Hangata valve ea tšireletso e ne e kopana le kahlolo e fosahetseng le tlhokomelo
1. U se ke ua bula ha khatello e boleloa
Lebaka la boemo bona ke hore khatello ea kamehla ha e nepahale. Khatello ea selemo kapa boemo ba hamore e lokela ho lokisoa; Li-disc li khomarela setulong. Valve ea polokeho e lokela ho ba tlhahlobo ea moea kapa tlhahlobo ea metsi khafetsa; Lever ea mofuta oa tšireletso ea lever e khomaretsoe kapa hamore e boima ea sisinyeha. Boima ba 'mele bo lokela ho lokisoa' me leqhubu le tsamaee ka bolokolohi.
2, ka tlase ho khatello e boletsoeng e bulehile
Khatello e kholo ha e nepahale; Botsofali ba selemo elasticity ea fokotseha. Sekoti sa ho lokisa kapa selemo se lokela ho tiisoa hantle.
3. Diski ha e khutlele setulong ka mor'a ho tsoa
Sena se bakoa haholo-holo ke kutu e kobehang ea selemo, boemo ba ho kenya disc ha bo nepahale kapa bo tsitsitse. E lokela ho kopanngoa hape.
4, ho tlola khafetsa ha disc kapa ho thothomela
Lebaka le ka sehloohong ke hore boima ba selemo bo boholo haholo. Seliba se nang le boima bo loketseng se lokela ho sebelisoa ho e-na le hoo; Selikalikoe sa phetoho ha se lokisoe hantle, e le hore khatello e phahame haholo. Boemo ba reng ea ho lokisa bo lokela ho lokisoa; Ho hanyetsa ha pipe ea ho ntša metsi ho kholo haholo, ho fella ka khatello e ngata ea morao ea ho tsoa. Ho hanyetsa ha lipeipi tsa ho ntša metsi ho lokela ho fokotsoa.
5. Khatello e tsoela pele ho phahama ka mor'a ho khathala
Sena ke haholo-holo hobane khetho ea ts'ireletso ea li-valve tsa ts'ireletso ea Xiaoping ea lisebelisoa tsa ts'ireletso, e lokela ho khethoa hape e loketseng valve ea polokeho; Stem bohareng mola kapa selemo mafome, e le hore disc a ke ke a buloa ho bophahamo bo loketseng, lokela ho reassembled bakoang kapa nka sebaka selemo; Haeba ho khaoha ha pipe ea ho qeta ho sa lekana, phala ea ho qeta ho tsamaisana le sebaka se sireletsehileng sa ho tsoa se lokela ho amoheloa.
6, ho lutla
Tlas'a khatello e tloaelehileng ea ho sebetsa ea lisebelisoa, ho phalla pakeng tsa disc le sebaka sa ho tiisa setulo ho feta tekanyo e amohelehang. Lebaka ke: ho na le litšila pakeng tsa diski ea valve le sebaka se tiisang sa setulo. E ka sebelisa sekontiri se phahamisang ho bula valve ka makhetlo a 'maloa, litšila li hlatsuoa; Tšenyo sebakeng sa ho tiisa. E lokela ho lokisoa ka ho sila kapa ho sila ka mor'a ho reteleha ho ea ka tekanyo ea tšenyo. Ho kobeha ha stem, ho thekesela, kapa ho kheloha lever le fulcrum, ho bakang spool le disc misalignment. E lokela ho kopanngoa kapa ho nkeloa sebaka; Elasticity ea selemo e fokotseha kapa e lahleheloa ke elasticity. Mehato e kang ho nkela nako ea selemo sebaka le ho lokisa khatello ea ho bula e lokela ho nkoa.
Litaelo tsa tšebeliso ea li-valve tse nang le fluorine
Litšobotsi tse ka sehloohong tsa valve e nang le fluorine:
