How To Improve The Poor Sealing of Butterfly Valves?

Date:2024-11-13View:164Tags:butterfly valves, poor sealing, valve supplier

Reasons for poor sealing of butterfly valves

1. Structural characteristics of butterfly valves

The sealing performance of butterfly valves is mainly composed of valve body, valve seat and valve. In general, due to the structural characteristics of butterfly valves, the valve seat material is simple, generally made of soft materials such as rubber or polytetrafluoroethylene, and the sealing performance is difficult to guarantee. In addition, the valve body structure and valve stem size of butterfly valves are small, and the inlet and outlet channels are also narrow, which will also affect the sealing performance.

2. Improper operation

In actual applications, the sealing performance of butterfly valves is also affected by improper operation. For example, during the opening and closing process, if the valve is not closed tightly or not tightly enough, the sealing performance will be affected.

3. Material quality

The material quality of butterfly valves will also affect its sealing performance. If the valve seat material is not suitable or the manufacturing process is not standardized, it may lead to poor sealing performance of butterfly valves.

 

The impact of poor sealing of butterfly valves

1. Liquid or gas leakage

Due to the poor sealing performance of butterfly valves, the valve is not closed tightly or not tightly enough, which may cause liquid or gas leakage. This will not only cause safety hazards in the production process, but also may cause environmental impact.

2. Unstable flow control

The poor sealing of butterfly valves will also affect their flow control capabilities. If the valve is not closed tightly, the flow control will become unstable, and the impact on the production process will also occur.

3. High maintenance costs

Due to the poor sealing of butterfly valves, maintenance is required more frequently. Maintenance generally requires downtime, which causes great inconvenience to production and increases maintenance costs.

 

How to improve the sealing performance of butterfly valves

1. Select the right materials

Choosing the right materials for the valve seat and valve can improve the sealing performance of butterfly valves. Generally speaking, valve seats made of hard materials can ensure better sealing performance.

2. Ensure correct operation

The correct operation method can effectively ensure the sealing performance of butterfly valves. For example, when closing the valve, ensure that the valve fits tightly, and when opening the valve, turn it slowly to avoid violent opening and closing.

3. Do a good job of maintenance

Regularly checking and cleaning the butterfly valve and replacing worn or aged valve seat materials can effectively improve the sealing performance of the butterfly valve. This will extend the service life of the butterfly valve and reduce maintenance costs.

 

Conclusion

After a deep understanding of the causes of poor butterfly valve sealing and its possible impact, in actual applications, users should combine the characteristics of their own production processes, conduct detailed understanding of butterfly valves with valve supplier, select appropriate butterfly valve types, and correctly operate and maintain butterfly valves to ensure their normal use and improve production efficiency.
