Pa ma valve otsegula kapena otsekedwa kwathunthu, ma valve a zipata amagwiritsidwa ntchito.Amagwiritsidwa ntchito mobwerezabwereza kwa madzi, nthunzi, mafuta opangira mafuta, etc. osati throttling.Iwo amagwiritsidwa ntchito kwambiri m'mafakitale a petroleum, mankhwala, chakudya, mankhwala, nsalu, mphamvu, m'madzi, zitsulo, ndi magetsi, pakati pa ena.
Mavavu a pachipata amakhala ndi mphero yosuntha yomwe imayenda motsatira kayendedwe ka tsinde.Mphepeteyo imasuntha molunjika kumayendedwe ake.
Ma valve a zipata nthawi zambiri amakhala ndi vuto locheperako akamatseguka kwathunthu ndipo amatseka mwamphamvu akatsekedwa kwathunthu chifukwa cha kusindikiza kwawo kawiri.
Zomangamanga zazikulu za valve yachipata ya JLPV ndi izi:
1.Pali ma wedge okhazikika a chidutswa chimodzi, mapangidwe olimba a wedge, ndi ma wedge awiri.
Ma wedges osinthika amtundu umodzi amatha kubwezeretsanso kukula kwamafuta ndi mapindikidwe ang'onoang'ono a elasto-matenthedwe, kuonetsetsa kuti nthawi zonse, kukhudzana bwino ndi mipando ndikukhalabe olimba pamipando yosiyanasiyana komanso kutentha.
2.Mpando wokhala ndi thupi lophatikizika kapena mpando womwe umalumikizidwa ndi zida zosiyanasiyana
Ma protocol a WPS atsatiridwa mwamphamvu pakuphimba ndi welded.Nkhope za mphete zapampando zimapangidwa ndi makina, kutsukidwa mosamala, ndikuwunikiridwa musananyamuke potsatira kuwotcherera ndi kuwotcherera kulikonse kofunikira.
3.Kuphatikizana T-mutu tsinde ndi pamwamba bonnet chisindikizo komanso kunyamula chisindikizo
Maonekedwe amtundu wa T-mutu wa tsinde amakhala ngati cholumikizira pachipata.Ndi kulimba kwenikweni m'dera lolongedza katundu komanso moyo wautali chifukwa cha miyeso yolondola ndi zomaliza, kumatulutsa mpweya wocheperako.
Mapangidwe a ma valve a pakhomo la JLPV ali 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 ℃
Ma valve a JLPV amatha kupangidwa mumitundu yonse yazinthu kuti akwaniritse zofunikira zosiyanasiyana kuchokera kwa makasitomala, makamaka mulingo wa NACE.
Mavavu a JLPV amatha kukhala ndi zida zamagetsi, ma pneumatic actuators, ma Hydraulic actuators, Magetsi, ma bypass, zida zotsekera, ma chainwheel, zimayambira zowonjezera ndi zina zambiri zilipo kuti zikwaniritse zosowa za makasitomala.
