Stainless steel one-piece ball valveQ11F

One piece ball valve and flange gate valve belong to the same type of valve, with the difference being that their closing element is a sphere 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.

A, One piece ball valves have 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.

B, One piece ball valves can be divided into straight through type, three piece ball valves, and right angle type according to their channel positions. The latter two types of ball valves are used for distributing media and changing the flow direction of media. The installation and maintenance of wide ball valves should pay attention to the following matters:

1. Leave a position for the valve handle to rotate.

2. Cannot be used for throttling.

Ball valves with transmission mechanisms should be installed upright.

C, The working principle of a wide ball valve is to rotate the valve to make it open or close. Ball valve switches are lightweight, small in size, can be made into large diameters, reliable in sealing, simple in structure, easy to maintain, and the sealing surface and spherical surface are often in a closed state, which is not easily eroded by media. They are widely used in various industries.

D, One piece ball valves are mainly used in pipelines to cut off, distribute, and change the flow direction of media. Ball valve is a new type of valve widely used in recent years, which 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. When the ball rotates 90 degrees, it should appear spherical at both the inlet and outlet to intercept the flow.

One piece ball valve is a relatively new type of ball valve, which has some unique advantages in its own structure, such as frictionless opening and closing, low sealing wear, and small opening and closing torque. This can reduce the specifications of the accompanying actuator. Equipped with a multi turn electric actuator, it can achieve adjustment and tight cutting of the medium. Widely applicable to working conditions that require strict cut-off of water supply and drainage in petroleum and chemical cities.
