Kuisa chisimbiso pamusoro pezvinhu
Iyo yekuisa chisimbiso ndiyo kiyi yekushanda kumeso kwevhavha. Unhu hwechisimbiso chepamusoro hunoenderana nehupenyu hwebasa revhavha. Kazhinji, iyo yekuisa chisimbiso pamusoro pezvinhu zvinofanirwa kufunga nezve corrosion resistance, abrasion resistance, erosion resistance, oxidation resistance uye zvimwe zvinhu.
Panowanzova nemapoka makuru maviri:
(1) Zvinhu zvakapfava
1, rabha (kusanganisira butadiene rabha, fluorine rabha, nezvimwewo)
2, plastiki (PTFE, naironi, nezvimwewo)
(2) zvisimbiso zvakaomarara
1, alloy yemhangura (yevhavha yakaderera)
2, chromium Stainless simbi (yeyakajairwa high pressure valve)
3, Sitai alloy (yepamusoro tembiricha uye high pressure mavharuvhu uye yakasimba ngura mavharuvhu)
4. Nickel base alloy (ye corrosive media)
Stem material
Dzinde iri pasi pekukweva, kudzvanya uye torsional masimba panguva yekuvhura nekuvhara vharafu, uye iri kutarisana zvakananga nepakati panguva.
Pane ZVIMWE ZVINHU ZVINOITA FRICTION MOVEMENT PAKATI NEKUPAKA, SAKA STEM MATERIAL INOFANIRA KUVA NESIMBA RAKAKWANA UYE IMPACT PAZVINHU ZVAKATAURWA.
Kuoma, corrosion kuramba uye abrasion kuramba, uye yakanaka tekinoroji.
Common stem zvinhu zvinotevera.
Kutanga, carbon steel
Kana ichishandiswa mumvura uye svikiro svikiro ine low pressure uye yepakati tembiricha isingapfuure 300 ℃, A5 yakajairika kabhoni simbi inowanzosarudzwa.
Kune yepakati kudzvanywa uye yepakati tembiricha haipfuure 450 ℃ mvura, chiutsi chepakati, kazhinji sarudza makumi matatu neshanu mhando kabhoni simbi.
Vaviri, alloy simbi
Kune yepakati kudzvanywa uye kudzvanywa kwakanyanya, tembiricha yepakati haipfuure 450 ℃ mvura, chiutsi, mafuta uye mamwe midhiya, kazhinji sarudza 40Cr (chromium simbi).
Nekumanikidza kwakanyanya, tembiricha yepakati haipfuure 540 ℃ mvura, chiutsi uye mamwe midhiya, inogona kusarudza 38CrMo>
Nekumanikidza kwakanyanya, tembiricha yepakati haipfuure 570 ℃ svikiro yepakati, kazhinji sarudza 25Cr2MoVA chromium molybdenum vanadium simbi.
Tatu, Stainless acid simbi
Kune yepakati kudzvanywa uye yakanyanya kudzvanywa, tembiricha yepakati haipfuure 450 ℃ isiri-yakaodza svikiro uye isina kusimba yepakati, inogona kusarudza 1Cr13, 2Cr13, 3Cr13 chromium simbi isina tsvina. Nezve corrosive media, Cr17Ni2, 1Cr18Ni9Ti, Cr18Ni12Mo2Ti, Cr18Ni12Mo3Ti uye imwe stainless acid-resistant simbi uye PH15-7mO kunaya kunoomesa simbi inogona kusarudzwa.
Zvina, simbi inodzivirira kupisa
4Cr10Si2Mo Martensite mhando inopisa-inodzivirira simbi uye simbi inogona kushandiswa kana tembiricha yepakati isiri kupfuura 600 ℃.
4Cr14Ni14W2Mo Austenitic mhando inopisa inodzivirira simbi.
Stem nut zvinhu
Iyo stem nut inoiswa zvakananga kune axial simba rehunde panguva yekuvhura nekuvhara vharafu uye saka inofanirwa kuve neimwe simba. Panguva imwecheteyo, inosungirirwa nehutu, inoda chidimbu chiduku chekuputika, pasina ngura uye kudzivisa chiitiko chekurumwa.
Kutanga, alloy yemhangura
Copper alloy friction coefficient idiki, haina ngura, ndechimwe chezvinhu zvinowanzoshandiswa. Kune PG1.6mpa low pressure valves ZHMN58-2-2 cast brass inogona kushandiswa. Kune PG16-6.4mpa yepakati pressure valve inogona kushandisa ZQ>
Chechipiri, simbi
Kana mamiriro ekushanda asingabvumiri kushandiswa kwemhangura yemhangura, inogona kusarudza 35, 40 quality carbon steel, 2Cr13, 1Cr18Ni9, Cr17Ni2 uye imwe simbi isina asidi-resistant.
Mamiriro ekushanda haabvumirwi kureva zvinotevera.
1, yevharuvhu yemagetsi, valve stem nati ine melon clutch, inoda kupiswa kuti iwane kuoma kwakanyanya kana kuoma kwepamusoro.
2, iyo yekushanda yepakati kana yakapoteredza nharaunda haina kukodzera kusarudzwa kwemhangura yemhangura, yakadai semhangura corrosion yeammonia medium. Paunosarudza simbi stem nuts, kunyanya kukoshesa kunofanira kubhadharwa kune chiitiko chekurumwa kweshinda.
Makore mashoma anotevera ichave iyo indasitiri yevharuvhu yekukurumidza-kumhanya kuvhunduka nguva, iyo yakananga mhedzisiro yekukatyamadzwa uku kukuru ndiyo maitiro aripo epolarization muvharuvhu kabhineti brand camp kuti iwedzere.
Zvinotarisirwa kuti mumakore mashoma anotevera anogona kunyatsorarama mumusika mavharuvhu mabhizinesi haasi akawanda.
Asi iyo indasitiri yevharuvhu iyi yekumhanya-mhanya kuvhunduka ichaunza mikana mikuru, mhedzisiro yekuvhunduka ichaita kuti musika ushande zvine musoro.
