Blackwater pneumatic control valve

Pneumatic black water regulating valveFISHERR USAThe company has made significant contributions to the coal chemical industry by leveraging its technological advantages. Jiatai Valve has been developed based on the principle of regulating valves using the expertise of high-end personnel for many years. It is mainly used for flow and pressure control under high pressure difference, strong flushing, strong corrosion, medium containing solid particles, and flash evaporation conditions, effectively solving the problem of easy erosion of regulating valve components. It has been widely used in many domestic coal chemical enterprises and has received unanimous praise from users. Compared with general regulating valves,Black water regulating valveCompact structure, smooth flow path, can minimize flow resistance and erosion to the greatest extent possible; The surface of the valve stem is sprayed with hard alloy to ensure the erosion resistance of the contact part between the valve stem and the medium; Adopting a bottom guide tube structure, it plays a role in guiding and scraping off impurities adhered to the valve stem, effectively preventing silicon deposition in the packing chamber; The valve head, valve seat, and outlet channel are all made of tungsten carbide material, which can effectively prevent erosion of the medium; Adopting a spring type double acting cylinder actuator, it has good rigidity, high output power, and stable valve operation; The valve positioner is an imported intelligent product with self diagnostic function and easy adjustment; The valve seat is integral, and the valve head and stem (spare parts) are connected as one, making valve maintenance and spare parts replacement easy; The larger diameter of the valve stem can effectively solve the problem of valve stem vibration during flash evaporation conditions. Through laboratory tests and actual working condition assessments, it has been verified that the black water regulating valve operates well and its quality is at a leading level in the domestic industry.

Black water regulating valveIt is one of the essential equipment in coal chemical plants, and this valve 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, duplex 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.

Two structural features:

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 of three products

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.
