Swing check valve ndi valavu yomwe nthawi zambiri imalola madzi (madzi kapena mpweya) kuyenda modutsa njira imodzi ndikuletsa kutuluka kwina. Iwo chimagwiritsidwa ntchito mafuta, mankhwala, chakudya, mankhwala, nsalu, mphamvu, m'madzi, zitsulo, kachitidwe mphamvu, etc.
Chimbale cha ma valve cheke cha swing chimakhala chozungulira; imapanga mayendedwe ozungulira pamzere wapakati wa shaft wochitidwa ndi kuthamanga kwamadzimadzi, madzimadzi amayenda kuchokera kumbali yolowera kupita ku mbali yotulukira. Pamene kulowetsedwa kolowera kumakhala kochepa kusiyana ndi kuthamanga kwa kutuluka, diski yake imatha kutseka yokha chifukwa cha zinthu monga kusiyana kwa kuthamanga kwa madzi ndi kufa kuti madzi asabwererenso;
Zomangamanga zazikulu za JLPV Swing check valve ndi izi:
1.Mapangidwe opangidwa ndi trim
Valavu yowunikira ya JLPV imatenga mawonekedwe omangika. Disiki ya valve ndi hinge mkono zonse zili mkati mwa chipinda chake chamkati, motero sichimakhudza kuyenda kwake ndikuchepetsa kutayikira kwake;
2. Integral forged kapena anagulung'undisa thupi mpando kapena mpando welded ndi wokutidwa mu mitundu ya zinthu
Kuphimba ndi welded kumangotengera njira zovomerezeka za WPS. Pambuyo pa kuwotcherera ndi kutenthetsa zonse zofunika, mphete yapampando imapangidwa ndi makina, kutsukidwa bwino ndikuyang'aniridwa musananyamuke.
3.Kukula kwakukulu kumaperekedwa ndi mphete yonyamulira yokweza, motero kumakhala kosavuta kuyika; Mavavu a swing cheque amatha kukhazikitsidwa molunjika kapena molunjika.
Mitundu yosiyanasiyana ya JLPV Swing check valve design ili motere:
1.Kukula: 2 "mpaka 48" DN50 mpaka DN1200
2.Kupanikizika:Kalasi 150lb mpaka 2500lb PN10-PN420
3.Zinthu: Chitsulo cha carbon ndi chitsulo chosapanga dzimbiri ndi zipangizo zina zapadera.
NACE MR 0175 anti-sulfure ndi anti-corrosion zitsulo zipangizo
4.Kulumikizana kumatha: ASME B 16.5 mu nkhope yokwezeka (RF), Flat face (FF) ndi Ring Type Joint (RTJ)
ASME B 16.25 mu matako kuwotcherera malekezero.
5.Kukula kwa nkhope ndi nkhope: kugwirizana ndi ASME B 16.10.
6.Kutentha: -29 ℃ mpaka 425 ℃
