DRG scotch yoke pneumatic actuators are fit for turn-off or metering control of 90 valves (suchas ball valves, butterfly valves and plug valves). lt can realize automatic control of industrial processwith various accessories. The principle is that compressed air enters the chamber to push the pistonto do linear motion, the piston's linear motion will be converted into the yoke's rotary motion bytransmission structures of the yoke pin and yoke groove, and drives the output shaft to rotate, thusachieving the control of the valve. DRG 系列撥叉式氣動執(zhí)行器有對稱式和傾斜式兩種類型,對應(yīng)兩種不同的扭矩輸出特性。對稱式的撥叉機構(gòu),具有更加平衡的扭矩曲線,主要適于球閥、旋塞閥的控制。 There are two types of DRG scotch yoke pneumatic actuators: symmetrical and inclined, whichcorrespond to two different torque output characteristics. The symmetrical yoke mechanism 我司生產(chǎn)的氣動執(zhí)行器廣泛應(yīng)用于石油和天然氣、化工、煉油、紙漿和造紙、水處理、電廠、煤化工等行業(yè)。 Our pneumatic actuators are widely used in petroleum and natural gas, chemical industry, oilrefining, pulp and paper making, water treatment, power plants and other industries. 工作介質(zhì)和壓力 Workinng Media and Pressure 工作介質(zhì)一般為干燥壓縮空氣、惰性氣體或抗磨液壓油 當(dāng)介質(zhì)為氣體時 氣缸工作壓力:3-10bar 最大使用壓力:10bar 推薦使用壓力:4-6bar 當(dāng)介質(zhì)為液體時請咨詢本公司 工作溫度及密封性能 Working Temperature and Sealing Performance 工作溫度 Operating temperatures: 標準-20℃-+80℃ Standard-20℃ to+80℃ 高溫-20℃-+150℃ Standard-20℃ to ±150℃ 低溫-40℃-+80℃ Low Temperature-40℃ to+80℃ 缸筒內(nèi)壁和活塞桿表面珩磨并鍍硬鉻處理,結(jié)合0 形圈的動態(tài)密封設(shè)計,大大提高產(chǎn)品的密封性能。 The cylinder inner wall and piston rod surfacehoning and hard chrome plating, combined withthe dynamic sealing design of O-ring, greatly im-prove the sealing performance of the product. 行程及調(diào)節(jié)范圍 Stroke and Adjusting Range 標準行程0-90°,兩個極限位置獨立的調(diào)節(jié)螺栓可方便進行±6°調(diào)節(jié);可為用戶定制0-60°等非標行程。 Standard stroke 0-90°,two indepent adjustment bolts at the extreme positions can facilitate adjust from-6°to±6°.Non-standard stroke is available,such as 0-60°,etc. |
