rotary valves for materials such as lithium trichloride, sulfate, polymer particles, catalysts, disinfectant powders, trichloroisocyanuric acid, sodium dichloroisocyanurate, calcium hypochlorite, sodium hypochlorite, lime powder, and materials containing corrosive components such as chlorine and sulfur? Tongqi recommends materials such as titanium alloy, ceramic, tungsten carbide, PTFE, PTFE, 316L, etc. The core characteristics of PTFE lining for rotary valves are: extreme corrosion resistance, wide temperature applicability (-180 \u2103~260 \u2103), zero adhesion and anti blocking, soft seal and no leakage. It is specially used for discharging strong acids, strong alkalis, organic materials and viscous slurries at the bottom of reaction vessels\/storage tanks. \u200c\u200c\u3000\u3000Structure of PTFE lined sliding rod rotary valve:\u3000\u3000Size: DN200\u3000\u3000Main structure: 304 valve body; Material contact part: lined with PTFE and sprayed with ceramic rotor.\u3000\u3000Mainly used for transporting lithium battery cathode materials, lithium iron phosphate, ternary materials, chemical raw materials, pharmaceuticals, etc.\u3000\u3000Partial customer requirements:\u3000\u3000Lined PTFE star shaped feeding valve: media: AIBN, dichloroethane, sodium bicarbonate, potassium carbonate. DN150 speed: 24r\/min, feeding capacity 150Kg\/h, material: S30408 lined with PTFE, equipped with frequency converter speed regulation, equipped with frequency converter motor. Star feeder (DN200), volume: 8~10L\/rev, speed: 25~30r\/min, material: S30408 lined with PTFE, motor power: 1.5KW, star feeder variable frequency speed regulation, all electrical and instrumentation facilities need to consider gas and dust composite explosion-proof.\u3000\u3000Material: Powder, powder added to the coating, dry powder feeding rate [m \u00b3\/h] 0.3. Corrosive, size DN250. PTFE in contact with the material, shell 304.\u3000\u3000Features: Corrosion resistant, material bonding equipment, can be quickly cleaned and reset.\u3000\u3000Stability is superior to other detachable valves, and the rotor can be pulled out in place.\u3000\u3000Anti sticking and self-lubricating: The surface friction coefficient is extremely low, and the material is not easy to adhere and accumulate. It is particularly suitable for high viscosity, easy crystallization, or particle containing slurry discharge, to prevent blockage or corrosion under scale caused by “hanging materials”.\u3000\u3000Structural protection mechanism: The metal valve body provides compressive strength, and the PTFE lining isolates corrosive media, achieving the composite advantage of “steel load-bearing and fluorine anti-corrosion”. \u200c\u200c\u3000\u3000Super corrosion resistance: In addition to molten alkali metals and elemental fluorine, it can withstand concentrations of strong acids, strong bases, strong oxidants, and organic solvents, and isolate the medium from contact with the metal valve body.\u3000\u3000Star shaped unloader, 400 * 400 size, discharge capacity>35m \u00b3\/h, factory compressed air: 0.45-0.7MPa; There is some fertilizer dust, which has a certain degree of corrosiveness; Material: 304 lined with PTFE; Motor: The energy efficiency level meets the Level 2 energy efficiency standard of GB18613-2020.\u3000\u3000Corrosive particles are close to the powder, and are fed into the atmospheric pressure reaction kettle at room temperature of 30-40 degrees. The impeller should also be corrosion-resistant with small gaps. The material should be stainless steel lined with PTFE and resistant to organic solvents such as toluene, dichloroethane, and methyl acetate. All parts in contact with the material should be treated with PTFE. QJW, BZ feeding star shaped discharge valve 600-700Kg\/batch\/h, material S31603. lined with PTFE, DN250; XL feeding star shaped discharge valve 300-400Kg\/batch\/h, steel lined PTFE, DN200.\u3000\u3000Material properties: Chemical material, with a bulk density of 3.5 g\/cm3 to 4.5 g\/cm3. Flange connection, DN200. The parts in contact with the material are resistant to nitric acid corrosion. Sealing form: Adopting dual sealing of gas seal and oil seal.\u3000\u3000PTFE lined discharge valve, overcurrent medium: aluminum powder, conveying capacity of 20-30 kg\/h, installed under the top material bin of the reaction kettle, corroded by hydrochloric acid and water vapor inside the kettle, at room temperature and pressure, intermittent feeding. At present, ball valves and butterfly valves are not suitable. Aluminum powder is prone to sticking to the wall and getting stuck when exposed to water vapor. It needs to be replaced with a PTFE lined rotary feeder to prevent sticking.\u3000\u3000Our company specializes in the production of (B) GFY, YJD series air shut-off fans (air shut-off devices), star shaped unloaders, DS series electric air locks, DN type rotary valves, quick opening cleaning valves, anti jamming rotary valves, offset anti jamming, air delivery straight through rotary valves, high temperature and high pressure rotary valves, high temperature water-cooled, scraper self-cleaning, titanium alloy ceramic tungsten carbide PTFE PTFE nylon polyurethane, arch breaking machines, silo scraper crushers, fragmentation valves, screw conveyors and other products.
