How does the LQ-GXF High-temperature pressure relief valve cope with high temperature expansion problems through structural optimization?

1. Structural design optimization to reduce the impact of high temperature expansion
The LQ-GXF High-temperature pressure relief valve has made multiple optimizations in structural design to reduce the impact of high temperature expansion on the equipment. The valve adopts a new structural form of welding the centerline butterfly plate and the short structural steel plate. This design makes the overall structure of the valve more compact and lightweight, and can also ensure that the butterfly plate is evenly heated in a high temperature environment, avoiding deformation problems caused by local overheating. The design of the centerline butterfly plate enables heat to be evenly distributed on the entire butterfly plate, reducing the concentration of thermal stress and improving the thermal stability of the valve. The welding of the short structural steel plate enhances the overall rigidity of the valve, improves its structural stability in a high temperature environment, and avoids structural deformation and loose connection problems caused by high temperature expansion.

2. Material selection and sealing structure design
In terms of material selection, the LQ-GXF High-temperature pressure relief valve fully considers the requirements of high temperature environment. Key components such as the valve body and butterfly plate are made of high temperature resistant and low thermal expansion coefficient materials. These materials can maintain good dimensional stability and mechanical properties in a high temperature environment, avoiding structural deformation and sealing failure problems caused by high temperature expansion. The sealing structure of the valve is also specially designed to maintain good sealing performance in high temperature environments and prevent smoke leakage. This sealing structure can adapt to the changes in thermal expansion in high temperature environments, and can also ensure that the valve maintains a stable sealing effect during long-term operation, thereby improving the safety and reliability of the system.

3. Flexibility and reliability of installation and operation design
The installation and operation design of the LQ-GXF High-temperature pressure relief valve also fully considers the impact of high temperature expansion. The valve can be installed in multiple positions and is not affected by the flow direction of the medium. This enables the valve to adapt to different working conditions during installation and use, and avoid installation and operation problems caused by high temperature expansion. This flexible installation method improves the applicability of the valve and can also reduce the complexity of the installation and maintenance process. The valve is easy to operate. With compressed air as the power source, the valve stem drives the disc-shaped butterfly plate to rotate around the axis to control the flow. This operation method is simple and reliable, and can also avoid the impact of high temperature expansion on the operating mechanism, ensuring the normal operation of the valve in a high temperature environment. Compressed air, as a power source, can provide stable operating force, and can also avoid the impact of high temperature environment on the electric or hydraulic drive system, thereby improving the reliability and safety of the valve.
