Kaya kusankha njira yolumikizira pakati pa valavu ya gulugufe ndi payipi kapena zida zake kuli kolondola kapena ayi kudzakhudza mwachindunji kuthekera kwa valavu ya payipi kuyenda, kudontha, kudontha ndi kutuluka. Njira zodziwika bwino zolumikizira valavu ndi izi: kulumikizana kwa flange, kulumikizana kwa wafer, kulumikizana kwa welding ya matako, kulumikizana kwa ulusi, kulumikizana kwa ferrule, kulumikizana kwa clamp, kulumikizana kodzitsekera ndi mitundu ina yolumikizira.
A. Kulumikizana kwa Flange
Kulumikizana kwa Flange ndivalavu ya gulugufe yozungulirandi ma flanges kumapeto onse a thupi la valavu, omwe amafanana ndi ma flanges omwe ali papayipi, ndipo amaikidwa mupayipi poika ma flanges. Kulumikizana kwa flange ndi njira yolumikizira yomwe imagwiritsidwa ntchito kwambiri mu ma valavu. Ma flanges amagawidwa m'magulu awiri: convex surface (RF), flat surface (FF), convex ndi concave surface (MF), ndi zina zotero.
B. Kulumikizana kwa wafer
Vavu imayikidwa pakati pa ma flange awiri, ndipo thupi la vavu lavalavu ya gulugufe ya wafernthawi zambiri imakhala ndi dzenje loyikapo malo kuti ithandize kukhazikitsa ndi kuyiyika.
C. Kulumikizana kwa solder
(1) Kulumikiza matako: Malekezero onse awiri a thupi la valavu amakonzedwa kukhala ma tako olumikizira matako molingana ndi zofunikira pa matako olumikizira matako, zomwe zimagwirizana ndi matako olumikizira matako a payipi, ndipo zimakhazikika pa payipi mwa kuwotcherera.
(2) Kulumikiza soketi yolumikizira: Malekezero onse awiri a thupi la valavu amakonzedwa molingana ndi zofunikira za soketi yolumikizira, ndipo amalumikizidwa ndi payipi pogwiritsa ntchito soketi yolumikizira.
D. Kulumikizana kolumikizidwa ndi ulusi
Kulumikiza kwa ulusi ndi njira yosavuta yolumikizira ndipo nthawi zambiri imagwiritsidwa ntchito pa ma valve ang'onoang'ono. Thupi la valavu limakonzedwa motsatira muyezo uliwonse wa ulusi, ndipo pali mitundu iwiri ya ulusi wamkati ndi ulusi wakunja. Zimafanana ndi ulusi womwe uli pa chitoliro. Pali mitundu iwiri ya kulumikiza kwa ulusi:
(1) Kutseka mwachindunji: Ulusi wamkati ndi wakunja umagwira ntchito yotseka mwachindunji. Pofuna kuonetsetsa kuti kulumikizana sikutuluka, nthawi zambiri kumadzazidwa ndi mafuta a lead, thread hemp ndi tepi ya PTFE ya raw material; pakati pawo tepi ya PTFE ya raw material imagwiritsidwa ntchito kwambiri; zinthuzi zimakhala ndi kukana dzimbiri komanso zotsatira zabwino kwambiri zotseka. N'zosavuta kugwiritsa ntchito ndikusunga. Mukachotsa, zimatha kuchotsedwa kwathunthu chifukwa ndi filimu yosamata, yomwe ndi yabwino kwambiri kuposa mafuta a lead ndi thread hemp.
(2) Kutseka kosalunjika: mphamvu ya kulimbitsa ulusi imatumizidwa ku gasket pakati pa ndege ziwirizi, kotero kuti gasket imagwira ntchito yotseka.
