The eccentric hemispherical valve and the flanged gate valve are the same type of valve. The difference is that the closing member is a sphere, and the ball rotates around the center line of the valve body to open and close a valve. The ball valve is mainly used in the pipeline to cut, distribute and change the flow direction of the medium. Two-piece ball valve, three-piece ball valve, is a new type of valve that has been widely used in recent years.
advantage
1. The fluid resistance is small, and its resistance coefficient is equal to the pipe length of the same length.
2. The structure is simple, small in size and light in weight.
High-platform ball valves can be divided into straight-through, three-way and right-angle types according to their channel positions. The latter two ball valves are used to distribute the medium and change the direction of the medium. Three-piece ball valve installation and maintenance should pay attention to the following:
1. Leave the position where the valve stem rotates.
2. Cannot be used for throttling.
3 Ball valve with belt drive should be installed upright.
working principle
It is by rotating the valve chain to make the valve unblocked or occluded. The ball valve switch is light in weight, small in size, can be made into a large diameter, reliable in sealing, simple in structure, convenient in maintenance, and the sealing surface and the spherical surface are often closed, and is not easily eroded by the medium, and is widely used in various industries.
