Njira yosungiramo ma valve:

Odzaza pulojekitiyi makamaka amakhala ndi zinthu ziwiri zotsatirazi: PTFE ndi graphite yofewa.

Akasungidwa, amasindikizidwa mu thumba kapena bokosi. Sungani bwino mu nkhokwe youma ndi mpweya wabwino, pewani kuwala kwa dzuwa. Samalani ndi mpweya wabwino panthawi yosungirako nthawi yayitali, ndipo sungani kutentha kwa malo osungirako kusapitirire 50 ° C kuti muteteze fumbi lambiri. Ngati fumbi lomwe lili pamwamba pa chodzaza lichotsedwa ndikugwiritsidwa ntchito, pukutani ndi nsalu yoyera.

Njira yosinthira ma valve:

Zisindikizo zolongedza zidapangidwa motere: 1). Kupakira nati woponderezedwa, 2) Bolt, 3) Pini yokhazikika, 4) Kuyika, 5) Kuyika manja, 6) Kuyika mbale zopondereza (nthawi zina 5 ndi 6 ndi magawo ofunikira malinga ndi nkhungu ndi Kutsimikiziridwa ndi magwiridwe antchito osiyanasiyana, ntchito yonseyo ndizofanana ndi zomwe zagawanika)

Njira zosinthira seal packing ndi izi:

1. Gwiritsani ntchito wrench kuti muchotse 1) mtedza woponderezedwa wolongedza ndikuwukweza 5) chikhomo chosindikizira ndi 6) mbale yosindikizira, kusiya mpata woti mulowe m'malo mwake.

2. Gwiritsani ntchito screwdriver yathyathyathya kapena zidutswa zina zachitsulo kuchotsa zolongedza zoyambira ndikuyika zina zatsopano. Ngati kulongedza katundu kukugwiritsidwa ntchito, poyikiranso kulongedza kwatsopano, samalani kuti mayendedwe odulidwawo agwedezeke ndi 90 ~ 180 °, ndipo mbali yophatikizidwayo iyenera kubwerezedwa awiriawiri. Musakhale ndi kuphatikizika kangapo mbali imodzi monga momwe zasonyezedwera pachithunzichi;

3. Mutatha kuyika kuchuluka koyenera kwa kulongedza, bwezeretsani 5) kunyamula gland ndi 6) kuyika mbale zokakamiza. Mukayika, tcherani khutu ku malo a chisindikizo chonyamulira ndi 6 ~ 10mm mkati mwa chivundikiro cha valve (kapena 1.5 ~ 2 nthawi ya makulidwe onyamula) monga malo owonetsera (Monga momwe tawonetsera pansipa).

4. Bwezerani 1). Kuyika mtedza woponderezedwa, 2) Limbikitsani malo oyika bawuti olowa mpaka ifike 20% ya kupanikizana kolongedza.

5. Mukamaliza masitepe omwe ali pamwambawa, chitani zowunikira zazikulu pa valve yomwe yalowa m'malo mwa kulongedza muzotsatira zomwe zikugwiritsidwa ntchito kuti muwone ngati kuli kofunikira kuonjezera kunyamula kwapang'onopang'ono.

Ndemanga: Malangizo olimbikitsanso ndikuwongolera kulongedza pansi pamavuto.

Ntchito zotsatirazi ndizowopsa. Chonde musawayese mopepuka ngati sakufunika. Chonde tsatirani mosamalitsa chikalata ichi mukamagwira ntchito:

1. Wogwiritsa ntchitoyo ayenera kudziwa bwino makina ndi ma valve. Kuphatikiza pa zida zamakina zofunika, wogwiritsa ntchito ayenera kuvala magolovesi oteteza kutentha, zishango zakumaso, ndi zipewa.

2. Valavu imatsegulidwa kwathunthu mpaka chisindikizo chapamwamba cha valve chikugwira ntchito bwino. Maziko a chiweruzo ndi chakuti makina opangira ma valve sangathenso kukweza tsinde la valve, ndipo palibe phokoso lachilendo pa tsinde la valve.

3. Wogwiritsa ntchitoyo ayenera kukhala kumbali ya malo osindikizira kapena malo ena omwe sangathe kuwonetsedwa. Ndizoletsedwa kuyang'anizana ndi malo onyamula. Pamene kulongedza kukufunika kumangirizidwa, gwiritsani ntchito wrench kuti mumize 1) Kuyika mtedza wa compression, 2 ~ 4 mano, mbali zonse za nati yopakira kupakira Iyenera kuphedwa, osati mbali imodzi.

4. Pamene kulongedza kukufunika kusinthidwa, gwiritsani ntchito wrench kuti mutulutse 1) Kuyika mtedza wa compression, 2 ~ 4 mano, mtedza wopondereza wonyamula mbali zonse ziwiri uyenera kuphedwa mosinthana. Panthawiyi, ngati pali kuyankha kwachilendo kuchokera ku tsinde la valve, nthawi yomweyo imani ndi kubwezeretsanso mtedzawo, pitirizani Gwiritsani ntchito njira yogwiritsira ntchito valavu motsatira ndondomekoyi mu sitepe 2, malizitsani chisindikizo pa tsinde la valve mpaka chikugwira ntchito bwino, ndi kupitiriza m'malo kulongedza. Kulongedza m'malo mopanikizika sikuloledwa kusinthidwa kwathunthu kupatula zochitika zapadera. Kuchuluka kolowa m'malo ndi 1/3 ya zonyamula zonse. Ngati sikungatheke kuweruza, mapaketi atatu apamwamba amatha kusinthidwa. Kuyikako kukatha, bwezeretsaninso kuyika kwa 5 packing press sleeve ndi 6 packing press plate. Mukayika, tcherani khutu ku malo a chisindikizo chonyamulira ndi 6 ~ 10mm mkati mwa chivundikiro cha valve (kapena 1.5 ~ 2 nthawi ya makulidwe a kulongedza) monga malo owonetsera. Bwezerani 1). Kunyamula mtedza woponderezedwa, 2) Limbikitsani malo oyika bawuti yolumikizirana mpaka 25% yakupanikizana kwakukulu kwapake. Ngati palibe kutayikira pansi valavu tsinde kulongedza katundu, ndi wathunthu. Ngati pali kutayikira, tsatirani njira zomwe zili mugawo 2 ndi 3 kuti mukhwime.

5. Masitepe onse omwe ali pamwambawa ndi okhawo okwera ma valve okweza tsinde monga: valavu yachipata cha tsinde, valavu yoyimitsa tsinde, ndi zina zotero, osagwira ntchito ku tsinde lakuda ndi mavavu a tsinde osakweza monga: valavu yachipata chakuda, valavu yakuda. valavu yoyimitsa tsinde, valavu ya butterfly, ma valve a Mpira ndi zina zotero.
