Mavavu nthawi zambiri amalumikizidwa ndi mapaipi m'njira zosiyanasiyana monga ulusi, ma flanges, kuwotcherera, ma clamp, ndi ma ferrules.Kotero, posankha ntchito, momwe mungasankhire?
Kodi njira zolumikizirana ndi mavavu ndi mapaipi ndi ziti?
1. Kulumikizana kwa ulusi: Kulumikizana kwa ulusi ndi mawonekedwe omwe mbali ziwiri za valve zimasinthidwa kukhala ulusi wamkati kapena ulusi wakunja kuti ugwirizane ndi payipi.Nthawi zambiri, mavavu a mpira pansi pa mainchesi 4 ndi mavavu a globe, ma valve olowera pachipata ndi ma cheke omwe ali pansi pa mainchesi awiri amakhala olumikizidwa kwambiri.Mapangidwe olumikizira ulusi ndi osavuta, kulemera kwake ndi kopepuka, ndipo kuyika ndi kuphatikizira ndikosavuta kukonza ndikusintha.Popeza valavu idzakula mothandizidwa ndi kutentha kwapakati ndi kutentha kwapakati panthawi yogwiritsira ntchito, kuonetsetsa kuti ntchito yabwino yosindikizira ikugwira ntchito, ma coefficients owonjezera a zipangizo ziwiri pamapeto ogwirizanitsa ayenera kuganiziridwa bwino.Pakhoza kukhala njira zazikulu zotayikira pamalumikizidwe olumikizidwa, kotero zosindikizira, matepi osindikiza kapena zodzaza zitha kugwiritsidwa ntchito kutsekereza mayendedwe awa kuti muwonjezere kusindikiza.Ngati ndondomekoyi ndi zinthu za thupi la valve zikhoza kuwotcherera, zikhoza kusindikizidwa pambuyo pa kugwirizana kwa ulusi.Kugonana kungakhale bwino.
2. Kulumikizana kwa Flange: Kulumikizana kwa Flange ndi njira yolumikizirana kwambiri mu ma valve.Kuyika ndi disassembly ndizosavuta kwambiri, ndipo kugwirizana kwa flange ndi kodalirika mu kusindikiza, komwe kumakhala kofala kwambiri muzitsulo zothamanga kwambiri komanso zazikulu.Komabe, mapeto a flange ndi olemetsa, ndipo mtengo wake ndi wokwera kwambiri.Komanso, kutentha kupitirira 350 ℃, chifukwa cha kupumula kwa ma bolts, ma gaskets ndi flanges, katundu wa bolts adzachepetsedwa kwambiri, ndipo kugwirizana kwa flange ndi kupsinjika kwakukulu kumatha kutayikira, komwe sikuli koyenera kugwiritsidwa ntchito.
3. Malumikizidwe opangidwa ndi welded Malumikizidwe owotcherera nthawi zambiri amakhala ndi mitundu iwiri ya mapangidwe: kuwotcherera zitsulo ndi matako.Nthawi zambiri, kuwotcherera kwa socket kumagwiritsidwa ntchito ngati ma valve otsika.Kapangidwe kawotcherera ka ma socket welding ma valve ndi osavuta kukonza komanso osavuta kukhazikitsa.Kuwotchera kwa matako kumagwiritsidwa ntchito pa valavu yothamanga kwambiri kumakhala ndi mtengo wokwera, ndipo kuwotcherera kumafunika kupangidwa molingana ndi muyeso wa mapaipi, omwe ndi ovuta kukonza, komanso kuwotcherera ndi kuyikanso kumakhala kovuta kwambiri.Munjira zina, kuyesa kwa radiographic kosawononga kumafunikanso pakuwotcherera kugwirizana.Pamene kutentha kupitirira 350 ° C, katundu wa ma bolts adzachepetsedwa kwambiri chifukwa cha kupumula kwa ma bolts, ma gaskets ndi flanges, ndipo kutayikira kungathe kuchitika mu kugwirizana kwa flange ndi kupsinjika kwakukulu.
4. Kulumikizana kwa Clamp Kulumikizana kwa Clamp kuli ngati flange, koma mawonekedwe ake ndi opepuka komanso otsika mtengo amagwiritsidwa ntchito popanga mapaipi ndi zida zaukhondo.Mapaipi aukhondo amayenera kutsukidwa, ndipo ndizoletsedwa kukhala ndi zotsalira kuti apange mabakiteriya, kotero kulumikizana kwa flange ndi ulusi wa ulusi sikoyenera, ndipo kulumikizana ndi kuwotcherera kumakhala kovuta kukhazikitsa ndi kugawa.Chifukwa chake, kulumikizana kwa clamp ndikofala kwambiri pamapaipi aiwisi.njira yolumikizirana.