Kulumikizana kwa E. ferrule
Kulumikizana kwa ferrule kwangopangidwa kumene m'dziko langa m'zaka zaposachedwa. Mfundo yake yolumikizira ndi kutseka ndi yakuti pamene nati yalimbikitsidwa, ferrule imakakamizidwa, kotero kuti m'mphepete mwa ferrule imaluma khoma lakunja la chitoliro, ndipo pamwamba pa phiri lakunja la ferrule limalumikizidwa ndi cholumikizira pansi pa kukakamizidwa. Mkati mwa thupi muli pafupi ndi pamwamba pochepa, kotero kutuluka kumatha kupewedwa modalirika. Monga ma valve a zida. Ubwino wa njira iyi yolumikizira ndi:
(1) Kukula kochepa, kulemera kopepuka, kapangidwe kosavuta, kusweka mosavuta ndi kusonkhana;
(2) Mphamvu yolumikizira yamphamvu, kugwiritsa ntchito mosiyanasiyana, kukana kuthamanga kwambiri (1000 kg/cm2), kutentha kwambiri (650 ° C) komanso kugwedezeka ndi kugwedezeka;
(3) Zipangizo zosiyanasiyana zitha kusankhidwa, zoyenera kuletsa dzimbiri;
(4) Zofunikira pa kulondola kwa makina si zapamwamba;
(5) Ndi yabwino kuyika pamalo okwera kwambiri.
Pakadali pano, njira yolumikizira ferrule yagwiritsidwa ntchito pazinthu zina zazing'ono zama valve mdziko langa.
F. Kulumikizana kolumikizidwa
Iyi ndi njira yolumikizira mwachangu, imangofunika mabotolo awiri okha, ndipovalavu ya gulugufe yozungulirandi yoyenera kupanikizika kochepamavavu a gulugufezomwe nthawi zambiri zimaphwanyidwa, monga ma valve a ukhondo.
G. Kulumikizana kodzilimbitsa mkati
Mitundu yonse yolumikizira yomwe ili pamwambapa imagwiritsa ntchito mphamvu yakunja kuti ichepetse kupanikizika kwa cholumikizira kuti chitseke. Zotsatirazi zikufotokoza njira yolumikizira yokha pogwiritsa ntchito kupanikizika kwapakati.
Mphete yake yotsekera imayikidwa pa kondomu yamkati ndipo imapanga ngodya inayake pomwe mbali ikuyang'ana pakati. Kupanikizika kwa kondomu kumatumizidwa ku kondomu yamkati kenako ku mphete yotsekera. Pamwamba pa kondomu ya ngodya inayake, mphamvu ziwiri zimapangidwa, imodzi yokhala ndi Mzere wapakati wa thupi la kondomu uli wofanana ndi wakunja, ndipo inayo imakanikizidwa pakhoma lamkati la thupi la kondomu. Mphamvu yomalizayi ndi mphamvu yodzilimbitsa yokha. Kupanikizika kwapakati kukakhala kwakukulu, mphamvu yodzilimbitsa yokha imakhala yayikulu. Chifukwa chake, mawonekedwe olumikizira awa ndi oyenera ma kondomu amphamvu kwambiri.
Poyerekeza ndi kulumikizana kwa flange, imasunga zinthu zambiri ndi mphamvu ya anthu, komanso imafunanso kuyikapo katundu wina, kuti igwiritsidwe ntchito moyenera pamene kupanikizika mu valavu sikuli kokwera. Ma valavu opangidwa pogwiritsa ntchito mfundo yodzimangira yokha nthawi zambiri amakhala ma valavu okhala ndi mphamvu yamphamvu.
Pali mitundu yambiri yolumikizira ma valavu, mwachitsanzo, ma valavu ang'onoang'ono omwe safunika kuchotsedwa amalumikizidwa ndi mapaipi; ma valavu ena osakhala achitsulo amalumikizidwa ndi soketi ndi zina zotero. Ogwiritsa ntchito ma valavu ayenera kuthandizidwa malinga ndi momwe zinthu zilili.
Zindikirani:
(1) Njira zonse zolumikizira ziyenera kutsata miyezo yoyenera ndikulongosola miyezo kuti valavu yosankhidwa isayikidwe.
(2) Kawirikawiri, payipi yaikulu ndi valavu zimalumikizidwa ndi flange, ndipo payipi yaying'ono ndi valavu zimalumikizidwa ndi ulusi.
