Mine Mine valve valve valve Jiangsu Lan

Jiangsu Lan valve General Equipment Co., Ltd. research and development, production and marketing of ZB explosion-proof multi-turn electric actuator for opening and closing the valve element linear motion, such as gate valves, diaphragm valves, piston valve, water valve and so on. ZB series explosion proof electric apparatus aspect of the present series of explosion-proof electric apparatus, the main body and the connection box. Junction box cable into the device is suitable for the rubber cable wiring structure, explosion-proof junction box wiring plate built, splice tray to a ground terminal is provided inside; junction box has four outlet ports, power, and control lines can be introduced by different cable separately means the introduction of mouth.江苏兰 valve General Equipment Co., Ltd., a coal mine gas pumps and automation needed for a dedicated drainage valve configured ZB series of mine explosion-proof structure means points flameproof electric valve: This series of electric devices require explosive gas mixture inside the product Explosion , the flameproof enclosure shall not be damaged or explosive mixture outside the explosion electrical device, for which:. a component parts such as flameproof enclosure box, cover, junction box cover, junction box housing, etc., subject to 1.0 after finishing MPa, which lasted no less than 10S hydrostatic test pass. b. Internal length flameproof joint clearance, surface roughness and the junction box between bare conductors, bare metal conductor clearances and creepage distances between product design should be consistent with the requirements. c. bolted flameproof enclosure are equipped with spring washers to prevent self-loosening. d. electrical equipment box, cover, stroke bush, torque bushings, junction box housing, junction box cover are made of gray cast iron HT250. e. box, cover, stroke bush, torque bushings, junction box housing, junction box cover, splice tray, explosion connected sets, seals flameproof components. f seals made of NBR XH-50, 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.
