Njira zingapo zolumikizira zodziwika bwino za mavavu azitsulo zosapanga dzimbiri
2024-01-03 09:35:26
Ma valve zitsulo zosapanga dzimbiri amagwiritsidwa ntchito kwambiri m'mafakitale. Pali mitundu yambiri ndi njira zolumikizirana. Momwe valavu yonse yachitsulo chosapanga dzimbiri imalumikizidwa ndi payipi kapena zida sizinganyalanyazidwe. Mavavu achitsulo chosapanga dzimbiri amawoneka kuti ali ndi madzi akuthamanga, akutuluka, akudontha, ndi kutsika. Ambiri aiwo ndi chifukwa njira yolumikizira yolondola sinasankhidwe.Zotsatirazi zikuwonetsa njira zolumikizira ma valve zachitsulo chosapanga dzimbiri.
1. Kulumikizana kwa Flange
Kulumikizana kwa flange ndi njira yolumikizira yomwe imagwiritsidwa ntchito kwambiri pakati pa ma valve osapanga dzimbiri ndi mapaipi kapena zida. Zimatanthawuza kugwirizanitsa komwe kungawonongeke komwe ma flanges, ma gaskets ndi ma bolts amagwirizanitsidwa wina ndi mzake monga gulu lazinthu zosindikizira pamodzi. Chitoliro cha chitoliro chimatanthawuza kuphulika kwa mapaipi omwe amagwiritsidwa ntchito popanga mapaipi, ndipo akagwiritsidwa ntchito pazida, amatanthauza kulowera ndi kutulutsa kwa zida. Malumikizidwe a Flange ndi osavuta kugwiritsa ntchito ndipo amatha kupirira kukakamizidwa kwambiri. Kulumikizana kwa flange kungagwiritsidwe ntchito pazitsulo zosapanga dzimbiri zosapanga dzimbiri zamitundu yosiyanasiyana komanso kukakamiza mwadzina, koma pali zoletsa zina pa kutentha kwa ntchito. Pansi pa kutentha kwambiri, ma flange olumikiza mabawuti amatha kukwawa ndikuyambitsa kutayikira. Nthawi zonse, kulumikizana kwa Flange kumalimbikitsidwa kuti agwiritsidwe ntchito pa kutentha kwa ≤350 ° C.
2. Kulumikizana kwa ulusi
Iyi ndi njira yosavuta yolumikizira yomwe imagwiritsidwa ntchito pazitsulo zazing'ono zosapanga dzimbiri.
1) Kusindikiza mwachindunji: Ulusi wamkati ndi wakunja umakhala ngati zisindikizo. Pofuna kuonetsetsa kuti kugwirizana sikukutha, mafuta otsogolera, nsalu ndi tepi yakuda amagwiritsidwa ntchito nthawi zambiri kudzaza.
2) Kusindikiza kwachindunji: Mphamvu yomangirira ulusi imatumizidwa ku ma gaskets pa ndege ziwiri, kulola ma gaskets kukhala ngati zisindikizo.
3. Kuwotcherera kugwirizana
Kulumikizana kowotcherera kumatanthawuza mtundu wa kulumikizana komwe valavu yachitsulo chosapanga dzimbiri imakhala ndi poyambira ndipo imalumikizidwa ndi mapaipi kudzera pakuwotcherera. Kulumikizana kowotcherera pakati pa mavavu osapanga dzimbiri ndi mapaipi amatha kugawidwa kukhala kuwotcherera matako (BW) ndi kuwotcherera zitsulo (SW). Malumikizidwe osapanga dzimbiri valavu matako kuwotcherera (BW) angagwiritsidwe ntchito makulidwe osiyanasiyana, kupsyinjika ndi chilengedwe kutentha; pomwe zolumikizira zowotcherera zitsulo (SW) nthawi zambiri zimakhala zoyenera mavavu osapanga dzimbiri ≤DN50.
4. Kulumikizana kwa manja a khadi
Mfundo yogwiritsira ntchito kugwirizana kwa ferrule ndi yakuti pamene nati imangirizidwa, ferrule imakhala yopanikizika, zomwe zimapangitsa kuti tsamba lake lilume mu khoma lakunja la chitoliro. Mbali yakunja ya chulucho ya ferrule imalumikizana kwambiri ndi cone pamwamba pa olowa pansi pa kukakamizidwa, motero kupewa kutayikira modalirika. .Ubwino wa fomu yolumikizira iyi ndi:
1) Kukula kwakung'ono, kulemera kopepuka, kapangidwe kosavuta, kosavuta kusokoneza ndikusonkhanitsa;
2) Mphamvu yolumikizira yolimba, yogwiritsidwa ntchito mosiyanasiyana, ndipo imatha kupirira kuthamanga kwambiri (1000 kg/cm²), kutentha kwakukulu (650 ℃) ndi kugwedezeka kwamphamvu;
3) Zida zosiyanasiyana zimatha kusankhidwa, zoyenera zotsutsana ndi dzimbiri;
4) Zofunikira pakuwongolera bwino sizokwera;
5) Easy kukhazikitsa pa okwera.
Pakalipano, fomu yolumikizira ferrule yatengedwa muzinthu zina zazing'ono zazitsulo zosapanga dzimbiri m'dziko langa.
Imeneyi ndi njira yofulumira yolumikizira yomwe imafuna ma bolts awiri okha ndipo ndi yoyenera kwa ma valve otsika otsika osapanga dzimbiri omwe nthawi zambiri amaphwanyidwa.
Kulumikizana kodzilimbitsa mkati ndi mtundu wa kulumikizana komwe kumagwiritsa ntchito kukakamiza kwapakatikati pakudzilimbitsa. Kuchuluka kwa mphamvu yapakati, mphamvu yodzilimbitsa yokha imakhala yaikulu. Choncho, mawonekedwe ogwirizanitsa awa ndi oyenera ma valves azitsulo zosapanga dzimbiri. Poyerekeza ndi kugwirizana kwa flange, imapulumutsa zinthu zambiri ndi anthu ogwira ntchito, koma imafunanso mphamvu inayake yotsegulira kuti igwiritsidwe ntchito modalirika pamene kupanikizika kwa valve sikuli kwakukulu. Mavavu achitsulo osapangapanga opangidwa ndi mfundo zodzilimbitsa okha nthawi zambiri amakhala ma valve achitsulo osapanga dzimbiri.
Palinso mitundu ina yambiri yolumikizira mavavu achitsulo chosapanga dzimbiri. Mwachitsanzo, mavavu ena ang’onoang’ono achitsulo osapanga dzimbiri omwe safunikira kung’ambika amawotchedwa ndi mapaipi; mavavu ena osapanga zitsulo zosapanga dzimbiri amagwiritsa ntchito ma socket, etc. Ogwiritsa ntchito zitsulo zosapanga dzimbiri ayenera kuwachitira mwachindunji malinga ndi momwe zinthu zilili.
