Leha ho le joalo, phephetso e tloaelehileng eo basebetsi ba tobanang le eona keho phahamisa li-valve tsa heke—ketsahalo e behang tshebetso e ntle kotsing, polokeho le bophelo bo bolelele. Jwalo ka motho ya tshepahalangFektheri ea valve ea heke ea China, re utloisisa bohlokoa ba ho rarolla bothata bona. Sehloohong sena, re tla hlahloba hore na ho hola ke eng, likotsi tsa hona, lisosa tsa motheo, le hore na mahlale a tsoetseng pele a ho koahela a ka e thibela joang. Re tla boela re arolelane likhothaletso tsa litsebi tse tsoang hobahlahisi ba li-valve tsa hekele ho hlakisa liphapang lipakeng tsavalve ea lefats'e khahlanong le valve ea hekelits'ebetso.
1. Ho Sekala Li-valve tsa Heke ke Eng?
Ho lekanya ho bolela ho bokellana ha diminerale tse setseng, tse kang calcium carbonate, silica, kapa sulfates, hodima di-valve tsa heke. Di-deposit tsena di bopeha ha diminerale tse qhibilihisitsweng ka hara metsi di kopana mme di kgomarela dikarolo tsa tshepe, haholoholo tlasa dithempereichara tse phahameng kapa diphetoho tsa kgatello. Ha nako e ntse e ya, ho lekanya ho etsa lera le thata, le nang le makukuno le sitisang tshebetso ya di-valve.
Bakeng sali-valve tsa heke, ho lekanya hangata ho shebana le libaka tsa bohlokoa tse kang wedge, setulo le kutu.li-valve tsa lefats'e(tse sebelisang mokhoa oa ho kenya le ho kenya setulo), li-valve tsa heke li itšetlehile ka heke e bataletseng kapa e bōpehileng joaloka wedge ho laola phallo. Ho eketsa likarolo tsena ho ka lebisa ho koaloeng ho sa fellang kapa khohlano e eketsehileng nakong ea ts'ebetso.
2. Likotsi tsa ho Sekaseka Li-valve tsa Heke
Ho eketsa boholo ba thepa ha se bothata bo boholo feela—ho baka likotsi tse tebileng tsa ts'ebetso le tsa lichelete:
- Bokgoni bo Fokotseng: Li-depositi li thibela phallo ea mokelikeli, li qobella litsamaiso ho sebetsa ka thata le ho eketsa tšebeliso ea matla.
- Ho dutla ha metsi: Ho lekanya ho thibela heke ho kwala ka botlalo, e leng se lebisang ho dutleng le dikotsing tse ka bang teng tikolohong.
- Ho Potlakisa ho Ts'enyeho: Li-depositi li tšoara mongobo, li potlakisa ho bola ka tlas'a lera la sekala.
- Litšenyehelo tse Eketsehileng tsa Tlhokomelo: Ho hlwekisa khafetsa kapa ho nkela dikarolo tse ding sebaka ho eketsa nako ya ho se sebetse le ditshenyehelo.
- Likotsi tsa Polokeho: Maemong a feteletseng, ho hloleha ha valve ka lebaka la ho hola ho ka baka kgatello e feteletseng ya sistimi kapa ho tima.
Bakeng sa liindasteri tse kang oli le khase, ts'ebetso ea lik'hemik'hale, kapa kalafo ea metsi, likotsi tsena ha li amohelehe. Ke ka lebaka lena ho etella pelelifektheri tsa li-valve tsa hekeho beha pele thibelo ea ho hola.
3. Hobaneng ha ho ba le ho lekanya ho etsahala ho di-valve tsa heke
Ho utloisisa lisosa tsa ho hola ke senotlolo sa thibelo:
- Boleng ba Metsi: Metsi a thata a nang le diminerale tse ngata ke sesosa se seholo.
- Ho feto-fetoha ha mocheso: Metsi a futhumatsang kapa a phodisang a ka baka pula ya diminerale.
- Mabelo a Phallo e Tlase: Maemo a sa sisinyeheng a dumella diminerale ho dula hodima di-valve.
- Ho lumellana ha thepa: Li-valve tsa tšepe ea carbon e sa koaheloang li na le tšekamelo ea ho hola ho feta tšepe e sa hloekang kapa mekhoa e meng e koahetsoeng.
- Tlhokomelo e Fosahetseng: Litlhahlobo tse sa etsoeng khafetsa li lumella li-depositi ho bokellana li sa hlokomeloe.
