Mfundo Zosankhidwa
(1) chitetezo ndi kudalirika. Perutrochemical, magetsi, ma metaldurgy ndi mafakitale ena opanga mayendedwe opitilira, okhazikika, okhazikika. Chifukwa chake, valavu yofunikira iyenera kukhala yodalirika kwambiri, chinthu chachikulu chotetezedwa, sichingapangitse ovulala kwambiri chifukwa cha kulephera kwamphamvu, kuti akwaniritse zofunikira za chipangizocho. Kuphatikiza apo, kuchepetsa kapena kupewa kutaya kutaya kwa mavumbo, pangani fakitale yoyera, yotukuka, kukhazikitsidwa kwa thanzi, chitetezo, kayendetsedwe ka chitetezero.
(2) Pangani zofunika popanga njirayi. Valavuyo iyenera kukwaniritsa zofunikira zogwiritsira ntchito sing'anga, kuthamanga kwa ntchito, kutentha kwantchito ndi kugwiritsa ntchito, komwe kumakhalanso kofunikira kwa ma valavu. Ngati valavu ikuyenera kuteteza kuwonongeka ndikutulutsa sing'anga kwambiri, chitetezo cha chitetezo cha chitetezo chambiri chidzasankhidwe; Pofuna kuletsa valavu yobwezeretsanso nthawi ya opaleshoni, khalaniChongani valavu; Ingochotsani madzi, mpweya ndi mpweya wina wosaphika womwe umapangidwa mu pipi ndi zida, pomwe kuletsa kuthwa, kukhetsa valavu yamphamvu. Kuphatikiza apo, sing'anga ndi yowononga, zinthu zabwino zotsutsana ndi zotsutsana ziyenera kusankhidwa.
(3) Ntchito yabwino, kukhazikitsa ndi kukonza. Valavu ikaikidwa, wothandizirayo amayenera kudziwa bwino ma Val Varm, kutsegula chizindikiro ndi chizindikiro cha chisonyezo, kuti muthane ndi zolakwika zosiyanasiyana zosiyanasiyana. Nthawi yomweyo, mtundu wosankhidwa wa Valve uyenera kukhala momwe angathere, kuyika kosavuta ndi kukonza.
(4) Chuma. Pansi pa chidindo choyenera kugwiritsa ntchito njira zogwiritsira ntchito ma pipelines, mitengo yotsika mtengo yopanga ndi mawonekedwe osavuta kuti muchepetse ndalamazo, pewani kuyika kwa valavu ya valavu ndikukonzanso pambuyo pake.
Makina Osankha Masitepe
1.Dentermine ntchito ya valavu malinga ndi kugwiritsa ntchito valavu mu chipangizocho kapena kayendedwe katatu. Mwachitsanzo, kugwirira ntchito sing'anga kwapakatikati, kulimbikira komanso kutentha kwa ntchito, etc.
2.Nentum
3.Ndiponseponse mu Valve Mitundu ya Varve ndi Magalimoto molingana ndi cholinga cha valavu. Mitundu mongavala ngalande yagolide, Chongani valavu, valavu ya pachipata,valavu, etc.oyendetsa monga momwe nyongolotsi gudumu mafuta, yamagetsi, chibayo, etc.
4.Kodi kutsamba mwadzina wa valavu. Kupanikizika kwa nomwenal ndi kukula kwa valavu kudzakhala kofanana ndi chitoliro chomwe chingakhazikike. Mavavu ena amasankha kukula kwa valavu ya valavu malinga ndi kuchuluka kwa nkhuni kapena kutulutsa kwa valavu panthawi yovotayo.
5.Kula Monga flange, kuwotcherera, clip kapena ulusi, etc.
6.Nentery Monga chipata chakuda cha rod, angle flobe valavu, valavu ya mpira, etc.
Malinga ndi mawonekedwe a sing'anga, kukakamizidwa ndi kutentha komanso kutentha koyenera, ku kusankha koyenera kwa chipolopolo cha valavu ya valavu komanso zida zamkati.
