Kodi njira zolumikizira agulugufe ku payipi ndi ziti?

Kaya kusankha njira yolumikizirana pakati pa valavu ya gulugufe ndi payipi kapena zida ndi zolondola kapena ayi kungakhudze mwachindunji kuthekera kwa kuthamanga, kudontha, kudontha ndi kutsika kwa valavu ya mapaipi.Njira zodziwika bwino zolumikizira ma valve ndi: kulumikizana kwa flange, kulumikizana kwa wafer, kulumikiza kwa matako, kulumikizana kwa ulusi, kulumikizana kwa ferrule, kulumikizana kwa clamp, kulumikizana kodzisindikizira ndi mitundu ina yolumikizira.

A. Kulumikizana kwa Flange
Kulumikizana kwa Flange ndi avalavu ya butterflyndi ma flanges pa malekezero onse a valavu thupi, amene amafanana ndi flanges pa payipi, ndipo anaika mu payipi ndi bolting ndi flanges.Kulumikizana kwa Flange ndiye njira yolumikizira yomwe imagwiritsidwa ntchito kwambiri pamavavu.Flanges amagawidwa kukhala otukukira pansi (RF), flat surface (FF), convex ndi concave pamwamba (MF), etc.

B. Kulumikizana kwa Wafer
Vavu waikidwa pakati flanges awiri, ndi valavu thupi lavalavu ya butterflynthawi zambiri imakhala ndi dzenje loyika kuti lithandizire kuyika ndi kuyika.

C. Kulumikizana kwa Solder
(1) Kuwotcherera matako: Malekezero onse a thupi la vavu amakonzedwa kuti akhale zitsulo zowotcherera matako malinga ndi zofunikira zowotcherera matako, zomwe zimagwirizana ndi zitsulo zowotcherera za payipi, ndipo zimakhazikika papaipi ndi kuwotcherera.
(2) Socket kuwotcherera kugwirizana: Malekezero onse a valavu thupi kukonzedwa malinga ndi zofunika kuwotcherera zitsulo, ndipo olumikizidwa ndi payipi ndi kuwotcherera zitsulo.

D. Kulumikizana kwa ulusi
Kulumikizana kwa ulusi ndi njira yosavuta yolumikizira ndipo nthawi zambiri imagwiritsidwa ntchito pama valve ang'onoang'ono.Thupi la valve limakonzedwa molingana ndi ulusi uliwonse, ndipo pali mitundu iwiri ya ulusi wamkati ndi ulusi wakunja.Imafanana ndi ulusi pa chitoliro.Pali mitundu iwiri yolumikizirana ulusi:
(1) Kusindikiza mwachindunji: Ulusi wamkati ndi wakunja mwachindunji umagwira ntchito yosindikiza.Pofuna kuonetsetsa kuti kugwirizana sikukutha, nthawi zambiri kumadzazidwa ndi mafuta otsogolera, hemp ya ulusi ndi tepi ya PTFE yaiwisi;mwa omwe PTFE zopangira tepi chimagwiritsidwa ntchito;nkhaniyi ili ndi kukana kwa dzimbiri komanso kusindikiza kwabwino kwambiri.Ndi yosavuta kugwiritsa ntchito ndi kusunga.Posokoneza, imatha kuchotsedwa kwathunthu chifukwa ndi filimu yosakanizika, yomwe ili yabwino kwambiri kuposa mafuta otsogolera ndi hemp ya ulusi.
(2) Kusindikiza kwachindunji: mphamvu yomangirira ulusi imaperekedwa ku gasket pakati pa ndege ziwirizi, kotero kuti gasket imagwira ntchito yosindikiza.

