Mitundu yolumikizana yodziwika bwino ya vacuum vacuum

1. Kulumikizana kwa Flange

Uwu ndiye njira yomwe imagwiritsidwa ntchito kwambiri polumikizira ma valve.Malinga ndi mawonekedwe a pamwamba olowa, akhoza kugawidwa m'magulu awa:

● Mtundu wosalala: umagwiritsidwa ntchito pa valavu yokhala ndi mphamvu yochepa komanso yabwino kukonza.

● Mtundu wa concave convex: mphamvu yogwira ntchito ndiyokwera kwambiri, ndipo makina ochapira apakati angagwiritsidwe ntchito.

● Mtundu wa Tenon groove: washer wokhala ndi pulasitiki wamkulu wopindika ungagwiritsidwe ntchito, womwe umagwiritsidwa ntchito kwambiri m'kati zowonongeka ndipo uli ndi zotsatira zabwino zosindikizira.

● Trapezoidal groove mtundu: ntchito elliptical zitsulo mphete monga gasket, ndi ntchito valavu ndi ntchito kuthamanga ≥ 64kg / cm2 kapena valavu mkulu kutentha.

● Mtundu wa lens: gasket ndi mawonekedwe a lens, opangidwa ndi chitsulo.Pakuti valavu mkulu kuthamanga kapena valavu mkulu kutentha ndi kuthamanga ntchito ≥ 100kg / cm2.

● Mtundu wa O-ring: Iyi ndi njira yatsopano yolumikizira flange, yomwe imapangidwa ndi kutuluka kwa ma O-rings osiyanasiyana.Ndi odalirika kuposa wamba lathyathyathya gasket mu kusindikiza kwenikweni.

2 Kulumikizana kwa ulusi

Iyi ndi njira yosavuta yolumikizira, yomwe imagwiritsidwa ntchito kwambiri pama valve ang'onoang'ono.Pali zochitika ziwiri:

● Kusindikiza mwachindunji: ulusi wamkati ndi wakunja umagwira ntchito mwachindunji kusindikiza.Pofuna kuonetsetsa kuti palibe kutayikira pa olowa, mafuta otsogolera, hemp ya ulusi ndi lamba wa polytetrafluoroethylene raw material amagwiritsidwa ntchito podzaza.Pakati pawo, lamba wa polytetrafluoroethylene wamba amagwiritsidwa ntchito kwambiri.Nkhaniyi ili ndi kukana kwa dzimbiri, kusindikiza bwino kwambiri, kugwiritsa ntchito bwino komanso kusungidwa.Pochotsa, imatha kuchotsedwa kwathunthu, chifukwa ndi filimu yosakanirira, yomwe ili yabwino kwambiri kuposa mafuta am'tsogolo ndi ulusi wa hemp.

● Kusindikiza kosalunjika: mphamvu yomangirira ulusi imatumizidwa ku gasket pakati pa ndege ziwiri kuti gasket igwire ntchito yosindikiza.

3 Kulumikizana kwa Ferrule

Kulumikizana kwa ferrule kwachitika zaka zaposachedwa ku China.Ubwino wa mawonekedwe olumikizana awa ndi awa:

● Voliyumu yaying'ono, kulemera kopepuka, kapangidwe kosavuta komanso kosavuta disassembly;

● Mphamvu yolumikizira yamphamvu, yochuluka yogwiritsira ntchito, ndipo imatha kupirira kuthamanga kwambiri (1000 kg / cm2), kutentha kwakukulu (650 ° C) ndi kugwedezeka kwamphamvu;

● Zida zosiyanasiyana zimatha kusankhidwa, zoyenera zotsutsana ndi dzimbiri;

● Zofunikira pakukonza zolondola sizokwera;

● Ndi yabwino kukhazikitsa okwera.Pakalipano, mawonekedwe a ferrule kugwirizana kwagwiritsidwa ntchito muzinthu zina zazing'ono za valve ku China.

4 Kulumikizana kwamphamvu

Iyi ndi njira yolumikizira mwachangu, imangofunika ma bolts awiri, omwe ndi oyenera ma valve otsika omwe nthawi zambiri amasokonekera.

5 Mgwirizano wokhazikika wamkati

Mosiyana ndi njira zina zolumikizirana, mphamvu yakunja imagwiritsidwa ntchito polimbana ndi kukakamiza kwapakatikati kuti akwaniritse kusindikiza.Mphete yosindikiza imayikidwa pa cone yamkati, kupanga digiri inayake ndi nkhope yotsutsana ndi sing'anga.Kupanikizika kwapakatikati kumaperekedwa ku cone yamkati, ndiyeno ku mphete yosindikiza.Pamwamba pa conical ndi ngodya yokhazikika, zigawo ziwiri zimapangidwira, chimodzi chikufanana ndi mzere wapakati wa thupi la valve ndipo china chimakanikizidwa ku khoma lamkati la thupi la valve.Chigawo chomaliza ndi mphamvu yodzilimbitsa yokha.Kuchuluka kwa mphamvu yapakatikati, kumapangitsanso kudzilimbitsa kwambiri.Chifukwa chake kulumikizana kwamtunduwu ndikoyenera valavu yothamanga kwambiri.Poyerekeza ndi kugwirizana kwa flange, ikhoza kupulumutsa zipangizo zambiri ndi anthu ogwira ntchito, koma imafunikanso mphamvu yowonjezereka, kuti igwiritsidwe ntchito modalirika pamene kupanikizika kwa valve sikuli kwakukulu.

Pali mitundu yambiri yolumikizira ma valve, mwachitsanzo, ma valve ena ang'onoang'ono omwe safunikira kuchotsedwa amawotchedwa ndi mapaipi;ma valve ena omwe si azitsulo amatengera kulumikiza zitsulo, etc. Ogwiritsa ntchito ma valve ayenera kuthandizidwa malinga ndi zikhalidwe zina.
