2022-08-17
Phapang pakeng tsa tiiso e bonolo le tiiso e thata ea valve Ho phaella ho valve e thibelang ho bola, valve e akaretsang e bua ka spool kapa setulo sa e 'ngoe ea lisebelisoa tse peli tse se nang tšepe (haholo-holo PTFE, rabara, joalo-joalo) ea valve. Matla a ho tiisa ha valve e bonolo ea tiiso e molemo, empa ha ho kenngoa liphaephe, ho hloekisa tsamaiso ho ka siea litšila tse ngata kapa tse fokolang (tse kang li-welding slag, li-filings tsa tšepe, joalo-joalo), li phalla ka har'a valve e laolang, ho bonolo ho phunya. setulo sa tiiso kapa spool, e le hore palo ea ho lutla e eketsehe, ho tšepahala ha tiiso ho fokola. Ka hona, khetho ea sebopeho sa tiiso e bonolo e tlameha ho nahanoa ka tlhoekiso e mahareng le phaephe e tiileng ea ho phunya pele e sebetsa. Setiiso se bonolo sa Valve le phapang ea tiiso e thata: (1) Setiiso se bonolo Ho phaella ho valve e thibelang ho bola, valve ea kakaretso e bonolo e bua ka spool kapa setulo sa e 'ngoe ea lisebelisoa tse peli tseo e seng tsa tšepe (haholo-holo PTFE, rabara, joalo-joalo. ) mofuta o tiisitsoeng oa valve. Matla a ho tiisa ha valve e bonolo ea tiiso e molemo, empa ha ho kenngoa lipeipi, ho hloekisa tsamaiso ho ka siea litšila tse ngata kapa tse fokolang (tse kang li-welding slag, li-filings tsa tšepe, joalo-joalo), li phalla ka har'a valve e laolang, ho bonolo ho phunya. setulo sa tiiso kapa spool, e le hore palo ea ho lutla e eketsehe, ho tšepahala ha tiiso ho fokola. Ka hona, khetho ea sebopeho sa tiiso e bonolo e tlameha ho nahanoa ka tlhoekiso e mahareng le phaephe e tiileng ea ho phunya pele e sebetsa. (2) Hard seal Setiiso se thata le ho beoa ha alloy e sa sebetseng ke khetho e ntle bakeng sa ho khaola li-valve. Ka tsela ena ha ho nahanoa ka tiiso le ho nahana ka bophelo ba ts'ebeletso le ho ts'epahala, leha index ea fektheri e le 10-6 ~ 10-8 feela, e ke ke ea fihlela phello ea ho lutla ha tiiso ea zero, empa ho lekana ho fihlela litlhoko tsa ho khaola ka thata, 'me e tšoarella, ho ea ka pono ea moruo e na le litšenyehelo tse ngata.
