Malinga ndi mawonekedwe a kugwirizana kwa flange, agulugufe vavu thupiAmagawidwa kukhala: chophika chamtundu A, chophwanyika chamtundu wa LT, flange imodzi, flange iwiri, U mtundu wa flange.
Mtundu wa Wafer A ndiwolumikizana ndi dzenje lopanda ulusi, LT mtundu wa 24" pamwamba pazidziwitso zazikulu nthawi zambiri amagwiritsa ntchito mphamvu ya U-mtundu wa valve kuti alumikizane ndi ulusi, kumapeto kwa payipi kumafunika kugwiritsa ntchito mtundu wa LT.
Malinga ndi mawonekedwe osindikizira, thegulugufe vavu thupiatha kugawidwa mu mphira vulcanized thupi (yosasinthika mpando thupi), thupi valavu ogawanika (nthawi zambiri ndi mpando dzimbiri zosagwira), ndi m'malo thupi mpando (yolimba kumbuyo mpando ndi mpando ofewa).
Zida zomwe timagwiritsa ntchito kwambiri pamavavu agulugufe kwambiri ndizo: chitsulo chopangidwa ndi chitsulo, chitsulo cha ductile, thupi lachitsulo chosapanga dzimbiri, thupi lachitsulo chosapanga dzimbiri, thupi la mkuwa, thupi la aluminiyamu komanso thupi lachitsulo lopangidwa ndi duplex.
Chitsulo chachitsulo: Zomwe zimagwiritsidwa ntchito kwambiri mkati mwa valavu yagulugufe, zomwe zimagwiritsidwa ntchito kwambiri m'madzi, zosavuta kuwononga, moyo waufupi, wotchipa.
Chitsulo choponyera: Chitsulo chotaya ndi choyenera kukakamiza mwadzina PN ≤ 1.0MPa, kutentha -10 ℃ ~ 200 ℃ madzi, nthunzi, mpweya, gasi ndi mafuta ndi media zina.Miyezo ndi magiredi otuwa omwe amagwiritsidwa ntchito kwambiri ndi awa: GB/T 12226, HT200, HT250, HT300, HT350.
Chitsulo chachitsulo: Mu valavu ya butterfly ntchito ikufanana ndi chitsulo cha carbon, chomwe chimagwiritsidwa ntchito kwambiri pamapaipi a madzi, komanso pakalipano njira yamadzi yogwiritsira ntchito zipangizo zosiyanasiyana.
Ductile chitsulo: Oyenera PN ≤ 2.5MPa, kutentha -30 ~ 350 ℃ madzi, nthunzi, mpweya ndi mafuta ndi zina.Zomwe zimagwiritsidwa ntchito nthawi zambiri ndi: GB/T12227:2005 QT400-15, QT450-10, QT500-7;EN1563 EN-GJS-400-15,ASTM A536,65 45-12,ASTM A395,65 45 12.
Chitsulo cha kaboni: Itha kugwiritsidwanso ntchito m'madzi, valavu yagulugufe ya kaboni imakhala ndi kutentha kwambiri komanso kukana kukakamizidwa, valavu yagulugufe yolimba kwambiri yokhala ndi chitsulo cha kaboni.
Mpweya zitsulo: Oyenera mwadzina kuthamanga PN ≤ 3.2MPa, kutentha -30 ~ 425 ℃ madzi, nthunzi, mpweya, haidrojeni, ammonia, nayitrogeni ndi mafuta mafuta ndi sing'anga zina.Ambiri ntchito sukulu ndi mfundo ndi ASTM A216/216M: 2018WCA, WCB, ZG25 ndi apamwamba zitsulo 20, 25, 30 ndi otsika aloyi structural zitsulo 16MN.
Chitsulo chosapanga dzimbiri: Mavavu agulugufe a chitsulo chosapanga dzimbiri ali ndi dzimbiri labwino kwambiri komanso kukana dzimbiri, ndipo amagwiritsidwanso ntchito kwambiri pamapaipi omwe amafunikira dzimbiri komanso dzimbiri, ndipo mtengo wake ndi wokwera kwambiri.Imagwiritsidwa ntchito kukakamiza mwadzina PN ≤ 6.4.0MPa, kutentha osiyanasiyana: -268 ° C mpaka +425 ° C, nthawi zambiri amagwiritsidwa ntchito m'madzi, m'madzi a m'nyanja, m'makampani opanga mankhwala, mafuta ndi gasi, mankhwala, sing'anga ya chakudya.Miyezo wamba ndi magiredi: ASTM A351/351M:2018, SUS304,304, SUS316, 316
Copper aloyi: Copper aloyi butterfly valavu ndi oyenera PN ≤ 2.5MPa madzi, madzi a m'nyanja, mpweya, mpweya, mafuta ndi sing'anga zina, komanso TV nthunzi pa kutentha kwa -40 ~ 250 ℃, ambiri ntchito sukulu ZGnSn10Zn2 (malata mkuwa ), H62, Hpb59-1 (mkuwa), QAZ19-2, QA19-4 (aluminium bronze).Miyezo wamba ndi magiredi: ASTM B148:2014, UNS C95400, UNS C95500, UNS C95800;ASTM B150 C6300.
