Brief Introduction of 3 Piece Floating Ball Valve
The 2 piece floating ball valve and the 3 piece floating ball valve
are new types of valves that have been widely used in recent years. These types of valves should generally be installed horizontally in the pipeline. The 3 piece floating ball valve can be divided into a straight-through type, a three-way type and a right-angle type according to its channel position. The latter two ball valves are used to distribute the medium and change the direction of the medium. 3 piece floating ball valve installation and maintenance should pay attention to the following:
1. Leave the position where the valve handle rotates.
2. It cannot be used for throttling.
3. The ball valve with transmission mechanism should be installed upright.
It is mainly used in the pipeline to cut, distribute and change the flow direction of the medium. It has the following advantages:
1. The fluid resistance is small, and the resistance coefficient is equal to the pipe length of the same length.
2. Its structure is simple. It is small in size and light in weight.
3. It is close and reliable. The sealing surface material of the ball valve is widely used in plastics and has good sealing properties, and has been widely used in vacuum systems.
4. It is easy to operate, and it can be opened and closed quickly. It can be rotated by 90° from full opening to full closing, which is convenient for long-distance control.
5. It is easy to maintain. The 3 piece floating ball valve has a simple structure, and the seal rings are generally movable, and the disassembly and replacement are relatively convenient.
6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium. When the medium passes, it will not cause erosion of the sealing surface of the valve.
7. It has a wide range of applications. It is suitable for use from small to a few millimeters and as large as a few meters. It can be applied from high vacuum to high pressure. When the ball is rotated 90 degrees, all the spheres should appear at the entrance and exit, thus cutting off the flow.
The 3 piece floating ball valve has some unique features unique to its structure. For example, the switch has no friction, the seal is not easy to wear, and the opening and closing torque is small. This reduces the size of the actuators that are supplied. With multi-turn electric actuators, the medium can be adjusted and tightly closed. It is widely used in petroleum, chemical, urban water supply and drainage and other conditions that require strict cutting.
