Advantages of one-piece ball valve

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

2. Simple structure, small size and light weight.

3. It is tight and reliable. At present, the sealing surface material of the ball valve is widely used in plastics with good sealing performance, and it has also been widely used in the vacuum system. 4. It is easy to operate and open and close quickly. It only needs to rotate 90° from fully open to fully closed, which is convenient for remote control.

5. Convenient maintenance, simple structure of the ball valve, generally movable sealing ring, easy to disassemble and replace.

6. When fully open or fully closed, the sealing surface of the ball and valve seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when the medium passes.
7. It has a wide range of applications, with a diameter ranging from a few millimeters to a few meters, and can be applied from high vacuum to high pressure.

B One-piece ball valve can be divided into straight-through type, three-piece ball valve and right-angle type according to its channel position. The latter two ball valves are used to distribute the medium and change the flow direction of the medium. The installation and maintenance of Canton ball valve should pay attention to the following items:

1. Leave a position where the valve handle rotates.

2. Cannot be used for throttling.

3 The ball valve with drive mechanism should be installed upright.

C The working principle of the Cantonese ball valve is to make the valve unblocked or blocked by rotating the valve. The ball valve switch is light, small in size, can be made into a large diameter, reliable in sealing, simple in structure, easy to maintain, the sealing surface and the spherical surface are often closed, and it is not easy to be eroded by the medium, and it is widely used in various industries.

D One-piece ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. Ball valve is a new type of valve that has been widely used in recent years. It has the following advantages:

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

2. Simple structure, small size and light weight.

3. It is tight and reliable. At present, the sealing surface material of the ball valve is widely used in plastics with good sealing performance, and it has also been widely used in the vacuum system.

4. It is easy to operate and open and close quickly. It only needs to rotate 90° from fully open to fully closed, which is convenient for remote control.

5. Convenient maintenance, simple structure of the ball valve, generally movable sealing ring, easy to disassemble and replace.

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

7. It has a wide range of applications, with a diameter ranging from a few millimeters to a few meters, and can be applied from high vacuum to high pressure. When the ball rotates 90 degrees, it should show a spherical surface at the entrance and exit, so as to cut off the flow.

The one-piece ball valve is a relatively new type of ball valve. It has some advantages unique to its own structure, such as frictionless switch, non-wearing seal, and small opening and closing torque. This can reduce the size of the actuator. Equipped with a multi-turn electric actuator, it can realize the adjustment and close shut-off of the medium. It is widely used in petrochemical city water supply and drainage conditions that require strict cut-off.
