Vacuum ball valve use method
The vacuum ball valve is a kind of pipeline valve, which is a rotary valve with a fixed sealing structure. It realizes the control of the medium by rotating the ball, so its sealing performance is good, and it is widely used in various pipelines in petroleum, chemical, electric power, metallurgy and other industries. Below, we will understand the use of sealed ball valves.
1. Installation
Before pipe installation, check whether the material, specifications, and installation position of the vacuum ball valve meet the requirements.
Before installing the vacuum ball valve, the pipe or line should be cleaned to prevent impurities from entering. At the same time, it is necessary to check the sealing pad and sealing surface on the sealing ball valve to ensure that there is no abnormality.
When installing the vacuum ball valve, ensure that the installation direction is correct, and the direction of the ball rotation is consistent with the flow direction of the medium.
Avoid excessive tightening during installation to avoid damage to the gasket.
After installation, water leakage test is needed to check whether the sealing performance is normal.
Step 2 Use
When opening and closing the valve, rotate the stem, not the ball. Do not use the ball to tighten or loosen directly to avoid damage.
When opening or closing the valve, it should be slowly rotated to prevent the rapid ejection or backflow of the medium and damage the pipeline or valve
Doors.
For sealed ball valves that are not used for a long time, the stem should be rotated regularly to maintain its flexibility.
When using the vacuum ball valve, if there is a problem with the sealing performance, it should be inspected and maintained in time to avoid unnecessary losses.
3. Maintenance
Check the sealing pad and sealing surface of the vacuum ball valve regularly to ensure that they are intact.
The valve stem should often be coated with appropriate lubricating oil or grease to ensure its flexible operation.
The vacuum ball valve that is not used for a long time should be treated with rust prevention to prevent rust.
In the process of using the vacuum ball valve, if there is a problem, you should contact professionals in time for maintenance, do not do it without permission.
Through the above introduction, we can have a certain understanding of the use of vacuum ball valves. In the process of use, we need to pay attention to the problems of installation and operation to ensure its use effect and safety performance, and carry out regular inspection and maintenance on it to ensure the normal operation and service life of the vacuum ball valve.
2 Product Advantages
|
Reasonable structure and simple maintenance The valve body casting adopts excellent technology, reasonable structure and beautiful shape. The seat adopts elastic sealing structure, reliable sealing, easy opening and closing. |
Resistant to corrosion and stable performance The valve stem adopts the down-mounted structure with reverse seal. When the valve chamber is abnormally pressurized, the valve stem will be used Will not be flushed out. Pneumatic three-piece ball valve connection form has another butt welded (BW) socket Welded (SW) and available with international standard IS0 bracket platform and locking device. |

|
Excellent quality and wide application range It is suitable for small volume and narrow space of light industrial machinery. Pneumatic butt welding ball valve has small size, simple matching, large flow capacity, especially suitable for the medium is viscous particles, fiber nature of the occasion. |
Small size and easy to disassemble The three-piece ball valve is small in size and consists of three parts of the valve shell, which is formed by clamping the middle valve body and the valve ball from both ends through four longer bolts. Its advantage is that the maintenance disassembly does not need to remove the pipe thread, directly remove the four bolts, the middle part of the valve body can be taken out. |
