Jiangsu Lan valve General Equipment Co., Ltd. of QMB part of the rotary valve small flameproof electrical equipment, conditions of use for coal specially designed and manufactured. For coal fire protection, dust, Central Pump House Underground jet pump and vacuum pump package. QMB type valve actuators, small size, light weight electric blue valve controller can interface with the DCS system controller electric plant, in order to achieve automatic control. Deceleration mechanism: QMB3.5 / 5 is a multi-stage spur gear reducer; QM9 / ??15/25 by gear and small teeth difference planetary gear reducer drive consisting of two stages; the power of the motor is transmitted to the output tray by the deceleration mechanism. Jiangsu Lan valve General Equipment Co. produced a series QMB type flameproof electric valve actuators Model Specifications: QMB3.5-1.25G QMB5-1.25G QMB9-0.85G QMB15-0.6G QMB25-0.6G torque control mechanism: When the output torque increases to the setting torque, the torque shaft angular displacement generates electric controller accessories, action triggers the Hall element, thereby cutting off power to the motor, the motor is stopped, in order to achieve the electric actuator output torque control, to achieve torque protection purposes.
