The ball valve can be fully closed and fully opened by rotating 90°, opening and closing quickly. Compared with the gate valve and globe valve of the same specification: the ball valve is small in size and light in weight, which is convenient for pipeline installation.
Product description:
Turbine ball valve is an important valve type, which is widely used in petrochemical, long-distance pipeline and other fields. The closing part of the ball valve is a ball (or part of the ball) with a hole, and the ball rotates with the valve stem to realize the opening or closing of the valve. Among various valves, the ball valve has the smallest flow resistance. When the full-diameter ball valve is opened, the diameter of the ball channel, the valve body channel and the connecting pipe are equal to one diameter, and the medium can flow almost without loss. The ball valve can be fully closed and fully opened by rotating 90°, opening and closing quickly. Compared with the gate valve and globe valve of the same specification: the ball valve is small in size and light in weight, which is convenient for pipeline installation.
(1) The fluid resistance is small, and the full-bore ball valve basically has no flow resistance.
(2) Simple structure, small size and light weight.
(3) Tight and reliable. It has two sealing surfaces, and various plastics are widely used for the sealing surface materials of the ball valve at present, which has good sealing performance and can achieve complete sealing. It has also been widely used in vacuum systems.
(4) Easy to operate, quick to open and close, only need to rotate 90° from fully open to fully closed, which is convenient for long-distance control.
(5) It is easy to maintain, the structure of the ball valve is simple, the sealing ring is generally movable, and it is more convenient to disassemble and replace.
(6) When fully open or fully closed, the sealing surfaces of the ball and the valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface.
(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.
(8) Due to the wiping property of the ball valve during the opening and closing process, it can be used in the medium with suspended solid particles.
