Ho na le holim'a liheke tse peli tse tiisitsoeng, mokhoa o atileng haholo oa ho koala li-valve tsa heke ho etsa li-wedge tse peli, angle ea wedge e fapana le li-parameter tsa valve, hangata ke 50, mocheso ha o phahame ke 2 ® 52 *.Belofo ea heke ea Wedge e ka etsoa ka botlalo, e bitsoang heke e thata;hape ho etsoa ho hlahisa deformation nyenyane ea heke, e le hore ho ntlafatsa tshebetso ya eona, ho etsa sealing holim'a angle kheloha hlaha nakong ea ho sebetsa, heke ena e bitsoa flexible heke.
Letoto lena la lihlahisoa le na le litšobotsi tse latelang:
1.Sehlopha sa li-valve se amohela sebopeho sa sebopeho se loketseng litlhoko tsa ts'ebetso ea lesela;Sekoti se ka hare sa 'mele oa valve, sekoahelo sa valve le heke, bokaholimo bo ka ntle ba kutu ea valve le likarolo tse ling tse amanang ka kotloloho le bohareng, kaofela li kentsoe FEP(F46) kapa PCTFE(F3) le lipolasetiki tse ling tsa fluorine;
2. Ho hanyetsa mokelikeli o monyenyane, sebaka se tiisang ka khoholeho ea mobu Chong brush medium le e nyenyane
3.Open le koala boiteko bo eketsehileng.
4.Mecha e phallang e sa thibeloe, e se nang senya ha e fokotse khatello.
5.Foroha sebopeho se bonolo, bolelele bo khutšoanyane, mokhoa o motle oa ho etsa lihlahisoa, o sebetsang ho mefuta e mengata ea.
6.The medium e ka feta ka valve ea heke ka tsela leha e le efe ho tloha mahlakoreng ka bobeli, e loketseng sesebelisoa sa ho bula le ho koala phapeng moo tataiso e bohareng e ka fetohang.
7.PFA/FEP line, e nang le botsitso bo phahameng ba lik'hemik'hale, e ka sebelisoa ho mecha efe kapa efe e matla e senyang ntle le "tšepe ea alkali e qhibilihisitsoeng le element fluorine".
