Ball Valve It Is Not Easy To Be Eroded By Media And Widely Used In Various Industries
Nov 03, 2017

The ball valve is evolved from the plug, its headstock as a sphere, the use of the ball around the axis of the stem rotation 90 degrees to achieve the opening and closing purposes. The ball valve is mainly used for cutting, distributing and changing the direction of medium flow in the pipeline, and the ball valve designed into V-shaped opening has good flow regulation function.

Ball valve is not only simple structure, good sealing performance, but also in a certain nominal diameter range of small, light weight, less material consumption, small installation size, and driving torque is small, easy to operate, easily to achieve rapid opening and closing, is the fastest development in recent more than 10 years, one of the valve varieties. Especially in the United States, Japan, Germany, France, Italy, West, Britain and other industrialized countries, the use of ball valves is very wide, the use of varieties and the number continues to expand, and to high temperature, high pressure, large-scale, high tightness, long life, excellent regulation performance and a valve multi-function direction, its reliability and other performance indicators have reached a higher level, and has been partially replaced by gate valve, globe valves, throttle valve. With the technical progress of the ball valve, it will be widely used in the foreseeable short see, especially in the oil and gas pipeline, the refinery cracking device and the nuclear industry. In addition, the ball valve will also be one of the leading valve types in the medium and low pressure areas of other industries.

The ball valve works by rotating the stem to make the valve unblocked or blocked. Ball Valve Switch Light, small size, can be made into a large caliber, sealing reliable, simple structure, easy maintenance, sealing surface and spherical surface is often closed, not easily by the media erosion, in various industries have been widely used.

Ball valve and plug valve is the same type of valve, only its closure is a sphere, the ball around the valve body centerline rotation to achieve a open, closed valve.

The ball valve is mainly used in the pipeline to cut, distribute and change the flow direction of the medium. Ball valve is widely used in recent years a new type of valve, it has the following advantages:

1. Fluid resistance is small, the resistance coefficient is equal to the same length of pipe.

2. Simple structure, small size, light weight.

3. Close and reliable, the current ball valve sealing surface materials widely used plastic, good sealing, in the vacuum system has been widely used.

4. Easy to operate, open and close quickly, from open to full off as long as 90 °, easy to control long-distance.

5. Convenient maintenance, simple structure of the ball valve, sealing ring is generally active, disassembly and replacement is more convenient.

6. In open or full closed, the ball and valve seat sealing surface and media isolation, the media through, will not cause the valve seal surface erosion.

7. Wide range of application, path from small to several millimeters, large to a few meters, from high vacuum to high pressure can be applied.

Ball valve has been widely used in petroleum, chemical, liquefied gas, water supply and drainage, food, pharmaceutical, power generation, papermaking, urban construction, mining, boiler steam system, municipal, atomic energy, aviation, rockets and other departments, as well as people's daily life.
