Li-Actuator tsa Motlakase

Li-motors tsa motlakase li lumella ho sebetsa ha valve ka tataiso, semi-automatic le othomathike. Li-motor li sebelisoa haholo bakeng sa mesebetsi e haufi-ufi, leha li khona ho beha valve sebakeng leha e le sefe se bulehileng joalo ka ha ho bontšitsoe setšoantšong se ka tlase. Hangata enjene ke mofuta, o ka fetolehang morao, oa lebelo le holimo o hokahaneng ka terene ea gia ho fokotsa lebelo la enjene mme ka hona e eketsa torque kutung. Tataiso ea ho potoloha ha enjene e etsa qeto ea hore na motsamao oa disk o hokae.
Ts'ebetso ea motlakase e ka ba semi-automatic, joalo ka ha enjene e qalisoa ke sistimi ea taolo. Lebili la letsoho, le ka kenang tereneng ea gear, le fana ka ts'ebetso ea letsoho ea valve. Li-switch tsa moeli hangata li fanoa ho emisa enjene ka bo eona sebakeng se bulehileng le se koetsoeng ka botlalo. Li-switch tsa moeli li sebetsoa ka 'mele ka boemo ba valve kapa ka torsionally ka torque ea enjene.

Li-Actuator tsa Hydraulic

Li-actuator tsa Hydraulic li fana ka sebaka sa semi-automatic kapa sa othomathike sa valve, se ts'oanang le li-pneumatic actuators. Li-actuator tsena li sebelisa piston ho fetola khatello ea lets'oao hore e be motsamao oa kutu ea valve. Mokelikeli oa Hydraulic o fepeloa ka lehlakoreng le leng la piston ha lehlakore le leng le tsoa kapa le tsoa mali. Metsi kapa oli e sebelisoa e le mokelikeli oa hydraulic. Li-valve tsa Solenoid hangata li sebelisetsoa ho laola metsi a hydraulic ho tsamaisa ho bula kapa ho koala ha valve. Li-valve tsa letsoho li ka boela tsa sebelisoa bakeng sa ho laola metsi a hydraulic; ka hona ho fana ka ts'ebetso ea semi-automatic.

Li-valve tse Ikemetseng

Li-valve tse ikemetseng li sebelisa mokelikeli oa tsamaiso ho beha valve. Li-valve tsa liphallelo, li-valve tsa tšireletso, li-valve tsa ho hlahloba, le li-trap tsa mouoane ke mehlala ea li-valve tse itšebetsang. Li-valve tsena kaofela li sebelisa tšobotsi e itseng ea mokelikeli oa tsamaiso ho kenya valve. Ha ho na mohloli oa matla ka ntle ho matla a mokelikeli o hlokahalang bakeng sa ts'ebetso ea li-valve tsena.

Li-valve tsa solenoid tse le 'ngoeli bitsoa hloleha ho bula kapa ho hlōleha ho koaloa ho itšetlehile ka boemo ba valve e nang le solenoid de-energized. Li-valve tsa solenoid tse hlolehang li buloa ke khatello ea selemo ebe li koaloa ka ho matlafatsa solenoid. Li-valve tsa solenoid tse sa sebetseng li koetsoe ke khatello ea selemo 'me li buloa ka ho matlafatsa solenoid. Li-valve tse peli tsa solenoid hangata li hloleha "joalo ka ha li le". Ke hore, boemo ba valve ha bo fetohe ha li-solenoids ka bobeli li fokotsehile.
Tšebeliso e 'ngoe ea li-valve tsa solenoid ke lits'ebetsong tsa moea tse kang tse sebelisetsoang ho fana ka moea ho li-actuator tsa pneumatic valve. Li-valve tsa solenoid li sebelisoa ho laola phepelo ea moea ho mochini oa moea, kahoo boemo ba valve ea pneumatic actuated.

Lebelo la Lisebelisoa tsa Matla

Lintlha tsa polokeho ea limela li laela lebelo la li-valve bakeng sa li-valve tse itseng tse amanang le polokeho. Moo sistimi e tlamehang ho aroloa kapa ho buloa kapele haholo, ho hlokahala hore ho sebelisoe li-valve ka potlako haholo. Moo ho buloa ha valve ho fellang ka ente ea metsi a batlang a bata haholo tsamaisong e chesang, ho bula butle hoa hlokahala ho fokotsa mocheso oa mocheso. Moralo oa boenjiniere o khetha actuator bakeng sa li-valve tse amanang le polokeho tse ipapisitseng le lebelo le litlhoko tsa matla le boteng ba matla ho actuator.

Ka kakaretso, actuation e potlakileng haholo e fanoa ke li-hydraulic, pneumatic, le solenoid actuators. Leha ho le joalo, li-solenoids ha li sebetse bakeng sa li-valve tse kholo hobane boholo ba tsona le litlhoko tsa matla li ka ba tse feteletseng. Hape, li-hydraulic le pneumatic actuators li hloka mokhoa oa ho fana ka matla a hydraulic kapa pneumatic. Lebelo la actuation maemong afe kapa afe le ka beoa ka ho kenya li-orifices tse boholo bo loketseng methalong ea hydraulic kapa pneumatic. Maemong a mang, valve e koetsoe ke khatello ea selemo, e hanyetsanang le khatello ea hydraulic kapa pneumatic ho boloka valve e bulehile.

Li-motor tsa motlakase li fana ka ts'ebetso e batlang e potlakile. Lebelo la sebele la li-valve le behiloe ke motsoako oa lebelo la koloi le tekanyo ea gear. Motsoako ona o ka khethoa ho fana ka leeto le felletseng la li-valve ka har'a moeli ho tloha metsotsoana e ka bang peli ho isa metsotsoana e mengata.

Letšoao la Boemo ba Valofo

Basebelisi ba hloka pontšo ea boemo ba li-valve tse itseng ho lumella ts'ebetso e nang le tsebo ea semela. Bakeng sa li-valve tse joalo, pontšo ea boemo ba li-valve tse hōle e fanoa ka mokhoa oa mabone a boemo a bontšang hore na li-valve li bulehile kapa li koetsoe. Lipotoloho tse bonts'ang boemo ba li-valve tse hole li sebelisa sesebelisoa sa boemo bo utloang kutu le boemo ba disk kapa boemo ba actuator. Mofuta o mong oa detector ea boemo ke mochine oa moeli oa mochine, o sebelisoang ke ho sisinyeha ha valve.

Mofuta o mong ke li-switch tsa makenete kapa li-transformer tse utloang ho sisinyeha ha li-cores tsa tsona tsa makenete, tse tsamaisoang ke ho sisinyeha ha valve.

Letšoao la boemo ba valve le bolela tšobotsi e bonahalang ea valve e bontšang boemo ba valve. Boemo ba valve ea stem e ntseng e phahama bo bontšoa ke boemo ba stem. Li-valve tsa stem tse sa tsoheng ka linako tse ling li na le litsupa tse nyane tsa mochini tse sebelisoang ke mochini o sebetsang ka nako e le 'ngoe le ts'ebetso ea valve. Li-valve tse nang le matla a motlakase hangata li na le sesupo sa mochini se fanang ka sesupo sa boemo ba li-valve tsa lehae. Ka lehlakoreng le leng, li-valve tse ling ha li na tšobotsi leha e le efe bakeng sa pontšo ea boemo.
