Valves, Jiangsu Lan valve map, valve Legend

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, 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. 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, adjustable cam turn 180 o or 270 o re oppression micro switch operation. Jiangsu Lan valve General Equipment Co., Ltd. of valve actuators are programmed to achieve the valve, automation, and remote indispensable integral drive unit: The control system and electrical devices called the whole collection in one electric device, the electrical part by the integral module, button box, opening of the table (or digital indicator), contactors and other components, shown in Figure 6. Electrical components mounted on a board can be flipped in order to torque control mechanism, stroke control mechanism, opening indication mechanism to adjust. There are three buttons on the button box, in the middle of the local / remote switching button, which left for the site off valve button to the right of the field to open the valve buttons, cover buttons cover the remote control, remote control switch contacts to 24VDC (24VDC already within supplied), open the lid of field operations
