The electric ball valve has a simple structure and is composed of only a few parts, which saves data consumption; Small size, light weight, small installation size, small driving torque, pressure regulating valve, easy and agile operation, only need to rotate 90 ° to quickly open and close; And it also has good flow regulation function and sealing characteristics. In the application range of large and medium caliber, medium and low pressure, electric ball valves are the dominant valve situation. When the electric ball valve is in the fully open position, the thickness of the butterfly plate is the only resistance for the medium to flow through the valve body. Therefore, the pressure drop that occurs through this valve is very small, and it has good flow control characteristics. Electric ball valves have two sealing types: elastic sealing and metal sealing. Elastic sealing valve, the sealing ring can be embedded on the valve body or attached around the butterfly plate. Valves with metal seals generally have a longer lifespan than those with elastic seals, but it is difficult to achieve a complete seal. Metal seals can adapt to higher operating temperatures, while elastic seals have the disadvantage of being limited by temperature. If requesting an electric ball valve for flow control, it is important to accurately select the size and type of valve.

Construction principle of electric high platform ball valve

The electric ball valve has a simple structure and is composed of only a few parts, which saves data consumption; Small size, light weight, small installation size, small driving torque, pressure regulating valve, easy and agile operation, only need to rotate 90 ° to quickly open and close; And it also has good flow regulation function and sealing characteristics. In the application range of large and medium caliber, medium and low pressure, electric ball valves are the dominant valve situation. When the electric ball valve is in the fully open position, the thickness of the butterfly plate is the only resistance for the medium to flow through the valve body. Therefore, the pressure drop that occurs through this valve is very small, and it has good flow control characteristics. Electric ball valves have two sealing types: elastic sealing and metal sealing. Elastic sealing valve, the sealing ring can be embedded on the valve body or attached around the butterfly plate. Valves with metal seals generally have a longer lifespan than those with elastic seals, but it is difficult to achieve a complete seal. Metal seals can adapt to higher operating temperatures, while elastic seals have the disadvantage of being limited by temperature. If requesting an electric ball valve for flow control, it is important to accurately select the size and type of valve. The construction principle of electric ball valves is particularly suitable for manufacturing large-diameter valves. Electric ball valves are not only widely used in general industries such as petroleum, gas, chemical, and water treatment, but also in the cooling water system of thermal power plants. The commonly used electric ball valves include clamp type electric ball valves and flange type electric ball valves. The clamp type electric ball valve is connected between two pipeline flanges with double headed bolts. The flange type electric ball valve has a flange on the valve, and the flanges on both ends of the valve are connected to the pipeline flange with bolts. The strength performance of a valve refers to its ability to withstand medium pressure. Valves are mechanical products subjected to internal pressure, therefore they must have sufficient strength and stiffness to ensure long-term use without rupture or deformation.

Outstanding advantages of electric high platform ball valve

1. The fluid resistance is small, and full bore ball valves have almost no flow resistance.

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

3. Tight and reliable. It has two sealing surfaces, and currently, various plastics are widely used as sealing surface materials for ball valves, which have good sealing performance and can achieve complete sealing. It has also been widely used in vacuum systems.

4. Easy to operate, quick opening and closing, only need to rotate 90 ° from fully open to fully closed, making it convenient for remote control.

5. Easy maintenance, simple ball valve structure, and generally movable sealing rings make disassembly and replacement relatively convenient.

When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface.

7. It has a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be used from high vacuum to high pressure.

Due to the wiping property of ball valves during opening and closing, they can be used in media with suspended solid particles.

Structural characteristics of electric high platform ball valve

1. There are locking holes in the fully open and fully closed positions of the valve to prevent accidental operation by non personnel.

2. Set a step at the lower part of the valve stem to prevent abnormal pressure rise inside the valve from dislodging the valve stem.

3. A fire-resistant sealing ring is installed between the sphere and the valve seat, which still has a sealing effect even after the valve seat is burned.

4. Quick switch, flexible opening and closing, long service life, safe and reliable.

5. Pneumatic and electric ball valves can be remotely and centrally controlled, and can meet the needs of computer program control.
