Ho na le mefuta e mengata ea li-valve, empa ts'ebetso ea mantlha e joalo, ke hore, ho hokela kapa ho khaola phallo ea mahareng. Ka hona, bothata bo tiisang ba valve bo hlahelletse haholo.
Ho etsa bonnete ba hore valeve e ka khaola phallo ea mekhahlelo hantle ntle le ho ea, ho hlokahala ho netefatsa hore tiiso ea nala e tiisoa. Ho na le mabaka a mangata a val leapage, ho kopanyelletsa le moralo o hlakileng oa sebopeho, ho na le likarolo tse ntle tsa ho ikopanya, joalo ka mathata ana kaofela a ka lebisa ho tiiso e mpe ea valve. Che, ka hona e theha bothata ba ho tsoa ho hoaya. Ka hona, mahlale a bohlokoa a Valvean ke theknoloji ea bohlokoa tse amanang le ts'ebetso ea valve le boleng, 'me e hloka lipatlisiso tsa tsamaiso le tse hlophisehileng.
Lintho tse tloaelehileng tsa ho tiisa hore li-valve li kenyelletsa mefuta e latelang:
1. NBR
Ho hanyetsa oli ea oli haholo, ho chesa ho hongata haholo, ho hala khanyetso e ntle, ho hanyetsa tšenyeho e matla. Libaka tsa eona ha li khanyetse mocheso o tlase oa mocheso, ha o na khanyetso ea ozone, thepa e litšila ea motlakase, le li-elasticity tse tlase hanyane.
2. Epdm
Karolo ea bohlokoa ka ho fetisisa ea EPDM ke ho hanyetsa ha eona e phahameng e phahameng, ho hanyetsa ha orgon ea Ozone le Corrosion. Kaha EPDM ke ea lelapa la Polyolefin, e na le litšobotsi tse ntle haholo tsa Vulcizanization.
3. Ptfe
PTF e na le khatiso e matla ea lik'hemik'hale, ho hanyetsa oli le likaroneng (ntle le li-Kecshene le likhang tse ntle tsa moea, empa li hanyetsa.
4. Impest ea Iron
Tlhokomeliso: Iron e sebelisetsoa metsi, khase le media ea oli ka mocheso oa≤100°C le khatello ea maikutlo ea≤1.6La.
5. Lello la tlhaho
Tlhokomeliso: Li-alloys tse thehiloeng ho li-pipelimi li na le lipeipi tse nang le mocheso oa -70 ~ 150°C le boenjiniereinte tsa pn≤20.5mpa.
6. Copper Alloy
Copper Alloy o apere khanyetso e ntle mme e loketse metsi le lipeipi tse nang le mocheso ka mocheso≤200℃le khatello ea tlhaho pn≤1.6La.
