Shanghai electric V-shaped ball valve

The Shanghai electric V-shaped ball valve switch is lightweight, small in size, can be made into a large diameter, 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 the medium. It has been widely used in various industries

The working principle of an electric V-shaped ball valve is to rotate the valve to make it open or close. Electric 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 the medium. They are widely used in various industries.

Ball valves and plug valves belong to the same type of valve, except that their closing element is a sphere that rotates around the centerline of the valve body to achieve opening and closing.

Electric V-shaped ball valves are mainly used in pipelines for fast cutting speed, distribution, and changing the flow direction of media. Threaded 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, the sealing surface material of ball valves is widely made of plastic, with good sealing performance, and 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 to maintain, pneumatic ball valve has a simple structure, and the sealing ring is generally movable, making 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.

install

1) Remove the protective covers on both sides of the flange end and rinse and clean with the valve open.

2) Before installation, the entire machine should be tested according to the specified signal (electric or gas) to prevent vibration from affecting performance during transportation. Only after passing the test can it be installed online (wiring should follow the electric actuator circuit diagram).

3) Before connecting to the pipeline, it is necessary to flush and remove any remaining impurities in the pipeline (which may damage the valve seat and ball).

4) During installation, please do not use the actuator part of the valve as a lifting point to avoid damaging the actuator and accessories. .

5) This type of valve should be installed in the horizontal or vertical direction of the pipeline.

6) The pipeline near the installation point should not have any low hanging or external force bearing phenomenon, and pipeline supports or supports can be used to eliminate the deviation of the pipeline.

7) After connecting to the pipeline, please cross tighten the flange connection bolts with the specified torque.
