The plate butterfly valve BDB-250/150 for transformers is a key component for the transformer oil tank cooling system in the power system. It plays a vital role in controlling the transformer oil circulation and protecting the transformer from overheating.

The plate butterfly valve BDB-250/150 is designed for use inside the transformer oil tank. Its working pressure and temperature must meet the needs of the transformer under various operating conditions to ensure safety and reliability. Its nominal pressure range and maximum operating temperature are important parameters for evaluating its performance. Its working pressure can be as high as 1.6 to 42MPa, and its working temperature range is wide, covering the range from -196°C to 550°C.

The material of the butterfly plate of the butterfly valve BDB-250/150 directly affects its corrosion resistance and service life in specific media. It is made of high-quality materials to adapt to transformer oil and other potentially corrosive media. For example, cast steel and stainless steel are common butterfly plate materials. They have good mechanical strength and corrosion resistance, and can resist the erosion of trace moisture and acidic substances that may exist in transformer oil.

In the BDB-250/150 model, the butterfly plate may be made of cast steel or stainless steel, or even higher-grade alloy materials to cope with various corrosive challenges that may occur in the transformer oil circulation system. In addition, in order to enhance the corrosion resistance of the butterfly plate, it will also be surface treated, such as plating or coating technology, to form a protective film to further improve its durability in harsh environments.

Maintenance and care

In order to ensure that the BDB-250/150 butterfly valve remains efficient and safe during long-term operation, regular maintenance and care are essential. This includes but is not limited to:

Regular inspection: Check the sealing performance of the butterfly valve to ensure that the seal between the butterfly plate and the valve seat is intact and there is no leakage.

Cleaning and maintenance: Regularly clean the dirt and sediment inside and outside the butterfly valve to prevent blockage and corrosion.

Lubrication maintenance: Properly lubricate the rotating parts of the butterfly valve to reduce friction and extend its service life.

Functional test: Regularly perform opening and closing tests to ensure the normal operation of the butterfly valve and detect and solve potential problems in time.
