Jiangsu Lan valve General Equipment Co., Ltd. to improve customer service system, and we "do everything for the user satisfaction" commitment. Valve actuators counter also called stroke control mechanism: the decimal gear, ram, cam and micro switch composition, referred to as the counter. It works by decelerating box a pinion (Z = 8) led the counter works, if the counter press valve open or closed position has been adjusted, when the counter with the output shaft to the pre-adjusted position (the number of turns time), the cam is rotated 90 o. Oppression micro switch operation, cut off the power supply, the motor stops, the trip has been achieved on the electric system (number of turns) controlled. To control the large number of turns of the valve, the gear ratio of the transmission, adjustable cam turn 180 o or 270 o re oppression micro switch operation.江苏兰 valve General Equipment Co., Ltd. is a professional research and development, production and sales of valve actuators tech enterprises, products through major role in the national certification explosion-proof electrical products for Quality Supervision and Inspection Center, gearing, made explosion-proof certification. Accessories spring valve actuators capable of storing energy is a part, can be used to shock absorption, grip, storage and measurement compression springs torsion springs tension springs flat scroll spring buffer, gearing English, the use of deformation energy conversion, Force and deformation, fasteners, such as nuts the spring washers. Made of high-quality steel, alloy steel, carbon steel cable. Jiangsu Lan valve General Equipment Co., part of the overall type rotary valve electrical devices, referred to as Q-type electrical equipment. The valve and turn it on, turn off or adjust the drive control device for butterfly valves, ball valves, plug valves and dampers, and so do 90 ° rotation of the valve. Adjustment module can receive and output 4 ~ 20ma standard signal. Electrical components mounted on a board can be flipped in order to torque control, motion controller, the degree of opening adjustment mechanism. There are three buttons on the button box, in the middle of the local / remote switching button, which left the scene off valve button to the right of the field to open the valve buttons, cover button box for the remote control to open the lid for on-site operations. Stroke control mechanism, decimal counter principle, control and high accuracy. For the full range of general member, its structure, transmission, its working principle is: by the reducer inside a pair of size bevel gear drive pinion (Z = 8), and then driven counter. If the counter by the valve open and closed positions are adjusted, when the counter with the output shaft to advance the adjusted position (laps), then the cam is rotated 90 °, forcing the micro switch operation, cut off electrical power, the motor stopped, in order to achieve electrical devices stroke (number of turns) controlled.
