Nzira yekuisa sei valve Kuvhara Gasket

Gaskets chikamu chakajairika chemidziyo.

Factory gasket, wakaiisa nemazvo?

Kana yakaiswa zvisizvo, iyo gasket inogona kukuvadzwa panguva yekushanda kwemidziyo uye inogona kuva nengozi.

Ndezvipi zvishandiso zvinodiwa pakuiswa?

Gadzirira midziyo inotevera usati waisa:

A calibrated torque wrench, hydraulic tightening wrench, kana mamwe maturusi ekusimbisa;

Steel wire brush, brass brass zviri nani;

Ngowani

Goggles

Lubricant

Mamwe maturusi akataurwa nefekitari, nezvimwe

Kuchenesa uye kuomesa fasteners kunoda akasiyana maturusi chaiwo, nekuwedzera, yakajairwa yekuisa michina uye yakachengeteka tsika inofanirwa kuteverwa.

Kuisa matanho

1. Tarisa uye kuchenesa:

Bvisa zvinhu zvese zvekune dzimwe nyika uye marara kubva kune gasket kudzvanya nzvimbo, akasiyana fasteners (mabhaudhi, studs), nzungu uye gaskets;

Tarisa fasteners, nuts uye gaskets kune burrs, kuputika uye zvimwe zvikanganiso;

Tarisa kuti flange pamusoro yakamonyoroka, kana paine radial scratches, kana paine yakadzika maturusi mabump mamaki, kana zvimwe zvinokanganisa zvinokanganisa kugara chaiko kwegasket;

Kana iyo yakaremara yepakutanga inowanikwa, inofanira kutsiviwa nenguva.Kana iwe uine chero kusahadzika nezvekuti ungaitsiva here, unogona kubata mugadziri wechisimbiso nenguva.

2. Rongedza flange:

Gadzirisa chiso cheflange negomba rebhaudhi;

Chero mamiriro ezvinhu asina kunaka anofanira kuziviswa nokukurumidza.

3. Isa gasket:

Tarisa kuti gasket inosangana nehukuru hwakatarwa uye zvinhu zvakatsanangurwa;

Tarisa gasket kuti uone kuti hapana kukanganisa;

Nyatsopinza gasket pakati pemaflange maviri;

Simbisa kuti gasket iri pakati pemafurange;

Usashandise anonamira kana anti-adhesive kunze kwekunge iyo gasket yekumisikidza mirairo ichidaidza;gadzirisa zviso zveflange kuti ive nechokwadi chekuti gasket haina kubaiwa kana kukweshwa.

4. Zora nzvimbo yakasimbiswa:

Mafuta ekuzora akataurwa chete kana anotenderwa anotenderwa kushandiswa panzvimbo yekuzora inotakura simba;

Isa mafuta akakwana kunzvimbo dzinotakura dzeshinda dzese, nzungu uye washer;

Ita shuwa kuti lubricant haina kusvibisa flange kana gasket nzvimbo.

5. Isa uye simbisa mabhaudhi:

Nguva dzose shandisa chishandiso chakakodzera

Shandisa calibrated torque wrench, kana imwe simbi yekusimbisa iyo inodzora basa;

Bvunza nedhipatimendi rehunyanzvi remugadziri wechisimbiso nezve torque zvinodiwa nemitemo;

Paunenge uchisimbisa nati, tevera iyo "cross-symmetrical musimboti";

Simbisa nati zvinoenderana nematanho mashanu anotevera:

1: Kusimbiswa kwekutanga kwemiti yose kunoitwa nemaoko, uye nuts yakakura inogona kusimbiswa neine wrench duku yebhuku;

2: Simbisa nati imwe neimwe kusvika 30% ye torque yese inodiwa;

3: Simbisa nati imwe neimwe kusvika 60% ye torque yese inodiwa;

4: Simbisa nati imwe neimwe zvakare uchishandisa "cross symmetry principle" kusvika 100% ye torque inodiwa yehuni rose;

Cherechedza:Kune yakakura dhayamita flanges, matanho ari pamusoro anogona kuitwa kakawanda

5: Simbisa nzungu dzose imwe neimwe munzira yewachi kanenge kamwe kusvika kune yakazara inodiwa torque.

6. Simbisa mabhaudhi zvakare:

CHERECHEDZA:Bvunza mudhipatimendi wehunyanzvi hwekugadzira zvidhindo kuti uwane nhungamiro uye zano rekusimbisazve mabhaudhi;

Zvisiri-asbestos gaskets uye gaskets zvine zvikamu zverubha zvakashandiswa pakupisa kwepamusoro hazvifanirwe kusimbiswa zvakare (kunze kwekunge zvataurwa neimwe nzira);

Fasteners dzakagamuchira corrosion thermal cycle dzinoda kusimbiswa zvakare;

Kusimbisazve kunofanira kuitwa pane ambient tembiricha uye kumanikidzwa kwemhepo.
