Maqhubu a phallang: Kopo le Melemo

Li-valve tsa ho pota-pota ke lisebelisoa tse bolokang khatello ea tsamaiso ka mokhoa o sa khaotseng. Ho seng joalo ba bitsoa li-valve tse khaphatsehang. Ho fapana le ts'ireletso, metsi kapa khase ho tsona li khelosoa kamehla. Sebakeng sa polokelo ea polokeho, khatello ea tsamaiso e bolokiloe ke ho tlosoa ha nako ka nako ea khase kapa metsi. Ka mokhoa o hlophisitsoeng, lisebelisoa tsena le tse ling ha li fapane.

Kopo

Li-valve tse phallang li sebelisoa litsing tse hlokang tlhokomelo ea kamehla moemong o itseng oa tikoloho ea ka hare. Ka mohlala, ka koloing ba kenngoa ka ho toba haufi le pompo ea peterole kapa ba kenyelelitsoe moqapong oa eona. Ho sebetsa ha valve ho khutlisetsa peterole e feteletseng leboteng la peterole, le bolokang khatello ea kamehla ts'ebetsong. Enjene ea motlakase e ka hare e na le tsamaiso ea ho pholisa, moo li-valve tse ka holimo li kenngoa teng, ka lebaka la hore se pholileng se khutlisetsoa radiator ea pholileng e tsoang tanka ea ho atolosa. Lisebelisoa li boetse li sebelisoa lipotolohong tsa kamore ea boiler, moo li bolokang ho phalla ha mohloli oa mocheso ka potoloho.

Melemo

Li-valve tse phallang li na le melemo e 'maloa:

• Bonolo ba sesebelisoa, ho fana ka botšepehi bo phahameng ba moqapi;
• U se ke ua batla hore ho sebelisoe lisebelisoa tse eketsehileng tsa matla;
• Ha ho hlokahale tlhokomelo;
• E phahamisitsoe kae kapa kae tsamaisong;
• Theko e tlaase.

Li-valve bakeng sa metsi

Lik'hamphani tse fapaneng li fana ka lisebelisoa tse laolang khatello ea metsi ho eona, esita le ka mor'a eona, liphahlo tse laolang phallo, ho tsoa, polokeho le moea. Ha ho futhumatsa lisebelisoa, li kenngoa moeeng o otlolohileng. Nakong ea ha khatello ea metsi e nyolohela ho valve, e bula, 'me phallo ea metsi e romeloa ka pipe ea lekala ho ea ka pipeline ea khutlisetso. Haeba boemo ba khatello e ka tlaase ho phaepe ea pele, e koala. Boqapi ba eona bo u lumella hore u fetole maemo a khatello ka letsoho le khethehileng la letsoho. Bellows seal stem ha e hloke tlhokomelo. Valve ea ho potoloha bakeng sa metsi e kenngoa mananeong a ho tsamaisa metsi. Lisebelisoa tsena li khetholloa ke ts'ebetso e phahameng, bophelo bo bolelele le ho tšepahala.

Mahlaseli a compressor

The compressor by-pass valve ke ntho e boima ea moqapi, ka lebaka la hore thepa e sebetsa ka tsela e tloaelehileng le e sa lefelloe haholo. Moruo oa litekanyetso o itšetlehile ka matla a eona, kahoo e lokela ho koaloa ka nako le e thata, e be le ho hanyetsa haholo, e mamelle maemo a phahameng a holimo le mejaho e matla. Ho na le mefuta e meng ea li-valve bakeng sa compressor:

• Li-valve tsa polokeho, tse hlokahalang ho tiisa hore ho tsoa khatello e feteletseng ha e le ka holim'a boemo bo amohelehang. Tabeng ena, sesebelisoa se bula, ho lokolla moea, 'me ha khatello e theoha, e qetella e koala.
• Sheba li-valve tse thibelang khatello e le hore compressor leha e le efe e emise ho thibela moea o hatelitsoeng ho tloha ho khutlela ho compressor.
• Li-valve li laolang li-load (li-bypass) li fokotsa mojaro kahare ea motlakase nakong ea ho qala. Ka bona, cylinder e phahameng e hatella le tikoloho e ka ntle mme e ntša khatello e feteletseng.
