Impact-resistant high-temperature high-pressure valve body
ActiveCN224315583Ureduce shockExtended service lifeLift valveValve housingsSafe operationSliding contact
This utility model relates to the field of valve body technology, and in particular to an impact-resistant high-temperature and high-pressure valve body, comprising a valve body and an impact-resistant plate. The inner wall of the valve body has an inlet chamber and a drain chamber, which are connected. A limiting groove is formed in the inner wall of the inlet chamber, and the impact-resistant plate abuts against the limiting groove, with its outer peripheral wall in sliding contact with the inner wall of the limiting groove. Multiple flow holes are formed on the outer wall of the impact-resistant plate, with the diameter of the flow holes increasing from the middle to both ends. In this utility model, by setting up the impact-resistant plate, the impact force of the fluid is transferred from the inner wall of the valve body to the impact-resistant plate, avoiding direct impact on the valve body. The design of the flow holes with increasing diameter from the middle to both ends reduces the flow velocity and disperses the pressure when the fluid passes through, further reducing the impact of the fluid on the valve body, preventing fatigue, wear, and cracks in the valve body material, extending the service life of the valve body, and ensuring safe operation of the equipment.
