm).
- Oli le KhaseNetefatsa polokeho ka di-ESDV nakong ya ho dutla kapa kgatello e phahama.
- Tšireletso ea Mollo: Li-valve tsa serurubele li nolofalletsa taolo e potlakileng ea phallo ea metsi lits'ebetsong tsa ho fafatsa.
- Meriana: Li-valve tsa nale li boloka ho nepahala ha ho sebelisoa ha mokelikeli.
Li-valve tsa ho tima li sebetsa joang
Mokhoa oa ts'ebetso o fapana ho ea ka mofuta empa o latela molao-motheo o akaretsang:
1. Ts'ebetso: Li-valve li sebelisoa ka letsoho (lebili la letsoho, lever) kapa ka boiketsetso (li-actuator tsa motlakase/pneumatic).
2. Taolo ea Phallo:
–Li-valve tsa bolo/serurubele: Potoloha ka 90° ho bula/ho kwala.
–Li-valve tsa Heke/Globe: Motsamao o otlolohileng o phahamisa/theola heke kapa disk.
–Li-valve tsa ho hlahloba: Itšetlehe ka khatello ea phallo ho bula/ho koala.
3. Ho tiisa: Litiiso tse tiileng (rabara, PTFE) li thibela ho dutla ha li koetsoe.
Ho Khetha Valve e Nepahetseng
Ho khetha valve ea ho tima ho latela lintlha tse latelang:
- Mofuta oa Mokelikeli: Metsi a senyang a hloka di-valve tsa diaphragm; dikhase di tshwanela di-valve tsa bolo.
- Khatello/Mocheso: Litsamaiso tse nang le khatello e phahameng li hloka li-ESDV tse matla kapa li-valve tsa heke.
- Khafetsa ea Tšebeliso: Li-valve tsa bolo li nka nako e telele lits'ebetsong tsa potoloho e phahameng.
Qetello
Ho tloha ho li-ESDV tse libakeng tse kotsi ho ea ho li-valve tse bonolo tsa bolo malapeng, li-valve tse koetsoeng ke mokokotlo oa litsamaiso tsa taolo ea mokelikeli. Ho utloisisa mefuta ea tsona, ts'ebeliso le mechini ho netefatsa ts'ebetso e ntle le polokeho. Tlhokomelo e tloaelehileng le khetho e nepahetseng ea li-valve li ntlafatsa bophelo bo bolelele ba sistimi.
