Kulumikizana kwa valavu ndi thupi la valve lomwe lili ndi ma flange mbali zonse ziwiri, zogwirizana ndi ma flanges pa payipi, pomangirira flange yomwe imayikidwa mu payipi. Kulumikizana kwa ma valve ndi njira yomwe imagwiritsidwa ntchito kwambiri. Flanges ali ndi convex (RF), ndege (FF), convex ndi concave (MF) ndi mfundo zina. Malinga ndi mawonekedwe a pamwamba olowa, akhoza kugawidwa m'magulu awa:
(1) yosalala mtundu: kwa valavu ndi otsika kuthamanga. Processing ndi yabwino;
(2) concave ndi otukukira m'mimba mtundu: mkulu ntchito kuthamanga, angagwiritse ntchito gasket zolimba;
(3) tenon poyambira mtundu: gasket ndi mapindikidwe lalikulu pulasitiki angagwiritsidwe ntchito kwambiri TV zikuwononga, ndi kusindikiza zotsatira bwino;
(4) trapezoidal poyambira mtundu: chowulungika zitsulo mphete monga gasket, ntchito valavu ntchito kuthamanga ≥64 makilogalamu/cm2, kapena valavu mkulu kutentha;
(5) Mtundu wa mandala: gasket ndi mawonekedwe a lens, opangidwa ndi chitsulo. Ntchito mavavu mkulu kuthamanga ndi kuthamanga ntchito ≥ 100kg/cm2, kapena valavu kutentha;
(6) Mtundu wa O-ring: uwu ndi mtundu watsopano wa kugwirizana kwa flange, ndi kutuluka kwa mitundu yonse ya mphira ya O-ring, ndikukula, ndi yodalirika kwambiri pakusindikiza kuposa gasket yamoto.
(1) Kuwotcherera matako: malekezero onse a thupi valavu kukonzedwa mu matako-kuwotcherera poyambira malinga ndi zofunika kuwotcherera matako, lolingana ndi chitoliro kuwotcherera poyambira, ndipo anakonza pa payipi kudzera kuwotcherera.
(2) zitsulo zowotcherera zitsulo: malekezero onse a thupi la valve amakonzedwa molingana ndi zofunikira zazitsulo zowotcherera komanso zogwirizana ndi payipi kupyolera muzitsulo zowotcherera.
Kulumikizana kwa ulusi ndi njira yabwino yolumikizirana ndipo nthawi zambiri imagwiritsidwa ntchito pama valve ang'onoang'ono. Thupi la valve limakonzedwa molingana ndi ulusi wokhazikika, ndipo pali mitundu iwiri ya ulusi wamkati ndi ulusi wakunja. Zogwirizana ndi ulusi pa chitoliro. Kugwirizana kwa ulusi kumagawidwa muzochitika ziwiri:
(1) kusindikiza mwachindunji: ulusi wamkati ndi wakunja mwachindunji umagwira ntchito yosindikiza. Pofuna kuonetsetsa kuti olowa si kutayikira, nthawi zambiri ndi mafuta lead, hemp ndi PTFE yaiwisi kudzaza lamba; Pakati pawo, PTFE yaiwisi lamba chimagwiritsidwa ntchito. Nkhaniyi imakhala ndi kukana kwa dzimbiri, kusindikiza bwino kwambiri, kosavuta kugwiritsa ntchito ndikusunga, ikatha, imatha kuchotsedwa kwathunthu, chifukwa ndi filimu yopanda viscous, yabwino kuposa mafuta otsogolera, hemp.
(2) kusindikiza kwachindunji: mphamvu ya zomangira zomangira zimaperekedwa ku gasket pakati pa ndege ziwirizi, kotero kuti gasket imagwira ntchito yosindikiza.
Pali mitundu isanu ya ulusi womwe amagwiritsidwa ntchito kwambiri:
(1) Metric common thread;
(2) Inchi wamba;
(3) Ulusi wosindikiza ulusi wa chitoliro;
(4) ulusi wosindikizira wopanda ulusi;
(5) Ulusi wa chitoliro waku America.
Mawu oyamba ndi awa:
① Muyezo wapadziko lonse wa ISO228/1, DIN259, wa ulusi wofananira wamkati ndi kunja, kachidindo G kapena PF(BSP.F);
② Muyezo waku Germany wa ISO7/1, DIN2999, BS21, wakunja kwa dzino, ulusi wamkati wofanana ndi dzino, kachidindo BSP.P kapena RP/PS;
③ British muyezo ISO7/1, BS21, mkati ndi kunja taper ulusi, code PT kapena BSP.TR kapena RC;
④ American standard ANSI B21, mkati ndi kunja taper ulusi, code NPT G (PF), RP(PS), RC (PT) mano Angle ndi 55 °, NPT dzino ngodya ndi 60 ° BSP.F, BSP.P ndi BSP. TR pamodzi amatchedwa BSP mano.
Pali mitundu isanu ya ulusi wa chitoliro wokhazikika ku United States: NPT yogwiritsidwa ntchito wamba, NPSC ya ulusi wowongoka wamkati wa chitoliro cholumikizira, NPTR yolumikizira ndodo zowongolera, NPSM ya ulusi wa chitoliro wowongoka wamakina olumikizira (zolumikizira zaulere zamakina), ndi NPSL kwa lotayirira koyenera makina kugwirizana ndi zokhoma mtedza. Ndi ya ulusi wa chitoliro chosamata (N: American national standard; P: pipe; T: Taper)
4 .Taper kugwirizana
Kulumikizana ndi kusindikiza Mfundo ya manja ndi yakuti pamene nati imangiriridwa, mkonowo umakhala wopanikizika, kotero kuti m'mphepete mwake mumakhala khoma lakunja la chitoliro, ndipo khola lakunja la manja limatsekedwa mwamphamvu ndi cone. olowa thupi pansi pampanipani, kotero izo zikhoza kuteteza kutayikira. Mongama valve opangira zida.Ubwino wa njira yolumikizira iyi ndi:
(1) Voliyumu yaying'ono, kulemera kopepuka, kapangidwe kosavuta, kusokoneza kosavuta ndi kusonkhana;
(2) relay amphamvu, osiyanasiyana ntchito, akhoza kupirira kuthamanga (1000 makilogalamu/square centimita), kutentha (650 ℃) ndi kugwedezeka kwamphamvu;
(3) akhoza kusankha zipangizo zosiyanasiyana, zoyenera kupewa dzimbiri;
(4) kulondola kwa Machining sikwapamwamba;
(5) zosavuta kukhazikitsa pamalo okwera.
5. Kulumikizana kwa clamp
Ndi njira yolumikizira yofulumira yomwe imafuna ma bolts awiri okha ndipo ndiyoyenera ma valve otsika omwe nthawi zambiri amachotsedwa.
