1. Structural design
The structural design of the cone seal high-pressure ball valve is the basis of its excellent performance. As the core component, the valve body is cast or forged with high-strength and corrosion-resistant materials to ensure stability and durability under high-pressure environments. The ball is the key to achieving fluid control, and its surface is precisely machined and polished to ensure a perfect fit with the cone seal seat. As the core of the sealing system, the cone seal seat uses advanced sealing materials and designs to form a reliable seal under high pressure to prevent fluid leakage. In addition, the design of the valve stem also fully considers strength and sealing. Through precise threaded connections and sealing devices, it ensures that the valve stem will not leak fluid during rotation. At the same time, the valve connection method adopts threaded connection, which is easy to install and disassemble, and is suitable for various high-pressure pipeline systems with internal and external threads.

2. Working principle
The working principle of the cone seal high-pressure ball valve is based on the rotation of the ball to control the on-off of the fluid. When the valve stem rotates to the open position, the through hole on the ball is aligned with the center through hole of the valve body, forming a smooth fluid channel, allowing the fluid to pass freely. At this time, a certain gap is maintained between the cone seal seat and the ball to reduce the scouring and wear of the sealing surface by the fluid. When the valve stem rotates to the closed position, the ball gradually rotates to close contact with the cone seal seat, and through the extrusion of the cone surface and the elastic deformation of the sealing material, a solid sealing barrier is formed to prevent the fluid from passing through the valve. This sealing method can not only effectively resist the impact of high-pressure fluid, but also maintain stable sealing performance under harsh working conditions such as temperature changes and medium corrosion.

3. Special considerations
The design and material selection of cone-sealed high-pressure ball valves working in high-pressure environments must fully consider the impact of high pressure on the valve. Key components such as the valve body and the ball must be made of high-strength and high-toughness materials to withstand high-pressure impact without deformation or rupture. At the same time, the sealing system must also use advanced sealing materials and designs to ensure that good sealing performance can be maintained under high pressure. In addition, the cone-sealed high-pressure ball valve working in a high-temperature environment must also consider the high-temperature resistance of the material to prevent sealing failure due to softening or deformation of the material. For valves working in corrosive media, materials with excellent corrosion resistance must be selected to extend the service life of the valve and reduce maintenance costs. These special considerations together constitute an important guarantee for the stable operation of the cone-seal high-pressure ball valve under complex working conditions.
