Nyaya dzinoverengeka dzinoda kutariswa mukuiswa kwegaskets

Iyo gasket chikamu chekuisa chisimbiso chakamira chinogadzirisa "kumhanya, kuburitsa, kudonha, uye kudonha".Sezvo paine akawanda static sealing zvimiro, zvinoenderana neaya static sealing mafomu, flat gaskets, elliptical gaskets, lens gaskets, cone gaskets, liquid gaskets, O-mhete, uye akasiyana-anozvivharisa gaskets akaonekwa saizvozvo.Iko kuisirwa kwakaringana kwegasket kunofanirwa kuitwa kana iyo flange yekubatanidza chimiro kana yakarukwa yekubatanidza chimiro, iyo static yekuisa chisimbiso pamusoro uye gasket pasina mubvunzo yakatariswa, uye mamwe mavharuvhu akamira.

1. Usati waisa gasket, shandisa girafu ye graphite powder kana graphite powder yakasanganiswa nemafuta (kana mvura) panzvimbo yekuvhara, gasket, thread uye bolt uye nut inotenderera zvikamu.Iyo gasket uye graphite inofanira kuchengetwa yakachena.

2. Iyo gasket inofanira kuiswa panzvimbo yekuisa chisimbiso kuti ive nechepakati, yakarurama, kuti irege kutsauswa, kwete kuwedzera mukati mevhavha yevhavha kana kuzorora pafudzi.Mukati wemukati we gasket unofanirwa kuva wakakura kudarika gomba remukati rekuvhara chisimbiso, uye dhayamita yekunze inofanira kunge iri duku kudarika dhayamita yekunze kwechisimbiso chekuvhara, kuitira kuti ive nechokwadi chokuti gasket yakaenzana.

3. Chikamu chimwe chete chegasket chinobvumirwa kuisa, uye hachibvumirwi kuisa zvidimbu zviviri kana kupfuura pakati pezvisimbiso zvekuisa chisimbiso kuti zvibvise kushayikwa kwepakati pakati pezvikamu zviviri zvekuvhara.

4. Oval gasket inofanira kuiswa chisimbiso kuitira kuti zvindori zvemukati nekunze zvegasi zvibatane, uye migumo miviri ye gasket haifaniri kunge yakabatana nechepasi pe groove.

5. Kuiswa kweO-mhete, kunze kwekuti mhete uye groove inofanira kusangana nezvinodiwa zvekugadzira, kuwanda kwekumanikidza kunofanira kunge kwakakodzera.Iyo flatness yesimbi hollow O-mhete kazhinji 10% kusvika 40%.Iyo yekumanikidza deformation mwero werubha O-mhete ndeye cylindrical.Iyo static yekuisa chisimbiso pachikamu chepamusoro ndeye 13% -20%;iyo static sealing surface ndeye 15% -25%.Kune yakakwira yemukati kudzvanywa, iyo compression deformation inofanirwa kunge yakakwira kana uchishandisa vacuum.Pasi pemamiriro ekusimbisa kuiswa chisimbiso, idiki iyo compression deformation rate, zviri nani, izvo zvinogona kuwedzera hupenyu hweO-ring.

6. Ivhavha inofanira kunge iri panzvimbo yakazaruka isati yaiswa gasket pachifukidziro, kuitira kuti irege kukanganisa kuiswa uye kukuvadza valve.Paunenge uchivhara chivharo, gadzirisa chinzvimbo, uye usabate gasket nekusundidzira kana kudhonza kuti udzivise kutama uye kukwenya kwe gasket.Paunenge uchigadzirisa nzvimbo yevhavha, unofanira kusimudza chifukidzo zvishoma nezvishoma, uye wozochigadzirisa zvinyoro.

7. Kuiswa kwemabhoti kana kuti threaded gaskets inofanira kuva yakadaro zvokuti gaskets iri panzvimbo yakatwasuka (chifukidziro chegasket chekubatanidza ne threaded haifaniri kushandisa zviputi zvepombi kana pane wrench position).Iyo screw tightening inofanira kutora symmetrical, alternate, uye nyangwe maitiro ekushandisa, uye mabhaudhi anofanirwa kunge akasungwa zvizere, akatsvinda uye asingasununguke.

