BQ41F insulation ball valve

1. Structure and characteristics

1. Open and close without friction: This function completely solves the problem of traditional valves affecting the sealing due to mutual friction between the sealing surfaces.

2. Top-mounted structure: The valve installed on the pipeline can be directly inspected and repaired online, which can effectively reduce device shutdown and reduce costs.

3. Single valve seat design: Eliminates the problem of abnormal pressure increase in the valve cavity media that affects the safety of use.

4. Low torque design: The valve stem with special structure design can be easily opened and closed with only a small handle.

5. Wedge-shaped sealing structure: The valve is sealed by the mechanical force provided by the valve stem to press the ball wedge onto the valve seat, so that the sealing performance of the valve is not affected by the change of pipeline pressure. The sealing performance is good under various working conditions. There is a reliable guarantee.

6. Self-cleaning structure of the sealing surface: When the sphere tilts away from the valve seat, the fluid in the pipeline passes through the sphere sealing surface at 360° uniformly, which not only eliminates the local scouring of the valve seat by the high-speed fluid, but also washes away the sealing surface The accumulation of materials, to achieve the purpose of self-cleaning.

2. Product advantages

1. The fluid resistance is small, and its resistance coefficient is equal to that of a pipe section of the same length.

2. Simple structure, small size and light weight.

3. It is tight and reliable. At present, the sealing surface material of the ball valve is widely used in plastics with good sealing performance, and it has also been widely used in the vacuum system. 4. Convenient operation, rapid opening and closing, only need to rotate 90° from fully open to fully closed, which is convenient for remote control.

5. Convenient maintenance, simple structure of the ball valve, generally movable sealing ring, easy to disassemble and replace.

6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when the medium passes.

7. It has a wide range of applications, with a diameter ranging from a few millimeters to a few meters, and can be applied from high vacuum to high pressure.
