The three-way ball valve is a relatively new type of ball valve. It has some advantages of its own structure, such as no friction when switching, the seal is not easy to wear, and the opening and closing torque is small. This can reduce the specifications of the actuator. Equipped with a multi-turn electric actuator, it can achieve the adjustment and strict shut-off of the medium. It is widely used in working conditions that require strict shut-off, such as petroleum, chemical industry, and urban water supply and drainage.
The three-way ball valve has the following advantages:
1. The fluid resistance is small, and its resistance coefficient is equal to that of the pipe section of the same length.
2. Simple structure, small size, and light weight.
3. Tight and reliable, good sealing, and has been widely used in vacuum systems.
4. Easy to operate, open and close quickly, just rotate 90° from full open to full closed, which is convenient for long-distance control.
5. Easy to maintain, the ball valve has a simple structure, and the sealing ring is generally movable, which is convenient for disassembly and replacement.
6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and when the medium passes, it will not cause erosion of the valve sealing surface.
7. Wide application range, diameters range from a few millimeters to several meters, and can be used from high vacuum to high pressure.
According to the position of the channel, high platform ball valves can be divided into straight-through, three-way and right-angle types. The latter two types of ball valves are used to distribute the medium and change the flow direction of the medium.
The three-way ball valve relies on the rotary valve to make the valve unblocked or blocked. The ball valve is light and small in size, can be made into a large diameter, has reliable sealing, simple structure, and is easy to maintain. The sealing surface and the spherical surface are often in a closed state and are not easily eroded by the medium. It is mainly used in pipelines to cut off, distribute and change the flow direction of the medium. It is widely used in various industries.
