Imported thermal insulation flange ball valve
Overview of imported thermal insulation ball valve: The thermal insulation ball valve is a relatively new type of ball valve. It has some advantages unique to its own structure, such as no friction in the switch, the seal is not easy to wear, and the opening and closing torque is small. . This allows the size of the actuator to be used reduced. Equipped with a multi-turn electric actuator, the medium can be adjusted and tightly cut off. The thermal insulation ball valve and the flange gate valve belong to the same type of valve. The difference is that its closing member is a ball. The ball rotates around the center line of the valve body to open and close the valve. Ball valves are mainly used in pipelines to cut off distribution and change the flow direction of media.
Features of the imported thermal insulation ball valve:
Self-cleaning structure of the sealing surface. When the ball tilts away from the valve seat, the fluid in the pipeline passes evenly along the sealing surface of the ball, which not only eliminates the local erosion of the valve seat by the high-speed fluid, but also washes away the accumulation on the sealing surface, achieving the purpose of self-cleaning. Opening and closing without friction. This function completely solves the problem of traditional valves affecting sealing due to mutual friction between sealing surfaces.
Wedge sealing structure. The valve relies on the mechanical force provided by the valve stem to press the ball wedge onto the valve seat to seal, so that the sealing performance of the valve is not affected by changes in pipeline pressure difference, and the sealing performance is reliably guaranteed under various working conditions. Top-loading structure. Valves installed on pipelines can be directly inspected and repaired online, which can effectively reduce device shutdowns and reduce costs.
Low torque design. The specially designed valve stem only needs a small handle to open and close the valve easily. Single seat design. It eliminates the problem of abnormal pressure increase of the medium in the valve cavity that affects the safety of use.
Preventing the valve from swelling at high temperatures comes from the fact that thermal expansion under high temperature conditions can easily cause the ball and the valve seat to swell, causing the valve to fail to open. The imported high-temperature flange ball valve adopts a disc spring or spring-loaded sealing structure. The thermal expansion of parts at high temperatures can be absorbed by the disc spring or spring. Therefore, it can ensure that the valve will not be swollen to death at high temperatures and can be used at high temperatures. Flexible opening and closing.
Adopting a unique ball grinding process, through the rotation of the ball and grinding equipment in different directions in space, the surface of the ball reaches extremely high roundness and smoothness, and the sealing performance of the valve fully meets or exceeds the standard requirements.
Imported thermal insulation ball valve product performance:
The product has good thermal insulation and cold insulation properties, and the diameter of the valve is consistent with the diameter of the pipe.
It can effectively reduce the heat loss of the medium in the pipeline.
Mainly used in various systems such as petrochemical, metallurgy, pharmaceuticals, and food to transport high-viscosity media that will solidify at room temperature.
