Ma valve a globe nthawi zambiri amagwiritsidwa ntchito ngati ma valve owongolera akamagwedeza kapena kuphatikiza kugwedeza ndi kutseka ndikofunikira. Amagwiritsidwa ntchito kwambiri pamapaipi osiyanasiyana, kuphatikizapo madzi, mafuta, mankhwala, chakudya, mankhwala, mphamvu, nyanja, zitsulo, ndi magetsi, pakati pa ena.
Chisindikizo cha valve yapadziko lonse lapansi chimapangidwa ndi malo osindikizira mpando komanso malo osindikizira a disc. Pamene tsinde likuzungulira, chimbalecho chimayenda molunjika pambali pa mpando wa valve.
Ntchito ya valavu yapadziko lonse lapansi ndikusindikiza sing'anga kuti isatayike pogwiritsa ntchito kukakamiza kwa tsinde la valavu kukakamiza malo osindikizira a disc ndi malo osindikizira mpando kuti agwirizane kwambiri.
Zotsatirazi ndizomwe zimapangidwira ma valve a JLPV globe:
1.Standard lathyathyathya chimbale kapangidwe kapena conical pulagi mtundu.
Tsinde ndi chimbale zimapota momasuka, ndipo chimbale chimakhala ndi ngodya yosiyana ndi mphete yapampando. Mtundu uwu umaganiziridwa kuti ndi wosavuta kukonza m'munda, umapereka chitsimikizo chapamwamba kwambiri chotseka, ndipo sichimakonda kukhala pampando wa thupi.
2.Mpando womwe uli mbali yofunika kwambiri ya thupi kapena mpando womwe umalumikizidwa ndi mitundu yosiyanasiyana ya zinthu.
Njira zovomerezedwa ndi WPS zimatsatiridwa bwino powotcherera pamwamba. Nkhope za mphete zapampando zimapangidwa ndi makina, kutsukidwa bwino, ndikuwunikiridwa pambuyo pa kuwotcherera ndi kutenthetsa kulikonse kofunikira musanasonkhanitsidwe.
3.Stem yokhala ndi chisindikizo chapamwamba cha bonnet ndi chisindikizo chonyamula. Diski ndi tsinde zimamangiriridwa ndi mtedza wa disc ndi mbale yokhala ndi mphete yogawanika.
The split-ring ring disc retainer ndi disc nut amagwiritsidwa ntchito kuti ateteze diski ku tsinde.Kutulutsa kothawa kwapansi kumakhala chifukwa cha miyeso ndi kumaliza kukhala kolondola chifukwa zimatsimikizira moyo wautali komanso zolimba kwambiri m'dera lonyamula.
Mtundu waMtengo wa JLPVMapangidwe a valve padziko lonse lapansi ali motere:
1.Kukula: 2 "mpaka 48" DN50 mpaka DN1200
2.Kupanikizika: Kalasi 150lb mpaka 2500lb PN16 mpaka 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 ℃
Mtengo wa JLPVma valve amatha kukhala ndi zida zamagetsi, ma pneumatic actuators, Hydraulic actuators, Magetsi, zodutsa, zida zokhoma, ma chainwheel, zimayambira ndi zina zambiri zilipo kuti zikwaniritse zosowa za makasitomala.
