Ash discharge ball valve has same features of coal injection ball valve, is an ideal equipment for controlling dust-containing gas, granular containing liquid and powder. It is mainly suitable for dust removal and ash removal system of blast furnace. It is widely used in the pipeline of petroleum, chemical industry, power generation, papermaking, thermal power plant, etc., for cutting off or connecting media. Suitable media are: water, steam, oil, nitric acid, acetic acid, urea and other corrosive and strongly oxidizing media
Working principle of ash discharge ball valve is to open or close the valve by rotary valve. Pneumatic ball valve is light switching, small volume, can be made into a very large diameter, reliable sealing, simple structure, convenient maintenance, sealing surface and spherical surface often in the closed state, not easy to be eroded by the media and widely used in various industries. Ash discharge ball valve adopts floating structure, the ball is precision cast piece, externally hard chromium plating treated, valve seat adopts metal or reinforced polytetrafluoroethylene material, the media flowing orifice is the same as the pipe diameter, flow capacity is great, flow resistance is very small, and there is no leakage when closed, generally used as open/close valves, especially for high viscosity, fiber or granular contained media.
1. Long service life, sealing ring adopts self-lubricating PTFE. Valve ball and sealing ring of ash discharge ball valve has micro friction, which effectively improve the service life.
2. Small size, light weight, easy to install and maintain.
3. Ash discharge ball valve can be installed in any direction and any part of the pipelines.
4. Connecting valve axial packing of ash discharge ball valve reach up to the anti-corrosion A class sealing, working temperature of -28 ℃ to 300 ℃ , operating mode: Manual, pneumatic, electric, hydraulic and electro-hydraulic, etc.
