PTFE PFA M'mphepete Gulugufe valavu

ZFAMa valve a gulugufe okhala ndi fluorine, ndi chimodzi mwazinthu zonseYopangidwa ndi ZFA VALVE. PTFE Lining Valve yomwe imadziwikanso kuti ma valve otetezedwa ndi dzimbiri okhala ndi fluorine pulasitiki, ndi pulasitiki ya fluorine yomwe imapangidwa mkati mwa khoma lamkati la zitsulo kapena zitsulo zonyamula valavu kapena pamwamba pa valavu yamkati. Mapulasitiki a fluorine pano makamaka ndi awa: PTFE, PFA, FEP ndi ena. Gulugufe wokhala ndi FEP, valavu ya gulugufe yokhala ndi teflon ndi valavu ya gulugufe wokhala ndi FEP nthawi zambiri amagwiritsidwa ntchito popanga zinthu zolimba zowononga.

 

Vavu ya gulugufe yokhala ndi fluorine ndi imodzi mwa zinthu zazikulu zomwe zimapangidwa ndi mavavu a ZFA. Magulu athu atatu ndi awa:

1. Malinga ndi kapangidwe ka thupi la valavu, lingagawidwe m'magulu awiriawiri.

2. Malinga ndi kapangidwe ka mkati, mkati mwake mungagawidwenso m'magulu awiri: valavu ya gulugufe yokhala ndi mzere wokwanira ndi theka. Vavu ya gulugufe yokhala ndi mzere wokwanira ndi thupi la valavu ndipo mbale ya valavu imakutidwa ndi rabara; theka la mkati limatanthauza kokha mkati mwa thupi la valavu.

3. Malinga ndi mtundu wake, ma valve a gulugufe okhala ndi Teflon akhoza kugawidwa m'magulu awiri:Mtundu wa valavu ya gulugufe yokhala ndi fluorine, valavu ya gulugufe ya fluorine yokhala ndi lug ndi valavu ya gulugufe ya fluorine yokhala ndi flange.

 

Ma valavu a gulugufe okhala ndi fluorine:

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

2. Valavu ya gulugufe yokhala ndi teflon, yoyenera kugwiritsa ntchito mankhwala oopsa komanso owononga kwambiri.

3. Pambuyo potseka mayeso oteteza mobwerezabwereza, valavu ya gulugufe yokhala ndi PTFE siiwononga chilengedwe.

4. Kapangidwe ka kapangidwe kogawanika kochotsedwa. (Ngati mukufuna)

5. Mlingo wa kutchinjiriza umagwirizana ndi malamulo a zida.

6. Ikhoza kukhazikitsidwa pamalo aliwonse; Yopanda kukonza ndipo imatha kukwaniritsa zofunikira pamikhalidwe yosiyanasiyana yovuta yogwirira ntchito.

7. Zochotsedwa, zinthu zitha kubwezeretsedwanso.

8. Zinthuzo zikugwirizana ndi miyezo ya FDA.

9. Kuchita bwino komanso kugwira ntchito bwino potseka.

10. Kapangidwe kake ndi kosavuta komanso kakang'ono, kokongola.

11. Zipangizo zotsekera sizimakalamba kapena dzimbiri, ndipo zimakhala ndi moyo wautali.
