Tataiso ea Mosebetsi oa Gasket ea Valve le Ts'ebeliso

Li-gasket tsa li-valve li etselitsoe ho thibela ho lutla ho bakoang ke khatello, mafome, le katoloso/ho honyela ha mocheso lipakeng tsa likarolo. Leha hoo e ka bang tsohle li flangekhokahano's Li-valve li hloka li-gasket, ts'ebeliso ea tsona e ikhethang le bohlokoa li fapana ho latela mofuta oa li-valve le moralo. Karolong ena,TWSe tla hlalosa maemo a ho kenya di-valve le kgetho ya thepa ya gasket.

I. Tšebeliso ea mantlha ea li-gasket ke ho flange joint ea likhokahano tsa li-valve.

Valve e sebelisoang haholo

1. Valve ea Heke
2. Valve ea Lefatše
3. Valve ea serurubele(haholo-holo valve ea serurubele e nang le sebopeho se otlolohileng le se habeli se sa bonahaleng)
4. Valve ea ho hlahloba

Li-valve tsena, gasket ha e sebelisoe bakeng sa taolo ea phallo kapa ho koala ka har'a valve ka boeona, empa e kenngoa pakeng tsa li-flange tse peli (pakeng tsa flange ea valve ka boeona le flange ea phaephe). Ka ho tiisa liboutu, matla a lekaneng a ho khomarela a hlahisoa ho etsa tiiso e sa fetoheng, e thibelang ho lutla ha seaplane khokahanong. Mosebetsi oa eona ke ho tlatsa likheo tse nyane tse sa lekanang pakeng tsa libaka tse peli tsa flange tsa tšepe, ho netefatsa ho koaloa ha 100% khokahanong.

II.Tšebeliso ea Gasket ka Valve "Sekoahelo sa Valve"

Li-valve tse ngata li entsoe ka 'mele ea li-valve le likoahelo tse arohaneng bakeng sa tlhokomelo e bonolo ea kahare (mohlala, ho nkela litulo tsa li-valve sebaka, li-valve tsa disc, kapa ho tlosa lithōle), tse tlang ho kopanngoa hammoho. Gasket le eona ea hlokahala khokahanong ena ho netefatsa tiiso e tiileng.

1. Kgokelo pakeng tsa sekoahelo sa valve le mmele wa valve wa valve ya heke le valve ya globe hangata e hloka tshebediso ya gasket kapa O-ring.
2. Gasket e boemong bona e boetse e sebetsa e le tiiso e sa fetoheng ho thibela sehatsetsi ho dutla ho tswa mmeleng wa valve ho ya sepakapakeng.

III. Gasket e khethehileng bakeng sa mefuta e itseng ea li-valve

Li-valve tse ling li kenyelletsa gasket e le karolo ea kopano ea tsona ea ho tiisa ea mantlha, e etselitsoeng ho kopanngoa ka har'a sebopeho sa li-valve.

1. Valve ea serurubele- gasket ea setulo sa li-valve

• Setulo sa valve ea serurubele ha e le hantle ke gasket ea lesale, e hatelloang leboteng le ka hare la 'mele oa valve kapa e kenngoa ho potoloha disc ea serurubele.
• Ha serurubelediskiha e kwala, e hatella gasket ea setulo sa valve ho etsa tiiso e matla (joalokaha serurubelediskie potoloha).
• Hangata thepa ena ke rabara (mohlala, EPDM, NBR, Viton) kapa PTFE, e etselitsoeng ho amohela maemo a fapaneng a media le mocheso.

2. Valve ea Bolo-Gasket ea Setulo sa Valve

• Setulo sa valve sa valve ea bolo le sona ke mofuta oa gasket, hangata se entsoe ka thepa e kang PTFE (polytetrafluoroethylene), PEEK (polyetheretherketone), kapa polasetiki e matlafalitsoeng.
• E fana ka tiiso pakeng tsa bolo le 'mele oa valve, e sebetsang e le tiiso e sa fetoheng (ha e bapisoa le 'mele oa valve) le tiiso e matla (ha e bapisoa le bolo e potolohang).

IV. Ke li-valve life tse sa sebelisoeng hangata ka li-gasket?

1. Li-valve tse tjheseletsoeng: 'Mele oa li-valve o tjheselitsoe ka ho toba ho phaephe, e leng se felisang tlhoko ea li-flange le li-gasket.
2. Li-valve tse nang le likhokahano tse nang le likhoele: Hangata li sebelisa ho koala ka likhoele (joalo ka theipi ea thepa e tala kapa sealant), ka kakaretso ho felisa tlhoko ea li-gasket.
3. Li-valve tsa monolithic: Li-valve tse ling tsa bolo tse theko e tlase kapa li-valve tse khethehileng li na le 'mele oa valve o ke keng oa qhaqhoa, kahoo ha o na gasket ea sekoahelo sa valve.
4. Li-valve tse nang le masale a O kapa li-gasket tse phuthetsoeng ka tšepe: Litšebelisong tse nang le khatello e phahameng, mocheso o phahameng, kapa tse khethehileng tse mahareng, litharollo tse tsoetseng pele tsa ho tiisa li ka nka sebaka sa li-gasket tse tloaelehileng tse seng tsa tšepe.

Kakaretso ea V.:

Gasket ea valve ke mofuta oa karolo e akaretsang ea ho koala senotlolo, e sebelisoa haholo khokahanong ea liphaephe tsa li-valve tse fapaneng tsa flange, 'me e sebelisoa hape ho koaloeng ha sekoahelo sa valve ea li-valve tse ngata. Khethong, ho hlokahala ho khetha thepa e loketseng ea gasket le sebopeho ho latela mofuta oa valve, mokhoa oa khokahano, bohareng, mocheso le khatello.
