Lisebelisoa tsa ho tiisa tse sebelisoang hangata bakeng sa li-valve ke life?

Ho na le mefuta e mengata ea li-valve, empa mosebetsi oa mantlha o ts'oana, ke hore, ho hokahanya kapa ho khaola phallo e mahareng. Ka hona, bothata ba ho koala ha valve bo hlahella haholo.

Ho netefatsa hore valve e ka khaola phallo e mahareng hantle ntle le ho dutla, ho hlokahala ho netefatsa hore tiiso ea valve e phetse hantle. Ho na le mabaka a mangata a ho dutla ha valve, ho kenyeletsoa moralo o sa utloahaleng oa sebopeho, bokaholimo ba ho koala bo nang le sekoli, likarolo tse tlamang tse hlephileng, ho lekana ho hlephileng pakeng tsa 'mele oa valve le bonnet, jj. Mathata ana kaofela a ka lebisa ho koaloeng ho fokolang ha valve. Kahoo, ho baka bothata ba ho dutla. Ka hona, theknoloji ea ho tiisa valve ke theknoloji ea bohlokoa e amanang le ts'ebetso le boleng ba valve, 'me e hloka lipatlisiso tse hlophisitsoeng le tse tebileng.

Lisebelisoa tse sebelisoang haholo bakeng sa ho tiisa li-valve li kenyelletsa mefuta e latelang:

1. NBR

Ho hanyetsa oli hantle haholo, ho hanyetsa ho tsofala ho hoholo, ho hanyetsa mocheso hantle, ho khomarela ho matla. Mathata a eona ke ho hanyetsa mocheso o tlase, ho hanyetsa ozone hampe, thepa e fokolang ea motlakase, le ho tenyetseha ho fokolang hanyane.

2. EPDM

Tšobotsi ea bohlokoa ka ho fetisisa ea EPDM ke ho hanyetsa ha eona ho phahameng ka ho fetisisa ha oxidation, ho hanyetsa ozone le ho hanyetsa mafome. Kaha EPDM ke ea lelapa la polyolefin, e na le litšobotsi tse ntle tsa vulcanization.

3. PTFE

PTFE e na le khanyetso e matla ea lik'hemik'hale, e hanyetsa oli le li-solvent tse ngata (ntle le li-ketone le li-ester), khanyetso e ntle ea boemo ba leholimo le khanyetso ea ozone, empa e hanyetsa serame hantle.

4. Tšepe e lahliloeng

Ela Hloko: Tšepe e entsoeng ka tšepe e sebelisetsoa metsi, khase le oli e nang le mocheso oa≤100°C le kgatello e tloaelehileng ya≤1.6mpa.

5. Motsoako o thehiloeng ho nikeli

Ela Hloko: Metswako e kopantsoeng e thehiloeng ho nikeli e sebediswa bakeng sa diphaephe tse nang le mocheso wa -70~150°C le PN ea khatello ea boenjiniere≤20.5mpa.

6. Motsoako oa koporo

Motsoako oa koporo o na le khanyetso e ntle ea ho tsofala 'me o loketse liphaephe tsa metsi le mouoane tse nang le mocheso o phahameng.≤200℃le khatello e tloaelehileng ea PN≤1.6mpa.
