Mosebetsi oa Valve Gasket & Guide Guide

Li-gasket tsa valve li etselitsoe ho thibela ho lutla ho bakoang ke khatello, kutu, le katoloso ea mocheso / ho honyela lipakeng tsa likarolo. Le hoja hoo e ka bang tsohle flangedkgokelo's li-valve li hloka li-gaskets, ts'ebeliso ea tsona e khethehileng le bohlokoa li fapana ho ea ka mofuta oa li-valve le moralo. Karolong ena,TWSe tla hlalosa maemo a ho kenya li-valve le khetho ea thepa ea gasket.

I. Tšebeliso e ka sehloohong ea li-gaskets ke lenonyeletsong la flange la likhokahano tsa li-valve.

Li-valve tse sebelisoang hangata

1. Balofo ea Heke
2. Valve ea Globe
3. Butterfly valve(haholo-holo serurubele se concentric le habeli eccentric flanged serurubele)
4. Hlahloba valve

Li-valve tsena, gasket ha e sebelisetsoe ho laola phallo kapa ho tiisa ka hare ho valve ka boeona, empa e kenngoa pakeng tsa li-flange tse peli (pakeng tsa flange ea valve ka boeona le phala ea pipe). Ka ho tiisa liboutu, matla a lekaneng a ho koala a hlahisoa ho theha tiiso e tsitsitseng, e thibelang ho lutla ha seaplane ho hokela. Mosebetsi oa eona ke ho tlatsa likheo tse nyane tse sa leka-lekaneng lipakeng tsa likarolo tse peli tsa tšepe, ho etsa bonnete ba ho tiisa 100% khokahanyong.

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

Li-valve tse ngata li entsoe ka lihlopha tse arohaneng tsa li-valve le likhurumetso bakeng sa tlhokomelo e bonolo ea ka hare (mohlala, ho fetola litulo tsa li-valve, li-valve tsa disc, kapa litšila tse hloekisang), tse ntan'o kopanngoa hammoho. Ho boetse hoa hlokahala gasket khokahanong ena ho netefatsa tiiso e tiileng.

1. Kamano pakeng tsa sekoahelo sa valve le 'mele oa valve oa valve ea heke le valve ea lefats'e hangata e hloka tšebeliso ea gasket kapa O-ring.
2. Gasket sebakeng sena e boetse e sebetsa e le tiiso e tsitsitseng ho thibela bohareng hore bo se ke ba tsoa 'meleng oa valve ho ea sepakapakeng.

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

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

1. Butterfly valve- gasket ea setulo sa valve

• Setulo sa valve ea serurubele ha e le hantle ke ring gasket, e hatelloang ka har'a lebota le ka hare la 'mele oa valve kapa e kenngoa ho pota-potile serurubele.
• Ha serurubeledisce koala, e hatella gasket setulong sa belofo ho etsa tiiso e matla (joalo ka serurubelediscpotoloha).
• Thepa hangata ke rabara (mohlala, EPDM, NBR, Viton) kapa PTFE, e etselitsoeng ho amohela maemo a fapaneng a litaba le mocheso.

2. Valofo ea Ball-Valve Seat Gasket

• Setulo sa valve sa valve ea bolo e boetse ke mofuta oa gasket, eo hangata e entsoeng 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 ka bobeli e le tiiso e tsitsitseng (e amanang le' mele oa valve) le tiiso e matla (e amanang le bolo e potolohang).

IV. Ke li-valve life tseo hangata li sa sebelisoeng le li-gaskets?

1. Li-valve tse cheselitsoeng: 'Mele oa li-valve o cheselitsoe ka kotloloho ho phaephe, ho felisa tlhoko ea li-flange le likhase.
2. Li-valve tse nang le likhokahano tse khoeleng: Hangata li sebelisa ho tiisa ka likhoele (joalo ka theipi e tala kapa sealant), hangata ho felisa tlhoko ea li-gaskets.
3. Li-valve tsa Monolithic: Li-valve tse ling tsa theko e tlaase kapa li-valve tse khethehileng li na le 'mele oa bohlokoa oa li-valve o ke keng oa qhaqha, kahoo o haelloa ke sekoahelo sa valve.
4. Li-valve tse nang le li-O-rings kapa li-gaskets tse phuthetsoeng ka tšepe: Ha li sebelisoa ka khatello e phahameng, mocheso o phahameng kapa o khethehileng-medium, litharollo tse tsoetseng pele tsa ho tiisa li ka nka sebaka sa li-gaskets tse tloaelehileng tse se nang tšepe.

V. Kakaretso:

Valve gasket ke mofuta oa ntho e akaretsang ea ho koala senotlolo, e sebelisoa haholo khokahanong ea lipeipi tsa li-valve tse fapaneng tsa flange, hape e sebelisoa ho tiisa sekoaelo sa li-valve tsa li-valve tse ngata. Ha u khetha, ho hlokahala hore u khethe thepa e nepahetseng ea gasket le ho theha ho ea ka mofuta oa valve, mokhoa oa ho hokahanya, bohareng, mocheso le khatello.
