Ho etsa le ho etsa liteko tsa li-valve tsa mocheso o tlase:

Ts'ebetso e tiileng ea tlhahiso le lisebelisoa tse khethehileng li hlahisoa bakeng sa li-valve tsa mocheso o tlase tse hlahisoang, 'me ho etsoa taolo e tiileng ea boleng bakeng sa ho lokisa likarolo. Ka mor'a phekolo e khethehileng ea mocheso o tlase, likarolo tse entsoeng ka mahlahahlaha li behoa sebakeng se pholileng ka lihora tse 'maloa (lihora tse 2-6) ho lokolla khatello ea kelello, ho netefatsa ts'ebetso ea mocheso o tlase oa thepa, ho netefatsa boholo ba ho qetela, le ho thibela ho lutla. e bakoang ke deformation ea valve ka lebaka la ho fetoha ha mocheso tlas'a boemo ba ho sebetsa ka mocheso o tlaase. Kopano ea valve e fapane le ea valve e tloaelehileng. Likarolo li hloka ho hloekisoa ka thata ho tlosa letheba leha e le lefe la oli ho netefatsa ts'ebetso ea ts'ebeletso.

Lisebelisoa tsa tlhahlobo ea li-valve tsa mocheso o tlase:

1. Sesebelisoa sa tlhahlobo ea valve ea mocheso o tlase

2. Sesebelisoa sa polokelo ea naetrojene e metsi

3. Tanka ea phekolo ea mocheso o tlaase

4. Benche ea teko ea mocheso o tlaase ho etsa bonnete ba hore ts'ebetso ea valve tlas'a maemo a tlaase a mocheso

5. Ba bang

Teko le tlhahlobo ea li-valve tsa mocheso o tlase:

Likarolo tse kholo tsa li-valve tsa mocheso o tlase li tla ba tlas'a kalafo ea mocheso o tlase 'me tlhahlobo ea tšusumetso e tlase ea mocheso e tla etsoa bakeng sa sehlopha se seng le se seng sa lisampole ho netefatsa hore li-valve ha li brittle tlas'a maemo a tlaase a mocheso' me li ka mamella mocheso o tlaase. tshusumetso.

Etsa liteko tse latelang ho valve ka 'ngoe:

1. Teko e tloaelehileng ea matla a khetla ea mocheso;

2. Teko ea ho tiisa mocheso o tloaelehileng le khatello e tlaase;

3. Teko e tloaelehileng ea mocheso le khatello e tlaase ea ho tiisa teko;

4. Teko e tlaase ea mocheso e ka holimo ea tiiso ea moea (e nang le tiiso e ka holimo);

5. Teko e tlaase ea mocheso oa mocheso oa khase, joalo-joalo ho etsa bonnete ba hore valve eohle ea mocheso o tlaase e finyella litlhoko tsa maemo;

6. Etsa phekolo ea mocheso o tlaase bakeng sa likarolo tse kholo le likaroloana 'me u etse tlhahlobo ea mocheso oa mocheso o tlaase bakeng sa sehlopha ka seng sa sampuli ho etsa bonnete ba hore li-valve ha li brittle tlas'a maemo a tlaase a mocheso' me li ka mamella mocheso o tlaase oa mocheso oa mocheso;

7. Li-valve tsa mocheso o tlaase (cryogenic) li tla ba tlas'a phekolo e tlaase ea mocheso le teko ea tšusumetso ho latela litlhaloso tsa thepa tse lumellanang;

8. Mosebetsi oa motlakase o matla haholo. Khanyetso ea conduction pakeng tsa 'mele oa valve le kutu ea valve kapa pakeng tsa ba ka hare le' mele oa valve e ka tlase ho 1 ohm.
