Operation Principle and Features of Pneumatic Three-way Ball Valve
Operation Principle of Pneumatic Three-Way Ball Valve:
1. The valve is made functional or blocked through the rotation of the valve plug. The ball valve offers easy operation, compact size, and can be made in large diameters. It provides reliable sealing, simple structure, and easy maintenance. The sealing surface and ball surface are often in a closed state, making them resistant to erosion by the medium. It is widely used across various industries. The three-way ball valve is primarily used in pipelines for cutting off, distributing, and changing the flow direction of the medium.
2. The three-way ball valve is a relatively new type of ball valve with certain advantages inherent in its structure, such as frictionless operation, low tendency to wear on the seal, and a small torque for opening and closing. This allows for a reduction in the specifications of the actuator required.
3. Equipped with a multi-revolution electric actuator, it allows for precise adjustment and tight cutoff of the medium. Widely applicable in stringent cutoff conditions such as in the oil, chemical, and urban water supply and drainage industries.
2: Features of Pneumatic Three-way Ball Valve:
1. Low fluid resistance; its drag coefficient is equal to that of a pipe section of the same length.
2. Simple structure, compact size, and light weight.
3. Tight and reliable, plastic is widely used as the sealing material for ball valves due to its good sealing properties, and they are extensively employed in vacuum systems as well.
4. Easy to operate, quick to open and close; it takes just a 90-degree rotation from fully open to fully closed, making it convenient for long-distance control.
5. Easy to maintain, the ball valve has a simple structure, and the seals are typically movable, making disassembly and replacement quite convenient.
6. When fully open or closed, the sealing surface of the sphere and valve seat is isolated from the medium. Erosion of the valve sealing surface occurs when the medium passes through.
7. Wide application range, from a few millimeters to several meters in diameter, and suitable for high vacuum pressure.
8. Multi-functional Valve: Any port can be used without leakage; a three-way valve can be made into an L-shaped port or a T-shaped port.
