Litiiso tse bonolo li bua ka thepa ea ho tiisa e kentsoeng setulong sa valve e le lisebelisoa tse seng tsa tšepe. Hobane lisebelisoa tse bonolo tsa tiiso li na le elasticity e itseng, litlhoko tsa ho nepahala ha ts'ebetso li batla li le tlase ho feta litiiso tse thata. Re bua ka litšobotsi tsa VTON ho hlalosa phapang pakeng tsa li-valve tsa heke tse tiisitsoeng ka bonolo tse tsoang kantle ho naha le li-valve tsa heke tse tiisitsoeng ka thata.
1. Lisebelisoa tsa ho tiisa
1. Lisebelisoa tsa ho tiisa tsa tse peli li fapane.Li-valve tsa heke tse tiisitsoeng ka bonolohangata li entsoe ka rabara kapa polytetrafluoroethylene. Li-valve tsa heke tse tiisitsoeng ka thata li entsoe ka litšepe tse kang tšepe e sa hloekang.
2. Soft Tial: The pair pair e entsoe ka thepa ea tšepe ka lehlakoreng le leng 'me ka lehlakoreng le leng e bitsoa "soft seal". Mofuta ona oa tiiso o na le ts'ebetso e ntle ea ho tiisa, empa ha e hanyetsane le mocheso o phahameng, ho bonolo ho apara, 'me e na le thepa e fokolang ea mochine. Ka mohlala: rabara ea tšepe; tšepe tetrafluoroethylene, joalo-joalo Ka mohlala, imported rekere setulo tiisovalve ea hekee ea VTON hangata e sebelisoa ka mocheso o ka tlase ho 100 ℃, 'me e sebelisoa haholo bakeng sa metsi a mocheso oa kamore.
3. Tiiso e thata: The pair pair e entsoe ka thepa ea tšepe kapa lisebelisoa tse ling tse thata ka mahlakoreng ka bobeli, tse bitsoang "hard seal". Mofuta ona oa tiiso o na le ts'ebetso e fokolang ea ho tiisa, empa e hanyetsa mocheso o phahameng, e apara ebile e na le thepa e ntle ea mochine. Ka mohlala: tšepe ea tšepe; koporo ea tšepe; graphite ea tšepe; tšepe alloy tšepe; (tšepe mona e ka 'na ea e-ba tšepe e entsoeng ka tšepe, tšepe e entsoeng ka tšepe, tšepe ea alloy e ka' na ea e-ba holim'a metsi, motsoako o fafalitsoeng). Mohlala, valve ea heke ea tšepe e sa hloekang e tsoang kantle ho naha ea VTON e ka sebelisoa bakeng sa mouoane, khase, oli le metsi, joalo-joalo.
2. Theknoloji ea kaho
Tikoloho ea maikemisetso ea indasteri ea mechini e rarahane, eo bongata ba eona e leng mocheso o tlase haholo le khatello e tlase, e nang le khanyetso e kholo le ho bola ho matla ha mahareng. Hona joale theknoloji e ntlafetse, e le hore li-valve tsa heke tse tiisitsoeng ka thata li khothalelitsoe haholo.
Kamano ea boima pakeng tsa litšepe e lokela ho nkoa. Ha e le hantle, valve ea heke e tiisitsoeng ka thata e tšoana le e tiisitsoeng ka bonolo hobane ke tiiso pakeng tsa litšepe. 'Mele oa valve o tlameha ho thatafatsoa, 'me poleiti ea valve le setulo sa valve li tlameha ho lula fatše ho fihlela ho tiisoa. Potoloho ea tlhahiso ea li-valve tsa heke tse tiisitsoeng ka thata ke nako e telele.
3. Sebelisa maemo
Tiiso ea ho tiisa Litiiso tse bonolo li ka fumana ho lutla ha zero, athe litiiso tse thata li ka ba holimo kapa tlase ho latela litlhoko;
Litiiso tse bonolo li hloka ho thibela mollo, 'me ho lutla ho tla hlaha mochesong o phahameng, ha litiiso tse thata li ke ke tsa lutla. Litiiso tse thata tsa li-valve tsa tšohanyetso li ka sebelisoa tlas'a khatello e phahameng, ha litiiso tse bonolo li ke ke tsa sebelisoa. Ka nako ena, valve ea heke e tiisitsoeng ka thata ea VTON ea hlokahala.
