Where Are Stainless Steel Ball Valves Mainly Used?

Working principle of 3 Piece Ball Valve

The working principle of stainless steel ball valve is to make the valve open or closed by rotating the valve ring. The ball valve is light and small in size. It can be made into a large diameter, has reliable sealing, simple structure, and convenient maintenance. The sealing surface and the spherical surface are often in a closed state and are not easily eroded by the medium. It is widely used in various industries. Stainless steel ball valve structure diagram Ball valve and plug valve are valves of the same type, only its closing part is a sphere, and the sphere rotates around the center line of the valve body to achieve a valve to open and close. Ball valves are mainly used in pipelines to cut off, distribute and change the flow direction of the medium. Ball valves are a new type of valve that has been widely used in recent years.

Advantages of stainless steel ball valves:

1. Small fluid resistance, and its resistance coefficient is equal to that of a pipe section of the same length.

2. Simple structure, small size, and light weight.

3. Tight and reliable. At present, the sealing surface material of ball valves is widely used in plastics, which have good sealing properties and are also widely used in vacuum systems.

4. Easy to operate, quick to open and close, just rotate 90° from full open to full closed, convenient for long-distance control.

5. Easy to maintain, the ball valve has a simple structure, the sealing ring is generally movable, and it is convenient to disassemble and replace.

6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when passing through.

7. Wide range of applications, diameters range from a few millimeters to several meters, and can be used from high vacuum to high pressure. Ball valves have been widely used in various departments such as petroleum, chemical industry, power generation, papermaking, atomic energy, aviation, rockets, and people's daily life.

Uses of stainless steel ball valves:

Stainless steel ball valves are suitable for: urban construction, chemical industry, metallurgy, petroleum, pharmaceuticals, food, beverages, environmental protection The ball of the ball valve is elastic.

The ball and the valve seat sealing ring are made of metal materials, and the sealing pressure ratio is very large. Relying on the pressure of the medium itself can no longer meet the sealing requirements, and external force must be applied. This valve is suitable for high temperature and high pressure media. The elastic sphere is made elastic by opening an elastic groove at the lower end of the inner wall of the sphere. When closing the channel, the wedge-shaped head of the valve stem is used to expand the sphere and press it against the valve seat to achieve sealing. Before turning the sphere, loosen the wedge-shaped head first, and the sphere will return to its original shape, so that a small gap will appear between the sphere and the valve seat, which can reduce the friction of the sealing surface and the operating torque. Stainless steel ball valves can be divided into straight-through, three-way and right-angle types according to their channel positions. Three-way ball valves and right-angle ball valves are mainly used to distribute media and change the flow direction of media.
