4. Tsinde la valve lowonongeka liyenera kusinthidwa mwamsanga pambuyo popindika ndikutha;iyenera kuwongoledwa ndi kukonzedwa.

5. Gland iyenera kukhala ndi kusiyana kolimba koyambirira kopitilira 5mm, kulongedzako kumayenera kuyikidwa pogwiritsa ntchito nambala yokhotakhota, ndipo gland iyenera kumangika molingana ndi symmetrically.

6. Maboliti owonongeka, zotupa, ndi ziwalo zina ziyenera kukonzedwa kapena kusinthidwa nthawi yomweyo;

7. Malangizo ogwiritsira ntchito ayenera kutsatiridwa, ndi gudumu lamanja lomwe limagwira ntchito mwamphamvu wamba komanso liwiro lokhazikika;

8. Mangitsani ma bolt a gland mofanana komanso mofanana.Malo pakati pa chithokomiro ndi tsinde la valavu ayenera kukulitsidwa moyenerera ngati ali ochepa kwambiri, kapena ayenera kusinthidwa ngati ndi aakulu kwambiri.

3. Malo osindikizira akutuluka

chifukwa:

1. Malo osindikizira sangathe kupanga mzere wapafupi ndipo siwophwanyidwa;

2. Chipinda chapamwamba cha membala wolumikizana ndi tsinde mpaka kutseka sichimalunjika bwino, chawonongeka, kapena chikulendewera;

3. Zigawo zotsekera zimakhala zopotoka kapena kuchoka pakati chifukwa cha tsinde la valve kukhala lopunduka kapena lopangidwa molakwika;

4. Valve sichimasankhidwa molingana ndi momwe ntchito ikugwirira ntchito kapena kusindikiza pamwamba pa khalidwe lapamwamba silinasankhidwe molondola.

1. Sankhani bwino mtundu wa gasket ndi zinthu malinga ndi malo ogwirira ntchito;

2. Kukhazikitsa mosamala ndikuwongolera magwiridwe antchito;

3. Mabotiwo ayenera kukhala ofanana komanso olimba.Wrench ya torque iyenera kugwiritsidwa ntchito ngati ikufunika.Mphamvu yomangirira isanachitike iyenera kukhala yokwanira osati yokwera kwambiri kapena yotsika kwambiri.Pakati pa flange ndi kugwirizana kwa ulusi, payenera kukhala kusiyana koyambirira;

4. Mphamvu iyenera kukhala yofanana ndipo msonkhano wa gasket uyenera kukhala pakati.Ndizoletsedwa kugwiritsa ntchito ma gaskets awiri ndi kuphatikizira ma gaskets;

5. Malo osindikizira osasunthika asinthidwa ndipo amawonongeka, owonongeka, komanso otsika kwambiri.Kuonetsetsa kuti malo osindikizira osasunthika akukwaniritsa zofunikira, kukonzanso, kugaya, ndi kuyesa mitundu kuyenera kupangidwa;

6. Samalani ndi ukhondo polowetsa gasket.Palafini ayenera kugwiritsidwa ntchito kuyeretsa pamalo osindikizira, ndipo gasket sayenera kugwa pansi.
