First, flange eccentric butterfly valve characteristics and use environment

Flange eccentric butterfly valve is a kind of fluid control equipment, its characteristics and use environment are as follows:

Features:

1. Simple structure, small volume, light weight;
2. Flexible operation, quick switch, small operation force, long service life;
3. Good sealing to prevent leakage;
4. For high viscosity media, flow control can also be achieved.

Application environment:

1. Temperature range: -40℃ to 200℃

2. Pressure range: PN1.0-1.6MPa

3. Applicable media: water, sewage, petroleum, chemical, food, medicine, etc.

Ii. Purchasing precautions

When purchasing flange eccentric butterfly valve, the following points should be paid attention to:

1. When choosing, it should be selected according to the required media characteristics, working pressure, flow rate and temperature and other factors to ensure the applicability and reliability of the selected products;

2. Manufacturers and brands with good reputation and reliable product quality should be selected;

3. It is recommended to purchase products with standard symbols for easy installation and maintenance.

Three, the detailed introduction of maintenance

The maintenance of flange eccentric butterfly valve mainly includes the following aspects:

1. Maintenance of valve shell: the shell of flange eccentric butterfly valve should be cleaned regularly to ensure its cleanliness and neat appearance;

2. Maintenance of bearings: the eccentric flange butterfly valve bearing should be lubricated and cleaned regularly to ensure its normal work;

3. Check the tightness: should regularly check the flange eccentric butterfly valve sealing performance, such as leakage problems are found in time to deal with;

4. Maintenance of valve seat: keep the valve seat clean, and regularly check and maintain it;

5. Maintain the transmission device: The valve transmission device shall be lubricated and inspected regularly to ensure its normal operation.

Maintenance needs to pay attention to the following points:

1. Read the instruction manual carefully during maintenance;

2. The power supply and medium flow of the flange eccentric butterfly valve should be disconnected during maintenance, and the valve should be removed;

3. Before maintenance, the working pressure and medium flow of the flange eccentric butterfly valve should be completely excluded;

4. After maintenance, should check the flange eccentric butterfly valve sealing performance and operation is normal, and debugging.
