The pneumatic black water control valve is developed by FISHERR Company of USA, which has made great contribution to the coal chemical industry. Qigao valve is mainly used for high pressure difference, strong erosion, strong corrosion, solid particles in the medium and the flow and pressure under flash evaporation condition. The control effectively solves the problem that the inner parts of the regulating valve are easy to be eroded. It has been widely used in many domestic coal chemical enterprises and has been praised by the users. Compared with the general control valve, the black water control valve has compact structure and smooth flow path, which can minimize the flow resistance and erosion; the valve stem surface is sprayed with cemented carbide to ensure the anti-erosion ability of the valve stem and the medium contact part; the lower guide pipe structure is used to guide and scrape the impurities adhering to the valve stem, which is effective. The valve head, seat and outlet runner are made of tungsten carbide material, which can effectively prevent the erosion of the medium. The spring type double-acting cylinder actuator has good rigidity, high output power and stable valve operation. The valve positioner is the original imported intelligent product with self-diagnosis. Function, adjustment is very simple; the valve seat is integral, valve head and stem (spare parts) connected as one, valve maintenance, spare parts replacement is simple; stem diameter is large, can effectively solve the vibration of the valve stem in flash operation. The results of laboratory tests and actual working conditions verify that the black water control valve is running well and its quality is in the leading position in the same industry in China.
Advanced technology
Black water control valve is one of the most important equipment in coal chemical plant. It has been used in gas, liquid and solid three-phase flow medium with large pressure difference between inlet and outlet for a long time. On the premise of ensuring regulation characteristics, both material selection and structural design reflect the designer's conception and measures of corrosion resistance, erosion resistance, safe and reliable operation. Unique fluid structure design, special technology, material formula and pneumatic actuator make the performance of the control valve more stable and reliable. Valve body material can be selected WCB, WC6-12, 304, 316L, dual phase steel, special materials and so on. The valve body can be forged or cast. This valve can replace foreign Blackwater and ash water regulating valve.
Structural characteristics
1. Fluid: the design process solves the vortex problem and ensures the smooth flow of fluid.
2, resonance sleeve: designing resonance sleeve effectively solves the resonance generated by high voltage differential.
3. Resonance sleeve technology: Resonance sleeve cavity designed a scraper, effectively scraping the surface of the valve core coke, anti-jamming function.
4, stem: anti whirlpool design, stem and spool by mechanical connection.
5. Spool and Seat: Spraying diamond on spool and seat effectively solves the severe problems such as flash evaporation, particle erosion and cavitation erosion.
6. Runner design: Hot-pressed inlaid and sprayed diamond was used in inlet and outlet runner and diameter-changing zone to solve the technical problems of erosion, flash evaporation, particle erosion, cavitation erosion and hard cracking of inlet and outlet runner.
7, maintenance: design structure maintenance, disassembly and assembly is simple.
Black water control valve is suitable for long-term use in gas, liquid and solid three-phase flow medium with large pressure difference, strong corrosion and serious erosion.
