PTFE PFA Lining Butterfly Valve

ZFAMavavu agulugufe okhala ndi fluorine, ndi imodzi mwamankhwala onseyopangidwa ndi ZFA VALVE.PTFE Lining Valve yomwe imadziwikanso kuti fluorine pulasitiki yokhala ndi dzimbiri zosagwira mavavu, ndi pulasitiki ya fluorine yomwe imapangidwira mkati mwa khoma lamkati lazitsulo kapena zitsulo zokhala ndi valavu kapena kunja kwa mbali zamkati za valve.Mapulasitiki a fluorine apa makamaka akuphatikizapo: PTFE, PFA, FEP ndi ena.Gulugufe wokhala ndi FEP, valavu yagulugufe yokhala ndi teflon ndi valavu yagulugufe ya FEP nthawi zambiri amagwiritsidwa ntchito popanga zida zowononga kwambiri.

 

Vavu yagulugufe yokhala ndi fluorine ndi imodzi mwazinthu zazikulu zamavavu a ZFA.Magulu athu atatu ndi awa:

1. Malingana ndi mapangidwe a thupi la valve, likhoza kugawidwa mumtundu umodzi ndi mtundu wa magawo awiri.

2. Malinga ndi akalowa angathenso kugawidwa mu mzere mokwanira ndi theka mzere.Vavu yagulugufe yokhala ndi mzere wokwanira ndi thupi la valavu ndipo mbale ya valve imayikidwa ndi mphira;theka laling'ono limatanthawuza kungoyika thupi la valve.

3. Malinga ndi mtunduwo, ma valve agulugufe okhala ndi Teflon amatha kugawidwavalavu yagulugufe yokhala ndi fluorine, valavu yokhala ndi agulugufe wa fluorine ndi valavu ya butterfly ya flange.

 

Ma valve agulugufe okhala ndi fluorine:

1. PTFE/PFA/FEP yokhala ndi mizere yokwanira kapena yokhazikika.

2. Teflon ali ndi gulugufe valavu, oyenera poizoni ndi zikuwononga kwambiri mankhwala sing'anga.

3. Pambuyo kusindikiza mobwerezabwereza mayesero otetezera, PTFE yokhala valavu yagulugufe ilibe kuipitsa chilengedwe.

4. Zochotseka zogawanika kapangidwe kamangidwe.(Mwasankha)

5. Mlingo wa kutchinjiriza umagwirizana ndi malamulo a zida.

6. Ikhoza kukhazikitsidwa pamalo aliwonse;Yopanda kukonza ndipo imatha kukwaniritsa zofunikira pazovuta zosiyanasiyana zogwirira ntchito.

7. Zochotseka, zida zitha kubwezeretsedwanso.

8. Nkhaniyi ikugwirizana ndi miyezo ya FDA.

9. Kuchita mwachidwi ndi ntchito yabwino yosindikiza.

10. Kapangidwe kake ndi kosavuta komanso kophatikizana, kowoneka bwino.

11. Zida zosindikizira zimagonjetsedwa ndi ukalamba ndi dzimbiri, ndi moyo wautali wautumiki.
