1. The three-way ball valve adopts an integrated structure in structure, the sealing type of the 4-sided valve seat, less flange connections, high reliability, and lightweight design.
2. The three-way ball core is divided into T type and L type, with long service life, large flow capacity and small resistance.
3. The ball valve is divided into two types: single-acting and double-acting according to the action type. The single-acting type is characterized in that once the power source fails, the ball valve will be in the state required by the control system.
advantage:
1. The fluid resistance is small, and its resistance coefficient is equal to that of the pipe section of the same length.
2. Simple structure, small size and light weight.
3. It is tight and reliable, and the sealing surface material of the ball valve is widely used in plastic, which has good sealing performance, and has also been widely used in vacuum systems.
4. Easy to operate, quick to open and close, only need to rotate 90° from fully open to fully closed, which is convenient for long-distance control.
5. The maintenance is convenient, the ball valve has a simple structure, the sealing ring is generally movable, and it is more convenient to disassemble and replace.
6. Wide range of applications, diameters ranging from small to several millimeters, large to several meters, high vacuum or high pressure can be applied.
This type of valve is a high-pressure ball valve commonly used in existing mines. It bears high pressure and adopts U-shaped card quick connection method, which can be quickly installed and disassembled in daily production and use in mines, and is convenient to use.
