Umgodi ongaphakathi kanye nendilinga yevalvu kagesi ene-fluorine-lined yenziwe ngenqubo yokubumba umjovo womfutho ophezulu, futhi ilayishwe nge-corrosion-resistant futhi ukumelana nokuguga.I-PTFE, ngakho anokwethenjelwa ukumelana nokugqwala nokusebenza kokuvala, futhi angasetshenziswa kahle emithonjeni eyonakalisayo eqinile njenge-asidi ne-alkali.

Ama-valve ane-fluorine-lined afanele ukuthuthwa koketshezi namagesi (kuhlanganise nomusi) ezinhlotsheni ezahlukene zamapayipi ezimboni, ikakhulukazi ukusetshenziswa kwemithombo yezindaba egqwala kakhulu, njenge: sulfuric acid, hydrofluoric acid, phosphoric acid, Cl₂, alkali eqinile, i-aqua regia nezinye imidiya ezonakalisa kakhulu.Isetshenziswa kabanzi ku-petroleum, amakhemikhali, ukudaya, isibulala-zinambuzane, i-asidi ne-alkali nezinye izimboni.Kuyisinqumo esifanele semishini yama-valve anti-corrosion.

Okulandelayo, ake ngethule izici nokusetshenziswa kwe-COVNA electric fluorine-lined wafer butterfly valve.

Izici

1. Ifaneleka njenge-valve yokulawula ukugeleza, enezici zokugeleza ezinembile.

2. Ifanele imidiya eqinile enezinto eziqinile.

3. Umthamo wokugeleza mkhulu, futhi isiqondiso sokugeleza se-medium asikhawulelwe.

4. Ukusebenza kahle kokuvala nokuvuza okuncane: Isihlalo sevalvu yokuvala senziwaI-PTFE, enokubekwa uphawu okuthembekile nokuzithambisa, futhi inokuvuza okuphansi.

5. Isakhiwo esilula nokugcinwa kalula

6. Ivalvu yovemvane ene-fluorine kagesi yamukela ipuleti levemvane eline-fluorine elicutshungulwe ngobuchwepheshe obuhle.Ipulasitiki ye-fluorine kanye ne-metal matrix kuhlanganiswe eduze ngaphandle kwezikhala, okuqeda ngempumelelo amabhamuza omoya we-interlayer futhi kuqede ukukhubazeka kwenqubo njengokubeka izingqimba nokuqhekeka.

7. I-radial seal yesihlalo sevalve uvemvane ene-wafer ene-wafer-lined fluorine ihlinzekwa ngephedi enwebekayo eqinisa amandla engu-360°, esebenzisa amandla okubuyisela i-radial futhi ilungise ngokuzenzakalelayo ukuwohloka ukuze kuqinisekiswe ngokuthembekile ukuthi akukho ukuvuza okumaphakathi ngaphansi kwesikhathi eside- ukusetshenziswa kwethemu.

8. Amahlombe e-shaft engenhla nangaphansi e-wafer kagesi ane-fluorine butterfly valve asebenzisa ukulayisha okunwebekayo kwezigaba eziningi ukuze kutholakale isinxephezelo esizenzakalelayo sokuvala, ukuze izindawo zokuvala zamashafu aphezulu naphansi angenzi igebe futhi aqinisekise ukuvuza okuphakathi.

Izinhlelo zokusebenza

·Uphethiloli

·Amakhemikhali

·Ukudaya

I-Acid ne-alkali

Uma ungumkhiqizi noma unjiniyela kulezi zimboni ezingenhla futhi unentshisekelo yokufunda okwengeziwe ngamavalvu ane-fluorine-lined, sicela.Xhumana nathiukuze uthole izixazululo ezengeziwe.
