1.Wedzera chisimbiso girisi

Kune mavharuvhu asingashandisi girisi yekuisa chisimbiso, funga kuwedzera chisimbiso girisi kuti uvandudze kushanda kwevharuvhu.

2. Wedzera filler

Kuti uvandudze kushanda kwechisimbiso chekutakura kune chivharo chevhavha, nzira yekuwedzera kurongedza inogona kushandiswa.Kazhinji, maviri-layer kana akawanda-layer akasanganiswa mafiritsi anoshandiswa.Kungowedzera huwandu, sekuwedzera nhamba kubva pazvimedu zvitatu kusvika pazvimedu zvishanu, hazvizove nemhedzisiro yakajeka.

3. Tsiva girafu yekuzadza

Iyo inoshandiswa zvakanyanya PTFE kurongedza ine tembiricha yekushanda mukati -20 kusvika +200 ° C.Kana tembiricha ichichinja zvakanyanya pakati pemiganho yepamusoro uye yakaderera, kuita kwayo chisimbiso kuchaderera zvakanyanya, ichakura nekukurumidza uye hupenyu hwayo hupfupi.

Flexible graphite fillers inokunda zvikanganiso izvi uye ine hupenyu hurefu hwebasa.Nokudaro, mamwe mafekitari akashandura zvose PTFE packing kusvika ku graphite packing, uye kunyange mavharuvhu ekudzora achangobva kutengwa akashandiswa mushure mekutsiva PTFE kurongedza ne graphite packing.Zvisinei, hysteresis yekushandisa graphite filler yakakura, uye dzimwe nguva kukambaira kunoitika pakutanga, saka imwe pfungwa inofanira kupiwa kune izvi.

4. Shandura nzira yekuyerera uye isa P2 pamucheto wevhavhavha.

Kana △P yakakura uye P1 yakakura, kuisa chisimbiso P1 zviri pachena kuti kwakaoma pane kuisa chisimbiso P2.Nokudaro, nzira yekuyerera inogona kuchinjwa kubva kuP1 pamagumo evhavha kusvika kuP2 pamagumo evhavha yevhavha, iyo inonyanya kushanda kune mavharuvhu ane simba guru uye kusiyana kukuru kwekumanikidza.Semuenzaniso, mabhero mavharuvhu anowanzo funga kuisa chisimbiso P2.

5. Shandisa lens gasket sealing

Nekuvharwa kwevhavha yepamusoro nechepazasi, kuvharwa kwechigaro chevharuvhu uye miviri yekumusoro neyezasi yevharuvhu.Kana chiri chisimbiso chakati sandara, pasi pekupisa kwepamusoro uye kudzvanywa kwakanyanya, kuita kwekuisa chisimbiso kwakashata, kuchikonzera kuvuza.Iwe unogona kushandisa lens gasket seal panzvimbo, iyo inogona kuwana zvinogutsa mhedzisiro.

6. Dzorera gasket yekuisa chisimbiso

Kusvika pari zvino, akawanda ekuvharisa gaskets achiri kushandisa asbestos board.Pakupisa kwakanyanya, kuita kwekuisa chisimbiso kwakashata uye hupenyu hwesevhisi hupfupi, zvichikonzera kuvuza.Muchiitiko ichi, unogona kushandisa spiral maronda gaskets, "O" zvindori, nezvimwewo, izvo mafekitari akawanda akagamuchira zvino.

7. Simbisa mabhaudhi symmetrically uye chisimbiso nematete gaskets

Muchigadziriso chevharuvhu chine "O" chisimbiso chemhete, kana gaskets gobvu ine deformation yakakura (senge mapeji emhepo) inoshandiswa, kana kudzvanywa kuri kweasymmetrical uye simba riine asymmetrical, chisimbiso chinokanganisika nyore, chakarereka uye chakaremara.Kukanganisa zvakanyanya kuita kwekuisa chisimbiso.

Nokudaro, pakugadzirisa uye kuunganidza rudzi urwu rwevhavha, mabhoti ekumanikidza anofanira kusimbiswa symmetrically (ona kuti haigoni kusimbiswa kamwechete).Zvingave zviri nani kana iyo gobvu gasket inogona kuchinjirwa kuita yakaonda gasket, iyo inogona nyore kuderedza kurerekera uye kuve nechokwadi chekuisa chisimbiso.

8.Kuwedzera hupamhi hwechisimbiso chepamusoro

The flat valve core (senge plug yevharuvhu yevharuvhu yenzvimbo mbiri uye sleeve valve) haina gwara uye inotungamira nzvimbo yakakombama pachigaro chevharuvhu.Kana vharuvhu iri kushanda, iyo yepakati pevhavha inoiswa pasi pesimba re lateral uye inoyerera ichibva kune inflow direction.Sikweya, iyo yakakura iyo gepu rinoenderana revhavha core, iyo yakanyanya kukomba iyi unilateral chiitiko chichava.Pamusoro pezvo, deformation, isina-concentricity, kana diki chamfering yevhavha core sealing surface (kazhinji 30 ° chamfering yekutungamira) inozokonzera kuvhara kwevhavha yepakati kana yava pedyo nekuvhara.Iyo chamfered yekupedzisira kumeso inoiswa pachisimbiso chechigaro chevharuvhu, zvichiita kuti vheji yevhavha isvetuke kana ichivhara, kana kusatombovhara zvachose, ichiwedzera kubuda kwevhavha.

Iyo yakapusa uye inoshanda mhinduro ndeyekuwedzera saizi yevhavha core sealing surface, kuitira kuti iyo shoma dhayamita yevhavha yepakati pekupedzisira kumeso ndeye 1 kusvika 5 mm idiki pane dhayamita yechigaro chevhavha, uye ine nhungamiro yakakwana yekuvimbisa kuti vharafu. core inotungamirwa muchigaro chevharuvhu uye inochengetedza Yakanaka yekuisa chisimbiso pamusoro pekubata.
