Kukhazikitsa ma valve a mpira olumikizidwa mokwanira
(1) Kukweza. Vavu iyenera kukwezedwa m'njira yoyenera. Kuti muteteze tsinde la valavu, musamange unyolo wokweza ku gudumu lamanja, bokosi la gear kapena actuator. Musachotse zipewa zoteteza kumapeto onse a valavu musanaziwotchere.
(2) Kuwotcherera. Kulumikizana ndi payipi yayikulu kumawotcherera. Ubwino wa msoko wowotcherera uyenera kukwaniritsa muyezo wa "Radiography of Welded Joints of Disk Flexion Fusion Welding" (GB3323-2005) Giredi II. Nthawi zambiri, kuwotcherera kamodzi sikungatsimikizire ziyeneretso zonse. Chifukwa chake, poyitanitsa valavu, wopanga ayenera kupempha wopanga kuti awonjezere 1.0m kumapeto onse a valavu. Chitoliro cha sleeve, msoko wowotcherera ukapanda kuyeneretsedwa, pamakhala kutalika kokwanira kudula msoko wowotcherera wosayenerera ndikuwotchereranso. Vavu ya mpira ndi payipi zikawotcherera, valavu iyenera kukhala pamalo otseguka 100% kuti valavu ya mpira isawonongeke ndi slag yowotcherera, ndipo nthawi yomweyo onetsetsani kuti valavuyo kutentha kwa chisindikizo chamkati sikupitirira madigiri 140 Celsius, ndipo njira zoyenera zoziziritsira zitha kuchitidwa ngati pakufunika.
(3) Kumanga chitsime cha valavu. Chimagwiritsa ntchito kapangidwe kake kapadera ndipo chili ndi makhalidwe osakonza. Musanakwirire, ikani chophimba chapadera cha Pu chotsutsana ndi dzimbiri kunja kwa valavu. Tsinde la valavu limatambasulidwa moyenera malinga ndi kuya kwa nthaka, kuti antchito athe kumaliza ntchito zosiyanasiyana pansi. Pambuyo poti kuyika mwachindunji, ndikokwanira kumanga chitsime chaching'ono cha valavu. Pa njira zachikhalidwe, sichingakwiridwe mwachindunji, ndipo zitsime zazikulu za valavu ziyenera kumangidwa, zomwe zimapangitsa kuti malo otsekedwa akhale owopsa, omwe sangagwire ntchito bwino. Nthawi yomweyo, thupi la valavu lokha ndi zigawo zolumikizira bolt pakati pa thupi la valavu ndi payipi zidzakwiriridwa, zomwe zidzakhudza moyo wa ntchito ya valavu.
Kodi ndi chiyani chomwe chiyenera kuganiziridwa pokonza valavu ya mpira yolumikizidwa mokwanira?
Mfundo ndi yakuti ngati yatsekedwa, madzi opanikizika amakhalabe mkati mwa thupi la valavu.
Mfundo yachiwiri ndi yakuti musanakonze, choyamba tulutsani mphamvu ya payipi kenako sungani valavu pamalo otseguka, kenako dulani mphamvu kapena gwero la gasi, kenako chotsani actuator kuchokera pa bulaketi, ndipo pokhapokha zonse zomwe zili pamwambapa zitakonzedwa.
Mfundo yachitatu ndikupeza kuti kupanikizika kwa mapaipi akumtunda ndi akumunsi kwa valavu ya mpira kwachepa kwambiri, kenako kusweka ndi kuwonongeka kumatha kuchitika.
Mfundo zinayizi ziyenera kusamala kwambiri pakuchotsa ndi kuyikanso zinthu, kuti zisawononge pamwamba pa zitseko, kugwiritsa ntchito zida zapadera kuchotsa mphete ya O, ndikulimbitsa mabotolo pa flange mofanana komanso pang'onopang'ono komanso mofanana panthawi yopangira.
Mfundo zisanu: Poyeretsa, chotsukira chomwe chimagwiritsidwa ntchito chiyenera kugwirizana ndi zida za rabara, zida zapulasitiki, zida zachitsulo ndi chida chogwirira ntchito mu valavu ya mpira. Ngati chida chogwirira ntchito ndi gasi, mafuta angagwiritsidwe ntchito kuyeretsa zida zachitsulo, ndipo Pa zida zosakhala zachitsulo, muyenera kugwiritsa ntchito madzi oyera kapena mowa kuti muyeretse. Zigawo zowola zimatsukidwa pozitsuka m'madzi, ndipo zigawo zachitsulo za zida zosakhala zachitsulo zomwe sizinawole zimatsukidwa ndi nsalu yoyera komanso yosalala ya silika yoviikidwa mu chotsukira, ndipo mafuta onse omatirira pamwamba pa khoma ayenera kuchotsedwa. , dothi ndi fumbi. Komanso, sizingasonkhanitsidwe nthawi yomweyo mutatsuka, ndipo zitha kuchitika kokha chida chotsukira chitatha kuuma.
