Mine Mine explosion-proof valve valve valve Jiangsu Lan

江苏兰 valve General Equipment Co., Ltd. products through a national certification explosion-proof electrical product quality supervision and inspection center, made explosion-proof certificate and coal safety certificate. Explosion-proof multi-turn electric actuator for opening and closing parts of linear motion valves, such as gate valves, diaphragm valves, piston valve, water valve and so on. For the valve open, close or adjust. Is the valve to realize remote control, centralized control of the essential drive and self-control. They have a full-featured, reliable performance, advanced control system, small size, light weight, ease of use and maintenance. Widely used in electric power, metallurgy, petroleum, chemical, paper, sewage treatment and other sectors. Protection Type: Outdoor for non-flammable, explosive and corrosive properties of the medium. Explosion-proof products dI and dIIBT4 two kinds, dI applicable to non-coal mining face; dIIBT4 used in factories, for environmental explosive gas mixtures IIA, IIB grade T1-T4 group was. 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; Jiangsu Lan valve General Equipment Co., Ltd. has sophisticated machining equipment and testing equipment, with a sound and effective quality management system. ZB flameproof electrical equipment work environment and main technical parameters 1 Power supply: Rated voltage: Three-phase 380 / 660V; Control voltage: 24V, 36V; rated frequency: 50Hz. 2 Operating System: short 10 minutes 3 Operating environment: 3.1 atmospheric pressure 80 ~ 110kPa; 3.2 Ambient temperature: -20 ~ + 40 ℃; 3.3 Relative humidity: ≤95% (+ 25 ℃ when); 3.4 for containing methane, coal dust explosive hazardous gases (excluding mining face); 3.5 protection: IP55
