Valve e le sesebelisoa e hlahile ka lilemo tse likete

Valveke sesebelisoa se sebelisoang phetisong le taolong ea khase le mokelikeli se nang le bonyane lilemo tse sekete tsa nalane.

Hona jwale, tsamaisong ya diphaephe tsa metsi, valve e laolang ke karolo ya taolo, mme mosebetsi wa yona o ka sehloohong ke ho arola disebediswa le sistimi ya diphaephe, ho laola phallo, ho thibela phallo e kgutlelang morao, ho laola le ho ntsha kgatello. Kaha ho bohlokwa haholo ho kgetha valve e laolang e loketseng ka ho fetisisa bakeng sa sistimi ya diphaephe, ho bohlokwa hape ho utlwisisa dibopeho tsa valve le mehato le motheo wa ho kgetha valve.

Khatello e tloaelehileng ea valavu

Kgatelelo e tloaelehileng ea valve e bolela khatello e fanoeng moralo e amanang le matla a mechini a likarolo tsa liphaephe, ke hore, ke khatello e lumelletsoeng ea valve mochesong o boletsoeng, e amanang le thepa ea valve. Khatello ea ho sebetsa ha e tšoane, ka hona, khatello e tloaelehileng ke paramethara e itšetlehileng ka thepa ea valve 'me e amana le mocheso o lumelletsoeng oa ho sebetsa le khatello ea ho sebetsa ea thepa.

Valve ke setsi tsamaisong ea potoloho e mahareng kapa tsamaisong ea khatello, e sebelisetsoang ho lokisa phallo kapa khatello ea setsi. Mesebetsi e meng e kenyelletsa ho tima kapa ho bulela mecha ea phatlalatso, ho laola phallo, ho fetola tsela eo mecha ea phatlalatso e tsamaeang ka eona, ho thibela phallo ea mecha ea phatlalatso e khutlelang morao, le ho laola kapa ho ntša khatello.

Mesebetsi ena e finyelloa ka ho fetola boemo ba ho kwala ha valve. Tokiso ena e ka etsoa ka letsoho kapa ka boiketsetso. Ts'ebetso ea letsoho e boetse e kenyelletsa ts'ebetso ea ho laola drive ka letsoho. Li-valve tse sebelisoang ka letsoho li bitsoa li-valve tsa letsoho. Valve e thibelang phallo ea metsi e bitsoa valve ea ho hlahloba; e laolang khatello ea thuso e bitsoa valve ea polokeho kapa valve ea thuso ea polokeho.

Ho fihlela joale, indasteri ea li-valve e khonne ho hlahisa mefuta e felletseng eali-valve tsa heke, di-valve tsa lefatshe, di-valve tsa throttle, di-valve tsa polaka, di-valve tsa bolo, di-valve tsa motlakase, di-valve tsa taolo ya diaphragm, di-valve tsa ho hlahloba, di-valve tsa polokeho, di-valve tse fokotsang kgatello, maraba a mouoane le di-valve tsa ho tima tshohanyetso. Dihlahiswa tsa di-valve tsa mekhahlelo e 12, mehlala e fetang 3000, le ditlhaloso tse fetang 4000; kgatello e phahameng ya ho sebetsa ke 600MPa, bophara bo boholo ba lebitso ke 5350mm, mocheso o phahameng wa ho sebetsa ke 1200℃, mocheso o tlase oa ho sebetsa ke -196℃, 'me sesebelisoa se sebetsang ke Metsi, mouoane, oli, khase ea tlhaho, mecha e matla e senyang (joalo ka asiti ea nitric e matla, asiti ea sulfuric e mahareng, jj.).

Ela hloko khetho ea li-valve:

1. E le ho fokotsa botebo ba mobu o koahelang phaephe,valve ea serurubelehangata e kgethwa bakeng sa phaephe e bophara bo boholo; bothata bo boholo ba valve ea serurubele ke hore poleiti ea serurubele e nka karolo e itseng ea metsi, e leng se eketsang tahlehelo e itseng ea hlooho;

2. Li-valve tse tloaelehileng li kenyelletsali-valve tsa serurubele, li-valve tsa heke, di-valve tsa bolo le di-valve tsa polaka, jj. Mefuta ya di-valve tse sebediswang marangrang a phepelo ya metsi e lokela ho nahanelwa kgethong.

3. Ho lahla le ho sebetsana le li-valve tsa bolo le li-valve tsa polaka ho thata ebile ho bitsa chelete e ngata, 'me ka kakaretso li loketse liphaephe tse nyane le tse mahareng tsa bophara. Valve ea bolo le valve ea polaka li boloka melemo ea valve ea heke e le 'ngoe, khanyetso e nyane ea phallo ea metsi, ho koala ka mokhoa o tšepahalang, ketso e tenyetsehang, ts'ebetso e bonolo le tlhokomelo. Valve ea polaka le eona e na le melemo e tšoanang, empa karolo e fetisang metsi ha se selikalikoe se phethahetseng.

4. Haeba e na le tšusumetso e nyane botebong ba mobu o kwahelang, leka ho kgetha valve ya heke; bophahamo ba valve ya heke ya motlakase valve ya heke e otlolohileng e nang le bophara bo boholo bo ama botebo ba ho kwahela mobu ba phaephe, mme bolelele ba valve ya heke e nang le bophara bo boholo bo eketsa sebaka se bataletseng se nkiloeng ke phaephe mme bo ama tlhophiso ya diphaephe tse ding;

5. Lilemong tsa morao tjena, ka lebaka la ntlafatso ea theknoloji ea ho lahla, tšebeliso ea ho lahla lehlabathe la resin e ka qoba kapa ea fokotsa ts'ebetso ea mechini, ka hona ea fokotsa litšenyehelo, kahoo ho khoneha ha li-valve tsa bolo tse sebelisoang liphaepheng tse bophara bo boholo ho bohlokoa ho hlahlojoa. Ha e le moeli oa boholo ba caliber, o lokela ho nahanoa le ho aroloa ho latela boemo bo itseng.
