Black water angle regulating valve

Black water regulating valve is one of the essential and important equipment in coal chemical plants,which has been used for a long time in gas,liquid,and solid three-phase flow media with large inlet and outlet pressure differences.Under the premise of ensuring the regulating characteristics,both material selection and structural design reflect the designer's concept and measures for valve requirements of corrosion resistance,erosion resistance,and safe and reliable operation.The unique fluid structure design,selection of special processes,material formulations,and pneumatic actuators make the performance of the black water grey water regulating valve more stable and reliable.The valve body material can be selected from WCB WC6-12、304、316L、Dual phase steel,special materials,etc.The valve body can be forged or cast.This valve can completely replace foreign black water and grey water regulating valves.

1. Pressure level: Class150~Class2500;
2. Caliber: NPS1 "~NPS28";
3. Sealing grade: ANSI B16.104 VI leak free grade;
4. Explosion proof grade: ExdIICT4, ExiaICIT4;
5. Flow characteristics: straight line, equal percentage (logarithmic) parabola, and fast opening, etc;
6. Transmission methods: pneumatic, electric, etc;
7. Connection methods: flange, welding, clamp, thread, etc. The flange standard is designed according to international, American and user requirements, and the external dimensions are customized according to the working conditions and user requirements.

Structural characteristics

1 Fluid: The design process solves the vortex problem and ensures smooth fluid flow.
2. Resonance sleeve: The design of the resonance sleeve effectively solves the resonance caused by high voltage difference.
3. Resonance sleeve process: A scraper is designed in the inner cavity of the resonance sleeve to effectively remove the coking on the surface of the valve core and Prevent jamming.
4. Valve stem: anti vortex design, with mechanical connection between the valve stem and valve core.
5. Valve core and valve seat: The valve core and valve seat are coated with diamond, effectively solving harsh problems such as flash evaporation, particle erosion, and cavitation.
6 channel design: The inlet and outlet channels, as well as the variable diameter area, use hot pressed inlaid spray diamond to solve technical problems such as erosion, flash evaporation, particle erosion, cavitation, and hard cracking in the inlet and outlet channels.
7 Maintenance: The design structure is easy to maintain and disassemble.
Scope of application
Black water regulating valves are suitable for long-term use in gas, liquid, and solid three-phase flow media with large pressure differentials, strong corrosion, and severe erosion.
