China ball valve type introduction: According to the structure, connection and material classification
Ball valve is a commonly used fluid control equipment, according to its structure, connection and material, can be divided into a variety of types. This article will introduce the classification of Chinese ball valves from a professional point of view.
1. Sort by structure
(1) China O-type ball valve: China O-type ball valve is the most common kind of China ball valve, its sphere is a circular cross-section, and there is a through hole inside for connecting the fluid channel. China O-type ball valve has the characteristics of simple structure, good sealing performance, light operation and easy maintenance, and is widely used in the field of fluid control in petroleum, chemical, metallurgy, electric power and other industries.
(2) China V-type ball valve: China V-type ball valve is similar to China O-type ball valve, but its sphere is V-shaped cross-section, with better sealing performance and adjustment performance. China V-type ball valve is suitable for occasions where flow, pressure and other parameters need to be precisely adjusted.
(3) China three-way ball valve: China three-way ball valve can realize the simultaneous switching of three fluid channels, which is often used in occasions where three fluid channels need to be controlled at the same time, such as heating systems, water supply systems, etc.
2. Type by connection type
(1) China flange connection ball valve: China flange connection ball valve is a kind of China ball valve that connects the valve with the pipeline through the flange, which has the advantages of easy installation and easy disassembly.
(2) Chinese thread connection ball valve: Chinese thread connection ball valve is a kind of Chinese ball valve that connects the valve with the pipeline through the thread, which has the advantages of firm connection and not easy to leak.
(3) China welded ball valve: China welded ball valve is a kind of Chinese ball valve connected by welding the valve and the pipeline, with good pressure resistance, good sealing performance and other advantages.
3. Sort by material
(1) China cast iron ball valve: China cast iron ball valve is suitable for low pressure, low temperature, non-corrosive media occasions, with cheap price, easy maintenance and other advantages.
(2) China cast steel ball valve: China cast steel ball valve is suitable for medium pressure, room temperature, non-corrosive media occasions, with high strength, good corrosion resistance and other advantages.
(3) China stainless steel ball valve: China stainless steel ball valve is suitable for high pressure, high temperature, corrosive media occasions, with good corrosion resistance, long service life and other advantages.
In short, different types of Chinese ball valves are suitable for different working conditions and environments, and users should choose the appropriate model and specification according to their own needs and use environment. At the same time, factors such as the material and sealing performance of the valve should also be considered to ensure the performance and service life of the valve.
