The gas butterfly valve is a kind of ventilation pipe commonly used in metallurgy, chemical industry and other fields. It is mainly responsible for the regulation and cutting of the flow of cold and hot air containing dust. It seems that the gas butterfly valve does not seem to have an extraordinary place, but it is ordinary Compared to the valve, the structure of the butterfly valve is more suitable for this working environment.      The gas butterfly valve is made of a midline disc plate and welded steel plate, with a compact structure and light weight. The distinguishing feature from the ordinary door type valve is that it has no connecting rod, bolt, etc. structure, so it has a stronger resistance to the corrosion and damage caused by the gas transported by the channel.      The effect of increased temperature change on the valve is significant. For example, some seal materials that are relatively affected by cold and heat changes can cause damage to the internal structure due to a large temperature difference, thus affecting the normal use of the valve. But the gas butterfly valve can adapt to the normal working environment below 300°C, because its control structure is outside the valve, so it is more adaptable to the environment.     usually The gas butterfly valve adopts pneumatic control or electric control, resulting in small torque, easy operation and high reliability. Therefore, it is widely used in metallurgy, environmental protection and other fields. In addition, this kind of valve can be switched freely between manual control and automatic control, enabling more flexible use.      The use of this type of butterfly valve can replace the ball valve and gate valve to a certain extent, because it does not need to install a multi-layer seal ring, but is directly installed on the valve body, and an adjustment ring is arranged in the middle part of the valve seat and the pressure plate, so it can be more ideal. The two-way hard seal.
