Nzira yekuchengetedza yevhavha packing:

Iwo mafirita epurojekiti iyi anonyanya kuve nezvinhu zviviri zvinotevera: PTFE uye yakapfava graphite.

Kana yachengetwa, yakavharwa muhomwe kana mubhokisi. Chengetedza zvakanaka muimba yakaoma uye ine mhepo, dzivisa chiedza chezuva. Chenjerera kumhepo panguva yekuchengetedza kwenguva refu, uye chengetedza tembiricha yenzvimbo yekuchengetera kuti isapfuure 50 ° C kudzivirira guruva rakawandisa. Kana guruva rakasungirirwa pamusoro pekuzadza rinobviswa uye rinoshandiswa, ripute nemucheka wakachena.

Valve packing kutsiva nzira:

Zvisimbiso zvekurongedza zvinoumbwa sezvinotevera: 1). Kurongedza compression nati, 2) Swing bhaudhi, 3) Fixed pini, 4) Kurongedza, 5) Kurongedza sleeve, 6) Kurongedza kumanikidza ndiro (dzimwe nguva 5 uye 6 zvikamu zvakakosha zvinoenderana nekuumbwa uye Yakatemerwa nemamiriro akasiyana ekushanda, iro basa rese. zvakafanana neiyo yekuparadzana)

Matanho ekurongedza chisimbiso anotsiva ndeaya anotevera:

1. Shandisa chipanera kuti ubvise 1) kurongedza kusungirirwa nut uye kuisimudza 5) sleeve yekuputira yekutakura uye 6) ndiro yekuputira yekutakura, ichisiya nzvimbo yekushanda kwekutsiva kurongedza.

2. Shandisa flat-blade screwdriver kana zvimwe zvimedu zvesimbi kuti ubvise kurongedza kwepakutanga uye kuchitsiva neimwe itsva. Kana kurongedza kurongedza kuchishandiswa, paunenge uchiisa kurongedza kutsva, teerera kuti kutungamira kwekucheka kwekucheka kunofanira kuderedzwa ne 90 ~ 180 °, uye kona inosanganisirwa inofanira kudzokororwa paviri. Usave nekupindirana kwakawanda munzira imwechete sezvakaratidzwa mumufananidzo;

3. Mushure mekuisa chiyero chakakodzera chekutakura, dzorera 5) kutakura gland uye 6) kurongedza kusungirirwa kweplate yekuisa. Paunenge uchiisa, teerera kune nzvimbo yechisimbiso chekuisa uye 6 ~ 10mm yakadzika mukati mevhavhavhavhavhavha (kana 1.5 ~ 2 nguva yehukobvu hwekutakura) sechiratidzo chekuisa (Sezvinoratidzwa pasi apa).

4. Dzosera 1). Packing compression nut, 2) Simbisa nzvimbo yekuisa yejoint bolt kusvika yasvika 20% yekumisikidzwa kwekutakura.

5. Mushure mokuzadzisa matanho ari pamusoro apa, itai kuongorora kunokosha pavhavha yakatsiva kutakura mukushandiswa kunotevera kuti uone kana zvichidiwa kuwedzera kutakura kwekutakura.

Tsanangudzo: Mirayiridzo yekusimbisazve uye kutsiva kurongedza pasi pekumanikidzwa.

Mabasa anotevera maoparesheni ane njodzi. Ndapota usazviedza zvishoma kana zvisingakoshi. Ndokumbira uteedzere gwaro iri rekutungamira panguva yematanho ekushanda:

1. Mushandi anofanira kuva nekumwe kunzwisisa kwemichina nemavharuvhu. Pamusoro pezvishandiso zvinodikanwa zvemuchina, mushandisi anofanira kupfeka magirovhosi anodzivirira kupisa, nhovo dzechiso, uye ngowani.

2. Ivhavha yakazarurwa zvakakwana kusvikira chisimbiso chepamusoro chevhavha chinyatsoshanda. Nheyo yekutonga ndeyekuti iyo valve yekushandisa michina haigone kusimudza tsinde yevharuvhu, uye hapana ruzha rusina kujairika pahunde yevharuvhu.

3. Mushandi anofanira kunge ari parutivi rwechisimbiso chekuisa chisimbiso kana zvimwe zvigadziro zvisingagoni kufungidzira. Zvinorambidzwa zvachose kutarisana nechinzvimbo chekutakura. Kana kurongedza kunoda kusimbiswa, shandisa wrench kuti usimbise 1) Packing compression nut, 2 ~ 4 mazino, mativi ose maviri ekugadzirisa kusungirirwa nut Inoda kuurayiwa, kwete rutivi rumwe chete.

4. Apo kurongedza kunoda kuchinjwa, shandisa chipanera kuti usunungure 1) Packing compression nut, 2 ~ 4 mazino, kurongedza kusungirirwa nut kumativi ose maviri kunoda kuurayiwa zvakasiyana. Munguva iyi, kana pane mhinduro isina kujairika kubva pachitsiko chevharuvhu, pakarepo mira uye udzorere nati, ramba Uchishandisa dhizaini yekushanda kwevhavha maererano nemaitiro ari mudanho rechipiri, zadzisa chisimbiso pahunde yevharuvhu kusvikira yanyatsoshanda, uye ramba uchitsiva kurongedza. Iyo yekutsiva kurongedza pasi pekumanikidzwa haibvumidzwe kuchinjwa zvachose kunze kwemamiriro akakosha. Huwandu hwekutsiva ndeye 1/3 yehuwandu hwekurongedza. Kana zvisingabviri kutonga, matatu epamusoro packings anogona kutsiviwa. Mushure mekugadzika kwapera, dzorera kuisirwa kwe5 packing press sleeve uye 6 packing press plate. Paunenge uchiisa, teerera kune chinzvimbo chechisimbiso chekurongedza uye 6 ~ 10mm yakadzika mukati mevhavhavhavhavhavha (kana 1.5 ~ 2 nguva ukobvu hwekurongedza) senzvimbo yekumisikidza. Dzorera 1). Packing compression nut, 2) Simbisa nzvimbo yekuisa yejoint bolt kusvika 25% yekumanikidza kwakanyanya kwekurongedza. Kana pasina kudonha muvharuvhu yepasi stem packing, inokwana. Kana paine kuvuza, tevera maitiro ari mumatanho 2 uye 3 kuomesa.

5. Matanho ese ekushanda ari pamusoro apa ndeekusimudza mavharuvhu ekusimudza tsinga akadai se: rising stem gedhi vharafu, rising stem stop valve, zvichingodaro, hazvishande kune rima dzinde uye risingasimudze dzinde mavharuvhu akadai se: dema stem gedhi vharafu, rima stem stop valve, butterfly valve, Ball valves uye zvichingodaro.
