Ingxenye ebaluleke kakhulu ye-valve seal yisihlalo sokuvala se-valve, ebizwa nangokuthi iringi yokuvala.Iyingxenye ebalulekile yepheya yokuvala ama-valve, ethintana ngqo nendawo esemgqeni.Imithombo yezindaba esendleleni ihlanganisa amanzi, igesi, i-particle, i-asidi kanye nezinto ezine-alkaline, njll. Ama-valve seal kufanele futhi asebenzise izinto ezihlukahlukene ukuze azivumelanise nemidiya ehlukene.Ngakho-ke yiziphi izinyathelo zokuphepha zokukhetha ama-valve seal?

1. Izakhiwo ze-tensile.Izakhiwo eziqinile yizinto zokuqala okufanele zicatshangelwe ukuze kuhlanganiswe izinto zokuvala, okuhlanganisa: amandla aqinile, ukucindezeleka okuqinile, ubude ngesikhathi sekhefu kanye nokuguqulwa unomphela ngesikhathi sekhefu.I-EPDMkanye ne-NBR, njll.

2. Ukuqina.Ibonisa ikhono lempahla yokuvala ukuze imelane nokungena kwamandla angaphandle, okubuye kube enye yezinto eziyisisekelo zezinto zokuvala.Ukuqina kwempahla kuhlobene nezinye izakhiwo ngezinga elithile.Ukuphakama kokuqina, amandla amakhulu, ukunwebeka kuncane, nokumelana nokuguga.Okungcono, futhi okubi kakhulu ukumelana nokushisa okuphansi.
3. Ukucindezela kokucindezela.Izigxivizo zenjoloba ngokuvamile ziba sesimweni sokucindezelwa, futhi lesi sakhiwo sihlobene ngokuqondile nokuqina kwekhono lokuvala le-athikili evaliwe. 4. Izinto ezikwazi ukumelana nokugqwala.Izinto zokuvala ezimelana nowoyela noma ukumelana nendawo okumaphakathi, ngezinye izikhathi ezithinta imidiya ezonakalisayo njenge-asidi ne-alkali embonini yamakhemikhali.Ngaphezu kokugqwala kule mithombo yezindaba, iphinde ibangele ukwanda kanye nokuncipha kwamandla emazingeni okushisa aphezulu.Izimpawu ezivamile zokulwa nokugqwala ziyiI-PTFE.

5. Anti-ukuguga.Izinto zokuvala ukumelana nokuguga zizodala ukuwohloka kokusebenza ngemuva kokuthintwa umoya-mpilo, i-ozone, ukushisa, ukukhanya, umswakama kanye nokucindezeleka kwemishini, okubizwa ngokuthi ukuguga kwezinto zokuvala.

Uma unentshisekelo kokuqukethwe okungenhla noma ufuna ukuqonda okwengeziwe ngama-valve seal, sicelaXhumana nathiukuze uthole ukubonisana okwengeziwe
