The hydraulic butterfly valve is a valve commonly used to control the flow of liquid media, but there may be various failures in actual use. Checking and solving the common faults of the hydraulic butterfly valve can ensure the normal operation of the hydraulic butterfly valve and extend its service life. Here are some common problems that may affect the normal operation of the hydraulic butterfly valve and how to solve them:
1. The valve cannot be opened or closed
If the valve of the hydraulic butterfly valve cannot be opened or closed, it is generally due to insensitive or blocked actuator action. In this case, you need to perform the following checks and handling operations:
- Check whether the air supply pressure or hydraulic pressure of the pneumatic component or hydraulic device is normal.
- Check whether the pneumatic or hydraulic pipeline of the actuator is connected properly, and whether there is air leakage or oil leakage.
- Clean the debris in the valve and piping system, remove clogging and other causes.
- Replace the damaged parts in the actuator.
2. Valve leakage, oil leakage or leakage channel
If the valve of the hydraulic-controlled butterfly valve has air leakage, oil leakage or leakage, the following inspection and treatment operations need to be carried out:
- Check the gap between valve sealing surface and sealing surface for damage or wear.
- Check the actuator or hydraulic control components for air leakage or oil leakage.
- Check whether pipe connections are loose in the pipeline system.
- Replace damaged hydraulic control components such as sealing surfaces, guides or O-rings.
3. Valve leakage or hydraulic pipeline pressure is unstable
If the valve of the hydraulically controlled butterfly valve may leak electricity or the hydraulic line pressure is unstable, the following checks and treatment operations need to be carried out:
- Check whether the electrical and hydraulic components are securely connected.
- Check whether the pressure of sealing surface or hydraulic components is uniform.
- Check whether the oil circuit in the pipeline system is balanced and whether there is oil leakage in the pipeline.
- Replace damaged or aged sealing surfaces, O-rings or pipes.
4. Valve sound, vibration or impact
If the valve of the hydraulic-controlled butterfly valve has a problem with sound, vibration or impact, the following inspection and treatment operations need to be carried out:
- Check whether the valve and the rotating parts of the pipeline are blocked.
- Check whether the pipeline system has gas buildup.
- Check whether the actuator is working properly and adjusted properly.
- Adjust the pressure and flow of hydraulic or pneumatic systems.
In short, when a problem is found with the liquid-controlled butterfly valve, the fault needs to be analyzed and solved according to the actual situation. For larger or more complex hydraulic butterfly valve failure problems, you can seek the help of professional technicians for repair and maintenance. Do timely maintenance, ensure the normal operation of equipment, to avoid the occurrence of losses.
