Ball valve ball is floating, under the action of medium pressure, the ball can produce a certain displacement and tight pressure on the outlet sealing surface to ensure that the outlet is sealed. The structure of the floating ball valve is simple and the sealing is good, but the load of the ball bearing the working medium is all passed to the outlet sealing ring, so it is necessary to consider whether the sealing ring material can withstand the working load of the ball medium, and the ball may be offset when it is subjected to higher pressure impact. This structure is generally used for medium and low pressure ball valves. The main characteristics of the ball valve are its compact structure, reliable sealing, simple structure, convenient maintenance, sealing surface and spherical surface are often in a closed state, not easy to be washed away by the medium, easy to operate and maintain, suitable for water, solvents, acids and natural gas and other general working media, but also suitable for poor working conditions of the medium, such as oxygen, hydrogen peroxide, methane and ethylene, etc. It is widely used in various industries.

1, in a variety of valves, the flow resistance of the ball valve is the least, the full-diameter ball valve is opened, the ball channel, the valve body channel and the connecting pipe diameter are equal and form a diameter, and the medium can flow almost without loss.

2, ball valve rotation 90° can be fully closed and fully opened, open and close quickly. Compared with gate valves and globe valves of the same specifications, ball valves are small in size, light in weight, and easy to install pipelines.

1, advanced valve seat: The valve seat designed with many years of ball valve manufacturing experience, to ensure the valve seal, low friction coefficient, small operating torque, a variety of valve seat materials, wide range of adaptation.

2, switch correct handle: The use of flat head valve stem, and the connection of the handle will not be misplaced, so as to ensure that the switch state indicated by the handle and the valve address.

3, locking device: In order to prevent the valve switch misoperation, there is a locking hole in the valve fully open and fully closed position to ensure that the valve is in the correct position.

4, the valve stem flight-proof structure: the valve stem is mounted under the pressure to prevent flying out, and can form metal contact with the valve body after the fire to ensure that the valve stem seal.

5, ball valve is a ball with a round through hole as the opening and closing parts, driven by the valve stem ball around the center of the valve stem for 0~90 degrees to complete the opening and closing function; It has the characteristics of compact structure and quick switching, turning 90 degrees, you can close the valve and cut off the pipeline medium; The diameter of the ball channel is the same as that of the pipeline, and the flow resistance is small and the flow capacity is large. The valve stem is bottom-mounted, which prevents the accident of the valve stem threading and ensures the safety of use.
