Forged steel butt weldinghigh-pressure ball valveQ61N

Three piece butt welded ball valve refers to a type of valve where the closing element is a spherical body that rotates around the centerline of the valve body to achieve opening and closing.

Ball valves are mainly used in pipelines to cut off, distribute, and change the flow direction of media. Three piece ball valve is a new type of valve widely used in recent years.

1、 The three piece butt welded ball valve has the following advantages:

1. The fluid resistance is small, and its resistance coefficient is equal to that of a pipe segment of the same length.

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

3. Tight and reliable. Currently, plastic is widely used as the sealing surface material for ball valves with good sealing performance, and 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.

2、 Characteristics and Applications of Three Piece Butt Welding Ball Valve This ball valve is mainly used to cut off or connect media in pipelines, and can also be used for fluid regulation and control. Compared with other valve types, it has the following advantages.

1. Low fluid resistance, ball valves have the lowest fluid resistance among all valve types, even for reduced diameter ball valves, their fluid resistance is quite small.

2. The thrust bearing reduces the friction torque of the valve stem, which can make the valve stem operate smoothly and flexibly for a long time.

3. The valve seat has good sealing performance, and the sealing ring is made of elastic materials such as polytetrafluoroethylene. The structure is easy to seal, and the sealing ability of the ball valve increases with the increase of medium pressure.

4. The valve stem seal is reliable. As the valve stem only rotates without lifting, the packing seal of the valve stem is not easily damaged, and the sealing ability increases with the increase of medium pressure.

5. Due to the good self-lubricating properties of materials such as polytetrafluoroethylene, the friction loss with the ball is small, resulting in a long service life of the ball valve.

6. The bottom mounted valve stem and the protruding step at the head of the valve stem prevent the valve stem from spraying out. In the event of a fire causing damage to the valve stem seal, the protruding step can also form a metal contact with the valve body to ensure the valve stem seal.

7. Anti static function: Install springs between the ball, valve stem, and valve body to dissipate static electricity generated during the switching process.
