Malinga ndi mawonekedwe olumikizira flange,thupi la valavu ya gulugufeAmagawidwa makamaka m'magulu awa: wafer mtundu A, wafer mtundu LT, single flange, double flange, U mtundu flange.
Mtundu wa Wafer A ndi wolumikizira mabowo osalumikizidwa, mtundu wa LT 24" pamwamba pa specifications zazikulu nthawi zambiri umagwiritsa ntchito mphamvu yabwino ya thupi la valavu ya U kuti ulumikizane ndi ulusi, kumapeto kwa payipi kumafunika kugwiritsa ntchito mtundu wa LT.
Malinga ndi kapangidwe ka kutseka,thupi la valavu ya gulugufeZingagawidwe m'magulu awiri: thupi la rabara losasinthika (thupi la mpando losasinthika), thupi la valavu logawanika (nthawi zambiri lokhala ndi mpando wosagonjetsedwa ndi dzimbiri), ndi thupi la mpando losinthika (lokhala ndi mpando wolimba kumbuyo ndi mpando wofewa).
Zinthu zomwe zimagwiritsidwa ntchito kwambiri mu ma valve a gulugufe ndi izi: chitsulo chosungunuka, chitsulo chosungunuka, thupi lachitsulo chosungunuka, thupi lachitsulo chosapanga dzimbiri, thupi la mkuwa, thupi la aluminiyamu ndi thupi lachitsulo chosungunuka.
Chitsulo chopangidwa ndi gulugufe: Chitsulo chogwiritsidwa ntchito kwambiri mkati mwa valavu ya gulugufe, chomwe chimagwiritsidwa ntchito kwambiri m'madzi, chosavuta kuwononga, nthawi yayitali yogwirira ntchito, komanso chotsika mtengo.
Chitsulo chopangidwa ndi imvi: Chitsulo chopangidwa ndi imvi chimagwiritsidwa ntchito pochiza PN ≤ 1.0MPa, kutentha -10 ℃ ~ 200 ℃ kwa madzi, nthunzi, mpweya, gasi ndi mafuta ndi zinthu zina. Miyezo ndi magiredi a imvi omwe amagwiritsidwa ntchito kwambiri ndi awa: GB/T 12226, HT200, HT250, HT300, HT350.
Chitsulo chodulira: Mu valavu ya gulugufe, magwiridwe antchito ake ndi ofanana ndi chitsulo cha kaboni, chomwe chimagwiritsidwa ntchito kwambiri mu payipi yamadzi, komanso pakadali pano madzi amagwiritsidwa ntchito pogwiritsa ntchito zipangizo zosiyanasiyana.
Chitsulo chopangidwa ndi ductile: Choyenera PN ≤ 2.5MPa, kutentha -30 ~ 350 ℃ madzi, nthunzi, mpweya ndi mafuta ndi zina zotero. Miyezo ndi magiredi omwe amagwiritsidwa ntchito kwambiri ndi awa: 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: Chingagwiritsidwenso ntchito m'madzi, valavu ya gulugufe ya kaboni imakhala ndi kutentha kwakukulu komanso kukana kuthamanga, valavu ya gulugufe yolimba kwambiri yokhala ndi zinthu zachitsulo cha kaboni.
Chitsulo cha kaboni: Choyenera kukanikiza PN ≤ 3.2MPa, kutentha -30 ~ 425 ℃ madzi, nthunzi, mpweya, haidrojeni, ammonia, nayitrogeni ndi zinthu zina zamafuta ndi zina. Magiredi ndi miyezo yomwe imagwiritsidwa ntchito kwambiri ndi ASTM A216/216M:2018WCA, WCB, ZG25 ndi chitsulo chapamwamba kwambiri 20, 25, 30 ndi chitsulo chotsika cha 16MN.
Chitsulo chosapanga dzimbiri: Ma valve a gulugufe osapanga dzimbiri ali ndi dzimbiri labwino kwambiri komanso kukana dzimbiri, ndipo amagwiritsidwanso ntchito kwambiri m'mapaipi omwe amafunika kukana dzimbiri ndi dzimbiri, ndipo mtengo wake ndi wokwera. Amagwiritsidwa ntchito pa PN ≤ 6.4.0MPa, kutentha kwake: -268 ° C mpaka +425 ° C, nthawi zambiri amagwiritsidwa ntchito m'madzi, m'madzi a m'nyanja, m'makampani opanga mankhwala, m'mafuta ndi gasi, m'mankhwala, m'malo osungira chakudya. Miyezo ndi magiredi ofanana: ASTM A351/351M:2018, SUS304,304, SUS316, 316
Chotsulo cha mkuwa: Valavu ya gulugufe ya aloyi ya mkuwa ndi yoyenera madzi a PN ≤ 2.5MPa, madzi a m'nyanja, mpweya, mpweya, mafuta ndi zina zotero, komanso nthunzi yotentha ya -40 ~ 250 ℃, magiredi omwe amagwiritsidwa ntchito kwambiri pa ZGnSn10Zn2 (mkuwa wa tin), H62, Hpb59-1 (mkuwa), QAZ19-2, QA19-4 (mkuwa wa aluminiyamu). Miyezo ndi magiredi ofanana: ASTM B148:2014, UNS C95400, UNS C95500, UNS C95800; ASTM B150 C6300.
