Haeba bophara bo le boholo haholo, ho tla ba thata haholo ho kenya le ho tiisa khokahano. Li-valve tsa khokahano ea flange li bonolo ho li kenya le ho li qhaqha, empa li kholo ebile li theko e boima ho feta li-valve tse nang le khoele, kahoo li loketse likhokahano tsa liphaephe tsa bophara le khatello e fapaneng ea liphaephe. ​​Likhokahano tse helelitsoeng li loketse maemo a boima ba mojaro 'me li tšepahala ho feta likhokahano tsa flange. Leha ho le joalo, ho thata ho qhaqha le ho kenya li-valve tse helelitsoeng hape, kahoo tšebeliso ea tsona e lekanyelitsoe maemong ao hangata li ka sebetsang ka mokhoa o tšepahalang nako e telele, kapa moo maemo a mosebetsi a leng boima 'me mocheso o le holimo;

1.4 Khetho ea thepa ea valve

Ha o kgetha thepa bakeng sa ntlo ya valve, dikarolo tsa kahare le bokahodimo ba ho kwala, ntle le ho nahana ka thepa ya mmele (mocheso, kgatello) le thepa ya dikhemikhale (ho bola) ya sesebediswa se sebetsang, bohloeki ba sesebediswa (boteng kapa ho ba siyo ha dikarolwana tse tiileng) le bona bo lokela ho nahanelwa. Ho feta moo, o tlameha ho boela o shebe melao e amehang ya naha le lefapha la basebedisi. Kgetho e nepahetseng le e utlwahalang ya thepa ya valve e ka netefatsa bophelo ba tshebeletso bo theko e tlase ka ho fetisisa le tshebetso e ntle ka ho fetisisa ya valve. Tatellano ya kgetho ya thepa ya mmele wa valve ke: tshepe e lahletsweng ka tshepe-khabone-tshepe e sa tjheseng, mme tatellano ya kgetho ya thepa ya lesale la ho kwala ke: tshepe ya rabara-koporo-alloy-F4;

2.1Valve ea heke

Valve ea heke e bolela valve eo 'mele oa eona oa ho bula le ho koala (poleiti ea valve) o tsamaisoang ke kutu ea valve 'me o tsamaea holimo le tlase holim'a sekoahelo sa valve ho hokahanya kapa ho khaola kanale ea mokelikeli. Ha e bapisoa le li-valve tsa ho emisa, li-valve tsa heke li na le ts'ebetso e betere ea ho koala, khanyetso e nyane ea mokelikeli, boiteko bo fokolang ba ho bula le ho koala, 'me li na le ts'ebetso e itseng ea ho lokisa. Ke e 'ngoe ea li-valve tsa ho emisa tse sebelisoang haholo. Bothata ke hore e kholo ka boholo 'me e rarahane ka sebopeho ho feta valve ea ho emisa. Sebaka sa ho koala se bonolo ho se apara 'me se thata ho se hlokomela, kahoo hangata ha sea lokela ho thijoa. Ho ea ka boemo ba khoele kutung ea valve ea valve ea heke, e arotsoe ka mekhahlelo e 'meli: mofuta oa kutu o bulehileng le mofuta oa kutu o patiloeng. Ho ea ka litšobotsi tsa sebopeho sa heke, e ka aroloa ka mefuta e 'meli: mofuta oa wedge le mofuta o bapileng.

2.2Valve ea ho emisa

Valve ea lefats'e ke valve e koalang e theohelang tlase. Likarolo tsa ho bula le ho koala (li-disc tsa valve) li tsamaisoa ke kutu ea valve ho ea holimo le tlase ho latela axis ea setulo sa valve (bokaholimo ba ho koala). Ha li bapisoa le li-valve tsa heke, li na le ts'ebetso e ntle ea taolo, ts'ebetso e mpe ea ho koala, sebopeho se bonolo, tlhahiso le tlhokomelo e bonolo, khanyetso e kholo ea mokelikeli, le theko e tlase. Ke valve ea ho emisa e sebelisoang hangata, e sebelisoang hangata liphaepheng tse bophara bo mahareng le bo bonyenyane.

2.3 Valve ea bolo

Karolo ea ho bula le ho koala ea valve ea bolo ke bolo e nang le lesoba le chitja. Bolo e potoloha le kutu ea valve ho bula le ho koala valve. Valve ea bolo e na le sebopeho se bonolo, ho bula le ho koala kapele, ts'ebetso e bonolo, boholo bo bonyenyane, boima bo bobebe, likarolo tse 'maloa, ho hanyetsa mokelikeli o monyane, ho koala hantle le tlhokomelo e bonolo.
