Gasket ndi gawo losindikiza lokhazikika lomwe limathetsa "kuthamanga, kutulutsa, kudontha, ndi kutuluka".Popeza pali zida zambiri zosindikizira, molingana ndi mawonekedwe osindikizira awa, ma gaskets athyathyathya, ma elliptical gaskets, ma lens gaskets, ma cone gaskets, ma gaskets amadzimadzi, mphete za O, ndi ma gaskets osiyanasiyana odzisindikiza adawonekera moyenerera.Kuyika kolondola kwa gasket kuyenera kuchitika pomwe mawonekedwe olumikizirana ndi flange kapena mawonekedwe olumikizana ndi ulusi, malo osindikizira osasunthika ndi gasket mosakayikira amafufuzidwa, ndipo mbali zina za valve zili bwino.
1. Musanayike gasket, gwiritsani ntchito ufa wa graphite kapena graphite ufa wothira mafuta (kapena madzi) pamtunda wosindikizira, gasket, ulusi ndi bolt ndi nati zozungulira.Gasket ndi graphite ziyenera kukhala zoyera.
2. Gasket iyenera kuikidwa pamtunda wosindikizira kuti ikhale pakati, yolondola, kuti isasokonezedwe, kuti isapitirire muzitsulo za valve kapena kupuma pamapewa.M'mimba mwake wa gasket ayenera kukhala wamkulu kuposa dzenje lamkati la malo osindikizira, ndipo m'mimba mwake akunja ayenera kukhala ang'onoang'ono kusiyana ndi kunja kwa kunja kwa malo osindikizira, kuti atsimikizire kuti gasket imaphwanyidwa mofanana.
3. Chidutswa chimodzi chokha cha gasket chimaloledwa kuyika, ndipo sichiloledwa kukhazikitsa zidutswa ziwiri kapena zingapo pakati pa malo osindikizira kuti athetse kusowa kwa kusiyana pakati pa malo awiri osindikizira.
4. Gasket yozungulira iyenera kusindikizidwa kuti mphete zamkati ndi zakunja za gasket zigwirizane, ndipo nsonga ziwiri za gasket siziyenera kukhudzana ndi pansi pa groove.
5. Kuyika kwa mphete za O, kupatula kuti mphete ndi groove ziyenera kukwaniritsa zofunikira za mapangidwe, kuchuluka kwa kuponderezana kuyenera kukhala koyenera.The flatness wa zitsulo dzenje O-mphete zambiri 10% mpaka 40%.Kuponderezana kwa mapindikidwe a rabara O-rings ndi cylindrical.Kusindikiza kwa static kumtunda ndi 13% -20%;malo amodzi osindikizira ndi 15% -25%.Pakuthamanga kwambiri kwamkati, kuponderezana kumayenera kukhala kokulirapo mukamagwiritsa ntchito vacuum.Pansi pa malo owonetsetsa kuti asindikizidwe, kucheperachepera kwa kuchuluka kwa kuponderezana, kumakhala bwino, komwe kumatha kukulitsa moyo wa O-ring.
6. Vutoli liyenera kukhala lotseguka lisanayambe kuyika gasket pachivundikirocho, kuti lisakhudze kukhazikitsa ndi kuwononga valve.Mukatseka chivundikirocho, gwirizanitsani malowo, ndipo musagwirizane ndi gasket pokankhira kapena kukoka kuti musasunthike ndi kukwapula kwa gasket.Pokonza malo a chivundikirocho, muyenera kukweza chivundikirocho pang'onopang'ono, ndikuchigwirizanitsa mofatsa.
7. Kuyika kwa ma gaskets okhala ndi bolted kapena ulusi ayenera kukhala kuti ma gaskets ali pamalo opingasa (chivundikiro cha gasket cholumikizira ulusi sayenera kugwiritsa ntchito ma wrench a chitoliro ngati pali malo olowera).Kumangitsa wononga kuyenera kutengera njira yofananira, yosinthika, komanso yogwira ntchito, ndipo mabawuti azikhala omangika bwino, mwaukhondo komanso osamasuka.
8. Gasket isanayambe kuponderezedwa, kupanikizika, kutentha, katundu wa sing'anga, ndi mawonekedwe a gasket zinthu ziyenera kumveka bwino kuti adziwe mphamvu yowonjezereka.Mphamvu yolimbikitsira isanayambe iyenera kuchepetsedwa momwe zingathere pokhapokha ngati kuyesa kwapanikizi sikudumphira (mphamvu yowonjezereka isanakwane idzawononga mosavuta gasket ndikupangitsa gasket kutaya mphamvu).
9. Pambuyo pa kutsekedwa kwa gasket, ziyenera kutsimikiziridwa kuti pali kusiyana kwapachiyambi kwa chidutswa cholumikizira, kuti pakhale malo osungiratu pamene gasket ikutha.
10. Pogwira ntchito pa kutentha kwakukulu, ma bolts adzakhala ndi kutentha kwakukulu, kumasuka kwa nkhawa, ndi kuwonjezereka kwapang'onopang'ono, zomwe zimapangitsa kuti pakhale kutuluka kwa gasket ndipo kumafuna kutenthedwa kwa kutentha.M'malo mwake, pansi pa kutentha kochepa, ma bolts amachepa ndipo amafunika kumasulidwa kuzizira.Kulimbitsa kotentha ndi kukakamiza, kumasula kuzizira ndiko kuchepetsa kupanikizika, kulimbitsa kutentha ndi kumasula kuzizira kuyenera kuchitidwa mutasunga kutentha kwa maola 24.
11. Pamene gasket yamadzimadzi imagwiritsidwa ntchito posindikiza pamwamba, malo osindikizira ayenera kutsukidwa kapena kusamalidwa pamwamba.Malo osindikizira apansi ayenera kukhala osagwirizana pambuyo pogaya, ndipo zomatira ziyenera kugwiritsidwa ntchito mofanana (zomatira ziyenera kugwirizana ndi momwe ntchito zikuyendera), ndipo mpweya uyenera kuchotsedwa momwe zingathere.Zomatira zosanjikiza nthawi zambiri zimakhala 0.1 ~ 0.2mm.Ulusi wa screw ndi wofanana ndi malo osindikizira athyathyathya.Zonse zolumikizana ziyenera kuphimbidwa.Ikalowa mkati, iyenera kukhala yoyima kuti ithandizire kutulutsa mpweya.Guluu sayenera kuchulukirachulukira kuti asatayike ndikudetsa ma valve ena.
12. Mukamagwiritsa ntchito tepi ya filimu ya PTFE yosindikiza ulusi, poyambira filimuyo iyenera kutambasulidwa woonda ndikumata pamwamba pa ulusi;ndiye tepi owonjezera pa poyambira ayenera kuchotsedwa kuti filimu kumamatira ku ulusi mu mawonekedwe mphero.Kutengera ndi kusiyana kwa ulusi, nthawi zambiri amavulala 1 mpaka 3.Njira yokhotakhota iyenera kutsata njira yokhotakhota, ndipo mapeto ake ayenera kukhala ogwirizana ndi poyambira;pang'onopang'ono kukoka filimuyo mu mphero mawonekedwe, kuti makulidwe a filimuyo ndi wogawana bala.Musanalowe mkati, kanikizani filimuyo kumapeto kwa ulusi kuti filimuyo ilowe mu ulusi wamkati pamodzi ndi screw;kupukuta kuyenera kukhala pang'onopang'ono ndipo mphamvu iyenera kukhala yofanana;musasunthenso mutatha kulimbitsa, ndipo pewani kutembenuka, mwinamwake kudzakhala kosavuta kutulutsa.
