Jiangsu Lan Mine valve valve valve Figure Mine

Jiangsu Lan valve General Equipment Co., Ltd. has always been committed to the "leading technology, quality and efficiency, customer first, the undersigned about compliance" business philosophy. To improve customer service system, and we "do everything for the user satisfaction" commitment. Mine explosion-proof multi-turn valve actuators torque control mechanism: When the output shaft torque is subject to certain post, in addition to the rotation of the worm things, axial displacement, the crank drive, the crank drive bracket hit the block by angular displacement; when torque output shaft torque increases to the setting, then stent displacement amount so that the torque generated by the switching operation, thereby cutting off the motor power, motor stops. In order to achieve the electric actuator output torque control, electric valve to protect the goal.江苏兰 valve General Equipment Co. mine electric valve actuators compact structure, reasonable design, the valve rigid; no installation required direction, bi-directional sealing, flow resistance, long life; safe and reliable; for explosive methane gas Mine wells. Flameproof electric valve actuators main characteristics and uses of coal mine explosion-proof electric valve actuators for opening and closing the valve element linear motion, such as gate valves, globe valves, diaphragm valves, water valves and the like. After the increase in second-line deceleration devices can be used for butterfly valves, throttle duct valve. It is to achieve the valve open, close, adjust, remote control, centralized control of the essential drive. Jiangsu Lan valve General Equipment Co., Ltd. of valve actuators are programmed to achieve the valve, automation, and remote indispensable drives. Electrical wiring 1 drop cable used by the power line must be grounded, and contact with the ground terminal wiring plate. The introduction of cable minimum outer diameter Figure 10 and Table 4. Take a good line should be installed gaskets, seals, pressing with a compression nut. Shore hardness seals should be 45 to 55 degrees, the rubber seals of aging deterioration should be timely with the same structure, the same size, the replacement of the same material. See Figure 10. 2 unused cable entry port closure by blocking rod. 3 Electrical equipment should, external to reliable four-terminal connection: Conductor Crimping tool head is pressed against the wire, the wire can not bare; the terminals should be tightened, not loose; meet clearances and creepage distances shall comply with GB3836.3 -2010 requirements;
