The rubber-lined butterfly valve D341X-10C is a valve that adopts a rubber-lined sealing structure between the butterfly plate and the valve seat. The valve is opened and closed by the rotation of the valve stem. The main material is usually carbon steel or stainless steel, while the butterfly plate and sealing surface are covered with corrosion-resistant materials such as high-performance rubber or fluoroplastics. This design not only reduces the overall weight of the valve, but also significantly improves the valve’s corrosion resistance and sealing performance.

Aiming at the high-temperature environment of the thermal power station boiler system, the D341X-10C rubber-lined butterfly valve uses high-temperature-resistant rubber as the sealing material. For example, materials such as ethylene propylene rubber (EPDM) and polytetrafluoroethylene (PTFE) can maintain stable physical and chemical properties at higher temperatures, effectively resist material aging and deformation caused by high temperatures, and ensure the valve’s reliability under high temperature conditions. Sealing reliability.

The medium in the boiler system of a thermal power station often contains corrosive substances, such as sulfates, chlorides, etc., and is often accompanied by the erosion of solid particles. The D341X-10C rubber-lined butterfly valve uses corrosion-resistant rubber or fluoroplastic as the lining material, which effectively isolates the medium from corroding the valve body and internal parts. At the same time, the rubber layer on the surface of the butterfly plate can also absorb part of the impact energy, reduce direct wear of solid particles on the valve, and extend the service life of the valve.

Under the high flow rate conditions of boiler pipes, the scouring force of the medium on the valve increases, placing higher requirements on sealing performance. The D341X-10C rubber-lined butterfly valve optimizes the sealing structure and adopts a multi-layer soft stacked sealing ring or spherical sealing surface design to increase the contact area and sealing pressure of the sealing surface, effectively resisting the erosion and damage of the sealing surface by high-flow media. In addition, the valve is equipped with high-quality electric or pneumatic actuators to ensure that the valve can open and close quickly and accurately, further improving the sealing performance.

The medium composition and temperature in the boiler system of a thermal power station often change with changes in working conditions. The D341X-10C rubber-lined butterfly valve can adapt to a variety of media and temperature conditions by replacing the lining and sealing rings of different materials. For example, when the medium contains highly corrosive substances, fluoroplastics can be used as lining materials; when the medium temperature is high, high-temperature resistant rubber or fluoroplastics can be used as sealing materials. This flexibility allows the D341X-10C rubber-lined butterfly valve to be widely used in various complex working environments.

We can conclude that the D341X-10C rubber-lined butterfly valve plays an important role in the boiler system of thermal power stations with its excellent high temperature resistance, corrosion resistance and wear resistance, as well as good sealing performance under high flow rates and medium changes. effect. Through reasonable material selection, design and manufacturing technology, the D341X-10C rubber-lined butterfly valve not only improves the safety and stability of the system, but also reduces maintenance costs and operational risks.
