Ma Valves a Metal Seat Ball amatengera zitsulo zonse kupanga zitsulo, malo osindikizira amakhala owumitsidwa mwapadera,
oyenera kutentha ndi kuthamanga kwambiri, TV olimba, moyo wautali, mkulu avale kukana zofunika, chimagwiritsidwa ntchito mafuta, mankhwala, chakudya, mankhwala, nsalu, mphamvu, sitima , Metallurgy, dongosolo mphamvu ndi mafakitale ena.
Zomangamanga zazikulu za JLPV zitsulo zapampando valavu ndi izi:
1. Thupi: 1PC, 2PC, 3PC ndi welded
2. Doko: Kubowola kwathunthu ndi kuchepetsedwa
3. Mtundu wa Mpira: Mpira woyandama ndi mpira wokhazikika
4. Mtundu wosindikiza: kusindikiza pampando wakutsogolo, kusindikiza pampando wakumbuyo, kusindikiza kwapampando wakumbuyo
5. Kusindikiza pamwamba: Mpira ndi mpando ukhoza kupopera zinthu zosiyanasiyana malinga ndi zofunikira, monga carbide kapena tungsten carbide, chromium carbide, etc.
6. Kapangidwe kampando kodzaza kasupe, konzani makokedwe
7. Moto wotetezedwa ndi anti-static design
Kasupe wa conductive amapangidwa pakati pa mpira ndi tsinde, tsinde ndi thupi, kotero mphamvu yosasunthika imatha kuyambitsidwa pansi kudzera munjira ya electrostatic kuti ikwaniritse cholinga chochotsa magetsi osasunthika.Pewani kuyatsa kwazinthu zoyaka moto kumatsimikizira chitetezo chadongosolo.
8. Tsinde losatsimikizira kuphulika, kapangidwe kake kothandizira kuchepetsa mphamvu, kapangidwe ka jekeseni wamafuta mwadzidzidzi, valavu yotsekera, chipangizo chotseka, kapangidwe ka anti-corrosion, kapangidwe ka anti-sulfure etc.
Tsinde limatenga mapangidwe okwera pansi kotero kuti tsinde lisawululidwe ndi sing'anga yothamanga kwambiri ngakhale kuthamanga kwamphamvu kwa thupi la vavu ndi kukwera kosavomerezeka;
Kupakako kumapanga mawonekedwe owoneka ngati V, omwe amatha kusintha bwino kupanikizika kwapakati kwamkati mwa thupi ndi mphamvu yotseka ya gland yakunja kukhala mphamvu yosindikiza ya tsinde la valavu.
Pamene sing'anga yosasunthika imawonjezera kupanikizika mosadziwika bwino chifukwa cha kusintha kwa kutentha, kupanikizika kwapakati kumakankhira mpando wa valve kutali ndi mpira kuti ukwaniritse zotsatira za mpumulo wodziwikiratu ndipo pambuyo pa kupanikizika, mpando wa valve ukhoza kuyambiranso.
Mavavu okhetsa amapangidwa kuti awone ngati mpando ukutuluka ndikutulutsa chotsekereza kuchokera m'bowolo kuti muchepetse kuipitsidwa kwapakati.
1.Mtundu wa JLPV chitsulo mpando valavu valavu zitsulo ndi motere:
2.Kukula: 2 "mpaka 48" DN50 mpaka DN1200
3.Kupanikizika: Kalasi 150lb mpaka 2500lb, PN16 mpaka PN420
4.Zinthu: Chitsulo cha carbon ndi chitsulo chosapanga dzimbiri ndi zipangizo zina zapadera.NACE MR 0175 anti-sulfure ndi anti-corrosion zitsulo zipangizo
5.Kulumikizana kumatha: ASME B 16.5 mu nkhope yokwezeka (RF), Flat face (FF) ndi Ring Type Joint (RTJ)
6.ASME B 16.25 mu matako kuwotcherera malekezero.
7.Kukula kwa nkhope ndi nkhope: kugwirizana ndi ASME B 16.10.
8.Kutentha: -29 ℃ mpaka 425 ℃
Mavavu a JLPV amatha kukhala ndi zida zamagetsi, ma pneumatic actuators, Hydraulic actuators, Magetsi, zodutsa, zida zotsekera, ma chainwheel, zimayambira zowonjezera ndi zina zambiri zilipo kuti zikwaniritse zosowa za makasitomala.
