Karolo ea bohlokoa ka ho fetisisa ea tiiso ea valve ke setulo sa ho tiisa sa valve, seo hape se bitsoang lesale la ho tiisa.Ke karolo ea bohlokoa ea para e koalang li-valve, e amanang ka kotloloho le sehare se phaepheng.Mecha ea phatlalatso ea liphaephe e kenyelletsa metsi, khase, lintho tse nyenyane, acid le alkaline, joalo-joalo. Li-valve li tlameha ho sebelisa lisebelisoa tse fapaneng ho ikamahanya le mecha ea litaba e fapaneng.Joale ke mehato efe ea ho itšireletsa ha u khetha li-valve seal?

1. Thepa ea tensile.Thepa ea tensile ke thepa ea pele e lokelang ho nahanoa bakeng sa thepa ea ho tiisa, ho kenyelletsa: matla a ho tiea, khatello ea maikutlo, bolelele nakong ea khefu le deformation e sa feleng nakong ea khefu. Litiiso tse tloaelehileng tsa rabara keEPDMle NBR, joalo-joalo.

2. Ho thatafala.E bontša bokhoni ba thepa ea ho tiisa ho hanela ho kenella ha matla a ka ntle, e leng e 'ngoe ea thepa ea motheo ea thepa ea ho tiisa.Ho thatafala ha thepa ho amana le thepa e 'ngoe ho isa tekanyong e itseng.Ha boima bo phahame, matla a maholoanyane, bolelele bo fokotseha, le ho hanyetsa ho apara.Ho molemo, le ho mpefala ha mocheso o tlase o hanyetsa.
3. Khatello ea khatello.Litiiso tsa rabara hangata li maemong a petelitsoeng, 'me thepa ena e amana ka kotloloho le ho tšoarella ha matla a tiiso ea sengoloa se tiisitsoeng. 4. Lintho tse hanyetsanang le kutu.Thepa e tiisang oli kapa e manganga mahareng, ka linako tse ling e kopana le mecha ea litaba e senyang joalo ka asiti le alkali indastering ea lik'hemik'hale.Ntle le ho senyeha ha mecha ea litaba, e boetse e baka ho atolosoa le ho fokotseha ha matla ka mocheso o phahameng.PTFE.

5. Khahlanong le botsofali.Lintho tse thibelang botsofali tse thibelang botsofali li tla baka ho senyeha ha ts'ebetso ka mor'a ho angoa ke oksijene, ozone, mocheso, leseli, mongobo le khatello ea mochine, e bitsoang botsofali ba thepa ea ho tiisa.

Haeba u thahasella litaba tse ka holimo kapa u batla ho ba le kutloisiso e eketsehileng ea li-valve seal, ka kopoiteanye le ronabakeng sa lipuisano tse ling
