As a high-performance industrial valve, trunnion ball valves are widely used in high-pressure and high-temperature working conditions in industries such as petroleum, natural gas, and chemical engineering. However, due to the complexity of its working environment, the stability of trunnion ball valves faces many challenges. To ensure its reliable operation in harsh working conditions, a series of measures must be taken to improve its stability.
Optimize structural design.
Connection between valve body and trunnion.
The stability of trunnion ball valves first depends on the firm connection between the valve body and the trunnion. Adopting high-strength welding processes and precise processing technologies to ensure the connection strength and precision between the trunnion and the valve body. By optimizing the structural design of the trunnion and increasing its load-bearing capacity and bending resistance, deformation and wear of the trunnion under high-pressure conditions can be effectively reduced.
Valve seat support structure.
The design of the valve seat support ring is crucial for the stability of
. Studies have shown that stress concentration at the contact position between the valve seat support ring and the valve seat sealing ring is one of the main reasons for sealing failure. By increasing the thickness of the support ring and optimizing its shape, stress can be effectively dispersed and stress concentration phenomena can be reduced. In addition, using high-strength materials to manufacture the valve seat support ring can further improve its deformation resistance.
Sealing structure.
Sealing performance directly affects the stability of
. Adopting a double piston effect (DPE) valve seat design can automatically adjust the sealing force under the action of medium pressure to ensure the reliability of sealing performance. At the same time, optimizing the material and shape of the sealing ring, such as using high-performance materials such as hydrogenated nitrile rubber (HNBR) and increasing the thickness of the sealing ring, can improve its wear resistance and corrosion resistance.