Litiiso tse bonolo ha lia lokela ho sebelisoa mecheng ea litaba e itseng e senyang, 'me litiiso tse thata li ka sebelisoa;
4. Maemo a ts'ebetso
Litiiso tse thata li ka ba holimo kapa tse tlase ho latela litlhoko; Litiiso tse bonolo li tlameha ho se che, 'me litiiso tse bonolo li ka fumana litiiso tse phahameng ka bomong. Hobane ka mocheso o tlase haholo, litiiso tse bonolo li tla lutla, athe litiiso tse thata ha li na bothata bona; litiiso tse thata ka kakaretso li khona ho mamella likhatello tse phahameng haholo, ha litiiso tse bonolo li sitoa. Ka mohlala, li-valve tsa heke tsa tšepe tse entsoeng ka ntle ho naha tsa VTON li sebelisa litiiso tse thata, 'me khatello e ka fihla ho 32Mpa kapa 2500LB; litiiso tse bonolo li ke ke tsa sebelisoa libakeng tse ling ka lebaka la ho phalla ha seaplane, joalo ka mecha ea litaba e senyang); qetellong, li-valve tsa tiiso e thata ka kakaretso li theko e boima ho feta litiiso tse bonolo. Ha e le kaho, phapang pakeng tsa tse peli ha e kholo, phapang e kholo ke setulo sa valve, tiiso e bonolo ha e na tšepe, 'me tiiso e thata ke tšepe.
V. Khetho ea lisebelisoa
Khetho ea tiiso e bonolo le e thatali-valve tsa hekee thehiloe haholo-holo holim'a mokhoa oa ho sebetsa, mocheso le khatello. Ka kakaretso, haeba sehare se na le likaroloana tse tiileng kapa se tsofetse kapa mocheso o phahame ho feta likhato tse 200, ho molemo ho sebelisa litiiso tse thata. Mohlala, mouoane oa mocheso o phahameng hangata o pota-potile 180-350 ℃, kahoo ho tlameha ho khethoa valve e thata ea heke.
6. Phapang ka theko le litšenyehelo
Bakeng sa caliber e tšoanang, khatello le thepa, tse tsoang linaheng tse ling li tiisitsoe ka thatali-valve tsa hekeli theko e boima haholo ho feta li-valve tsa heke tse tiisitsoeng ka bonolo tse tsoang kantle ho naha; mohlala, valve ea VTON's DN100 e tsoang kantle ho naha ea tšepe e entsoeng ka tšepe e theko e boima ka 40% ho feta DN100 e tsoang kantle ho naha ea tšepe e tiisitsoeng ka bonolo; haeba li-valve tsa heke tse tiisitsoeng ka thata le li-valve tsa heke tse tiisitsoeng ka bonolo li ka sebelisoa tlas'a maemo a ho sebetsa, ha u nahana ka litšenyehelo, leka ho khetha li-valve tsa heke tse tiisitsoeng ka bonolo tse tsoang kantle ho naha.
7. Phapang bophelong ba tšebeletso
Soft Seal e bolela hore lehlakore le leng la seal pair le entsoe ka thepa e thata haholo. Ka kakaretso, setulo sa tiiso se bonolo se entsoe ka lisebelisoa tse se nang tšepe tse nang le matla a itseng, boima le ho hanyetsa mocheso. E na le ts'ebetso e ntle ea ho tiisa 'me e ka fumana ho lutla ha zero, empa bophelo ba eona le ho ikamahanya le mocheso li batla li fokola. Litiiso tse thata li entsoe ka tšepe 'me li na le ts'ebetso e fokolang ea ho tiisa, le hoja bahlahisi ba bang ba bolela hore ba ka finyella zero leakage.
Monyetla oa litiiso tse bonolo ke ts'ebetso e ntle ea ho tiisa, 'me bothata ke botsofali bo bonolo, ho taboha le bophelo bo khuts'oane ba ts'ebeletso. Litiiso tse thata li na le nako e telele ea tšebeletso, empa ts'ebetso ea tsona ea ho tiisa e batla e fokola ha e bapisoa le litiiso tse bonolo. Mefuta ena e 'meli ea litiiso e ka tlatsana. Mabapi le ho tiisa, litiiso tse bonolo li batla li le betere, empa hona joale ho tiisoa ha litiiso tse thata ho ka boela ha finyella litlhoko tse lumellanang.
Litiiso tse bonolo ha li khone ho fihlela litlhoko tsa ts'ebetso bakeng sa lisebelisoa tse ling tse senyang, empa litiiso tse thata li ka rarolla bothata bona!
Mefuta ena e 'meli ea litiiso e ka tlatsana. Mabapi le ho tiisa, litiiso tse bonolo li batla li le betere, empa hona joale ho tiisoa ha litiiso tse thata ho ka boela ha finyella litlhoko tse lumellanang!
