Ball valve as a common type of valve, has a wide range of applications in many fields. So, what are the types of ball valves? This article will give you a detailed introduction to the various types of ball valves to help you better understand and choose ball valve products.
1. Overview of ball valves
Ball valve is a ball as the opening and closing parts of the valve, its simple structure, easy operation, good sealing performance, widely used in petroleum, chemical, natural gas, water treatment and other industrial fields. Ball valves can be selected according to different needs and application scenarios.
Two, the type and characteristics of China ball valve
1. Classification by material:
(1) Carbon steel ball valve: mainly made of carbon steel material, with high pressure resistance, good strength, wear resistance and other characteristics, suitable for the general industrial field of pipe control system.
(2) Stainless steel ball valve: made of stainless steel material, with good corrosion resistance, suitable for corrosive media and cleanliness requirements of high occasions.
(3) Cast steel ball valve: made of cast steel material, with high pressure resistance, good impact resistance and other characteristics, suitable for high temperature, high pressure industrial fields.
2. By connection type:
(1) Threaded ball valve: threaded connection, easy to install, suitable for small diameter pipelines and equipment.
(2) Flange ball valve: through the flange connection, good sealing performance, suitable for large diameter pipelines and equipment.
(3) Welding ball valve: Through welding connection, with high strength and sealing performance, suitable for high temperature, high pressure and other special occasions.
3. Classification by structure:
(1) Floating ball valve: floating connection between the ball and the valve stem, with good sealing performance and wear resistance.
(2) Fixed ball valve: fixed connection between the ball and the valve stem, stable operation, suitable for high pressure, high temperature and other special occasions.
(3) Electric ball valve: Through the electric device to drive the ball valve opening and closing, to achieve remote control and automatic operation.
(4) Pneumatic ball valve: Through the pneumatic device to drive the ball valve opening and closing, to achieve remote control and automatic operation.
4. Classification by working principle:
(1) Manual ball valve: by manually operating the valve stem, the ball moves up and down to control the on-off of the medium.
(2) Electric ball valve: power on, through the motor to drive the valve stem, to achieve the ball up and down movement, control the media on and off.
(3) Pneumatic ball valve: through the air source to drive the cylinder, to achieve the up and down movement of the valve stem, control the ball on and off.
Iii. Conclusion
There are many types of ball valves in China, and the choice of the right ball valve needs to be considered according to the specific application scenarios and needs. Understanding the various types of ball valves helps to better choose the right products, so as to achieve the ideal use effect. I hope this article can provide you with a useful reference when choosing a ball valve.
