Introduction to the sealing surface structure of high temperature and high pressure American standard globe valve

   The high temperature and high pressure American standard globe valve is very important in the industrial production process. While bringing efficiency to the pipeline, it also guarantees the safety of the operators. Therefore, the structure, performance parameters and reliability of high temperature and high pressure American standard globe valves have attracted more and more attention from some enterprises and manufacturers. The following editor will talk about the sealing surface structure of the high temperature and high pressure American standard globe valve, hoping to bring you some help in this regard.

    The sealing surface of the high temperature and high pressure American standard globe valve is composed of two copper rings, one is fixed on the valve core and called the moving ring, and the other ring is fixed on the valve body and called the static ring. When the shut-off valve is closed, the two rings fit together to form a seal, dividing the liquid in the valve body into two unconnected parts.

    The use of a copper ring as the sealing surface takes advantage of the chemical stability of copper and the softness of texture. Because copper is chemically inactive, long-term use in neutral liquids such as water and steam is not prone to chemical changes, deterioration and corrosion, and can guarantee the sealing effect for a long time. At the same time, due to the soft texture of copper, even if the end face is impacted by the high-pressure liquid in the pipeline during long-term use, and even the occasional impact of debris causes a slight deformation of the ring end face, it has to withstand a relatively large amount when closing the high temperature and high pressure American standard globe valve. External force can usually make the sealing surface seal well without affecting the use effect, so it is very suitable for making sealing surface materials.
