Jiangsu Bell Mining Coal Safety Series Products
The ZB mining series explosion-proof multi turn valve electric device is easy to assemble with the valve for automatic control and is suitable for controlling the opening of the valve close. On site control or remote switch control, regulating control, bus control, etc. are essential driving devices for valve and air door centralized control and automatic control. This product has excellent features such as comprehensive functions, advanced control system, reliable performance, convenient use and maintenance, small size, etc. It has been widely praised and applied in coal mine, chemical industry, petrochemical, power, steel, metallurgy, water treatment, paper making and other industries. Suitable for use with gate valves, globe valves, throttle valves, diaphragm valves, water gates or turbine butterfly valves, turbine ball valves, turbine dampers and other valves.
The ZB series valve electric device is divided into: mining switch explosion-proof type, mining integrated explosion-proof type, mining and intrinsic safety integrated explosion-proof type, mining bus explosion-proof type, etc. according to the control mode. According to the connection method, it can be divided into torque type and thrust type.
There are two types of explosion-proof products, d1 and dIIBT4. d1 is suitable for non mining working faces in coal mines; DIBT4 is used in factories and is suitable for explosive gas mixtures of Class IIA, IIB, T1 to T4 environments. (See GB3836.1 for details). Explosion proof enclosures are used to separate the circuit parts that may be affected by sparks or arcs from the explosive gas mixture outside the enclosure, thereby achieving explosion-proof.
If this product is classified as explosion-proof, it complies with the relevant provisions of GB3836.1-2010 "Explosive Atmosphere Part 1: General Requirements for Equipment" and GB3836.2-2010 "Explosive Atmosphere Part 2: Equipment Protected by Explosion proof Enclosures". In terms of electrical performance, it complies with JB/T8529-1997 "Technical Conditions for Explosion proof Valve Electric Devices" and GB/T24922-2010 "Technical Conditions for Explosion proof Valve Electric Devices", and has been verified by the National Explosion proof Electrical Product Quality Supervision and Inspection Testing Center, obtaining a full series of explosion-proof certificates. It can be widely used in pipeline valve control systems in coal mines and underground.