8. Gasket isati yamanikidzwa, kudzvanywa, tembiricha, zvimiro zvepakati, uye gasket zvinhu hunhu zvinofanirwa kunzwisiswa zvakajeka kuti uone pre-yakasimba simba.Iko kusati kwasimba simba kunofanira kuderedzwa zvakanyanya sezvinobvira pasi pemamiriro ezvinhu ekuti muedzo wekumanikidzika haudonhe (yakanyanyisa pre-tightening simba inokuvadza nyore nyore gasket uye kuita kuti gasket irasike kusimba kwayo).

9. Mushure mokunge gasket yakasimbiswa, inofanira kuve nechokwadi kuti kune chigadziko chisati chagadziriswa chechidimbu chekubatanidza, kuitira kuti pave nenzvimbo yekugadzirira kusati kwasimbiswa kana gasket ichidonha.

10. Paunenge uchishanda pakupisa kwepamusoro, mabhoti achaona kupisa kwakanyanya, kuzorora kwekunetseka, uye kuwedzera deformation, zvichiita kuti kuvuza pa gasket uye kunoda kupisa kwekushisa.Pane zvinopesana, pasi pemamiriro ekushisa kwakadzika, mabhoti achaderera uye anoda kutonhora kusunungurwa.Kuomesa kupisa ndiko kudzvanya, kusunungura kutonhora ndiko kuzorora kwekumanikidza, kupisa kupisa uye kutonhora kusunungura kunofanirwa kuitwa mushure mekuchengetedza tembiricha yekushanda kwemaawa makumi maviri nemana.

11. Kana gasket remvura rinoshandiswa pakuisa chisimbiso, nzvimbo yekuvhara inofanira kucheneswa kana kubatwa pamusoro.Iyo yakadzika yekuisa chisimbiso chepamusoro inofanirwa kuenderana mushure mekugaya, uye iyo yekunamatira inofanirwa kushandiswa zvakaenzana (iyo yakanamatira inofanirwa kuenderana nemamiriro ekushanda), uye mweya unofanirwa kubviswa zvakanyanya sezvinobvira.Iyo yekunamatira layer inowanzo 0.1 ~ 0.2mm.Iyo screw thread yakafanana neye flat seal surface.Zvose zviri zviviri zvinosangana zvinofanira kuvharwa.Paunenge uchipinza mukati, inofanira kunge iri panzvimbo yakatwasuka kuti ifambise kubuda kwemhepo.Iyo glue haifanirwe kunge yakawandisa kuti isadeuka uye kusvibisa mamwe mavharuvhu.

12. Paunenge uchishandisa PTFE firimu tepi yekuisa chisimbiso chetambo, panotangira firimu inofanira kutambanudzwa yakaonda uye yakanamirwa kune shinda pamusoro;ipapo tepi yakawandisa painotangira inofanira kubviswa kuti firimu rinamire kune shinda kuita wedge shape.Zvichienderana negejo reshinda, rinowanzokuvadzwa 1 kusvika katatu.Iyo inotenderedza nzira inofanirwa kutevedzera screwing kutungamira, uye iyo yekupedzisira nzvimbo inofanirwa kuenderana neyekutanga nzvimbo;zvishoma nezvishoma dhonza firimu kuita wedge shape, kuitira kuti hupamhi hwefirimu huve hwakaenzana.Usati wapinda mukati, dzvanya firimu kumagumo eshinda kuitira kuti firimu rigone kuvharwa mukati meshinda yemukati pamwe chete ne screw;iyo screwing inofanira kunonoka uye simba rinofanira kunge rakaenzana;usafambise zvakare mushure mekuomesa, uye dzivisa kutendeuka, kana zvisina kudaro zvichava nyore kudonha.