Ha ho bapisoa leli-valve tsa lefats'e, tse sebetsanang le ho thiba le ho lokisa khafetsa, li-valve tsa heke hangata li sebelisoa lits'ebetsong tsa ho bula/ho tima. Leha ho le joalo, mefuta ena ka bobeli ea li-valve e kotsing ea ho hola ntle le tšireletso e nepahetseng.
4. Mokhoa oa ho Thibela ho Sekala ho Li-valve tsa Heke
Mehato e potlakileng e ka fokotsa likotsi tsa ho hola:
- Kalafo ea Metsi: Sebelisa di-softeners kapa di-inhibitor tsa dikhemikhale ho fokotsa bongata ba diminerale ka hara maro.
- Tlhokomelo ea Kamehla: Rera tlhahlobo le tlhoekiso ho tlosa depositi tsa mohato wa pele.
- Ntlafatso ea Lintho tse bonahalang: Khetha metsoako e kopantsoeng e sa senyeheng joaloka tšepe e sa hloekang kapa tšepe e habeli.
- Liphetoho tsa Ts'ebetso: Boloka lebelo le nepahetseng la phallo ho fokotsa ho se tsitse.
- Liaparo tse Tsoetseng Pele: Kenya masela a khethehileng a thibelang ho hola holim'a li-valve.
Har'a litharollo tsena, theknoloji ea ho koahela e ikhetha ka ho sebelisa chelete hantle le ts'ebetso ea eona ea nako e telele.
5. Kamoo Liaparo li Thibelang ho Sekala ho Li-valve tsa Heke
Liaparo li etsa mokoallo o sireletsang pakeng tsa libaka tsa li-valve le maro a nang le liminerale tse ngata. Mokhoa oa ho sebetsa ke ona:
- Sebaka se sa Khomareleng: Liaparo tse kang PTFE (Teflon) kapa epoxy li fokotsa ho teteana ha bokaholimo, e leng se etsang hore ho be thata hore liminerale li khomarele.
- Khanyetso ea Lik'hemik'hale: Liaparo tse ling li fokotsa li-ion tse arabelang ka har'a metsi, li thibela ho kristaletsoa.
- Ho Tsitsisa ha Thermal: Liaparo tse nang le mocheso o phahameng li mamella potoloho ea mocheso ntle le ho senyeha.
- Tšireletso ea ho Silafala: Ka ho sireletsa tšepe mongobong, masela a loantša ho hola le mafome.

Mohlala,fektheri ea li-valve tsa hekee ka sebelisa sekoahelo sa HVOF (High-Velocity Oxygen Fuel) ho fihlela qetello e boreleli haholo holim'a libaka tsa wedge.
6. Litlhahiso tsa Litsebi tse tsoang ho Baetsi ba Li-valve tsa Heke
Ho eketsa khanyetso ea ho hola, latela malebela ana ho tsoa ho litsebi tsa indasteri:
1. Khetha Seaparo se Nepahetseng: Bapisa thepa ea ho roala le mofuta oa mokelikeli oa hau. Mohlala:
– PTFE bakeng sa ho hanyetsa lik'hemik'hale.
– Liaparo tsa letsopa bakeng sa lits'ebetso tsa mocheso o phahameng.
– Liaparo tse entsoeng ka nikeli bakeng sa maro a khorofo.
2. Sebelisana le Bafani ba Tšepahalang: Sebetsa le setifikeitibahlahisi ba li-valve tsa hekeho netefatsa boleng ba ho koahela le ho latela melao.
3. Kopanya Litharollo: Kopanya dikobo le kalafo ya metsi bakeng sa tshireletso e ntlafetseng.
4. Lekola Tshebetso: Sebelisa li-sensor ho latela ho theoha ha khatello kapa liphetoho tsa phallo tse eketsang lets'oao.
5. Ruta Lihlopha: Koetlisa basebetsi ho lemoha matšoao a pele a ho hola ha thepa nakong ea tlhokomelo.
Ho phaella moo, nahana ka mofuta oa valve:li-valve tsa lefats'e khahlanong le li-valve tsa hekeLeha dikoahelo di thusa ka bobedi, di-valve tsa heke (tse sebediswang haholoholo bakeng sa ho itšehla thajana) di ka hloka dikoahelo tse teteaneng hekeng, athe di-valve tsa globe (tse sebediswang bakeng sa taolo ya phallo) di hloka dikoahelo polakeng le setulong.
