Karolo e 'ngoe ea bohlokoa e bapalang karolo ea bohlokoa ho ntlafatseng lits'ebetso tsena ke valve e sebetsang ea sefofane. Joaloka morekisi ea ka sehloohong oa li-valve tsa ho hlahloba tse tsamaisoang ke lifofane, re utloisisa bohlokoa ba tsona ho ntlafatsa ts'ebetso ea ts'ebetso. Tataiso ena e tla shebisisa melemo, lits'ebetso, le lintlha tsa bohlokoa tsa ho kopanya li-valve tse sebetsang ka har'a sistimi ea hau ea taolo.
Li-valve tsa ho hlahloba li-Pilot ke life?
Li-valve tsa ho hlahloba li-pilot ke lisebelisoa tse khethehileng tse etselitsoeng ho lumella ho phalla ka tsela e le 'ngoe ha li ntse li thibela ho khutlela morao. Ho fapana le li-valve tse tloaelehileng tsa ho hlahloba, liphetolelo tse sebetsang ka sefofane li sebelisa letšoao la sefofane ho laola mokhoa oa ho bula le oa ho koala, o fana ka ho nepahala le ho arabela haholoanyane. Ts'ebetso ena e etsa hore e be tse loketseng bakeng sa lits'ebetso tse fapaneng tsa indasteri moo taolo ea phallo le botsitso ba sistimi li leng bohlokoa.
Melemo ea Pilot Operated Check Valves
1. Taolo ea Phallo e Matlafalitsoeng: Li-valve tsa ho hlahloba tse tsamaisoang ke lifofane li fana ka taolo e phahameng holim'a phallo ea mokelikeli, e leng ho lumellang hore tsamaiso e sebetse hantle haholoanyane. Bokhoni ba bona ba ho laola litekanyetso tsa phallo ka katleho bo ka lebisa ho ntlafatseng ts'ebetso ea ts'ebetso le ho fokotsa tšebeliso ea matla.
2. Fokotsa Leakage: Li-valve tsena li etselitsoe ho fokotsa ho lutla, ho bohlokoa bakeng sa ho boloka khatello ea tsamaiso le ho thibela tahlehelo ea mokelikeli. Karolo ena ha e ntlafatse ts'epahalo ea sistimi feela empa e boetse e kenya letsoho ho bolokeng litšenyehelo ka kakaretso.
3. Tšireletseho e Ntlafetseng: Ka ho thibela ho khutlela morao, li-valve tsa ho hlahloba tse tsamaisoang ke lifofane li thusa ho sireletsa lisebelisoa le basebetsi likotsing tse ka 'nang tsa amahanngoa le ho fetoha ha metsi. Karolo ena ea polokeho e bohlokoa haholo lits'ebetsong tsa khatello e phahameng.
4. Likopo tse fapaneng: Li-valve tsa ho hlahloba tse tsamaisoang ke lifofane li loketse mefuta e mengata ea liindasteri, ho akarelletsa le oli le khase, phekolo ea metsi, ts'ebetso ea lik'hemik'hale le tlhahiso. Ho feto-fetoha ha tsona ho etsa hore e be khetho e ntle bakeng sa litsamaiso tse fapaneng tsa taolo.
Lisebelisoa tsa Pilot Operated Check Valves
1. Hydraulic Systems: Lits'ebetsong tsa hydraulic, li-valve tsa ho hlahloba tse tsamaisoang ke lifofane li thusa ho boloka khatello ea tsamaiso le ho thibela ho khutlela morao, ho etsa bonnete ba hore ho sebetsa hantle le ho ntlafatsa tšireletso.
2. Pneumatic Systems: Li-valve tsena li boetse li sebelisoa haholo mekhoeng ea moea ho laola phallo ea moea le ho boloka maemo a khatello, e leng se tlatsetsang ho sebetsa hantle.
3. Tsamaiso ea Metsi le Litšila: Litsing tsa phekolo ea metsi, li-valve tsa ho hlahloba tse tsamaisoang ke lifofane li phetha karolo ea bohlokoa ho thibela ho khutlela morao le ho netefatsa botšepehi ba phepelo ea metsi.
4. Taolo ea Ts'ebetso: Ts'ebetsong ea lik'hemik'hale, li-valve tsena li thusa ho laola phallo ea metsi a sa tšoaneng, ho netefatsa taolo e nepahetseng le ho fokotsa kotsi ea tšoaetso.
Lintlha tsa Bohlokoa Ha U Khetha Pilot e sebelitsoeng Hlahloba Li-valve
1. Ho lumellana ha Lintho: Etsa bonnete ba hore lisebelisoa tsa valve li lumellana le maro a tsamaisoang. Sena se bohlokoa bakeng sa ho thibela kutu le ho lelefatsa nako ea bophelo ea valve.
2. Litekanyetso tsa Khatello le Mocheso: Khetha li-valve tse ka mamellang khatello e khethehileng le maemo a mocheso a kopo ea hau. Sena se tiisa ts'ebetso e tšepahalang le polokeho.
3. Phallo Rate: Nahana ka sekhahla sa phallo e hlokahalang bakeng sa sistimi ea hau. Ho khetha boholo bo nepahetseng ba li-valve le mofuta oa tsona ho bohlokoa bakeng sa ts'ebetso e nepahetseng.
4. Litlhoko tsa Tlhokomelo: Hlahloba litlhoko tsa tlhokomelo ea li-valve. Khetha meralo e thusang ho lokisoa habonolo ho fokotsa nako.

Li-valve tsa ho hlahloba tse tsamaisoang ke lifofane ke likarolo tsa bohlokoa bakeng sa litsamaiso tse sebetsang tsa taolo liindastering tse fapaneng. Bokhoni ba bona ba ho ntlafatsa taolo ea phallo, ho fokotsa ho lutla, le ho ntlafatsa polokeho ho ba etsa letsete la bohlokoa bakeng sa khoebo efe kapa efe. Joaloka mofani oa thepa ea tšepahalang, re fana ka mefuta e mengata ea li-valve tsa boleng bo holimo tse sebetsang ka sefofane tse etselitsoeng ho fihlela litlhoko tsa hau tse khethehileng.
