Jiangsu Lan valve General Equipment Co., part of the overall type rotary valve actuators, referred to as Q-type electrical equipment. The valve to achieve open, closed, or adjusting 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 opening degree of institutional adjustment. There are three buttons on the button box, in the middle of the field / remote control switching button, which left the scene off valve button to the right of the field to open the valve button electric valve device, covered button box for remote control electric valves tender, open the lid of the field operations. Stroke control mechanism, using decimal counter principle, control and high accuracy. For the full range of common components, its structure, its working principle is: the deceleration box the size of a bevel gear drive pinion (Z = 8), and then drive counter. If the counter by the valve opening and closing positions have been adjusted electric valve material, when the counter with the output shaft to advance the adjusted position (laps), then the cam will rotate 90 °, forcing the micro switch operation, cut off electrical power , the motor stops, in order to achieve electrical devices stroke (revolutions) control. General Equipment Co., Ltd. Jiangsu Lan valve valve electric device is programmed to achieve the valve, automation and remote control equipment indispensable driving overall type: control system and electrical devices called the whole collection in one electric device, the electrical part is mainly composed of the overall type module, button box, the opening degree of the table (or digital indicator), contacts and other components, shown in Figure 6. Electrical components mounted on a board can be flipped, in order for the torque control means, the stroke control means to adjust the degree of opening indicating mechanism. There are three buttons on the button box, in the middle of the field / remote control switching button, the button on the left side of the field off valve, the right button to open the valve for the scene, covered with lid for the remote control button on the remote control switch contacts for 24VDC (24VDC been within available), open the lid for on-site operation of electric valves, electric valves, valve provided by 江苏兰 江苏兰 valve General Equipment Co., Ltd ..江苏兰 valve General Equipment Co., Ltd. (www.lanfa.cn) strong, credible, in Changzhou, Jiangsu regulating valve industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Jiangsu Lan valve and you hand into the brilliant, for a better future!
