Fluoroplastic lined corrosion-resistant butterfly valveet say pangiyan na polytetrafluoroethylene resin (odino profile processed) ed loob na dingding na steel odino iron butterfly valve pressure-bearing parts odino diad paway na tapew na butterfly valve inner parts diad panamegley na molding (odino inlay) a paraan. Say nikadkaduman kablian na butterfly valves sumpad mabiskeg ya makaderal iran media et ginawa ed nanduruman klase na butterfly valves tan pressure vessels.
Diad saray materyales ya anti-corrosion, say PTFE et walaan na agnaparaan ya ekselentin performance. Nilikud ed tinunaw ya metal, elemental fluorine tan aromatic hydrocarbons, nayarin usaren iya ed nanduruman konsentrasyon na hydrochloric acid, sulfuric acid, nitric acid, aqua regia, organic acid, mabiskeg ya oxidant, concentrated, alternating dilute acid, alternating alkali tan nanduruman organic agents et random ya reaksion. Say pangi-lining na PTFE ed loob na dingding na butterfly valve et aglabat makatalona ed saray kakulangan na abeban biskeg na materyales ya PTFE, no ag ingen makaresolbe met ed problema na resistensya na corrosion na saray materyales ya walay tema na butterfly valve. Makapuy so performance tan atagey so gastos. Niarum ni, nilikud ed ekselentin chemical stability to, say PTFE et walaan na maong ya antifouling tan anti-stick properties, alablabas ya melag ya dynamic tan static friction coefficients, tan maong ya anti-friction tan lubrication performance. Saya so uusaren bilang sealing pair parad pangilukas tan pangisara na saray butterfly valves, tan kaukolan ya nabawasan so sealing surface. Say panlalaban na saray butterfly valve et nayarin nabawasan, say operating torque na butterfly valve et nayarin nabawasan, tan say serbisyo na produkto et nayarin napaaligwas.
Fluorine-lined butterfly valve, ya kabkabat met bilang anti-corrosion butterfly valve, et mabetbet ya uusaren ed mairap iran kondisyon na pantratrabaho, balanglan makasamal tan makaderal iran kemikal, odino makaderal a tuloy ed nanduruman klase na acid-base odino organic solvents. Say agsuston pangusar et manresulta ed baleg ya lugi ed ekonomya tan graben resulta na. Say suston pangusar tan panmintina ed butterfly valve et makapanparukey na bilay na fluorine-lined butterfly valve, kanian anto ran detalye so nagawaan pian epektibon naprotektaan itan?
1. Antis ya usaren, basaen a maong so instruction manual na fluorine-lined butterfly valve.
2. Usaren iya ed loob na pressure, temperatura tan medium ya akasulat ed nameplate odino diad manual.
3. No uusaren, amperen so fluorine-lined butterfly valve ya mamawala na alablabas ya stress ed tubo lapud panguuman na temperatura, palemewen so panguuman na temperatura, tan mangiyan na U-shaped expansion joints antis tan kayari na butterfly valve.
4. Bawal so mangusar na lever pian lukasan tan isara so fluorine-lined butterfly valve. Imanoen ya obserbaan so posisyon na indikasyon na panlukas tan pansara tan say limit device na fluorine-lined butterfly valve. Kayari na pangilukas tan pangisara, ag mo pipiliten ya isara so balbula, pian napaliisan so masakbay a pakaderal na fluorine plastic sealing surface.
5. Parad arum ya media ya ag-establi tan mainomay ya nabulok (alimbawa, say pakabulok na arum ya media et pansengegan na idakel na volume tan pansengegan na abnormal ya idarakel na pressure ed kondisyon na pantratrabaho), ya pansengegan na pakaderal o itagas na butterfly valve, nepeg ya gawaen iray paraan pian naekal o nalimitaan iray sengegan na pakabulok na ag-establin media. . No manpipili na butterfly valve, say fluorine-lined butterfly valve ya walay automatic pressure relief device to et nepeg ya pilien base ed posiblin pananguman ed kondisyon na pantratrabaho lapud ag-establi tan mainomay ya nabulok na medium.
6. Paradsay fluorine-lined butterfly valvediad tubo ya walay makasamal, mainomay ya napoolan, makapasabog tan mabiskeg ya makaderal a medium, malet ya sebel ya isalet so packing no walay pressure. Anggaman say fluorine-lined butterfly valve et walay upper sealing function to ed desinyo, ag nirekomenda ya salatan so packing no walay pressure.
7. Parad saray tubo ya walay spontaneous combustion medium, nepeg ya gawaen iray kundang pian naseguro ya say temperatura na kaliberliber tan say temperatura na kondisyon na pantratrabaho et ag onlampas ed spontaneous combustion point na medium pian naprebentaan so peligro ya pansengegan na sinag na agew odino apoy ed paway.
Nausar ya medium: nanduruman konsentrasyon na acid-base salts tan pigaran organic solvents.
