Pali zosiyana zingapo panjira ya ma valve osindikiza osindikizira.Kawirikawiri, madzimadzi amadulidwa pogwiritsa ntchito mtundu womwewo.Kutembenuka kwamadzimadzi kungathe kuchitidwa ndi ma valve a plug-way atatu ndi anayi. Kuti mutsegule ndi kutseka njira, chigawo chotsegulira ndi kutseka kwa tambala ndi silinda yokhala ndi mabowo omwe amazungulira mozungulira mozungulira pa njira.Pogwiritsa ntchito ma valve osindikizira osindikizira, mapaipi ndi zipangizo zamakono zimatha kutsegulidwa ndi kutsekedwa.
Kagwiritsidwe ntchito ka valavu ya pulagi yosindikizira yofewa:
Ma valve Soft seal plug nthawi zambiri amagwiritsidwa ntchito m'malo owononga, owopsa kwambiri, komanso owopsa komanso malo ena ovuta.Ndizoletsedwa kuti ma valve awa atayike panthawiyi, ndipo zida za valve sizidzaipitsa zofalitsa.Sing'anga yogwirira ntchito imatha kulamula ngati chitsulo cha kaboni, chitsulo cha alloy, kapena chitsulo chosapanga dzimbiri chiyenera kugwiritsidwa ntchito pathupi la valve.
Zomangamanga zazikulu za valavu ya pulagi ya JLPV ndi izi:
1. Yoyenera kugwira ntchito pafupipafupi, kutsegula ndi kutseka mwamsanga, kuwala.
2. Soft seal plug valve fluid kukana ndi kochepa.
3. Mapangidwe osavuta, voliyumu yaying'ono, kulemera kwake, kukonza kosavuta.
4. Soft seal plug valve yosindikiza ntchito ndi yabwino.
5. Osachepera ndi malangizo oyika, kutuluka kwa sing'anga kungakhale kopanda malire.
6. Palibe kugwedezeka, phokoso lochepa.
Mapangidwe a ma valve a plug a JLPV ali motere:
1. Kukula: 2 "mpaka 14" DN50 mpaka DN350
2. Kupanikizika: Kalasi 150lb mpaka 900lb PN10-PN160
3. Zinthu: zitsulo za carbon, zitsulo zosapanga dzimbiri ndi zitsulo zina zomwe zimagwiritsidwa ntchito.
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 m'mapeto opotoka.
5. Miyezo ya nkhope ndi maso: igwirizane ndi ASME B 16.10.
6. Kutentha: -29 ℃ mpaka 180 ℃
Ma valve a JLPV amatha kukhala ndi zida zamagetsi, ma pneumatic actuators, ma hydraulic actuators, magetsi oyendetsa magetsi, zodutsa, zida zokhoma, ma chainwheel, zimayambira zokulirapo ndi zina zambiri zilipo kuti zikwaniritse zosowa za makasitomala.