E. kugwirizana ferrule
Kulumikizana kwa ferrule kudapangidwa mdziko langa zaka zaposachedwa.Kulumikizana kwake ndi mfundo yosindikizira ndikuti pamene mtedza umamitsidwa, ferrule imapanikizika, kotero kuti m'mphepete mwa ferrule mumaluma kunja kwa khoma la chitoliro, ndipo chigawo chakunja cha ferrule chimagwirizanitsidwa ndi olowa pansi. kupanikizika.Mkati mwa thupi ndi pafupi kwambiri ndi tapered pamwamba, kotero kutayikira akhoza kupewedwa modalirika.Monga ma valve a zida.Ubwino wa njira yolumikizira iyi ndi:
(1) Kukula kwakung'ono, kulemera kopepuka, kapangidwe kosavuta, kusokoneza kosavuta ndi msonkhano;
(2) Mphamvu yolumikizana yolimba, yogwiritsidwa ntchito mosiyanasiyana, kukana kuthamanga kwambiri (1000 kg/cm 2), kutentha kwakukulu (650 ° C) ndi kugwedezeka ndi kugwedezeka;
(3) Zida zosiyanasiyana zimatha kusankhidwa, zoyenera zotsutsana ndi dzimbiri;
(4) Zofunikira pakulondola kwa makina sizokwera;
(5) Ndi yabwino kukhazikitsa okwera.
Pakalipano, mawonekedwe a ferrule kugwirizana atengedwa muzinthu zina zazing'ono za valve m'dziko langa.

F. Kulumikizana kokulirapo
Iyi ndi njira yolumikizira mwachangu, imangofunika mabawuti awiri, ndivalavu ya butterfly yakumapetondi oyenera kutsika kwapansivalavu butterflyzomwe nthawi zambiri zimaphwanyidwa.monga mavavu aukhondo.

G. Kulumikizana kodzilimbitsa kwamkati
Mafomu onse omwe ali pamwambawa amagwiritsira ntchito mphamvu yakunja kuti athetse kupanikizika kwapakati kuti akwaniritse kusindikiza.Zotsatirazi zikufotokoza kudziletsa kumangitsa kugwirizana mawonekedwe ntchito sing'anga kuthamanga.
Mphete yake yosindikizira imayikidwa pa cone yamkati ndipo imapanga ngodya inayake ndi mbali yoyang'ana pakati.Kupanikizika kwa sing'anga kumaperekedwa ku cone yamkati ndiyeno ku mphete yosindikiza.Pa cone pamwamba pa ngodya inayake, mphamvu ziwiri zimapangidwira, imodzi ndi Mzere wapakati wa thupi la valve ndi wofanana ndi kunja, ndipo winayo amapanikizidwa ndi khoma lamkati la thupi la valve.Mphamvu yotsiriza ndiyo kudzilimbitsa yokha.Kuchuluka kwa mphamvu yapakati, mphamvu yodzilimbitsa yokha imakhala yaikulu.Choncho, mawonekedwe ogwirizanitsa awa ndi oyenera ma valve othamanga kwambiri.
Poyerekeza ndi kugwirizana kwa flange, zimapulumutsa zinthu zambiri ndi anthu ogwira ntchito, koma zimafunanso kuyikapo kale, kuti zigwiritsidwe ntchito modalirika pamene kupanikizika kwa valve sikuli kwakukulu.Mavavu opangidwa pogwiritsa ntchito mfundo yodzilimbitsa okha nthawi zambiri amakhala ma valve opanikizika kwambiri.

Pali mitundu yambiri yolumikizira ma valve, mwachitsanzo, ma valve ena ang'onoang'ono omwe safunikira kuchotsedwa amawotchedwa ndi mapaipi;ma valve ena opanda zitsulo amalumikizidwa ndi sockets ndi zina zotero.Ogwiritsa ntchito ma valve ayenera kuthandizidwa malinga ndi momwe zinthu zilili.

Zindikirani:
(1) Njira zonse zolumikizira ziyenera kutchula miyeso yofananira ndikufotokozeranso miyeso yoletsa valavu yosankhidwa kuti isayikidwe.
(2) Nthawi zambiri, payipi ya m'mimba mwake ndi valavu zimagwirizanitsidwa ndi flange, ndipo payipi yaing'ono ndi valavu zimagwirizanitsidwa ndi ulusi.
