Soft seal butterfly valve is the butterfly valve mainly produced by TWS Valve, including Wafer Type butterfly valve, Lug Type butterfly valve, U-Type butterfly valve, Double flange butterfly valve and Double flange eccentric butterfly valve. Its sealing performance is superior, and it is widely used in water supply, petroleum, chemical industry, metallurgy, electric power and other fields. The following will mainly introduce the structure, working principle, characteristics and application scope of the soft sealed butterfly valve.
1. Structure of the soft-sealed butterfly valve
Soft sealing butterfly valve consists of valve body, butterfly plate, sealing ring, valve stem, hand wheel and other components. The valve body is made of cast iron, cast steel or stainless steel, the butterfly plate is made of carbon steel or stainless steel, and the sealing ring is made of nitrile rubber, fluorine rubber or rubber sealing ring. Stestems are made of stainless steel and hand wheels made of cast aluminum or cast steel.
2. Operating principle of the soft-sealed butterfly valve
The soft seal butterfly valve is sealed using the friction force between the butterfly plate and the valve seat during rotation. When the butterfly valve is opened, the sealing ring on the butterfly plate presses the valve seat, making the valve seat elastic deformation and forming a seal. When the butterfly valve is closed, the sealing ring on the butterfly plate seals the valve seat, so as to realize the sealing function of the butterfly valve.
3. Features of a soft-sealed butterfly valve
1). Good sealing performance: the sealing ring of the soft sealing butterfly valve is an elastic sealing ring, which has good sealing performance and can achieve long-term sealing effect.
2). Compact structure: the soft sealed butterfly valve has a compact structure, small volume, light weight, easy to install and maintain.
3). Easy to operate: the soft sealed butterfly valve has the hand wheel, worm gear, electric and other operation modes, which can realize remote control and automatic operation.
4). Wide range of application: soft sealed butterfly valve can be used to transport a variety of corrosive medium, high temperature medium, large viscosity medium, etc., a wide range of applications.
4. Application of the soft-sealed butterfly valve
Soft sealed butterfly valve is widely used in petroleum, chemical industry, metallurgy, electric power and other fields, such as oil refineries, chemical fertilizer plant, chemical plant, power plant, etc. In these fields, the soft sealed butterfly valve can be used to transport a variety of corrosive medium, high temperature medium, large viscosity medium, etc., to ensure the safe, stable and efficient operation of the production device.
As a new type of butterfly valve, soft sealed butterfly valve has the advantages of good sealing performance, compact structure, easy operation and wide application range, and has been widely used in various industrial fields. With the continuous development of technology, the performance of soft seal butterfly valve will improve and the application scope will expand.
