The application advantages of line butterfly valve in high-performance anti-corrosion series
the application advantages of line butterfly valve in high-performance anti-corrosion series are shown in the following aspects due to the important contribution of automobile lightweight to energy conservation and emission reduction:
1. The two-piece valve rod is used with no pin connection, and the structure is simple and compact, which is very convenient for maintenance and disassembly (it can be disassembled on site); The disc plate has the function of automatic alignment (up, down, left and right), which realizes the small interference fit between the disc plate and the valve seat
2. Tongue and groove valve seat can ensure the accurate connection of the open screen switch between the valve body, valve seat and disc plate, and it is convenient to replace the valve seat at the same time
3. With the world's advanced spherical sealing pair, the sealing is more acceptable, but it is gratifying to rely on. Due to the spherical seal, the valve is smooth and excessive when opening and closing, so the friction is reduced and the torque is reduced. A low-power driving device can be selected to reduce the cost of users. At the same time, the service life of the valve seat is improved (times that of the ordinary center line valve)
4. The sealing surface of the valve seat flange adopts the structure of large wide edge and large arc, so that the valve can fully meet the requirements of socket or welded flange connection, and is suitable for connection with any standard flange
5. The axial positioning device of the valve rod adopts two gaskets and a pair of open rings, but due to the decrease of cobalt, manganese/aluminum and the structure of the spring snap ring. This can also effectively prevent the valve rod from being inadvertently disassembled, and at the same time, it can carry a certain axial force to prevent the weight of the valve rod from being transferred to the butterfly plate
6. The valve stem sealing ring plays a two-way sealing role, that is, to prevent the invasion of foreign substances and prevent the outflow of media
7. The shaft sleeve not only supports the valve rod, but also reduces the opening and closing torque. At present, there are two kinds of shaft sleeves for users to choose, namely, lubricated bronze and polytetrafluoroethylene
8. Because the valve body itself replaces the backrest of the ordinary valve seat, the overall strength of the valve is increased, so that it can reach the nominal pressure of 20kg that cannot be achieved by the ordinary centerline butterfly valve
