THE PEOPLE’S REPUBLIC OF CHINA 一、 一、 概述概述 General Description 首先感谢您选用我厂生产的 QB 系列阀门电动装置及其它产品我厂是机械工业部定点 制造各种阀门电动装置及其专用电机的厂家，于 1995 年通过 ISO9001 质量认证QB 系列产 品是我厂广泛地吸取国内外阀门控制的先进经验而设计的新一代产品具有结构紧凑、性 能可靠、调整方便等特点性能指标达到 JB/T8528-1997 标准该系列产品用于阀瓣做部 分回转的阀门，如球阀、蝶阀、风门等，是对阀门实现远控、集控和自控的必不可少的驱 动装置，是工业管道系列控制中的重要单元，广泛应用于电站、石油、化工、冶金等行业。

First and foremost, thank you for your choice of our QB Series electric valve actuators and other products. Our works is appointed by the Machine Building Industry Ministry to manufacture various electric valve actuators and their special purpose motors and our quality system was certified to conform to ISO 9001 in 1995. QB series products are a new generation developed by us. Adopting advanced valve control technology at home and abroad, these products are of compact structure, reliable performance and easy adjustment. The performance index is conformed to Std JB/T8528- 1997. This series is applicable to part- turn valves, such as ball valves, butterfly valves and dampers and is necessary drive device to carry out local control, centralized control and automatic control of valves, and so it is an important unit for industry pipe- line control system and is adopted extensively in power station, oil industry, chemical industry, metallurgical industry and so on. 二、型号表示方法二、型号表示方法 Type Representation QB Protection: “W” means outdoor type 防护： “W”为户外型 Output speed: r/min 输出转速：r/min Nominal torque of output shaft 10N·m 额定转矩 10N·m Q mans part- turn actuator, suitable to ball valve, buttery valve etc. B means products of second generation Q 表示部分回转型阀门电动装置，适用于球阀、蝶阀等。

B 表示第二代产品 例：QB50- 1W 表示第二代部分回转电装产品，输出额定转矩 50N·m,输出转速 1r/min, 户外型 Example: QB50- 1W means part- turn actuators of second generation, output torque 500N · m, output speed 1 r/min, outdoor type. 三 工作环境和主要技术数据 三 工作环境和主要技术数据 Service Environment and Main Technical Data 1. 电机电压：380V，50Hz（特殊订货可 380V～660V,50Hz,60Hz） 控制电压：220V, 50Hz（特殊订货可 220V～240V,50Hz,60Hz） Power voltage: 380V,50Hz(380V～660V,50Hz,60Hz for special order) Control voltage: 220V,50Hz(220V～240V,50Hz,60Hz for special order) 2. 工作环境：Service environment: 2.1 环境温度：-20～60℃ Environmental temperature: -20～60℃ 2.2 环境相对湿度：≤90%（25℃时） Permitted relative humidity no more than 90%（25℃） 2.3 工作环境不含有腐蚀性、易燃、易爆的介质； No corrosive, flammable and explosive media. 2.4 防护等级 IP55（特殊订货可达 IP68） Protection IP55 （IP68 for special order） 3. 短时工作制，时间定额为 10 分钟； Short- time duty, rated time 10 minutes. 4. 规格和主要技术数据见表 1。

Reducer: two pairs of spur gears and a pair of worm and wormwheel. Travel mechanism: cam mechanism simultaneous with output shaft. Torque mechanism: expelled worm shaft makes crank and rocker press microswitch to generate signal. Position indicator: indicating valve position locally and transmitting the signal of valve opening degree.(a potentiometer for remote control is mounted at the flank of output shaft) Hand/electric operation clutch: semi- auto exchange mechanism. Before hand operation, it must be declutched and it will turn back automatically while electric operating, do not turn it back by hand. 电机 Motor 转速 Output speed 1r/min 2r/min 型号 Type 功率 Power kW 电流 Current A 额定转矩 Rated torque (N·m) 最大控制 转矩 Max control torque N·m 最小控制 转矩 Min Control torque N·m 阀杆直径 Dia of stem mm 速比 Ratio 重量 Weight kg 0.03 0.25 125 0.05 0.45 125 >125 62.5 22 0.05 0.45 250 QB12.5 25 0.09 0.63 250 >250 125 28 63 30 0.09 0.63 500 0.18 1.0 500 >500 250 42 0.18 1.0 1000 QB50 100 0.25 1.4 1000 >1000 500 50 47 50 0.25 1.4 2000 0.55 2.4 2000 >2000 1000 60 0.37 1.8 3000 >3000 1500 60 QB200 400 0.55 2.4 4000 >4000 2000 80 53 95 图 1 QB 型结构图 Fig.1 constructions of type QB 五、外形及连接尺寸 五、外形及连接尺寸 Contour and Connection Dimensions 外形尺寸见图 2 和表 3，连接尺寸见图 3 和表 2。
