In the boiler system of thermal power station, the straight-through lift check valve H41H-100 is a key device to prevent medium backflow. Its design life and the wear resistance of key components are directly related to the safe and stable operation of the system. At the same time, the material selection of the valve is also an important factor to ensure its long-term adaptation to the complex medium and environment of the boiler system.

The H41H-100 straight-through lift check valve is designed and manufactured in accordance with the strict national standard GB/T12235 to ensure that the valve has good pressure bearing capacity and sealing performance under the nominal pressure PN100 (i.e. 10MPa). Its simple structural design, reliable operation and easy maintenance lay the foundation for the long-term and stable operation of the valve.

The key components of the valve, such as the valve disc and valve seat, are made of high-quality wear-resistant materials, which make it have excellent wear resistance, high temperature resistance, corrosion resistance and abrasion resistance, and can maintain a long-term stable sealing effect in high temperature, high pressure and corrosive media, thereby extending the design life of the valve.

The sealing pair of H41H-100 check valve is advanced and reasonable. Through precise processing and matching, the sealing surface between the valve disc and the valve seat is ensured to fit tightly, reducing medium leakage. At the same time, the wear-resistant design of the sealing surface also ensures that the valve is not easily damaged during frequent opening and closing, further improving the service life of the valve.

Analysis of wear resistance of key components

As key components of the check valve, the wear resistance of the valve disc and valve seat directly affects the overall life of the valve. The H41H-100 check valve uses high-hardness and high-wear-resistant materials to make the valve disc and valve seat, and through reasonable surfacing process and heat treatment technology, the wear resistance and abrasion resistance of the material are improved. In addition, the opening and closing movement of the valve disc is reasonably designed, which reduces direct friction with the valve seat and further extends the service life of key components.

In the boiler system of a thermal power station, the media are mostly high-temperature, high-pressure steam, water and some corrosive gases or liquids. The working environment is complex and changeable, including high temperature, high pressure, vibration and possible impact loads. The H41H-100 check valve has good adaptability and can maintain stable performance in these harsh environments. At the same time, through reasonable structural design and manufacturing process, the reliability and durability of the H41H-100 check valve made of WCB material in the boiler system can be further improved.

In summary, the H41H-100 straight-through lift check valve plays an important role in the boiler system of thermal power plants due to its excellent design life and wear resistance of key components. At the same time, WCB material has become one of the ideal choices for manufacturing this type of check valve due to its good mechanical properties, corrosion resistance and high temperature resistance.
