Butterfly valve types and ways of use, as well as procurement precautions, maintenance, detailed introduction

Butterfly valve is a common pipeline valve, its main characteristics are simple structure, easy to operate, good sealing performance. According to the use of different occasions and functions, butterfly valves can be divided into the following categories:

1. Manual butterfly valve: mainly through manual rotation handle or gear, control valve switch and flow size.

2 pneumatic butterfly valve: through the pneumatic actuator to achieve automatic valve control, can be remote control and adjustment according to the need.

3. Electric butterfly valve: through the electric actuator to achieve automatic valve control, can achieve remote control and adjustment in different occasions.

4 stainless steel butterfly valve: made of stainless steel, has good corrosion resistance and high temperature resistance, suitable for chemical industry, medicine and other special industrial fields.

Butterfly valve is widely used, commonly seen in chemical, food, medicine, environmental protection, paper and other industries, for flow control, pressure regulation, ensure production safety. When purchasing butterfly valve, the following points need to be paid attention to:

1. Select the appropriate butterfly valve type and material according to the application scenario and fluid properties. For example, stainless steel butterfly valve is suitable for the occasions with high corrosion resistance requirements.

2. Pay attention to the match between the size of the valve and the pipeline to ensure good sealing performance and stable flow regulation.

3. Understand the reputation and product quality of suppliers, and select qualified and guaranteed suppliers for purchasing.

For the maintenance of butterfly valve, the following points need to be paid attention to:

1. Check and clean the butterfly valve regularly to ensure normal operation and prevent pollution.

2. The valve needs to be treated with anticorrosive coating to protect the valve material when it is out of service for a long time or when climate conditions change.

3. According to different materials and fluid properties, select the corresponding sealing materials and lubricants to ensure the sealing performance and smooth operation.

In short, butterfly valve as a commonly used pipeline valve, plays an important role in industrial production, correct selection and maintenance can ensure safe and stable operation.
